About torsion axle

Torsion axles offer a low-maintenance, reliable, quiet, smooth ride. Mastervim torsion axles make it simple to have peace of mind while trailer towing.

Torsion axles have taken the trailer industry by storm in recent years. The boom in usage can be attributed to the many benefits that torsion axles offer over standard spring axles. Their innovative design provides an array of benefits and avoids many of the shortfalls that have commonly been found in traditional spring axles. 
 

Torsion Axle Benefits

No Maintenance

Torsion axles have a very simple design, using rubber cords and an inner bar, rather than the large array of parts found in a spring axle. The simplicity of this design means that there is little to no maintenance that needs to be done. All you have to do is lube your wheel bearings.
 
Smooth, Quiet Ride
Torsion axles function using a simple design that utilizes the compression of rubber cords inside the axle to cushion the trailer. This twisting and compression motion is very smooth and it rides nicely even when there is no load. Furthermore, there is no metal-to-metal contact inside the axle making it quieter and less abrasive. 
 

Reliable

Torsion axles have fewer moving parts than traditional forms of trailer suspension. As mentioned earlier, there is no metal-to-metal contact within the axles components. This means that there are no CZPT parts rubbing against each other, causing wear or corrosion. Likewise, the rubber construction means that the axles are more corrosion resistant. 
 

Versatility

Torsion axles can be used in an extensive range of applications, due to the ease of adjustment. To change the height of a torsion axle, the torsion bars just need to be adjusted. Additionally, half-torsion units can be used, meaning that the application does not need an axle that passes under the entire trailer. This opens up the opportunity for many custom applications and can provide benefits such as additional ground clearance.
 

When is it better than a Spring Axle?

They are particularly advantageous over springs axles for applications like:

  • Marine/Boat trailers
  • Rough/bumpy surfaces
  • When much lower or higher ride height is needed
  • High vibration applications (like wood chippers or generators)
  • Custom applications
  • Applications with limited mounting space 
  • Corrosive environments (like saltwater)

Torsion Axles can improve your trailer-towing experience.

What Is a Worm Gear Reducer?

If you have never seen a worm gear reducer before, you’re missing out! Learn more about these incredible gears and their applications by reading this article! In addition to worm gear reducers, learn about worms and how they’re made. You’ll also discover what types of machines can benefit from worm gears, such as rock crushers and elevators. The following information will help you understand what a worm gear reducer is and how to find 1 in your area.

Typical worm shaft

A typical worm has 2 shafts, 1 for advancing and 1 for receding, which form the axial pitch of the gear. Usually, there are 8 standard axial pitches, which establish a basic dimension for worm production and inspection. The axial pitch of the worm equals the circular pitch of the gear in the central plane and the master lead cam’s radial pitch. A single set of change gears and 1 master lead cam are used to produce each size of worm.
Worm gear is commonly used to manufacture a worm shaft. It is a reliable and efficient gear reduction system that does not move when the power is removed. Typical worm gears come in standard sizes as well as assisted systems. Manufacturers can be found online. Listed below are some common materials for worm gears. There are also many options for lubrication. The worm gear is typically made from case hardened steel or bronze. Non-metallic materials are also used in light-duty applications.
A self-locking worm gear prevents the worm from moving backwards. Typical worm gears are generally self-locking when the lead angle is less than 11 degrees. However, this feature can be detrimental to systems that require reverse sensitivity. If the lead angle is less than 4 degrees, back-driving is unlikely. However, if fail-safe protection is a prerequisite, back-driving worm gears must have a positive brake to avoid reverse movement.
Worm gears are often used in transmission applications. They are a more efficient way to reduce the speed of a machine compared to conventional gear sets. Their reduced speed is possible thanks to their low ratio and few components. Unlike conventional gear sets, worm gears require less maintenance and lower mechanical failure than a conventional gear set. While they require fewer parts, worm gears are also more durable than conventional gear sets.
There are 2 types of worm tooth forms. Convex and involute helicoids have different types of teeth. The former uses a straight line to intersect the involute worm generating line. The latter, on the other hand, uses a trapezoid based on the central cross section of the root. Both of these tooth forms are used in the production of worms. And they have various variations in pitch diameter.

Types of worms

Worms have several forms of tooth. For convenience in production, a trapezoid-based tooth form is used. Other forms include an involute helicoidal or a convolute worm generating a line. The following is a description of each type. All types are similar, and some may be preferred over others. Listed below are the 3 most common worm shaft types. Each type has its own advantages and disadvantages.
Discrete versus parallel axis: The design of a worm gear determines its ratio of torque. It’s a combination of 2 different metals – 1 for the worm and 1 for the wheel – which helps it absorb shock loads. Construction equipment and off-road vehicles typically require varying torques to maneuver over different terrain. A worm gear system can help them maneuver over uneven terrain without causing excessive wear.
Worm gear units have the highest ratio. The sliding action of the worm shaft results in a high self-locking torque. Depending on the angle of inclination and friction, a worm gear can reach up to 100:1! Worm gears can be made of different materials depending on their inclination and friction angle. Worm gears are also useful for gear reduction applications, such as lubrication or grinding. However, you should consider that heavier gears tend to be harder to reverse than lighter ones.
Metal alloy: Stainless steel, brass, and aluminum bronze are common materials for worm gears. All 3 types have unique advantages. A bronze worm gear is typically composed of a combination of copper, zinc, and tin. A bronze shaft is more corrosive than a brass one, but it is a durable and corrosion-resistant option. Metal alloys: These materials are used for both the worm wheel.
The efficiency of worm gears depends on the assembly conditions and the lubricant. A 30:1 ratio reduces the efficiency to 81:1%. A worm gear is more efficient at higher ratios than an helical gear, but a 30:1 ratio reduces the efficiency to 81%. A helical gear reduces speed while preserving torque to around 15% of the original speed. The difference in efficiency between worm gear and helical gear is about half an hour!

Methods of manufacturing worm shafts

Several methods of manufacturing worm shafts are available in the market. Single-pointed lathe tools or end mills are the most popular methods for manufacturing worms. These tools are capable of producing worms with different pressure angles depending on their diameter, the depth of thread, and the grinding wheel’s diameter. The diagram below shows how different pressure angles influence the profile of worms manufactured using different cutting tools.
The method for making worm shafts involves the process of establishing the proper outer diameter of a common worm shaft blank. This may include considering the number of reduction ratios in a family, the distance between the worm shaft and the gear set center, as well as the torques involved. These processes are also referred to as ‘thread assembly’. Each process can be further refined if the desired axial pitch can be achieved.
The axial pitch of a worm must match the circular pitch of the larger gear. This is called the pitch. The pitch diameter and axial pitch must be equal. Worms can be left-handed or right-handed. The lead, which refers to the distance a point on the thread travels during 1 revolution of the worm, is defined by its angle of tangent to the helix on the pitch of the cylinder.
Worm shafts are commonly manufactured using a worm gear. Worm gears can be used in different applications because they offer fine adjustment and high gear reduction. They can be made in both standard sizes and assisted systems. Worm shaft manufacturers can be found online. Alternatively, you can contact a manufacturer directly to get your worm gears manufactured. The process will take only a few minutes. If you are looking for a manufacturer of worm gears, you can browse a directory.
Worm gears are made with hardened metal. The worm wheel and gear are yellow in color. A compounded oil with rust and oxidation inhibitors is also used to make worm gears. These oils adhere to the shaft walls and make a protective barrier between the surfaces. If the compounded oil is applied correctly, the worm gear will reduce the noise in a motor, resulting in a smoother performance.

applications for worm gear reducers

Worm gears are widely used in power transmission applications, providing a compact, high reduction, low-speed drive. To determine the torque ratio of worm gears, a numerical model was developed that makes use of the equation of displacement compatibility and the influence coefficient method, which provides fast computing. The numerical model also incorporates bending deflections of the gear surfaces and the mating surfaces. It is based on the Boussinesq theory, which calculates local contact deformations.
Worm gears can be designed to be right or left-handed, and the worm can turn either clockwise or counter-clockwise. An internal helical gear requires the same hand to operate both parts. In contrast, an external helical gear must be operated by the opposite hand. The same principle applies to worm gears in other applications. The torque and power transferred can be large, but worm gears are able to cope with large reductions in both directions.
Worm gears are extremely useful in industrial machinery designs. They reduce noise levels, save space, and give machines extra precision and fast-stopping capabilities. Worm gears are also available in compact versions, making them ideal for hoisting applications. This type of gear reducer is used in industrial settings where space is an issue. Its smaller size and less noise makes it ideal for applications that need the machine to stop quickly.
A double-throated worm gear offers the highest load capacity while still remaining compact. The double-throated version features concave teeth on both worm and gear, doubling the contact area between them. Worm gears are also useful for low to moderate-horsepower applications, and their high ratios, high output torque, and significant speed reduction make them a desirable choice for many applications. Worm gears are also quieter than other types of gears, reducing the noise and vibrations that they cause.
Worm gears have numerous advantages over other types of gears. They have high levels of conformity and can be classified as a screw pair within a lower-pair gear family. Worm gears are also known to have a high degree of relative sliding. Worm gears are often made of hardened steel or phosphor-bronze, which provides good surface finish and rigid positioning. Worm gears are lubricated with special lubricants that contain surface-active additives. Worm gear lubrication is a mixed lubrication process and causes mild wear and tear.
