A mechanical stepless speed variator is an ideal solution for any application that requires a variable output speed. These devices are a combination of 2 conical disks that rotate in opposite directions, and can be used to control the speed of an engine, fan, or any other device. In addition to being maintenance-free, mechanical speed variators also feature life-time lubrication. If you need 1 of these devices, contact us, HZPT, who manufactures them at affordable prices and with reliable features.
The mechanical speed variator is a functional unit that comprises 2 parts: 1 above the drive shaft and another underneath. The 2 segments are separated by a space, and their surfaces are calculated by using the angular speed of the barycenter of the relevant segment and the distance between the barycenter and the main axis of rotation. The summation of the 2 parts is equal, and they are in a dynamic balance.
Types of Stepless Speed Variators
Whether you’re looking for a stepless speed variator for your automotive needs, or you want a variable-speed control for your home or business, you’ve come to the right place. There are various types of stepless speed variators. UDL series mechanical stepless speed variator, and the UD series planetary friction mechanical stepless speed variator.

The device is widely used in various industries for its high speed-regulating precision, large changing range and long service life. The UD series stepless speed variator has low noise, continuous running, and smooth transmission. This device can be used to change the output speed from low to high without changing the drive shaft. The UDL series stepless speed variator can be installed in any place that requires speed-changing.
The UD series planetary friction mechanical stepless-speed variator features integral motor flange and fully modular output flange. It is available in 7 different sizes and 200 versions and has multiple mounting positions. The device is fully dry and consists of 2 conical metallic disks and 2 friction discs built in synthetic fibra. They have a wide range of speed variations and can meet different speed requirements.
The UD series planetary friction mechanical stepless-speed variators are widely used in the field of automotive applications. They are used in cars, trucks, and boats. They have many benefits over conventional mechanical stepless-speed variators. They feature an adjustable-speed planetary system and an improved power transmission system. Their superiority is the combination of high-quality design and high-precision manufacturing.
Features of UDL Series Stepless Speed Variator
The UDL series planetary friction mechanical stepless speed variator is a modular design that provides high precision speed regulation and repeatability. Its speed regulation accuracy is one-half to 1 full rotation and its output speed can be returned to the original speed with less than 5 percent error. Its simplified structure enables fast and energy-efficient operation. The four-pole motor has a wide range of output speeds.
The UDL series planetary friction mechanical stepless speed variator is an excellent example of the concept of a continuous-variable transmission. It has a long history and a good reputation for long-term use, with many decades of development and use. With its simple design and stable transmission, it is used extensively in food machinery, rubber, ceramic, and pharmaceutical production lines. The low friction of this model results in little wear of the discs.
The UDL series planetary friction mechanical stepless speed variator comprises 3 main parts: a power input axle and 2 planetary gear systems. The first member is connected to the power input axle and shunted to the second. The first planetary gear system synthesizes power and outputs it through the second member of the planetary gear system. The second planetary gear system, which is meshed by the overrunning clutch piece 2, serves as the power output of planetary gear 3/4 member.
The Mechanical Speed Variator Principle
The mechanical speed variator works on a simple but well-balanced principle: the first mass of the speed variator is driven into rotation by a drive shaft. The cam is housed inside a circular hole in the first mass, which has a center that is not parallel to the main axis of rotation. When this shaft is turned, the lower mass is driven into rotation by a second mass. This mechanism allows the motor to control the speed of the drive shaft, thereby maintaining the required level of torque.
The mechanical speed variator principle is simpler than its hydraulic counterpart. Instead of a hydraulic pump, the mechanical stepless speed variator uses gears inside the machine to change the output speed and torque. This means that the speed of the engine can be controlled over a wide range of speeds while maintaining the engine’s efficiency. Moreover, a mechanical motor speed variator can be found in many industrial settings. A mechanical speed variator can be divided into 2 categories: planetary, single and dual-shaft models. UDL series is a planetary type of speed variation.
In addition, the mechanical speed variator can be customized to meet the requirements of different users and industries. For instance, the variable-speed motor has an automatic control and a manual-adjustable speed.
