UDL Series Mechanical Stepless Speed Variator

UDL Series Mechanical Stepless Speed Variator

A mechanical stepless speed variator(UDL Series) is an ideal solution for any application that requires a variable output speed. These devices are a combination of two conical disks that rotate in opposite directions, and it can 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 one of these devices, contact us, We manufactures them at affordable prices and with reliable features.
The mechanical speed variator is a functional unit that comprises two parts: one above the drive shaft and another underneath. The two segments are separated by a space, and calculate their surfaces ,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 two parts is equal, and they are in a dynamic balance.

UD series planetary friction mechanical stepless speeds vary the output speed. The device is working 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 seven different sizes and 200 versions and has multiple mounting positions. The device is fully dry and consists of two conical metallic disks and two 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. Used in cars, trucks, and boats. And 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 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 one full rotation and its output speed can be returned to the original speed with less than five 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. Applications: 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 three main parts: a power input axle and two planetary gear systems. The first member: connect to the power input axle and shunt 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 working with 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 two categories: planetary, single and dual-shaft models. UDL series is a planetary type of speed variation.
In addition, we can custom the mechanical speed variator to meet the requirements of different users and industries. For instance, the variable-speed motor has an automatic control and a manual-adjustable speed.
