1) Aluminium alloy die cast casing for RV 571,030,040,050,063,075,090,light w8 and non-rustingcast iron casing for RV110,130,150.

two) massive output torque.

3) stable transmission with reduced sound.

four) large geat-radiation efficiency.

5) elegant form,modest volume and tough serving existence

six) suitable for omnibearing set up


The design of UDL series planet c1disk stepless speed variator compromises the advanced technology both at home and abroad. 

The products include the following main characteristics:

one) High speed regulating precision,up to 0.5-1 rotation

2) Large speed changing range:the speed ratio ranges from 1:4 to 1:7 freely

three) High in strength and long in service life

4) Convenient to regulate the speed

five) Continuous in running, front to back in running direction,smooth in driving,stable in performance and low in noise

six) Full in sealing and suitable for any environment

7) Compact in structure and small in volume

8) Made of high-quality aluminium alloy diecast into forming,good surface,light in w8 and it never gets rusty

nine) Good in adaptation: UDL series planet c1-disk stepless speed variators can be combined with all kinds of speed reducers as to achieve low stepless speed changing

UDL series planet c1 disk stepless speed variators are widely used for foodstuffs,ceramics,packing,chemical substances,pharmacy,plastics,paper making, mchine-equipment, transportation,and all kinds of automatic production lines,pipelines and assembly lines which need is a good companion for your production.

The phrase “gearbox” is utilized to refer to any device that connects a motor to a machine and is composed of a series of gears, also known as a gear set. It receives the primary enter pace from the motor and modifications it to a various output pace using its gears. Various kinds and combos of gears serve specific purposes. The varieties of gears found in gearboxes incorporate spur gears, bevel gears, helical gears, helical gears and worm gears. The efficiency effectiveness of a gearbox is represented by the gearbox ratio, which is the ratio of the speed of the enter supply to the velocity of the output resource
These compact, light-weight, minimal backlash inline gear reducers ended up originally developed for encoder programs. They are also suitable for a lot of other travel techniques. Encoder gear reducers have a very lower instant of inertia at the shaft enter and are rated for enter speeds up to 3000 rpm. Two body sizes are offered with gear ratios from 4.96:1 to 3600:1. Our encoder gearbox sync pads are accessible from stock.
