Catalog of Stepless Variable Transmission

A. SPT Series

B. SPTW Series

C. MYG Series

SPT series of stepless variable transmission with cone-plate and ring-plate

Introdction

SPT series of frictional stepless variable transmission is characterized by its advanced technology, introduced great general purpose, small in size, light weight, large output torque, wide range of adjusted speed, smooth running, low noise and easy operating and appraised into scientific and technological achievement in 1991 in Ningbo. It could be widely used in the field of industry where speed adjusting device is needed such as food, electronic, textile, paper-making, medicine, chemical industry etc..

Performance

1. Motor power matched: 0.37-3 kilowatt;

2. Range of variable speed: 4-5 times approximately in according with output speed 3.5-1752 rpm.

3. Variable speed either as running with load or as static.

4. Remaining a constant function when running direction of output shaft either clockwise or counter clockwise.

5. Stepless variable transmission for 0.37-3 kilowatt have two models (i.e.adujsting speed with manual and electric) and two kinds of structure (i.e. vertical and horizontal)

6. Mechanical efficiency: About 65% at low speed because of less transmission radius. Over 85% at high speed, so, please adopt high speed if possible.
