Features of roller cam transmission

 

  • No backlash

Roller and cam rolling transmission, no forward and reverse backlash problems, improve the ultra-precision and special characteristics of rollers and cams, reduce the difficulty of assembly, and improve quality.

  • High efficiency transmission

Roller and cam rolling transmission, reducing wear, high transmission efficiency, the transmission efficiency is as high as 90% when running at high speed.

  • No thermal displacement

Under high-speed operation, reduce wear. Reduce thermal displacement.

  • Maintenance-free

Due to low abrasion and minimal aging, the initial accuracy can be maintained for a long time.

  • Excellent braking

When the brake is positioned, the disc surface will not float or tilt, and the positioning brake is kept within 0.002mm, which is a breakthrough in finishing technology.

  • Firm structure

Using the latest YRT bearing support, high rigidity, heavy load.

 

No maintenance and excellent price/performance ratio

 

  • Turbine shaft

Accuracy decreases over time and requires regular maintenance to reach or approach initial accuracy.

  • Backlashless roller

The accuracy is consistent within 5 million operation cycles and requires no maintenance.

  • Turbine shaft

Maintenance is required once or twice a year to adjust the rebound of accuracy.

  • Backlashless roller

Long-term use does not require any maintenance.

Different processing modes improve efficiency

 

  • Turbine shaft

In 90-degree positioning, the brake mechanism needs to be tightened to suppress backlash.

  • Backlashless roller

Zero clearance and high rigidity do not require clamping, no brakes are required for light-load processing, and positioning time is reduced to about 1/3.
