Rack & Pinion

Rotolinear Systems has introduced a non-backlash Rack and Pinion, TCG Runner, having the distinct advantage of non-backlash, high precision, low noise, less vibration, low dust generation, extended length and smooth running, etc. The trochoidal profiled tooth enables to make a plurality of mutual teeth mesh at one time. The teeth always mesh via two or three portions and eliminate backlash when rotated in one or another direction. Instead of gears a combination of cam and roller makes a positioning accuracy and feeding accuracy as nearly as that of ballscrew structure. Rollers smoothly mesh with the optimises trochoidal tooth surface so as to avoid rattling noise, tooth striking noise and rotating noise being induced together with least amount of vibration. Due to smooth rotation, the structure dispenses with the least amount of heat and dust generated and copes with cleanroom operations. It is capable of high speed of 180 metre/minute. The company also offers Precision Lock Nuts, Bearing Reducer, Spinea, Locknuts (Precision), High Precision Reducer, Ground Ball screws, LH-RH Combination, etc.
