The roller is assembled by a certain number of rollers and roller racks, and the rollers roll on the tooth surface of the rack when engaged
Based on the above structure, the product has the following characteristics:1, zero backlash: when the roller and rack (gear ring) meshing, you can achieve zero backlash, you can apply pre pressure, thereby greatly improving the repeatability of positioning accuracy and transmission accuracy.2, high precision: its transmission accuracy can reach + 0.02mm, repeated positioning accuracy up to + 0.01mm, corner accuracy can reach + 50 seconds. Approach lead precision.3 、 low noise and low vibration.
4, long distance transmission: because the rack can be spliced and assembled, and compared with the screw, its biggest advantage is that it can realize long distance precise drive.5, long life: as a result of rolling meshing, so far below the ordinary wear gear rack.6 、 low wear and low dust, apply to level 1000 clean room7, a wide range of applications: application of roller rack and gear wheel is very wide, such as bench loaders, long distance walking robot, synchronous feeding, long stroke mechanical equipment, compound rolling head, measuring instrument, stacker, cleaning line, synchronous drive, can freely set the table, the rotation of the robot the driving machine, observation and so on are widely used
The roller is composed of a certain number of roller and roller assembly, engaged in roller rack on the tooth surface, which greatly reduces the friction engagement, improve meshing accuracy, reduce wear; the toothed rack and the gear ring is designed according to the characteristics of rolling wheel, involute shape different from universal rack, better able to engage and roller
