Roller screw rotary-to-linear movement converter - has threaded rollers engaging threaded spindle within bore housing

摘要

The circulating roller spindle system converts rotating movement into straight line movement. The cage (4) for rollers floats freely between the threaded spindle (1) and the enclosing threaded housing (3). The rollers (2) can be arranged also without a cage. The spindle (1), rollers (2) and housing are combined to ensure optimum movement. The rotating movement of the spindle is transmitted to the housing (3) which moves in a straight line or vice versa. The screw threads of rollers engage with the screw threads in the housing and in the spindle.
