Improper combination motor and ball screw (1) combined with weak or poor coupling itself rigid, resulting in rotational difference (relative rotation) between the screw and the motor makes. (2) if they fit with gear drive or drive structure is not rigid, available Timing belt to drive to prevent slippage. (3) key loose, or with any improper key, keyway, hub between all make a gap between these components. A2-2 not smooth actuation screw machining problems 1. (1) screw or nut bead groove surface roughness. (2) steel ball, screw or nut roundness out of tolerance. (3) The lead screw or nut errors or pitch circle diameter out of tolerance. Improper (4) the return conduit assembly. (5) steel ball size or uneven hardness. The above problems should not happen in a high-quality product is. Note: If precision is no problem, then you can re-testing under screw beating, For now the truth is there is no better way to detect, and it says that even the most basic detection method is the most effective. As for how the election screw, generally you should determine the precision ball screw High Wycombe, will be determined after a good load, the motor speed there is walking distance Yuhuan ball screw, which are given after a good screw diameter substantially Model to determine the Rolled ball screw, and then determining the preload, the preload grinding stage should be P2 or P3 is no gap Light preload or pre-press, etc., this is no way to use the instrument to detect.
