Double-nut ball screw gap of inspection and maintenance by detecting the distribution of imported grinding HIWIN ball screw, lead screw if to confirm the fault is not due to traverse due. It would have to consider whether it is creating a gap between the screw nut, the detection method to detect this situation is basically the same as the screw ran. Using a dial indicator to measure and nut packaging machinery connected to the bench with a ball screw, ball screw forward and reverse rotation of the screw, to detect the maximum gap between the screw and nut, and then make adjustments. 5. Block nut or nut bearing seat if less rigid or less rigid bearing, due to the weight of the element itself or machine load will deflect it. This mode is used to detect the rigidity of the nut seat, a similar test can also be used to detect bearing rigidity. 6. nut seat or improper bearing assembly (1) due to vibration or reinforcement insurance reform so that the element loose. To replace the spring pin solid pin positioning to achieve the purpose. (2) because the screws are too long or too shallow hole screw nut seat makes the screws can not lock nut. (3) due to vibration or missing spring washer so that the screws loose nut 7. parallel to the surface of the support base or flatness tolerances over whether binding element surface is abrasive grinding or scraping HIWIN ball screw distributor, as long as the parallelism or flatness beyond the tolerance range, reproducible precision motion position when the bed units will poor; therefore a machine usually between the seat and the machine body to support shims to achieve its objective. Imported grinding ball screw HIWIN distribution, transmission machinery Korea and Taiwan, the ball screw is provided by Dongguan Transmission Machinery Co., Korea and Taiwan.
