Description

Technical Field

[0001] The utility model relates to the technical field of ball screws, in particular to a ball screw transmission efficiency testing device. Background Art

[0002] The ball screw is an ideal product for converting rotary motion into linear motion, or vice versa. After the screw is manufactured, the transmission efficiency of the screw will be tested. This test device is used to test the transmission efficiency of the screw.

[0003] When testing a ball screw, the screw is driven and the screw is driven through a nut or a screw seat. The transmission efficiency of the screw is detected by testing the displacement distance of the screw seat or the nut during transmission. However, the test device generally has a simple structure and requires multiple screws to limit the positioning of the screw and nut of the screw. When replacing a new screw, the screws need to be turned and the screw needs to be disassembled and assembled, resulting in poor testing efficiency. Utility Model Content
