The worm gear box is a rotary drive device, which has a XNUMX-degree rotation and a XNUMX-degree rotation. It is a device with very good performance.Worm gear box is a kind of driving device that is very useful in daily life, because it is small and easy to carry, the design is also very reasonable, the application range is very wide, and it is matched with various valves.So what is the inspection standard for the worm gear box?
1. Worm gear box size
1.1 The size, shape and shape tolerance of the installation part meet the requirements of the drawing; 2.2 The shaft diameter and the size meet the requirements of the drawing;
2. Appearance of worm gear box:
2.1 All kinds of fasteners are not under-installed, missed, or incorrectly installed, and there is no cutting residue in the threaded hole, and no shrinkage phenomenon; 1.3 The product qualification certificate, instruction manual, safety standard certificate, and factory inspection report are required;
2.2 The coating of the shell should be uniform, no leakage, air bubbles, blank, accumulation, paint bumps are allowed, and it should be firmly combined with the surface of the covering without shrinkage and layering;
3. Worm gear box performance
3.1 To test the meshing performance, the overall rotation should be flexible and free from jamming, and the occlusal gap should not be too large;
3.2绝缘电阻：在常温和相对湿度小于80%条件下，各通电部分间的绝缘电阻应大于20MΩ; 3.3空载试验 在额定转速下，正、反向运转应各不小于1h;
1- Smooth operation, no impact, no abnormal vibration and noise;
2- There is no oil leakage at all seals and joints;
3- There is no gap impact, dead spots, jamming, smooth movement and no bad phenomena;
The above are the three inspection standards of the worm gear box. I hope that through this article, everyone can have a deeper understanding of the worm gear box. Generally speaking, the worm gear box is a very good driving device.
