AI Technical Summary

Technical Problem

In existing compressor spindle swashplate assemblies with noise reduction and vibration damping, the lower end of the limit spring rubs against the surface of the swashplate, generating noise that affects the operating environment.

Method used

Design a noise-reducing and vibration-damping compressor spindle swashplate assembly. By adding a limiting mechanism and a vibration-damping mechanism to the swashplate, and using rubber pads and anti-slip grooves to reduce friction noise, including the sliding connection between the slider and the connecting block and the anti-slip groove design of the rubber pads.

Benefits of technology

It effectively reduces axial impact and frictional noise between the swashplate and the spindle, improving the quality of the operating environment.

Abstract

一种可降噪减震压缩机主轴斜盘总成，包括主轴和挡圈，所述主轴的内壁与挡圈活动连接，所述挡圈的内壁与固定螺丝螺纹连接，所述挡圈的内壁与弹簧固定连接，所述主轴的外壁与斜盘滑动连接，所述斜盘的下端连接有限位机构。通过斜盘沿着主轴的轴线方向往复移动，斜盘固定块上的滑块在连接块的内壁滑动，也能够减少斜盘与主轴的轴向冲击力的效果，并且弹簧的端部与斜盘接触之间增加橡胶垫，避免弹簧的端部与主轴之间摩擦产生的噪音，橡胶垫表面加工的防滑槽与弹簧起到活动限位的效果，避免弹簧变形出现偏离与主轴的外壁出现接触产生摩擦噪音，降低限位弹簧的下端与斜盘的表面会产生摩擦的噪音，提升使用环境的质量。
