Description

Technical Field

[0001] The utility model relates to the field of wear-resistant rings, in particular to a main shaft stress-free wear-resistant ring. Background Art

[0002] The main function of the wear-resistant ring is to protect the main shaft and extend its service life. It reduces the degree of wear on the main shaft, thereby improving the operating efficiency and reliability of the entire mechanical system. The wear-resistant ring can also absorb and disperse the heat generated by the rotational motion, reducing the impact of thermal stress on the main shaft.

[0003] There is now a Chinese patent document specifically for a wear-resistant ring for a mechanical equipment main shaft, including a first fixing ring and a second fixing ring. The outer wall of the first fixing ring is integrally formed with a limiting ring, and the outer wall of the limiting ring is provided with evenly distributed positioning grooves. The outer wall of the second fixing ring is fixedly connected with a positioning column matching the positioning groove, and the outer wall of the limiting ring is sleeved with a wear-resistant unit. Through the coordinated use of the first fixing ring and the second fixing ring, the mechanical equipment main shaft can be preliminarily sealed, the wear-resistant unit is clamped by the first fixing ring and the second fixing ring, and the wear-resistant unit protects the inside of the first fixing ring. When the first fixing ring and the second fixing ring are sleeved on the mechanical equipment main shaft, the wear-resistant unit wraps the mechanical equipment main shaft to further increase its sealing performance, making its sealing performance better.

[0004] However, the above patent has certain defects when used. Since the wear-resistant unit is clamped by the first fixing ring and the second fixing ring, the structure is prone to deformation of the wear-resistant ring due to uneven distribution of clamping force, thereby having a negative impact on the rotation accuracy and stability of the main shaft.

[0005] For this reason, a spindle stress-free wear-resistant ring is proposed here to solve the above-mentioned problems. Utility Model Content
