AI Technical Summary

Technical Problem

In the existing technology, the disassembly of the dust cover of cylindrical roller bearings relies on manual operation, which makes the dust cover prone to deformation, warping or tearing, resulting in a high defect rate, low efficiency and increased labor costs.

Method used

Design a disassembly tool that includes a fixed plate, connecting rod, push plate, and cylindrical support. Utilize a press to provide uniform axial force, and achieve non-destructive disassembly through the large-area contact between the push plate and the dust cover. Combined with chucks to fix the outer ring of the bearing, ensure the stability and efficiency of the disassembly process.

Benefits of technology

It effectively avoids local deformation of the dust cover, reduces the defect rate, improves disassembly efficiency, reduces material and labor costs, adapts to the versatility and adaptability of different bearing models, and meets the needs of large-scale production.

Abstract

本实用新型涉及轴承技术领域，尤其是涉及一种圆柱滚子轴承防尘盖的拆卸工具，包括与压力机固定连接的固定板，所述固定板沿压力机运动方向固定设有连杆，所述连杆的端部连接有推板，所述推板的外缘处设有多个供滚子穿过的缺口。本实用新型通过推板与防尘盖的大面积接触，配合压力机提供的均匀且稳定的轴向力，有效避免了传统人工借助螺丝刀、撬棍等简易工具时因施力点分散、受力不均导致的防尘盖局部变形、翘曲或撕裂问题。防尘盖在均匀外力作用下沿轴承外圈平稳脱离，最大程度保留了其结构完整性，显著降低了残品率，不仅节约了材料成本，还为防尘盖的二次利用提供了可靠保障。
