The invention discloses a design method for a quick decomposition method of a compact rolling bearing of a railway. The utility model is suitable for the bearing decomposition of the general maintenance of a compact rolling bearing of a railway. The structure of the machine can be designed as a single station or connected with the production line. The machine drives the hydraulic system or pneumatic system, and performs the operation by means of electrical logic control. The machine can be designed by the two machine two times to complete decomposition, decomposition and decomposition of bearing shell bearing inner ring is a machine, the decomposition of bearing inner and outer ring and the bearing sealing ring is a single machine; can also be two times two times to complete the operation be made one decomposition, decomposition of bearings in the same integrated machine. The machine is mainly composed of a base bearing rapid decomposition, the left and right frame frame body frame, a vertical oil cylinder and a horizontal cylinder to drive the unloading unit, unloading bearing shell and the inner ring, in the horizontal cylinder is arranged at the front end of dismounting eccentric bearing plate, pushing the septal ring through the eccentric plate against the end surface of the bearing outer ring, and the fixed bearing shell bearing inner and outer ring; decomposition and sealing ring, is through the use of vertical oil cylinder top bearing inner and outer ring, and the use of a special circular top cover of the bearing outer ring and bearing ring decomposition.

本专利技术提供一种,属于铁路货车制造、检修自 动化专用设备
技术背景公知的铁路紧凑型滚动轴承是一种新型的滚动轴承,这种铁路滚动轴承的 密封罩及内外环及轴承外壳之间都采用压装装配,轴承外壳与内圈之间、轴承 内外环与密封罩之间等都具有一定装配力,因此在轴承检修分解时就必须施加 一定的退卸外力。传统上使用人工或简易手工工装完成,这种工艺方法不但效 率低,劳动强度大,容易损坏轴承组件和碰伤操作者,而且轴承检修成本也较 高。为了解决铁路紧凑型滚动轴承分解采用人工或简易手工工装完成的现状, 本专利技术提供了 一种使用机电一体化装置进行铁路滚动轴承快速分解的方法,此 方法能够进行快速分解铁路轴承,且不损坏轴承组件,保证了轴承的分解质量,比人工分解提高5倍效率,同时保证了操作者的人身安全,减轻了操作者的劳 动强度,提高了经济效益,彻底的解决了铁路紧凑型滚动轴承分解难题。
技术实现思路
实现轴承快速分解方法的核心内容是该机器采用偏心的退卸顶块, 定位在轴承中隔圈位置,并使其偏离轴承的中心线,通过液压缸或气动缸 推动,来完成轴承外壳和轴承内圈的分解;同样在该机器上(或单独 ...
【技术保护点】
一种铁路滚动轴承快速分解方法,其权力要求特征是:通过偏心机构分解铁路轴承的外壳与轴承内圈(轴承内圈包括轴承内、外环、轴承中隔圈),通过液压(可选气动系统)方式分解内圈与密封罩的方法。分解方法由两个步骤完成,第一步骤是将内环、外环、中隔圈与轴承外罩分解。方法是:轴承水平放置,由一个能水平方向伸进轴承内圈内径的圆柱形液压活塞作为退卸缸进行退卸。由于轴承内圈的内径接近等直径,一般无法找到退卸断面,因此本方法在油缸退卸头的前端安装偏心的退卸圆盘顶块。分解轴承外壳与轴承内圈时,将偏心圆盘顶块先运行到轴承的中圈隔离环位置,通过偏心圆盘使中隔圈位置与轴承内圈的内径不在同一轴线上,这样偏心 ...
