Bearing assembly dismounting and mounting tool

Abstract

The invention relates to the field of large equipment maintenance, in particular to a bearing assembly dismounting tool. A bearing assembly dismounting and mounting tool comprises a movable platform,a power source, a driving device, a bracket assembly, a chuck connection assembly and a shaft neck clamping assembly; and a structural frame is fixedly mounted on a shell of the driving device and provided with a first positioning face and a second positioning face, the chuck connection assembly is mounted on the first positioning face, the shaft neck clamping assembly is mounted on the second positioning face, thus when the shaft neck clamping assembly clamps a main shaft of a bearing assembly, the axis of the chuck connection assembly is parallel with the axis of the main shaft. According tothe bearing assembly dismounting tool, even force bearing can be achieved in the dismounting and mounting processes of a bearing, it can be ensured that the bearing is not damaged during adjusting and an adapter sleeve is not distorted during mounting and dismounting, the pre-tightening force of a pressure system can further be controlled precisely, the quality precision of mounting and dismounting of the bearing assembly can be ensured and improved to the maximum extent, and the bearing assembly dismounting tool has the advantages that potential safety hazards are eliminated, the overhaulingtime is shortened, the overhauling quality is ensured, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the field of large-scale equipment maintenance, in particular to a tool for disassembling a bearing assembly. Background technique [0002] In major industrial and mining enterprises, ports and wharves, the conveyor unit is a must-equipped device. It runs through the entire system and is the lifeline of various raw material transportation. Using belt conveyors to transport bulk materials such as iron ore can realize continuous transportation. The advantages of the iron ore port, so the productivity is high; the iron ore port is an example, the iron ore raw materials imported from abroad are unloaded, and the horizontal transportation is all adopted by the belt conveyor. The belt conveyor transportation line of more than 50,000 is responsible for the ore unloading of the entire port area , stacking, fetching, and loading transportation tasks. The conveyor belts in the port are wide and thick; and all of them are metal-lined con...

Problems solved by technology

At present, the existing maintenance process and technology, the adjustment of the disassembler of the bearing and the adapter sleeve assembly, are all carried out by maintenance personnel using self-made replacement tools and knocking with a sledgehammer. Since there is no specification requirement, it needs to be repeated Repeated blows on the lock nut to adjust; not only the work efficiency is low, but also there are many uncontrollable safety factors in the maintenance process, the quality of the components themselves and the installation cannot be guaranteed, and hidden dangers of the equipment are often buried

In the past few years, the failure time caused by the installation defects of bearing components has accounted for 15%. If the safety and smooth running cannot be guaranteed, it is difficult to improve the production efficiency.

[0004] At present, the maintenance of relevant equipment in the metallurgical mining and transportation industries is basically completed by the rough process and method of manual beating, which is not rigorous or technical at all.

At the same time, in the final stage of roller bearing assembly installation, it is necessary to monitor the clearance of the bearing to determine the tightening amount of the lock nut. The fixed sleeve fails, and axial movement occurs; similarly, due to the overfitting and overhaul of the bearing, there will be heat generation and abnormal swelling, resulting in damage to the bearing and related components.

According to the existing manual beating method, no one can fully guarantee the reliability of using spare parts, nor can it ensure the standardization of installation dimensions
