Motor end cover, bearing and coupling motor wheel pulling combined tool

Abstract

The invention discloses a motor end cover, bearing and coupling motor wheel pulling combined tool. The tool mainly solves the problem that no unified tool exists for assembling and disassembling a motor end cover, a motor bearing and a coupling motor wheel in the prior art. The tool is characterized in that the center of the left side of a main body (2) is in threaded connection with an ejector rod (1); three tension lead screws (3) evenly distributed in the circumferential direction are connected to the outer side of the main body (2), a bracket (4) with a semicircular section is fixed to theedge of the side, opposite to the ejector rod (1), of the main body (2), a righting pipe (5) is fixed to the end of the bracket (4), and bearing backup plates (6) are connected to the ends of the three tension lead screws (3) and are rings with one end opened. The motor end cover, bearing and coupling motor wheel pulling combined tool is convenient to carry, simple to operate, wide in applicationrange and capable of improving the working efficiency.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a combined tool for extracting motor end covers, bearings, coupling motor wheels. Background technique [0002] At present, the disassembly and assembly of the motor end cover of the pumping unit basically adopts the method of prying and smashing, which is easy to damage the motor and the end cover. Motor bearings are basically smashed in by heating bearings or thick-walled long tubes, and it is very difficult to take them out. The existing special tools for removing bearings are basically not suitable for large motors in oil fields. It is necessary to use an angle grinder to cut the bearings or take out the bearings by heating, which is easy to damage the motor coils and other components and is risky. The motor shaft of the transfer station is relatively long and straight, and the installation and disassembly of the coupling motor wheel is very difficult. At present, a puller is used t...

Problems solved by technology

Motor bearings are basically smashed in by heating bearings or thick-walled long tubes, and it is very difficult to take them out

The existing special tools for removing bearings are basically not suitable for large motors in oil fields. It is necessary to use an angle grinder to cut the bearings or take out the bearings by heating, which is easy to damage the motor coil and even other components and is risky

The motor shaft of the transfer station is relatively long and straight, and the installation and disassembly of the coupling motor wheel is very difficult. At present, a puller is used to pull out a copper rod, and auxiliary tools are required. The labor intensity is high, the operation risk is high, and the motor is easily damaged. wheel

As mentioned above, at present, there is no uniform tool for disassembling and assembling the motor end cover, motor bearing, and coupling motor wheel. The existing tools have single functions and are not strong in combination, resulting in increased maintenance costs and low work efficiency.
