Abstract

The utility model provides a torque-limiting type fluid coupling ware dismantles specialized tool, mechanical equipment maintains and overhauls instrument, it includes that a length is 500 mm's round bar, the right-hand member of round bar is equipped with length and is 20mm, the diameter is 35.7mm be used for with motor shaft complex cooperation end, the left end of round bar is equipped with the square spacing end that the length of side is 50mm, spacing end radially is equipped with the through-hole that the diameter is 30mm, spacing end is equipped with length on one side and is 230mm, the diameter is 42 mm's polished rod, it is 200mm to be equipped with length between polished rod and the cooperation end, the diameter is 42 mm's threaded rod. When the torque-limiting hydraulic coupler and the working machine are pulled out, the jackscrew is screwed in from the output end of the hydraulic coupler. The handle is inserted into the inner hole at the tail part of the screw rod to screw the screw, and the rotating torque force is converted into a force pressing forwards by the screw thread, so that the motor shaft is ejected out of the hole of the hydraulic coupler step by step, the safety risk of object striking in the operation process is eliminated, and the labor intensity of workers is reduced.

Description

Special tool for disassembling torque-limiting hydraulic coupler

Technical Field

The invention relates to a special tool for disassembling a torque-limiting type hydraulic coupler, and belongs to the field of maintenance and overhaul of mechanical equipment.

Background

A fluid coupling is a fluid transmission device used to connect a power source (usually an engine or an electric motor) to a working machine and transmit torque by a change in fluid momentum torque. According to different purposes, the hydraulic couplers are divided into a common hydraulic coupler, a torque-limiting hydraulic coupler and a speed-regulating hydraulic coupler. When the torque-limiting hydraulic coupler and the matched motor and speed reducer are overhauled and maintained, because the shaft hole at the input end of the hydraulic coupler is tightly matched with the motor shaft, and the hydraulic coupler generates temperature in operation, after the torque-limiting hydraulic coupler and the matched motor and speed reducer work for a period of time, the shaft and the shaft hole generate interference fit. When the hydraulic coupler is connected with the motor, the difficulty is high, and the common drawing device is difficult to use. Meanwhile, as the hydraulic coupler is made of aluminum, the hydraulic coupler is easy to damage and cannot be used if being knocked by external force in the pulling and unloading process.

Disclosure of Invention

In order to solve the problems that a hydraulic coupler is difficult to disassemble and is easy to damage after being disassembled forcefully, the invention provides a special tool for disassembling a torque-limiting type hydraulic coupler, which can completely and quickly disassemble the torque-limiting type hydraulic coupler in the overhauling process of the torque-limiting type hydraulic coupler, a matched motor and a speed reducer, reduce the safety risk in the operation process and simultaneously avoid the damage of the torque-limiting type hydraulic coupler.

The utility model provides a specialized tool is dismantled to limit square hydraulic coupler, be 500 mm's round bar including a length, the right-hand member of round bar is equipped with length and is 20mm, the diameter is 35.7mm be used for with motor shaft complex cooperation end, the left end of round bar is equipped with the square spacing end that the length of side is 50mm, spacing end radially is equipped with the through-hole that the diameter is 30mm, spacing end is equipped with length on one side and is 230mm, the diameter is 42 mm's polished rod, it is 200mm to be equipped with length between polished rod and the cooperation end, the diameter is 42 mm's threaded rod.

When the torque-limiting hydraulic coupler and the working machine are pulled out, the jackscrew is screwed in from the output end of the hydraulic coupler. The handle rod is inserted into the through hole of the limiting end, the handle is rotated to drive the round rod to rotate, the rotating torque is converted into a force which is pressed forwards by the threads, and therefore the motor shaft is ejected out of the hydraulic coupler hole step by step.

The hydraulic coupler can be disassembled by using the hydraulic coupler disassembling tool without manufacturing special pulling discs and pulling tools and knocking and striking the hydraulic coupler by using a sledge hammer, so that the safety risk of striking objects in the operation process is eliminated, the labor intensity of workers is reduced, the working efficiency is high, the hydraulic coupler disassembling tool can be completed in 2 hours, and the overhauling time is saved by 4 hours (6 hours are needed before the hydraulic coupler is disassembled without using the hydraulic coupler disassembling tool). Meanwhile, due to the safety of the disassembly mode, the safety risk in the operation process is reduced, and the damage of the hydraulic coupler is avoided.
