Disengaging method and device of anti-roll torsion bar sleeved in arm sleeve of torsion arm

Abstract

The invention discloses a disengaging method and device of an anti-roll torsion bar sleeved in an arm sleeve of a torsion arm. The disengaging method comprises the following steps: firstly, heating the arm sleeve of the torsion arm which is sleeved on the end part of the torsion bar to reach a set temperature; and quickly cooling the end part, sleeved in the arm sleeve, of the torsion bar to ensure that the end part is shrunk and loosened. The invention also discloses a disengaging device of the anti-roll torsion bar sleeved in the arm sleeve of the torsion arm. The device comprises a heater and a water injection tube, wherein a heating hole is formed in the heater; the heating hole is equipped with electric heating parts which are circumferentially arranged; when the device is used, the end part of the torsion bar is positioned in the heating hole of the heater, the arm sleeve of the torsion arm which is sleeved on the end part of the torsion bar is heated; and and when the temperature rises to the set value, water is injected into a water sprinkling hole formed in the end part of the torsion through the water injection tube. Through the disengaging method and device disclosed bythe invention, by utilizing temperature difference between expansion and contraction, the torsion arm can be easily disengaged out of the end part of the torsion arm, and damage to the torsion bar canbe avoided.

Description

technical field [0001] The invention relates to disassembly and assembly of an anti-rolling torsion bar, in particular to a method and device for removing an anti-rolling torsion bar set in a torsion arm sleeve, and belongs to the technical field of rail transportation. A method and device for pulling out an anti-roll torsion bar set in a torsion arm sleeve. Background technique [0002] For a type of straight rod type anti-rolling torsion bar on a train, the annular arm sleeves of the torsion arms at both ends are sleeved on the ends of the torsion bar by way of interference fit. When disassembly is required, the current method is to mill off the torsion arm or break the torsion bar shaft, either way, one of the parts will be damaged and cannot be further used. Contents of the invention [0003] The technical problem to be solved by the present invention is: the traditional method is difficult for the torsion arm fitted on the end of the torsion bar to escape from the en...
