Abstract

The invention discloses a mobile rolling bearing pressing and withdrawing machine and belongs to the technical field of railway equipment manufacturing. The mobile rolling bearing pressing and withdrawing machine comprises a press fitting device, a withdrawing device, a lifting adjustment device and a trolley. The trolley is used as a working platform, so that the mobile rolling bearing pressing and withdrawing machine cannot be limited by sites and track gauges. The mobile rolling bearing pressing and withdrawing machine realizes press fitting and withdrawing for a bearing through a dual extruding rod type hydraulic cylinder and has the advantages of being simple in structure, convenient to operate and safe and reliable, the labor intensity of staff is reduced, and the usage cost is low. Longitudinal position regulation is realized through fore and aft movement of the trolley, transverse regulation is realized through movement of a lifting device moving seat on a linear guide rail, and height regulation is realized through a lifting cylinder, so that the dual extruding rod type hydraulic cylinder and the bearing are uniformly stressed. The dual extruding rod type hydraulic cylinder is in a semi-floating state in a vertical direction through a spring hanger on a lifting device, the unparallel influence among a rail surface, a center line of a wheel shaft and a linear guide rail can be eliminated, and the pressing and withdrawing quality of the bearing is ensured.

Description

technical field [0001] The invention relates to a mobile rolling bearing pressing machine, which belongs to the technical field of railway equipment manufacturing. Background technique [0002] For a long time, the bearing press-fitting and unloading machinery used on railway rail transit wheel sets are basically completed by different equipment. It is because these devices have a large number and occupy a large area, and cannot adapt to the maintenance of wheel sets of self-owned vehicles with few operating mileages. In particular, some countries have less railway mileage and fewer railway vehicle maintenance equipment, and some simple equipment are needed to complete the bearing pressing and unloading machinery on the wheel set. Solve the problem that the bearing press-fitting and unloading machinery has a large volume and high cost, and its use is limited by site space conditions. Contents of the invention [0003] The present invention just aims at the deficiencies o...
