Dismantling and assembling device for large-sized bearing box

Abstract

The invention relates to a dismantling and assembling device for a large-sized bearing box, which comprises a dismantling and assembling trolley (1), a movable trolley (2) and a transfer track (3), wherein the dismantling and assembling trolley (1) comprises a lifting platform (1.1), a shift platform (1.2) and a base (1.3) which are respectively arranged horizontally, a plurality of lifting oil cylinders (1.4) are longitudinally arranged between the lifting platform (1.1) and the shift platform (1.2), the shift platform (1.2) is arranged on the base (1.3) in a sliding manner, shift oil cylinders (1.5) are laterally arranged at the left side and the right side of the base (1.3) symmetrically, and rollers (1.7) are arranged at the bottom of the base (1.3); and the movable trolley (2) comprises a rack (2.1), a track (2.2) is arranged at the top of the rack (2.1), and shifting rollers (2.3) are arranged at the bottom of the rack (2.1). The large-sized bearing box can be used for conveniently dismantling and assembling, and the dismantling and assembling device has high precision.

Description

technical field [0001] The invention relates to a device for disassembling and assembling a large bearing box, in particular to a device for disassembling and installing a large bearing box. Background technique [0002] At present, there are many ways to disassemble and assemble small bearings, and assembly techniques such as drawing, tapping, and heating are mostly used. However, due to their large size and heavy weight, during disassembly and assembly, if the protection measures are not appropriate, it is easy to cause damage to the equipment. Or personal safety accidents; small bearings are mostly assembled with transition or interference fit, while large bearings are basically assembled with clearance fit. Therefore, when disassembling large bearings, the bearing and bearing box are mostly disassembled together.

[0002] At present, there are many ways to disassemble and assemble small bearings, and assembly techniques such as drawing, tapping, and heating are mostly used. However, due to their large size and heavy weight, during disassembly and assembly, if the protection measures are not appropriate, it is easy to cause damage to the equipment. Or personal safety accidents; small bearings are mostly assembled with transition or interference fit, while large bearings are basically assembled with clearance fit. Therefore, when disassembling large bearings, the bearing and bearing box are mostly disassembled together. The disassembly and assembly of the large bearing of the bearing box from the shaft of the component is basically carried out by hoisting. During the disassembly process, due to the swing of the hoist and rigging, the hoisting object is unstable and the hoisting object Oscillation, torsion, etc., therefore, have a great impact on the alignment between the center of the bearing and the shaft and the vertical dismounting accuracy of the bearing and the shaft surface, especially during assembly, if the hoisting equipment is sent and assembled. Inaccurate center alignment can easily cause collision between the bearing and the shaft, damage or reduce the accuracy of the equipment
