Abstract

The invention discloses a bearing detachment device. The bearing detachment device comprises a base used for abutting and clamping bearings and driving the bearings to move, and a traction mechanism connected with the base, wherein the base comprises alignment mandrels used for abutting and clamping the bearings and uniformly distributed in the circumferential direction, the alignment mandrels are connected with a first screw rod used for pushing the alignment mandrels to move to adapt to clamp the bearings with different dimensions, and the first screw rod is screwed onto the base; and the traction mechanism is connected with a rotation mechanism through a thread, and the rotation mechanism drives the traction mechanism to move through the reaction of the thread. The bearing detachment device is applicable to detachment for the separable angular contact bearings, and capable of meeting the detachment need of the bearings with different types and dimensions through adjusting the dimensions of the base; the stress equilibrium of the bearings is guaranteed, detachment traces left due to partial overload are avoided, and a main shaft is prevented from scratches; and the bearing detachment device can be used for the bearings next to mating parts and is capable of avoiding detachment traces left on the adjacent mating parts.

Description

technical field [0001] The invention relates to the field of bearing assembly, in particular to a bearing dismounting device. Background technique [0002] Bearings are widely used in automobiles, ships, aviation and other fields, including high-speed rotary bodies in these fields, and high-speed rotary bodies have strict requirements on the interference fit of bearings. At this time, the inner ring of the bearing must play a fixed role , and it is necessary to facilitate disassembly during the assembly and debugging process, which has higher requirements for bearing disassembly tools. The aero-engine needs to perform a dynamic balance test on the main shaft of the blade before the test run. This process requires multiple bearing disassembly on the main shaft, but the strict interference fit makes it difficult to disassemble the bearing, and it is easy to scratch the mating parts during the disassembly process. Main shaft; In addition, the size of the force-bearing part tha...
