High-efficiency disassembling tool for inner ring of bearing

Abstract

The invention belongs to the technical field of tool equipment, and discloses a high-efficiency disassembling tool for an inner ring of a bearing. The high-efficiency disassembling tool for the innerring of the bearing is applied to disassembling the bearing on a shaft; a gear is arranged on the shaft; the disassembling tool comprises a closed disassembling ring provided with an inner hole and formed by sequentially connecting multiple sub disassembling rings; a circumferential groove is formed at the position, installed and combined with the bearing, of the gear so as to be used for the closed disassembling ring to embed; the first end surface of the embedded closed disassembling ring fits to the end surface of the inner ring of the bearing; the second end surface of the embedded closeddisassembling ring fits to the side wall of the circumferential groove in the gear; the inner hole wall of the closed disassembling ring fits to the groove bottom of the circumferential groove; and multiple ejection mechanisms capable of being abutted against a gear web so as to enable the closed disassembling ring to drive the bearing to separate and displace along the axial direction of the shaft are uniformly distributed on the circumferential direction of the closed disassembling ring. The multiple sub disassembling rings are combined into the closed disassembling ring, the inner ring of the bearing can be easily returned to the position on which the inner ring of the bearing can be easily taken out through the ejection mechanisms abutted against the gear web so as to enable the innerring of the bearing to separate, and the tool can adapt to disassembling bearings under different conditions of various bearing installation position.

Description

Technical field [0001] The invention relates to the technical field of tooling equipment, in particular to a tool for efficiently disassembling a bearing inner ring. Background technique [0002] Bearing is an important component in the mechanical field, which is composed of inner ring, outer ring, rolling element and cage. When the bearing is not installed properly, regular maintenance and other situations, it needs to be disassembled. Since interference fit is often used between the inner ring of the bearing and the shaft parts, it is difficult to dismount the bearing when it is disassembled to ensure that the bearing is not damaged. [0003] The general methods used to disassemble the bearing are directly knocking out, heating and using tooling. Direct knocking is very easy to damage the bearing, especially when the inner ring of the bearing and the shaft have a large amount of interference, it is very difficult to knock out directly; the heating method needs to control the te...

Problems solved by technology

However, the bearing dismounting tooling in the prior art is carried by the end face of the axle, which has low disassembly efficiency, heavy tooling weight, large space occupation, and high manufacturing cost. It is more suitable for dismounting the bearing where the bearing installation position is close to the axle end face. When the location is far from the axle end face, longer connecting parts are required, and the overall axial dimension of the disassembly tool is large, heavy, and takes up a lot of space; when the distance between the bearings of different types of gearboxes and the axle end face is different, different sizes need to be made connection parts, high manufacturing cost and low versatility
