Structure capable of easily disassembling bearing

Abstract

The utility model relates to the field of bearing disassembly, in particular to a structure capable of easily disassembling a bearing. Comprising bearing seats and bearings, a bearing hole is formed in the bearing seat, a small hole is formed in the edge of the bearing hole, a pulling block is placed in the small hole, a clamping edge is arranged at one end, extending into the bearing seat, of the pulling block, the clamping edge is buried below a bearing, the other end of the pulling block extends out of the bearing hole, a threaded hole is formed in the outer end face of the pulling block, and the threaded hole is connected with the pulling block. According to the working principle and the working process of the bearing disassembling device, the bearing can be disassembled easily by embedding the pulling block for pulling the bearing below the bearing and sleeving the pulling tool into the threaded hole through the pulling tool which can be purchased on the market or self-made.

Description

Technical Field

[0001] The utility model relates to the field of bearing disassembly, in particular to a structure for easily disassembling a bearing. Background Art

[0002] At present, the main shaft speed of the machine is very high. The bearings that support the main shaft are wearing parts and need to be replaced regularly. The removal of the bearings requires auxiliary electric welding or fire cutting, and the bearings are taken out by hammering or beating, which affects the accuracy of the main shaft and the bearing seat, increases the vibration of the machine, and shortens its life. Summary of the invention

[0003] The utility model aims to provide a structure for easily disassembling a bearing. A puller block for lifting the bearing is pre-buried under the bearing, and the bearing can be easily disassembled by a puller.

[0004] The technical solution of the utility model is: a structure for easily disassembling bearings, comprising a bearing seat and a bearing; a bearing hole is opened on the bearing seat, a small hole is arranged on the edge of the bearing hole, a pull block is placed in the small hole, one end of the pull block extending into the interior of the bearing seat is provided with a clamping edge, the clamping edge is buried under the bearing, the other end of the pull block extends out of the bearing hole, and a threaded hole is opened on the outer end surface of the pull block.

[0005] The utility model has the beneficial effect that the bearing can be easily disassembled by using a puller through pre-embedded puller blocks for pulling out the bearing under the bearing. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0012] As shown in the figure, a structure for easily disassembling bearings comprises a bearing seat 1 and a bearing 2; a bearing hole 3 is formed on the bearing seat 1, a small hole 4 is formed on the edge of the bearing hole 3, a pull block 5 is placed on the small hole 4, and a clamping edge 51 is formed on one end of the pull block 5 extending into the interior of the bearing seat 1, and the clamping edge 51 is buried under the bearing 2, and the other end of the pull block 5 extends out of the bearing hole 3, and a threaded hole 52 is formed on the outer end surface of the pull block 5.

[0013] In summary, the working principle and working process of the utility model are as follows: a bearing extraction block 5 is pre-buried under the bearing 2, and a commercially available or homemade extraction tool is inserted into the threaded hole 52, so that the bearing can be easily removed.

[0014] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
