Description

Bearing positioning structure of top type medal Technical Field The utility model relates to the technical field of gyro type medals, in particular to a bearing positioning structure of a gyro type medal. Background Early medal designs focus on static aesthetic and symbolic meaning expressions, functional interaction is lost, while traditional fingertip gyroscopes have mechanical decompression properties, but are limited by single rotation function and industrial aesthetic forms, so that cultural narrative value is difficult to bear, and medal type gyroscopes are a combination of traditional medal and gyroscopic technologies, and the core technology is derived from fusion of precise bearing design, rotation dynamics optimization and medal manufacturing technology; The bearing of traditional top type medal is fixed and all adopts the mounting hole of the excircle close-fitting medal of bearing to install fixed bearing, however the assembly is too tight can lead to the rotatory smoothness of bearing to the bearing breaks out and hardly dismouting maintenance, therefore we need to propose a bearing location structure of top type medal. Disclosure of utility model The utility model aims to provide a bearing positioning structure of a top type medal, which adopts a detachable positioning component, is convenient to quickly install a bearing in an assembly hole of the medal, is convenient to detach the bearing, improves the convenience of dismounting the bearing, is convenient to maintain the bearing of the top type medal, and improves the service life of the top type medal so as to solve the problems in the background art.
