introduction： Connect several basic institutions﹐In order to achieve a single mechanism is difficult to achieve the complex motion law﹑Undetachable mechanism of motion trajectory and special motion。The basic mechanism mainly includes connecting rod mechanism﹑Gear mechanism and CAM mechanism, etc。Composite mechanism is generally not a simple series of several basic mechanisms﹐Its a more complex combination﹐It can be a gear composed of different types of basic mechanisms-Connecting rod mechanism﹑CAM－Linkage mechanisms and gears-CAM mechanism﹐It can also be a linkage CAM mechanism composed of the same type of basic mechanism。The motion of the combined mechanism is based on the analysis of the motion relationship of each basic mechanism﹐Then according to

introduction： New cotton spinning equipment due to dust、Heat protection and high speed requirements，A large number of sealed bearings are used[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said，When other parts move relative to each other on the shaft，A device used to reduce the coefficient of friction during power transmission and to keep the center of the shaft fixed。]。These bearings run after a certain period，Because of lack of oil inside，The bearing is damaged by dry grinding。For example, the bearing is sealed on the inlet air spinning machine，numerous、Good material，But after years of use，ina-nota
