The classification and application of polishing machine gear
Composition and classification of the polishing machine gear train by two meshing gears, wherein the gear is a gear transmission in the most simple form. In the mechanical transmission, sometimes in order to obtain larger transmission ratio, or the drive shaft of a speed transformation for various rotational speed of the driven shaft, or need to change the rotary direction of the driven shaft, on the use of a series of mutually meshing gears, will drive shaft and the driven shaft is connected to form a transmission. The transmission system by "series of meshing gear called gear train.
According to transmission gear of each gear geometric axis in the relative position of the space is fixed, train can be divided into fixed axis gear train and epicyclic gear trains two categories. The main performance indexes of Jian oil viscosity, oil, flash point, pour point and pour point. Viscosity. Jian oil under the action of external force deformation resistance is called viscosity. Viscosity reflects the internal liquid produce relative motion, intermolecular friction size, Jian lubricating oil is the most important physical properties. Jian oil viscosity increases, liquidity is lower, the greater carrying capacity. Viscosity index oil stream is used to denote the viscosity. Lubrication oil viscosity with temperature and rolling bearing clearance adjustment. Rolling bearing shaft polishing equipment in the work process should have the appropriate clearance. But the clearance is too large, will enable and load bearing rolling body number reduced, caused by rolling body and the ring can generate elastic deformation and reduce the service life of the bearing. Will reduce the bearing rotation accuracy, radial runout, causing vibration and noise; clearance is too small, working resistance increases, bearing wear serious. At the same time, the resistance increases bearing easy to in the process of bearing assembly should adjust the clearance.
