introduction：The reducer is generally used for transmission equipment with low speed and high torque，Knob motor，The power of an internal combustion engine or other high-speed operation is decelerated by meshing large gears on the output shaft with fewer teeth on the input shaft of the reducer，The ordinary reducer will also have several pairs of the same principle gear to achieve the ideal deceleration effect，The ratio of the number of teeth of the big and small gears，Its the gear ratio。The reducer is a power transmission mechanism，Speed converters using gears，Slow down the rotation of the motor to the desired number of revolutions，And get a larger torque mechanism。

introduction： normal，If bearings are used correctly[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。]，Can be used until fatigue life is reached。But there will be accidental premature damage，Incapacitated for use。This early damage，Relative to fatigue life，Is a quality limit called a failure or accident。Many causes are installation、Use、lubricated

introduction：Commonly used self-sealing compression type hydraulic seals are mainly○V-sealing ring，Round sealing ring and square sealing ring, etc，They have simple structure、Easy to manufacture、Low cost and other advantages，Therefore, they are widely used in the hydraulic transmission system dynamic sealing components and static sealing components。They are usually produced when installed in a sealed tank１０—２５％The radial compression deformation，And produce higher initial contact stress on the sealing surface，This prevents the leakage of non-pressure liquid。 Hydraulic cylinder working，Pressure liquid extrusion self-sealing hydraulic seal，To further deform it，And produce a large liquid pressure with pressure on the sealing surface

introduction：Cathodic electrophoretic coating during electrophoretic coating，Work cathode，The metal surface is not dissolved，And the amine group in the resin has corrosion inhibition。Therefore, the corrosion resistance of cathodic electrophoretic coating，Much better than anodic electrophoretic coating，Even in the absence of rust-proof paint，It still has good salt spray resistance。Electrophoretic paint is applied after phosphating，Salt spray resistance achieved800h～1200h，Plus the high permeability of cathodic electrophoretic paint，Can meet the car body10No perforation corrosion protection requirements，Therefore, it is widely used in automobiles。 Electrophoretic coatings developed from anodic electrophoretic coatings to cathodic electrophoretic coatings，Also eliminate
