This differential principle differential adjustment is automatic, involved here, "the principle of minimum" differential gear manufacturers, i.e. all objects on the earth tends to a minimum energy state. Such as the grain of beans into a bowl, beans and never will automatically stay stuck in the wall of the bowl, because the bowl is the lowest energy position (potential energy) in the bowl, it automatically selects the static (kinetic energy minimum) without will be in constant motion. By the same token differential gear cutting, 3D effects will automatically turn the wheel at the time of the state of lowest energy consumption trends, according to the turning radius automatically adjust the speed of the left and right wheels. Luoyang Fuyuan various gears Gear Machinery Co., Ltd. specializes in producing bevel gears, shafts, plates, etc., please come to order. Maintenance of a differential. Differential case can not have any contact with the nature of crack, and the planetary gear housing gasket between the differential side gears should be smooth and free of grooves; if minor groove or worn, can continue to be used after grinding differential gear, or should be replaced or repaired. 2. A planetary gear differential case and the planetary gear axle shaft hole with the gap shall not exceed 0.1-0.15mm, with the side gears journal and shell hole clearance fit, there should be no significant Songkuang feeling, or should be replaced or repaired .
