[0002] The skeleton oil seal is a typical representative of oil seals. Generally speaking, the oil seal refers to the skeleton oil seal. The function of the oil seal is generally to isolate the parts of the transmission components that need lubrication from the external environment to prevent the lubricating oil from leaking. The skeleton is like the steel bar in the concrete component, which plays a reinforcing role and enables the oil seal to maintain its shape and tension. According to the structural form, it can be divided into single-lip skeleton oil seals and double-lip skeleton oil seals. The auxiliary lip of the double-lip skeleton oil seal plays a dust-proof role, preventing external dust and impurities from entering the machine. According to the skeleton type, it can be divided into inner skeleton oil seals, exposed skeleton oil seals and assembled oil seals. According to the working conditions, it can be divided into rotating skeleton oil seals and reciprocating skeleton oil seals. It is used in gasoline engine crankshafts, diesel engine crankshafts, gearboxes, differentials, shock absorbers, engines, axles and other parts.

At this time, it seems that the oil seal body 1 is adsorbed on the bottom of the gland 2. The oil seal body 1 is aligned with the oil seal groove of the installation part by holding the positioning plate 14, and then the second rotating block 20 is rotated to make the clamping block 19 close to the bottom end of the installation part. At this time, the second screw rod 18 is close to the side of the installation part, which is equivalent to four groups of second screw rods 18 clamping the installation part, and the clamping block 19 is against the bottom of the installation part. At this time, the first rotating block 13 can be rotated to The first screw rod 11 is moved downward along the positioning plate 14, and the pressure cover 2 is simultaneously moved downward to squeeze the oil seal body 1. The oil seal body 1 can be stably installed in the oil seal groove through the squeezing of the pressure cover 2.
