The invention discloses a special device for maintenance and installation of an oil seal of a crankshaft of a heavy-duty engine. The device comprises an engine shell, the crankshaft, the oil seal, anoil seal positioning push sleeve, a turbine, a rear cover and bolts, wherein the front end of the oil seal positioning push sleeve is matched with the oil seal and presses the oil seal, and sleeve positioning holes through which the bolts pass are arranged in the bottom of the rear end of the oil seal positioning push sleeve; the turbine is matched with the oil seal positioning push sleeve througha threaded structure; a worm is arranged on the rear cover and is in transmission connection with the turbine, and rear cover positioning holes through which the bolts pass are arranged in the bottomof the rear end of the rear cover; and the bolts sequentially penetrate through the rear cover, the turbine, the oil seal positioning push sleeve and the oil seal, and are fixed to a journal of the crankshaft. The device is small and portable, easy to carry, easy and convenient to operate and high in efficiency, not only can be used when the engine is repaired, but also can be used for on-vehicleemergency in a maintenance site, fewer accessory are disassembled during on-vehicle maintenance, and the maintenance speed can be effectively improved.
Description
technical field [0001] The invention relates to the technical field of tools for installing engine equipment, in particular to a special device for maintenance and installation of heavy-duty engine crankshaft oil seals. Background technique [0002] The crankshaft is one of the important parts of the automobile engine. It converts the gas pressure transmitted by the piston connecting rod into torque to drive the transmission system of the automobile, the valve mechanism of the engine and other devices. The oil seal of the crankshaft of the engine is a skeleton type oil seal, which is composed of a metal skeleton ring and a rubber sealing layer (ring). ) to control the oil film, limit the leakage of lubricating oil in the engine, and prevent sediment, dust, and water vapor from invading the engine from the outside. [0003] Now to install the crankshaft oil seal of the engine, the positioning sleeve is positioned in the radial direction of the crankshaft, and the slide hamme...
