Description

Oil seal seat assembly, engine and vehicle

Technical Field

The utility model relates to the field of engines, in particular to an oil seal seat assembly, an engine and a vehicle.

Background

Oil seals are important parts of engine seals, and the assembly mode and requirements of the oil seals are more and more important. The first assembly mode is that the oil seal is directly pressed into an oil seal mounting hole so as to be directly assembled on an engine; the second assembly method is to assemble the oil seal to the oil seal seat first and then assemble the oil seal seat to the engine. Compared with the first assembly mode, the second assembly mode of the oil seal is applied when the structural space is limited or special purposes are achieved.

In the second assembly method, when the oil seal seat is assembled on the engine, the structure of the positioning pin and the sealant is needed to realize the sealing effect. The coaxiality of the oil seal and the engine crankshaft is controlled through the positioning pin, and the phenomenon that the axle center deviation of the oil seal and the engine crankshaft is too large, so that the sealing failure of the oil seal is caused is prevented. Secondly, a sealant is coated on the oil seal seat to seal the engine oil between the engine crankshaft and the oil seal seat, so that the sealing purpose is realized. However, when the sealant is coated, the surface to be coated of the part needs to be manually removed with grease, and the coating thickness of the sealant is difficult to ensure the consistency; meanwhile, the application of the sealant requires application equipment, and the investment is large.

The foregoing description is provided for general background information and is not admitted to be prior art.
