Oil seal protective tooling of the present utility model, comprise tile 1 and lower tile 2, and the outer surface of the outer surface of upper tile 1 and lower tile 2 is oil sealing mating surface.As shown in Figure 1, before driving shaft 5 is installed, the outer surface of the outer surface of upper tile 1 and lower tile 2 is coordinated with the inner surface of oil sealing 4 respectively, can protect oil sealing 4; After driving shaft 5 installations; directly take off respectively tile 1 and lower tile 2; and need not make tile 1 and lower tile 2 produce distortion; and then reduced preferably this oil seal protective tooling because of the impaired possibility of distortion, thereby the service life of effectively having improved this oil seal protective tooling.
Further, upper tile 1 can be the different semicircle annular tile of radius with lower tile 2, and upper tile 1 can be also the identical semicircle tile of radius with lower tile 2, can more easily process above-mentioned two tiles.
Particularly, the outer surface of the outer surface of upper tile 1 and lower tile 2 can have one at least for arc-shaped surface, the certainly upper outer surface of tile 1 and the outer surface of lower tile 2 can be also the curved surface of other shapes, yet the curved surface of other shapes may cause damage to the inner surface of oil sealing 4 after contacting with oil sealing inner surface when mounted, in order to reduce the damage to oil sealing inner surface, can preferably go up the outer surface of tile 1 and the outer surface of lower tile 2 is arc-shaped surface, coordinating with the inner surface of oil sealing 4 preferably, also can guarantee preferably that this oil seal protective tooling can not cause damage to the inner surface of oil sealing 4.
Particularly, the radius of the outer surface of upper tile 1 can be less than oil sealing radius, and the radius of the outer surface of lower tile 2 also can be less than oil sealing radius, and the space of now going up between tile 1 and lower tile 2 is less, can not more easily assemble driving shaft 5.The radius of the outer surface of upper tile 1 can be greater than oil sealing radius, and the radius of the outer surface of lower tile 2 also can be greater than oil sealing radius, all can make this oil seal protective tooling deform, thereby affect its service life during now due to each use.
