Embodiment Construction

[0028] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0029] Such as Figure 2-6 As shown, the embodiment of the present invention provides an installation tool for the crankshaft rear oil seal. The installation tool is used for press-fitting the crankshaft rear oil seal. The main body 11 can adopt a columnar structure, one end of which is the hitting end, and the other end is equipped with a driving disc 12, a guide disc 13 and an oil sealing block 14.

[0030] The drive disc 12 is rotatably mounted on the main body 11, and its rotation direction is perpendicular to the pressing direction of the rear oil seal of the crankshaft. The end face of the drive disc 12 has helical teeth. The guide plate 13 is mounted on the body 11 and has a plurality of guide grooves thereon. There are multiple oil seal...

Abstract

The invention discloses an installing tool for a rear oil seal of a crankshaft. The installing tool comprises a body, a driving disk rotationally installed on the body, a guiding disk installed on the body and a plurality of oil seal acting blocks installed on the guiding disk in a sliding manner. The end face of the driving disk is provided with spiral teeth. The oil seal acting blocks are provided with tooth faces opposite to the spiral teeth. The tooth faces are provided with driving teeth meshed with the spiral teeth. The oil seal acting blocks have sliding strokes during which the oil seal acting blocks get close to or away from one another under the action of cooperation of the driving teeth and the spiral teeth. According to the installing tool, the positions of the oil seal acting blocks on the guiding disk are adjusted through the spiral teeth, and therefore the installing tool is suitable for rear oil seals in different sizes. Thus, the universality of the installing tool is better.

Description

technical field [0001] The invention relates to the technical field of engine installation, in particular to an installation tool for a crankshaft rear oil seal. Background technique [0002] The crankshaft rear oil seal is one of the important parts in the engine, and the crankshaft rear oil seal is usually installed on the engine by pressing. [0003] Such as figure 1 As shown, the tool used for press-fitting the rear oil seal of the crankshaft in the traditional technology includes an oil seal action end and a striking end, and the oil seal action end can be in contact with the surface of the crankshaft rear oil seal. When it is necessary to press install the crankshaft rear oil seal, attach the oil seal working end to the crankshaft rear oil seal, and then tap the striking end. location. [0004] However, the oil seal function end of the above tool needs to adjust its own size according to the size of the crankshaft rear oil seal. Therefore, in the actual application ...
