Embodiment 1

[0031] Embodiment one, see figure 1 , a main oil seal installation tool provided with a holding rod for automatic transmission remanufacturing, including a push rod 1. The end surface of the main oil seal 2 is provided with an annular groove 21 extending axially along the main oil seal. The outer side wall of the annular groove 21 forms an outer sealing lip 22 . A limit ring 11 extending along the circumferential direction of the push rod is provided on the outer peripheral surface of the push rod 1 . The outer diameter D1 of the limiting ring is larger than the outer diameter D2 of the main oil seal. A protruding ring 12 is provided on the left end surface of the limiting ring 11 . The outer diameter D3 of the protruding ring is less than or equal to the outer diameter D2 of the main oil seal, and the difference between the outer diameter D2 of the main oil seal and the outer diameter D3 of the protruding ring is less than 0.2 mm. The left end of the push rod 1 is provide...

Embodiment 2

[0037] Embodiment two, the difference with embodiment one is;

[0038] see Figure 4 , The push rod 1 is also provided with an oil seal dismounting booster mechanism 9. The oil seal detachment assisting mechanism 9 includes a fan 91 , an air duct 92 and an air direction conversion mechanism 93 . The fan 91 is provided with an air inlet 911 and an air outlet 912 . The fan 91 includes fan blades 913 and a motor 914 for driving the fan blades. The air duct 92 is an annular structure. The air duct 92 communicates with the air inlet 911 and the air outlet 912 . The air duct 92 is provided with an entrance and exit passage 921 , an entrance passage 922 and an exit passage 923 . The access road 921 runs through to the push ring 14 . The entrance and exit passage 921 is provided with an annular cylinder 924 extending circumferentially along the push ring 14 . The annular cylinder body 924 is sealed and slidably connected with an annular thimble driving piston 925 . The thimble...

Abstract

The invention relates to the technical field of remanufacturing of an automatic gearbox, in particular to a main oil seal mounting tool with a holding rod for remanufacturing of the automatic gearbox. The end face of a main oil seal is provided with an annular groove, and an outer sealing lip is formed on the outer side wall of the annular groove. The main oil seal mounting tool with the holding rod for remanufacturing of the automatic gearbox is characterized in that the tool comprises a push rod; a limiting ring is formed in the outer peripheral face of the push rod; the outer diameter of the limiting ring is larger than the outer diameter of the main oil seal; one end of the push rod is provided with a receding hole and a push ring; the diameter of the receding hole is larger than the inner diameter of the main oil seal; the inner diameter of the push ring is larger than the inner diameter of the annular groove; the diameter of the push ring is smaller than the outer diameter of the annular groove; and the holding rod is arranged at the other end of the push rod. The main oil seal mounting tool with the holding rod for remanufacturing of the automatic gearbox can mount the main oil seal conveniently and accurately, and the problem that the main oil seal is inconvenient to mount and not likely to be mounted in place accurately in the remanufacturing process of the automatic gearbox is solved.

Description

technical field [0001] The invention relates to the technical field of remanufacturing of automatic transmissions, in particular to a main oil seal installation tool provided with a grip bar for remanufacturing of automatic transmissions. Background technique [0002] During the reconstruction process of the automatic transmission, the main oil seal needs to be installed on the corresponding installation hole of the transmission and at the same time be sleeved on the rotating shaft. The end face of the main oil seal is provided with an annular groove, and the outer wall of the annular groove forms the outer sealing lip. The existing method of installing the main oil seal is to align the oil seal with the main oil seal hole of the transmission by hand, and then press or tap the main oil seal with a hammer to install the main oil seal. This method is very inconvenient to install and the oil seal is difficult to install accurately To the required depth, and it is easy to hit th...
