Embodiment 1

[0029] Embodiment one, see figure 1 , a torque converter turbine oil seal installation tool with a holding rod for automatic transmission remanufacturing, comprising a push rod 1. The right end of the push rod 1 is provided with a grip bar 6 . 6 sets of grip bars are provided with handle gloves 61 . The handle glove 61 is a rubber sheath. The left end of the push rod 1 is provided with a column head 11 , a first protruding ring 12 and a second protruding ring 13 in sequence. The oil seal 2 includes an oil seal main body 21 and an annular sealing lip 22 . The sealing lip 22 is arranged on the radially outer side of the end surface of the oil seal main body 21 .

[0030] The diameter D1 of the column head is smaller than the inner diameter D2 of the main body of the oil seal. The length L1 of the column head is greater than or equal to the axial length L2 of the main body of the oil seal. The outer diameter D3 of the first collar is smaller than the inner diameter D4 of th...

Embodiment 2

[0035] Embodiment two, the difference with embodiment one is;

[0036] 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 entrance and exit passage 921 passes through the annular groove 14 on the first protrusion ring 12 . The entrance and exit passage 921 is provided with an annular cylinder 924 extending along the circumference of the column head 11 . The annular cylinder body 924 is sealed and slidably connected wi...

Abstract

The invention relates to the technical field of remanufacturing of an automatic gearbox, in particular to a torque converter turbine oil seal mounting tool with a holding rod for remanufacturing of the automatic gearbox. The torque converter turbine oil seal mounting tool comprises a push rod; an oil seal comprises an oil seal body and an annular sealing lip arranged on the radial outer side of the end face of the oil seal body; a column head, a first convex ring and a second convex ring are sequentially arranged at one end of the push rod; the diameter of the column head is smaller than the inner diameter of the oil seal body; the length of the column head is larger than or equal to the axial length of the oil seal body; the outer diameter of the first convex ring is smaller than the inner diameter of the sealing lip; the axial length of the first convex ring is equal to the axial length of the sealing lip; the outer diameter of the second convex ring is larger than the inner diameter of the sealing lip and smaller than or equal to the outer diameter of the sealing lip; and the holding rod is arranged at the other end of the push rod. The torque converter turbine oil seal mounting tool with the holding rod for remanufacturing of the automatic gear box can mount the oil seal with the sealing lip into a hydraulic torque converter turbine conveniently and the problem that the oil seal of the hydraulic torque converter turbine is inconvenient to mount 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 torque converter turbine oil seal installation tool with a grip bar for remanufacturing of automatic transmissions. Background technique [0002] The hydraulic torque converter is a part of the automatic transmission. The hydraulic torque converter is provided with a turbine, and the turbine is provided with an oil seal. The oil seal includes an oil seal main body and an annular sealing lip arranged radially outside the end face of the oil seal main body. Oil seals are installed in torque converter turbines during automatic transmission rebuilds. The existing way to install the turbine oil seal of the torque converter is to align the oil seal with the hole in the turbine by hand, and then press or tap the oil seal with a hammer to install the oil seal. The existence of the seal makes it very inconvenient to install, and it is easy to cause lo...
