Abstract
The utility model relates to a puller structure for demounting an automotive transmission and belongs to the technical field of assembly of the automotive transmission. The technical scheme is that the puller structure comprises a bolt (1), a sleeve (2), a connection piece (3), pull claws (4), a first pin shaft (5), a first split pin (6), a second pin shaft (7) and a second split bin (8). The bolt (1) penetrates through the sleeve (2) and is in threaded connection with the sleeve (2), three pull claws (4) are evenly arranged at the end of the sleeve (2) in the peripheral direction, are in shaft connection with one end of the connection piece (3) through the first pin shaft (5) and are fixed through the first split pin (6), and the other end of the connection piece (3) is in shaft connection with the sleeve (2) through the second pin shaft (7) and is fixed through the second split bin (8). Parts of bearings, catch wheels, synchronizer gear hubs and the like in the transmission can be demounted conveniently and quickly, labor intensity is reduced, reliability is improved, and the puller structure solves the problems which cannot be solved by conventional pullers.
Description
Technical field
The utility model relates to a kind of automotive transmission dismounting with drawing horse structure, belongs to automotive transmission mounting technology field.
Background technology
Speed changer assembling is one of link for speed changer manufacturing most critical, and can it normally bring into play function to speed changer and play decisive role in car load.And will repair for in-problem speed changer after handing over inspection, so just need to use corresponding disassembling fixture.At present, when dismounting automobile speed variator bearing, gear wheel and synchromesh gear hub, if while being subject to the limitation of size or shape cannot use a pile son to dismantle, often adopt flat chisel cutter, be easy to like this other assembly near demolition part to damage, reliability does not guarantee, labour intensity is large.
Utility model content
The utility model object is to provide a kind of automotive transmission dismounting with drawing horse structure, can complete very easily the dismounting of the parts such as speed changer middle (center) bearing, gear wheel and synchromesh gear hub, improves reliability, solves the problem existing in background technology.
The technical solution of the utility model is:
A kind of automotive transmission dismounting is with drawing horse structure, comprise bolt, sleeve, brace, pulling claw, bearing pin one, split pin one, bearing pin two and split pin two, bolt is through sleeve, and be connected with bush whorl, sleeve ends along the circumferential direction evenly arranges three pulling claws, and pulling claw is connected with one end axle of brace by bearing pin one, and fixing by split pin one, the other end of brace is connected with quill by bearing pin two, and fixing by split pin two.
The tip shaped of described bolt.
Adopt the utility model, when dismounting automobile speed variator bearing, first the top part of bolt pushed to sleeve, then three pulling claws are caught on to bearing outer ring, then by the top center hole that heads into of bolt, finally by aerodynamic moment spanner by bolt tightening until bearing is pulled out.Equally, adopt the utility model, also can complete the dismounting of the parts such as automotive transmission gear wheel and synchromesh gear hub.
The beneficial effects of the utility model are: complete easily, efficiently the dismounting of the parts such as speed changer middle (center) bearing, gear wheel and synchromesh gear hub, reduce labour intensity, improve reliability, solved conventional pile sub insurmountable problem.
Accompanying drawing explanation
Fig. 1 is that the utility model is used state front view;
Fig. 2 is the utility model side view;
In figure: bolt 1, sleeve 2, brace 3, pulling claw 4, bearing pin 1, split pin 1, bearing pin 27, split pin 28.
The specific embodiment
Below in conjunction with accompanying drawing, by example, the utility model is described in further detail.
With reference to accompanying drawing 1, 2, a kind of automotive transmission dismounting is with drawing horse structure, comprise bolt 1, sleeve 2, brace 3, pulling claw 4, bearing pin 1, split pin 1, bearing pin 27 and split pin 28, the tip shaped of bolt 1, bolt 1 is through sleeve 2, and be threaded with sleeve 2, sleeve 2 ends along the circumferential direction evenly arrange three pulling claws 4, pulling claw 4 is connected with one end axle of brace 3 by bearing pin 1, and fixing by split pin 1, the other end of brace 3 is connected with sleeve 2 axles by bearing pin 27, and fixing by split pin 28, three pulling claws rotate freely.
With reference to accompanying drawing 1, when dismounting automobile speed variator bearing, first the top part of bolt 1 is pushed to sleeve 2, again three pulling claws are caught on to bearing outer ring, three pulling claws catch on to guarantee as far as possible after bearing outer ring pulling claw be subject to force direction with by pulling shaft, held axial consistent, only in this way guarantee draws horse work time not break off relations, then by the top center hole that heads into of bolt 1, finally by aerodynamic moment spanner by bolt tightening until bearing is pulled out.Equally, adopt the utility model, also can complete the dismounting of the parts such as automotive transmission gear wheel and synchromesh gear hub.
Claims (2)
1. an automotive transmission dismounting is with drawing horse structure, it is characterized in that comprising bolt (1), sleeve (2), brace (3), pulling claw (4), bearing pin one (5), split pin one (6), bearing pin two (7) and split pin two (8), bolt (1) is through sleeve (2), and be threaded with sleeve (2), sleeve (2) end along the circumferential direction evenly arranges three pulling claws (4), pulling claw (4) is connected with one end axle of brace (3) by bearing pin one (5), and fixing by split pin one (6), the other end of brace (3) is connected with sleeve (2) axle by bearing pin two (7), and fixing by split pin two (8).
2. automotive transmission dismounting according to claim 1, with drawing horse structure, is characterized in that the tip shaped of described bolt (1).
