Beneficial effect
The utility model compared with prior art, has the advantage that are as follows:
1, bearing inner race is caught on by two drag hooks, reuses hydraulic device tensile ties and disposably pulls out bearing, grasped
Make it is simple, high-efficient, than conventional method save 25 seconds/time；
2, it in disassembly bearing overall process without being beaten to components, the case where avoiding bearing unilateral stress, does not deposit
In the hidden danger of components of damaging, flywheel mass can guarantee, effectively prevent the case where scrapping components generation occur, directly reduce
Rework cost.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Wherein: 1- balance plate, 2- pull rod, 3- drag hook, 31- straight connecting rod, 32- hook portion, 33- idler wheel, the first spring of 4-, 5- stop
Push plate, 6- second spring, 7- locking member, 8- positive stop lug boss, 9- limited block, H- protrusion height.
Specific embodiment
Specific embodiment in reference to the accompanying drawing is described further the utility model.
Refering to fig. 1, a kind of flywheel bearing disassembling fixture, including balance plate 1, being equipped at the top of balance plate 1 can be with hydraulic device
The pull rod 2 of connection, 1 bottom of balance plate are set there are two the drag hook 3 being hinged and connected with balance plate 1, and two drag hooks 3 are with the axis of pull rod 2
Heart line is symmetrically arranged in the both ends of balance plate 1, and drag hook 3 includes the straight connecting rod 31 hinged with balance plate 1, is located at 31 lower end of straight connecting rod
And extend outward for catching on the hook portion 32 of bearing inner race, be equipped with the first bullet for holding out against the two between two straight connecting rods 31
Spring 4 makes two hook portions 32 that can catch on bearing inner race always under the elastic force of the first spring 4, can be applicable in disassembly sizes
Bearing.
Angle between hook portion 32 and straight connecting rod 31 is acute angle, can make hook portion 32 that can only connect with bearing inner race, raising is torn open
Job stability is unloaded, is integrally formed structures between hook portion 32 and straight connecting rod 31, great work intensity is simple to manufacture.
32 one end of hook portion is equipped with the idler wheel 33 that can be connected with flywheel bearing hole wall for protruding from hook portion 32, in idler wheel 33
Embedded in 32 one end of hook portion, the protrusion height H that idler wheel 33 protrudes from hook portion 32 is less than the thickness of bearing inner race, in disassembly process,
Idler wheel 33 is contacted with flywheel bearing hole wall always, and hook portion 32 is contacted with bearing inner race, can be to avoid hook portion 32 and flywheel shaft bearing bore
Wall contacts and scratches flywheel bearing hole wall, guarantees flywheel mass.
2 lower end of pull rod passes through balance plate 1, and 2 lower end of pull rod is equipped with the thrust plate 5 that diameter is greater than the diameter of pull rod 2, thrust plate
2 periphery of pull rod between 5 and balance plate 1 is equipped with second spring 6, and the both ends of second spring 6 hold out against thrust plate 5, balance plate 1 respectively
Bottom is clearance fit between pull rod 2 and balance plate 1, the locking member 7 for locking the two is equipped between thrust plate 5 and pull rod 2,
Locking member 7 is bolt, 2 lower end of pull rod is equipped with screw hole, and the pull rod 2 of the top of balance plate 1 is equipped with the diameter that diameter is greater than pull rod 2
Positive stop lug boss 8, second spring 6 can play buffer function when dismantling bearing, prevent two drag hooks 3 from not catching on bearing completely
When hydraulic device to pull rod 2 apply pulling force and product is damaged, improve dismantlement work stability.
The both ends of balance plate 1 are respectively provided with the limited block 9 that two drag hooks 3 of limitation rotate outward, and limited block 9 passes through
Bolt is mounted on balance plate 1, and limited block 9 is used to limit the scope of application of this tooling, guarantees the job stability of this tooling.
A kind of flywheel bearing method for dismounting will pass through bearing hole, unclamp two drag hooks 3 after two inside side compressions of drag hook 3
So that hook portion 32 is caught on bearing inner race, is pulled out bearing using hydraulic device tensile ties 2.
The utility model catches on bearing inner race by two drag hooks, reuses hydraulic device tensile ties bearing is disposable
It pulls out, it is easy to operate, high-efficient, 25 seconds/time are saved than conventional method；In disassembly bearing overall process without being struck to components
The case where beating, avoiding bearing unilateral stress, there is no the hidden danger for components of damaging, and can guarantee flywheel mass, effectively prevent
The case where components are scrapped in appearance generation, directly reduction rework cost.
Above are merely preferred embodiments of the utility model, it should be pointed out that for those skilled in the art,
