Description
Technical field
The invention belongs to mechanical maintenance tool in use field, relate to the extracting tool of bearing and protective metal shell or non metallic sheath, specifically, is a kind of impact adjustable internal puller.
Background technology
In motor vehicles maintenance, often occur the situation that bearing cannot be pulled down from outside running into such situation, just must by after whole wheel hub dismounting, again from inside dismounting bearing, complex operation, not only time-consuming, take a lot of work, require great effort, and be inserted tight fit between bearing and sheath (bearing block), not easily set about, in addition demolition works is comparatively large, easily occurs to squeeze hand, touch hand, causes personal injury.
For this reason, someone have devised bearing extractor, roll over a crotch in one end of crowbar, crotch is stretched in bearing inner race hole, hook the inner ring of bearing from outside, then hold crowbar with two and pull outward, bearing is transferred to from sheath (bearing block), this allocation mode of stretching the meaning has obvious shortcoming, be exactly the bad grasp of dynamics, strength is little, and bearing is motionless, strength is large, usually other strength, because crowbar only has an impetus, strength is uneven, strength is too large, easily damages bearing or sheath.Therefore, urgent need research and development are a kind of facilitates handy bearing extractor.
Summary of the invention
For solving the problem, the object of this invention is to provide a kind of impact adjustable internal puller, operation smoothly, facilitates handy, and dismounting is quick, saves time, saving of labor, laborsaving, is applicable to the dismounting of plurality of specifications bearing.
