Description
Technical field
The utility model belongs to aid technical field, particularly relates to a kind of ejecting type bearing extractor.
Background technology
Larger bearing mainly uses the method for heat expansion and shrinkage to carry out dismounting now, and little bearing uses wooden mallet and copper rod to carry out dismounting.But sometimes working space is narrow and small, bring very burden to dismounting.And buying specific purpose tool cost height is not necessarily suitable for.Therefore, the bearing of work on hand narrow space often adopts welding or Methods of OFC-A to carry out damage type dismounting.The method causes inefficiency, and other parts are also had to destroying infection.
Summary of the invention
The technical problems to be solved in the utility model overcomes above-mentioned the deficiencies in the prior art exactly, and provides a kind of simple and reasonable for structure, is easy to manufacture, customizability is strong, simple to operate, practical, be particularly useful for the ejecting type bearing extractor of small space bearing removal.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of ejecting type bearing extractor, comprise folding sleeve, inner sleeve, screw mandrel, fixing thick stick and rotation thick stick, in folding sleeve, be provided with screw mandrel, screw mandrel end is horizontally installed with rotation thick stick, between folding sleeve and screw mandrel, be provided with inner sleeve, between inner sleeve and screw mandrel, screw thread coupling is connected, inside put and be fixedly installed fixing thick stick, and fixing thick stick stretches out from folding sleeve lateral wall, described folding sleeve is radially provided with multiple (as 4 roads) groove, folding sleeve is provided with flange at groove initiating terminal, and folding sleeve is pyramidal structure chamber at groove initiating terminal inner chamber, screw mandrel end that should pyramidal structure chamber is provided with to the conical nose matching with it.
The end of described screw mandrel is laterally provided with installing hole, and rotation thick stick passes in installing hole.
This extracting tool adopts 45 Steel materials to make.
The beneficial effect of technical solutions of the utility model is:
1, structurally, the utility model ejecting type bearing extractor comprises folding sleeve, inner sleeve, screw mandrel, fixing thick stick and rotation thick stick, and it adopts the principle of similar setscrew, bearing is blocked, after utilize screw structure that bearing is ejected, simple in structure, be easy to manufacture; When work, folding sleeve is inserted to bearing bore diameter, rotating rotation thick stick folding sleeve can strut, thereby bearing inner race is blocked, and being then rotated further rotation thick stick can eject bearing, only needs to rotate rotation thick stick compared with drawing type, simple to operate, practical.
2, structurally, the end of screw mandrel described in the utility model is laterally provided with installing hole, and rotation thick stick passes in installing hole, simple in structure, reasonable in design; This extracting tool mainly adopts 45 common Steel materials to make, and part processing is simple, has the producer needing to manufacture according to the actual demand of oneself, also can make a series of bearing extractor, and customizability is strong; In addition, the utility model is particularly useful for small space bearing removal, and through applying in bearing in reduction gears dismounting, fully proves that its dismounting effect is better, simple to operate, practical.
3, structurally, the utility model extracting tool support set part has been cut multiple tracks (such as 4 roads) groove, utilizes toughness and the elasticity of steel, has realized the folding of support set, does not need other special elastomeric materials; This extracting tool support set initiating terminal has flange, can block better bearing, increases the service life; This extracting tool support set inside is internal taper, and having realized blocking bearing and ejecting bearing two step operations only needs rotation swingle one step to realize, easy for operation.
4, to sum up, the utility model ejecting type bearing extractor is simple in structure, reasonable in design, is easy to manufacture, and customizability is strong, simple to operate, practical, is particularly useful for small space bearing removal, and range of application is wider, therefore, is very suitable for promotion and implementation.
