Description
Technical field
The utility model belongs to aid technical field, particularly relates to a kind of 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, and customizability is strong, simple to operate, practical, is particularly useful for the 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 bearing extractor, comprise support set, support thick stick, drawing fixed bar and sliding sleeve, support thick stick is fixedly mounted on the inner of drawing fixed bar, on support thick stick, be set with support set, on drawing fixed bar, be set with sliding sleeve, in drawing fixed bar outer end face, be provided with flange simultaneously, described support set surface is radially provided with multiple grooves, support set is provided with flange at groove initiating terminal, and support set is pyramidal structure chamber at groove initiating terminal inner chamber, support thick stick the inner is provided with the conical nose mating with this pyramidal structure chamber.
Be provided with limiting gasket in drawing fixed bar the inner.
Described support thick stick is fixedly connected with the inner screw thread of drawing fixed bar.
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 bearing extractor comprises support set, support thick stick, drawing fixed bar and sliding sleeve, it adopts the principle of similar setscrew, bearing is blocked with the flange of support set, after make sliding sleeve outward flange fast moving and collision, utilize the inertia force of sliding sleeve that bearing is extracted, simple in structure, be easy to manufacture; When work, support set is pressed into bearing bore diameter, then drawing fixed bar and support thick stick are tightened, then the drawing of fast moving sleeve just can be got off bearing removal, simple to operate, practical.
2, structurally, the utility model is provided with limiting gasket in drawing fixed bar the inner, from in the inner landing of drawing fixed bar, also increase the contact area between support set and drawing fixed bar at anti-skidding sleeve, made the transmission more reliable, more effective of inertia force; Described support thick stick is fixedly connected with the inner screw thread of drawing fixed bar, is convenient to installation and removal, easy to use; This extracting tool adopts 45 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 Qie You tetra-road grooves, utilize toughness and the elasticity of steel, have realized the folding of support set, do 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 external taper, and the simple processing and manufacturing of real support set part-structure is easier.
4, to sum up, the utility model 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.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail, wherein:
Fig. 1 is the structural representation that the utility model bearing extractor uses state;
Fig. 2 is the perspective view that the utility model bearing extractor uses state;
Sequence number in figure: 1, drawing fixed bar, 2, sliding sleeve, 3, limiting gasket, 4, support set, 5, bearing, 6, support thick stick, 7, flange, 8, groove, 9, flange.
the specific embodiment
Embodiment mono-:
Referring to Fig. 1, Fig. 2, in figure, the utility model bearing extractor, comprise support set 4, support thick stick 6, drawing fixed bar 1 and sliding sleeve 2, support thick stick is fixedly mounted on the inner of drawing fixed bar, on support thick stick, be set with support set, on drawing fixed bar, be set with sliding sleeve, in drawing fixed bar outer end face, be provided with flange 7 simultaneously, described support set surface is radially provided with 4 road grooves 8, support set is provided with flange 9 at groove initiating terminal, and support set is pyramidal structure chamber at groove initiating terminal inner chamber, and support thick stick the inner is provided with the conical nose mating with this pyramidal structure chamber.
Be provided with limiting gasket 3 in drawing fixed bar the inner.
Described support thick stick is fixedly connected with the inner screw thread of drawing fixed bar.
This extracting tool adopts 45 Steel materials to make.
The course of work of the present utility model is as follows:
Referring to Fig. 1, when work, support set 4 is pressed into bearing 5 internal diameters, again drawing fixed bar 1 and support thick stick 6 are tightened, support thick stick struts support set the inner, itself and bearing inner race are compressed, and utilize the inner flange 9 of support set that bearing inner race end face is blocked, then by sliding sleeve 2 to drawing fixed bar end flange 7 fast moving and bump, thereby utilize the inertia force of weight that bearing is extracted, operate easy to use.
The foregoing is only the schematic specific embodiment of the utility model; not in order to limit scope of the present utility model; any those skilled in the art is not departing from equivalent variations and the modification under the prerequisite of the utility model design and principle, made, all should belong to the scope of the utility model protection.
