Abstract
The invention discloses a bearing resolving device which is mainly composed of bolts, a supporting board, a screw and a gear. A threaded through hole is formed in the center of the supporting board. Two smooth through holes are symmetrically distributed in the two sides of the threaded through hole. The bolts penetrate through the smooth through holes in the supporting board and are connected with the supporting board through nuts. The screw is placed in the threaded through hole. The lower end of the screw is connected with the gear. A hook portion is arranged at the lower end of the bolt and a handle is arranged at the upper end of the screw. According to the bearing resolving device, the supporting board, the bolts and the screw are combined together, so that a tool capable of detaching a bearing conveniently is formed and the bearing resolving device is simple in structure, easy to manufacture, convenient to operate and capable of reducing labor resources, greatly improving the work efficiency and reducing the production cost.
Description
Technical field
The invention belongs to engine assembly technical field, specifically relate to a kind of bearing decomposer.
Background technology
Bearing is a kind of very important parts in contemporary plant equipment.Its major function is supported mechanical rotary body, the mechanical load coefficient of friction in order to reduction equipment in transmission process.Press the difference of motor element frictional property, bearing can be divided into rolling bearing and sliding bearing two classes.No matter be rolling bearing or sliding bearing, the decomposition of bearing and assembling process are all most important.Especially in the bearing decomposition and assembling process of engine, a lot of bearing assemblies all closely cooperate.Therefore the dismounting of bearing need to carefully operate, and does not slightly note damaging bearing and each parts.Yet, the decomposition of engine bearing is due to the reason of self structure at present, be difficult to adopt special-purpose disassembling tool, workman can only use other instrument to prize bearing in operating process, and operation is very lack of standardization like this, is difficult to accomplish the even application of force, very easily hurt bearing, thereby affect product quality, and operation is very inconvenient, operating efficiency is lower.
Summary of the invention
In order to address the above problem, the invention provides a kind of bearing decomposer.
The present invention is achieved by following technical solution.
A kind of bearing decomposer, mainly by bolt, support plate, screw and gear, formed, described support plate center is provided with a tapped through hole, in tapped through hole bilateral symmetry, be distributed with two smooth through holes, described bolt is through the smooth through hole on support plate, and be connected with support plate by nut, screw is placed in tapped through hole, and screw lower end is connected with gear.
Described bolt lower end is provided with crotch part.
Described screw upper end is provided with handle.
The line of centres of the tapped through hole on described support plate and two smooth through holes is straight line.
The rectangular shape of end face of described crotch part.
Described support plate is rectangle or circle.
The invention has the beneficial effects as follows:
Compared with prior art, the present invention is by adopting support plate, and bolt and screw combine, and form a kind of instrument of bearing for convenience detach, simple in structure, be easy to manufacture, easy to operate, reduced human resources, greatly improved operating efficiency, reduce production costs.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
1-bolt, 2-support plate, 3-nut, 4-screw, 5-gear, 11-crotch part, 41-handle.
The specific embodiment
Below in conjunction with accompanying drawing, further describe technical scheme of the present invention, but described in claimed scope is not limited to.
As shown in Figure 1, a kind of bearing decomposer of the present invention, mainly by bolt 1, support plate 2, screw 4 and gear 5, formed, described support plate 2 centers are provided with a tapped through hole, in tapped through hole bilateral symmetry, be distributed with two smooth through holes, the smooth through hole that described bolt 1 passes on support plate 2, and be connected with support plate 2 by nut 3, screw 4 is placed in tapped through hole, and screw 4 lower ends are connected with gear 5.In use, bolt 1 can freely rotate at the smooth through hole center on support plate 2, also can move up and down along the smooth through hole center line on support plate 2, by bolt 1, freely rotates and move up and down the decomposition realizing bearing.
Described bolt 1 lower end is provided with crotch part 11.
Described screw 4 upper ends are provided with handle 41.Like this can operating grip 41 height and position of adjustment screw 4 easily.
Tapped through hole on described support plate 2 and the line of centres of two smooth through holes are straight line.
The rectangular shape of end face of described crotch part 11.
Described support plate 2 is rectangle or circle.In use can select according to concrete service condition the shape and structure of support plate 2.
As shown in Figure 1, adopt bearing decomposer of the present invention when carrying out bearing decomposition, its operating procedure is as follows:
(1) regulate decomposer of the present invention to initial position: rotary handle 41, screw 4 bottoms are withstood on gear 5, adjust the bottom of screw 4 higher than the bottom of the crotch part 11 of bolt 1,11 rotations of the crotch part of bolt 1 are extremely to 90 ° of angle localities with two bolt 1 lines of centres;
(2) decomposer of the present invention is vertically put on spare part to be decomposed, and the position that makes bolt 1 is corresponding with in groove on spare part to be decomposed;
(3), by the supercentral tapped through hole direction of the crotch part of bolt 1 11 cycle support plate 2, rotating nut 3, makes the crotch of bolt 1 partly hook the lower end of steel bushing in bearing to be decomposed;
(4) rotary handle 41, screw 4 is withstood on gear 5, thereby bearing is taken out.
The present invention is simple in structure, easy to operate, uniform force application, can easily bearing be decomposed, and operating efficiency is high.
Claims (6)
1. a bearing decomposer, mainly by bolt (1), support plate (2), screw (4) and gear (5), formed, it is characterized in that: described support plate (2) center is provided with a tapped through hole, in tapped through hole bilateral symmetry, be distributed with two smooth through holes, described bolt (1) is through the smooth through hole on support plate (2), and be connected with support plate (2) by nut (3), screw (4) is placed in tapped through hole, and screw (4) lower end is connected with gear (5).
2. a kind of bearing decomposer according to claim 1, is characterized in that: described bolt (1) lower end is provided with crotch part (11).
