Abstract
The invention relates to a disassembly tool, in particular to a bearing-disassembling composite set, aiming at solving the technical problem that bearings are immediately damaged if being disassembled. The bearing-disassembling composite set comprises a removable tyre, a tyre plate, and at least two draw bars, wherein the removable tyre is abutted against a bearing inner race and divided into an upper tyre and a lower tyre; the upper tyre and the lower tyre are of semi-circular shapes with the same diameter and are combined to form an integral circle; the circular edge of the upper tyre is provided with a screwed hole which extends to the lower tyre, so that the upper tyre and the lower tyre are fixed into a whole by bolts; the tyre plate is provided with at least two through holes; and two ends of each draw bar are provided with threads. The bearing-disassembling composite set is simple in structure, is convenient and practical, applies even force to the bearing inner race, and ensures that bearing steel balls, retainers, inner race structure and outer race structure are not deformed during the bearing disassembling process, thus reaching the technical purpose of safe disassembly.
Description
Technical field
The present invention relates to a kind of extracting tool, specifically be meant a kind of bearing removal composite set.
Background technology
Bearing belongs to the parts of comparison precision in motor, and is worth not low.The situation of dismounting bearing often need to take place in motor in maintenance.Common bearing drawer directly acts on bearing outer ring with pulling force, by steel ball and retainer, pulling force is passed to bearing inner race, and bearing is pulled out from axle.Destroyed bearing fully as the method, the bearing 100% under the dismounting damages and can not re-use.
Summary of the invention
Tear destroyed technical problem open for overcoming present bearing one, the invention provides a kind of bearing removal combination tool.
The technical solution used in the present invention is: the bearing removal combination tool, comprise a tire alive that offsets with bearing inner race, the tire of living is divided into tire and following tire, last tire, following tire are the semi-annular shape of same diameter, last tire, following tire are combined to form complete circle, be provided with the screwed hole that downward tire extends from the edge of last tread ring shape, will go up tire, play tire to be fixed as one by bolt; One tire plate is provided with two through holes at least on the tire plate; At least two pull bars, the two ends of pull bar are provided with screw thread.
The described tire of going up, the position of tyre bead edge is provided with the right angle breach on the screwed hole correspondence.
Shape of through holes on the described tire plate is a slotted eye.
Beneficial effect of the present invention: comprised the tire alive that combines by last tire, following tire in this bearing removal combination tool, the tire of living can be installed on the motor shaft between bearing and the internal bearing cover easily, by pull bar pulling force is transmitted on the tire alive, the tire of living directly acts on power on the inner ring of bearing again, thereby bearing is intactly disassembled.This bearing removal combination tool is simple in structure, convenient and practical, to the bearing inner race uniform force application, can guarantee the indeformable of bearing removal process middle (center) bearing steel ball, retainer and inner ring, outer ring structure, reaches the technical purpose of safety dismounting.

The specific embodiment
The present invention will be further described below in conjunction with drawings and Examples.
The bearing removal combination tool comprises a tire alives that offsets with bearing inner race, and the tire of living is divided into tire 1 and following tire 2; One tire plate 5; Pull bar 7.
As shown in Figure 1, the last tire 1 of the tire of living, following tire 2 are the semi-annular shape of same diameter, and last tire, following tire are combined to form complete circle, are provided with the screwed hole 3 of downward tire extension from the edge of last tread ring shape.As shown in Figure 4, last tire 1, following tire 2 are to be fixed as one by hexagon socket head cap screw 15.
As shown in Figure 1, in the present embodiment, install easily for making the fixing hexagon socket head cap screw 15 of going up tire, following tire, last tire is provided with right angle breach 4 in the position of screwed hole corresponding edge.Certainly, if this right angle breach 4 does not exist, screwed hole 3 is directly stretched out by last tire 1 edge also can realize the fixing of tire 1, following tire 2.
As shown in Figure 2, for after making pull bar 7 and tire plate 5 being connected, tire plate 5 forms a stable stress surface, is provided with two through holes 6 at least so that fixing with at least two pull bars 7 on tire plate 5.In the present embodiment, the quantity of the through hole 6 on the tire plate 5 is 4, and pull bar 7 also is 4 certainly.
As shown in Figure 4, because an end of pull bar 7 is fixing with tire plate 5, an end is fixing with internal bearing cover 10, is on the same straight line through hole 6 employing slotted eye shapes for making through hole 6 on the tire plate 5 and the screw on the internal bearing cover 10.
As shown in Figure 3, the two ends of pull bar 7 are provided with screw thread 8, and in the present embodiment, the quantity of pull bar 7 is 4.
During actual the use, as shown in Figure 4, according to the specification of internal bearing cover, axle, bearing, design live tire, tire plate, pull bar disassemble bearing is intact with assurance, and concrete steps are as follows:
1, the tire of will living places between bearing 11 and the internal bearing cover 10, and last tire 1, tire 2 is enclosed within respectively on the motor shaft 12 down, is connected into hexagon socket head cap screw 15;
2,, select suitable pull bar 7 according to the armature spindle elongation.Pull bar 7 one ends are screwed on the internal bearing cover 10, and an other end adopts nut 9 to be connected and fixed by the through hole on the tire plate 56;
3, adjust the distance of 5 of internal bearing cover 10 and tire plates, jack 13 is placed between tire plate and the motor shaft end face;
4, move up and down oil pump handle 14, make jack 13 protruding, masterpiece is used for tire plate 5,, power is passed to bearing 11 by pull bar 7, internal bearing cover 10, the tire of living;
5, under the effect of jack 13, stably bearing 11 is disassembled.
In practical application schematic diagram shown in Figure 4, jack 13 conducts a kind of force application means wherein, certainly can also adopt other force mechanism, such as screw rod application of force or the like, as long as applied force finally can steadily act on the tire plate 5, and power is enough big, just bearing can be disassembled reposefully.
This combination tool, because the tire of increase living between internal bearing cover 10 and bearing 11, the work tire directly puts on power on the inner ring of bearing 11, it is hereby ensured unlikely damage in the unloading process of bearing 11.
