Abstract

Disclosed is a mounting and dismounting device of a bearing. A bottom portion platen is arranged on the device. A hydraulic cylinder is perpendicularly installed on the central portion of the bottom portion platen. Four stand columns are installed around the bottom portion platen. The mounting and dismounting device of the bearing is characterized in that a working platen is installed on the upper end portion of each stand column. Along the radius direction, a plurality of strip-shaped holes are formed in the outer edge portion of each working platen. A bolt penetrates through each strip-shaped hole from bottom to top, and the bolts can move in the strip-shaped holes. A strip-shaped pressing plate is installed on each bolt, and a cushion block is arranged on each strip-shaped pressing plate in a matched mode. A large round hole is formed in the central portion of the work platen so that a piston ejector rod of the hydraulic cylinder can penetrate through the round hole. A bearing supporting plate is arranged on the head portion of the piston ejector rod of the hydraulic cylinder in a matched mode, and a hydraulic operating device is arranged on the hydraulic cylinder in a matched mode.

Description

A kind of installation and removal device of bearing
Technical field
The utility model relates to a kind of bearing installation and removal device, particularly relates to a kind of installation and removal device of electric motor end cap bearing.
Background technology
At present, when the bearing installation or removal operation of carrying out electric motor end cap, be to carry out craft with copper rod to beat and carry out installation or removal owing to do not have special equipment, usual way.This method one of carrying out installation or removal of beaing by hand is that the efficient of operation is too low, wastes time and energy; The 2nd, workpiece is caused damage easily, often because beaing error to bearing and bearing mounting hole injury, make bearing cracking subscription rate when serious, affected the repair quality of motor.Chinese utility model patent application (application number 201020502188.7) has proposed a kind of dismounting bearing arrangement that uses hydraulic jack.Although this device can improve the efficient of operation, weak point is the field-strip that this device can only be used for carrying out bearing, and can not be used for carrying out the installation exercise of bearing, and can only dismantle a kind of bearing of specification.
The utility model content
The purpose of this utility model just provides a kind of bearing installation and removal device that uses hydraulic jack, it not only can be increased work efficiency, and can be used for carrying out the installation exercise of bearing, also can be used for carrying out the field-strip of bearing, and can carry out the bearing installation and removal of plurality of specifications size, can guarantee again the quality of construction operation simultaneously.
For achieving the above object, the utility model has adopted following technical scheme:
A kind of installation and removal device of bearing, this device has a base platen, in the centre of base platen a hydraulic cylinder is housed vertically, and four root posts are housed around base platen, the piston mandril height of the aspect ratio hydraulic cylinder of column is slightly higher, it is characterized in that:
A also is equipped with a working plate in the upper end of column, and the height of this working plate is on the piston mandril head of hydraulic cylinder,
B has a plurality of bar holes in the outer edge of working plate along radial direction, is installed with from the bottom to top a bolt in each bar hole, and this bolt can move in bar hole,
C is equipped with respectively a strip plate on each bolt, each strip plate is furnished with a cushion block,
D has a larger circular hole at the central part of working plate.
The piston mandril head of e hydraulic cylinder is furnished with a bearing supporting plate,
The f hydraulic cylinder also is furnished with the hydraulic operating device.
The quantity of the bar hole on the working plate is more than three or three.
Described hydraulic operating device is the hand-hydraulic powder operation device, or the electric hydaulic powder operation device.
Compared with prior art, the utility model has the advantages that: because this bearing installation and removal device has been Duoed a working plate than common bearing disassembling device.This platen be equipped with can reducing bar hole and bolt clip plate thereof, therefore, electric motor end cap and bearing that this bearing installation and removal device can dismounting plurality of specifications size.Again since electric motor end cap and bearing can be installed in forward and reverse mode on this device, and during forward and reverse installation, because the Way out of dead eye is different, therefore, when bearing is subject to the push rod thrust of hydraulic cylinder, just can be by jacking from electric motor end cap or release.Therefore, the bearing that this device both can the mounted motor end cap also can be dismantled the bearing of electric motor end cap.Simultaneously, because the effect of this assembly axis supporting plate, the thrust that acts on the bearing is more even, can not destroy the structural behaviour of bearing, and therefore, this device can improve the operation quality of installation or removal bearing.
Description of drawings
Fig. 1 is the structural representation of bearing installation and removal device.
The specific embodiment
Referring to Fig. 1, the concrete structure of bearing installation and removal device of the present utility model is such: this device has a square base platen 11, and a root post 7 respectively has been welded on four angles of base platen 11.Be placed with a hydraulic cylinder 10 in the centre of base platen 11, the piston mandril head of hydraulic cylinder 10 is placed with a bearing supporting plate 9.The working plate 5 of the circle that is welded in the upper end of four root posts 7 has three bar holes 6 in the outer edge of working plate 5.In three bar holes 6 to lower and on be installed with respectively a bolt 3.A strip plate 2 is housed respectively on the bolt 3, and each strip plate 2 respectively is furnished with a cushion block 4.Hydraulic cylinder 10 also is furnished with an electric hydraulic pump 12.During work, electric motor end cap 1 is placed on the working plate 5, and bearing 8 is placed on the bearing supporting plate 9.
When this device is used for bearing on the mounted motor end cap, just electric motor end cap 1 is placed on the working plate 5, bearing mounting hole on its electric motor end cap 1 down, adjust after the centering electric motor end cap 1 with the strip plate 2 on the bolt 3 and be equipped with cushion block 4 with electric motor end cap 1 compression, it is fixed on the working plate 5.Then with electric motor end cap 1 used bearing 8 be placed on the bearing supporting plate 9, and allow bearing 8 aim at the bearing mounting hole of electric motor end caps 1.After ready, start electric hydraulic pump 12, move on slow with the piston mandril impeller-hub supporting plate 9 of hydraulic cylinder 10 and bearing thereof 8.At last, bearing 8 is pressed in the bearing mounting hole of electric motor end cap 1, has reached harmless bearings mounted purpose.
When this device is used for dismantling bearing on the electric motor end cap, just electric motor end cap 1 is placed on the working plate 5, bearing mounting hole on its electric motor end cap 1 up, adjust after the centering electric motor end cap 1 with the strip plate 2 on the bolt 3 and be equipped with cushion block 4 with electric motor end cap 1 compression, it is fixed on the working plate 5, then bearing supporting plate 9 is put on the piston mandril of hydraulic cylinder 10, make its bearing that just in time is in electric motor end cap 18 under the position.After ready, start electric hydraulic pump 12, move on slowly with the piston mandril impeller-hub supporting plate 9 of hydraulic cylinder 10, waiting when contacting bearing 8, continue again to promote bearing 8 and move on slow.At last, outside the bearing mounting hole with bearing 8 push-out motor end caps 1, reached the purpose of nondestructive demounting bearing.
When this device was used for the bearing of electric motor end cap of installation or removal different specification size, suitably the screw rod 3 in the mobile bar hole 6 made it adapt to the different size of electric motor end cap, in order to be fixed, thereby carries out installation or removal work.
