Description
Technical field
This utility model is related to the pushing meanss of main shaft bearing dismounting, is specifically related to the dismounting dress for main shaft bearing
Put, belong to mechanical design field.
Background technology
Equipped with many set bearings on the main shaft of heavy-duty machines, it is to carry out bearing is installed using hot-assembling method when installing bearing
, but when dismantling bearing it is impossible to heating, just cannot dismantle, if it is desired to dismounting bearing is it is necessary to use sledgehammer, constantly to bearing
Hammered, slowly could be unloaded lower bearing, this method for dismounting is not only wasted time and energy, and main shaft and main shaft part are all produced
Very big damage.The operation of enterprise is run to bring and has a strong impact on.
Content of the invention
In view of the defect that above-mentioned technology exists, the purpose of this utility model there is provided the promotion for main shaft bearing dismounting
Device, including main shaft, bearing, the shaft shoulder and top power disk, main shaft is installed bearing, bearing is adjacent with the shaft shoulder, and top is installed at shaft shoulder position
Power disk, top power disk is provided with tapped through hole with the mating surface of bearing inner race end face, during dismounting bearing, installs and screw thread on the power disk of top
The corresponding bolt of through hole, screws in bolt, and bearing demolition can be ejected by bolt.Ding Li disk center line and bearing face center
Line is identical.Tapped through hole on the power disk of top, diameter is not more than bearing inner race thickness, and tapped through hole is symmetrical, and quantity is not little
In 2.Because connecting machine, place-centric can not change for main shaft working end, so during dismounting bearing, installing one on main shaft
Support arrangement, the front and back position up and down of main shaft is fixed, and the dismounting realizing bearing does not interfere with main shaft operating position precision
Purpose.When the shaft shoulder is larger, has blocked bearing inner race, in the shaft shoulder away from the side installation top power disk of bearing, fix even with main shaft
Connect, the shaft shoulder arranges through hole with the mating surface of bearing inner race end face, and top power disk is provided with tapped through hole, axle with the mating surface of shaft shoulder end face
On shoulder, the aperture of through hole is more than the diameter of bolt, and the centrage of through hole is identical with the centrage of top power disk upper tapped through hole.This master
The pushing meanss of axle bearing dismounting can be used for the bearing removal of aerator transmission group.
Effective effect of the present utility model is：After dismounting main shaft bearing adopts fixed main shaft to support it is ensured that dismantling bearing, no
The operating accuracy of impact main shaft；Using top power disk dismounting bearing, there is no any damage to main shaft, dismounting speed improves than original
100 times.Bearing and various quick-wear part can smoothly be changed, not only convenient disassembly is reliable, cost-effective it is not necessary to whole link
Whole dismountings of main shaft, it is not necessary to original hammering, main shaft and main shaft part are all protected.Thus improving the work of machine
Efficiency, reduces the every cost of maintenance.

Fig. 3 is top power dish structure schematic diagram.
In figure, 1, main shaft, 2, bearing, 3, the shaft shoulder, 4, top power disk, 5, tapped through hole, 6, through hole
Specific embodiment
Specific embodiment 1
A kind of pushing meanss for main shaft bearing dismounting, including main shaft 1, bearing 2, the shaft shoulder 3 and top power disk 4；On main shaft 1
Bearing 2 is installed, bearing 2 is adjacent with the shaft shoulder 3, the shaft shoulder 3 position installation top power disk 4, the cooperation of top power disk 4 and bearing 2 inner ring end face
Face is provided with tapped through hole 5, during dismounting bearing 2, installs the bolt corresponding with tapped through hole 5, screw in bolt on the power disk 4 of top,
Bearing demolition 2 can be ejected by bolt, reaches the smooth effect dismantling bearing 2；Top power disk 4 center and bearing 2 end face center
Line is identical, and tapped through hole 5 diameter on the power disk 4 of top is not more than bearing 2 inner ring thickness, and tapped through hole 5 is symmetrical, and quantity is not
Less than 2.Because because connecting machine, place-centric can not change for main shaft 1 working end, so during dismounting bearing 2, on main shaft 1
One support means is installed, the front and back position up and down of main shaft 1 is fixed, realize not interfering with master to the dismounting of bearing 2
Axle 1 operating position precision.
Specific embodiment 2
A kind of pushing meanss for main shaft bearing dismounting, including main shaft 1, bearing 2, the shaft shoulder 3 and top power disk 4；On main shaft 1
Bearing 2 is installed, bearing 2 is adjacent with the shaft shoulder 3, the shaft shoulder 3, away from the side installation top power disk 4 of bearing 2, pushes up power disk 4 fixing with main shaft 1
Connect.The shaft shoulder 3 is provided with through hole 6 with the mating surface of bearing 2 inner ring end face, and top power disk 4 is provided with screw thread with the mating surface of the shaft shoulder 3 end face
Through hole 5, on the shaft shoulder 3, the aperture of through hole 6 is more than the diameter of bolt, the centrage of through hole 6 and the center pushing up power disk 4 upper tapped through hole 5
Line is identical.During dismounting bearing 2, the bolt corresponding with tapped through hole 5 installed on the power disk 4 of top, screw-in bolt, bolt can be by
Bearing demolition 2 ejects, and reaches the smooth effect dismantling bearing 2.Top power disk 4 centrage is identical with bearing 2 end face center line, top
Tapped through hole 5 diameter on power disk 4 is not more than bearing 2 inner ring thickness, and tapped through hole 5 is symmetrical, and quantity is not less than 2.?
Because connecting machine, place-centric can not change for main shaft working end, so during dismounting bearing 2, installing a support on main shaft 1
Device, the front and back position up and down of main shaft 1 is fixed, and realizes the dismounting of bearing 2 is not interfered with main shaft 1 operating position essence
Degree.
