Description
Technical field
The invention belongs to technical field of bearings, more particularly to a kind of bearing installation and extracting tool.
Background technology
The mounting means of bearing has hand hammer at present or copper rod taps press-in or press press-in.These traditional methods exist
Some more special occasions, using just having significant limitation, such as the installation and removal of robot wheel group bearing, because of structure
Limitation, cause firmly to tap, hand hammer or copper rod can not be used to tap press-in, more have no idea using the instruments such as press into
Row operation.
For example, the dismounting for bearing, current most common instrument is to draw horse, with a kind of simatool axis from Switzerland
It is best to hold dismantling device MK1030, needs to go deep into pulling force hook foot among bearing steel ball when dismantling bearing, such instrument
It is more handy for the large-scale burden bearing of no sealing cover, but for having sealing cover and small size bearing with regard to helpless.
Common La Mayinlama stretches out the size of foot and the limitation of operating space, can not be realized for compact-sized place.In addition draw
Horse needs center to have impetus, is motor output shaft or the accurate part of comparison for center, drawing the operation of horse cannot expire
Foot requires.
Chinese patent CN201410254456 discloses a kind of electric mainshaft bearing installation and provision for disengagement, including thread spindle
Frame, support pressing plate, spanner, self-aligning thrust roller bearing, radical length adjustment frame, connecting rod, claw hook, adjustment pin and straight pin；
The screw thread pedestal is mounted on the top of screw thread pedestal with support pressing plate thread fitting, the spanner, and the screw thread pedestal passes through
Self-aligning thrust roller bearing connects radical length adjustment frame, and the connecting rod is along the circumferential direction uniformly mounted on radical length adjustment frame
On, and by adjusting the position of pin adjusting connecting rod, the claw hook passes through cylinder pin connection connecting rod.The device is suitable for manually peace
Dress realizes the installing and dismounting to different pore size bearing, compact in structure and convenient to use, system in the case where not damaging bearing substantially
It makes of low cost.Although the invention is to generate displacement by relative rotation to dismantle, Plane Installation structure cannot be still solved
Bearing removal problem, in the invention, still using the side wall for hanging bearing, that is, require in structure middle (center) bearing
Sky, cannot be hollow for structure or in special occasions, and such invention cannot still solve the problems, such as.
The content of the invention
In the chassis of Intelligent Mobile Robot, because structure needs, bearing, hub support set and motor fixation are arranged
Meter becomes planar structure, and motor output shaft drives end cap to rotate, and end cap is fixed with wheel hub, and such motor band runner hub rotates.This
Sample it is simple and compact for structure, it is very valuable for crusing robot.But such structure is whether being installed or needed
It when dismounting, is all greatly limited, when especially later maintenance needs dismounting, common common method is substantially in a helpless situation
Without plan, for example horse is drawn, the drag hook for drawing horse is both hung without position, also without top between the top pull Malaysia and China of position.Violence is dismantled
It is exactly injuring part to lose motor output shaft.
The present invention seeks to solve the part that can conveniently carry out installation and removal relative rotation in planar structure
And bearing.
For above-mentioned technical purpose, the present invention will take following technical solution：
A kind of bearing installation and extracting tool, it is described to usher to seat including nut of usheing to seat, screw rod of usheing to seat, long spiro nail and short screw
The screw rod of nut and screw rod of usheing to seat coordinates, and nut of usheing to seat moves up and down along screw rod of usheing to seat；The short screw will usher to seat screw rod with electricity
Machine fixing sleeve connects, and motor fixing sleeve is fixed together with bearing；The long spiro nail nut that will usher to seat is connected with wheel hub；Work as fixation
Wheel hub rotates usher to seat screw rod or fixed usher to seat screw rod, rotary hub, and bearing and wheel hub generate displacement, complete the dismounting of bearing
And installation.
As a further improvement on the present invention, the base portion of the screw rod of usheing to seat is hollow design, and motor output shaft is stretched
Entering the hollow space to screw foot of usheing to seat, the hollow least radius of screw foot is more than the maximum radius of motor output shaft, this
The purpose done is for empty avoiding motor output shaft, and protection motor output shaft is being installed with being damaged in disassembly process from external force,
Short screw usage quantity at this time is according to actual conditions difference unrestricted choice.
As a further improvement on the present invention, the base portion of the nut of usheing to seat is hollow design, and screw foot stretches into
To the hollow space of nut pedestal, the hollow least radius of nut pedestal is more than the maximum radius of screw foot, the mesh done so
Be the installation seating portion of screw rod of usheing to seat for empty avoiding, avoid influence between the two, long spiro nail usage quantity at this time according to
Actual conditions difference unrestricted choice.
Further, the screw end head of usheing to seat is tetragonal end, and tip shapes herein are not limited in quadrangle,
Correspondingly, hexagon also can, as long as convenient wrench fixed end can be played the role of, all within protection scope of the present invention.
Further, the size of the screw foot and nut pedestal changes according to the size of bearing, the screw rod
Pedestal and nut pedestal are equipped with Multiple Type, so can preferably adapt to various working environments.
According to above-mentioned technical solution, compared with the prior art, the present invention has following advantageous effect：
1), relatively existing technical solution, the configuration of the present invention is simple is at low cost, and structure is reliable, easy for installation, Er Qieke
To adjust processing /V size as needed in a variety of occasions, various complicated rings can also be adapted to using a variety of materials
Border has extensive use.
2), before because the designing scheme that bearing installation and removal problem is evaded, because the present apparatus, can directly be set
Meter application.
3), whole dismounting and installation process smooth-going, without the action of any percussion and strike, for installation part and axis
The precision held has obtained maximum protection.
