Technical field
The present invention relates to bearing assembly equipment technology, more particularly to a kind of bearing tool for assembling.
Background technology
It is the part commonly used in rail vehicle to roll axle suspension bearing.
Existing rail vehicle is during equipment, and rolling the inner ring of axle suspension bearing needs first to be set on axletree, Zhi Houtong
Cross and tap the port that the inner ring for making rolling axle suspension bearing is embedded in axle suspension bearing box, so that the inner ring and the port card of axle suspension bearing box of rolling axle suspension bearing
Hold positioning.
However, during percussion, easily there is deflection in the inner ring for rolling axle suspension bearing, reduces the precision of assembling.
The content of the invention
The present invention provides a kind of bearing tool for assembling, to improve assembly precision.
The present invention provides a kind of bearing tool for assembling, including：
Sleeve, the internal diameter of the sleeve has setting value, so that the sleeve can be set on axletree；
At abutting part, the bottom port for being arranged on the sleeve, the abutting part is used to abut against with the inner ring of bearing；
Handle, is arranged on the sleeve outer surface along the sleeve is radially projecting.
Based on above-mentioned, the bearing tool for assembling that the present invention is provided, for the assembling of the inner ring and axle suspension bearing box of bearing, its
In, axletree is equipped with axle suspension bearing box, in assembling process, first the inner ring of bearing can be set on axletree, and by bearing
Circle is moved to the port of axle suspension bearing box along axletree, sleeve is set on axletree afterwards, and make the inner ring phase of abutting part and bearing
Abut, staff to the inner ring of bearing can apply power towards axle suspension bearing box by handle afterwards, while rotate axle suspension bearing box, from
And the inner ring of bearing is embedded in and is held in the port of axle suspension bearing box by revolving force, complete the inner ring and axle suspension bearing box of bearing
Assembling.Because the power that staff applies to handle can uniformly pass to the inner ring of bearing by sleeve and abutting part,
Therefore, the deflection of the inner ring of bearing is not easily caused, improves the precision of assembling.

Embodiment
It refer to Fig. 1 and Fig. 2, bearing tool for assembling provided in an embodiment of the present invention, including：Sleeve 101, the sleeve
101 internal diameter has setting value, so that the sleeve 101 can be set on axletree 201；Abutting part 102, is arranged on the set
At the bottom port of cylinder 101, the abutting part 102 is used to abut against with the inner ring 202 of bearing；Handle 103, along the sleeve
101 radially projecting are arranged on the outer surface of sleeve 101.
Bearing tool for assembling in the present embodiment, for the assembling of the inner ring 202 and axle suspension bearing box 203 of bearing, wherein, embrace
Axletree 201 is equipped with axle box 203, in assembling process, first the inner ring 202 of bearing can be set on axletree 201, and by axle
The inner ring 202 held is moved to the port of axle suspension bearing box 203 along axletree 201, and sleeve 101 is set on axletree 201 afterwards, and makes
The inner ring 202 of abutting part 102 and bearing is abutted against, afterwards staff can by inner ring 202 from handle 103 to bearing apply court
To the power of axle suspension bearing box 203, while rotating axle suspension bearing box 203, so as to enable the inner ring 202 of bearing to be embedded in and block by revolving force
Hold in the port of axle suspension bearing box 203, complete the inner ring 202 of bearing and the assembling of axle suspension bearing box 203.Because staff is to handle
Therefore 103 power applied, can easily not caused by sleeve 101 and the uniform inner ring 202 for passing to bearing of abutting part 102
The deflection of the inner ring 202 of bearing, improves the precision of assembling, while the inner ring 202 for reducing bearing is embedded in the end of axle suspension bearing box 203
The difficulty of mouth, is operated more laborsaving.In addition, in the prior art, when the inner ring 202 to bearing is tapped, tapping on thing
Residue easily falls into Bearing inner and produces influence to the running of bearing, causes the damage of bearing, and uses in the present embodiment
Bearing tool for assembling then can complete the inner ring 202 of bearing and the assembling of axle suspension bearing box 203 without carrying out percussion, therefore, it is possible to keep away
Exempt from the generation of residue, improve the reliability that bearing is used.
In the present embodiment, it is preferred that abutting part 102 is along the radially projecting bottom for being arranged on the sleeve 101 of the sleeve 101
On the outside of portion port.Thus, the stability abutted against beneficial to the inner ring 202 for improving abutting part 102 and bearing.
In the present embodiment, it is preferred that abutting part 102 is formed with bearing surface, the bearing surface be used for in the bearing
Circle 202 forms face contact.Thus, beneficial to the contact area of increase abutting part 102 and the inner ring 202 of bearing, so as to improve abutting
The stability that the inner ring 202 of portion 102 and bearing is abutted against.
In the present embodiment, it is preferred that abutting part 102 is annular, the described annular and coaxial line of sleeve 101.Thus, it is sharp
In the contact area of increase abutting part 102 and the inner ring 202 of bearing, so that the inner ring 202 for improving abutting part 102 and bearing offsets
The stability connect.
In the present embodiment, it is preferred that abutting part 102 and the sleeve 101 are formed in one structure.Thus, beneficial to raising
The bonding strength of abutting part 102 and sleeve 101.
In the present embodiment, it is preferred that the bottom of abutting part 102 is provided with damping mat 104, the damping mat 104 is used for and institute
The inner ring 202 for stating bearing is in contact.Because abutting part 102 is in contact by damping mat 104 with the inner ring 202 of bearing, therefore profit
In improving the frictional force between abutting part 102 and the inner ring 202 of bearing, in the rotary course of axle suspension bearing box 203, make abutting part 102
