Abstract
A kind of transmission bearing press-loading apparatus, it is characterised in that：Including aligning head, end cap, mandrel, lead, aligning head is hemisphere, aligning head is put into mandrel, aligning head shoot face coordinates with the bellmouth in mandrel, ensure that sphere freely rotates, aligning head and bonding press plane contact, aligning head pass through end cap connecting mandrel, mandrel inserts brearing bore, mandrel alignment bearings inner ring by lead.After the faying face of lead and mandrel body is contacted positioning with bearing inner race, start press, when bonding press encounters the contact surface of aligning head, aligning head is freely rotated by sphere finds plane accurately automatically.If bonding press plane is uneven, the plane of aligning head can rotate automatically to be adjusted to make plane be bonded bonding press plane, due to rotational angle very little, therefore mandrel will not be caused to offset, simultaneously because the guide effect of lead, ram pressures can be transmitted vertically, ensure that bearing will not press inclined phenomenon during press fitting, improve bearing press mounting process qualification rate.
Description
Technical field
It the utility model is related to a kind of transmission bearing press-loading apparatus.
Background technology
During press fitting transmission case housing bearing process, universal press press fitting is typically used.Press fitting process middle (center) bearing or bearing
The positioning of outer ring is very crucial, if to easily cause bearing press mounting crooked for locating bias, is sheared with shell inner hole, due to axle
Hold deflection and cause bearing and gear eccentric wear, accelerating gear abrasion, increase noise, shorten gearbox life.Therefore pressing bearing or
Bearing outer ring is, it is necessary to special positioning tool, and pressure head is not that axially loaded will be made in the event of crooked when preventing bearing press mounting
The problem of generation shear inference gearbox life with housing crooked into bearing.
The content of the invention
The purpose of this utility model is to provide a kind of transmission bearing press-loading apparatus, overcomes and used universal press pressure originally
It is crooked that dress easily causes bearing press mounting, the shortcomings that causing assembly detection noise test failure.
A kind of transmission bearing press-loading apparatus, it is characterised in that：Including aligning head, end cap, mandrel, lead, aligning head
For hemisphere, aligning head is put into mandrel, and aligning head shoot face coordinates with the bellmouth in mandrel, ensures that sphere freely rotates, aligning
Head and bonding press plane contact, aligning head insert brearing bore, mandrel pair by end cap connecting mandrel, mandrel by lead
Quasi- bearing inner race.After the faying face of lead and mandrel body is contacted positioning with bearing inner race, start press, work as bonding press
When encountering the contact surface of aligning head, aligning head is freely rotated by sphere finds plane accurately automatically.If bonding press plane is uneven,
The plane of aligning head can rotate automatically to be adjusted to make plane be bonded bonding press plane, due to rotational angle very little, therefore will not
Mandrel is caused to offset, simultaneously because the guide effect of lead, ram pressures can be transmitted vertically, ensure that bearing will not during press fitting
Occur to press inclined phenomenon.
The utility model has the advantages that：The utility model transmission bearing press-loading apparatus utilizes the principle of spherical rotation, adjusts
In mind can be levelling at random with bonding press, solve in the case of bonding press plane injustice, crooked due to mandrel is led
The bearing press mounting of cause is crooked, is sheared with shell inner hole, causes assembly detection noise test failure, and experimental lifetime result reaches
The problem of less than design requirement, bearing press mounting process qualification rate is improved, improve speed changer assembling quality.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
In figure：Aligning first 1, end cap 2, mandrel 3, lead 4.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description：
A kind of transmission bearing press-loading apparatus, it is characterised in that：Including aligning is first 1, end cap 2, mandrel 3, lead 4, adjust
1 is hemisphere in mind, and aligning first 1 is put into mandrel 3, and first 1 sphere of aligning coordinates with the bellmouth in mandrel 3, ensures that sphere is free
Rotate, aligning first 1 and bonding press plane contact, aligning first 1 pass through the connecting mandrel 3 of end cap 2, press fitting transmission case model machine housing axle
When holding, first bearing is put on gear box casing, mandrel 3 by lead 4 insert brearing bore, the alignment bearings inner ring of mandrel 3,
After the faying face of lead 4 and the body of mandrel 3 is contacted positioning with bearing inner race, start press, when bonding press encounters aligning
During first 1 upper plane, aligning first 1 is freely rotated by sphere finds plane accurately automatically.If bonding press plane is uneven, aligning head
1 plane can rotate automatically to be adjusted to make plane be bonded bonding press plane, due to rotational angle very little, therefore will not cause core
Axle 3 is offset, simultaneously because the guide effect of lead 4, ram pressures can be transmitted vertically, ensures that bearing will not occur during press fitting
Press inclined phenomenon.
Above content is to combine specific preferred embodiment further detailed description of the utility model, it is impossible to
Assert that specific implementation of the present utility model is confined to these explanations.For the ordinary skill of the utility model art
For personnel, make some equivalent substitutes or obvious modification without departing from the concept of the premise utility, and performance or
Purposes is identical, then should be considered as belonging to the protection domain that claims that the utility model is submitted determine.
