Angular contact ball bearing can bear radial load and axial load simultaneously, can work at higher rotational speeds.Contact angle
Bigger, axial carrying capacity is higher.High accuracy and high-speed bearing generally take 15 degree of contact angles, under responsive to axial force, contact angle
It can increase.The angular contact ball bearing of 15 degree of contact angles is with the pnenolic aldehyde bakelite holder in straight pocket hole, is difficult to make outer ring, protect during assembling
Hold frame and steel ball is fixed, pairing set brings very big difficulty, while also influences the product quality after trap.Wherein outer ring fore shaft
Angular contact ball bearing assembly difficulty is bigger.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of contact angle ball bearing fit drawing die of outer ring fore shaft,
The bearing inner race of heating is put into the second cavity, the second cavity inner wall limited bearing inner ring position, retainer is placed on step
Retainer is enclosed on outside bearing inner race simultaneously at end, and required steel ball is pushed into retainer from outside along the inwall of the first cavity
In pocket hole, steel ball side is withstood by bearing inner race, and steel ball opposite side is withstood by the inwall of the first cavity, installed in retainer
The position height of steel ball its centre of sphere in pocket hole is higher than the position height of the first cavity inner wall upper end, and all steel balls are all installed to
Corresponding to retainer in pocket hole after, the outer ring with fore shaft is enclosed on the outside of steel ball and retainer, then pushed outer ring,
Steel ball is set to reach exactly in the raceway groove of outer ring.The assembling of the angular contact ball bearing of outer ring fore shaft that this is practical and convenient, is greatly improved
Trap efficiency, and reduce and damage, improve product quality.
Technical scheme is used by the utility model solves its technical problem：A kind of contact corner-kick of outer ring fore shaft is provided
Bearing fit drawing die, including base and cylinder, the upper center of described base is vertically-mounted cylinder, in the upper surface of the cylinder
Portion is sequentially arranged the first cavity, the second cylindrical cavity from top to bottom, and the first described cavity is in small top and big bottom
It is round table-like, the axis three axis of the axis of first cavity, the axis of the second cavity and cylinder overlaps, and described first is empty
The diameter of chamber upper end is equal to the diameter of cylinder, and the diameter of the first cavity lower end is more than the diameter of the second cavity
The junction of size, the first described cavity and the second cavity forms a circle step.
Supplemented as one kind to technical scheme described in the utility model, described base is cylindrical, the base
Upper center is axial arranged cylinder.
Supplemented as one kind to technical scheme described in the utility model, described cylinder is integrally formed with base.
Beneficial effect：A kind of contact angle ball bearing fit drawing die of outer ring fore shaft is the utility model is related to, the bearing of heating
Inner ring is put into the second cavity, the second cavity inner wall limited bearing inner ring position, retainer is placed on into step upper end while kept
Frame is enclosed on outside bearing inner race, required steel ball is pushed into the pocket hole of retainer from outside along the inwall of the first cavity, steel
Ball side is withstood by bearing inner race, and steel ball opposite side is withstood by the inwall of the first cavity, in retainer pocket hole
The position height of its centre of sphere of steel ball is higher than the position height of the first cavity inner wall upper end, and all steel balls are all installed to retainer pair
After in the pocket hole answered, the outer ring with fore shaft is enclosed on the outside of steel ball and retainer, then pushed outer ring, make steel ball firm
In the raceway groove for reaching outer ring well.The assembling of the angular contact ball bearing of outer ring fore shaft that this is practical and convenient, substantially increase trap effect
Rate, and reduce and damage, improve product quality.

Embodiment
With reference to specific embodiment, the utility model is expanded on further.It should be understood that these embodiments are merely to illustrate this
Utility model rather than limitation the scope of the utility model.In addition, it is to be understood that reading the content of the utility model instruction
Afterwards, those skilled in the art can make various changes or modifications to the utility model, and these equivalent form of values equally fall within this Shen
Please appended claims limited range.
Embodiment of the present utility model is related to a kind of contact angle ball bearing fit drawing die of outer ring fore shaft, as Figure 1-3,
Including base 1 and cylinder 2, the upper center of described base 1 is vertically-mounted cylinder 2, from upper in the middle part of the upper surface of the cylinder 2
The first cavity 3, the second cylindrical cavity 4 are sequentially arranged under, the first described cavity 3 is in small top and big bottom circle
Mesa-shaped, the axis three axis of the axis of first cavity 3, the axis of the second cavity 4 and cylinder 2 overlap, and described first is empty
The diameter of the upper end of chamber 3 is equal to the diameter of cylinder 2, and the diameter of the lower end of the first cavity 3 is more than the second cavity 4
The junction of diameter, the first described cavity 3 and the second cavity 4 forms a circle step 5.
