Description
Technical field
The utility model belongs to technical field of bearing processing, relates generally to a kind of large-scale ultra-thin-wall ball bearing dress ball mould
Tool.
Background technique
So-called large size ultra-thin-wall refers to 200 D≤400 < of outer diameter, and (D is bearing outside diameter to the bearing of (D-d)/2≤B, and d is axis
Internal diameter is held, B is bearing height), bearings has the characteristics that light-weight, wall is thin, sectional dimension is small, is widely used in machine
The fields such as people, aerospace, fine measuring instrument, Medical Instruments, satellite communication, high speed clean energy resource, light electric vehicle；For reality
Existing bearing low friction torque, high rigidity, good rotating accuracy, the steel ball outer diameter used is very small, and number is more, therefore axis
It holds and will appear certain dress ball difficulty in assembly.
Utility model content
The purpose of the utility model is to provide a kind of large-scale ultra-thin-wall ball bearing dress ball molds, can solve product dress
The problem of ball hardly possible, and improve processing efficiency.
Following technical solution can be used to realize in the utility model:
A kind of large size ultra-thin-wall ball bearing dress ball mold, the dress ball mold have die ontology annular in shape,
The internal diameter of the die ontology is less than the internal diameter of installation ball bearing, and the outer diameter of the die ontology is greater than installation ball bearing
Outer diameter；Have on the upper surface of the die ontology to spring bearing rolling element and makes bearing roller positioned inside and outside
The circular arc cylindrical boss of channel center position；The circular arc cylindrical boss is between ball bearing inner race and outer ring；The circle
The width of arc cylindrical boss is less than the width in gap between inner ring and outer ring；The circular arc cylindrical boss is by the upper of die ontology
End face is divided on the inside of mould upper surface and on the outside of mould upper surface, and between the both ends and mould upper surface of circular arc cylindrical boss
It is connected using chamfered transition；Center of arc's diameter of the circular arc cylindrical boss, the pitch diameter with rolling element in bearing finished products
Unanimously, the circular arc that the circular arc cylindrical boss arc length is surrounded by all bearing rollers on required installation ball bearing is long
Degree.
The utility model proposes a kind of large-scale ultra-thin-wall ball bearing dress ball mold, justified using being arranged on die ontology
Arc cylindrical boss keeps steel ball placed on it, is placed exactly in channel center position, it is easy to enter steel ball in channel, complete dress
Ball work；The Mold Making is simple, and the used time is easily operated, has been greatly improved product dress ball efficiency using it.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the structural profile illustration of the utility model.
Fig. 3 is a kind of bearing schematic diagram that need to be assembled.
In figure: 1, die ontology, 2, circular arc cylindrical boss, 3, mould upper surface, 4, on the inside of mould upper surface, 5, on mold
Outer side surface, 6, inner ring, 7, outer ring, 8, rolling element (steel ball), 9, retainer.
Specific embodiment
In conjunction with attached drawing, illustrate specific embodiment of the utility model:
As shown in attached drawing 1,2, and Fig. 3 is combined, a kind of large size ultra-thin-wall ball bearing dress ball mold, the dress ball mold
With die ontology 1 annular in shape, the internal diameter of the die ontology 1 is less than the internal diameter of installation ball bearing, the mould
The outer diameter for having ontology 1 is greater than the outer diameter of installation ball bearing；Have on the upper surface of the die ontology 1 to spring bearing
Rolling element simultaneously makes bearing roller be located at the boss 2 of inside and outside channel center position；The circular arc cylindrical boss 2 is located at ball bearing
Between upper inner ring 6 and outer ring 7；The width of the circular arc cylindrical boss 2 is less than the width in gap between inner ring and outer ring；Described
The upper surface of die ontology is divided into 4 and on the outside of mould upper surface 5 on the inside of mould upper surface by arc boss 2, and circular arc column
It is connected between the both ends and mould upper surface of boss 2 using chamfered transition；Center of arc's diameter of the circular arc cylindrical boss, with
The pitch diameter of steel ball is consistent in bearing finished products, and the circular arc cylindrical boss arc length is all axis on required installation ball bearing
Hold the arc length that rolling element is surrounded.
When filling bearing roller 8, inside and outside circle is drawn to the side for arriving no circular arc boss, in have circular arc cylindrical boss one
While carrying out loading rolling element.Side is packed into steel ball, while dialling ball toward circular arc boss both sides, until steel ball all installs, is at this moment packed into
Steel ball height is placed exactly in inside and outside channel position；Equipped with steel ball one side, inside and outside loop diameter is gently pinched, makes steel ball completely into ditch
In road, and toward steel ball opposite is packed into, a small amount of steel ball is dialled in the channel of no steel ball and is positioned, be easily accomplished dress ball work.
