Description
Technical field
The present invention relates to retainer and machining technology thereof, be specially a kind of centripetal ball bearing wave type retainer and technological method for processing thereof.
Background technique
Centripetal ball bearing wave type retainer is to assemble matching used important technology parts to the bulbus cordis rolling bearing, it plays in bearing rolling element steel ball spaced at equal intervals, prevents from effect that steel ball runs foul of each other and rubs and guiding and drive steel ball to roll on correct raceway.The ball pocket of centripetal ball bearing wave type retainer in the market is common spherical structure, the ball pocket of this kind structure type is bigger with assembling ball surface of contact, cause the bearing operation resistance corresponding bigger, noise in operating is bigger, the heat that rubbed is fast, and, influence the working life of bearing because of the lubriation material that can not store long-time running in the bearing causes the easy wear damage of bearing.Its production technology is: comprise blanking, moulding, shaping, punching, light decorations packaging and other steps, wherein in trimming, utilization is carried out shaping processing greater than the circular steel ball of the bearing assembling steel ball certain size retainer semi-finished product after to moulding, make the semicircle sphere of retainer ball pocket internal surface formation rule, the defective of its existence of retainer of Xing Chenging is like this: use the retainer that the processing method of this technology punching press shaping obtains, ball pocket internal surface is smooth sphere, retainer ball pocket is bigger with assembling ball surface of contact, cause the bearing operation resistance corresponding bigger, noise is bigger during bearing operation, the heat that rubbed is fast, waste energy, and cause bearing wear to damage because of not storing the lubriation material that ensures long-time running in the bearing, because of production technology not science be badly in need of new process.
Summary of the invention
Purpose of the present invention is exactly to provide a kind of centripetal ball bearing wave type retainer and technological method for processing thereof at the defective of above-mentioned existence.The retainer that processing method of the present invention obtains has pit in the ball pocket, ball pocket and bearing assembling ball surface friction drag are little, stores lubriation material abundant, generate heat slow, long service life.
The described pit of the application refers to such an extent that be, in the downward depression that ball pocket internal surface forms, the shape of this depression is indefinite, can be different shape.
The technological scheme of retainer of the present invention is: comprise the ball pocket that is connected by the plane, described ball pocket internal surface has at least one pit.
The characteristics of retainer of the present invention also have: described retainer adopts low carbon steel plate or corrosion resistant plate or copper coin material.The orthographic projection view of described pit is circle, ellipse, rhombus, square or long strip; Described pit is the combination of one or more shapes; Each ball pocket pits total surface area is less than 1/2 of ball pocket internal surface area.
Technological method for processing of the present invention comprises blanking step, forming step, shaping step, punching step, light decorations packaging step, it is characterized in that, described shaping step adopts the shaping steel ball of sphere band projection that ball pocket internal surface is carried out shaping processing.
Wherein, described projection is bonded on the shaping steel ball surface, and described shaping steel ball is a segment; As preferably, described convex shape is circle, ellipse, rhombus, square or long strip.
Beneficial effect of the present invention is: for retainer; on the internal surface of ball pocket, pit is arranged; the ball pocket is in protection, the running of isolation bearing rolling element; reduce area of contact with the assembling ball; can also store and additional bearing lubrication material, reduce the bearing operation resistance, reduce the bearing operation noise; heating is slow, improves bearing working life, energy saving.Described pit can store and additional bearing lubrication material, reduces the area of contact with the assembling ball, reduces the bearing operation resistance, reduces the bearing operation noise, and heating is slow, improves bearing working life, energy saving.For technological method for processing of the present invention, the shaping step is improved, adopt the shaping steel ball of sphere band projection that ball pocket internal surface is carried out shaping processing, make the some quantity pits of formation in the retainer ball pocket with protruding steel ball shaping, be used for storing and additional bearing lubrication material, thereby it is little to have reached the bearing operation resistance, running noise is low, improve bearing working life, the effect of energy saving etc.; Adopt segment as the shaping steel ball, be convenient in the shaping step, fix this shaping steel ball, guarantee quality of processing and accuracy.This shows that retainer of the present invention and technological method for processing thereof possess outstanding substantive distinguishing features and obvious improvement.

Embodiment
Below in conjunction with accompanying drawing technological scheme of the present invention is described in detail.
As can be seen from the figure, retainer of the present utility model comprises the ball pocket 3 that is connected by plane 4, described ball pocket 3 internal surfaces have at least one pit 1, the shape of this pit 1 without limits, can be various shapes, can also be radial ringed groove, as shown in Figure 3, Figure 4 for having the retainer of grooved pit; Fig. 1, Fig. 2 are the circular and oval retainer that mixes for pit; Fig. 5, Fig. 6 are retainer square, that the rhombus mixing is arranged for pit.As long as all drop within the protection domain of the present utility model for playing the depression that stores the lubriation material effect, " pit " of Any shape quantity all should comprise on the retainer ball pocket internal surface.
Retainer of the present invention preferably adopts low carbon steel plate or corrosion resistant plate or copper coin material, perhaps is the retainer of metallic material, adopts this bowl configurations on its ball pocket, and on the basis with metal retainer advantage, its greasy property and working life increase greatly.
As preferably, the orthographic projection view of described pit 1 is circle, ellipse, rhombus, square or long strip, the pit of wherein said long strip orthographic projection view correspondence is specially radial ringed groove, and described pit can also be the combination of one or more shapes, embodies difform advantage.Wherein, each ball pocket pits total surface area satisfies the ball pocket in protection, the running of isolation bearing rolling element less than 1/2 of ball pocket internal surface area, and the space that stores lubriation material fully is provided, and strengthens greasy property to greatest extent.
