Description
Technical field
The utility model relates to technical field of bearings, is specifically deep groove ball bearing, more precisely deep groove ball bearing retainer.
Background technique
Existing conventional deep groove ball bearing retainer generally adopts shape wave punching press retainer or nylon cages.
Nylon cages is lightweight, price is low, can adapt to the occasion that rotating speed is very high, but its thickness is comparatively large, needs bearing to have larger inner space, when particularly bearing belongs to special narrow special thin, bearing outside diameter is comparatively large, narrower in width, and steel ball is very little accordingly, the space leaving nylon retainer for is just very little, and retainer thickness is crossed small intensity and is just difficult to ensure.Although shape wave punching press retainer intensity can meet the demands, require also not high to bearing interior space, but shape wave punching press retainer is consisted of rivet two halves retainer, two halves retainer needs to pass through rivet, rivet is too little, and riveted joint is got up very inconvenient, inefficiency, be difficult to control to riveting quality, be difficult to find riveted joint defect.
Summary of the invention
The present utility model object: for overcoming the defect that prior art exists, the utility model provides a kind of easy to process, thickness is thin, the assembly space needed is less, convenient installation, the good overall punching type deep groove ball bearing retainer of intensity, is specially adapted to the bearing series that the inner spaces such as special thin spy is narrow are very little.
For achieving the above object, the utility model provides following technological scheme: a kind of overall punching type deep groove ball bearing retainer, include annular retainer body, annular retainer body is provided with some pocket holes, and be positioned at the steel ball fore shaft of pocket hole upper end open, it is characterized in that: described annular retainer body comprises the integral annular tubular thin plate that steel plate is made, described pocket hole is radially punching press formation in the peripheral wall of annular tubular thin plate, and in the peripheral wall of annular tubular thin plate, radially stamp out the described steel ball fore shaft being positioned at pocket hole upper end open, pocket hole upper end open runs through the axial tip edge of described annular tubular thin plate through steel ball fore shaft.
By adopting technique scheme, annular tubular sheet metal stamping out corresponding pocket hole and steel ball fore shaft formation retainer, processes simple and convenient, armor plate strength is larger, and this retainer thickness is thin, assembly space is little, is specially adapted to the bearing series that the inner spaces such as special thin spy is narrow are very little.
The utility model is set to further: described annular tubular thin plate bottom is provided with circular bottom part flange integrated with it, and circular bottom part flange is formed and annularly tubular thin plate radial direction extension towards annular tubular thin plate internal side diameter upset.
By adopting technique scheme, annular tubular thin plate bottom is one-body molded circular bottom part flange, plays reinforing function, improves the working strength of retainer.
The utility model is set to further: have the arc-shaped corners portion formed through punching press between described circular bottom part flange and annular tubular thin plate, circular bottom part flange is connected through arc-shaped corners portion with annular tubular thin plate, near described arc-shaped corners portion bottom pocket hole.
By adopting technique scheme, effectively eliminating the stress of circular bottom part flange and annular tubular thin plate joint, improving deep groove ball bearing retainer bulk strength.
The utility model is set to further: described steel ball fore shaft is provided with lead-in curve between the axial tip edge in one end and annular tubular thin plate deviating from pocket hole, lead-in curve is indent circular arc, be formed with elasticity lock bridge between the upper end open in then adjacent pocket hole, lead-in curve is positioned on the end face of elasticity lock bridge circumferencial direction.
By adopting technique scheme, in steel ball fore shaft front, also lead-in curve being set, being convenient to elasticity and strutting steel ball fore shaft, be convenient to steel ball and load pocket hole.
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing explanation
Fig. 1 is the utility model specific embodiment overall punching type deep groove ball bearing retainer structural representation;
Fig. 2 is the sectional view along the cutting of A-A line in Fig. 1;
Fig. 3 is part B partial enlarged view in Fig. 2;
Fig. 4 is C part partial enlarged view in Fig. 2.
Embodiment
As shown in Fig. 1 ~ 4, a kind of overall punching type deep groove ball bearing retainer disclosed in the utility model, include annular retainer body 1, annular retainer body 1 is provided with some pocket holes 2, and be positioned at the steel ball fore shaft 3 of pocket hole 2 upper end open, described annular retainer body 1 comprises the integral annular tubular thin plate 11 that steel plate is made, and be positioned at annular tubular thin plate 11 bottom and circular bottom part flange 12 integrated with annular tubular thin plate 11, circular bottom part flange 12 is formed and annularly tubular thin plate 11 radial direction extension towards annular tubular thin plate 11 internal side diameter upset, described pocket hole 2 is radially punching press formation in the peripheral wall of annular tubular thin plate 11, and in the peripheral wall of annular tubular thin plate 11, radially stamp out the described steel ball fore shaft 3 being positioned at pocket hole 2 upper end open, pocket hole 2 upper end open runs through the axial tip edge of described annular tubular thin plate 11 through steel ball fore shaft 3.Add man-hour, first go out ring, then circular bottom part flange is gone out, corresponding and circular bottom part flange attachment portion is described annular tubular thin plate, finally on annular tubular thin plate, once stamps out corresponding pocket hole and steel ball fore shaft, processes simple and convenient, armor plate strength is larger, and this retainer thickness is thin, assembly space is little, is specially adapted to the bearing series that the inner spaces such as special thin spy is narrow are very little; And be combined with circular bottom part flange, improve the intensity of deep-groove ball retainer further, due to the existence of circular bottom part flange, annular tubular thin plate and circular bottom part flange thickness can accomplish 0.2mm, reach more frivolous.
Wherein, there is between described circular bottom part flange 12 and annular tubular thin plate 11 the arc-shaped corners portion 13 formed through punching press, circular bottom part flange 12 is connected through arc-shaped corners portion 13 with annular tubular thin plate 11, near described arc-shaped corners portion 13 bottom pocket hole 2.The stress of effective elimination circular bottom part flange and annular tubular thin plate joint, improves deep groove ball bearing retainer bulk strength.
In this specific embodiment, described steel ball fore shaft 3 is provided with lead-in curve 14 towards deviating between the one end in pocket hole 2 and the axial tip edge of annular tubular thin plate 11, lead-in curve 14 is indent circular arc, be formed with elasticity lock bridge 15 between the upper end open in then adjacent pocket hole 2, lead-in curve 14 is positioned on the end face of elasticity lock bridge 15 circumferencial direction.In steel ball fore shaft front, also lead-in curve is set, is convenient to elasticity and struts steel ball fore shaft, be convenient to steel ball and load pocket hole.
