Abstract
The utility model relates to a rolling bearing, in particular to an angular contact ball bearing, which comprises an inner ring and an outer ring. A retainer and a steel ball are arranged between the inner ring and the outer ring; and a locking notch of the outer ring is in the shape of a ladder. The angular contact ball bearing mainly has the advantages of small grinding area, low grinding heat and small bearing deformation, improves the machining precision of a bearing ring, and solves the technical problems in the prior art of easy grinding deformation of the ring during the process of machining the bearing, and large deformation of the bearing outside diameter.
Description
Technical field
The utility model relates to a kind of rolling bearing, relates in particular to a kind of angular contact ball bearing.
Background technique
Rolling bearing is a mechanical sector application important foundation part very widely.No matter be aircraft, automobile, boats and ships, lathe, or household electric appliance, IT machine etc., every place that rotation is arranged all be unable to do without bearing.Bearing outer ring is component of bearing, and the main effect of bearing fore shaft is the rigid bearing steel ball, prevents that steel ball from falling down, and avoids influencing the usability of bearing.The fore shaft of present angular contact ball bearing is generally the inclined-plane form, as Chinese patent application: " lubricated type ultra high speed angular contact ball bearing (CN201106634) under a kind of ring ", inner ring, several rolling elements and a retainer by an outer ring, band oil groove and oilhole are formed, outer ring and inner ring all are with the slope, and a cover astragal assembling fore shaft.Though the fore shaft of this structure can prevent effectively that also rolling element from coming off, but in the process of manufacture of reality, the outer ring be easy to generate grinding deformation, the external diameter amount of deformation of bearing exceeds bearing current standard less than the following scope of 0.020mm in the scope of 0.010～0.030mm; Because thereby the fore shaft grinding causes the monolateral amount of deformation of lasso to cause the bearing outside diameter tapering also bigger than normal greatly, thereby influenced the machining accuracy of bearing, measured complexity simultaneously, the adjustment cycle of lathe is long.
Summary of the invention
The utility model has provided mainly that a kind of grinding area is little, the grinding heating value is little, has improved the machining accuracy of bearing ring, the angular contact ball bearing that bearing deformation is little; Solve existing in prior technology bearing lasso in course of working and be easy to generate grinding deformation, the technical problem that the bearing outside diameter amount of deformation is big.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of angular contact ball bearing, comprise inner ring and outer ring, and between inner ring and outer ring, be provided with retainer and steel ball, the fore shaft place of described outer ring is stepped.The fore shaft place design of outer ring is called stairstepping, fore shaft is separated level, thereby make the grinding area diminish, and has reduced the time of grinding, thereby makes the heating value of grinding reduce, and yield rate improves, and the lathe adjustment cycle shortens, and has improved manufacturing efficiency.
As preferably, described fore shaft is divided into two-layer ladder, and internal layer ladder and outer ring raceway join, and outer ladder and bearing face join, the internal diameter that the internal diameter of locating of described internal layer ladder goes out less than outer ladder.The area of fore shaft is limited, fore shaft is separated two-layerly not only can well dwindle the grinding area, has made full use of the space simultaneously.
As more preferably, described internal layer ladder is connected by chamfered transition with outer ladder.The two-layer step structure of fore shaft is by chamfered transition, and it is little to seamlessly transit stress, the working life of having improved bearing.
As more preferably, the area of described internal layer ladder is the 1/4-2/5 of the outer ring stepped shaft gross area.The fore shaft area is equivalent to about 1/3 of whole slope property structural area, thereby grinding deformation is little, and the process-cycle is short.
Therefore, a kind of angular contact ball bearing of the present utility model has following advantage: the fore shaft place is set to stairstepping, greatly reduces the grinding deformation amount in the process of manufacture, has reduced grinding time and lathe adjustment cycle, has improved working efficiency; Stepped design is two-layer and adopts chamfered transition, has reduced stress when having made full use of the space, has improved the working life of bearing.
Description of drawings:
Fig. 1 is the schematic representation of a kind of angular contact ball bearing of the present utility model.
Fig. 2 is Fig. 1 Internal and external cycle schematic representation.
Fig. 3 is the enlarged view at A place in Fig. 2.
The concrete thing mode of implementing:
Below by embodiment, and in conjunction with the accompanying drawings, the technological scheme of model utility is described in further detail.
Embodiment:
Shown in Fig. 1 and 2 and 3, a kind of angular contact ball bearing comprises inner ring 1 and outer ring 2, is provided with steel ball 3 and retainer 4 between inner ring 1 and outer ring 2, and retainer 4 passes steel ball 3 steel ball 3 is fixed between inner ring 1 and the outer ring 2.The fore shaft place of outer ring 2 is a stairstepping, and step-like fore shaft is divided into inside and outside two-layer ladder, and internal layer ladder 5 is near the outer ring raceway 6 of outer ring, and outer ladder 7 is near the end face 8 of bearing.Adopt inclined-plane 9 to connect transition between internal layer ladder 5 and the outer ladder 7, the outer ring internal diameter of internal layer ladder 5 is less than the outer ring internal diameter of outer ladder 7, and the area of internal layer ladder 5 is 1/3 of the outer ring stepped shaft gross area.Adopt the step type locking notch structure, make the grinding area, reduced grinding time and lathe adjustment cycle, make that the external diameter amount of deformation of bearing is little, thereby the bearing outside diameter tapering diminishes also, improved the up-to-standard rate of product only for about 1/3 of original slope shape locking notch structure.
Specific embodiment described herein only is that design of the present utility model is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
