Embodiment
In Figure 10 and Figure 11, the agent structure of this bearing comprises outer ring 1, inner ring 2, retainer 7, and two row steel balls 4 between Internal and external cycle are set, and is provided with seal ring 8 in the both sides of bearing race, and steel ball 4 is arranged in retainer 7.Be described in detail respectively below:
Inner ring and outer ring, above-mentioned outer ring 1 must design and produce into symmetrically arranged double channel with inner ring 2 and outer ring channel is greater than inner ring ditch apart from c apart from b, forms and does not wait ditch apart from design, inserts after steel ball is installed and forms diagram α wrapping angle, as Figure 10.Particularly, for ease of describing, the arcuate furrow on outer ring and inner ring is labeled as respectively to the first arcuate furrow 5 and the second arcuate furrow 6, such two arcuate furrows are oppositely arranged and form the cavity that holds two row steel balls.Wherein the shoulder block of the first arcuate furrow 5 is positioned at middle part, outer ring, and the shoulder block in the first arcuate furrow outside is less than the shoulder block of inner side.The bottom land of two second arcuate furrows 6 connects mutually and shoulder block is positioned at the outside of the second arcuate furrow, and non-shoulder inside inner ring two second arcuate furrows.Be respectively equipped with the circular arc cutaway 3 of holding steel ball turnover at a side arcuate furrow outer blocking shoulder place of described inside and outside circle, the setting of this breach is to be convenient to load steel ball.And be provided with seal groove at the raceway place of bearing both sides, be convenient to install seal ring 8.
On the outer ring surface of the inner ring surface of above-mentioned bearing outer ring 1 and bearing inner race 2, offer respectively two arc grooves that two row hold the ditch distance such as or not steel ball 4, and in inside and outside circle two arc grooves, outer blocking shoulder height differs, and the outer blocking shoulder of a side is wherein processed to a circular arc cutaway is in order conveniently to pack more steel ball into, bearing load carrying capacity is strengthened.Common double-row-ball angular contact ball bearing cannot be accomplished this point.
Retainer, retainer 7 be the steel plate of uniform thickness through pressing and bending technological forming, first utilize punching equipment to stamp out a sheet steel disc as shown in figure 12, then carry out the appearance of bending formation as shown in Figure 13, Figure 14.Particularly, this retainer can be divided in refinement: ring part 71 and supporting post 72, and wherein supporting post comprises again the inside and outside supporting post that is oppositely arranged on outside in ring part, two daggers of being disbursed from the cost and expenses are evenly distributed on ring part circumferentially to form the U-shaped pocket hole 73 that holds steel ball.
When installation, in the space between two row steel balls that described in two, the ring part 71 of retainer leans on each other mutually and U-shaped pocket hole 73 open surfaces outside.Because pocket hole does not take raceway space without thickness of slab outwardly, this unique design.Simultaneously form point and contact respectively with between ring part, inside and outside supporting post and first, second arcuate furrow at steel ball, totally 5 contacts can catch steel ball, and then control the displacement amount between retainer and steel ball, guarantee the bootstrap of steel ball, reduce friction, wearing and tearing, be easy to fill ball and seal ring is set.And, can be large as far as possible when bearing two ditch position in design choose sphere gap a, increase bearing capacity and the antidumping moment of bearing, be easy to again arrange sealing configuration, more meet the usage requirement of hydraulic press bearing.
Compare, the crown cage setting shown in Fig. 1 to 7, dress ball is few, and bearing load is little, all can not meet bearing load and the usage requirement of antidumping moment.
In Fig. 8, Fig. 9, S shape retainer arranges, and pocket hole inside and outside wall thickness takes up room, dress seal ring difficulty.
Retainer setting in Figure 10, Figure 11, does not take up room without wall thickness (open design) outside pocket hole, and dress seal ring is easy.And steel ball is 5 some contact designs in pocket hole, and not only retainer is lightweight, is also conducive to high rotating speed.Above-mentioned retainer adopts U-shaped punching press iron retainer, and two retainer bottom surfaces are leaned on mutually when mounted, outward opening, this unique design is not only beneficial to fills out ball and dress seal ring, the bootstrap, lubricated and clean that guarantees steel ball, has reduced friction, wearing and tearing, has also just extended the working life of bearing.
Use an assembly method for the double-row angular contact bal bearing of above-mentioned U-shaped retainer,
The first step, by in back-to-back U-shaped retainer space of being inserted between the inside and outside circle of double ditch that play tests, must be by jagged inside and outside circle end to being placed down on fitter's bench face, then left hand is mentioned inner ring to certain altitude, the right hand is inserted the steel ball that meets play in each pocket hole of the U-shaped retainer between inner ring and outer ring, put down the inside and outside circle of inner sleeve integrated overturn and upper end steel ball and retainer, make jagged end upwards;
Second step, rotate inside and outside circle and make its breach positive alignment U-shaped retainer pocket hole, the steel ball that meets play is inserted in U-shaped retainer pocket hole and raceway groove from filling slot, rotate again U-shaped retainer make next pocket hole also the inside and outside circle breach of positive alignment insert again a steel ball in pocket hole and raceway groove, so circulation, until fail to lay down steel ball;
The 3rd step, set and mix up heter temperature and heating time, the semi-finished product bearing of not filling ball is moved to and in the heating ring of having selected, heats jagged position, outer ring, having heated rear rotation U-shaped retainer makes the inside and outside circle breach of a pocket hole positive alignment and inserts a steel ball that meets play in pocket hole and raceway groove, so circulation, until residue pocket hole is all filled up after steel ball, take out bearing, just complete the dress ball process of a set of bearing.
Embodiment recited above is described preferred implementation of the present utility model; not scope of the present utility model is limited; do not departing under the prerequisite of the utility model design spirit; relevant technical staff in the field, to various distortion of the present utility model and improvement, all should expand in protection domain as determined in the utility model claims.
