Abstract
The invention relates to a two-raceway two-direction angular contact bearing comprising an outer ring and inner rings sleeved in the outer ring. Roll balls are arranged among the outer ring and the inner rings, two inner rings sleeved in the outer ring are provided, raceways are respectively arranged among the two inner rings and the outer ring, the roll balls are arranged in the raceways, and retainers are arranged among the roll balls. One inner ring and the roll balls in the internal raceway rotate along with a rotation shaft, the other inner ring and the roll balls in the internal raceway rotate along with the other rotation shaft, and the roll balls between the two inner rings are separated by respective retainers, so that normal rotation of the roll balls is guaranteed.
Description
Technical field
The present invention relates to a kind of bearing, the angular contact bearing that especially a kind of pair of raceway can two-way clockwise and anticlockwise.
Background technique
General bearing axle general and one-way rotation cooperates, and can only rotate in one direction, and can not carry out clockwise and anticlockwise or two rotatingshafts are rotated with different speed at both direction simultaneously.
Summary of the invention
The present invention proposes a kind of pair of two-way angular contact bearing of raceway, can realize the two-way rotation of two rotatingshafts, and the two-way angular contact bearing of this pair raceway comprises the outer ring and is placed in the inner ring in the said outer ring, between said outer ring and inner ring, is provided with ball; The said inner ring that is placed in the said outer ring is two, offers raceway respectively between said two inner rings and the outer ring, is provided with ball in the said raceway; Be provided with retainer between the said ball.
Preferably, said retainer is two, and the cross section of said retainer one end end face is an annulus, and the other end end face offers some pockets hole; Said two retainers offer an end in pocket hole respectively towards said ball, and said pocket escutcheon is on said ball, and the other end of said two retainers is oppositely arranged.
During rotation, the ball of inner ring and internal raceways thereof rotates with a rotatingshaft, and the ball of another inner ring and internal raceways thereof rotates with another rotatingshaft, and the ball between two inner rings separated by separately retainer, has guaranteed the normal rotation of ball.
The two ends of the of the present invention pair of two-way angular contact bearing of raceway also are provided with seal ring, and the sealing circle is arranged in the inboard draw-in groove in two ends, said outer ring, have guaranteed inner sealing and the cleanliness of bearing, have reduced rate of fault.
The present invention can be used for transmitting two rotatingshafts of different rotating speeds, and simple for structure, rate of fault is low.
Description of drawings
Accompanying drawing 2 is the disassemblying structure schematic representation of the preferred embodiment of the present invention;
Accompanying drawing 3 is the retainer structural representation of the preferred embodiment of the present invention;
Label declaration: outer ring 1, inner ring 21,22, ball 31,32, retainer 41,42, pocket hole 421, seal ring 5.
Embodiment
Preferred embodiment as depicted in figs. 1 and 2, the of the present invention pair of two-way angular contact bearing of raceway comprises outer ring 1 and the inner ring 21,22 that is placed in the said outer ring 1, this inner ring is two independently inner rings that separate.Between outer ring 1 and inner ring 21, and be respectively arranged with ball 31 and ball 32 between outer ring 1 and the inner ring 22, between two inner rings 31,32 and outer ring 1, offer raceway respectively simultaneously, be respectively arranged with ball 31,32 in the described raceway.
Between ball 31 and ball 32, be provided with retainer, this retainer is divided into retainer 41 and retainer 42, covers on respectively on ball 31 and the ball 32.Retainer 41 is identical with the structure of retainer 42, and symmetry is placed.
Be the structure of example explanation retainer below with retainer 42.As shown in Figure 3, the cross section of an end end face of retainer 42 is an annulus, i.e. the back side among the figure; The other end end face offers some pockets hole 421, promptly illustrated front.Retainer 42 offers an end in pocket hole 421 towards ball 32, and pocket hole 421 covers on the ball 32.As shown in Figure 1, the back side of two retainers is oppositely arranged, and the difference in pocket hole in the opposite direction.
As shown in Figure 2, in this preferred embodiment, ball is two rows, is arranged at respectively in two raceways, and every row's ball is nine; Corresponding setting has nine pocket holes on retainer 41 and the retainer 42.
As shown in Figure 1; There is the step of a convexity at the inwall middle part of outer ring 1; The both sides of said step offer outer ring raceway, and offer corresponding inner ring raceway on the interior ring outer wall of said outer ring raceway relative position, and ball 31 and ball 32 roll between said outer ring raceway and inner ring raceway.Simultaneously, as shown in figures 1 and 3, retainer 41,42 offers an end radius in pocket hole greater than the other end radius, so that retainer can not bump and rub with this protruding step.
During rotation; The ball 31 of inner ring 21 and internal raceways thereof can rotate with a rotatingshaft; The ball 32 of another inner ring 22 and internal raceways thereof rotates with another rotatingshaft; And two inner rings 21, the balls between 22 are separated by retainer 41,42 separately, have guaranteed the normal rotation of ball 31,32.
The two ends of the two-way angular contact bearing of this pair raceway also are provided with seal ring 5, and sealing circle 5 is arranged in the inboard draw-in groove in 1 two ends, outer ring, have guaranteed inner sealing and the cleanliness of bearing, have reduced rate of fault.In this preferred embodiment, seal ring 5 is the nitrile rubber seal ring.
Last institute should be noted that; Above embodiment is only in order to technological scheme of the present invention to be described but not to the restriction of protection domain of the present invention; Although the present invention has been done detailed description with reference to preferred embodiment; Those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement technological scheme of the present invention, and do not break away from the essence and the scope of technological scheme of the present invention.
