Abstract
The invention provides a retainer locking opening structure for a cylindrical roller bearing metal entity. A plurality of openings are uniformly distributed in a metal retainer of a cylindrical roller bearing in a circumference direction, a spherical concave gravure is embossed on an opening beam between each two openings, and the diameter of each spherical concave gravure is the same and is smaller than the width of each opening beam; corresponding bosses are arranged on two opposite sides of the interior of each opening, and the distance between every two bosses is 0.8-0.93 times of the aperture of each opening. According to the spherical concave gravure structure, the situations of stress micro-cracks and non-uniformity of metal accumulation are effectively avoided so as to greatly ensure the dynamic balance of the retainer and largely prolong the service of the retainer; the whole structure is simple, and all structures can be easily produced, so that the negative effects on the dynamic balance and the service life of the holder caused by large machining difficulty, difficulty in precision guarantee and the like are avoided.
Description
Technical field
The present invention relates to a kind of roller bearing metal solid holding frame locking notch structure, particularly a kind of for ensureing the locking notch structure not falling roller after retainer internal diameter or external diameter assemble, belong to field of machining.
Background technique
Inner ring or outer ring are without the roller bearing of rib (telescopic) structural type, to guarantee that in assembling roller is not deviate from from retainer fenestra or is scattered, the structural formula of usual employing is on the equally distributed some fenestra beams of retainer, dig out reserved projection in groove or processing, the mode of raggle can make the fine stress crack of retainer surface generation, metal accumulation uneven, drastically influence retainer dynamic balancing and life-span, and the mode of reserved protruding structure, difficulty of processing is large, precision is difficult to ensure, also makes retainer dynamic balancing seriously influenced.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of roller bearing metal solid holding frame locking notch structure, the generation of this roller bearing metal solid holding frame locking notch structure by adopting the structure of round ball-and-socket gravure to effectively prevent crackle, and easy to implement, be convenient to control size.
The present invention is achieved by the following technical programs.
A kind of roller bearing metal solid holding frame locking notch structure provided by the invention, multiple fenestra is evenly distributed with along the circumferential direction at the metal cage of roller bearing, fenestra beam between every two fenestras impresses the ball gravure having ball-shaped recessed, the diameter of each ball gravure is identical and be less than the width of fenestra beam; In each fenestra, both sides are provided with boss corresponding to position relatively, and the spacing of two corresponding boss is 0.8 ~ 0.93 times of fenestra bore.
Between the diameter of described ball gravure is 0.07 ~ 0.20 times of described fenestra bore.
The setting of described boss with the center-diameter of fenestra for symmetry axis.
Distance between two boss of described correspondence is 0.91 times of fenestra bore, and error is ± 5 ‰.
The diameter of described ball gravure is 0.1 times of described fenestra bore, and error is ± 5 ‰.
Beneficial effect of the present invention is: 1. the structure of round ball-and-socket gravure makes the uneven situation of fine stress crack, metal accumulation effectively be avoided, thus ensure that retainer dynamic balancing greatly, well extends the life-span of retainer; 2. overall structure is simple, and all structures can be produced very easily, thus avoid the negative effect that the problems such as difficulty of processing is large, precision Customers ' Legal Right are brought to retainer dynamic balancing and life-span.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the side view of Fig. 1;
In figure: 1-fenestra beam, 11-ball gravure, 12-boss, 2-fenestra.
Embodiment
Further describe technological scheme of the present invention below, but described in claimed scope is not limited to.
A kind of roller bearing metal solid holding frame locking notch structure as shown in Figure 1 and Figure 2, multiple fenestra 2 is evenly distributed with along the circumferential direction at the metal cage of roller bearing, fenestra beam 1 between every two fenestras 2 impresses the ball gravure 11 having ball-shaped recessed, the diameter of each ball gravure 11 is identical and be less than the width of fenestra beam 1; In each fenestra 2, both sides are provided with boss corresponding to position 12 relatively, and the spacing of two corresponding boss 12 is 0.8 ~ 0.93 times of fenestra 2 bore.
Arrange thus, effectively can avoid the generation of fine stress crack, and on lathe, can turn pressure with round end bull stick for ball gravure 11 and draw, difficulty of processing is extremely low, and precision is also secure.
For ensureing the restriction effect of ball gravure 11 pairs of rollers in fenestra, between the diameter of described ball gravure 11 is 0.07 ~ 0.20 times of described fenestra 2 bore.
Unaffected for ensureing retainer dynamic balancing, the setting of described boss 12 with the center-diameter of fenestra 2 for symmetry axis.
As the optimal selection of the distance between two boss 12, the distance between two boss 12 of described correspondence is 0.91 times of fenestra 2 bore, and error is ± 5 ‰.
As the optimum scheme of the diameter of ball gravure 11, the diameter of described ball gravure 11 is 0.1 times of described fenestra 2 bore, and error is ± 5 ‰.
