Abstract
A ribbon retainer with an anomalous pocket belongs to the bearing technical field. The utility model aims to solve the technical problems that a ribbon retainer with the anomalous pocket which can ensure that a rolling body gets sufficient lubrication in the moving, and cannot cause the rolling body to be torn. The utility model provides a technical feature that, the middle of a pocket (1) is a spherical zone, the inner and the outer sides of the spherical zone are respectively straight line zones (2), a connection formed respectively by the pocket and a plane by a transitionary chamfer angle (3) is arranged between the two pockets and the plane (4). Because the rolling body is only contacted with the inner and the outer straight line zones of the spherical zone in the pocket, while the middle spherical zone can store lipin, to be used for ensuring that the rolling body is provided with plenitudinous lubricant, thereby effectively solving the technical problem that strong noise is hard to be overcome by the retainer of a spherical pocket or an elliptic pocket for a long time, obviously reducing the decibel value and different sounds of the bearing, and greatly improving the service life of the rolling body.
Description
Technical field:
The utility model relates to a kind of bearing cage, particularly a kind of wave-shaped retainer with special-shaped pocket hole.
Background technique:
At present, the pocket hole of 6000 of domestic production serial bearing wave-shaped retainers all is sphere or elliposoidal basically.The pocket hole shape of this sphere or elliposoidal makes that rolling element can not be by sufficient lubrication in when motion, even can cause the scuffing of rolling element, causes rolling element short working life, the noise height that bearing produces.
Summary of the invention:
Technical problem to be solved in the utility model is: provide a kind of rolling element that can make to obtain sufficient lubrication at the volley, the wave-shaped retainer with special-shaped pocket hole that can not cause rolling element to scratch.
Its technological scheme is: a kind of wave-shaped retainer with special-shaped pocket hole, has the retainer that links to each other successively and constitute by special-shaped pocket hole and plane, it is characterized in that: be spherical zone in the middle of the described pocket hole, the inside and outside both sides of spherical zone are respectively the straight line band, connect and compose retainer by the transition chamfering respectively between two special-shaped pocket holes and the plane.Its technique effect is: because rolling element just contacts with the inside and outside two straight line bands of spherical zone in the pocket hole, middle spherical zone then can store grease, is used for guaranteeing that rolling element has sufficient lubricating.Thereby the retainer that has solved spherical pocket hole or elliposoidal pocket hole effectively is difficult to the technical barrier of the high noisy that overcomes for a long time always, has reduced the decibel value and the different sound of bearing significantly, the working life of having improved rolling element greatly.Through comparative trial, see the following form:
Show that by above-mentioned comparative trial data the wave-shaped retainer in special-shaped pocket of the present invention hole has reached the effect of quiet bearing fully.
Description of drawings:
Fig. 1 is the utility model structural representation;
Fig. 2 is the B--B sectional drawing of Fig. 1;
Fig. 3 is the A--A sectional drawing of Fig. 1.
Embodiment:
As shown in Figure 1 and Figure 2, have the wave-shaped retainer in special-shaped pocket hole, have the wave-shaped retainer that links to each other successively and constitute by pocket hole 1 and plane 4.In the middle of the pocket hole 1 is spherical zone, and the inside and outside both sides of spherical zone are respectively straight line band 2 (see figure 3)s, constitutes being connected of retainer by transition chamfering 3 respectively between two pocket holes and the plane 4.The plane is provided with rivet hole 5, so that by rivet upper and lower two rolling elements that have the wave-shaped retainer in special-shaped pocket hole and be dropped in its pocket hole are linked together.
Claims (2)
1. wave-shaped retainer with special-shaped pocket hole, has the wave-shaped retainer that links to each other successively and constitute by special-shaped pocket hole and plane, it is characterized in that: be spherical zone in the middle of the described pocket hole (1), the inside and outside both sides of spherical zone are respectively straight line band (2), constitute being connected of pocket hole and plane by transition chamfering (3) respectively between two pocket holes and plane (4).
2. a kind of wave-shaped retainer with special-shaped pocket hole according to claim 1 is characterized in that: described plane (4) are provided with rivet hole (5).
