The utility model provides a light-duty high rotational speed cylinder roller is entity holder for bearing, comprises holder seat (1) and holder lid (2), holder seat (1) and holder lid (2) be split type self-clinching connection, holder seat (1) connect on by the frame circle a plurality of frame roof beam (3) and constitute, the space that encloses between per two adjacent frame roof beams (3) and frame circle, holder lid (2) is the pocket hole of holder, its characterized in that: the outer side of the frame beam (3) is radially provided with a flat-bottom V-shaped groove (4), and the length of the flat-bottom V-shaped groove (4) is greater than 1/3 of the length of the frame beam (3) and less than 1/2 of the length of the frame beam (3).

Technical Field

The invention relates to a solid retainer for a cylindrical roller at a high rotating speed, in particular to a light solid retainer for a high-rotating-speed cylindrical roller bearing.

Background

Solid holders of brass are widely used in the modern bearing industry because of their good high tensile strength and freedom from lubricant, but brass is expensive, especially for cylindrical roller bearings, the volume of the holders occupies almost half of the space, which is particularly expensive, and the heavy holders limit the rotation of the rolling elements, reducing the transmission efficiency of the bearing.

Disclosure of Invention

To overcome the disadvantages of the prior art, the invention aims to provide a solid retainer for a light high-rotating-speed cylindrical roller bearing.

The technical solution of the invention comprises the following steps: the utility model provides a light-duty high rotational speed cylinder roller is entity holder for bearing, comprises holder seat and holder lid, holder seat and holder lid for split type rivet connection certainly, holder seat connect a plurality of frame roof beam by the frame circle and constitute, the space that encloses between per two adjacent frame roof beams and frame circle, the holder lid is the pocket hole of holder, its characterized in that: the outer side of the frame beam is radially provided with a flat-bottom V-shaped groove, and the length of the flat-bottom V-shaped groove is greater than 1/3 of the length of the frame beam and less than 1/2 of the length of the frame beam.

Compared with the prior art, the invention has the following advantages: the cut flat-bottom V-shaped groove 3 effectively reduces the weight of the retainer, reduces the influence caused by inertia when the bearing rotates, and simultaneously reduces the price of the retainer. Meanwhile, the contact area between the cage pocket and the rolling body is reduced by the V-shaped groove, the restraint of the cage on the rolling body is reduced, and the rotation speed of the bearing is improved. The flat-bottomed V-groove is advantageous for guiding the lubricant in the bearing space to the raceway surface, improving bearing lubrication.

Drawings

FIG. 1 is a schematic diagram of an embodiment of the present invention.

Fig. 2 is a schematic perspective view of an embodiment of the present invention.

In the figure: 1. the device comprises a holder seat, 2 a holder cover, 3 a frame beam, 4 a flat-bottom V-shaped groove.

Detailed Description

The embodiments are described below with reference to the accompanying drawings:

retainer seat 1 and retainer lid 2 adopt the processing of brass entity to form, retainer seat 1 and retainer lid 2 are split type and rivet the connection certainly, retainer seat 1 has connect a plurality of frame roof beam 3 by the frame circle to constitute, the space that encloses between every two adjacent frame roof beams 3 and frame circle, retainer lid 2 is the pocket hole of holder, radially be equipped with flat V type groove 4 in the frame roof beam 3 outside, the length of flat V type groove 4 is greater than 1/3 of frame roof beam 3 length, be less than 1/2 of frame roof beam 3 length.

The length of the flat-bottom V-shaped groove is controlled to be between 1/3 and 1/2, so that the weight of the retainer can be reduced, the restraint of two ends of the retainer on the roller can be ensured, and the roller is prevented from transversely rotating.
