Has the advantages of reducing friction force, increasing lubrication and heat dissipation, and the like.)

1. The utility model provides a low friction moment tapered roller bearing holder, includes that circle (1), big circle (5), corbel (3), pocket hole (2), its characterized in that: a plurality of branch beams (3) are uniformly fixed between the small circle (1) and the large circle (5), the pocket holes (2) are located between two adjacent branch beams (3), and notches (4) are respectively arranged at the upper end and the lower end of the two sides of each branch beam (3).

2. A low friction torque tapered roller bearing cage according to claim 1, wherein: the middle part of the small ring (1)) at the upper end of the pocket (2) is provided with a small ring gap (6).

Technical Field

The invention relates to a tapered roller bearing retainer, in particular to a tapered roller bearing retainer with low friction torque.

Background

The pocket of the existing standard tapered roller bearing retainer is in an isosceles trapezoid shape, and the support beam and the rolling body are in overall line contact.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provide a low-friction-torque tapered roller bearing retainer which reduces friction torque, reduces friction area and improves lubrication and heat dissipation.

The technical solution of the invention comprises the following steps: the utility model provides a low friction moment tapered roller bearing holder, includes circle, big circle, a back beam, pocket hole, its characterized in that: a plurality of support beams are uniformly fixed between the small circle and the large circle, the pocket holes are located between two adjacent support beams, and notches are respectively arranged at the upper ends and the lower ends of the two sides of each support beam.

The middle of the small ring at the upper end of the pocket hole is provided with a small ring gap.

Compared with the prior art, the invention has the following advantages:

1. the contact area between the rolling body and the retainer is reduced, and the friction force is reduced.

2. The notched portions may provide increased lubrication and heat dissipation.

Drawings

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

Fig. 2 is a schematic view of a conventional tapered roller bearing cage.

In the figure: 1. the small circle, 2, pocket, 3, support beam, 4, gap, 5, big circle, 6, small circle gap.

Detailed Description

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

a low-friction torque tapered roller bearing retainer is formed by integrally processing a small ring 1, a large ring 5 and a supporting beam 3, wherein gaps 4 are respectively arranged at the upper end and the lower end of the two sides of the supporting beam 3, and the gaps 4 of the retainer are partially in arc transition to ensure the strength of the supporting beam 3, and the design of the gaps 4 reduces the contact field of the supporting beam 3 and a rolling body of the retainer. The normal work of rolling element is guaranteed in the field that the back-up beam 3 and roller contact, and breach 4 part can also be stored partly lubricating grease (oil), reaches even lubrication and is convenient for the bearing heat dissipation simultaneously the pocket 2 upper end 1 middle part of circling be equipped with the circling breach 6, do benefit to the loading and unloading of roller.

The contact parts of the retainer and the rolling body are always positioned at two sides of the center of the rolling body, so that the rolling body cannot be transversely moved in the rotating process.
