In order to achieve the above purpose, the present utility model adopts the following technical scheme: a low temperature rise cage for a tapered roller bearing of a wind power main shaft, comprising: the novel roller pocket comprises a main body, pockets, rollers and a cross beam, wherein the main body is of an annular structure with conical side walls, the pockets are formed in the main body, the pockets are multiple, the pockets are uniformly formed in the main body, the rollers are arranged in each pocket, the cross beam is arranged between every two adjacent pockets, and the cross beam is used for separating the rollers.
The crossbeam wholly be transversely set up and its both sides have isosceles trapezoid structure of recess, the crossbeam includes: the device comprises a cross beam, two convex sections A, two concave sections and two convex sections B, wherein the convex sections A, the concave sections and the convex sections B are symmetrically arranged on two side walls of the cross beam, the convex sections A are arranged at the bottoms of two sides of the cross beam, the convex sections A are connected with one ends of the concave sections, the other ends of the concave sections are connected with the convex sections B, and the convex sections B are arranged on the upper parts of two sides of the cross beam; the convex section A and the convex section B are in contact fit with the roller.
The lengths of the convex section A, the concave section and the convex section B are L1, L2 and L3 respectively; the length ratio of each section is as follows: L1:L2:L3=1:2 to 3:1.
The beneficial effects of the utility model are as follows: in the operation process of the retainer, the lubricant can flow through the inside of the pocket to take away heat, so that friction heating in the operation process of the bearing is effectively reduced, the condition that the bearing fails due to roller burn is prevented, and the service life of the bearing is prolonged.
Drawings
FIG. 1 is a schematic diagram of the structure of the present utility model.
Fig. 2 is a partial schematic view at a of fig. 1.
In the figure: 1. the main body comprises 2 parts of pockets, 3 parts of cross beams, 301 parts of convex sections A,302 parts of concave sections, 303 parts of convex sections B,4 parts of concave sections and rollers.
Description of the embodiments
The following description of the embodiments of the present utility model will be made clearly and fully with reference to the accompanying drawings, in which it is to be noted that the embodiments described are merely some, but not all embodiments of the present utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1-2, a low temperature rise cage for a tapered roller bearing of a wind power main shaft includes: the novel roller pocket comprises a main body 1, pockets 2, rollers 4 and a cross beam 3, wherein the main body 1 is of an annular structure with conical side walls, the pockets 2 are arranged on the main body 1, the pockets 2 are multiple, the pockets 2 are uniformly arranged on the main body 1, the rollers 4 are arranged in each pocket 2, the cross beam 3 is arranged between every two adjacent pockets 2, and the cross beam 3 is used for separating the rollers 4. The whole isosceles trapezoid structure that transversely sets up its both sides and have the recess of crossbeam 3, crossbeam 3 includes: the device comprises a beam 3, convex sections A301, concave sections 302 and convex sections B303, wherein the number of the convex sections A301, the concave sections 302 and the convex sections B303 is two, the convex sections A301, the concave sections 302 and the convex sections B303 are symmetrically arranged on two side walls of the beam 3, the convex sections A301 are arranged at the bottoms of two sides of the beam 3, the convex sections A301 are connected with one ends of the concave sections 302, the other ends of the concave sections 302 are connected with the convex sections B303, and the convex sections B303 are arranged at the upper parts of two sides of the beam 3; the convex section A301 and the convex section B303 are matched with the roller 4 in a contact way.
