Abstract
The invention discloses a metal solid cage used for the large/super thin-wall light-load cylindrical roller bearing, which is composed of a beam (5), a roller pocket (3) and a weight-loosing pocket (4). The roller pocket (3) and the weight-loosing pocket (4) are respectively arranged on the beam (5). The invention is characterized in that a weight-losing pocket which holds no roller is deigned to lose the weight and improve the rotation speed. The invention is light in structure and has the advantages of high efficiency, high speed, and high precision, low cost, high performance and is energy-saving and is very suitable to be used in the large/super thin-wall cylindrical roller bearing which has low load bearing, high rotation speed and high precision. The assembled bearing has high precision, high speed, low vibration noise, stable operation performance and has good service life.
Description
Technical field
The present invention relates to field of bearings, relate generally to a kind of large-scale, super-huge thin-walled underloading roller bearing metal solid holding frame structural design.
Background technique
The application of large-scale/especially large (outside dimension is more than 440mm) thin-wall bearing at present more and more widely under the condition that satisfies equipment precision, bearing capacity, uses the thin-wall bearing can conserve space, and energy saving reduces raw materials consumption.But the thin wall cylindrical roller bearing mainly contains two kinds with the solid cage design by the traditional design mode: 1, the cylindrical straight pocket hole retainer shown in accompanying drawing 1,2; 2, the retainer of riveted joint certainly shown in accompanying drawing 3,4.Its form all is the two halves solid cage, and pocket hole 1 unanimity of retainer, be evenly distributed on the beam 2, and uniform fill roller after, with rivet or certainly the riveted joint finish.These two kinds of retainers all are suitable for large-scale, the extra large size bearing of the light thin wall that speed is moderate, precision is general, and for highi degree of accuracy, high-revolving large-scale/especially large light thin wall underloading roller bearing is not best.
Summary of the invention
The purpose of this invention is to provide a kind of new structure large-scale/especially large thin-walled underloading roller bearing metal solid holding frame, this retainer structure is slim and graceful, and it is lower to be suitable for very much carrying, and rotating speed is faster on the thin-walled lightweight product.
Purpose of the present invention can adopt following technological scheme to realize: it is made of beam and pocket hole, the pocket hole is made of the roller pocket hole and the loss of weight pocket hole that are used to adorn roller, loss of weight pocket bore dia can be greater than roller pocket bore dia, also can be consistent with roller pocket bore dia, and loss of weight pocket hole number can be consistent with roller pocket hole number, and also comparable roller pocket hole number reduces at double.Roller pocket hole and loss of weight pocket hole are distributed on the beam respectively.Roller pocket hole and loss of weight pocket hole are cylindrical pocket hole.
Characteristics of the present invention are that design has loss of weight pocket hole, the roller of not packing into, and purpose is weight reduction, and it is thinner because of its wall thickness to improve rotating speed, and materials are less also to have characteristics such as low cost, high-performance.Loss of weight pocket bore dia can be greater than roller pocket bore dia, also can be consistent with roller pocket bore dia, or less than the pocket bore dia, and loss of weight pocket hole number can be consistent with roller pocket hole number, and also comparable roller pocket hole number reduces at double.Characteristics of the present invention are to have broken retainer pocket hole Design Mode in the past, and the pocket bore dia is designed to the structure that differs in size as required, have emphasized that the pocket hole not only is used to adorn the effect that rolling element also can be used for loss of weight.This retainer structure is slim and graceful flexibly, have efficiently, at a high speed, characteristics such as highi degree of accuracy, low cost, saving resource, high-performance, be suitable for very much carrying in large-scale, the super-huge thin wall cylindrical roller bearing low, that rotating speed is high, precision is high.Bearing accuracy height after the assembling, speed is fast, vibrating noise is low, fortune dress steadily, arranged good working life.

Embodiment
In conjunction with the accompanying drawings, specific embodiments of the invention are described.
Shown in accompanying drawing 5,6,7,8: the present invention is made of beam 5 and pocket hole, the pocket hole is made of the loss of weight pocket hole 4 that is used to adorn the roller pocket hole 3 of roller and be used for weight reduction, roller pocket hole 3 and loss of weight pocket hole 4 are distributed on respectively on the beam 5, and roller pocket hole (3) and loss of weight pocket hole (4) are cylindrical pocket hole.Loss of weight pocket hole 4 diameters can be greater than roller pocket hole 3 diameters, also can be consistent with roller pocket hole 3 diameters, also can be less than the diameter in roller pocket hole 3, and loss of weight pocket hole 4 diameters of present embodiment can be greater than roller pocket hole 3 diameters.
Loss of weight pocket hole (4) number can be consistent with roller pocket hole (3) number, and also comparable roller pocket hole (3) number becomes multiple to reduce (roller pocket hole (3) number is the multiple in loss of weight pocket hole (4)).Loss of weight pocket hole (4) number of present embodiment can be consistent with roller pocket hole (3) number, between the two every being distributed on the beam (5).
