Abstract

The utility model discloses a novel spherical roller bearing holder, which is installed within the central circle of the bearing roller group. The holder is the overall punched steel plate ring and cone structure. The cross-section of the holder (1) lintel (7) is in the shape of Chinese character gong. Several access holes are provided on the ring cone structure surface of the holder (1). The large end surface of the holder is provided with upside-down edges (6), on which locking points (2) of a locking roller are equipped. Compared with the general spherical roller bearing holder, the holder adopts the structure of large-end upside-down edge and end surface extrusion concave, which enhances the rigidity of holder and contains high level of technology. Thus, the holder meets the requirement of economic applicability, greater bearing capacity and longer useable life.

Description

A kind of novel selfaligning roller bearing retainer

Technical field:

The utility model relates to the technical field of retainer, a kind of novel selfaligning roller bearing retainer.

Background technique:

At present, along with the application of selfaligning roller bearing is day by day extensive, people wish that designed bearing has higher bearing capacity, longer working life, thereby can reduce product size in design, alleviate product weight, save cost, improve power output.The selfaligning roller bearing of common structure as shown in Figure 1, its retainer structure strengthens crossing the restriction of beam width because of relying on lintel lock lock roller, its retainer structure is shown in 2,3 schematic representation; Because be subjected to the restriction that retainer is crossed beam width and lock roller mode, its roller quantity and roller diameter are restricted.Bearing capacity is difficult to be greatly improved, and competition capability is not strong.

Summary of the invention:

Cross the restriction of beam width and lock roller mode for overcoming existing retainer, the problem that roller quantity and roller diameter are restricted and bearing capacity is low, the purpose of this utility model has provided a kind of novel selfaligning roller bearing retainer, use the selfaligning roller bearing of new structure retainer, can satisfy economic serviceability and bigger bearing capacity, the demand of long life more.

For achieving the above object, the utility model adopts following technological scheme:

Described novel selfaligning roller bearing retainer, adopt integrated type steel plate punching press cone structure ringwise, the lintel cross section of retainer is " worker " font, have several fenestras on the annular cone face of retainer, the large end face of retainer is provided with flange, and its flange is provided with the lock point of locking roller.

Described novel selfaligning roller bearing retainer, its lock point is formed by indentation, and its lock point is positioned at the roller recess of roller end face.

Described novel selfaligning roller bearing retainer, the lintel of its retainer is in bearing within the set of rollers center circle.

Owing to adopt aforesaid technological scheme, the utlity model has following superiority:

The lintel of this novel selfaligning roller bearing retainer is within the set of rollers center circle as Fig. 4 in bearing, simultaneously, changes the roller locking mode into roller end face locking by the locking of retainer lintel; Its retainer is just allowed and is put into roller more or that diameter is bigger, and the load-carrying ability of bearing is improved.Satisfying under the identical usability, the boundary dimension of bearing can reduce, and uses the economic benefit of this bearing products just can improve.Retainer forms the lock point by having adopted the indentation of big end flange and large end face, has better assembly process process at roller end face lock roller, has increased the rigidity of retainer, and technology content is higher; Can satisfy economic serviceability and bigger bearing capacity, the demand of long life more.

Adopt the E type selfaligning roller bearing of the utility model retainer structure, bearing capacity improves 30%, and double working life.As the 22224E type selfaligning roller bearing that once designed, rated load is 630000N, and the 22224CC bearing rated load of same model is 466000N.

Embodiment:

As shown in Fig. 4,5,6,7: this novel selfaligning roller bearing retainer, adopt integrated type steel plate punching press cone structure ringwise, lintel (7) cross section of retainer (1) is " worker " font, have several fenestras (4) on the annular cone face of retainer (1), the large end face of retainer is provided with flange (6), and its flange is provided with the lock point (2) of locking roller.Its lock point (2) is formed by indentation, and its lock point (2) is positioned at the roller recess (5) of roller (3) end face.The lintel (7) of its retainer (1) is in bearing within roller (3) the group switching centre circle.

This novel selfaligning roller bearing retainer (1) has a style of one's own, retainer (1) relies on the large end face indentation to form the roller (3) that lock point (2) pins end face band depression, avoided the restriction because of relying on lintel lock roller to strengthen beam width in the past, the lintel of retainer (1) is " worker " font cross section, hold with the CC profile shaft of common retainer and to compare, adopt the E profile shaft of novel retainer to hold, retainer is in bearing within the set of rollers center circle, simultaneously, change the roller locking mode into roller end face locking by the locking of retainer lintel; Like this, retainer is just allowed and is put into roller more or that diameter is bigger, and the load-carrying ability of bearing is improved.Satisfying under the identical usability, the boundary dimension of bearing can reduce, and uses the economic benefit of this bearing products just can improve.
