Abstract

A kind of used by oscillating screen self-aligning roller bearing is made of outer ring, inner ring, asymmetric roller and retainer, and inner ring top is equipped with retainer, and asymmetric roller is installed on retainer, and asymmetric roller top is outer ring；Every retainer bottom is equipped with ramp structure, and the height of ramp structure is 0.4 ~ 0.6 times of retainer thickness, and ramp structure angle is 10 ~ 15 °, and retainer is interior leading type MB aligning roller bearing retainers or outer leading type MB aligning roller bearing retainers.The used by oscillating screen self-aligning roller bearing of the utility model designs one ramp structure of band every retainer bottom, can make lubricating oil（Fat）It is effectively stored between two panels retainer, it is more convenient for the lubrication of Bearing inner, bearing can be made in high speed, vibrated, under the working condition of impact, dry friction does not occur for two panels retainer bottom, substantially increase the service life of retainer, to improve the reliability of service life of the novel vibrating screen bearing, the demand of client is met to the maximum extent.

Description

A kind of used by oscillating screen self-aligning roller bearing

Technical field

The utility model is related to technical field of bearings more particularly to MB self-aligning roller bearings.

Background technology

Self-aligning roller bearing is broadly divided into three kinds by structure at present：CA, MB, CC type, wherein CA, MB type are with brass entity Retainer is in the majority, in being usually used in, large size bearing；CC types are steel plate punched bowl-type retainers, are usually used in middle-size and small-size bearing.

As shown in Figure 1, inner ring 2 is with small rib, no centre rib, CA bearing retainers 5 are integrated CA types self-aligning roller bearing Structure；

MB type self-aligning roller bearings are as shown in Figures 2 and 3, and 2 existing centre rib of inner ring also has small rib, MB bearing retainers For bi-body structure, retainer is divided into point of interior guiding retainer 6 and outer guiding retainer 7.

For CC types self-aligning roller bearing as shown in figure 4, inner ring is without rib, CC bearing retainers 8 are two bowl-type punching press framves.

MB type self-aligning roller bearings, usual roller be divided into again it is symmetrical and asymmetrical, due to unsymmetric structure with Outside, the tangent line of inner ring contact point and roller centre line meet at a bit on bearing axis, as shown in figure 5, allowing for this in this way Airframe bearing can carry out pure rolling, be particularly suitable for vibrating screen and use.But vibrating screen bearing usually makes often due to bad environments Retainer earlier period damage, service life is short, increases cost.

Utility model content

In order to solve the problems, such as that the retainer earlier period damage of used by oscillating screen MB type self-aligning roller bearings, the utility model provide A kind of self-aligning roller bearing structure.

The utility model technical solution used for the above purpose is：A kind of used by oscillating screen self-aligning roller bearing, It is made of outer ring 1, inner ring 2, asymmetric roller 10 and retainer, 2 top of inner ring is equipped with retainer, is installed on retainer asymmetric Roller 10,10 top of asymmetric roller are outer ring 1；Every retainer bottom is equipped with ramp structure 11.

The height of the ramp structure 11 is 0.4 ~ 0.6 times of retainer thickness, and 11 angle of ramp structure is 10 ~ 15 °.

The retainer keeps for 3 or outer leading type MB self-aligning roller bearings of interior leading type MB aligning roller bearing retainers Frame 10.

The used by oscillating screen self-aligning roller bearing of the utility model designs one ramp structure of band, energy every retainer bottom Make lubricating oil（Fat）It is effectively stored between two panels retainer, the lubrication for Bearing inner of being more convenient for, bearing can be made in high speed, shaken Under dynamic, impact working condition, dry friction does not occur for two panels retainer bottom, substantially increases the service life of retainer, from And the reliability of service life of the novel vibrating screen bearing is improved, the demand of client is met to the maximum extent.

Specific implementation mode

The vibrating screen self-aligning roller bearing structure of the utility model is as shown in Figure 6 and Figure 7, is MB types, roller is using non-right Title type, Fig. 6 are interior leading type MB self-aligning roller bearings, and Fig. 7 is outer leading type MB self-aligning roller bearings.Including outer ring 1, inner ring 2, Retainer 3, asymmetric roller 4,2 top of inner ring are equipped with retainer, asymmetric roller 10, asymmetric roller 10 are installed on retainer Top is outer ring 1.Retainer keeps for 3 or outer leading type MB self-aligning roller bearings of interior leading type MB aligning roller bearing retainers Frame 10 processes a special ramp structure 11, ramp height size is about 0.5 times of retainer thickness in the bottom of retainer 3 Degree, ramp angles are about 10 ~ 15 °.

In use, lubricating oil or fat can be by the slopes, into Bearing inner or between being stored in two panels retainer, so i.e. Make bearing under the mal-conditions such as high speed, vibration, two panels retainer bottom is not easy to that dry friction occurs.It is the conventional structure bearing longevity 1.5 times of life or more.It is entirely capable of meeting the bad working environments condition of vibration sieve.
