Abstract

The utility model relates to a vibrating screen bearing, particularly to a vibrating screen self-aligning bearing, and belongs to the field of bearings. Compared with the prior art, the vibrating screen self-aligning bearing has the following outstanding advantages and benefits: through the adoption of an external rolling path and roller double-guidance holding rack, the damage of locking and sintering to the bearing due to the stuck holding rack and rolling body under the impact load is greatly reduced under the guidance of the external rolling path; and the rolling body and the holding rack can not be stuck for some dust going into the rolling body and the holding rack as the holding rack is guided by the external rolling path, the service life of the bearing is prolonged, and the production efficiency is improved.

Description

A kind of vibrating screen bearing

Technical field

The utility model relates to a kind of vibrating screen bearing, relates in particular to a kind of vibrating sieve selfaligning bearing, and it belongs to field of bearings.

Background technique

Vibrating screen bearing is a kind of bearing that is used on cement and the mining machinery, and the operating mode of this kind machinery is very abominable, and impulsive load is very big, and dust is bigger, does very difficulty of seal approach.It is this that mechanically normal what use is the selfaligning roller bearing of rolling element guiding; Because impact and dust are big; The retainer of normal selfaligning roller bearing and roller hold can't stand the too big impact and the obstruction of dust, often makes the bearing inner heat and locking causes bearing to damage in advance.

Summary of the invention

In view of the defective that prior art exists, the purpose of the utility model is that a kind of vibrating screen bearing will be provided, and it adopts outer raceway and roller dual boot retainer, has reached the working life of improving bearing, the purpose of enhancing productivity.

Be the realization above-mentioned purpose, a kind of vibrating screen bearing of the technical solution that the utility model adopted, it is by outer ring, inner ring, retainer and roller; Be respectively equipped with raceway on outer ring and the inner ring, roller is loaded on the retainer, and retainer is between inner ring and outer ring; It is characterized in that: boss of retainer external diameter band, retainer contacts with outer ring raceway.

The utility model compared with prior art; Have following outstanding advantage and good effect: adopt outer raceway and roller dual boot retainer, the guiding of outer raceway has significantly reduced under impulsive load retainer and rolling element stuck and make the damage of bearing locking sintering; Retainer raceway guiding outside down; Rolling element and retainer can be not stuck because of the entering part dust, in the working life of having improved bearing, improved manufacturing efficiency.
