Abstract
The invention relates to a deep groove ball bearing with a pulley groove on the outer diameter of an outer ring of the deep groove ball bearing, which comprises the outer ring, an inner ring, a retainer cover, a retainer seat, a steel ball and rivets. The outer diameter of the outer ring is provided with the crescent pulley groove which only needs finish turning instead of grinding, so that cost is reduced, friction force is increased when the deep groove ball bearing is used, and the problem of relative sliding of the bearing is solved. The invention particularly relates to a pulley bearing, which is suitable for pulleys and has the advantages of convenience in mounting and flexibility in use.
Description
Technical field
The present invention relates to a kind of bearing.
Background technique
Be applied to construction industry at present, family's compact applications accessory all can use simple and easy sheave block, but these pulleys pulley bearings of special use useless is all given to use and brought inconvenience.
Summary of the invention
To above-mentioned deficiency, the present invention proposes the deep groove ball bearing that has pulley groove on the external diameter of a kind of outer ring, solved problem easy to use, also give to use to have solved safety problem.
The present invention has constructed the deep groove ball bearing that has pulley groove on the external diameter of a kind of outer ring, by outer ring, inner ring, retainer lid, the bearing that keeps stand, steel ball and rivet to constitute.The middle part of outer ring outer cylinder is provided with the pulley ditch of a crescent moon slot type.
Advantage of the present invention is: reduce cost of labor, reduced labor intensity, ensured personal security, solved commonly used and simple question, design the pulley bearings that a suitable pulley uses, have easy for installationly, use flexible characteristic.
Description of drawings
The assembly structure schematic representation of Fig. 1 pulley bearings of the present invention;
The outer ring schematic representation of Fig. 2 pulley bearings of the present invention.
Embodiment
The deep groove ball bearing that has pulley groove on the external diameter of outer ring as shown in Figure 1 comprises outer ring 01, inner ring 02, first retainer 16 and second retainer 56, steel ball 04, rivet 09; Outer ring 01 external diameter is provided with the pulley ditch of a crescent moon slot type, and this pulley ditch only needs finish turning to get final product, and does not need grinding, has reduced cost, and strengthens frictional force when using, and has solved the slide relative problem.
