Description

TECHNICAL FIELD

[0001] The utility model relates to bearing technical field, specifically, relate to a deep groove ball bearing with dustproof function. BACKGROUND

[0002] Deep groove ball bearing, also known as single row radial ball bearing, is the most widely used in rolling bearings. The traditional deep groove ball bearing structure includes outer ring, inner ring, a group of steel balls and a retainer, but the steel ball part of this structure is exposed to the outside, directly contacting with air. When the bearing is running in a harsh environment, foreign matter such as sand, dust and iron filings from the outside is easy to enter the bearing interior, contacting with the steel ball, causing the steel ball surface to wear or even damage, ultimately affecting the performance and service life of the bearing.

[0003] At present, the common deep groove ball bearing increases the dust plate between the inner and outer rings for blocking foreign matter from entering. However, the connection structure of the dust plate and the inner and outer rings of the existing design still has the defect of not being tight enough, so that dust and other small particles can still penetrate into the bearing interior, causing wear to the steel ball. This not only shortens the service life of the steel ball, but also adversely affects the performance and service life of the entire deep groove ball bearing.
