Problems solved by technology

[0002] Deep groove ball bearings include an inner ring, an outer ring, a cage and rolling elements. The cage separates the rolling elements at equal distances and is evenly distributed on the circumference of the raceway to prevent the rolling elements from colliding and rubbing against each other during operation, and to guide and drive the rolling elements. The body rolls on the correct raceway; most of the currently used cages are of the two-half type, that is, two halves of the same ring frame that are butted together are connected by rivets. The frame body includes alternately

Abstract

The invention relates to a retainer for a deep groove ball bearing with grease holes and the deep groove ball bearing made of the retainer. The retainer comprises a retainer body I and a retainer body II which can be butted together, and the retainer body I and the retainer body II comprise ball pockets and planes which are arranged alternately, wherein the surfaces of the ball pockets of the retainer body I and/or the retainer body II are provided with the grease holes. The grease holes are at non-vertex positions of an arc section, the central line of the arc section is superposed with the axis of the retainer body I, and the radius of the arc section is the vertical distance from the central line of the grease holes to the axis of the retainer body I. The retainer and the deep groove ball bearing have the following advantages: the ball pockets are provided with the grease holes, the grease can conveniently enter the part between the ball pockets of the retainer and rolling bodies, the lubricating effect is good, the lubricating property of the bearing is effectively improved, the friction is reduced, the noise is reduced, the vibration is low, and the bearing has good and reliable running quality; therefore, the bearing is more suitable for high-speed operation, and the service life of the bearing is prolonged.
