Embodiment Construction

[0021] In order to make the structure and function of the present invention clearer, the technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0022] see attached Figure 1-5 , a plastic cage for double-row deep groove ball bearings, including a cage body 1, the cage body 1 is provided with a pocket 7 for placing steel balls, the pocket 7 is open to one side, and two adjacent pockets are There is a connecting section 8 between 7, and a weight-reducing groove 9 with a semicircular structure is provided on the side of the connecting section 8 away from the opening of the pocket. Considering the requirements of weight reduction and structural strength, the diameter of the weight reduction groove is about 0.85~0.92 times the diameter of the steel ball to ensure that the overall center of gravity of the cage is infinitely close to the c...

Abstract

The invention belongs to the technical field of bearing equipment manufacturing, and particularly relates to a plastic retainer for a double-row deep groove ball bearing and a bearing thereof, the plastic retainer comprises a retainer body, the retainer body is provided with pockets for placing steel balls, the pockets are opened towards one side, a connecting section is arranged between every two adjacent pockets, and the connecting section is connected with the retainer body. A weight reduction groove is formed in the side, away from an opening of the pocket, of the connecting section, and the two ends of the weight reduction groove are in fillet transition with the end face of the retainer body. According to the retainer, the overall rotation performance of the bearing can be improved under the condition that the center of the bearing is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of bearing equipment manufacturing, and in particular relates to a plastic cage for a double row deep groove ball bearing and a bearing thereof. Background technique [0002] Double row deep groove ball bearings are mainly used in applications such as pumps and some air compressors. Its radial load capacity can reach about 1.62 times that of single row deep groove ball bearings, but the internal space is more compact. However, due to the limitation of its structure and space, an integral solid cage or a stamped cage cannot be used, and a plastic cage inserted from the end face is usually used. There is a certain amount of lock between the opening of the cage pocket and the steel ball, which can ensure that the cage will not fall off after being installed. For a long time, the details of the design of the double row deep groove ball cage have not been considered enough, especially the influence of the cente...
