Cage processing method, cage and centripetal ball bearing

Abstract

The invention relates to technical field of bearing processing, especially to a cage processing method, which includes: step A. shaping a moulding member to make the obtained moulding member to form a ball bag, wherein the center diameter of the ball bag is smaller than a standard center diameter by a preset difference; and step B. punching a hole on the moulding member to form a nail hole on the moulding member, wherein the center diameter of the nail hole is equal to the standard center diameter. After the cage processed by the method is fixed at two sides of a rolling element through rivets, a contact point of the rolling element and the cage is just positioned at center position of the ball bag of the cage, friction between the rolling element and the cage is smaller, wearing between the rolling element and the cage is less, thereby prolonging service life of a centripetal ball bearing, simultaneously, relative vibration between the rolling element and the cage is smaller, noise between the rolling element and the cage is lower, thereby improving use performance of the centripetal ball bearing. The invention also provides the cage and the centripetal ball bearing.

Description

technical field [0001] The invention relates to the technical field of bearing processing, in particular to a method for processing a cage, a cage and a radial ball bearing with the cage. Background technique [0002] Radial ball bearings are a commonly used component in modern machinery, which can withstand loads of different sizes during high-speed motion. Radial ball bearings are widely used in general industry, automobile industry, agriculture, chemical industry and home appliance industry. [0003] Radial ball bearings generally include inner rings, outer rings, rolling elements and cages. The inner ring is used to assemble with the shaft end of the rotating shaft to provide support for the rotating shaft. Usually, the outer side of the inner ring is provided with a concave deep groove structure suitable for the rolling elements. The outer ring is usually assembled on a fixed part to provide support for the inner ring. To provide a foundation, usually a concave deep g...

Problems solved by technology

[0008] However, when two cages of this structure are fixed on both sides of the rolling element by rivets, the contact point between the ball pocket and the rolling element will be misaligned with the center of the ball pocket, and the contact point between the ball pocket and the rolling element will be located at the center of the ball pocket. The position of the pocket close to the inner ring of the radial ball bearing will increase the friction between the rolling elements and the cage, and the greater friction between the rolling elements and the cage will cause both the rolling elements and the cage to Severe wear will reduce the service life of the radial ball bearing; at the same time, during the operation of the radial ball bearing, serious relative vibration will occur between the rolling element and the cage, which will generate large noise, making the surrounding The environment is polluted by noise
