Deep groove ball bearings with split cage

Abstract

The invention discloses a deep groove ball bearing with a split cage, comprising an outer ring, an inner ring, steel balls, an upper frame body, a bearing frame and a lower frame body, the bearing frame is provided with a pocket, and the bearing frame is provided with a connection platform, the first plug-in groove and the second plug-in groove are formed on the two side walls of the connecting platform, the bottom surface of the pocket is provided with a connecting groove, an oil storage chamber is formed on the upper frame, and a positioning flange is formed on the opening of the oil storage chamber for positioning. The flange is mated with the connection groove, and the lower frame body is provided with an arc-shaped groove corresponding to the position of the pocket groove. The lower frame body is formed with a connecting seat on the upper body. One plug-in block is mated with the first plug-in slot, and the second plug-in block is mated with the second plug-in slot. The ends of the first plug-in block and the second plug-in block are provided with positioning blocks. There are positioning holes for plugging in with the positioning block, the overall structure is convenient to install, has higher stability, and improves the use effect and production and processing efficiency of the overall structure.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a deep groove ball bearing with a split cage. Background technique [0002] A deep groove ball bearing is usually equipped with a cage, which is usually assembled between the raceways of the inner ring and the outer ring. The cage usually has a ring-shaped main structure and ball pocket holes evenly distributed along the circumference. The ball pocket hole usually adopts a concave spherical surface similar to the rolling element of the ball bearing and has a slightly larger curvature radius, and is opened on the inner diameter surface and the outer diameter surface of the cage body. However, during use, under high-speed conditions of rapid acceleration or deceleration, a high temperature rise is likely to occur, causing the cage to melt and crack, and the cage is prone to impact fracture in the pocket or other positions, and attention should be paid to maintenance To ensure the...

Problems solved by technology

However, during use, under high-speed conditions of rapid acceleration or deceleration, a high temperature rise is likely to occur, causing the cage to melt and crack, and the cage is prone to impact fracture in the pocket or other positions, and attention should be paid to maintenance The lubricating state of the cage balls should be replenished in time, but the existing cages are difficult to replenish oil, and the assembly is also very inconvenient, which reduces the overall use effect of the cage and is not conducive to improving production and processing efficiency.
