Technical Field

[0001] The utility model relates to the field of mechanical parts, in particular to a clamping bearing. Background Art

[0002] Bearings are a common mechanical part, usually used to support mechanical rotating bodies. By designing balls between the inner and outer bearings, the friction between the inner and outer bearings is reduced.

[0003] Common bearings are usually provided with an inner bearing and an outer bearing, and the inner bearing is usually provided with a ball ring body. Balls are connected to the inner wall of the ball ring body through sliding, which reduces the friction between the inner bearing and the outer bearing, reduces the wear between the parts of the mechanical equipment during operation, and thus improves the service life of the mechanical equipment.

[0004] Considering that the balls in the inner wall of the bearing are the most severely worn during the use of the bearing, usually when the balls are replaced, the entire ring body is replaced together, which means that some balls need to be replaced even when the wear is not serious. Considering that manufacturers or large mechanical equipment need to replace a large number of balls during maintenance, the entire ball ring body needs to be replaced, which increases the cost of replacement and maintenance. Therefore, a snap-on bearing is proposed to solve the above problem. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a snap-on bearing, which aims to improve the existing technology in which the bearing balls are replaced by replacing the entire ring body, resulting in the replacement of some balls that are not seriously worn. If a large number of balls need to be replaced during manufacturer or large-scale equipment maintenance, the cost of replacing the entire ring body is high.

[0033] Reference Figure 3 - Figure 4 The inner bearing assembly 2 includes an inner bearing housing A202, the front end of the inner bearing housing A202 is fixedly connected to a limit plate 203, the design of the limit plate 203 makes the inner bearing housing A202 drive the limit plate 203 to rotate at the same time during its rotation, so that the limit plate 203 drives the ball mechanism 3 to rotate at the same time, the front end of the inner bearing housing A202 is fixedly connected to a column 204, the inner wall of the column 204 is slidably connected to a wedge block 206, which keeps the wedge block 206 moving laterally along the inner wall of the column 204, the outer wall of the wedge block 206 is fixedly connected to one end of a spring A207, and the other end of the spring A207 is fixedly connected to the column 2 04 is fixedly connected, and the force of spring A207 drives the wedge block 206 to move outward, so that the wedge block 206 maintains a clamping and fixing effect with the limiting groove 205. The inner bearing shell B201 is inserted into the outer wall of the column 204, and the inner bearing shell A202 is connected and fixed to the inner bearing shell B201 by plugging and clamping to maintain the stability of the ball mechanism 3 set on its inner wall. A limiting groove 205 is provided on the inner bearing shell B201, and the inner wall of the limiting groove 205 is clamped with the outer wall of the wedge block 206, which plays a fixing effect after the inner bearing shell A202 is connected to the inner bearing shell B201.

[0034] Reference Figure 3 - Figure 4A push rod 209 is slidably connected to the inner bearing housing B201, and the length of the push rod 209 is smaller than the position of the ball 304, so that the outer wall of the push rod 209 does not contact the inner wall of the outer bearing assembly 1. The outer wall of the push rod 209 is fixedly connected to one end of the spring B208, and the other end of the spring B208 is fixedly connected to the inner wall of the inner bearing housing B201. The push rod 209 is driven inward by the force of the spring B208, and one end of the push rod 209 contacts the outer wall of the wedge block 206. Through the design of the push rod 209, the staff can press and control the wedge block 206 on the outer wall of the inner bearing assembly 2.

[0035] Reference Figure 3 - Figure 5 A ball mechanism 3 is provided between the inner bearing housing A202 and the inner bearing housing B201. The ball mechanism 3 includes an annular connector 301. One side of the annular connector 301 is fixedly connected to an arc-shaped insert plate 305. The other side of the annular connector 301 is fixedly connected to an arc-shaped concave frame 303.

The inner wall of the sliding groove is slidably connected to the outer wall of the ball 304 to maintain the stability of the ball 304 during movement.

[0036] Working principle: When the ball bearings installed in the inner wall of the bearing need to be replaced, the nut needs to be rotated first to separate the nut from the bolt, thereby disassembling the outer bearing housing A101 and the outer bearing housing B104, and taking out the inner bearing assembly 2 installed inside.

[0037] At the same time, the inner bearing housing A202 is connected and fixed to the inner bearing housing B201 by means of a snap connection. In the case of releasing the fixation, the staff needs to press the push rod 209 provided on the inner bearing housing B201 inward so that the push rod 209 squeezes the outer wall of the wedge block 206, causing the wedge block 206 to shrink into the inner wall of the column 204, thereby releasing the snap connection between the inner bearing housing A202 and the inner bearing housing B201, disassembling them, and taking out the ball mechanism 3 placed on the inner wall.
