Embodiment Construction
[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.
[0028] see Figure 1-7 , an embodiment provided by the present invention: a new type of bearing seal cover and bearing sealing structure, including a bearing outer ring 1 and a bearing inner ring 2, the bearing inner ring 2 is arranged inside the bearing outer ring 1, and the bearing inner ring 2 There is an installation hole 3 at the middle position of the shaft. The installation hole 3 is used to connect with the shaft body that needs transmission. When the shaft body rotates and drives, it is guided by the inner ring to rotate synchronously, so as to ensure the rotation accuracy of the shaft body. The inner ring of the bearing 2 and the bearing outer ring 1 are in...

The invention discloses a novel bearing sealing cover and a bearing sealing structure, relates to the technical field of bearings, and aims to solve the problems that a clamping jaw structure adopted by an existing bearing sealing cover is easy to break and not long in service life after being assembled and disassembled for multiple times, and the sealing structure adopted by the sealing cover is relatively simple and not obvious in actual effect. A bearing inner ring is arranged in a bearing outer ring, a mounting hole position is formed in the middle of the bearing inner ring, nine balls are mounted between the bearing inner ring and the bearing outer ring, and ball grooves are formed in the connecting positions of the balls and the bearing inner ring and the bearing outer ring. The ball grooves, the bearing inner ring and the bearing outer ring are integrally formed, ball retainers are installed on the outer walls of the balls, the balls are in rolling connection with the ball retainers, and sealing grooves are formed in the two sides of each ball retainer.
Description
technical field [0001] The invention relates to the technical field of bearings, in particular to a novel bearing sealing cover and a bearing sealing structure. Background technique [0002] Bearing is an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. In order to ensure its long-term effect, it needs to be installed on its side Sealing cover to ensure dustproof performance, such as application number 202010931239.6 named a bearing sealing cover, the structure includes a sealing cover main body, fixed claws are arranged on both sides of the sealing cover main body, the outer surface of the sealing cover main body An outer ring rubber strip is provided, an inner ring rubber strip is provided on the inner side of the outer ring rubber strip, a side sealing strip is provided on the inner and outer surface of the main body of t...
