Problems solved by technology
Ordinary high-speed light-load bearings have low load. In order to facilitate the high-speed rotation of the bearing, the tolerance between the outer ring of the bearing and the bearing seat is usually small, so slipping often occurs after a period of use, which seriously reduces the transmission performance and shortens the service life. Can not be better guaranteed, greatly reducing the reliability of the bearing work

Embodiment Construction
[0013] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.
[0014] like figure 1 The preferred embodiment of the bearing structure of the present invention shown includes a bearing outer ring 1, a ball 4 and a bearing inner ring 2, the ball 4 is installed between the bearing outer ring 1 and the bearing inner ring 2, and an oil groove is opened on the bearing outer ring 1 3. The oil grooves 3 are all set inside the bearing outer ring 1, and the top is open. There are two raceways 7 inside the bearing inner ring 2, and there are two raceways 7, and they are arranged on the bearing inner ring 2 correspondingly. There is a shaft hole 5, the shaft hole 5 is opened on the bearing inner ring 2, the shaft hole 5 is provided ...

The invention discloses a bearing structure, which comprises a bearing outer ring, balls and a bearing inner ring, the balls are installed between the bearing outer ring and the bearing inner ring, an oil groove is opened on the bearing outer ring, and the oil grooves are arranged inside the bearing outer ring, And the top is open, there are two raceways inside the inner ring of the bearing, and they are arranged on the inner ring of the bearing correspondingly, there is a shaft hole above the raceway, the shaft hole is opened on the inner ring of the bearing, and there is a shaft hole in the shaft hole The shaft, the shaft and the shaft hole are connected by pins, and also include support bars arranged on the inner ring of the bearing. There are protrusions on the support bars, the protrusions are trapezoidal, and the protrusions are connected in sequence, and two adjacent protrusions A groove with an opening facing downward is formed between them. This bearing structure can directly reduce the friction surface between the shaft and the inner wall of the shaft hole, effectively reduce the friction coefficient between the shaft and the shaft hole, reduce noise, and facilitate the installation and disassembly of the bearing. The connection is reliable and can effectively ensure the rotation performance of the bearing. Improve bearing service life.
Description
technical field [0001] The invention relates to a mechanical component, in particular to a bearing structure. Background technique [0002] The bearing is the support in the mechanical transmission mechanism. It is used to determine the relative movement position of the rotating shaft and other parts. Its quality and carrying capacity directly affect the working performance of the mechanical machine, and the operation of the bearing drives other parts to move. Ordinary high-speed light-load bearings have low load. In order to facilitate the high-speed rotation of the bearing, the tolerance between the outer ring of the bearing and the bearing seat is usually small, so slipping often occurs after a period of use, which seriously reduces the transmission performance and shortens the service life. Can not get a better guarantee, greatly reducing the reliability of the bearing work. Contents of the invention [0003] The technical problem to be solved by the present invention...
