Self-lubricating bearing

Abstract

The invention discloses a self-lubricating bearing, in particular a bearing which has lubricant oil inside, and the lubricant oil can produce lubrication and can be recycled for reusing. The bearing can be made of porous materials; the inside of the bearing is provided with a penetrated central shaft holes, and the outer surface of the bearing or the inner wall surface of the central shaft hole is provided with an oil storage tank for accommodating the lubricant oil; the external part of the bearing is a shell which can be coated, can use the inner hole to accommodate the bearing, and is sleeved at a shaft core of a motor by the central shaft hole of the bearing; when the shaft core of the motor rotates, the lubricant oil contained in the bearing seeps along the direction of the shaft core to form lubrication between the outer surface of the shaft core and the inner surface of the central shaft hole of the bearing, and the lubricant oil seeps out to the part between the outer surface of the bearing and the inner hole wall surface of the shell to concentrate in the oil storage tank, thereby the functions of providing oil, returning oil, protecting oil, storing oil and the like are achieved, and the service life of the self-lubricating bearing is further prolonged.

Description

technical field [0001] The invention relates to a bearing. Background technique [0002] In the position where many mechanisms need to rotate and rotate, bearings are usually installed to assist the mechanism to rotate more smoothly. At the same time, it can limit the mechanism and play a supporting role. However, the bearing will generate friction and heat during long-term operation. Phenomenon, it is necessary to add lubricating oil or lubricating liquid to assist lubrication, so that the bearing can rotate smoothly and avoid heating of the bearing. Therefore, if the bearing can rotate normally, there must be a lubricating medium. Lubricating media such as: water, air or lubricating oil, and during the use of the bearing, it is necessary to add lubricating oil frequently, which is not only troublesome but also inconvenient for the staff.

[0002] In the position where many mechanisms need to rotate and rotate, bearings are usually installed to assist the mechanism to rotate more smoothly. At the same time, it can limit the mechanism and play a supporting role. However, the bearing will generate friction and heat during long-term operation. Phenomenon, it is necessary to add lubricating oil or lubricating liquid to assist lubrication, so that the bearing can rotate smoothly and avoid heating of the bearing. Therefore, if the bearing can rotate normally, there must be a lubricating medium. Lubricating media such as: water, air or lubricating oil, and during the use of the bearing, it is necessary to add lubricating oil frequently, which is not only troublesome but also inconvenient for the staff. If you forget to replenish the lubricating oil in a timely manner, the bearing will run Rotating in the state of lubrication will cause the bearing to generate friction and heat, and affect the normal rotation of the bearing; then some operators add lubricating oil to the sintered self-lubricating bearing, because the shell of the self-lubricating bearing has Fine holes, so that the lubricating fluid can be impregnated in the bearing, that is, no additional lubricating oil is required

[0003] Generally, when the self-lubricating bearing is in use, during the operation of the self-lubricating bearing, the lubricating oil will seep into the inner diameter surface of the bearing to lubricate the interface between the shaft core and the bearing, and when the bearing is not running, the lubricating oil will be sucked into the self-lubricating bearing again In the hole of the bearing to achieve the purpose of recycling; but during the operation and rotation of the bearing, not all the lubricating oil that seeps out will be re-absorbed back into the housing hole of the self-lubricating bearing, because the lubricating oil will have Factors such as evaporation, throwing out, overflow, or combination of particles generated by friction with the shaft core will cause loss and disappearance, and will also reduce the oil content of the self-lubricating bearing, resulting in the frequency and time of self-lubrication of the self-lubricating bearing during operation. will be reduced, shorten the service life of self-lubricating bearings
