First, the application of matters:
Rolling bearings make fine parts; therefore, the demand is correspondingly stable when used; the use of high-performance bearings; if not used properly; can not reach the expected function; therefore; the use of bearings should focus on the following:
1. Adhere to the hygiene of the bearing and its surrounding environment. Even the light laughter that is invisible to the naked eye enters the bearing; it will also add bearing wear; oscillation and noise.
2, the use of the device should be careful and careful; does not allow strong stamping; does not allow the hammer to directly hit the bearing; does not allow the pressure to pass through the rolling body.
3, the use of appropriate and precise means of things; try to use special things; try to avoid the use of cloth and short fibers and the like.
4, to avoid the corrosion of the bearing; directly take the bearing by hand; to wash away the sweat on the hand; and apply high-quality mineral oil before operation; especially in the dry season and summer to pay attention to rust.
Second, the cooperation of bearings:
1. Selection of cooperation:
The inner diameter and outer diameter dimensions of the rolling bearing are made according to the standard; the bearing inner ring and the shaft; the cooperation between the outer ring and the seat hole can only be achieved by the public service of the steering journal and the seat hole. The cooperation between the inner ring of the bearing and the shaft is made by the base hole; the cooperation between the outer ring of the bearing and the seat hole is made by the shaft. Correct selection and cooperation; it is necessary to know the practical load conditions of the bearing; the working temperature and other requirements; and it is very difficult in practice. Therefore, most of the conditions are based on the use of fine research to select cooperation.
2. The excessive win between the load ferrule and the shaft or the outer casing depends on the load. Now the mother-in-law, the brakes, the media, the tomb, the tomb, the mother, the sorcerer, the media, the tomb.
