1. The application of the rolling bearing is a fine part; therefore, the demand is correspondingly stable when using it; it has changed the use of high-performance bearings; if it is not used properly, it can not reach the expected functional effect; therefore, the use of bearings should focus on the following matters : /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
.1) Adhere to the hygiene of the bearing and its surroundings. Even if the light dust that is invisible to the naked eye enters the bearing; it will also add bearing wear; oscillation and noise.
.2) Careful and careful when using the device; do not allow strong punching; do not directly hit the bearing with a hammer; do not allow pressure to pass through the rolling body.
.3) Use appropriate and precise means of installation; use special things as much as possible; try to avoid using cloth and short fibers.
.4) Avoid the corrosion of the bearing; when taking the bearing directly by hand; wash the sweat on the hand thoroughly; and apply it with high-quality mineral oil; then pay special attention to rust prevention during the dry season and summer.
2. Cooperation. 1) Collaborative selection of the inner diameter and outer diameter dimensions of the rolling bearing is 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 through the operation of the journal and the seat. The public service of the hole is completed. 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; working temperature and other requirements And in practice it is very difficult. Therefore, most of the situation is based on the use of fine research to select cooperation.
.2) Load property selection cooperation should first consider the rotation of the load vector relative to the ferrule. According to the composition, the radial load vector is related to the rotation condition of the ferrule; the composites accepted by the ferrule can be divided into: fixed load, rotary load and sway load.
a. The fixed load acts on the radial load of the ferrule; it is accepted by a part of the ferrule raceway; and is transmitted to the corresponding part of the shaft or the bearing housing; this load is called the fixed load. It is characterized by the radial composition. The load vector is relatively stopped with the ferrule. The ferrule that accepts the directional load can be loosely cooperating.
b. The rotating load effect is on the ferrule. The radial load rotates in the circumferential direction of the raceway; it is accepted by each part in turn; this load is called the rotating load; it is characterized by the composition of the radial load vector related to the ferrule rotation. Accepting the rotation The ferrule of the load should be selected tightly; in special circumstances; if the load is very light; or the ferrule only happens to change at a low speed under heavy load; when the bearing is hard and the surface is rough, the ferrule receives the rotating load. Can also choose a looser cooperation.
c. The swaying load effect on the ferrule constitutes the radial load direction; this load condition is called the sway load or the non-directional load; it is characterized by the composition radial load vector on the effect ferrule in the certain area of ​​the ferrule raceway Swing; acceptable for the required area of ​​the raceway; or the load on the bearing is the impact load; the oscillating load; its direction; the load whose value is often changed. The cooperation of the bearing inside the bearing, the outer ring and the shaft, and the bearing housing hole Should choose to work closely.
.3) The excessive win between the load ferrule and the shaft or the outer casing depends on the large load. Now the mother Han æŽ æŽ æŽ èŸ® 蟮 蟮 浚 浚 浚 汉 汉 汉 . . . . . . . . . . . . . . . The load p is divided into three conditions: “lightâ€, “normal†and “heavy†load.
.4) Roughness of the cooperation appearance and the roughness and shape of the public service cooperation; directly affect the function of the product; such as wear resistance; corrosion resistance and cooperative nature. For this reason; And the shape of the shell hole and the roughness requirements of the cooperation appearance; regarding the nature of stability and cooperation; it is essential to improve the joint strength of win-win cooperation.
