The effect of the bearing bracket and the classification of the bracket are one of the primary parts of the bearing; there are four fundamental effects of the bracket in the rolling bearing: /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
1. Don't leave the roll,
2. Hold the roll itself or stick it to a ferrule,
3. Guide the roll to roll on the correct track,
4. Orientation of the roll body, reduce conflicting power.
According to the production process and the data used, the frame can be divided into: low- and medium-carbon steel as the raw material for the stamping frame, high-strength copper alloy (lead brass, nickel, silicon bronze, etc.), zinc-aluminum alloy, and spheroidal ink. The alloy body of cast iron and other raw materials is adhered to the frame, the engineering plastics with polyamide resin as the raw material adhere to the frame, and the phenolic bakelite solid body with the phenolic laminated cloth tube as the raw material adheres to the frame. The stamping and holding frame is high in production efficiency; the raw material is light; Good strength; cover a wide range and widely used.
The fundamental requirement of insisting on the depiction of the frame is to satisfy the requirements of the maximum bearing load and the rotation accuracy and speed of the bearing in the necessary space and layout strength; the requirements of the bearing in the main machine and the requirements of guiding the gap can be determined; Or the rolling method of the rolling body; and then determine the layout and main parameters. The rolling bearing is in operation; the bearing heat and wear are formed due to the sliding conflict; especially under the condition of high speed working; because of the effect of centrifugal force and inertial force; Collision, conflict wear and heat of internal rolling body, inner and outer ring and the support frame; burns and cracks will be formed when the frame is severe; the bearing can not be used normally; the damage of the frame is a large part of the bearing failure method; The reason for the damage of the frame is one of the primary reasons for the maintenance of the raw materials. Therefore, the raw materials of the bearing support frame should have outstanding mechanical strength, dimensional stability, outstanding plasticity and workability.
Because it insists on the unique processing method or the difficulty of the process; and considers the influence of various factors such as force, smoothness, speed and temperature, as well as the demand for high speed, high precision, heavy load, long life and low noise of the bearing; The continuous improvement and development of bearing support skills has become a must.
