Coated bearing is a new type of bearing made of steel and polymer materials, which can not only improve impact resistance, but also extend service life. The components of this bearing include an inner and outer ring, as well as a rubber coating made of polymer material. The main function of the rubber coating layer is to effectively absorb and disperse the impact force when the bearing is running, so as to improve the impact resistance of the bearing.
The impact resistance of rubberized bearings is mainly reflected in the following aspects:
1. Elasticity and toughness of polymer materials: The coated layer is usually made of polymer materials, such as polyurethane, polytetrafluoroethylene,rubber etc. These materials have good elasticity and toughness, and are able to absorb and disperse impact forces while the bearing is in operation. For example, in a bicycle time trial, the sealing ring on the bearing is often removed to reduce friction and increase speed, but doing so reduces the durability of the bearing. In this process, due to the presence of the rubber covering, the bearing can withstand a certain impact force, thus prolonging the service life.
2. Thickness and quality of the covering: The thickness and quality of the coverings have a great impact on the impact resistance of the bearing. In general, the thicker the coated layer, the better the quality, and the stronger the impact resistance of the bearing.
3. Structural design of the bearing: The structural design of the bearing will also affect the impact resistance of the bearing. For example, a spherical design of a rubber bearing is more impact resistant than a roller design of a rubber roller bearing. In addition, the size and shape of the bearing also have an impact.
4. Lubrication conditions: The lubrication conditions of the bearing will also affect the impact resistance of the bearing. For example, in adverse weather conditions, there is no lubricant that can last a lifetime without having to be replaced. If the lubrication conditions of the bearing are not good, the rubber coating is easy to wear, which reduces the impact resistance of the bearing.
To sum up, the impact resistance of rubber bearings is mainly determined by the elasticity and toughness of polymer materials, the thickness and quality of the rubber covering, the structural design of the bearing, and the lubrication conditions. In practical application, we need to select the appropriate rubber bearing according to the specific use environment and requirements, and pay attention to the maintenance and maintenance of the bearing to ensure its impact resistance and service life.
As usual, people always choose rubber bearing, polyurethane roller bearings etc for robot industry, machinery industry etc
