Introduction
A rubber centering ring is a common sealing element, usually made of rubber material, and has an annular cross-section.
In the operation of machinery and equipment, the connection and rotation of the centering ring between the shaft and sleeve, shaft and bearing seat, housing, and end cover are crucial.
Advantages
1. Good elasticity: The rubber centering ring has excellent elasticity and can adapt to the vibration and deformation of the shaft or shell.
2. Good wear resistance: The surface of the centering ring is covered with a layer of special wear-resistant material, which can maintain its shape and function for a long time.
3. Strong anti-aging performance: The centering ring is made of high-quality rubber material and treated with special processes to maintain stable performance during long-term use.
4. Torque transmission: The centering ring can effectively transmit torque and ensure the concentricity of the two shafts or shells.
5. Absorb vibration and impact: The rubber centering ring has good shock absorption performance, can absorb vibration and impact, and reduces the wear and deformation of the equipment.
Classification
To begin assembling the O-ring, use the following instructions as a guide:
1. Classification according to material: Rubber centering rings can be divided into NR centering rings, SBR centering rings, Silicone centering rings, etc. according to the rubber material used.
2. Classification according to structure: it can be divided into single-layer centering rings and multi-layer centering rings. Single-layer centering rings are made of one layer of rubber material, while multi-layer centering rings are composed of two or more layers of rubber material to provide better elasticity and wear resistance.
3. Classification according to function: it can be divided into ordinary centering rings and sealed centering rings. Ordinary centering rings are mainly used to connect two shafts or housings and maintain their concentricity. The sealing centering ring adds a sealing function to the ordinary centering ring and can provide better sealing performance.
4. Classification according to shape: centering rings can be divided into circular centering rings, square centering rings, and centering rings of other shapes. Circular centering rings have better elasticity and wear resistance, while square centering rings provide better support and stability. Centering rings of other shapes can be customized according to specific application scenarios.
