The elastic sleeve 20MG40.11.02 of the coal mill is an important connecting element, and its main functions include: 1. Transmit torque: The elastic sleeve plays the role of transmitting torque in the coupling of the coal mill. It connects two shafts or shafts and rotating parts, and rotates together during the transmission of motion and power. 2. Compensate for axial displacement: The elastic sleeve can compensate for axial displacement and allow a certain amount of axial expansion and contraction, thereby adapting to the thermal expansion or contraction of the shaft and reducing the wear of the equipment. 3. Absorb vibration and impact: The elastic sleeve can absorb vibration and impact from the operation of the coal mill and reduce damage to the shaft and bearings. 4. Reduce noise: The use of elastic sleeves helps to reduce noise during the operation of the coal mill and improve the comfort of the working environment. 5. Easy to install and maintain: Due to the structural characteristics of the elastic sleeve, it is easy to install and maintain, which helps to shorten the downtime of the coal mill. 6. Improve safety: As a safety device, the elastic sleeve is sometimes used to prevent the connected parts from being subjected to excessive loads, thereby protecting the key components of the coal mill. |
