Jiangsu Wuxi Zejia Technology.FCL elastic sleeve pin coupling are relatively widely used and are suitable for connecting two coaxial transmission shaft systems. They have the performance of compensating for the relative offset of the two shafts, shock absorption and buffering. They feature a simple and reasonable structure, convenient maintenance, symmetrical interchangeability on both sides, and allow for a large axial movement. Elastic couplings are usually made by wire cutting metal round bars. Commonly used materials include aluminum alloy, stainless steel and engineering plastics.
Elastic couplings use parallel or helical grooving systems to accommodate various deviations and transmit torque, and usually have good performance. Most elastic couplings are made of aluminum alloy, which also increases their torque-bearing capacity and rigidity, even reaching twice that of similar aluminum alloy products. However, this increased torque and rigidity will be offset to a certain extent by the increased mass and inertia.
The fixed shaft should be locked. The traditional fixing method may cause damage to the shaft or make disassembly difficult as the front end of the screw comes into contact with the shaft center. The force required to tighten the hex socket bolt, this method of fixation and disassembly is convenient and will not cause damage to the shaft center. It is a very commonly used fixation method. The magnitude and direction of the relative displacement between the two shafts make it difficult to maintain strict alignment of the two shafts after installation and adjustment.
Couplings are usually made of metal components and do not require lubrication. Couplings containing non-metallic components such as rubber are more sensitive to temperature, corrosive media and strong light, and are prone to aging. Due to reasons such as manufacturing, installation, deformation under load and temperature changes, there exists directional displacement. When the radial displacement is large, or when the angular displacement is large or for the connection of two intersecting shafts, other couplings can be selected.
