ever-power transmission 1

LAK saddle block elastic coupling belongs to tire type coupling. LAK saddle-shaped elastic coupling is a mechanical part used to connect two shafts (active shaft and driven shaft) in different mechanisms so that they can rotate together to transmit torque.

LAK saddle block elastic coupling is used to connect two coaxial transmission shafts.It has radial, axial and angular compensation and shock absorption performance.The ambient temperature is -20~+80℃, and the nominal torque transmitted is 63~50000N·m.In high-speed and heavy-load power transmission, some couplings also have the function of buffering, damping and improving the dynamic performance of the shafting. LAK

The LAK saddle-shaped elastic coupling is composed of several saddle-shaped rubber blocks connected with the main and driven end half couplings through bolts to transmit torque. The structure is simple, the number of parts is small, the assembly and disassembly are convenient, and the maintenance is easy. The vibration damping and large axis offset compensation performance, the heat generated by movement and deformation can be automatically dissipated by rotation. The full range of saddle-shaped elastic elements has only four specifications, and the universal interchangeability is good, which is beneficial to reduce costs.It can be used in mining, metallurgy, shipbuilding, textile and other industries.
