Sprocket couplingThe sprocket coupling uses a common chain to engage two parallel sprocket with the same number of teeth at the same time...The quincunx-shaped elastic coupling is composed of two half-couplings with the same shape of the claws and elastic elements. The quincunx-shaped elastic element is placed between the two halves of the coupling claws to realize the coupling of the two halves. Connection and transmission.Plum-shaped elastic coupling, as the name implies, is named for its elastic plum shape. According to different elastomer materials, it can be divided into: cast nylon plum-shaped coupling, rubber-shaped plum-shaped coupling, polyurethane plum-shaped coupling; The commonly adopted elastomer is polyurethane.According to its performance and use, it can be divided into: plum-shaped elastic coupling, plum-shaped coupling for servo motor, clamping type plum-shaped coupling, etc.There are many types to choose from, such as keyway type, clamping type, extended type, flange type, etc. The quincunx-shaped coupling is to install a whole quincunx-shaped elastic ring on the jaws of two half-couplings of the same shape. In order to realize the connection of the two halves of the coupling.The power is transmitted through the squeezing between the claw and the elastic ring, and the relative deviation of the two shafts is compensated by the elastic deformation of the elastic ring to realize vibration damping.This kind of elastic coupling has been standardized, GB/T5272-2002 has five structural forms: LM type (basic type), LMD type (single flange type), LMS type (double flange type), LMZ-I type (Split brake wheel type) and LNZ-II (Full brake wheel type).There are 14 specifications for each type. The applicable shaft hole diameter d=12-160mm, the shaft hole length L=35-135mm, the nominal torque T=25-25000N.m, and the allowable speed [n]=1500- 15300r.min.
Structural characteristics of plum-shaped elastic coupling:
1. Stable work, with good vibration damping, buffering and electrical insulation properties.
2. Simple structure, small radial size, light weight, small moment of inertia, suitable for medium and high speed occasions.
3. It has large axial, radial and angular compensation capabilities.
4. Polyurethane elastic elements are resistant to oil, have large carrying capacity, and have long service life.
5. The coupling does not need lubrication, the maintenance workload is small, and it can run continuously for a long time.
6. The fixing methods include top wire, clamping and keyway fixing.
