Steel Flexible Diaphragm Coupling
,Disc Flexible Diaphragm Coupling
Diaphragm Coupling Used in Textile machinery
Features of disc coupling:
- Axial compensation ability is strong, compared with the gear coupling. Angular displacement can be doubled.Flexible, allow axial, radial and angular displacement.
- It has obvious damping effect, no noise, no wear.
- Adapt to high temperature (-80+300).Can work in harsh environment.And safe operation in the impact, vibration environment.
- High transmission efficiency, up to 99.86%.Especially suitable for medium and high speed power transmission.
- Simple structure, light weight, small size, easy to assemble and disassemble.No lubrication is required.
- Accurately transfer the speed, running without slip, can be used for the transmission of precision machinery.
