GM Series Winding Flexible Coupling for Step Moter
Structure of Winding Flexible Coupling :
Elastomeric Winding Couplings contain an elastomeric compound
pre-compressed with rubber to provide additional strength and
extended service life. This coupling can accommodate all types of
misalignment. The wheel hub is made of high-strength aluminum
alloy, which is light and corrosion-resistant. The rubber component
is mainly used for shock absorption, smooth and quiet power
transmission, thereby protecting the driving force and driving the
machine.
Easy installation, since the rubber part is a split insert, it can
be plug-in installation after shaft alignment.
Elastomeric couplings use parallel or helical groove systems to
accommodate various deviations and transmit torque precisely.
Winding couplings usually have good performance and price
advantages. In many practical applications of stepping and servo
systems, elastic couplings are the first choice. The one-piece
design allows the elastic coupling to transmit torque with zero
backlash and maintenance-free advantages. There are two basic
series of elastic couplings: helical groove type and parallel
groove type
