Winding Flexible Dc Motor Shaft Coupler Spline GM Series
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
