1. Product introduction and applicable
scope Serpentine spring coupling is an embodiment of
high-torque of gear coupling and flexibility of flexible coupling,
for applications where high torque is required, it is the simplest
and most economical
coupling. 2. Structural
features T*0 basic type coupling: use for double flexible
closed design of four-bearing system. It is characterized by
combination of horizontally half split housing, serpentine spring
and coupling, which allows replacement easily-worn parts without
moving the equipment
connected. T*0 high-speed coupling: double flexible closed
design. It is characterized by combination of vertically split
steel housing and serpentine spring as well as coupling, mainly
used for the operating conditions of high speed
rotation. T*1 Double-flange type coupling, T*5 single-flange
type coupling: the middle section can be disengaged in order to
facilitate maintenance of bearings and seals of the connected
equipment. They are very ideal for use in
pump. T*3 brake disc type coupling: it is better than
the drum type brake in terms of cost, structure and performance
etc. 3.Type codes of coupling shaft hole and
