AQM,AQMZ series steel ball energy-saving and safety couplingDetailed product description：

Characteristics of AQM steel ball energy-saving and safety coupling

(1) Good starting performance, can transform the loaded starting of the motor into no-load starting, and achieve soft starting of the working machine; Reduce starting current and minimize starting energy consumption.
(2) Saving energy and equipment investment costs can solve the unreasonable phenomenon of "big horse pulling small car" when starting machines with loads, improve the power factor of the power grid, reduce reactive power losses, save energy, simplify motor starting equipment, and reduce equipment investment costs.
The transmitted torque can be adjusted, making it easy to achieve overload safety protection. When the working machine is overloaded or stuck, the steel ball diaphragm safety energy-saving coupling automatically slips, which can prevent the motor from burning out and other components from being damaged.
(3) Except for the starting and braking stages, the steel ball diaphragm type safety energy-saving coupling has no speed difference between the driving shaft and the driven shaft, no friction loss, and high transmission efficiency.
(4) The steel ball diaphragm type safety and energy-saving coupling adopts stainless steel metal elastic elements, which can compensate for the offset of the two shafts connected within a certain range and have a certain degree of vibration reduction and buffering effect. And metal elastic components can adapt to high temperature usage environments, with more reliable transmission and less maintenance workload.
