The working principle of PM multi-wedge belt wheel is a transmission process consisting of a plurality of inclined surfaces and forming a number of fluid dynamic pressure wedges along its circumference when working. PM multi-wedge belt, also known as PM multi-slot belt, is mainly used in engine, motor and other power equipment transmission.
PM multi-wedge pulley is matched with PM multi-wedge belt, Qirong PH multi-wedge pulley material to 45# steel, hard aluminum alloy is the most common, other can also choose cast iron, copper, nylon and other suitable materials for processing, the specific selection is based on customer needs, PM multi-wedge pulley surface treatment has natural oxidation, black, galvanized, plated zinc, high frequency hardening and other treatment.
We can also provide you with multi-wedge belt and multi-wedge pulley drawings production and processing, we can also provide you with PM multi-wedge pulley drawings according to the internal hole, specifications, width, keyway and other parameters for you to draw the corresponding PM multi-wedge pulley drawings for precise and accurate manufacturing. As long as you need, we can produce the PM multi-wedge pulley you need for you.
The equipment we use to process PM multi-wedge pulley for you is fully CNC! Product quality is fully guaranteed! Will be able to make you really satisfied!
Our purpose: to return customers with the best quality, to support customers at the lowest price, to cooperate with customers at the fastest speed.
We rely on quality, credit, price, speed, has become one of the main suppliers of China’s transmission industry.
