The working principle of PK multi-wedge belt wheel is a transmission process which is composed of a plurality of inclined surfaces and forms a number of hydrodynamic pressure wedges along its circumference when working. PK multi-wedge belt, also known as PK multi-slot belt, is mainly used in engine, motor and other power equipment transmission.
PK multi-wedge pulley is matched with PK multi-wedge belt, Qilong 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, PK 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 PK multi-wedge pulley drawings according to the internal hole, specifications, width, keyway and other parameters for you to draw the corresponding PK multi-wedge pulley drawings for precise and accurate manufacturing. As long as you need, we can produce the PK multi-wedge pulley you need for you.
The equipment we use to process PK 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.
