Beschreibung
Zusammenfassung:	A double-speed regulating anti-slip slide fitted belt pulley for the electric motor of an oil pumping machine is provided, which mainly solves the problem that the existing slide fitted belt pulleys may be out of synchronization with the electric motor due to frequent replacement and sliding in rainy days. The belt pulley is characterized in: two groups of annular V-belt slots (2) in different nominal diameters are arranged in circumferential direction on the outer wall of the belt pulley body (1); a plurality of arc shape anti-slip grooves (5) are arranged on the sides of each V-belt slot (2), and the anti-slip grooves (5) on adjacent V-belt slots (2) are staggered to each other. The utility model has advantages such as reduced replacement frequency and anti-slip in rainy days, and can improve the working efficiency of the service men and the oil pumping efficiency of the oil pumping machine.
