AI Technical Summary
Existing drive belts are prone to derailment during power transmission, causing damage and loss to the equipment.
A belt straightening device for a pumping unit was designed, comprising a ladder base, a lower rail plate, an upper rail plate, and a straightening assembly. The belt is limited and adjusted by the clamps, winding rods, rollers, and other structures in the straightening assembly to maintain the stability of the belt during transmission.
It improves the safety and reliability of drive belts, reduces safety risks and maintenance costs, reduces unplanned downtime and material replacement frequency, and optimizes the stability and efficiency of power transmission.
