Abstract
Description
technical field
[0001] The invention relates to a power transmission device of an oil extraction machine, in particular to a driving wheel of a steel cable hoisting belt of an oil extraction machine. Background technique
[0002] The traditional digital automatic oil extraction machine is directly connected with the motor, the reducer, and the driving wheel shaft, and the sucker rod is driven by the steel cable lifting belt for oil extraction. One end of the steel cable lifting belt is fixed on the driving drum, and the other end is connected to the oil production rod. The steel cable lifting belt is wound repeatedly on the driving wheel (about 6,000 times per day). The machine brings the following adverse effects: 1. The steel cable belt wears too fast, resulting in frequent replacement of the steel cable lifting belt on site, excessive loss and excessive labor intensity; 2. The torque cycle of the driving wheel changes, and the motor current increases and changes according...
