Abstract
The invention relates to a double speed ratio gear reducer for a workover rig winch. Two sets of gear pairs with different speed ratios are meshed to an input shaft and a regulating shaft, two gears on the input shaft are connected with a speed control gear to conduct outputing according to the corresponding speed ratio through an inner sleeve, and therefore input with different speed ratios and corresponding output are achieved. A middle shaft is sleeved with a shaft sleeve, the shaft sleeve idles on the middle shaft, and an overrunning coupler is connected between the shaft sleeve and the middle shaft; and the overrunning coupler can adjust an overrunning torque value by adjusting friction force, and a motor is protected by setting according to the overrunning torque value. When the output torque is smaller than a setting value of the overrunning clutch, the shaft sleeve and the middle shaft rotate at the same time, and the middle shaft is meshed with an output shaft to achieve output; and when the output torque is larger than the setting value of the overrunning clutch, the shaft sleeve idles on the middle shaft, and damage to the motor is avoided.
