Abstract
An integrated power head with a hub and a key sleeve relates to the field of machinery, in particular to the field of the manufacturing technology of power head of rotary drilling rigs. The integrated power head comprises the hub and the key sleeve, wherein the hub and the key sleeve are integrated; a swing support gear is fixedly connected with one side of the hub; a hydraulic motor with a reducer is arranged outside the key sleeve; an input shaft is connected to the output end of the reducer; and a gear is arranged on the input shaft and meshed with the swing support gear. Under the premise that the operation effect of the power head is guaranteed, a sleeve pipe is eliminated, which simplifies the parts of the power head, the production and the manufacture, and reduces the production procedure and the production cost.
Description
