Abstract
The invention discloses a hub and key bush integrated power head, relating to the field of machinery, in particular to the technical field of manufacture of power heads of rotary drilling rigs. The hub and key bush integrated power head comprises a hub and a key bush, wherein the hub and the key bush are arranged into a whole, one side of the hub is fixedly connected with a rotary supporting gear, the key bush is externally provided with a hydraulic motor with a speed reducer, an output end of the speed reducer is connected with an input shaft which is provided with an input shaft gear, and the input shaft gear is meshed with the rotary supporting gear. According to the power head disclosed by the invention, on the premise of guaranteeing a working effect, a sleeve is omitted, so that the component constitution of the power head is simplified according to the arrangement in such a way, production steps are reduced, and thus, the power head is simpler to produce and is also reduced in production cost.
Description
Technical field
The present invention relates to mechanical field, particularly the manufacturing technology field of rotary digging drill power head.
Background technology
Existing unit head comprises wheel hub (sleeve), key cover, coaxial being fixed in the described wheel hub (sleeve) of described key cover, periphery at described wheel hub is fixedly connected with gear ring, described gear ring is fixedly mounted on revolution and supports, the power shaft that cooperates with gear ring in a side setting of described casing; This power head structure is complicated, manufactures complexity, and manufacturing cost is high.
Summary of the invention
The invention provides a kind of wheel hub, key cover integrated power head, it is complicated that purpose is to solve existing power head structure, and manufacturing process is poor, the defective that manufacturing cost is high.
