Small-size underground high-power transmission mechanism

Abstract

The invention relates to a small-size underground high-power transmission mechanism. The small-size underground high-power transmission mechanism comprises a motor; an output shaft of the motor is connected with a planetary reducer; the output end of the planetary reducer is installed on one side of a coupler; a shaft on the other side of the coupler is connected with a left crawling arm and a right crawling arm; and the motor, the planetary reducer and the coupler are all installed on a rack. According to the small-size underground high-power transmission mechanism, by arranging sliding rods,clamping grooves, hollow gear rings, the left crawling arm, the right crawling arm and the crawling wheel, when a tooth on the surface of a transmission gear is greatly abraded, a user pulls the corresponding sliding rod out of the corresponding clamping groove and changes a new hollow gear ring, and therefore the whole transmission gear does not need to be replaced; economic investment needed bychanging the whole transmission gear is lowered; in addition, the transmission mechanism is mainly composed of the planetary reducer, a right-angle reducer and a parallel shaft reducer, so that the structure is compact; large reduction ratio and large torque transmission can be achieved in a small space; full-closed design is adopted; the service life is long; the maintenance cost is low; and thepracticability is high.

Description

technical field [0001] The invention relates to the technical field of transmission mechanisms, in particular to a small-sized downhole high-power transmission mechanism. Background technique [0002] In order to solve the transportation problem of downhole equipment in horizontal wells and highly deviated wells, especially for perforation, production wells, post-casing logging and downhole operations, etc., high-power conveyors are needed to transport logging tools, perforating guns, etc. to the downhole Work in horizontal section. [0003] Due to size limitation, the existing reducer equipment is mostly open structure, and the gears, bearings and other parts are not sealed. After each downhole, it needs to be cleaned and replaced with new parts. It is troublesome to use, and the reduction ratio and torque transmission are relatively complex. Small, and the gears in the reducer are prone to wear due to high friction during actual use. When the teeth of the gears are damage...
