Abstract

The invention relates to a reverser which comprises a gear, a spiral bevel gear with a shaft, a first box body, an output shaft, a second box body, a first spiral bevel gear, a first jaw clutch, a second jaw clutch, a third jaw clutch and a second spiral bevel gear, wherein a gear is arranged on the spiral bevel gear with the shaft through a spline, and the output shaft is provided with a second shaft sleeve and arranged in the second box body; the first spiral bevel gear is arranged on the first jaw clutch, gear teeth are meshed with the spiral bevel gear with the shaft, and the first jaw clutch is arranged on the upper end of the output shaft; the second spiral bevel gear is arranged on the third jaw clutch, and the third jaw clutch is arranged at the lower end of the output shaft; and the second jaw clutch is arranged at the middle part of the output shaft through a spline, can slide up and down, and is respectively meshed with an upper jaw clutch and a lower jaw clutch. The reverser provided by the invention has the advantages of reliably realizing the forward and backward rotating function of the output shaft and being low in manufacturing and maintenance cost, strong in adaptability and capable of adapting to harsh work environments of drilling machines.

Description

technical field [0001] The invention relates to a commutator, in particular to a device for realizing reversing on the output shaft of a drilling machine, which belongs to the field of construction machinery (drilling machine). Background technique [0002] The working conditions of the drilling rig are relatively harsh, and its parts and structure are designed on the principle of simplicity and practicality; it is required to be easy to install and disassemble, and easy to maintain, so it is suitable for use in field areas. The commutator on the common mechanical structure has the limitations of complex structure, inconvenient installation and maintenance, so it is not suitable for the power clutch of G-3 drilling rig. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages, thereby providing a kind of commutator, the commutator realizes the output The function of the positive and negative rotation of the shaft final...
