Manual-shift speed reducer of crowned-gear clutch for large-size petroleum drilling machines

Abstract

The invention discloses a manual-shift speed reducer of a crowned-gear clutch for large-size petroleum drilling machines, which comprises a case, an input shaft system, an output shaft system, a shift operating mechanism, a lubricating system, a ventilator system and a measuring rod system. A lower case, a middle case and an upper case are assembled from bottom to top vertically to form the case, the input shaft system, the output shaft system, the shift operating mechanism, the lubricating system, the ventilator system and the measuring rod system are arranged in the case, the input shaft system is used for inputting power and realizing high revolution speed, the output shaft system is used for outputting torque and realizing low revolution speed, and the shift operating mechanism is used for changing the transmission ratio of the input shaft system to the output shaft system. The manual-shift speed reducer of the crowned-gear clutch for the large-size petroleum drilling machines has wide applicable range of environmental temperature, is capable of running on open sites full time, is wide in applicable range of environmental temperature and has the advantages of high bearing capacity, long service life, large output torque, high transmission efficiency, low operation noise and vibration of the case, fine tightness, high exchangeability, convenience in installation, flexibility and stability in shift.

Description

technical field [0001] The invention relates to the technical field of reducers, in particular to a manual gear shifting drum gear clutch reducer for driving a turntable of a large oil drilling rig. Background technique [0002] The rotary table drive of oil drilling rigs is used for manual gear shift drum tooth clutch reducer to realize the rotation of the driven rotary table. When the screw drilling tool is drilling, bear the reaction moment on the drill string; (3) bear the weight of the pipe string when tripping or running the casing, and unload the drill pipe buckle when tripping the drill pipe: (4) adjust and control when drilling directional wells The azimuth of the downhole drill bit. [0003] Due to the low power transmission, low reliability, high noise and high vibration and low efficiency, the traditional reducer for rotary table drive of oil drilling rig cannot meet the requirements of high-performance rotary table drive reducer for oil drilling and production ...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is: in order to overcome the low power, low reliability, high noise and large vibration, serious oil leakage and low transmission efficiency of the existing oil drilling rig turntable drive reducer, which is not suitable for deep oil drilling. The problem of using the rotary table drive of the drilling rig, the present invention provides a large-scale oil drilling rig rotary table drive manual gear shift drum gear clutch reducer with high power, high reliability, low noise, small vibration, no oil leakage and high efficiency
