Abstract

The invention provides a novel oil field drilling rotating disc transmission case. The novel oil field drilling rotating disc transmission case comprises an output shaft; a brake disc connecting sleeve is arranged on one side of the output shaft; and an output shaft universal joint connecting disc is fixedly mounted on the other side of the brake disc connecting sleeve through bolts. According to the novel oil field drilling rotating disc transmission case, a disc type device is adopted for braking, the braking torque can be adjusted, the novel oil field drilling rotating disc transmission case is directly mounted on the brake disc connecting sleeve at the rear end of the output shaft, a braking torque transmission path is shortened, and the mechanical transmission efficiency is improved. The novel oil field drilling rotating disc transmission case has a transmission clutch function, a forward and reverse turning switching function, a braking function and the like, is complete in function, reasonable in structure, compact in appearance, convenient to install and capable of saving space, in a disc type clutch device, an air bag is adopted to replace an existing air cylinder piston to push a friction plate to be separated and combined, the production and mounting technology is simplified, the machining difficulty is reduced, and the production cost is reduced.

Description

technical field [0001] The invention relates to the field of oil field drilling, in particular to a novel oil field drilling rotary table transmission box. Background technique [0002] The vehicle-mounted drilling rig is a relatively new loading form of drilling machinery and equipment. It integrates the main drilling equipment and drilling tools into one vehicle, and usually performs drilling operations on the vehicle. [0003] Most of the oil mining areas are located in plateaus, deserts, wetlands, swamps and water surface areas. Due to the geographical environment, these places require the input shaft mechanism and output shaft mechanism of the turntable transmission box of the vehicle-mounted drilling rig to be located in different boxes to realize power transmission. The input shaft mechanism and the output shaft mechanism adopt a separate box design, so it is difficult to guarantee the oil tightness of the turntable transmission box. [0004] At present, the traditio...
