Abstract

The invention discloses a speed-variable and torque-reducing transfer case, which comprises a case body, wherein a power input shaft, a gear transmission mechanism, a first intermediate shaft and a power output shaft are arranged in the case body, and one end of the power input shaft protrudes The housing, the gear transmission mechanism is provided with two power output shafts, which are respectively the first power output shaft and the second power output shaft, and each of the first power output shaft and the second power output shaft extends out of the box body. Aiming at the characteristics of tight space and limited load on the offshore drilling platform, the present invention provides a speed-changing and torque-reducing transfer case that integrates a gearbox, a torque-reducing case, a transfer case, and a forward and reverse gear case. The transfer case has compact structure, short transmission chain, light weight and low cost.

Description

technical field [0001] The invention relates to the technical field of mechanical transmission, in particular to a speed-variable and torque-reducing transfer case applied to an ocean workover rig. Background technique [0002] The transmission part of the workover rig is generally powered by a diesel engine or an electric motor, through a gearbox, a transfer case, and then through a main gearbox or a sprocket box to drive the drawworks; The forward and reverse gear box is used to drive the turntable operation. Since the existing transfer case cannot realize the functions of speed change and positive and negative rotation, when driving the winch and the turntable, a gearbox and a positive and negative gear box are also required. The use of space and carrying capacity of offshore drilling platforms is limited, and the cost is high, so there are restrictions on the footprint and weight of offshore workover rigs. Contents of the invention [0003] In order to solve the abov...
