Abstract

The invention discloses a connecting device, and belongs to the field of transmission devices. The connecting device comprises a key sleeve, an expanding sleeve, a flywheel and a flywheel shell, wherein one end of the key sleeve is connected to an input shaft of a speed reducer through a key, the other end of the key sleeve is connected to an output shaft of a motor through a key, the expanding sleeve is fixed to the outer wall of the key sleeve, the flywheel is fixed to the expanding sleeve, the flywheel shell is arranged outside the flywheel and is fixedly connected to a shell of the motor, and the inertia value of the flywheel is greater than five times of the inertia value of the motor but smaller than ten times of the inertia value of the motor. According to the connecting device, the flywheel is used for improving inertia matching, the impact of the return clearance of the motor to a transmission system is controlled within the permitted range, the impact force caused by the return clearance is greatly reduced, and therefore parts on the transmission system are prevented from being damaged by frequent impact, the motor, the speed reducer and other transmission mechanisms are protected, and the system is protected against unpredictable breakdowns.

Description

technical field [0001] The invention relates to the field of transmission systems, in particular to a connecting device. Background technique [0002] The active compensation system realizes the closed-loop control of displacement, speed and force by actively controlling the drive unit. Due to the interference of irregular movement of ocean waves, many deep-sea operation equipment need to have the function of active compensation control to offset the interference of ocean waves on equipment. Typical examples include active heave compensation cranes for deep-sea operations and active tension compensation for deep-sea operations. Active compensating tensioners for towing winches and deep sea operations. [0003] In the driving unit with active compensation function, the typical driving scheme is to use the secondary control hydraulic motor + planetary reducer to drive the execution unit. Through closed-loop control of the secondary control hydraulic motor, various functions o...
