Problems solved by technology

[0003] The speed is large, the cranking efficiency is low, and this operation lacks the interlock function with the diesel engine starting system, which has potential safety hazards
Although some high-configured diesel engines will be equipped with pneumatic or electric cranking mechanisms, the cost is high, and the fishing and some marine machinery markets are unacceptable.

Abstract

The invention provides a marine diesel turning mechanism which comprises a motor, a box body, an output flange, an output shaft, a worm gear and a worm, wherein the output shaft, the worm gear and the worm are mounted in the box body; one end of the worm is in gear transmission with a motor output shaft, and a handwheel is mounted at the other end of the worm; the worm gear is mounted on the output shaft, and the output end of the output shaft penetrates the box body, is mounted in the output flange and is sleeved with a sliding gear; a shifting fork component is mounted on the output flange and comprises a fork arm, a sensing device and a positioning device, the fork arm can push the sliding gear to axially move on the output shaft, the sensing device can sense the position of the sliding gear, and the positioning device can lock the fork arm to limit the position of the sliding gear; and the sensing device is connected with a control system of the motor and can control the start or stop of the motor according to the change of the position of the sliding gear.

Description

technical field [0001] The invention belongs to the technical field of marine diesel engine cranking, and in particular relates to a marine diesel engine cranking interlocking mechanism. Background technique [0002] During the assembly, test run, overhaul and start-up process of the existing medium-speed marine diesel engine after a long shutdown, it is necessary to use the cranking mechanism to turn the flywheel to realize the timing adjustment and coupling adjustment of the diesel engine. Diesel engines and some marine main engines are not equipped with a turning mechanism, and only a turning lever of more than one meter is used to pry the flywheel turning, which is labor-intensive [0003] The speed is large, the cranking efficiency is low, and this operation lacks the interlock function with the diesel engine starting system, which has potential safety hazards. Although some high-configured diesel engines will be equipped with pneumatic or electric cranking mechanisms,...
