Slipping monitoring protective device of marine gearbox clutch

Abstract

The invention relates to a slipping monitoring protective device of a marine gearbox clutch. The protective device comprises a rotating speed sensor; the protective device is characterized in that the clutch is arranged on an input shaft in a gearbox; a PLC controller, an alarm, a driving side rotating speed sensor and an output side rotating speed sensor are configured in a ship driving mechanism, wherein the driving side rotating speed sensor is located at an input side of the clutch; the output side rotating speed sensor is located at an output side of the gearbox; rotating speed analog quantity signals / switch quantity signals of the driving side and the output side, acquired by two rotating speed sensors, are respectively imported into different signal input ends of the PLC controller; when the rotating speed analog quantity signal / switch quantity signal at the output side rotating speed sensor is 2% lowered than that at the driving side rotating speed sensor, a host is directly controlled through a data line after the processing of the PLC controller, the rotating speed of the host is lowered, a new balance is achieved, and if the balance cannot be achieved, the alarm of the clutch gives out a slipping signal after time delay.

Description

technical field [0001] The invention belongs to a monitoring protection device for a gearbox clutch. In particular, the invention relates to a slip monitoring and protecting device for a clutch of a marine gearbox, which belongs to the field of marine machinery and equipment. Background technique [0002] Ocean transportation is the most important mode of transportation in international logistics. It refers to a way of using ships to transport goods between ports in different countries and regions through sea lanes. More than 2 / 3 of the total international trade volume. The advantages of ocean transportation are its large volume, low shipping costs, and well-connected waterways. Due to the mass production of medium and high-speed marine diesel engines, the same marine clutch gearbox is required. [0003] Due to the challenge of low cost, the lightweight design of marine gearboxes is becoming more and more important, requiring marine gearboxes to become lighter and lighter...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to aim at the fact that the marine gearbox clutch is prone to slipping when used in harsh environments, or the clutch is crawling. If the ship is not dealt with in time during the voyage, the light ship will temporarily lose propulsion power, and the severe case will To solve a series of problems such as burning the clutch plates, the power of the main engine cannot be transmitted to the paddle valley, and the ship completely loses power, and a series of problems such as a marine gearbox clutch slip monitoring and protection device are provided.
