Apparatus for online monitoring heavy load abrasion of tooth type coupling

Abstract

An on-line detection unit of heavy load worn out on tooth form coupler is prepared as fixing metal contact plate of detector on driving shaft of said coupler and elastic contact on driven shaft of coupler, connecting metal contact with elastic contact with each other when coupler is operated normally, picking up preset worn out limitation signal by utilizing gas displacement when driving and driven shaft are on heavy load and utilizing said limitation signal to control alarm circuit through switching circuit for making alarm circuit launch out alarm signal.

Description

technical field [0001] The invention relates to transmission components in large or heavy machinery, more specifically to an on-line monitoring device for heavy-duty wear of gear couplings. Background technique [0002] Large-scale mobile lifting equipment and heavy machinery, such as ship loaders and ship unloaders at port terminals, have special components for the connection of power and load, that is, couplings. Please see FIG. 1 , the main functions of the shaft coupling 10 are: 1. Realize the connection between the power source 11 and the load 12 . 2. Realize the centering and balance of the axis operation of the power shaft and the load shaft. 3. Instantaneous buffering effect. It is a coupling device widely used in the motor of mechanical transmission and the high-speed shaft of the reducer, and 13 is a brake. [0003] Due to the bridge function between the coupling and the load end, the degree of wear (hidden danger) of the coupling is related to the operation saf...

Problems solved by technology

Therefore, listening to whether there is an impact noise is judged based on the subjective experience of the person, and it varies from person to person, so it is impossible to talk about the accuracy of monitoring.

However, it is time-consuming and inefficient to disassemble and disassemble the coupling after stopping the machine, and it affects daily production.

In addition, the shutdown inspection can only be carried out visually under static conditions. It can only be identified at the power end and load end of the coupling by using the method of turning the coupling, and checking the displacement degree of the ring gear sleeve to estimate the coupling. degree of gear wear

That's all, it must rely on rich accumulated experience, and it also has subjective judgments. The accuracy of spot inspection is very poor, and novices can't confirm it at all.

Therefore, the traditional point inspection has one of the biggest defects; that is, the real-time dynamic monitoring of the coupling cannot be realized
