Embodiment Construction

[0057] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0058] A control system for a chain drive tensioner includes: an acoustic emission detection unit, a motion control unit, a position detection unit, a comparison unit, a display unit and a PLC control system.

[0059] The acoustic emission detection unit is used to collect the acoustic emission signal generated in the chain drive process, and transmit the collected signal to the control computer 22; the motion control unit is used to control the tensioning motor and the braking motor, and then control the braking mechanism 5 and the tensioning motor. The tightening mechanism 2 starts and...

Abstract

The invention provides a control system and method for a chain transmission tensioning device, which is used to control the chain transmission tensioning device to solve the problem of chain slack during the chain transmission process. The control system specifically includes an acoustic emission detection unit, a motion control unit, a position detection unit, a comparison unit, a display unit and a PLC control system. Among them, the acoustic emission detection unit is used to collect the acoustic emission signal generated during the chain transmission process; the motion control unit is used to control the tensioning motor and the brake motor; the position detection unit is used to control the displacement stroke of the braking mechanism and detect the rotation of the tensioning mechanism The comparison unit and the display unit are used to compare and display relevant data respectively; the PLC control system includes a feedback module, a delay module and an early warning module, and the early warning module is used to estimate the remaining service life of the chain and remind the staff to replace the chain. The control system and control method can quickly, effectively and accurately control the chain transmission tensioning device to solve the chain slack problem.

Description

technical field [0001] The invention belongs to the field of mechanical transmission control, and in particular relates to a control system and method for a chain transmission tensioner. Background technique [0002] The chain drive tensioning device is used to solve the problem of chain slack in the chain drive process. The instantaneous speed of the chain drive is unstable, and it has certain impact, vibration and noise. As a result, the contact between the chain and the sprocket may fall off, the transmission efficiency is reduced, and even mechanical failures occur. Such problems can be solved to a certain extent by the tensioning device. [0003] At present, most of the tensioning devices used are manual control, and the shortcomings of manual control are mainly artificial control of the tensioning degree, no quantification function, and large labor cost investment; and most of the tensioning devices currently using automatic control use spring control. The degree of t...
