Description

A METHOD FOR MONITORING THE POWER TRANSMISSION ELEMENTS Technological Field:

The invention is related to a monitoring method for determining problems such as possible tear, breakage, damage problems previously by monitoring the strain on the belts which is a power transmission element which transmits the motion from one point to another point by means of a set of pulleys in many fields within the industry.

State of the Art: The belts are used widely in machine industry with a wide range such as automotive, hoisting machinery, machine tools etc. Belts help the motion to be transmitted from one point to another point. It is useful for softening the flexible structure and the pulsed power transmissions. The cycle ratios are not stable in places where the belts are used since flat, V, circular type belts can slide. This ratio is stable in toothed belts. Whether it is a normal belt or a tooted belt, in case of breakage, serious financial losses and time losses are experienced. In order to prevent these losses, it is beneficial to keep the pulley health under observation. Especially in internal combustion engines, the time information concerning ignition and similar is provided by means of the toothed belts so that belt breakage means time and financial losses for bringing the system synchronous again.

In current applications the pulley component is subject to high force values during operation. As a result of this effect deformation and breakage can be experienced and can let down the driver since it does not generate an error message previously. It is aimed to eliminate this fault by means of evaluating the strain values received over the pulley by means of the invention subject to the present description.

In the known art, detection of the strain is provided by means of a sensor used on the system. The elements used influences the design parameters (sizes- compactness) of the system in a negative manner. Also the sensor systems are mounted on the belt in a manner such that they would be subject to the negative effects and harmful inputs from the external environment. Additional sensor and related electronic circuit usage increases the costs. Due to the energy requirements of the used elements, an additional battery requirement occurs and thus the energy consumption increases or the battery option makes the solution impossible.

In the Chinese document No CN107202662 which is encountered during the literature research, a system which is related to measuring the strain value of the belts. The design problems which are caused by the sensors in the measurement systems are eliminated by means of embedding a plurality of sensors within the belt. A wireless data transmission can be provided in this manner. However in the used sensor there are high cost elements such as receiver, transmitter, processor etc.

In the PCT patent document No W02007109896 (A1 ) which is encountered during the literature research, a system which uses a wireless method for solving the problems on the belt such as straining, wearing etc., is disclosed. In the system disclosed in this document, a vibration sensor is used; it includes problems in terms of cost and design aspects which would prevent motion.

In the United States patent document No US2012297888 which is encountered during the literature research, a sensor is provided which measures the carriers such as rope and the like. The structure with sensor increases the costs and influences the design in a negative manner. In the United Kingdom patent document No GB2497100A which is encountered during the literature research, there is system which comprises a method for measuring the strain on the belt. However a vibration sensor is used in this system.

In these examined patent applications, mostly different methods are used although a wireless strain data transmission studies concerning belts are made as a research subject, in studies using similar method, the measurements can be made by using an additional sensor. On the other hand in the invention subject to this description, strain measurement will be made by means of using radio frequencies. Also this method will be executed by means of the elements embedded within the belt without requiring an additional sensor.

As a result a new method is required in which the present state of the art is exceeded, disadvantages are eliminated and the power transmission elements are monitored.

Description of the Invention:

In this detailed description, the inventive method for monitoring the power transmission element is described by means of non-limiting examples only for clarifying the subject matter. In the description, in many fields in the industry, a monitoring method is described for determining problems such as possible tear, breakage, damage problems previously by monitoring the strain on the belts (20) which is a power transmission element which transmits the motion from one point to another point by means of a set of pulleys (10). In Figure 1 , a representative view of the pulley (10) and belt (20) system wherein the method for monitoring the power transmission element is used. In the invention, the strain on the belts (20) which transmits the motion coming from the pulley (10) or gears to another pulley (10) or gears are monitored in a wireless manner by means of radio signals continuously. The method is enabled by means of a plurality of wire element (21 ) which are placed within and overall the belts (20) and each act as an antenna and a sensor.

In Figure 2, a sectional view of the belt (20) used in the method for monitoring a power transmission element is given. In the Figure slots (22) are seen in which a plurality of wire element (21 ) and wire elements (21 ) are located within the belt (20) whose sectional view is given. In the invention, wire element (21 ) is placed within the belt (20) in an embedded manner and thus a belt (20) which acts both as a sensor and an antenna transmitting information by means of radio frequency is provided.

In Figure 3, a representative view of the method for monitoring the inventive power transmission element is given. The strain on the wire elements (21 ) located on the belt (20) can be measured by means of the radio signals by a RFID based reader tank circuit (30). There are coil (31 ), capacitor (32) and resistance (33) on the tank circuit (30). When the strain is zero on the belt (20) located around the pulley (10), the strain force on the wire elements (21 ) located within the belt (20) is also zero. When the strain on the wire elements (21 ) and the belt (20) is zero, no change occurs on the resistance (33) on the tank circuit (30). When a force is applied on the belt (20), a resistance (33) change from the wires (21 ) embedded in the belt (20) is experienced. The resistance (33) change can be transferred to a reader after being monitored from the resistance (33) on the tank circuit (30). When a force is applied on the belt (20), a resistance change occurs in the resistance element (33) located in the tank circuit (30). Therefore the force applied to the belt (20) and the strain realized as a consequence thereof is detected in a wireless manner by means of the radio signals. The regions subject to strain of the belts (20) can be detected by means of the inventive method for monitoring the power transmission element. Therefore the regions which can be subject to deformation or can be damaged on the belt (20) are detected previously. The tank circuit (30) remains stable in a region which is not subject to strain; it detects the resistance (33) change formed with the strain effect. The strain formed in the belt (20) is measured by means of the values of the stable coil (31 ) and capacitor (32) elements and the resistance (33) value which is the only variable value. The wire element (21 ) which is under effect during strain acts as an antenna at the same time and functions with a stable frequency, so that it can transmit the perceived value to the reader by means of radio frequency in a wireless manner. Also the wire elements (21 ) act as an antenna and a sensor within the belt (20) allows using the belt (20) in a longer period by means of increasing the strength of the belt (20).
