Description

The belt tension meter is an optically measured maintenance tool for determining the belt tension or belt tension. This belt tension measuring device consists of a display device and a sensor head that is attached to a gooseneck. The advantage of the swan neck is that the sensor head can be positioned flexibly. Due to the mobility of the swan neck, the sensor can also measure the belt tension (trumload) at inaccessible places. The belt tension gauge measures the belt's trumload and belt frequency when the belt is stationary. A small pulse on the belt, vertical to the tension direction, is sufficient to swing the belt. The belt tension measuring device uses the sensor to record the natural frequency of the belt generated in this way and visualizes it on the display. The belt tension measuring device can directly determine the actual tension force of the belt from the belt frequency and the optionally entered belt length and belt mass. However, it is not absolutely necessary to enter this data in order to carry out measurements directly with the belt tension measuring device. The measuring units can be switched in the belt tension measuring device between N (SI unit) and Pound Force (US unit). The graphic display of the belt tension meter always shows the measured value as belt frequency in Hz. If the belt mass and length are entered in the device, the trumforce is also displayed in Newton. The intuitive graphics menu is visualized on the high-contrast display of the Trumkraft measuring device in six selectable languages. For further analysis and quality assurance purposes, the belt tension meter is equipped with a memory. In the memory of the belt tension measuring device up to 750 data records can be stored in 15 orders of 50 measured values. The belt tension measuring device is supplied completely ready for use. The scope of delivery includes the hand-held device, the standard sensor with goose neck, a magnetic holder, batteries and operating instructions. An optional belt tension meter includes a case, a frequency control, a tripod and an external sensor head with spiral cable to increase measurement flexibility.Application areas for belt tension measuring devicesThe belt tension gauge can be used to measure both belt tension of toothed belts and V-belts. Belt tension is an important parameter in the installation, setup, maintenance and repair of belt drives. The belt tension should be checked regularly over the entire runtime and adjusted if necessary to ensure a maximum service life of all machine components. It is important that the pre-load force is selected according to the forces to be transferred. In principle, the greater the forces to be transferred and the greater the belt speed during operation, the greater the pre-tensioning forces must be selected. At the same time, make sure that the belt tension is not set too high, otherwise the bearings of the belt drives can be damaged while the belt is being tightened at the same time was causing belt cracks. If the belt tension is too low, this can also lead to damage if, for example, there are tooth protrusions or the belt slipping. This makes it all the more important to determine the belt tension or the pre-tension force using a belt tension gauge. As a result, consequential costs can be significantly reduced due to unplanned downtimes caused by bearing damage or defective belts. The use of a belt tension measuring device is therefore suitable for applications in the field of motor technology, industrial production, stepper motors, tool and machine construction or also in the field of maintenance and maintenance.Why should the belt tension be measured?The measurement of belts is always necessary when machines and systems are to be optimally maintained. A belt drive only achieves the maximum service life if it is designed for use. This means that the belt is optimally tensioned and the discs are precisely aligned. With the help of the belt tension measuring device, the clamping force (trucking force) can be determined exactly when the belt is stationary.Long service life and high performance of equipment, machinery and equipment - that is the goal of every user, either a company or an individual. Belts are an important and necessary component in many industries, especially on various machines. The smallest deviations from the standard can have serious consequences, such as Sliding or slipping, which causes system failures. was not possible. Therefore, it is particularly important to check the belt tension regularly, since only then can the proper rotation be achieved. Not only a weaker than necessary tension, but also a tension above the norm can cause severe and, was important, temporary deterioration of the belt and performance drop. For example, incorrect belt tension in the vehicle's generator is devastating in both cases and can be dangerous, leading to complete wear and engine damage. Significant costs - are just one of the points in the list of potential problems that can follow. Even if the belt is not cracked, changing its function is not unimportant for the whole system or mechanism, and it is therefore indeed one of the priority tasks to keep this problem under control.This can be achieved easily and precisely with the help of the belt tension meter. With the belt tension gauge, the user can determine the belt tension in the system to be controlled from pulleys and thus take immediate action to adjust the tension to the setpoint. Although the measurement of belt tension requires high precision, the task is greatly simplified for the user due to the design and specifications of the meter. The belt tension gauge is digital and the sensor attached to the gooseneck of the meter measures the tension based on the sound waves produced by the belt. Manual testing of the voltage is therefore no longer necessary. The best way to determine belt tension is to use the meter and use the calculations to obtain accurate data on the belt tension. The vibrations/vibrations generated by the belt are not only registered by the measuring device, the data is processed after they have been received by the sensor, and based on the characteristics of the drive belt (weight, width, length) the final result is calculated and displayed on the illuminated screen (in Newton/Hz).The range of applications of the belt tension measuring device is quite large and ranges from the individual applications in the household (various devices and household appliances) or in the office to industrial areas (large motor shaft combinations, various conveyors, hoists, elevators, automotive industry, Agricultural machinery).The advantage of using the belt tension gauge is not only that it helps to detect errors and prevent errors, but can also be used to check the correctness of the installation before commissioning. Before starting the equipment, checking with the belt tension gauge is a reliable confirmation that the machine is running properly according to the regulations. The data received from the belt tension gauge can be saved and later used as a standard pattern during regular maintenance checks. After the measurement in real time, the data is not lost and can be stored in the belt tension measuring device for the coming measurements.When it comes to belts, there are many things to do: Heavy loads, speed, vibration, power, protection of other mechanisms from overload, etc., but the most important thing to remember is safety. The use of the belt tension gauge is a good way to carry out a modern technical service and a diagnosis of faults and mechanical / technical problems. What was the belt tension or belt pre-tensioning force?Since several forces act on one belt drive, the most important forces on belt drives are named in the following to understand the significance of belt tension / preload force. The belt connects a drive pulley to a driven pulley. The drive pulley is driven by a motor which generates a torque and transmits it to the drive pulley. The belt transmits this torque to the driven pulley in the form of circumferential force. The following forces are important.The circumferential force: The circumferential force corresponds to the useful force to be transmitted by the belt. The circumferential force depends on the applied engine power and thus on the torque as well as the engine speed and the pulley diameter. To maintain the balance of forces, the circumferential force causes the formation of different forces in the belt's towers. The difference between the forces between the load and the empty spectrum corresponds to the circumferential force that is transferred to the trim belt.The friction force: The friction force acts on the contact surfaces between the belt and the discs. The frictional force on the drive pulley ensures that the torque of the motor is transferred to the belt and is thus transmitted to the driven pulley. The friction force on the driven pulley transfers the force between the belt and the driven pulley. This produces a usable torque at the driven pulley, which corresponds to the product of circumferential force and half the diameter of the driven pulley.The centrifugal force. The centrifugal force increases at increasing speeds and ensures that the belt stretches and thus loses grip. In this case, the centrifugal force acts against the adhesion force.The pre-tension force: The pre-tension force / trumload / belt tension is different under dynamic conditions in the load and empty range. In the static state, the belt tension is identical in both towers. The pre-tensioning force must be adjusted in the static state so that under dynamic conditions there is sufficient adhesion on the pulleys to ensure the transmission of power from the belt to the pulley while taking into account the centrifugal forces acting on the belt in the operating state. However, the belt tension must not be set too high, otherwise belt damage and/or bearing damage may occur under load. The correct belt tension must be selected specifically for each belt and the appropriate application. Belt manufacturers usually specify the corresponding belt tension in the form of forces or frequencies. With a belt tension gauge, the required belt tension can then be precisely determined after installation and before starting a belt drive.
