Measurement Technique for Temperature of Friction Lining of Brake Roller for Pallet Flow Rack

One of the types of high-density storage systems is a pallet flow rack. A brake roller is one of the safety elements of pallet flow racks, which is necessary to limit the speed of transportation of the pallet. The design of the most common construction of such brake roller is closed and maintenance-free. Therefore, it is important to increase the service life of the brake roller; one of the determining factors of which is the temperature of the friction lining. This article presents a measurement technique for determining the temperature of the friction lining of the centrifugal brake of the roller. For this purpose, a stand-alone measuring unit has been designed to transmit the readings of a K-type thermocouple mounted in one of the linings via a radio signal. An experiment was performed to determine the temperature conditions of the friction lining for a sample of the brake insert for a different number of braking per hour. According to the obtained data, the temperature of the friction lining during the braking process does not exceed 28–33 °C. Thus, having experimental data on the temperature mode of the operation of the friction lining, it is possible, based on known tribological characteristics of material of lining, to evaluate the operability and operating life of the friction pair of the brake roller.
