EN The advantages of heat-sealable belts include: the possibility of welding of their ends (allows obtaining a strip of any length and a quick replacement in case of damage), excellent resistance to abrasion, resistance to oil, grease, dirt and some chemicals, resistance to temperatures from −30 °C to +80 °C, significant elasticity at a relatively low level of stretching, high value of the friction coefficient (thus very good anti-slip properties even at load changes), safety when in contact with food. There are few publications devoted to these belts, therefore the authors have built a test stand for experimental studies of such drives. The analysis of vibration of a draw gear with a thermally sealed belt was carried out in accordance with the assumptions of an active experiment. The following input parameters were adopted: belt tension force, torque loading the gearbox, rotational speed of the drive shaft. The following output parameters were adopted: the values of vibration acceleration of selected elements of the test stand (the transducers are mounted on the bearing housings of the drive and the driven shafts). During the research, the load of the gearbox was changed and the influence of its impact on the value of the point measures of vibration signals was observed. The following point measures were analyzed: the RMS value, the peak value and the kurtosis. The results of the research will certainly be useful for designers and technicians involved in the operation of drawstring drives with thermally weldable belts.
