20.500.12556/RUL-153523 Razvoj naprave za testiranje razleta lamel na komutatorju Development of a device for testing the spread of slats on a commutator V podjetju Domel d. o. o. je velik del proizvodnje namenjen komutatorjem, zato je pomembno, da na komutatorjih naredimo čim več različnih testiranj in s tem poiščemo možne napake, ki lahko ogrozijo delovanje komutatorja v elektromotorju. Eden izmed teh problemov je razlet lamel, ki se lahko pojavi pri visokih vrtilnih in temperaturnih obremenitvah. V podjetju je trenutno prisotna naprava za testiranje z jekleno žico, ki prenaša vrtljaje in navor iz elektromotorja na preizkušanec. Z njo imamo kar nekaj težav, saj se zelo pogosto prelomi, tudi ob najmanjšem tresljaju. V diplomskem delu smo predstavili konstruiranje in izdelavo naprave za testiranje z magnetno sklopko, ki obvaruje elektromotor pri nenadnih spremembah vrtilnega momenta, ter je veliko priročnejša za montažo in demontažo preizkušancev iz naprave. V diplomskem delu smo predstavili rezultate testiranja, ugotovitve in predloge za nadaljnje delo. In the company Domel, a large part of the production is intended for commutators. Therefore, it is important to perform as many different tests as possible in order to find possible faults that would jeopardize the operation of commutator in the electric motor. One of the problems is the scattering of the slats. This can occur at high rotational and temperature loads. The company already has a testing device with a steel rod, which transmits revolutions and torque from the electric motor to the tester. We have quite a few problems with it, as it breaks very often, even with the slightest vibration. The thesis presents the design and manufacture of testing devices with a magnetic clutch, which protects the electric motor in the event of sudden changes in torque, and at the same time it is a much more convenient for the assembly and disassembly of testers from the devices. The final part presents the results of testing, findings and suggestions for further work. komutator razlet komutatorja magnetna sklopka masno uravnoteževanje lamelni skok temperaturna komora commutator scatter of commutator magnetic coupling mass balancing lamellar jump temperature chamber true false false [G.
