(c) high-iron orbital-band decelerator electric power application.high-wire orbits, both sides of the line, need to also bring aretarder, and make sure to use the k seriesGeared motorIt was more appropriate, and ultimately, the K-series cortex gear decelerator was selected. The option has a special requirement: it is to be used at low temperatures in the Harbin high iron orbit at minus 40°C. Frozen, low-temperature oils are used at ambient temperatures -40 ~50 °C and at low temperatures. Following repeated accounting parameters by the Ministry of Engineering, it was recommended that the client choose not to use the low- power machine, which would require the use of our 1400rpm switch. The final formula is determined as follows: electric retrenchors (freezing anti-40°C at the time of release) parameters: Model: KAF87RF57, power: 0.18KW, output turning: 0.56r/min, output twist: 2560N.m, movement ratio: i 2371, usage factor K: 1.05, Fr: 27400N。
