Gear selection of reducerIn the two stage cylindrical gear reducer, the high speed and low speed stage uses straight gear or helical gear Thank you for helping me answer the question, thank you
Heat treatment with 45 hardened gear size, gear hardness can be the same, can also be small gear hardness is higher than the big gear 20~30HB or 2~3 HRC
Quenching and tempering, carburizing, quenching, hardness HRC58~63, general situation with No. 45 steel, Quenched and tempered HB235~275, if the gear larger diameter 100mm above, Quenched and tempered HB225~255, Quenched and tempered surface high frequency quenching HRC48~53 or 40Cr
Now the heat treatment process has improved a lot, and the cost is not high, the soft gear tooth surface has been rarely used, recommend the use of hardened gear reducer to see your application and load and heavy load situations and often start with low carbon and low alloy steel 20Cr, 20CrMo, 20CrMoV etc.,
