Produce description

First of all, in terms of product details of large helical gears, the gear teeth are helical and have a certain angle with the axis, that is, the helix angle. The size of the helix angle determines the overlap and smooth movement of the gears performance, usually selected based on work requirements and processing accuracy. In addition, the end face and normal surface parameters of large helical gears are also important product indicators. These parameters affect the transmission efficiency and load-bearing capacity of the gears.
In terms of processing technology, the manufacturing of large helical gears requires multiple processes, including forging, heat treatment, rough machining, finishing, etc. Forging ensures the strength and toughness of the gear, while heat treatment It can eliminate internal stress and improve the wear resistance and corrosion resistance of gears. Rough machining and finishing are to further correct and improve the shape and accuracy of the gear to ensure that it can meet the design requirements.
