齿轮尺寸大小的分类,按日本齿轮工业协会(JG-MA)的规定,以模数大于12或节圆直径大于1250mm者为大型齿轮。本文从切齿和磨齿等实际加工出发,介绍了这些大型齿轮的加工过程.一、主要设备大型渗碳淬火齿轮的主要制造设备,以日本大阪制锁造机公司为主介绍如下。1)恒温室大型齿轮在切齿和磨齿时,生产周期很长,如果昼夜之间温差为8℃左右,则在加工过程中会因齿轮坯料和机床热胀冷缩,致使滚切时在齿宽方向,插削和磨削时在圆周方向产生齿厚不均匀.为此,精密加工大型齿轮时,切齿机和磨齿机必
Gear size classification, according to the Japan Gear Industry Association (JG-MA), to modulus greater than 12 or pitch circle diameter greater than 1250mm were large gear. In this paper, starting from the actual processing such as gear cutting and grinding, introduced the processing of these large gears.One, the main equipment Large carburizing and quenching gear of the main manufacturing equipment, Japan’s Osaka-based locking machine company mainly introduced as follows. 1) large-scale greenhouse temperature gear cutting and grinding teeth, the production cycle is very long, if the temperature difference between day and night is about 8 ℃, during processing due to gear blanks and machine tool thermal expansion and contraction, resulting in hobbing when the tooth Width direction, insert cutting and grinding in the circumferential direction of uneven tooth thickness.To this end, precision machining of large gear, gear cutting machine and grinding machine will
