在汽车和拖拉机、林业机械、工程机械等机器的传动齿轮中,有部分采用短齿或双模数(双径节)齿轮。这些齿轮在单件小批生产时,齿轮的加工有一定困难。因为大量生产时这类齿轮是采用专用齿轮刀具加工的。在中小型企业,都较缺少各种规格的短齿和双模数(双径节)齿轮刀具。以往对于这些齿轮的制造与修理,一般采用样板刀加工,也采用手工锉修后用样板检验。齿轮的加工效率低,修造质量也达不到要求。这里介绍用标准通用齿轮刀具加工短齿和双模数齿形的方法,供大家参考。
In the transmission of gears for automobiles and tractors, forestry machinery, construction machinery and other machines, some use short-toothed or dual-modulus (double-diameter) gears. These gears in a single small batch production, the gear processing have some difficulties. Because of the mass production of such gears is the use of special gear cutter processing. In small and medium-sized enterprises, are short of a variety of short-tooth and dual-modulus (double-diameter section) gear cutting tools. In the past for the manufacture and repair of these gears, the general use of model knife processing, also used manual file repair model test. Gear machining efficiency is low, the quality of construction also failed to meet the requirements. Here is the use of standard general-purpose gear cutter processing short teeth and double-modulus tooth method for your reference.
