圆锥渐开线齿轮(斜面体齿轮)被用于交叉或倾斜轴变速器和平行轴自由侧隙变速器中。圆锥齿轮是在齿宽横断面上具有不同齿顶高修正(齿厚)的直齿或斜齿圆柱齿轮。这类齿轮的几何形状是已知的,但应用在动力传动上则多少是个例外。ZF公司已将该斜面体齿轮装置应用于各种场合:4WD轿车传动装置、船用变速器(主要用于快艇)、机器人齿轮箱和工业传动等领域。斜面体齿轮的模数在0.7mm-8mm之间,交叉传动角在0°-25°之间。这些边界条件需要对斜面体齿轮的设计、制造和质量有一个深入的理解。在锥齿轮传动中为获得高承载能力和低噪声所必须进行的齿侧修形可采用范成法磨削工艺制造。为降低制造成本,机床设定和由于磨削加工造成的齿侧偏差可在设计阶段利用仿真制造进行计算。本文从总体上介绍了动力传动变速器斜面体齿轮的研发,包括:基本几何形状、宏观及微观几何形状的设计、仿真、制造、齿轮测量和试验。
Conical involute gears (bevel gears) are used in crossover or tilt axis transmissions and in parallel axis free-lash transmissions. Bevel gears are spur or helical spur gears with different tip crest correction (tooth thicknesses) on the tooth width cross section. The geometry of such gears is known, but how many are applied to power transmissions is an exception. ZF has applied the bevel gear to a variety of applications: 4WD sedan transmissions, marine transmissions (mainly for speedboats), robotic gearboxes and industrial drives. Bevel gear modulus of 0.7mm-8mm, cross-drive angle between 0 ° -25 °. These boundary conditions require a deep understanding of the design, manufacture and quality of bevel gear. In the bevel gear drive in order to obtain high load carrying capacity and low noise must be carried out by tooth profile grinding Fancheng law grinding process. To reduce manufacturing costs, machine settings and tooth-side deviations due to grinding can be calculated using simulation during the design phase. This paper introduces the research and development of bevel gear of power transmission transmission as a whole, including the design, simulation, manufacture, gear measurement and test of basic geometry, macro and micro geometry.
