In order to enhance the load capacity of gears, researchers take notice in the asymmetric tooth gears. Asymmetric gear which has higher pressure angle of back tooth aiming to improve banding strength has been analyzed (Deng, et al., 2003). Brown et al. (Brown, et al., 2010) investigate the asymmetric tooth from both point of view of bending and scuffing.(More)
In this paper, we describe a novel low backlash reducer using precessing crown gears. we call this mechanism Crown Reducer. The features of this reducer are low backlash, high reduction ratio, advantage in miniaturizing. These features greatly contribute to design various small mechanisms such as a finger joint of a robot hand. The crown gear pair is(More)
