Distinguished with some basic theory and approaches of traditional tooth surface design, the spiral bevel gear with new tooth surface, namely spherical involute tooth surface, is investigated. Firstly, it improved its formational principle based on the spherical involute theory. As a key part, the parametric equation of the generating line was made a detailed derivation. To this end, fast and a...

In this contribution we present the novel electro-pneumatic adaptable impedance actuator (EPAIA) consisting of a brushless DC-motor and a rotational pneumatic actuator, applied in series to the gear train. The pneumatic actuator is employed as a pneumatic torsional spring with a continuously adaptable stiffness, controlled by air inflow and pressure control. Thus, a rotary variable stiffness ac...

Abstract: In this paper, a new mechanism was developed as a gearbox for power transmission between concentric shafts. With this approach, reduction ratios range from 10:1 to millions to one is possible for single-stage. This mechanism is very cheaper than planetary gears. The mechanism consists of one drive shaft and one driven shaft, conical gears which one of them is fixed and the others are ...
