目前,在低速,高力矩传动领域中,增添了一种基于新的设计概念的液压马达。这种马达基本上是由一轴向活塞液压马达和一谐波齿轮减速传动装置组合而成,此传动装置由一旋转齿轮所构成,(如图)。该旋转齿轮比与其相对的固定齿轮多一个齿。液压活塞施力于旋转齿轮的表面,使它绕着与其相啮合的固定齿轮动进。这种动进作用就产生一很大的减速比。其减速比由两个齿轮的齿数来确定。例如,如果旋转齿轮为31个齿,固定齿轮为30个齿,
Currently, in the field of low-speed, high-torque transmission, the addition of a new design concept based on the hydraulic motor. This kind of motor is basically a combination of an axial piston hydraulic motor and a harmonic gear reduction transmission. The transmission consists of a rotating gear (as shown). The rotating gear has one more tooth than its opposite stationary gear. The hydraulic piston applies a force on the surface of the rotating gear to make it move around the fixed gear engaged therewith. This move to produce a large reduction ratio. The reduction ratio is determined by the number of teeth of two gears. For example, if the rotating gear is 31 teeth and the fixed gear is 30 teeth,
