Ideal Gear Constraints and Gear Ratios

这GydF4y2Ba环形行星GydF4y2Ba块对三个连接的轴施加了一个运动学和一个几何约束：GydF4y2Ba

${rGydF4y2Ba}_{rGydF4y2Ba} ω_{rGydF4y2Ba} =GydF4y2Ba {rGydF4y2Ba}_{CGydF4y2Ba} ω_{CGydF4y2Ba} +GydF4y2Ba {rGydF4y2Ba}_{pGydF4y2Ba} ω_{pGydF4y2Ba}$

${rGydF4y2Ba}_{rGydF4y2Ba} =GydF4y2Ba {rGydF4y2Ba}_{CGydF4y2Ba} +GydF4y2Ba {rGydF4y2Ba}_{pGydF4y2Ba}$

这ring-planet gear ratio is

${GGydF4y2Ba}_{RPGydF4y2Ba} =GydF4y2Ba {rGydF4y2Ba}_{rGydF4y2Ba} /GydF4y2Ba {rGydF4y2Ba}_{pGydF4y2Ba} =GydF4y2Ba {nGydF4y2Ba}_{rGydF4y2Ba} /GydF4y2Ba {nGydF4y2Ba}_{pGydF4y2Ba} ，，，，GydF4y2Ba$

在哪里GydF4y2BanGydF4y2Ba是每个齿轮上的牙齿数。就该比率而言，关键的运动学约束是GydF4y2Ba

${GGydF4y2Ba}_{RPGydF4y2Ba} ω_{rGydF4y2Ba} =GydF4y2Ba ω_{pGydF4y2Ba} +GydF4y2Ba （（GydF4y2Ba {GGydF4y2Ba}_{RPGydF4y2Ba} -GydF4y2Ba 1GydF4y2Ba ）GydF4y2Ba ω_{CGydF4y2Ba} 。GydF4y2Ba$

这Three degrees of freedom reduce to two independent degrees of freedom. The gear pair is (1, 2) = (pGydF4y2Ba，，，，GydF4y2BarGydF4y2Ba）。GydF4y2Ba
