福尔柯克轮 模型视频 {:4_184:}
Structure
结构
Two opposing arms extending 15m beyond the central axle.
Diameter: 35m
Shape: a Celtic-inspired, double-headed axe.
福尔柯克轮直径为35米,两臂各长15米,形状类似于一只双头斧子。
Mechanism
机械
A gearing mechanism using three large identically sized gears connected by two smaller ones ensures that they turn at precisely the correct speed and remain correctly balanced.
3个大齿轮和2个小齿轮通过外齿咬合,形成可以转动的齿轮链。
Two diametrically opposed water-filled caissons, each with a capacity of 250m3 are fitted between the ends of the arms.
两臂中各有一个相同的储水槽,每个储水槽的空间大约为250立方米。
When the motor rotates the central axle, the arms swing and the small gears engage the central gear, which results in the smaller gears rotating at a higher speed than the wheel but in the same direction.
当电机驱动福尔柯克轮转动时,2个小齿轮围绕中间的大齿轮转动。
两臂的大齿轮在小齿轮的咬合下,也随之自转,保证了储水槽的稳定及其内部液面水平。
The large central gear is fitted loosely over the axle at its machine-room end and fixed in place prevent it from rotating.
中间的大齿轮是固定不转动。
Torsional Moment and Archimedes Principle
力矩平衡和阿基米德原理是理解其运行的关键
If M1 = M2 , and as their directions are reverse, M motor will be small.
M1等于M2时,由于M1和M2方向相反,因此只需要很小的Mmotor,就可以实现转动。
It takes just 22.5 kw to power ten hydraulic motors, which consume just 1.5kwh (5.4 MJ) per half-turn, roughly the same as boiling eight kettles of water.
福尔柯克轮每转动半圈,仅相当于使用了烧开8壶水的能量。
