当需要改变的方向的轴的旋转时，锥齿轮是有用的。它们通常安装在相隔90度的轴，但可以被设计为工作在其他角度。
伞形齿轮有四种类型：
直齿锥齿轮：齿轮有一个圆锥形的间距表面和直齿尖端很细，一个顶点。
零伞形齿轮：非常相似，除了牙齿是弯曲的直齿锥齿轮。
螺旋锥齿轮的齿弯曲的角度，然后允许的接触是渐进的和光滑。
双曲线锥齿轮螺旋锥齿轮除了在球场表面，而不是是双曲面锥齿轮可以防反弹。
他可直齿锥齿轮或螺旋。直齿锥齿轮直齿轮齿实际上有同样的问题 - 每个齿啮合，它会影响相应的牙
就像与直齿圆柱齿轮，这个问题的解决方案是曲线的齿轮齿。这些涡旋齿啮合就像螺旋齿：接触在齿轮的一端开始，并逐步在整个齿传播。

Bevel Gears
Bevel gears are useful when the direction of a shaft's rotation needs to be changed. They are usually mounted on shafts that are 90 degrees apart, but can be designed to work at other angles as well.
There are four types of bevel gears:
Straight Bevel Gears: These gears have a conical pitch surface and straight teeth tapering towards an apex.
Zero Bevel Gears: Are very similar to straight bevel gears except the teeth are curved.
Spiral Bevel Gears: The teeth are curved at an angle which then allows the contact to be gradual and smooth.
Hypoid Bevel Gears: These gears are similar to spiral bevel except that the pitch surfaces are hyperboloids rather than cones and the gears can be anti backlash.
he teeth on bevel gears can be straight, or spiral. Straight bevel gear teeth actually have the same problem as straight spur gear teeth -- as each tooth engages, it impacts the corresponding tooth all at once
Just like with spur gears, the solution to this problem is to curve the gear teeth. These spiral teeth engage just like helical teeth: the contact starts at one end of the gear and progressively spreads across the whole tooth.
What ever you bevel gear you require, Hopwood Gear can supply it!
