二、直齿轮
直齿轮有节轮表面和平行于齿轮轴线的直齿轮，它们用于传递两平行轴间的动力和运动，
三、伞齿轮
伞状齿轮是依据平截头圆锥体分配的。圆柱齿轮的节圆柱成为分圆锥，齿的横剖面的尺寸是不同的。为了方便起见，锥齿轮的大头端部的参数和尺寸作为标准值。习惯上锥齿轮相互作用的轴彼此不是平行的，通常两轴线彼此成为90度。两个相互齿合的齿轮仅仅为了变向或许有一样的齿数，又或者为了改变速度和方向而齿数不同。
四、曲面齿轮
曲面齿轮是锥齿轮的一种情况，特别之处就是两轮轴线垂直但不相交，有一定的偏移位置。

这样才能使你所选购的床垫质量和舒适度得到保证。床垫软硬度的选择对床垫的软硬度要求，中西方消费者有很大差异，消费者倾向于较硬的床垫，西方消费者则比较喜欢软的床垫。究竟床垫的软硬度何种为宜？这是消费者普遍关心的问题。科学证明，软床垫会降低脊骨承托，硬床垫的舒适度又不够，所以过硬过软的床垫对健康睡眠都不利。床垫的软硬度直接影响睡眠的质量，与偏硬的木板床垫和偏软的海绵床相比，软硬适中的弹簧床垫更有利于获得良好的睡眠。

到了冬季，大家挂在嘴边最多的话大概就是补水了吧？冬天天气干燥，容易流失水分，人的皮肤常常会显得很干燥，最为常见的就是嘴唇会干裂。所以，这时选择擦拭比较补水的护肤品来防止皮肤干燥就显得格外重要了。然而，除了皮肤会干燥之外，我们的皮沙发也会因为缺少水分而开裂，所以在冬季我们也应该加强对皮具沙发的水分补充。据了解，皮具沙发会干裂的原因是因为缺少护理或采用不好的清洁剂或多用水擦拭。若是用水清洗真皮，引入皮内的油脂在皮内纤维表面形成的油膜，就会与水发生水解作用，从而破坏皮革内部纤维之间的油膜，皮内油脂就会随水分的挥发而流失，因而皮革内部纤维之间就会相互粘结在一起，从而失去移动的回旋余地，结果皮革内部纤维之间的磨擦阻力就会变大，这就是真皮沙发开裂的根本原因。
