  • 圆锥滚子轴承 是可以承受大的轴向力的轴承（即，它们是良好的推力轴承）以及能够承受大的径向力。

内圈和外圈滚道是锥形部分，并且辊也制成锥形，使得如果投影，滚道和滚子轴线的锥形表面将在轴承的主轴线上的共同点处相遇。

使用这种锥形几何形状，因为它提供了一个更大的接触片，这允许承载比球形（球）轴承更大的载荷，而几何形状意味着每个滚子表面的切向速度与其滚道相同沿着接触片的整个长度，并且不发生差别洗涤。当滚筒滑动而不是滚动时，其可以在滚子到滚道界面处产生磨损，即，表面速度的差异产生擦洗动作。磨损将退化通常保持在轴承中的紧公差，并可能导致其他问题。在圆锥滚子轴承中可以实现更接近于纯滚动，并避免快速磨损。

滚子由内圈上的凸缘引导。这样可以使辊子由于动量而高速滑出。

这些锥体的半角越大轴承能承受的轴向力越大。

圆锥滚子轴承是可分离的，并具有以下组件：外圈，内圈和滚子组件（包含滚筒和保持架）。不可分离的内圈和辊组件称为锥体，外圈称为杯。在通过锥体相对于杯的轴向位置的安装期间建立内部间隙。

公制圆锥滚子轴承遵循ISO 355定义的指定系统。

历史

1898年，亨利获得专利[1] 用于圆锥滚子轴承。当时，圆锥滚子轴承是圣路易斯的运输制造商，并拥有三项马达弹簧专利。然而，他的专利是圆锥滚子轴承，使他的公司成功。

亨利在19世纪末是一个突破，因为轮轴使用的轴承自古以来没有太大变化。他们依赖于封闭在保持润滑剂的壳体中的轴承。这些被称为轴颈轴承，并且取决于润滑剂的功能。没有适当的润滑[2]，这些轴承由于摩擦导致的过热而失效。亨利能够通过使用实际轧制的锥形轴承的杯形和锥形设计来显着降低其轴承上的摩擦，通过分配重量来减少轴承上的载荷 并均匀地装载在杯子，锥体和轴承上。

应用

在许多应用中，圆锥滚子轴承用于背靠背对，从而可以在任一方向均匀地支撑轴向力。

一对圆锥滚子轴承用于汽车和车轮轴承，它们必须同时处理大的垂直（径向）和水平（轴向）力。圆锥滚子轴承的应用通常用于需要耐久性的中等速度，重型应用场合。常用的现实应用是农业，建筑和采矿设备，轴系，齿轮箱，发动机电机和减速机。

  • Tapered roller bearings are bearings that can take large axial forces (i.e., they are good thrust bearings) as well as being able to sustain large radial forces.

The inner and outer ring raceways are segments of cones and the rollers are also made with a taper so that the conical surfaces of the raceways and the roller axes if projected, would all meet at a common point on the main axis of the bearing.

This conical geometry is used as it gives a larger contact patch, which permits greater loads to be carried than with spherical (ball) bearings, while the geometry means that the tangential speeds of the surfaces of each of the rollers are the same as their raceways along the whole length of the contact patch and no differential scrubbing occurs. When a roller slides rather than rolls, it can generate wear at the roller-to-race interface, i.e. the differences in surface speeds creates a scrubbing action. Wear will degenerate the close tolerances normally held in the bearing and can lead to other problems. Much closer to pure rolling can be achieved in a tapered roller bearing and this avoids rapid wear.

The rollers are guided by a flange on the inner ring. This stops the rollers from sliding out at high speed due to their momentum.

The larger the half angles of these cones the larger the axial force that the bearing can sustain.

Tapered roller bearings are separable and have the following components: outer ring, inner ring, and roller assembly (containing the rollers and a cage). The non-separable inner ring and roller assembly is called the cone, and the outer ring is called the cup. Internal clearance is established during mounting by the axial position of the cone relative to the cup.

Metric tapered roller bearings follow the designation system defined by ISO 355.

History

In 1898, Henry was awarded a patent[1] for the tapered roller bearing. At the time, Taper roller bearing was a carriage-maker in St. Louis and held three patents for carriage springs. However, it was his patent for tapered roller bearings that allowed his company to become successful.

Henry were a breakthrough at the end of the 19th century because bearings used in wheel axles had not changed much since ancient times. They relied on bearings enclosed in a case that held lubricants. These were called journal bearings and depended on lubricants to function. Without proper lubrication[2], these bearings would fail due to excessive heat caused by friction. Henry was able to significantly reduce the friction on his bearings by using a cup and cone design incorporating tapered bearings which actually rolled, which reduced the load placed on the bearings by distributing the weight and load evenly across the cups, cones, and bearings.

Applications

In many applications tapered roller bearings are used in back-to-back pairs so that axial forces can be supported equally in either direction.

Pairs of tapered roller bearings are used in car and vehicle wheel bearings where they must cope simultaneously with large vertical (radial) and horizontal (axial) forces. Applications for tapered roller bearings are commonly used for moderate speed, heavy duty applications where durability is required. Common real world applications are in agriculture, construction and mining equipment, axle systems, gear box, engine motors and reducers.
