Matched bearings arranged in tandem

特点和优点

*高承载能力

根据设计，匹配轴承适用于重径向和轴向载荷。圆锥滚子轴承的轴向承载能力随接触角α的增加而增加。接触角的大小通常在10°和30°之间，与计算系数e（来自产品表）有关：e值越大，接触角越大。

*双向轴向载荷

根据设计，匹配轴承可以在特定轴向间隙或预紧力下在两个方向上轴向定位轴。

*高刚度

根据设计，匹配轴承可以提供相对刚性的轴承布置。

*成套交付

轴承和环形垫片在生产时是匹配的，成套交付，可随时安装。

*低摩擦

每个单个轴承滚道的投影线在轴承轴上的一个公共点相交，从而提供真正的滚动作用，因此在运行过程中摩擦力矩较低。

每个单个轴承的滚子端设计和法兰上的表面光洁度均经过优化，促进了润滑膜的形成，从而降低了摩擦。这还可以减少摩擦热和法兰磨损。此外，轴承可以更好地保持预紧力并在较低的噪音水平下运行。

*长使用寿命

与传统的直线滚道轮廓相比，基本设计轴承的冠状滚道轮廓和对数滚道轮廓轴承优化了沿接触表面的载荷分布，降低了滚子端的应力峰值，并降低了对错位和轴偏转的敏感性。

*增强的操作可靠性

滚子和滚道接触表面上优化的表面光洁度支持形成流体动力润滑膜。

*滚子轮廓和尺寸的一致性

圆锥滚子轴承的制造尺寸非常紧密

Features and benefits

*High load carrying capacity

Depending on the design, matched bearings are suitable for heavy radial and axial loads. The axial load carrying capacity of tapered roller bearings increases with increasing contact angle α. The size of the contact angle, which is usually between 10° and 30°, is related to the calculation factor e (from the product tables): the larger the value of e, the larger the contact angle.

*Axial loads in both directions

Depending on the design, matched bearings can locate the shaft axially in both directions with a specific axial clearance or preload.

*High stiffness

Depending on the design, matched bearings can provide a relatively stiff bearing arrangement.

*Delivered as a set

The bearings and ring spacer(s) are matched in production, are delivered as a set and are ready-to-mount.

*Low friction

The projection lines of the raceways of each single bearing meet at a common point on the bearing axis to provide a true rolling action and therefore low frictional moments during operation.

The optimized roller end design and surface finish on the flange of each single bearing promote lubricant film formation, resulting in lower friction. This also reduces frictional heat and flange wear. In addition, the bearings can better maintain preload and run at reduced noise levels.

*Long service life

The crowned raceway profiles of basic design bearings and the logarithmic raceway profiles bearings optimize the load distribution along the contact surfaces, reduce stress peaks at the roller ends, and reduce the sensitivity to misalignment and shaft deflection compared with conventional straight raceway profiles.

*Enhanced operational reliability

Optimized surface finish on the contact surfaces of the rollers and raceways supports the formation of a hydrodynamic lubricant film.

*Consistency of roller profiles and sizes

Tapered roller bearings are manufactured to such close dimension
