TDO型双线尺寸锥形辊轴承

TDO Type double row inch size tapered roller bearings are a common type of tapered roller bearings. It has a one-piece (double) outer ring and two single inner rings. TDO Type double row inch tapered roller bearings are usually supplied with an inner-ring spacer as a pre-set assembly. This configuration gives a wide practical bearing spread and is frequently chosen for applications where overturning moments are a significant load component. TDO bearings can be used in fixed (locating) positions or allowed to float in the housing bore, for example, to compensate for shaft expansion. TDO CD outer rings also are available in most sizes. These outer rings have holes in the O.D. that permit the use of pins to prevent external ring rotation in the housing.

Features of TDO Type double row tapered roller bearings

• 高负载能力
  TDO Type Double row tapered roller 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 contact angle size, 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
  TDO Type Double row tapered roller bearings locate the shaft in both directions with a specific axial clearance or preload.
• 高刚度
  TDO Type Double row tapered roller bearings provide a stiff bearing arrangement.
• 低摩擦
  法兰的优化辊端设计和表面饰面可促进润滑剂膜的形成，从而降低摩擦。这也减少了摩擦热和法兰磨损。此外，轴承可以更好地维持预紧力，并以降低的噪声水平运行。
• 长期使用寿命
  基本设计轴承和对数跑道轮廓的冠冕跑道曲线优化了沿着接触表面的负载分布，减少滚子端处的应力峰，并降低对未对准和轴偏转的敏感性，与常规的直跑道配置文件相比。
• Enhanced operational reliability
  The optimized surface finish on the contact surfaces of the rollers and raceways supports the formation of a hydrodynamic lubricant film.
• 滚子曲线和尺寸的一致性
  The rollers incorporated in our TDO Type double row tapered roller bearings are manufactured to such close dimensional and geometrical tolerances that they are practically identical. This provides optimal load distribution, reduces noise and vibration, and enables preload to be set more accurately.
