Engine/Bearing/772541-772569 ROLLER BEARING SPHERICAL

中文品名：球面滚子轴承

Series 22200K•1/12 Tapered Bore

系列22200K·1/12锥孔

In this design, two rows of rollers operate in separate raceways ground into the inner ring with a guide rib to guide the rollers.  The outer ring has a single spherical raceway, thus allowing the inner ring and rollers to freely compensate for angular errors due to inaccurate machine components or due to elastic deflection of the shaft or housing under loads.  As a result of the line contact, a large number of rollers, and the substantial contact angle, these bearings have large radial and thrust load capacity.  They are suitable for heavy shock and impact loads. This type of bearing must have an adapter sleeve when in use.

在这种设计中，两排滚子在单独的滚道上工作，磨入内圈，并有一个导向肋来引导滚子。外环具有单一的球形滚道，因此允许内环和滚子自由补偿由于机器部件不精确或由于轴或外壳在负载下的弹性变形而引起的角度误差。由于线接触、大量滚子和较大的接触角，这些轴承具有较大的径向和推力负荷能力。它们适用于重冲击和冲击载荷。这种类型的轴承在使用时必须有转接套。
