The grinding jars of the mixer mill MM 500 vario perform radial oscillations in a horizontal position. The inertia of the grinding balls causes them to impact with high energy on the sample material at the rounded ends of the grinding jars and pulverize it.

The entire outside surface of the outer ring is assumed to be fixed in space with a center of O o (), which is the origin of a stationary coordinate system O o xyz.The axis of the outer ring or the bearing is on the O o y axis. The inner ring rotates with respect to its axis, which can be tilted, and the z axis is so chosen that such tilt/misalignment is only at the O o yz plane.

Strabismus is a visual disorder in which the eyes are misaligned and point in different directions. This misalignment may be constant or intermittent. When the eyes are misaligned, typically one eye will fixate on objects of interest while the other eye turns in (esotropia), out (exotropia), down (hypotropia), or up (hypertropia).

Misalignment. Misalignment is a common source of premature spalling. Misalignment occurs when an inner ring is seated against a shaft shoulder that is not square with the journal, or when a housing shoulder is out-of-square with the housing bore. Misalignment arises when two housings are not on the same center line.

Sand, ine metal from grinding or machining, and ine metal or carbides from gears wear or lap the rolling elements and races. In tapered bearings, the roller ends and inner ring rib wear to a greater degree than the races. This wear causes increased endplay or internal clearance, which can reduce fatigue life and create misalignment in the bearing.

Generally, the greater deformation is usually produced at the bearing near the impeller, causing axial misalignment. Misaligned ball or cylindrical roller bearings are characterized by axial vibration regardless of the balancing status. Vibration can appear at 1x, 2x, 3x RPM or at the number of bearing balls or rollers multiplied by the ...

Assume the fatigue life without misalignment as Lθ 0, and the fatigue life with misalignment as Lθ. The effect of the misalignment on the fatigue life can be found by calculating Lθ/Lθ=0. Figures 2 and 3 show the effect of misalignment on the life ratio for a deep groove ball and roller bearing, respectively.
