Angular ball bearings are commonly used whenever there is a demand to increase stiffness of bearing. The aforementioned can be achieved by obtaining proper preload in bearings. In common belief, has negative consequence: it increases the load rolling elements, which must lead lower durability bearing compared situation before use.

An interesting feature of dung beetle behaviour is that once they have formed a piece of dung into a ball, they roll it along a straight path away from the dung pile. This straight-line orientation ensures that the beetles depart along the most direct route, guaranteeing that they will not return to the intense competition (from other beetles) that occurs near the dung pile. Before rolling a ne...

Rolling bearings are considered to be rigid supports of a pinned nature. In fact, rolling develop displacements that depend on the external load and stiffness shaft which they supported. addition, tapered roller use preloading, has an additional effect in bearings. these affect internal deformations thus actual bearing. This paper presents methodology for determining loads bearings, taking into...

This paper presents a new approach to implementing agile design and manufacturing concepts. The approach is based on the integration of artificial intelligence (AI) and Internet technologies with the conventional design and manufacturing techniques. An architecture based on AI and Internet programming is proposed for remotely and quickly accessing bearing design and manufacturing expertise at l...

Leukocytes rolling on selectins extrude thin membrane tethers that might stabilize rolling velocities despite marked alterations in wall shear stress. To test this hypothesis, we used differential interference contrast videomicroscopy to visualize formation and breakage of membrane tethers as neutrophils rolled on P-selectin under flow. Neutrophils rapidly increased tether number as wall shear ...
