Wheel alignment, which is sometimes referred to as breaking or tracking, is part of standard automobile maintenance that consists of adjusting the angles of wheels to the car manufacturer specifications. [1] The purpose of these adjustments is to reduce tire wear and to ensure that vehicle travel is straight and true (without "pulling" to one ...
[1] [2] When the equipment is down, production requiring the equipment may be delayed. Bearings or mechanical seals may be damaged and need to be replaced. Shaft alignment is the process of aligning two or more shafts with each other to within a tolerated margin. The process is used for machinery before the machinery is put in service.
A ball bearing. A bearing is a machine element that constrains relative motion to only the desired motion and reduces friction between moving parts.The design of the bearing may, for example, provide for free linear movement of the moving part or for free rotation around a fixed axis; or, it may prevent a motion by controlling the vectors of normal forces that bear on the moving parts.
Double-row angular contact ball bearings have a steep mounting, which also can bear tilting effects. Other advantages of double-row bearings are their rigidity and compactness. Their disadvantage is they need better alignment than single-row bearings. Flanged Bearings with a flange on the outer ring simplify axial location.
The Bears are trying to find where their offensive linemen fit best, which included a shake up at left and right tackle at minicamp Tuesday. Bears experimenting with offensive line alignment in ...
The mechanical belt drive, using a pulley machine, was first mentioned in the text of the Dictionary of Local Expressions by the Han Dynasty philosopher, poet, and politician Yang Xiong (53–18 BC) in 15 BC, used for a quilling machine that wound silk fibres onto bobbins for weavers' shuttles. [1]
A simple approximation to perfect Ackermann steering geometry may be generated by moving the steering pivot points [clarification needed] inward so as to lie on a line drawn between the steering kingpins, which is the pivot point, and the centre of the rear axle. [2]
Reduction drive (also with a transformation of the direction of rotation) A reduction drive is a mechanical device to shift rotational speed. A planetary reduction drive is a small scale version using ball bearings in an epicyclic arrangement instead of toothed gears.
