Wheel drum and brake disk

Overview
Controlling vibration in a wheel bearing or disk brake by eliminating lobing and chatter in the machining process or trying to ensure a brake pad has the necessary friction qualities to function correctly are all simple tasks with the correct equipment.

Critical to the function of a rotating component are its shape and form, unwanted lobing or chatter on the flat area of a brake disk or on a wheel bearing will effect performance. The Taylor Hobson range of Talyronds can detect and help eliminate unwanted defects as detailed in the Talyrond links below.

Critical features on a brake pad are its ability to provide the necessary friction when brakes are applied, alternatively too much friction may be detrimental.
Taylor Hobson provide surface finish instruments to help predict the correct function of a component as detailed in the Form Talysurf links below.

Form Talysurf Inductive Systems
For accurate measurement of roughness, waviness and form.

Form Talysurf PGI Measurement Systems
Provides large gauge range/high resolution roughness,waviness and form measurement.

Talyrond 131 Range
Both Talyrond 130 and 131 systems provide high accuracy and repeatability with simple operation.

Wheel bearings, drums and brake components
Although a relatively simple component the brake disk has many features that require tight control. The disk faces should be parallel to one another and in turn parallel to the wheel face mount as well as having no extreme changes in thickness variation. Brake surfaces should also be flat and square to the axis of the disk's rotation to a specified tolerance.

As well as the flatness there should be no localised elements of lobing or chatter or thickness deviations in segmented areas of the disk surface that effect the overall brake function. All of the above can be controlled by combining Taylor Hobson’s Talyrond roundness measuring instruments with our Disk Brake Variation Software.
