Abstract
Mechanical assemblies, particularly bearing assemblies, incorporate local sensing means for producing an electrical signal directly indicative of the movement of one part relative to another. The sensing means employs a toothed wheel or disc or a moulded magnetic plastics component which is designed to move, for example, rotate, with the one part and a sensor which is located to the other part. The sensor senses the motion of the toothed or moulded component and can utilize galvanomagnetic means, such as a Hall effect device, or a magnetoresistor, or a Wiegand effect device, to produce the aforesaid signal directly or after further processing.
Claims15
A compact bearing assembly, comprising:
- an inner bearing race;
- an outer bearing race;
- one of said inner and outer bearing races being rotatable about an axis while the other one of said inner and outer bearing races is stationary;
- means incorporated within said one of said inner and outer bearing races, as an integral part thereof, for producing a signal means;
- and
- means incorporated within said other one of said inner and outer bearing races, as an integral part thereof, for sensing said signal means, and therefore the movement of, said one of said inner and outer bearing races relative to said other one of said inner and outer bearing races.
