Abstract
Official abstract text for this publication.
A belt drive monitoring system comprising a driver, a driven, the driver and driven connected by an endless member, a first magnetic member having a magnetic field attached to the driver, a second magnetic member having a magnetic field attached to the driven, a first sensor disposed to detect a changing magnetic field caused by passage of the first magnetic member, a second sensor disposed to detect a changing magnetic field caused by passage of the second magnetic member, a first transmitter configured to wirelessly transmit to a receiver a first data signal from the first sensor and a second transmitter configured to wirelessly transmit to the receiver a second data signal from the second sensor, and the receiver configured to manipulate the data signal whereby a system parameter is calculated and provided to a user.
First claim
Opening claim text (preview).
We claim: 1. A belt drive monitoring system comprising: a driver; a driven; the driver and driven connected by an endless member; a first plurality of magnetic members having a magnetic field attached to the driver at a first radius from an axis of rotation of the driver with a first predetermined spacing; a second plurality of magnetic members having a magnetic field attached to the driven at a second radius from an axis of rotation of the driven with a second predetermined spacing; a first sensor disposed to detect a changing magnetic field caused by passage of the first plurality of magnetic members; a second sensor disposed to detect a changing magnetic field caused by passage of the second plurality of magnetic members; a first transmitter configured to wirelessly transmit to a receiver a first data signal from the first sensor and a second transmitter configured to wirelessly transmit to the receiver a second data signal from the second sensor; and the receiver configured to manipulate the first date signal and the second data signal whereby a system parameter is calculated and provided to a user. 2. The belt drive monitoring system as in claim 1 , wherein the endless member comprises a belt. 3. The belt drive monitoring system as in claim 1 , wherein the first sensor and the second sensor each comprise a Hall effect sensor. 4. The belt drive monitoring system as in claim 1 further comprising: a third sensor disposed to detect a changing magnetic field caused by passage of the first plurality of magnetic members; and a fourth sensor disposed to detect a changing magnetic field caused by passage of the second plurality of magnetic members. 5. The belt drive monitoring system as in claim 4 , wherein the third sensor and the fourth sensor each comprise a Hall effect sensor. 6. The belt drive monitoring system as in claim 5 , wherein the first transmitter is configured to wirelessly transmit to the receiver a third data signal from the third sensor and the second transmitter is configured to wirelessly transmit to the receiver a fourth data signal from the fourth sensor. 7. The belt drive monitoring system as in claim 1 , wherein the system parameter comprises one of a speed difference, a slip percentage or a drive efficiency. 8. The belt drive monitoring system as in claim 6 , wherein the system parameter comprises one of a speed difference, a slip percentage or a drive efficiency.
