Belt test apparatus
View Patent ↗A flexible member test apparatus comprising a driver member having a first diameter and a second diameter, the first diameter is not equal to the second diameter, a first driven member coupled by a first flexible member to the driver member through contact of the first flexible member with a first diameter surface, a second driven member coupled by a second flexible member to the driver member through contact of the second flexible member with a second diameter surface, the first driven member rotationally coupled to a magnetic particle clutch, and the second driven member rotationally coupled to the magnetic particle clutch.
1. A flexible member test apparatus comprising:
a driver member having a first diameter and a second diameter, the first diameter is not equal to the second diameter;
a first driven member coupled by a first flexible member to the driver member through contact of the first flexible member with a first diameter surface;
a second driven member coupled by a second flexible member to the driver member through contact of the second flexible member with a second diameter surface;
the first driven member rotationally coupled to a magnetic particle clutch; and
the second driven member rotationally coupled to the magnetic particle clutch.
2. The flexible member test apparatus as in claim 1 , wherein the first diameter is approximately 0.98 times the second diameter.
3. The flexible member test apparatus as in claim 1 , wherein the first driven member and the second driven member are coaxial.
4. The flexible member test apparatus as in claim 1 , wherein the magnetic particle clutch torque is proportional to an input current and is independent of a slip RPM.
5. A flexible member test apparatus comprising:
a driver member;
a first driven member coupled by a first flexible member to the driver member;
a second driven member coupled by a second flexible member to the driver member;
the first driven member rotationally coupled to a magnetic particle clutch first input shaft;
the second driven member rotationally coupled to a magnetic particle clutch second input shaft; and
the magnetic particle clutch first input shaft rotated at a speed different than a rotation speed for the magnetic particle clutch second input shaft.
6. The flexible drive member test apparatus as in claim 5 , wherein the first flexible member is driven as a speed not equal to the speed of the second flexible member.
7. A flexible member test apparatus comprising:
a driver member;
a first driven member coupled by a first flexible member to the driver member;
a second driven member coupled by a second flexible member to the driver member;
the first driven member rotationally coupled to a slip clutch first input shaft;
the second driven member rotationally coupled to a slip clutch second input shaft; and
a first pulley entrained with the first flexible member having a diameter different from a second pulley entrained with the second flexible member wherein the slip clutch first input shaft rotates at a speed different than a rotation speed for the slip clutch second input shaft.
8. The flexible member test apparatus as in claim 7 , wherein the first pulley diameter is approximately 0.98 times the second pulley diameter.
9. The flexible member test apparatus as in claim 7 , wherein the first driven member and the second driven member are coaxial.
10. The flexible member test apparatus as in claim 7 , wherein the slip clutch torque is proportional to an input current and is independent of a slip RPM.
