Abstract
A flexibility testing apparatus for wire or cable. Two circular, rotatable gears are mounted to a frame, one gear being a drive gear and the other being a driven gear. The driven gear is coplanar with the drive gear and the drive gear teeth are enmeshed with the driven gear teeth. Two rods are connected to the mounting holes of the drive gear and the wire or cable is attached to the rods using barrel end clamps for flexing. The driven gear can be rotated at different speeds by an electric motor or a pneumatic driving device.
Claims7
A flexibility testing apparatus for wire or cable comprising:
- a) a planar frame having a front major surface and a rear major surface;
- b) a circular, rotatable drive gear mounted to said frame and proximate said front major surface thereof, said drive gear having a first predetermined diameter and a first predetermined number of teeth disposed along a circumference thereof and a mounting hole spaced apart from a center thereof;
- c) a circular, rotatable driven gear mounted to said frame and proximate said front major surface thereof, said driven gear having said first predetermined diameter and said first predetermined number of teeth disposed along a circumference thereof and a mounting hole spaced apart from a center thereof, said driven gear being coplanar with said drive gear and said drive gear teeth being enmeshed with said driven gear teeth;
- d) a drive shaft connected to said center of said drive gear;
- e) means operatively connected to said drive shaft for initiating rotation thereof;
- and
- f) a moving/bending rod operatively connected to said mounting hole of each gear, said moving/bending rods each having means for mounting one end of a wire or cable thereto.
