Transmission device used for optical cable repeated bending testing machine

Abstract

The invention relates to a transmission device used for an optical cable repeated bending testing machine, comprising a crank sliding block mechanism; the sliding block of the crank sliding block mechanism is a strip-shaped sliding block, one side surface of which is provided with transmission teeth; a sliding block with teeth is meshed with a gear so as to form a gear rack transmission mechanism;and the gear is used for driving a swinging rod to swing. The sliding block of the crank sliding block mechanism is provided with transmission teeth meshed with the gear; the sliding block with teethand the gear form the gear rack transmission mechanism; the gear is used for driving the swinging rod thereon to swing; the sliding block with teeth of the crank sliding block mechanism drives the gear to rotate in a reciprocating manner so as to change the unidirectional rotating movement of the crank into reciprocating rotating movement of the gear; with the reciprocating rotation of the gear,the swinging rod outputs swinging movement and can realize swinging by plus or minus 90 degrees by adjusting the length of the crank. The transmission device has simple structure, reliable movement, low cost, no limitation for movement of the swinging rod and larger swinging angle.

Description

technical field [0001] The invention relates to a transmission device for an optical cable repeated bending test machine. Background technique [0002] The current optical cable repeated bending test machine is designed for outdoor optical cables. Its working process is roughly as follows: take a section of optical cable sample, tighten the optical cable through both ends of the optical cable, and place the middle part of the optical cable in a pair of equal-sized bending testers. Between the wheels, swing one end of the optical cable left and right, and the part of the optical cable between the two bending test wheels will bend on the peripheral surface of the bending test wheel. Based on this working process, the current optical cable repeated bending test machine includes frame, A motor, a transmission device and a pendulum rod are arranged on the upper end of the frame. The transmission device includes a worm connected to the motor and a worm gear meshed with the worm ge...
