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
The present invention relates to a kind of transmission device used for optical cable repeated bending testing machine.
Background technology
Present optical cable back-and-forth bending test machine designs at outdoor optical cable, its course of work is roughly: get one section optical cable sample, optical cable is tightened at two ends by optical cable, the center section of optical cable is placed between a pair of equal-sized bending test wheel, an end of optical cable swings, the part that optical cable is between the two bending tests wheel will bend on the side face of bending test wheel, based on this course of work, present optical cable back-and-forth bending test machine comprises frame, be arranged on the motor of frame upper end, gearing and fork, gearing comprise the worm screw that is connected with drive of motor and with the worm gear of worm mesh, fork radially is fixedly installed on the worm gear along worm gear.The swinging end of fork is provided with a wire-clamping device, be fixed with the pair of curved experimental wheel on the frame of fork below, the frame of bending test wheel below is provided with a upright slide rail, and slidable fit has weight slide block on this slide rail, also is provided with a wire-clamping device on the weight slide block.When carrying out the optical cable crooked experiment, get one section optical cable sample, one end of optical cable is fixed on the wire-clamping device of swinging end of fork, the other end is clamped on the wire-clamping device of weight slide block, the interlude that makes optical cable is between two experimental wheels, and the distance between two experimental wheels adapts with the thickness of optical cable and be adjustable.Can realize the bending of optical cable on crooked experiment wheel side face by motor and the swing of actuator drives fork.The optical cable of bending test wheel top is swung with fork, and the optical cable of bending test wheel below drives weight slide block and slides up and down.
Performance requirement Apparatus for Bending at low-temp according to optical cable needs optical cable is carried out ± 90 ° of alternating bending tests, because the gearing of optical cable back-and-forth bending test machine is a worm gearing, so obtain to be fixed on the swing of the fork on the worm gear, just need motor to carry out the rotating campaign, therefore will control motor positive and inverse and pass through the swing of Worm and worm-wheel gearing driving pendulum rod with control section.And the thermal value of the thermal value of motor positive and negative alternate when rotating during far above unidirectional rotation, in identical environment temperature, temperature when the temperature the when motor of doing the rotating campaign reaches heating with the heat radiation balance will be higher than the motor of doing unidirectional rotary motion and reaches heating with the heat radiation balance, higher working temperature can influence motor properties.Be operated in for a long time under the higher temperature, the life-span of motor can be affected, and requires more or time requirement when longer at the rotating number of times, motor even can burn out.Simultaneously, motor positive and inverse need be controlled by control section, the price of control section is generally higher, less demanding but to the occasion that the rotating number of times is had relatively high expectations to the velocity uniformity of rotating, is unsuitable for coming the ground rotating of property performance period by the control section drive motor.
In addition, because outdoor optical cable comprises thicker steel wire and thicker and hard sheath, therefore present alternating bending equipment needs the big motor of driving power, but requires less to the number of bends of optical cable, according to the requirement of outdoor optical cable, the alternating bending number of times of each test is about 30 times.And inside cable is higher to the bending resistance performance demands, so according to different standard-requireds, inside cable ± 90 ° of alternating bending number of times are not wait to 1000 times for 100 times, so many rotating number of times can make motor burn because of thermal value is too high during test on existing testing equipment.
Summary of the invention
The purpose of this invention is to provide a kind of transmission device used for optical cable repeated bending testing machine, so that solve the problem that too much causes burn-down of electric motor in the prior art owing to the motor positive and inverse number of times.
For achieving the above object, the present invention adopts following technical scheme: a kind of transmission device used for optical cable repeated bending testing machine, this gearing comprises slider-crank mechanism, the slide block of slider-crank mechanism is the strip slide block, one side of strip slide block is provided with driving cog, band tooth slide block is meshed with a gear, forms rack and pinion drive mechanism, and described gear is used to drive the fork swing.
The crank of described slider-crank mechanism is the rotating disk that a rotation center is positioned at geometric center, and the pin joint of the connecting rod of this rotating disk and slider-crank mechanism is positioned on the card of rotating disk.
Gearing of the present invention comprises slider-crank mechanism, the slide block of slider-crank mechanism is provided with the driving cog that is meshed with gear, band tooth slide block and gear are formed rack and pinion drive mechanism, gear is used to drive the fork swing, the band tooth slide block driven wheel of slider-crank mechanism back and forth rotates, thereby the unidirectional rotary motion of crank is transformed crankmotion for gear, rotation repeatedly along with gear, fork output oscillating motion, can realize the swing of fork ± 90 ° by the length of adjusting crank, of the present invention simple in structure, motion is reliable, cost is low, the motion of fork is unrestricted, and angle of oscillation is bigger; This gear train is used for the optical cable back-and-forth bending test machine, and motor does not need rotating can obtain the swing of fork.
