Transmission belt 6 bypasses the lower summit 11 of directive wheel 1, the upper summit 21 of tensioning wheel 2, the lower summit of tensioning wheel 2 successively
22nd, on the upper summit 41 of lower directive wheel 4, motor output pulley 5 and train part belt wheel 7；
Tensioning wheel 2, which is arranged on, is used to providing the tie unit 3 of tensile force, the direction of tensile force and first level line and the
Two horizontal lines are parallel to each other.
Specifically, as shown in figure 1, train part belt wheel 7 be located at the top, be fixed on the installation flat board with vibration isolation, drive
Dynamic motor output pulley 5 is located at bottom, and upper directive wheel 1, tensioning wheel 2, tie unit 3 and lower directive wheel 4 are located at motor
Between output pulley 5 and train part belt wheel 7, and positioned at the right side of motor output pulley 5 and train part belt wheel 7.
Further, motor output pulley 5 is centrally located on same vertical curve with train part belt wheel 7, or
At least the axially and radially misalignment of train part belt wheel 7 and motor output pulley 5 is controlled within 1 degree.On lead
It is centrally located to wheel 1 and lower directive wheel 4 on same vertical curve, tensioning wheel 2 is located at the right side of upper directive wheel 1 and lower directive wheel 4.
Transmission belt 6 bypass successively the lower summit 11 of directive wheel 1, the upper summit 21 of tensioning wheel 2, the right half cycle of tensioning wheel 2,
The lower summit 22 of tensioning wheel 2, the upper summit 41 of lower directive wheel 4, then further around the lower half for motor output pulley 5 of overdriving, most
The upper half of train part belt wheel 7 is bypassed afterwards, the lower summit 11 of directive wheel 1 is returned, and forms the driving-chain of a closing.
Motor driving motor output pulley 5 is rotated, and motor output pulley 5 drives transmission belt 6 to rotate, and passes
Dynamic band 6 drives train part belt wheel 7 to rotate.The power of motor is passed to by train part belt wheel 7 by transmission belt 6.
And upper directive wheel 1, tensioning wheel 2, the effect of tie unit 3 and lower directive wheel 4 are to measure and control transmission belt 6
Tensile force.
In the present embodiment, because tie unit 3 applies pulling force F in the horizontal direction, and transmission belt 6 to tensioning wheel 2
In in the horizontal direction on the upper summit 21 of tensioning wheel 2 and lower summit 22, therefore the tensile force T acted on tensioning wheel 2 is also along water
Square to.
Specifically, as shown in Figure 1-2, during measurement, tie unit 3 pulls to the right tensioning wheel 2, and tie unit 3 is to tensioning wheel 2
Apply pulling force F, tensioning wheel 2 pulls transmission belt 6, while the also tensile force T of driven band 6.Due to the upper summit 21 of tensioning wheel 2
There is transmission belt 6 in the horizontal direction with lower summit 22, transmission belt 6 applies two tensile force T, therefore F=2T to tensioning wheel 2.
So, by measuring pulling force F size, the size for obtaining tensile force T can be calculated；Equally, by controlling pulling force F
Size, can accurately control tensile force T size.
Further, as shown in figure 3, tie unit 3 includes force snesor 3-5 and telescopic component 3-6, telescopic component 3-6
Tensioning wheel 2 is pulled in the horizontal direction, and force snesor 3-5 is used for the pulling force F for measuring telescopic component 3-6.
Specifically, after electric power starting, belt stretcher initialization, host computer and tie unit 3 set up communication connection.
User inputs the desired value of tensile force, and desired value is multiplied by the desired value as force snesor 3-5, skin after 2 by belt stretcher
The pulling force of force snesor 3-5 measurements is adjusted by adjusting telescopic component 3-6 displacement with tensioning apparatus, and passes through PID control
Carry out force sensor 3-5 and measure the accurate control of pulling force, and then realize tensile force T accurate control.
Further, as shown in figure 3, tie unit 3 also includes axle 3-1, tapered sleeve 3-2, air bearing 3-3 and support 3-4；
Axle 3-1 one end passes through tensioning wheel 2, and is fixedly connected by tapered sleeve 3-2 with tensioning wheel 2, and the axle 3-2 other end leads to
The side that air bearing 3-3 is crossed with support 3-4 is connected, and support 3-4 opposite side passes through force snesor 3-5 and telescopic component 3-6
Connection.
Specifically, tensioning wheel 2 is fixed on axle 3-1 by tapered sleeve 3-2, air bearing 3-3 is bolted on
On support 3-4, the telescopic component 3- of tension adjusting is connected to respectively for measuring the force snesor 3-5 two ends of tensile force
6 and support 3-4.
During measurement, telescopic component 3-6 drives force snesor 3-5 movements, and force snesor 3-5 drives support 3-4 movements, support
3-4 band moving axis 3-1 movements, axle 3-1 finally drives tensioning wheel 2 to move.Force snesor 3-5 is also measured while pulling force F is transmitted
Pulling force F size.
Compared with prior art, the invention has the advantages that：
1) tensile force is accurately controlled
Ensure that the tensile force T of transmission belt and the pulling force F of force snesor are parallel to each other by upper directive wheel and lower directive wheel.
Ensure that the pulling force F of force snesor is equal to 2 times of tensile force with this.By the pulling force for accurately measuring and controlling force snesor
Realize the accurate measurement and control of tensile force.
2) vibration and noise are small
Easily there is belt tension in transmission belt running unstable, cause drive belt slip, so produce vibration and
Noise problem, belt stretcher of the invention can automatically adjust and control belt tension, reduce vibration and noise is asked
The generation of topic.
3) signal to noise ratio is high
Tensioning wheel reduces the running noises of tensioning wheel using non-contact air bearing, further increases train part
Carry out signal to noise ratio when vibration and noise testing.
Above-described is only the principle and preferred embodiment of the present invention.It should be pointed out that for the common skill of this area
For art personnel, on the basis of the principle of the invention, some other modifications can also be made, the protection model of the present invention is also should be regarded as
Enclose.
