Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model embodiment；
Fig. 2 is the exploded view of Fig. 1.
Specific embodiment
The utility model is described in further detail below in conjunction with figure embodiment.
As shown in Figure 1, 2, a kind of axis through type tension sensor, including elastomer 1, bearing 2, left end cap 3,4 and of right end cap
Stop screw 5, bearing 2 are self-aligning ball bearing, and elastomer 1 is bending girder construction, and the middle part of elastomer 1 is axially offered for bearing
The bearing hole 11 of 2 installations, bearing 2 are mounted on the middle position of bearing hole 11, are respectively provided on the left and right outer ring of bearing 2 anti-
The only circlip 7 that bearing 1 moves axially, circumferential on the inner wall of bearing hole 11 to form the annular being embedded in for circlip 7 recessed
Slot 111, the toroidal cavity 12 coaxial with bearing hole 11 is formed on elastomer 1, and the middle circle of 12 inside of toroidal cavity is formed
The deformation region 13 of elastomer 1, deformation region 13 are linked together by the elastomer of crossbeam 13a and outside, when roller passes through
After bearing 2, the power that roller can be rotated together with bearing 2, while be will act on roller is transmitted to the shape of elastomer 1 by bearing
Become on region 13, output signal；Stop screw 5 is 4, is radially offered on the outer circumference surface of elastomer 1 for stop screw 5
The threaded hole 14 of installation, stop screw 4 pass through in threaded hole 14 to toroidal cavity 12, the inner end of stop screw 5 and deformation region
Gap between 13 is to limit distance A, when 1 normal stress deformation of elastomer, stop screw 4 and 1 deformation region of elastomer
13 there are gaps, and when sensor overload, the inner end of stop screw 5 offsets with the deformation region 13 of elastomer 1, causes elastomer
1 no longer deformation, plays the role of overload protection；Limit distance A between the inner end and deformation region 13 of stop screw 5 can basis
The range of sensor settings is adjusted；Left end cap 3 and right end cap 4 are separately positioned on the left and right sides of elastomer 1, left end cap 3
With several counterbores 31 and 41 are offered on right end cap 4, the left and right sides of elastomer 1 offers corresponding mounting hole 16, passes through ten

The effect of position；Conducting wire line outlet is offered in the side of elastomer 1, corresponds to the position of conducting wire line outlet in the outside of elastomer 1
It sets and aviation socket 15 is installed, fast and easy plug uses, and signal is drawn, and can effectively seal by conducting wire, does not influence to carry
The transmitting of lotus.
Specific installation process are as follows: bearing 2 is pressed into 11 position of bearing hole at 1 center of elastomer, then by 2 circlips
In 7 two annular grooves 111 with Circlip tongs insertion elastomer 3, for preventing the axial movement of bearing 2；Again with 4 cross recesses
Left end cap 3 and right end cap 4 are fixed on the left and right sides of elastomer 3 by countersunk head screw 6；To it is above-mentioned after the installation is completed, by 4 limit
Screw 5 is screwed on 1 periphery of elastomer corresponding 14 position of threaded hole.
Working principle is such that be transmitted on elastomer 1 when the active force of roll shaft by bearing 1, makes among elastomer 1
13 stress of annulus, that is, deformation region is curved under deformation occurs, with the limit distance A between the stop screw 7 that is fixed on elastomer 1
Become smaller.If active force continues to increase, 1 middle circle of elastomer (i.e. deformation region 13) is finally contacted with stop screw 5, to reach
To the purpose of overload protection.
Limit distance A can be adjusted according to specified range, such as play limited screw 5 in 120% specified range
Protective effect, as long as being loaded onto the 120% of specified range to sensor when calibration, 1 middle circle (i.e. deformation region of elastomer
13) deflection increases, with screwdriver rotary stopper screw 5, until twisting motionless.
The utility model is specifically described below by design principle and technical concept.
1) design principle schematic diagram:
As shown in Figure 1,4 stop screws 5 are mounted on the periphery of elastomer 1, when 2 stress of bearing, elastomer 1 is bent
Deformation, the distance between stop screw 5 become smaller, until contact, to protect elastomer 1 due to overload causes plastic deformation
Damage.
2) sensor whole design:
Sensor is mainly by elastomer 1, left and right end cap 3 and 4, bearing 2, and stop screw 5 etc. is formed.In view of sensing
Device easily causes to scrap due to the unreasonable of limit distance A because of overload in use, and position limiting structure is designed to limit
Distance A is adjustable.Simultaneously in actual use since sensor is often subject to opposition, to avoid sensor because reversed
It overloads and causes to scrap, reverse overload protection structure is devised on elastomer 1, in addition to rotate convenient for roll shaft, in elastomer 1
Centre installation self-aligning ball bearing 2.
The advantages that from structure, the present embodiment has structure simple, compact, and in-site installation is convenient, relatively reliable；From skill
It is said in art, the present embodiment is the good combination body of stop screw and sensor, does not change original axis through type tension sensor and surveys
The form of power.From practicability, the present embodiment provides great convenience in terms of installation and maintenance for client.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without deviating from the technical principle of the utility model, several improvements and modifications can also be made, these change
