[0003] The one-way clutch is mainly divided into roller type one-way clutch and wedge type one-way clutch. The roller type one-way clutch mainly utilizes a circle of rollers. When the one-way clutch rotates, the rollers are stuck between the inner wall of the inner chamber of the outer ring at the bottom of the transmission shaft and the outer wall of the top of the driving gear shaft. The friction force is used to lock the one-way clutch, thereby enabling the transmission shaft to drive the driving wheel shaft to rotate and realize transmission.

At the same time, the lower teeth of the driving gear shaft of the existing one-way device need to have higher accuracy because they need to transmit power, and they also need to be tested.

[0024] Furthermore, a vertical guide rod is fixed to the top surface of the lifting plate 22 , and the vertical guide rod is inserted into a corresponding vertical guide through hole on the top plate of the upper support frame 20 .
[0025] Furthermore, a central vertical through hole is formed in the middle of the transmission shaft 23, a vertical column 26 is fixed in the middle of the bottom surface of the lifting plate 22, the vertical column 26 is inserted in the central vertical through hole, a groove 261 is formed on one side wall of the bottom end of the vertical column 26, a raised limiter 231 is formed on the lower inner side wall of the central vertical through hole of the transmission shaft 23, the raised limiter 231 is inserted in the groove 261, a rotary pressure sensor 1 is fixed on one side wall of the groove 261, and the sensing end of the rotary pressure sensor 1 is pressed against the corresponding side wall of the raised limiter 231. The electrical connection line of the rotary pressure sensor 1 can extend upward along the vertical through hole formed in the middle of the vertical column 26 and extend out of the through hole formed on the lifting plate 22 to be electrically connected to the external control host, which is a conventional structure and will not be described in detail here.
[0026] Furthermore, a self-lubricating pad 2 is fixed to the middle of the top surface of the horizontal fixing plate 11 , and the bottom surface of the driving gear shaft 101 of the isolator 100 is pressed against the top surface of the self-lubricating pad 2 .
[0027] Furthermore, the top surfaces of the bottom fixing plates 10 at the left, right, front and rear sides of the horizontal fixing plates 11 are all fixed with side support frames 30, and the adjusting screws 31 are screwed into the middle transverse screw-connecting through holes of the vertical plates of the side support frames 30, and the outer ends of the adjusting screws 31 extend out of the outer side walls of the vertical plates of the side support frames 30 and are formed with rotating parts, and the inner ends of the adjusting screws 31 extend out of the inner side walls of the corresponding vertical plates of the side support frames 30 and are movably connected with arc-shaped clamping plates 32.

When it is inserted into the top of the upper shaft 102, the upper shaft 102 needs to be rotated to ensure that the spline protrusion matches the spline groove. Since six spline protrusions are formed on the outer wall of the bottom end of the transmission shaft 23, there are also six corresponding spline grooves, and the small number makes it easy to align.
[0035] Then, the bottom end of the transmission shaft 23 is inserted into the top of the upper shaft 102, and the spline protrusion is inserted into the corresponding spline groove to achieve installation;
[0036] Then, by driving the motor 25, the transmission shaft 23 is driven to rotate, so that the raised limit portion 231 generates pressure on the sensing end of the rotary pressure sensor 1, and transmits its sensing signal to the control host. The detected value is displayed on the display screen electrically connected to the control host, and its limit value can be measured. The detection is convenient and the clamping effect is good.
