Akron abrasion testing machine, Abrasion testing machine Product features
1. Structure diagram:
2. Transmission mechanism: the motor is connected with the reducer through the coupling shaft to make the rubber wheel shaft rotate clockwise, and the sample is clamped on the rubber shaft by the sample.
3 loading mechanism: the grinding wheel bracket is connected with the grinding wheel bracket through the supporting shaft and bearing. The grinding wheel bracket can swing flexibly. The grinding wheel is installed on the grinding wheel bracket through the grinding wheel shaft, and the bearing is installed inside. The counterweight is used to balance the weight of the pressure arm and adjust the grinding wheel to the vertical position. A weight attached to a bracket. Under the action of lever, the actual pressure acting on the rubber wheel is 26.7n. The brush on the grinding wheel bracket is used to remove the rubber chips attached to the grinding wheel.
Grinding wheel specification: the abrasive is alumina, the particle size is 36, the bonding agent is clay, the hardness is medium hard 2, and the size is 150 × 32 × 25 mm.
4. Angle adjusting mechanism: the motor base is connected with the angle adjusting bracket through the shaft, the shaft is equipped with a pointer, the angle plate is installed on the side of the angle frame, the angle between the angle adjusting knob and the grinding wheel shaft is rotated, and then the locking nut is used for locking.

3.5 electronic counting device: this device is a pre-determined control counter. After "starting", the internal executive relay will pull in immediately, and its contact will be directly connected with the power supply to output to the outside of the machine to make the motor run. The shaft end of the grinding wheel shaft is equipped with a photoelectric conversion switch, which is connected with the counter for counting. When the counting reaches the preset value, the relay will automatically disconnect, and the buzzer will send out sound signals When the power is lost, the data is saved for nearly 10 years. Principle block diagram of control counter.

? Akron abrasion testing machine, Abrasion testing machine Sample standard
The samples shall meet the requirements of GB / t1689 "determination of abrasion resistance of vulcanized rubber (with Akron Abrader)".
1. The sample is strip-shaped, the length is (D + H) π + 0 ~ 5mm, the width is 12.7 ± 0.2mm, and the thickness is 3.2 ± 0.2mm. Its surface should be flat without cracks, impurities, etc.
2. The two sides of the sample are bonded to the rubber wheel after grinding, but there should be no tension during bonding.
3. The diameter of the rubber wheel is 68mm, the thickness is 12.7 ± 0.2mm, the hardness is 75 ~ 80 degrees (shore a type), and the diameter of the center hole should conform to the diameter of the rubber wheel shaft.

Akron abrasion testing machine, Abrasion testing machine usage method
1. The testing machine should be placed stably.
2. Plug the motor plug, power cord plug and photoelectric conversion switch plug into the corresponding socket on the back panel of the electronic counter.
3. Loosen the lock nut, rotate the angle adjustment knob to make the pointer point at the required inclination angle (generally 15 °), and then tighten the lock nut.
4. Fix the rubber wheel bonded with the sample on the rubber wheel shaft, place the weight on the grinding wheel bracket, turn on the power supply of the electronic counter, turn on the power switch, adjust the preset number button to 600 rpm (the intermediate value of the pre grinding time of 15-20 min), press the "run" button to start the pre grinding. When the counting reaches the preset value, press the "stop" button and the "zero" button to remove the rubber wheel and use the balance The weight is accurate to 0.001g.
5. Fix the pre ground rubber wheel on the rubber wheel shaft, adjust the preset number key to 3416 RPM (1.61km test mileage), and then conduct the test. After the test, take down the sample. Brush off the crumbs and weigh to 0.001g within 1 hour.
6. Change the sample to continue the wear test.
7. The wear volume and wear index of the sample shall be calculated according to the provisions of GB 1689.

Akron abrasion testing machine, Abrasion testing machine Installation steps and maintenance
1. Check whether the transmission parts rotate normally before use. When the weight is not installed (but the weight shaft and retaining ring must be placed on the grinding wheel bracket), the grinding wheel should be in the vertical position.
2. Adjust the testing machine base to horizontal state before calibration.
3. The force of rubber tire measured by weight or corresponding force measuring device should be 26.7n.
4. Adjust the angle adjusting bolt, and measure the angle between the rubber wheel shaft and the grinding wheel shaft with the angle measuring instrument of Akron abrasion machine, which is generally 15 degrees
