PLC controlled foot pedal wear testing machine (three pairs)

PLC control foot pedal wear testing machine (three pairs) WDSD-8732

First, the machine is used to simulate the wear and tear of the pedal crank assembly of the bicycle when riding the bike after a certain mileage, the machine has been improved several times, the operation is simpler, the test is faster, can do three pairs of foot test at the same time, six feet count independently, do not interfere with each other, and the machine only stops the foot test and count after any foot is damaged. And retain the test results.

Second, the test principle: ISO4210-8:2014 4.3

Iii. Test method:

1) Select the appropriate shaft according to the screw size and fix it on the front and rear axes of the testing machine (pay attention to the positive and negative of a pair of foot installation);

2) Set the number of tests on the total counter according to the standard, and clear all counters;

3) Press the test key to start the test;

4) Check whether the assembly is flexible after the test is completed, and judge whether it is qualified according to the standard.

4. Technical parameters:

1) Cylinder: six sets, automatic lifting weight when loading

2) Load: 90 kg (including fixture, spring, hook and other total mass) can be adjusted to other weights

3) Adjustable load: wear resistance test of children's bicycle pedal can be carried out

4) Counter: 0--999,999 arbitrary setting (with power off hold function)

5) Counting accuracy: 100,000 times ±1 time

6) Rotation frequency: 0-120 times/MIN adjustable

7) Rotation accuracy: ≤±1 time/MIN

8) Micro switch: 6 sets (the specimen is damaged to automatically stop the foot rotation and counting, and retain the test results)

9) Unloading and loading: pneumatic automatic

10) Motor: AC frequency conversion control

11) Test workpieces: 3 pairs (6 pieces)

12) Power supply: 220V, 50Hz, 10A, 2KW, 5KPa

Five, the name of the main equipment:
