Test Principle
The device rotates the bicycle bottom bracket via a motor while applying a constant load using weights or a force application system. The PLC controls rotational speed and cycle count in closed-loop, automatically stopping when the preset number of cycles is reached or when the bottom bracket fails. This setup ensures repeatable, safe, and accurate abrasion testing.
Operation Instructions
(1) Mount the bottom bracket securely in the test fixture.
(2) Connect the main power and start the PLC touchscreen interface.
(3) Set test parameters: load, rotational speed, and number of cycles.
(4) Start the test; the device rotates the bottom bracket and applies load automatically.
(5) Monitor rotational speed and cycle count in real time.
(6) The system automatically stops when the preset cycles are reached or the specimen fails.
(7) Periodically check the machine, fixtures, and motor; maintain lubrication and cleanliness.
Test Procedures
(1) Install the bottom bracket in the fixture and secure it.
(2) Set test parameters: load weight, rotational speed, and number of cycles.
(3) Start the rotational abrasion test; the system automatically tracks cycle count.
(4) The machine automatically stops when the set cycles are reached or specimen failure occurs.
(5) Inspect the bottom bracket for wear, deformation, or damage.
(6) Record the test data and compile the test report.
Maintenance Information
(1) Regularly inspect fixtures, weights, and motor for wear or damage.
(2) Keep all moving parts lubricated and free of debris.
(3) Verify calibration of rotational speed and load sensors periodically.
(4) Ensure the PLC control system is updated and functioning properly.
