AI Technical Summary
The existing technology lacks a means of dynamically detecting the meshing relationship between the rack wheel and the rack, resulting in the inability to timely and accurately detect position changes caused by installation errors, wear and roadbed settlement during actual operation, affecting the stability and safety of the rack vehicle.
An online detection device for rack wheels was designed, which includes a detection rack, a propulsion device, and a clamping device. The detection rack is consistent with the line rack. The propulsion device precisely moves the detection rack to engage with the rack wheel, and the clamping device provides preload force to achieve full-circle gear tooth detection. Actual operating conditions are simulated to obtain data such as meshing center distance, tooth surface contact area, and tooth profile error.
It realizes the direct detection of the actual meshing center distance between the rack wheel and the rack without moving the vehicle, improves the detection efficiency and accuracy, and ensures the smooth and safe operation of the rack vehicle.
