UConn in-house Gearbox Dataset

A two‑stage spur‑gear reducer was instrumented in the Dynamic Systems & Control Laboratory at the University of Connecticut.
• Stage 1: 32‑tooth pinion ↔ 80‑tooth gear
• Stage 2: 48‑tooth pinion ↔ 64‑tooth gear
A 3‑axis PCB accelerometer was mounted on the housing; signals were sampled at 20 kHz through a dSPACE DS1006 board while the shaft ran under constant torque supplied by an adjustable magnetic brake. Shaft speed was logged with a tachometer and used to perform Time‑Synchronous Averaging (TSA) so every record starts at the same angular position, eliminating speed wander.
File structure
UConn_Gearbox.csv is a plain UTF‑8 CSV with:
• 3600 rows – vibration samples per record (≈ 0.18 s at 20 kHz)
• 936 columns – individual TSA‑aligned records
• columns 1‑104 → class H
• columns 105‑208 → class MT
• columns 209‑312 → class RC
• columns 313‑416 → class SP
• columns 417‑520 → class CH5
• columns 521‑624 → class CH4
• columns 625‑728 → class CH3
• columns 729‑832 → class CH2
• columns 833‑936 → class CH1

Thus each class contains 104 records, giving 936 records × 3600 points in total.
