Locomotive Test Bench Gearbox Speed Reducers With Synchronizing Function Between Wheels

2s2000 Locomotive Test Bench Gearbox With Synchronizing Function Between Wheels

Description

2S2000 Gearbox is developed for a test bench to testing locomotive performance. It is designed of two speeds arrangement (stop and mechanical shifting), main input/ output being vertically offset. Via a pair of bevel gears, realize synchronizing function between wheels. Use oil-air cooler. Apply bearings and oil pump of foreign well-known brand.
