Custom Non-standard Locomotive Transfer Case | Technical Introduction

SAINEER custom locomotive transfer case is a heavy-duty power distribution gearbox independently developed for special railway locomotives, industrial shunting locomotives and off-standard rail transit equipment. Different from standardized universal gearboxes, this series adopts fully non-standard customized design, covering personalized customization of structural size, transmission ratio, output mode, load capacity and installation interface according to customers’ actual operating conditions and equipment parameters.

Built for harsh railway working conditions, the transfer case adopts high-strength cast steel housing and carburized alloy steel gear components. Precision grinding and heat treatment process endow the product with ultra-high shock resistance, fatigue resistance and heavy-load bearing capacity, which can stably cope with frequent start-stop, variable torque impact and continuous high-intensity operation of locomotives in mining yards, industrial parks and railway special lines.

In terms of technical performance, the custom transfer case features flexible power distribution logic, customizable input and output shaft specifications, multi-angle adjustable mounting brackets and optimized internal oil bath lubrication system. The integrated sealing structure effectively prevents dust, rainwater and lubricating oil leakage, ensuring stable and low-noise transmission in complex outdoor environments.

All non-standard products are designed and processed based on customer drawings, power requirements, installation space and operating environment. We support one-stop customized services including personalized transmission ratio calibration, shaft end structure improvement, overload protection configuration and appearance dimension optimization. Strict ISO production standards and full-process quality testing guarantee high matching degree, high compatibility and long service life of custom locomotive transfer cases, providing reliable customized power transmission solutions for global special railway locomotive equipment.
