Forged Steel Railway Driven Gear

Product Introduction:

The driven gear, a key component of the running system of railway vehicles, mainly undertakes the functions of transmitting power, supporting the vehicle body, guiding, and braking. As the "walking cornerstone" of railway transportation, its performance directly affects the safety and efficiency of trains. With the advancement of intelligent and lightweight technologies, the driven wheel is evolving from a traditional mechanical component to a high-end equipment featuring "intelligent perception + precise operation and maintenance", providing core support for the high-quality development of the railway industry.

FAQ：

Q1: What material is this railway driven wheel forged from?

Our railway driven wheels are forged from high-strength alloy steel, mainly using grades such as 17CrNiMo6-4/18CrNiMo7-6/20CrMnMo or other customized heat-treated steel. The forging process ensures high density, excellent wear resistance, fatigue resistance and mechanical performance, meeting international railway standards.

Q2: Can you provide customized sizes and drawings for the driven wheel?

Yes, we support customized forging based on your 2D/3D drawings or technical parameters.

Customization includes outer diameter, inner bore, keyway, tooth profile, bolt holes, heat treatment and surface treatment.

We have rich experience in OEM/ODM for global railway customers.

Q3: What standards and quality inspections do you follow for railway forgings?

Our railway driven wheels are produced in strict accordance with international standards such as EN, AAR, TB/T or customer-specified standards.

Full inspection includes:

Ultrasonic testing (UT)

Magnetic particle testing (MT)

Hardness test & mechanical property test

Dimensional inspection with CMM
