Product Description
1)Specialized internal gear rings and chain gear wheel for the coal mining industry
2)Part of the products are made of 18Cr2Ni4WA material,fully ensuring the quality and meeting various harsh working conditions
3)The gear profile is machined by a CNC hobbing machine
4)After high-temperature heat treatment (carburizing and quenching), the tooth surface can meet high hardness requirments, generally between 58- 62HRC, effectively ensuring the strength of the tooth surface
5)The tooth surface after heat treatment is effectively ground to ensure the accuracy of the tooth profile, making the transmission smoother
6)The gear shaft blank is subjected to ultrasonic non-destructive testing and the tooth surface after grinding is effectively ensured to be of good quality through non-destructive magnetic particle testing
7)After finishing the finished gear shaft is coated with a layer of anti rust oil and packaged in wooden boxes to meet the requirements for long-time long-distance transportation and storage
