The transmission shaft of the subway door system needs to withstand high-frequency switch impacts. The hardened layer of traditional carburizing treatment is thin (≤ 0.8mm), which is prone to fatigue wear, resulting in door switch jamming and a service life of only 3-5 years, affecting the safety of subway operation.
The Daokedao laser cladding equipment adopts local precision cladding technology to melt a high hardness wear-resistant coating on the force bearing part of the transmission shaft, with a hardened layer depth of 1.5-2mm and a stable hardness of HRC60-63. The device has a low heat input and a transmission shaft deformation of ≤ 0.01mm, ensuring transmission accuracy.
The service life of the strengthened transmission shaft has been extended to 8-10 years, the fatigue strength has been increased by 50%, and the failure rate of subway door switches has been reduced by 95%. After adopting this technology, a certain subway operating company saved over 800000 yuan in annual operation and maintenance costs, improving operational safety and comfort.
