The high-reliability gears for mining gearboxes developed by Tiandi Benniu feature optimized tooth profile and alignment parameters in their design, which reduces impact and noise during meshing and ensures that the engagement area remains consistently centered. In terms of materials, the company has collaborated with a renowned domestic special steel mill to co-develop materials, fundamentally ensuring the purity of the raw gear materials. This guarantees the structural integrity of the gears under extreme impact and continuous friction, preventing failures such as fractures and pitting. In manufacturing, advanced heat treatment technologies, gear root strengthening shot peening, and precision machining processes are employed to precisely control the internal microstructure of the gears. This achieves an ideal balance between surface hardness and core toughness, significantly enhancing the load-bearing capacity and service life of the gears. These measures ensure that the gears maintain smooth and efficient transmission even under harsh conditions such as high impact and prolonged operation, providing robust and reliable support for the dependable performance of mining gearboxes.
