Chongqing Zhizhan Gear Transmission Co., Ltd. is a professional manufacturer specializing in all kinds of high-precision Gleason and Klingelnberg format spiral bevel gears. Our company is located in Degan Industrial Park in Jiangjin District and benefits from very convenient transportation. The products are widely used in industries such as cement, thermal power, oil drilling, shipping, coal mining, transportation, automotive, and water control etc.
Our company has a complete set of specialized equipments for spiral bevel gear manufacturing and other auxiliary processing equipment. Such as grinding, drilling and milling equipments. The bevel gear tooth profile processing equipment is mainly the American Gleason milling machine, the Gleason grinding machine, and the 3 set of 5-axis machining centers (DMU340P, DMU210P, DMU160P) manufactured by DMG in Germany. Precision gears can be machined up to 3000mm in diameter. Gear shafts are of integral design with no limits on module. Precision level can meet the requirements of DIN5 and the tooth surface hardness is up to HRC58-62. Manufacturing single match of spiral bevel gears can be achieved through the use of our design and processing technology. In the meantime, our company is capable of manufacturing large straight bevel gears, spur gears, and herringbone gears with no undercuts.
Our company insists on technology as the guiding ideology. By fostering our own technical team as well as cooperating with research institutions in the development of arc bevel gears, we have obtained six practical new patents. Our company's "arc bevel gear and gear shaft for 3000kw-above vertical mill reducer" project earns the Chongqing "Key New Product" certificate of honor and the support of the National Science and Technology Innovation Fund. Our company's double-sided transfer twist and high precision spiral bevel gears have been successfully applied to the ship lift of the Three Gorges Dam water control project to have replaced the imported products.
Our company follows the standard management practices with well-established policies. We have passed the ISO9001 quality management system, ISO14001 environmental management system and OHAS18001 occupational health and safety management system certification, which provide a solid guarantee for the healthy development of the enterprise.
A journey of a thousand miles begins with the first step. It is believed that our company's solid starting point of today will become the cornerstone of high-speed growth in the future. It is our cordial hope to grow with the customers together for a better tomorrow.
