Tsubaki Everbest Gear (Tianjin) Co., LTD. (TEG) was established in 1990. It is a sino-foreign joint venture company which is mainly specializing in designing and manufacturing worm gear reducers. The Tianjin Committee of Science and Technology has designated TEG as a "New High Technology Enterprise of Tianjin". The plane enveloping toroidal worm gear reducers designed and manufactured by our company have received many prizes. These kinds of reducers have been promoted as the substitution products for the old generation of reducers by the Ministry of Machinery Industry. The toroidal worm CNC system has also been listed as one of the outstanding projects of the National Significant Achievement Bulletin. Authorized by the former State Bureau of Machinery industry, the Mechanical professional standard of the People's Republic of China JB/T 9051-2000 "Planar Enveloping Worm Gearing Reducers" was drafted out by our company. Now, this standard has already taken effect.

TEG has the world's leading theory and technology in the territory of the plane enveloping toroidal worm transmissions. Our company has also obtained numbers of multinational invention patents. We always believe that technology is the main power for the development of a company. As a reason of that, cooperated with German Klingelnberg company, TEG developed five world's only HNC35TP worm grinding machines which were equipped with 10 CNC axis and 4 simultaneously working axis.

In order to match these high precision equipments, our company had imported several models of gear hobbing machines and numbers of CNC machining centers. We also equipped with imported meshing analysis equipment and 3-D high precision measuring machine. In addition, the company had setup the computer-aided experiment rig, friction and wear testing laboratory, noise and vibration analysis system, etc. for completely testing the performance of our products.

The plane enveloping toroidal worm reducers produced by our company can achieve Grade 5 of DIN standard. These reducers have many kinds of advantages, such as: high transmission efficiency, large loading capacity, low noise level as well as high precision, etc. These high precision and low noise reducers and worm gear sets are not only sold in the domestic market, they have also been exported to many countries in the world.
