Abstract: A new type of gear transmission with meshed medium belt is developed. The proper tooth profile and tooth thickness calculation method of both the gear and its basic rack are presented. Tests are carried out on the closed electric power test-bed to contrast the performance of this new gear drive with inverlute gear drive, the former lubricated by oil and water separately. According to the tests results some types of medium belts are chosen and performance tests and endurance life tests are carried out. All these tests indicate that the flexible belt can improve the hydrodynamic lubrication of the gears, reduce noises and absorb shocks. The teeth profiles become less damageable, and the requirements on manufacture technics are reduced. Furthermore, this new drive can be lubricated by water.
