Abstract

The invention relates to a transmission ratio gradually-changed system which comprises driving gears and driven gears. The driving gears and the driven gears are mutually meshed. The number of teeth of the driving gears is gradually changed and the driving gears are distributed in a spiral shape. The driving gears which are distributed in the spiral shape are arranged on driving gear shafts. The driven gears are arranged on driven gear shafts. The transmission ratio gradually-changed system can achieve the purpose of continuously adjusting the transmission ratio of a transmission system in real time with high precision and overcome the defects of being complex in structure, troublesome in assembly and maintenance, high in cost and the like. The transmission ratio gradually-changed system has the advantages of being simple and reasonable in structure, high in movement precision, high in transmission efficiency, convenient to operate, control and maintain, little in vibration, low in cost and the like. The requirement of a gradually developed electromechanical device can be met, and a wide application range is achieved in the electromechanical field.

Description

technical field [0001] The invention belongs to the technical field of transmission systems, and relates to a transmission ratio adjustment system, in particular to a transmission ratio gradual change system. Background technique [0002] At present, gear transmission is widely used in various electromechanical equipment or instruments. It is used to transmit motion and power between two shafts. Compared with other mechanical transmissions, it has the advantages of compact structure, stable operation and less noise. However, with the continuous improvement of the requirements for the performance and development of electromechanical equipment, higher requirements have been put forward for the adjustment of the transmission ratio, the precision of the adjustment of the transmission ratio and the related control. In the existing precision gear transmission, it is difficult to continuously and accurately adjust the transmission ratio of the transmission system in real time, and ...
