FIELD: engineering industry. ^ SUBSTANCE: invention refers to engineering industry, and namely to gears for stepless speed control of output member movement. Cam pulse variator consists of a housing, and drive shaft, driven shaft, and converting mechanisms located therein, each of which includes a cam installed on drive shaft, a lever interacting with the cam and having the possibility of swinging, a spring, free wheel mechanism located on driven shaft, and control mechanism. Lever consists of a quadrant, and free wheel mechanism includes ring gear kinematically connected by means of gear to the lever quadrant; at that reference diameter of lever quadrant is bigger than reference diameter of free wheel mechanism ring gear. Converting mechanism includes swinging carrier installed with one of its ends on driven shaft, and with the other one - on the lever axis. Control mechanism includes the axis installed in the housing, and on the axis there fixed is a fork with thrust flanges, each of which interacts with the appropriate converting mechanism. ^ EFFECT: providing the possibility of obtaining not only reduction but also acceleration mode, and minimising the impact of unbalanced moving masses of the device on the device housing. ^ 3 dwg |
