The test turntable is one of the indispensable test equipment for the camera dynamic imaging test. The precision and smoothness of the test turntable directly affect the imaging quality of the camera dynamic photography. From the requirements of the camera to meet the needs of dynamic photography, a brief introduction to the function and structure of the overall structure of the turret test apparatus, turntable drive mechanism through the comparison of several structural programs to determine the worm gear, worm drive and friction wheel drive integrated use of the program, mainly turntable The structure and composition of the drive mechanism, and a preliminary analysis of the transmission error of the drive mechanism of the turntable.
