[summary of the invention]
The utility model proposes for above problem that volume miniaturization, structure are simple, the synchronous belt wheel transmission device of low cost of manufacture.This synchronous belt wheel transmission device, while meeting same gear ratios, can provide enough large power in less space, meets the needs used.
The synchronous belt wheel transmission device relating to big speed ratio described in the utility model, this synchronous belt wheel transmission device comprises motor, fixed platform, runing rest and two-stage belt wheel transmission mechanism, it is characterized in that, motor is fixed on unsettled runing rest, and driving first order belt wheel transmission mechanism, first order belt wheel transmission mechanism drives the second level belt wheel transmission mechanism of installing on the stationary platform; This runing rest carries motor with the axle center of second level belt wheel transmission mechanism driven wheel for the center of circle rotates.
This first order belt wheel transmission mechanism comprises the first driving wheel and the first driven wheel, this first driving wheel and motor driving shaft coaxial rotation; This second level belt wheel transmission mechanism comprises the second driving wheel and the second driven wheel, is provided with coupling shaft between this second driving wheel and first driven wheel, by coupling shaft two-wheeled coaxial rotation.
This second driven wheel is fixing on the stationary platform.
This runing rest comprises running shaft core bar, motor bearing portion and concentric shafts pole, concentric shafts pole one end is fixed on the coupling shaft of the second driving wheel and the first driven wheel, and the other end is connected in motor bearing portion, this motor bearing portion is fixed on running shaft core bar.
The utility model and traditional motor are installed on the stationary platform, the exceptional space that need take fixed platform is different, motor of the present utility model is arranged on runing rest, without the need to taking the exceptional space of fixed platform, reduces the spatial volume shared by native system further.For the synchronous pulley that diameter is larger, as the second driven wheel adopts the mode of segmentation processing; Without the need to being processed into synchronous belt tooth contour shape, only directly need being processed into halo, or adding anti-slip tank on halo, can ensure equally to transmit precision and effect.
