Abstract
The invention discloses a belt transmission mechanism with a variable gear ratio and belongs to the field of belt transmission mechanisms. The belt transmission mechanism comprises rotating shafts, trapezoid revolving bodies, a clamping groove and belts, wherein the belts sleeve the two revolving bodies and are fixed by the clamping groove; a motor drives a screw bolt to move, so as to allow the clamping groove to generate displacement, and accordingly, the belt positions change; and variable speed can be achieved through adjusting the transmission ratio. Moreover, the belt transmission mechanism has the advantages of simple structure, easiness in realization, and no complex equipment, and can realize variable speed as long as the belts sleeve the revolving bodies.
Description
Technical field
The present invention relates to a kind of belt gear, be specifically related to a kind of belt gear of variable gear ratio.
Background technique
Existing gear-shift transmission, the number of teeth are constant, realize that speed change needs the gear of a lot of different numbers of teeth, so just need relatively heaviness and complex apparatus.And present mechanical continuously-variable transmission structure is just more complicated, and transmission efficiency is lower.
Summary of the invention
The object of the present invention is to provide a kind of belt gear of variable gear ratio simple in structure.
A kind of belt gear of variable gear ratio is characterized in that: be made up of driving mechanism and controlling mechanism; Above-mentioned driving mechanism is made up of first rotating shaft, second rotating shaft, the trapezoidal solid of rotation of first rotating shaft that is installed on first rotating shaft, the trapezoidal solid of rotation of second rotating shaft that is installed on second rotating shaft, first belt that is installed on the trapezoidal solid of rotation of first rotating shaft and the trapezoidal solid of rotation of second rotating shaft; Mobile vertically by belt, the two revolving body surface change in radius that contact with belt, thereby the change of realization velocity ratio.Above-mentioned controlling mechanism comprises motor pulley, screw rod pulley, be installed on motor pulley and second belt of screw rod pulley, the motor that links to each other with motor pulley, the screw rod that is fixedly linked with the screw rod pulley; Above-mentioned screw rod is equipped with the belt draw-in groove by thread connecting mode; Above-mentioned first belt is arranged in the belt draw-in groove.
Driven by motor screw motion among the present invention makes draw-in groove produce displacement, allows belt position change, and adjusts and transmits ratio, reaches the effect of speed change.The present invention has simple in structure, is easy to realize, does not need complex apparatus, as long as make belt sleeve just can realize speed change on solid of rotation.
Above-mentioned belt draw-in groove comprises a pair of draw-in groove lamellar body and the draw-in groove reinforced block between the draw-in groove lamellar body; Wherein each draw-in groove lamellar body inwall all is equipped with the draw-in groove cylinder by draw-in groove cylinder fixing device.Draw-in groove moves to touch belt is moved, between will produce friction, belt is wearing and tearing easily just, designed draw-in groove cylinder can move and rotates with belt, the inefficacy that brings with regard to Wear.
