Description
Technical field
The present invention relates to technical field of mechanical transmission, in particular to a kind of synchronous belt deceleration mechanism.
Background technique
Some transmission mechanisms, such as gear drive, there are gap between the gear teeth of gear, it is poor to will cause certain backhaul, shadow
Transmission accuracy is rung, and the transmission of rigidity will cause impact, have certain damage to mechanism, and transmission ratios will cause greatly biography
Motivation structure it is huge, carry and transport be inconvenient, thus be badly in need of a kind of no backhaul is poor, transmission ratio small to mechanical shocks greatly, structure
Compact transmission mechanism.
Summary of the invention
In view of the above-mentioned problems, passing through the biography of multistage intermediate reduction gear mechanism the present invention provides a kind of synchronous belt deceleration mechanism
Passing keeps mechanism structure simple, and reduction ratio is big, poor without backhaul, improves work efficiency.
Technical solution used in the present invention is: a kind of synchronous belt deceleration mechanism, comprising:
Pedestal；
Shaft is two, and the first from left right side is separately mounted on the pedestal, and is parallel to each other；
Primary sync band mechanism, the big synchronous pulley being rotatably installed in including driving wheel and one in the shaft；Actively
Synchronous belt is arranged between wheel and the big synchronous pulley；
Intermediate reduction gear mechanism is N grades, and every level-one intermediate reduction gear mechanism includes one big synchronous pulley and a small synchronous belt
Wheel；Big synchronous pulley and small synchronous pulley are rotatably installed in respectively in two shafts, are covered on big synchronous pulley and small synchronous pulley
Equipped with synchronous belt；And
Final reduction mechanism, including one big synchronous pulley and a small synchronous pulley, big synchronous pulley are mounted on shaft
On；Small synchronous pulley is rotatably installed in shaft；
Wherein, the small synchronous pulley and primary sync of first order intermediate reduction gear mechanism are fixed with the big synchronous pulley in mechanism
Connection；The small synchronous pulley of second level intermediate reduction gear mechanism and the fixed company of big synchronous pulley in first order intermediate reduction gear mechanism
It connects；And so on, the big synchronous pulley in small synchronous pulley and afterbody intermediate reduction gear mechanism in final reduction mechanism is solid
Fixed connection.
Further, at least one described shaft is movably connected with the base, by adjust two shafts center away from
Adjust the tensile force of synchronous belt.
Further, the big synchronous pulley in the final reduction mechanism is fixedly mounted in shaft, is driven by the shaft
Load output.
Further, the big synchronous pulley in the final reduction mechanism is rotatably installed in shaft；Big synchronous pulley band
Dynamic load output.
Beneficial effects of the present invention: the present invention overcomes transmission mechanism by using the transmitting of multistage intermediate reduction gear mechanism
Due to needing the transmission ratios being driven greatly therefore causing the huge of transmission mechanism, cause to carry and transport inconvenient problem, tool
There is structure simple, reduction ratio is big, poor without backhaul, the advantages that improving working efficiency.It is identical using the synchronous pulley of same size
Synchronous belt, can flexibly change reduction ratio；By adjusting the center of two shafts away from that can quickly adjust belt
Clamp force.
