Transmission Structures of Shading System
The transmission structures consist of A-type rack-pinion structure and B-type rack-pinion structure according to the difference of pinions and connection modes
A-type Rack-Pinion Structure
The output shaft of gear motor, connected with driving shaft, revolves with the driving shaft, with which the pinions revolve thereby. The revolution of pinions drives the motions of rack, connected with driving rod that is supported by tube supporter. The reciprocating motions of driving rod can be realized by that of gear motor. And then the folding and unfolding of shading nets, one end fixed at the uprights and the other at the aluminum-leading profiles (connected with driving rod), can be realized.
Main Accessories: gear motor, A-type racks and pinions, welding joint, driving rod, A-type rack-rod connector, tube supporters, etc.
