Steady-state gear structure for roller shade
The structure includes at least one return wheel unit (1) and a power transmission unit (2). The at least one return wheel unit includes a first wheel (12) having a first gear (123), a second wheel (13) having a second gear (133), and a spring (14) mounted between the first wheel and the second wheel. The power transmission unit includes a first driven gear set (22), a second driven gear set (23) and a transmission member (24). The first driven gear set has a third gear (222) which meshes with the second gear and a first bevel gear (223). The second driven gear set has an engaging portion and a second bevel gear (232) meshing with the first bevel gear. The transmission member is connected between the second driven gear set and a driving member which comprises a driving portion. The engaging portion and driving portion may be annular grooves while the transmission member may be a belt mounted between the two.
