Above-mentioned staircase is with in the art of power transmission scheme, and technical scheme can also be more specifically: the output shaft of said epicyclic gear box is connected with a joggle through the sun wheel of said planetary wheel and said sun wheel shaft.
Further: said pinion carrier is captiveed joint with said casing through bolt.
Further: said internally toothed annulus is captiveed joint with said casing through bolt.
Owing to adopted technique scheme, the present invention compared with prior art, the beneficial effect that has is:
1,, between the pinion shaft of power machine output shaft and conical gear case a parallel offset distance is arranged owing between epicyclic gear box and conical gear case, increased by one group of cylindrical wheel case; The configuration of engine can be satisfied light to the technical requirements of various staircases such as heavy type with power drive.
The diameter that 2, can strengthen flywheel makes it to produce enough big rotor inertia, even staircase can not brake when running into urgent stop immediately, an inertia that slowly slows down is arranged.
3, the engine rotating speed is through three grades of 0.5 meter per seconds that are decelerated to regulation, and reduction ratio increases to 67.2:1 by original 36.2:1, and total driving efficiency is 90%.
4, drg is loaded between epicyclic gear box and the engine, improves the safety that staircase uses with power drive; Engine is realized separating with the star gear case, can realize specialization and large-scale production.
