3=24.The setting of layer dividing plate 6 is mainly in order to prevent internal-external gear vibration; and the internal gear of each layer drive structure all trackslips under its corresponding layer dividing plate by its natural trajectory; wherein can select in third layer drive structure need not layer dividing plate 6; because the internal gear 3 ' that third layer and last one deck and torque output shaft 8 connect firmly can System of Rotating about Fixed Axis on the base of stake body 4, thus limited location effect plays the effect of layer dividing plate.The external gear 1 of internal gear control mechanism ground floor structure connects firmly with torque input shaft 7, external gear 2 in second layer structure connects firmly with the internal gear 1 ' coaxial line of ground floor, external gear 3 in third layer structure connects firmly with the internal gear 2 ' coaxial line of the second layer, thus the speed such as acquisition rotate; Stake body 4 is primarily of bearing 4-1, and sealing plate 4-2, gland 4-3, mounting flange 4-4 form, and wherein mounting flange 4-4 is fixed on above transformer box cover 9, is transformer oil 10 below transformer box cover 9.Torque output shaft 8 is primarily of main shaft 8-1, bearing 8-2, oil sealing 8-3 forms, the handle seat 5-1 that handlebar 5 connects firmly primarily of one end and torque input shaft 7, wear axle between one end with handle seat another end to be connected and reflexibie shaft arm 5-2, wear axle between one end with shaft arm to be connected and reflexibie handle 5-3 forms, wherein handle seat 5-1 is seated on layer dividing plate 6-1, handle seat 5-1 and torque input shaft 7 connect firmly, torque input shaft 7 and external gear 1 connect firmly, and during handle 5-3 non operating state, across-layer dividing plate 6 is retractable in the inside of stake body 4.
Embodiments of the invention operating process:
When needs adjustment gear, the handle 5-3 being positioned over layer dividing plate 6 inside is upwards proposed and rolls over turnback, rocking handle is 5-3, the handle seat 5-1 be connected with shaft arm one end is driven to rotate by shaft arm 5-2, because handle seat 5-1 and torque input shaft 7 connect firmly, therefore torque input shaft 7 is driven to rotate, torque input shaft 7 drives internal gear 1 ' to trackslip by its natural trajectory under layer dividing plate 6-1 by the external gear 1 connected firmly with it, and drive the external gear 2 connected firmly mutually with internal gear 1 ' to rotate, external gear 2 drives internal gear 2 ' to trackslip by its natural trajectory under layer dividing plate 6-2, and drive the external gear 3 of the lower one deck connected firmly mutually with internal gear 2 ' to rotate, external gear 3 just drives internal gear 3 ' to rotate, because internal gear 3 ' and torque output shaft 8 connect firmly, the speed such as its coaxial line are driven to rotate, and the main shaft that itself and shunting switch are fixed wtih movable contact spring connects firmly, so can make shunting switch movable contact spring circumference switch each shunting tap different from transformer coil connect determine contact conducting, realize the Voltage Cortrol to transformer.
The feature of the technical scheme of application claims protection is a regular structure: its regularity is a kind of N layer internal gear structure, and transmission is transmitted layer by layer, and gearratio then successively decreases layer by layer, but instead the gearratio of last one deck is greater than the first floor.If turned to mathematical expression to represent: Z '
