Specific embodiments
As shown in the figure, (is example with the earth), the sun (1) links to each other with arm (4) by Connection Block (3), and arm (4) passes multilayer transmission shaft (5) center fixation on support (33); Battery (40), motor (35), transmission gear (36), driving pinion group (37) link to each other and are installed in the headstock (34), and headstock (34) is fixed on the support (33); Each layer of driving pinion group (37) is connected with transmission time each respective layer of gear set (38) respectively, and transmission time each layer of gear set (38) fixed with the equivalent layer of multilayer transmission shaft (5) respectively.Fixing relevant planet revolution cantilever (18), planetary rotation pulley disc (6), the directed pulley disc (8) of planet pole axis, satellite revolution pulley disc (7) on each layer of multilayer transmission shaft (5) upper end; The other end of planet revolution cantilever (18) is fixed with copper sheathing (23), the directed drive link (15) of planet pole axis is housed in the copper sheathing (23), the lower end of the directed drive link of planet pole axis (15) is fixed with the directed follower (22) of planet pole axis, and the pole axis (11) of the directed drive link of planet pole axis (15) upper end is through in the axis hole (26) of planet (12); Driving-belt (19) is connecting the planet pole axis orientation follower (22) on directed pulley disc (8) of planet pole axis and the adjacent last layer cantilever (18); The directed drive link of planet pole axis (15) is outer to be with planetary rotation transmission tube (13), and planet autobiography transmission tube (13) lower end is fixed with planetary rotation follower (16); Driving-belt (20) connects revolve round the sun planetary rotation follower (16) on the cantilever (18) of planetary rotation pulley disc (6) and adjacent last layer planet; Transmission tube (13) upper end contacts with planet (12).Be with satellite revolution transmission tube (14) between the directed drive link of transmission tube (18) and planet pole axis (15).Satellite revolution axle sleeve (10) is arranged between planet axis hole (26) and the planet pole axis (11), and satellite revolution axle sleeve (10) is fixed with satellite revolution drive link (24), and satellite revolution drive link (24) upper end is fixed with satellite (25); The lower end of satellite revolution transmission tube (14) is fixed with satellite revolution follower (17); Touch mutually with satellite revolution axle sleeve (10) satellite revolution transmission tube (14) upper end.Satellite revolution pulley disc (7) is arranged, satellite revolution driving-belt, (21) satellite on satellite revolution pulley disc (7) and the upper strata follower (17) that revolves round the sun of ining succession between the directed pulley disc of planetary rotation pulley disc (6) and planet pole axis (8).
When motor (35) drives transmission gear (36) rotation, driving pinion group (37) is also rotated thereupon, and then rotate with the transmission time gear set (38) that driving pinion group (37) is connected mutually, because transmission time gear set (38) is that tower structure contacts with driving pinion group (37), therefore, each gear rotational speed of transmission time gear set (38) differs, from bottom to top by piece to slow, reaching the planet revolution cantilever of fixing with each layer of multilayer transmission shaft (5) (18) with each layer of the transmission time corresponding multilayer transmission shaft of gear set (38) (5) rotates with different speed, from bottom to top from slow to fast, thus formed the revolution state of each planet.Also rotate with the planetary rotation pulley disc (6) that every planet revolution cantilever (18) is connected as a single entity with different speed.Because every adjacent upper strata cantilever (18) is faster than planetary rotation pulley disc (6) rotating speed of following one deck, utilize speed discrepancy up and down, the planetary rotation pulley disc (6) of lower floor rotates by the planetary rotation follower that driving-belt (20) has driven last layer.By of the friction of planetary rotation transmission tube (13) upper end, drive planet (12) rotation, the variation round the clock on the demonstration planet (12) with planet (12).Because just in time equal the directed pulley disc (8) of one deck pole axis down with the girth of the directed follower of the pole axis at cantilever (18) end place (22), because one section arc length that the speed discrepancy when rotating a week with last layer cantilever (18) forms on its periphery.So, be fixed on the angle that the directed follower of pole axis (22) on the planet revolution cantilever (18) is changed owing to revolution, just in time equal the following directed pulley disc of one deck pole axis by angle that driving-belt retracted, so the directed follower of pole axis (22) makes the pole axis of planet can not change direction by the directed drive link of pole axis (15).In planet revolution process, by the directed four seasons variation of demonstrating each planet of the pole axis of planet.
