Description of drawings
For above-mentioned purpose of the present invention, feature and advantage can be become apparent, below in conjunction with accompanying drawing the specific embodiment of the present invention is elaborated, wherein:
Fig. 1 is a kind of existing speed reducer Transmitted chains schematic diagram.
Fig. 2 is the speed reducer Transmitted chains schematic diagram of one embodiment of the invention.
Fig. 3 illustrates tooth bar schematic representation shown in Figure 2.
Embodiment
Fig. 2 is the speed reducer Transmitted chains schematic diagram of one embodiment of the invention.With reference to shown in Figure 2, the structure that the kind of drive of speed reducer 200 adopts planetary differential deceleration, parallel axes and planetary reduction gear to cooperate successively, its middle gear 201～203 is formed the planetary differential reducing gear, it has an input end and two output terminals, wherein input end connects the output shaft of motor, two output terminals are outputting power respectively, to carry out power bi-shunting.Left part gear 204～208 is formed the first parallel axes reducing gear, and its input end connects a wherein output of planetary differential reducing gear, and left part gear 211～216 is formed first planetary gear speed reducing mechanism, and its input end connects the output of the first parallel axes reducing gear.Right part gear 405～410 is formed the second parallel axes reducing gear, and its input end connects another output of planetary differential reducing gear, and right part gear 411～416 is formed second planetary gear speed reducing mechanism, and its input end connects the output of the second parallel axes reducing gear.In the present embodiment, first planetary gear speed reducing mechanism and second planetary gear speed reducing mechanism are that secondary planet is slowed down, and this can improve speed ratio, but this is not as qualification of the present invention.Under different speed ratio demands, other embodiments of the present invention still can adopt various other planetary reduction gears of level.
Speed reducer 200 is by the single output of motor, and actuation gear 201, gear 202 and gear 203 are exported simultaneously, realizes that left and right two transmission branch roads shunt with rotating speed with power.Wherein, gear 202 drives right part gear 205～217, thereby drives tooth bar 218; Gear 203 drives left part gear 204～208 and gear 211～217, thereby drives tooth bar 218.The schematic representation of tooth bar 218 as shown in Figure 3.Because the planetary differential reducing gear is two-freedom output, can eliminate tooth bar processing and installation errors voluntarily, so the output of left and right transmission branch road is synchronously, therefore two gears 217,417 that climb can be realized meshing simultaneously with tooth bar 218, drive tooth bar 218 simultaneously.The gear transmission progression of speed reducer 200 is more, can realize the deceleration of large speed ratio.Be positioned at two gears the 217, the 417th that climb of the output terminal of first planetary gear speed reducing mechanism and second planetary gear speed reducing mechanism, be with the hollow output shaft of internal splines to drive respectively by two, and link to each other with tooth bar 218, this can realize that load evenly distributes and power dividing between two gears 217,417.Therefore, present embodiment can realize that large speed ratio transmission, power bi-shunting reach with load output, and structural configuration is simple and clear.
In one embodiment, by changing the transmission progression of left road, right wing parallel-axes gears, can realize the rotation in the same way and the backward rotation of two little gears 217,417 that climb, two gears 217,417 can be placed on the homonymy of tooth bar 218 when rotating in the same way, and two gears 217,417 can be placed on the heteropleural of tooth bar 218 during backward rotation.
The above embodiment of the present invention, compared with prior art, its advantage is:
1, utilizes the structure of planetary differential deceleration+parallel-axes gears deceleration+planetary reduction gear, realize that large speed ratio slows down, power bi-shunting reaches and exports with load;
2, the differential planetary reducer structure is arranged in speed end, two conditions that gear all carries had both been satisfied, the load that makes planet partly bear again is less, therefore, it is less that the modulus of gear 203 and boundary dimension can design, and then gear 203 boundary dimension are subjected to the influence of mechanics limit less, and the gear ring flange thickness can obtain raising by a relatively large margin, thereby make the distortion of gear ring work in-process control easily, significantly improved manufacturability;
3, compare for the situation of single engagement with gear 112 with Fig. 1 middle gear 111, embodiments of the invention adopt gear 214～216 to form the mode of planetary structure output, utilize planet many to tooth engagement and the little advantage of volume, can reduce the modulus and the boundary dimension of output gear effectively, the layout that had both helped mechanism, reduce difficulty of processing again, reduced cost of production.
The speed reducer of the embodiment of the invention can be used for realizing bigger speed ratio in the lifting system of similarity such as ocean platform, and the lifting system that guarantees platform is reliably working steadily.
Though the present invention discloses as above with preferred embodiment; right its is not in order to qualification the present invention, any those skilled in the art, without departing from the spirit and scope of the present invention; when can doing a little modification and perfect, so protection scope of the present invention is when with being as the criterion that claims were defined.
