Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
As shown in Figures 1 and 2, motor with reducing gear described in the utility model, comprise motor body 1, also comprise reducing gear, described reducing gear is arranged on motor body 1, and machine shaft 2 coaxial cooperation on reducing gear and motor body 1, described reducing gear is planetary reducer 3, and described planetary reducer 3 comprises input flange 4, output flange 5, outer sleeve 6, planetary gear mechanism 7, output axle 8; Ring gear 61 is provided with in outer sleeve 6, described planetary gear mechanism 7 to be arranged in outer sleeve 6 and to coordinate with ring gear 61, described input flange 4 and output flange 5 are arranged on the two ends of outer sleeve 6 respectively, and input flange 4 is connected with motor body 1, machine shaft 2 is provided with driven wheel 21, described driven wheel 21 coordinates with planetary gear mechanism 7 through after input flange 4, one end of described output axle 8 is connected with planetary gear mechanism 7, and the other end passes output flange 5.Wherein input flange 4 is except playing the assembling to reducing gear, is also installed on motor body 1 by input flange 4 by whole reducing gear, and screw or bolt usually can be adopted to be connected with motor body 1 by input flange 4.
Wherein, the effect of planetary gear mechanism 7 realizes deceleration transmission, can be provided with multi-stage speed-reducing as required in theory, and every grade of deceleration accordingly arranges corresponding gearratio, is then finally obtained the gearratio of whole planetary gear mechanism 7 by multi-stage speed-reducing.As structure as shown in Figure 1 can be arranged, described planetary gear mechanism 7 has double reduction, primary speed-down is made up of primary planet carrier 711 and the primary planet wheel 712 be arranged on primary planet carrier 711 and one-level sun gear 713, double reduction is taken turns 722 by secondary planet frame 721 and the secondary planet be arranged on secondary planet frame 721 and is formed, described driven wheel 21 and primary planet are taken turns 712 and are coordinated, described one-level sun gear 713 and secondary planet are taken turns 722 and are coordinated, and described output axle 8 is connected with secondary planet frame 721.Like this, the machine shaft 2 of motor body 1 Direct driver is had to drive driven wheel 21 to rotate, and then take turns the matching relationship of 712 due to driven wheel 21 and primary planet, take turns 712 by primary planet can be driven to rotate on ring gear 61, and then drive primary planet carrier 711 and one-level sun gear 713 to rotate, and the rotating speed of driven wheel 21 is primary transmission ratio with the ratio of the rotating speed of one-level sun gear 713; The matching relationship in like manner having one-level sun gear 713 and secondary planet take turnss 722 again drives secondary planet frame 721 to rotate, and then finally drive output axle 8 rotates, and the rotating speed of the rotating speed of one-level sun gear 713 and output axle 8 is only than being secondary transmission ratio.The gearratio of certain whole reducing gear is that primary transmission is than the product with secondary transmission ratio.Certainly, for when being provided with Multi-stage transmission ratio, total gearratio equals each stage gear ratio and is multiplied.
In addition, owing to being usually provided with lubricating oil in outer sleeve 6, in order to play certain binding effect to lubricating oil, improve lubricating oil to the lubricant effect of each gear, play simultaneously and certain restriction is played to the multiple planetary gears in same one-level, generally speaking one-level being provided with three planetary gears, for guaranteeing that these three planetary gears are consistent, partition 9 can being respectively arranged with between input flange 4 and primary planet wheel 712 and between primary planet carrier 711 and secondary planet wheel 722.
In addition, as shown in fig. 1, bearing 10 can be set between output axle 8 and output flange 5, to improve the support effect to output axle 8, certainly, also can arrange further pad 11 and, as structures such as back-up rings 12, its guide ring 12, by being stuck on output axle 8, can realize the limit rotation to output flange 4.
In addition, motor body 1 can adopt various motor in theory, as adopted stepping motor or servomotor.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
