Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but can not be used for limiting scope of the present utility model.
The structure of the accurate planetary speed reducer of the present embodiment at least comprises as shown in Figure 1 to Figure 2: input shaft 1, front capping 2, one-level ring gear 3, one-level variable block ring gear 4, variable block gear 5, secondary variable block ring gear 6, secondary ring gear 7, secondary planet frame 8, rear seal-cover 9, output shaft 10, primary planet wheel 11, primary planet carrier 12, secondary planet wheel 13 and one-level sun gear and secondary solar gear.Wherein, one-level sun gear, one-level ring gear 3, primary planet wheel 11 and primary planet carrier 12 form primary planet speed reducer.Secondary solar gear, secondary ring gear 7, secondary planet wheel 13 and secondary planet frame 8 form two-stage planetary reduction device.Variable block gear 5 is arranged between primary planet speed reducer and two-stage planetary reduction device, the switching between one-level speed change and two-stage speed change can be realized, this variable block gear 5 is provided with one-level variable block wheel 14, secondary variable block wheel 15 and optical axis 16, optical axis 16 between one-level variable block wheel 14 and secondary variable block wheel 15, and takes turns 14 with one-level variable block, secondary variable block is taken turns 15 and coaxially arranged.Front capping 2 and rear seal-cover 9 are sheathed on input shaft 1 and output shaft 10 respectively, to protect input shaft 1 and output shaft 10.
When planetary speed reducer works, the transmission of power of planetary speed reducer is that the one-level sun gear by being connected with input shaft 1 rotates and drives primary planet to take turns 11 and engages, while engagement, the wheel shaft self of primary planet wheel 11 can rotate around one-level sun gear, and such primary planet carrier 12 just exports rotational power.The variable block gear 5 of planetary speed reducer is to input shaft 1 Slideslip, then secondary variable block wheel 15 (small gears) of variable block gear 5 and secondary planet are taken turns and 13 carried out engagement transferring power, realize two-stage planetary reduction; If instead variable block gear 5 is to output shaft 10 Slideslip, then the secondary variable block of variable block gear 5 takes turns 15 (small gears) and secondary planet wheel 13 disengaging engagement, one-level variable block wheel 14 (gearwheel) of variable block gear 5 engages with secondary variable block ring gear 6 and one-level variable block ring gear 4 simultaneously, then the outputting power of primary speed-down device is directly delivered on secondary planet frame 8 by variable block gear 5, secondary planet frame 8 is fixedly connected with output shaft 10, and the power realizing input shaft 1 is only slowed down by primary planet and is delivered to output shaft 10.Also, namely when one-level variable block wheel 14 and secondary planet frame 8 engage, power is passed to secondary planet frame 8 successively after input shaft 1, one-level sun gear, primary planet wheel 11, primary planet carrier 12 primary speed-down, and is exported by output shaft 10; When secondary variable block wheel 15 and 13 engagement of secondary planet wheel, power is passed to secondary planet wheel 13 successively after input shaft 1, one-level sun gear, primary planet wheel 11, primary planet carrier 12 primary speed-down, and is exported by output shaft 10 after secondary planet wheel 13, secondary planet frame 8 double reduction.
As mentioned above, the accurate planetary speed reducer of one of the present utility model, there is comparatively simple structure, determine that the power that primary planet wheel exports continues to be delivered to two-stage planetary reduction or to be the output shaft directly being outputted to secondary planet wheel by the planet carrier of second planetary reducer by moving around of variable block gear, thus can realize the switching between one-level speed change and two-stage speed change, and then realize variable block.
More than illustrate known, the utility model structure is simple, and the accurate planetary speed reducer that the utility model provides improves the Function Extension of existing planetary speed reducer, improves the use occasion restriction of planetary speed reducer.
Below be only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
