Description
Technical field
The utility model relates to a kind of mechanical reduction gear, relates in particular to a kind of bi-directional drive back gear of clutch coupling of washing machine.
Background technology
The bi-directional drive back gear of existing decelerating clutch of washing machine mainly contains two kinds:
First kind is parallel axes train bi-directional drive back gear, and the main feature of this kind device is: adopt two groups of duplicate gears to realize three grades of decelerations, and gear is a powdered metallurgical material.It assembles as shown in Figure 1, following centre wheel 11 on the power shaft 13 and following duplicate gear 16 engagements, and following duplicate gear 16 and spline gear 17 engagements, and spline gear 17 and impeller axle 1 are one by splined; Simultaneously, following duplicate gear 16 meshes with last duplicate gear 15 again, last duplicate gear 15 and 14 engagements of dehydrating shaft gear, and dehydrating shaft gear 14 adopts interference fit joint to be connected as a single entity with dehydrating shaft 2.Its structural principle as shown in Figure 2, during the washing state, motor is imported power by belt pulley from power shaft 13, this moment, power shaft 13 rotating speeds were higher, following centre wheel 11 on it forms one-level with following duplicate gear 16 engagements and slows down, form double reductions through following duplicate gear 16 with spline gear 17 engagements again, just obtain with impeller axle 1 that spline gear 17 is connected as a single entity like this and the power shaft 13 identical power that turn to and rotating speed lower.Simultaneously, following duplicate gear 16 forms double reduction with last duplicate gear 15 engagements again, last duplicate gear 15 forms three grades of decelerations with 14 engagements of dehydrating shaft gear, the dehydrating shaft 2 that is connected as a single entity with dehydrating shaft gear 14 just obtains with the power and the rotating speed of power shaft 13 counterturns lowlyer like this, imports the purpose that two-way low speed is exported at a high speed thereby reach.The major defect that this kind bi-directional drive back gear exists is: the parts machining process difficulty is big, the cost height, and speed-reducing clutch final assembly difficulty is big, and the washing noise is poor, and yield rate is low.
Second kind is two cover planetary gear bi-directional drive differential system back gears, and the main feature of this kind device is: adopt two cover planetary gears and a shared internal gear, the deceleration principle is a differential reducing.Its assembling as shown in Figure 3, last centre wheel 5 (tooth number Z a1) on the power shaft 13 and upper planet wheel 6, upper planet frame 7 and shared internal gear 18 (tooth number Z 3) composition I level upper planet train, wherein the last centre wheel on the power shaft 13 5 meshes with upper planet wheel 6, upper planet wheel 6 again with 18 engagements of shared internal gear, upper planet frame 7 is connected as a single entity with impeller axle 1.In addition, following centre wheel 11 (tooth number Z b1), lower planetary gear 10, lower planet frame 8 and shared internal gear 18 are formed II level lower planet train, wherein descend the upper planet frame 7 in centre wheel 11 and the I level upper planet train to be connected as a single entity, following centre wheel 11 and lower planetary gear 10 engagements, lower planetary gear 10 again with 18 engagements of shared internal gear, lower planet frame 8 is fixing, and lower planetary gear 10 is installed on the star axle of lower planet frame 8 and clutch shaft 12, and clutch shaft 12 is connected as a single entity with braked wheel 3.Shared internal gear 18 is connected in one with dehydrating shaft 2.Its structural principle as shown in Figure 4, washing is during state, power shaft 13 directly drives I level upper planet train with rotation speed n 1, makes 7 decelerations of upper planet frame and by the turn to rotation identical with power shaft 13.The impeller axle 1 that is connected as a single entity with upper planet frame 7 is also by the turn to rotation identical with power shaft 13 like this.Simultaneously, upper planet frame 7 drives the motion of II level lower planet train by the following centre wheel 11 that is connected as a single entity with it again, the shared internal gear 18 of lower planetary gear 10 driving I levels and II level is rotated by slowing down with power shaft 13 opposite turning to, like this dehydrating shaft 2 that is connected as a single entity with internal gear 18 also by power shaft 13 opposite turn to rotation, thereby realize the bi-directional drive function.In this kind device, the deceleration of impeller axle 1 and dehydrating shaft 2 does not belong to common planetary gear speed-reduction, but a kind of differential reducing, the revolution speed calculating of impeller axle and dehydrating shaft is as follows: impeller axle rotation speed n 2=n1/[Z3/Za1 * (Za2/Z3+1)+1], dehydrating shaft rotation speed n 3=-n1/[Z3/Za1 * (1+Z3/Za2)+Z3/Za2].The major defect that this kind bi-directional drive back gear exists is: because the shared same internal gear 18 of two cover planet circular systems, the requirement on machining accuracy of internal gear 18 is higher, and internal gear 18 is longer, and the parts machining process difficulty is bigger.Will get out on the clutch shaft 12 in addition and lower planet frame 8 four posts and 4 holes that the star axle matches, these 8 hole required precisions are higher, be difficult to guarantee its uniformity during batch process, make the washing noise uniformity that also is hard to keep.
