Abstract
The utility model relates to a driving device for an agitator type washing machine, which is provided with an input shaft, an output shaft and a speed-reducing mechanism. The input shaft transmits the power to the output shaft through the speed-reducing mechanism; and a box body is arranged outside the speed-reducing mechanism. The speed-reducing mechanism is a planet gear speed-reducing mechanism and is provided with a planet gear retainer, a planet gear and an eccentric shaft. The eccentric shaft is rotationally connected with a slide block; the slide block is connected with a rack in a sliding mode in front and rear directions; left and right directions of the rack are connected on the box body in a sliding mode; on end of the output shaft is connected with an output gear; and the output gear is engaged with the rack. By matching with the eccentric shaft, the slide block and the rack, the driving device converts the rotating power of a driving motor into linear reciprocating motion of the rack, and converts the linear reciprocating motion of the rack into positive and reverse rotation of the output shaft. Therefore, the positive and reverse rotation of an impeller can be controlled without reversely rotating the motor and the service life of the driving motor is greatly prolonged. Due to the adoption of a frame internal tooth structure of the rack, the output gear adopts a sector gear. The driving device for the agitator type washing machine has the advantages of matched interior, space conservation, and smart and reasonable design.
Description
Technical field
The utility model relates to a kind of part of washing machine, particularly a kind of drive unit of agitator type washing machine.
Background technology
Agitator type washing machine impeller under the washing operating mode all is positive and negative rotation, like this can better washing clothes and prevent that clothing from twining, and the rotating of impeller one all be to transfer realization by controller control drive motors positive and negative, this impeller drive unit is because the frequent starting of drive motors and the positive and negative rotation of motor make shorten dramatically the service life of drive motors.
The utility model content
The purpose of this utility model is to provide a kind of drive unit that need not control the agitator type washing machine of impeller by motor positive and inverse.
The technical scheme that realizes the utility model purpose is: a kind of drive unit of agitator type washing machine, have power shaft, output shaft and reducing gear, power shaft sends power to output shaft by reducing gear, reducing gear is provided with casing outward, described reducing gear is the planetary gear reducing gear, have planetary gear retainer and planetary gear and eccentric shaft disposed thereon, the eccentric shaft slide block that is rotationally connected, the slide block fore-and-aft direction tooth bar that is slidingly connected, the tooth bar left and right directions is slidingly connected on the casing, output shaft one end connects output gear, the engagement of output gear wheel and rack.
The tooth bar of the drive unit of above-mentioned agitator type washing machine is the rectangle framework, and its tooth portion is arranged on the framework inboard, and described output gear is a sector gear, and output gear is arranged on the interior engagement of rectangle framework of tooth bar.
The utlity model has following characteristics: (1) the utility model is by the cooperation of eccentric shaft, slide block and tooth bar, the rotary power of drive motors is converted into the straight reciprocating motion of tooth bar, cooperating by tooth bar and output gear again, the straight reciprocating motion of tooth bar is converted into the positive and negative rotation of output shaft, thereby need not rotate the positive and negative rotation that just can control impeller by motor commutation, prolong the service life of drive motors greatly; (2) tooth bar of the present utility model adopts the interior toothing of framework, and output gear adopts sector gear, and inner the cooperation saved the space, and it is ingenious reasonable to design.
Description of drawings
For the easier quilt of content of the present utility model is clearly understood, below the specific embodiment and in conjunction with the accompanying drawings of basis, the utility model is described in further detail, wherein
Fig. 1 is a structure cutaway view of the present utility model;
Fig. 2 is the three-dimensional explosive view of the utility model part.
The specific embodiment
(embodiment 1)
See Fig. 1 and Fig. 2, the utlity model has power shaft 1, output shaft 2 and reducing gear 3, power shaft 1 sends power to output shaft 2 by reducing gear 3, the reducing gear 3 outer casings 9 that are provided with; Described reducing gear 3 is the planetary gear reducing gear, have planetary gear retainer 31 and planetary gear 32 and eccentric shaft 33 disposed thereon, eccentric shaft 33 slide block 4 that is rotationally connected, the slide block 4 fore-and-aft directions tooth bar 5 that is slidingly connected, tooth bar 5 left and right directions are slidingly connected on the casing 9, output shaft 2 one ends connect output gear 6, output gear 6 and tooth bar 5 engagements; Described tooth bar 5 is the rectangle framework, and its tooth portion is arranged on the framework inboard, and output gear 6 is a sector gear, and output gear 6 is arranged on the interior engagement of rectangle framework of tooth bar 5.
During work, drive motors drives power shaft 1 and rotates, power shaft 1 slows down by planetary gear reducing gear 3, simultaneously eccentric shaft 33 drives slide blocks 4 and rotates because slide block 4 above-below directions are slidingly connected on the tooth bar 5, and tooth bar 5 to be left and right directions be slidingly arranged in the casing 9, therefore slide block 4 can be done the cross sliding motion with tooth bar 5, the straight reciprocating motion of tooth bar 5 by with the output gear 6 of its engagement, make output shaft 2 do positive and negative rotation, output shaft 2 drives agitation wheel for washing machine and does positive and negative rotation.
