Description

A washing machine with double pulsators and double drives

(1) Technical field

The utility model relates to a washing machine.

(2) Background technology

The pulsator washing machine is realized by utilizing the pulsator to drive the water flow to rotate periodically, and the rotation of the pulsator is driven by a speed reducer. The existing speed reducer can only drive one wave wheel to rotate, and the washing method is single. At this problem, also someone has proposed double pulsator washing machine, as the Chinese utility model patent No. 200520011686.0 has proposed a kind of double pulsator washing machine, but the gear mechanism design of its deceleration is unreasonable, and the rotation of big pulsator is very slow, reaches There is not the effect of the washing.

(3) Contents of the invention

In order to overcome the above-mentioned shortcomings of the existing pulsator washing machine, the utility model provides a reducer of a double pulsator double-drive washing machine with reasonable structure and good washing effect.

The technical solution of the utility model to solve the technical problem is: a double-wave wheel double-drive washing machine includes a cylinder and a reducer installed in the cylinder, the reducer includes a shell, a The pulley and the power input shaft, the power input shaft extends into the pulley and the housing in turn, and the power input shaft is fixedly connected to the pulley; it also includes a large wave wheel shaft and a small wave wheel shaft sleeved in the large wave wheel shaft , the small wave wheel shaft is connected with the small wave wheel, and the large wave wheel shaft is connected with the large wave wheel; the upper end of the power input shaft is provided with a power gear, and the power gear is connected with four double gears in a circle around its periphery The lower large gear meshes; the lower end of the small wave wheel shaft is connected with a central gear, and the central gear meshes with the upper pinion gear of the double gear that surrounds it in a circle; the lower end of the large wave wheel shaft is connected with a The ring gear sleeve is connected, and the inner wall of the ring gear sleeve is provided with tooth lines. The lower large gear meshes; the four double gears are supported in the gear bracket located in the housing.

Further, water seals are provided between the small wave wheel shaft and the small wave wheel, and between the large wave wheel shaft and the large wave wheel.

The gear bracket is integrated with the housing, and the gear bracket can also be detachably connected with the housing.

When the utility model is in use, the pulley is driven by the transmission belt to rotate, the rotation of the pulley drives the power input shaft to rotate, and the power gear on the upper end of the power input shaft rotates accordingly, and the power gear thus drives the double gear meshed with it to rotate. The upper pinion of the gear drives the central gear to rotate. The rotation of the duplex gear drives the ring gear sleeve to rotate. When the ring gear sleeve rotates, the large wave wheel shaft rotates thereupon; while the central gear rotates, the small wave wheel shaft rotates thereupon. Since the rotation direction of the sun gear is opposite to that of the duplex gear, the rotation directions of the large wave wheel and the small wave wheel are also opposite.

The beneficial effects of the utility model are as follows: 1. The big and small pulsators can rotate in opposite directions to achieve the effect of scrubbing. 2. The gear transmission structure of the reducer is designed reasonably, which can keep the speed of the pulsator at the optimum speed of 160 rpm.

Fig. 1 is a structural representation of the utility model.

Fig. 2 is a structural schematic diagram of the pulsator.

(5) Specific implementation methods

The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment.

Referring to Fig. 1 and Fig. 2, a washing machine with double pulsators and double drives includes a cylinder body 15 and a reducer installed in the cylinder body 15, and the reducer includes a casing 1, a The pulley 2 and the power input shaft 3, the power input shaft 3 extends into the pulley 2 and the housing 1 in turn, and the power input shaft 3 is fixedly connected to the pulley 2;

Also includes the big wave wheel shaft 4 and the small wave wheel shaft 5 sleeved with the big wave wheel shaft 4, the small wave wheel shaft 5 is connected with the small wave wheel 6, the large wave wheel shaft 4 is connected with the big wave wheel 7, and the small wave wheel shaft 5 is connected with the small wave wheel shaft A small water seal 8 is provided between the small wave wheel 6, and a large water seal 9 is provided between the large wave wheel shaft 4 and the large wave wheel 7;

The upper end of the power input shaft 3 is provided with a power gear 10, and the power gear 10 meshes with the lower large gear of four double gears 11 surrounding it in a circle;

The lower end of the wavelet wheel shaft 5 is connected with a central gear 12, and the central gear 12 meshes with the upper pinion of the duplex gear 11 surrounding it in a circle;

The lower end of the big wave wheel shaft 4 is connected with a ring gear sleeve 13, and the inner side wall of the ring gear sleeve 13 is provided with tooth lines, and the outer ring gear sleeve 13 is connected with the four double gears 11. The teeth pattern on the inner side wall of the snare 13 meshes with the lower large gear of the double gear 11;

The four double gears 11 are supported in a gear bracket 14 located in the housing. In this embodiment, the gear bracket 14 is integrated with the housing 1 . Of course, the gear bracket is detachably connected to the housing. For example, a bayonet is provided on the gear bracket, and a locking block is provided in the housing. When assembling, the locking block can be stuck in the bayonet.

When the utility model is in use, the pulley 2 is driven by the transmission belt to rotate, the rotation of the pulley 2 drives the power input shaft 3 to rotate, and the power gear 10 on the upper end of the power input shaft 3 rotates accordingly, and the power gear 10 thus drives the double gear meshed with it. Link gear 11 rotates, and the upper pinion of double link gear 11 drives central gear 12 to rotate again. The rotation of the duplex gear 11 drives the ring gear sleeve 13 to rotate, and when the ring gear sleeve 13 rotates, the large wave wheel shaft 4 rotates thereupon; when the central gear 12 rotates, the small wave wheel shaft 5 rotates thereupon. Since the rotation direction of the central gear 12 is opposite to that of the duplex gear 11, the rotation directions of the big wave wheel 7 and the small wave wheel 6 are also opposite.
