[0020] A tooth box of a washing machine comprises a tooth box body 1, wherein a tooth box inner support plate 16 is provided inside the tooth box body 1, and a first gear 2 is rotatably connected to the top front position of the tooth box inner support plate 16, and a second gear 4 is meshedly connected to the upper left position of the first gear 2, fastening bolts 12 are respectively provided on both sides of the first gear 2, and a first rib 3 is provided outside the fastening bolt 12, a third gear 5 is fixedly connected to the top of the second gear 4, a fifth gear 9 is meshedly connected to one side of the third gear 5, and a fourth gear 6 is fixedly connected to the bottom end of the fifth gear 9, a second rib 7 is provided outside the fourth gear 6, and reinforcing columns 8 are respectively fixedly connected to both sides of the second rib 7.

[0021] like Figure 1 , Figure 2 and Figure 3 As shown, the second gear 4 and the third gear 5 are coaxially arranged, and the second gear 4 and the third gear 5 are respectively arranged above the tooth box inner support plate 16, and the front and rear ends of the tooth box body 1 are respectively fixedly connected with side ear plates 11. When the entire tooth box is applied to the washing machine drive assembly, the setting of a group of side ear plates 11 mainly plays a role in assisting the entire tooth box to be quickly bolted and fixedly connected to the washing machine shell; a sixth gear 10 is provided at a top side position of the tooth box inner support plate 16, and a motor coupling 15 is fixedly connected to the center position of the sixth gear 10, and the sixth gear 10 and the fourth gear 6 are meshingly connected. Under the action of the meshing connection, as the motor coupling 15 rotates with the sixth gear 10, the fourth gear 6 will rotate synchronously with the third gear 5 through the fifth gear 9, so as to cooperate with the entire device to achieve linkage; the second rib 7 is arranged in a semi-annular structure, and the second rib 7 is fixedly connected to the tooth box inner support plate 16. Since the second rib 7 and the tooth box inner support plate 16 are fixedly connected to form an integral body, this integral structure can effectively enhance the overall strength of the second rib 7.

[0022] like Figure 1 , Figure 3 and Figure 4As shown, a fan-shaped plate 14 is fixedly connected to one end of the first rib 3 near the fastening bolt 12, and a limiting disc 13 is fixedly connected to one end of the fan-shaped plate 14 away from the first rib 3.
