Also, the use of the terms "a," "an," or "the" and similar referents do not denote a limitation of quantity, but rather denote the presence of at least one. The word "comprising" or "comprises", and the like, means that the element or item listed before the word covers the element or item listed after the word and its equivalents, but does not exclude other elements or items. The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships may also be changed accordingly.

Referring to fig. 1-4, the novel floor mopping machine gearbox comprises a shell 1, wherein a motor 2 is installed on the shell 1, a transmission assembly connected with the motor 2 is installed in the shell 1, the motor 2 is horizontally installed on the shell 1, an output shaft of the motor 2 extends into the shell 1, and a driving bevel gear 20 is installed on the output shaft; the transmission assembly comprises a reversing part, a first coaxial gear 4, an intermediate gear 5, a second coaxial gear 6 and two output gears 7 (provided with rotating shafts 70 connected with the cleaning disc) which are horizontally arranged, straight teeth (namely straight teeth of the disc) are meshed in the transmission assembly, and the radial size of the output gears in each meshing set is smaller than that of the receiving gear.

The reversing part comprises a driven bevel gear 30 and a driven pinion 31 which are coaxially arranged, the driven bevel gear 30 is meshed with the driving bevel gear 20 to complete reversing, a gearwheel on the first coaxial gear 4 and the intermediate gear 5 are respectively meshed with two sides of the driven pinion 31, a pinion on the first coaxial gear 4 is matched with one output gear 7, the intermediate gear 5 is matched with a gearwheel on the second coaxial gear 6, and a pinion on the second coaxial gear 6 is matched with the other output gear 7.

The motor 2 is horizontally placed, the driving bevel gear 20 rotates on a longitudinal plane, the driven bevel gear 30 in the reversing element 3 is horizontally placed to correspond to the driving bevel gear, so that the rotation is reversed to horizontal plane rotation, and the rotation is transmitted by the driven pinion 31 which is coaxially arranged. The straight teeth meshing from the driven pinion 31 to the output gear 7 can effectively avoid the phenomenon that the torque is reduced by vertical component force. The two coaxial gears comprise a large gear and a small gear which are coaxially mounted, available space exists in height when adjacent gear parts are meshed through the difference of radial sizes, the gearbox can be ensured to be thin through horizontal layout, and the layout can be ensured to be compact through height dislocation.

Meanwhile, the radial size of the output wheel in each meshing group is smaller than that of the receiving wheel, namely, the driven pinion 31 is smaller than the bull gear of the first coaxial gear 4, and the pinion of the first coaxial gear 4 is smaller than that of the output gear 7; the driven pinion 31 is smaller than the intermediate gear 5, the intermediate gear 5 is smaller than the large gear of the second coaxial gear 6, and the pinion of the second coaxial gear 6 is smaller than the output gear 7. The gearbox can "amplify" the output torque, the transmitted power (torque x rotational speed) is unchanged, and the torque becomes larger after the rotational speed is reduced. The gear is simplified into a lever for explanation, the contact point of the gear and the gear is the moment arm end of the lever, the circle center of the gear is used as the original point of the lever, and the large gear force arm is long, so that the gear is easy to rotate by external force. Therefore, the gears which are meshed with each other are arranged, so that the transmission ratio is improved, and the output of torque is enhanced.

In some embodiments, a driven pinion 31 is located above the driven bevel gear 30, the driven pinion 31 being smaller in radial dimension than the driven bevel gear 30. Because the driven pinion 31 is smaller, enough space is exposed at the periphery of the driven pinion to be positioned at the driving bevel gear 20, so that the two bevel gears are smoothly meshed, the overall layout is compact, and the occupied space is reduced.

The transmission assembly is asymmetrically equal to the two sides of the motor 2, so that the motor 2 can be arranged at a position slightly deviated to one end outside the shell 1, a side wall of the shell 1 is recessed to form a placing space for the motor 2, a sleeving cavity 12 for fixedly sleeving the motor 2 is arranged at the recessed position, the sleeving cavity 12 is provided with a window communicated with the inside of the shell 1, and an output shaft of the motor 2 extends into the window. The installation position of the motor 2 is formed by the concave of the shell 1, so that the volume of the gearbox can be reduced.

Generally, the housing 1 includes an upper housing 11 and a lower housing 11, the window is formed on the lower housing 11, and the transmission assembly is mounted on the lower housing 11. Therefore, when in assembly, all the parts can be installed on the lower shell 11 and then the upper shell is covered, so that the operation is convenient and simple.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not intended to limit the present invention, which may be modified, combined, and varied by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
