Embodiment Construction

[0034] The embodiment of the present invention discloses a large transmission ratio mute gearbox, which includes a motor drivingly connected with a first pulley, the first pulley is drivingly connected with a second pulley, wherein the second pulley is also used as a planetary gear train. The planet carrier is used as the power input end of the planetary gear train; the planetary gear train includes a plurality of planetary gears that can be relatively eccentrically installed on the second pulley, and at the same time each planetary gear is respectively connected with the sun gear; It revolves under the driving of the second pulley, and drives the sun gear to rotate eccentrically relative to the second pulley, and the sun gear mandrel fixed with the sun gear serves as the power output end of the gear box.

[0035] In order to make those skilled in the art better understand the technical solutions of the present invention, the technical solutions in the embodiments of the presen...

Abstract

The invention discloses a large-transmission-ratio mute gear box machine and a sweeper applying the same. The large-transmission-ratio mute gear box machine comprises a motor in driving connection with a first belt wheel, and the first belt wheel is in transmission connection with a second belt wheel, wherein the second belt wheel serves as a planet carrier of a planetary gear train at the same time, and the planet carrier serves as the power input end of the planetary gear train; the planetary gear train comprises a plurality of planetary gears which can be mounted on the second belt wheel ina relatively eccentric rotating manner, and meanwhile, each planetary gear is in transmission connection with a sun gear; and the planetary gears are driven by the second belt wheel to revolve and drive the sun gear to eccentrically rotate relative to the second belt wheel, and a sun gear mandrel fixedly installed on the sun gear serves as the power output end of the gear box. The large-transmission-ratio mute gear box machine has the technical effects of being compact in installation structure and capable of achieving large transmission ratio and silent transmission, and therefore the large-transmission-ratio mute gear box machine is particularly suitable for being used as a gearbox structure of the sweeper (including a sweeping robot).

Description

technical field [0001] The invention belongs to the technical field of transmission, and in particular relates to a large transmission ratio mute gearbox, and also relates to a sweeper to which the gearbox is applied. Background technique [0002] With the continuous pursuit of improving living standards and the continuous innovation of cleaning technology, sweepers with automatic cleaning effects (including sweeping robots) are more and more widely used in people's daily life. [0003] As the drive installation structure of the sweeper, the performance of the gearbox will directly determine the installation volume and noise performance of the sweeper. However, the existing gear box generally adopts the gear meshing type gear box structure. During the driving process, the noise generated by the gear meshing is relatively large; and when a large transmission ratio is required, a multi-stage gear installation structure needs to be adopted, which takes up a lot of installation ...
