Pedal transmission for spin-drier

Abstract

The invention discloses a pedal transmission for a spin-drier. A planetary gear train is matched with a unidirectional needle bearing to serve as an intermediate gearing to drive the unidirectional needle bearing to rotate so as to finally realize unidirectional rotation of a driving shaft of the spin-drier. A planetary gear transmission structure has symmetry and is provided with a plurality of planet gears which are uniformly distributed so as to make reacting forces acted on the unidirectional needle bearing and the planet gears balanced mutually and improve the transmission efficiency. In the rotating process, the acting forces generated between the unidirectional needle bearing and the planet gears are balanced mutually, the number of teeth participating in meshing is increased, the motion is stable, the impact resistance and the vibration resistance are higher, the corresponding noise is lower and the operation is more reliable. And an annular gear is also used as a shell of the transmission to make the planet gears and the unidirectional needle bearing positioned in a relatively sealing space and facilitate to using lubricating grease to lubricate so as to further increase transmission efficiency, reduce the noise in the transmission process and increase the reliability of the pedal transmission.

Description

technical field [0001] The invention relates to a mop cleaning device, in particular to a pedal transmission device for a mop dryer. Background technique [0002] After using the mop to clean the ground, the mop cleaning device is generally used to wash and dry the mop instead of washing and wringing it manually, which can fundamentally solve the problems that people cannot wash and wring when washing the "mop". Drying and many other inconveniences; the existing advanced mop cleaning device has a convenient cleaning function. When cleaning, the entire mop can be directly put into the machine for cleaning. During the cleaning process, disinfectant can be added to make the mop more clean and hygienic. At the same time, the floor can also be disinfected; after cleaning, the dehydration device can be used for dehydration. The biggest feature of this cleaning device is that it can complete cleaning and drying, and it is more convenient to use. Most of the mop dehydration devices...

Problems solved by technology

Most of the mop dehydration devices currently on the market use pedal transmission, which drives the dryer to rotate through the up and down steps of the feet to achieve centrifugal dehydration. However, most of the existing pedal transmission devices use pedals to move the rack. The simple mechanism that directly drives the gear on the vertical shaft to rotate has poor transmission effect, low transmission efficiency, time-consuming and labor-intensive use, high noise, inflexible transmission and easy to cause stagnation, which often leads to low speed of the dryer and makes the mop If the dehydration is not complete, the entire mop cleaning device is difficult to achieve good results
