Abstract

The utility model discloses a pedal drive device for a drying machine. The matching between a planetary gear system and a one-way needle roller bearing is adopted as an intermediate transmission device so as to drive the one-way needle roller bearing to rotate, thus finally realizing the one-way rotation of a drive shaft of the drying machine. Due to the symmetry of the planetary gear transmission structure, a plurality of planetary gears are distributed evenly, so that the counter acting force acted on the one-way needle roller bearing and the planet gears are balanced, thus improving the transmission efficiency; during the rotating process, the acting force generated by the one-way needle roller bearing and the planet gears are balanced mutually, the number of teeth participating in the meshing is increased, the running is stable, the capability of impact resistance and vibration resistance is stronger, the corresponding noise is lower, and the work is more reliable; simultaneously, a ring gear is also taken as a shell of the transmission device, so that the planetary gears and the one-way needle roller bearing are positioned in a relatively sealing space, thus being convenient for using lubricating grease for lubrication, further enhancing the driving efficiency, reducing the noise during the transmission process, and improving the reliability of the device.

Description

Pedal transmission for spin-drier

Technical field

The utility model relates to the mop cleaning device, relates in particular to a kind of pedal driver that is used for the mop drier.

Background technology

After using mop to carry out floor cleaning, generally adopt the mop cleaning device with mop washing, drying, and, can fundamentally solve the inconveniences of bringing when people wash " mop " such as can't cleaning, can't wring out no longer with manually going washing, wringing out; Existing senior mop cleaning device has cleaning function easily at present, when cleaning whole mop is directly put into machine and can clean, and can add thimerosal and make more clean hygiene of mop in the process of cleaning, and also can carry out disinfection to the floor simultaneously; Can adopt dewater unit to dewater after cleaning is finished, the characteristics of this kind cleaning device maximum are cleaned and are dried for finishing, and use more convenient.Adopt of the mop dewater unit of Cai Yonging ridden transmission more in the market, thereby drive drier by stepping up and down of pin and rotate the realization centrifugal dehydration, but the most pedals that adopt of existing pedal driver are stirred tooth bar, tooth bar directly drives the simple mechanism that the gear on the vertical axis rotates, its transmission weak effect, transmission efficiency is low, waste time and energy during use, noise is bigger, the dumb easy formation catching phenomenon of transmission, often cause the drier rotating speed low, make that the mop dehydration is not thorough, whole mop cleaning device is difficult to obtain good result of use.

The utility model content

At above defective, the purpose of this utility model provides a kind of novel pedal transmission for spin-drier, and it has rational frame for movement, the transmission efficiency height rotates flexibly, can significantly reduce the noise of transmission, improve the drier velocity of rotation, easily laborsaving when stepping.

For achieving the above object, the utility model is achieved through the following technical solutions:

A kind of pedal transmission for spin-drier, one rack and pinion drive mechanism is installed on the base, flat tooth by fan tooth on the pedal and tooth bar forms by engagement, form middle transmission system by the ring gear, planet carrier, planetary gear, the unidirectional needle bearing that are fixed on the base, described planet carrier bottom has the planet carrier gear, described planet carrier gear with the drier driving shaft be central shaft and with the perpendicular tooth engagement of described tooth bar side; Axle is loaded on planetary gear and the ring gear engagement on the planet carrier, and meshes with the unidirectional needle bearing that is sleeved on the drier driving shaft simultaneously.

Preferably, described planetary gear is three, becomes equilateral triangle to arrange.

Further, corresponding planet carrier is equipped with the planet carrier cover plate above planetary gear and unidirectional needle bearing.

The beneficial effect of pedal transmission for spin-drier described in the utility model is: adopt epicyclic train and unidirectional needle bearing to cooperate as intermediate gearing, the planetary gear transmission is compared with the ordinary gear transmission, because the symmetry of planetary gear drive mechanism, planetary gear with several well-balanced distributions, the feasible mutual balance of reaction force energy that acts in unidirectional needle bearing and the planetary gear, thus help reaching the effect that improves transmission efficiency; In the rotation process, the mutual balance of active force that unidirectional needle bearing and planetary gear produce, the number of teeth that participates in engagement increases, thus motion steadily, the ability of shock resistance and vibration is stronger, corresponding noise is lower, it is more reliable to work; The shell of while ring gear double as transmission device, make planetary gear be in relative sealed space with unidirectional needle bearing, the convenient lubricating grease that uses is lubricated, and can further strengthen the efficient of transmission, the noise in the reduction transmission process, increases the reliability of device.
