The utility model discloses a gear driving device for a cleaning robot. The gear driving device comprises a motor and a transmission case connected with the motor, wherein the transmission case comprises a motor support, a motor cover and a gearbox; the gearbox comprises an upper clamping plate, a lower clamping plate and a plurality of gears arranged between the upper clamping plate and the lower clamping plate; the gears comprise a power transmission gear connected with the motor, a first intermediate gear, a second intermediate gear and a power output gear; a rotating shaft of the first intermediate gear, a rotating shaft of the second intermediate gear and a rotating shaft of the power output gear are triangularly distributed, thereby reducing a friction force between the first intermediate gear and the power output gear and further reducing noise generated by the gear driving device; and meanwhile, the service life of the gear driving device is prolonged.
Description
Technical field
The utility model relates to clean robot, especially for the gear drive of clean robot.
Background technology
Clean robot is due to its automatic cleaning energy supply, therefore need to install a plurality of motors, comprise cleaning assemblies (sweep in comprising and sweep on the limit) motor, driving wheel motor and blower motor etc., because motor can produce certain noise in the course of the work, noise when comprising noise that motor itself produces and gear drive work, and topmost noise is from gear drive.
At present, all there is the excessive problem of noise in gear in the gear drive of the clean robot on market, its generally at the noise that sends in when work between 60～80 decibels, and people's decibel in bed is less demanding in 50 decibels, that is to say, the clean robot on market carries out the work meeting in bed the consumer affects its sleep quality.In addition, due to the idler gear that only has in the gear drive of existing clean robot, it directly contacts with power output gear, pressure each other is larger, thereby cause mutual wearing and tearing larger, and then reduced its service life, therefore be necessary to provide a kind of low noise of cleaning machine human, the gear drive of long service life.
The utility model content
The purpose of this utility model is in order to overcome the defective in background technology, provides that a kind of noise is low, the cleaning machine human gear drive of long service life.
In order to achieve the above object, the technical solution adopted in the utility model is as follows:
A kind of cleaning machine human gear drive, the transmission case that comprises motor and connecting motor, described transmission case comprises motor frame, motor cover and tooth case, described tooth case comprise train wheel bridge, lower plate and be arranged on train wheel bridge and lower plate between several gears, described gear comprises power transmission gear, the first idler gear, the second idler gear and the power output gear that is connected with motor, the rotating shaft distribution triangular in shape of wherein, the rotating shaft of the first idler gear, the second idler gear rotating shaft and power output gear.
In prioritization scheme of the present utility model, for keeping the gearratio between the first idler gear and power output gear constant, the radius of described the first idler gear is identical with the radius of power output gear, and namely triangle is isosceles triangle.
In prioritization scheme further of the present utility model, described power transmission gear by change-speed gearing with power transmission to the first idler gear, described change-speed gearing adjustable moving power.
In prioritization scheme further of the present utility model, described power output gear is connected with cleaning assemblies or the driving wheel of clean robot.
Compared with prior art, the beneficial effects of the utility model are:
The rotating shaft that has increased by second idler gear and three gears between the first idler gear of the utility model cleaning machine human gear drive and power output gear is triangularly arranged, reduced the friction side between the first idler gear and power output gear, not only reduce the noise that gear drive sends, also extended its service life simultaneously.

The specific embodiment
Below in conjunction with the specific embodiment and contrast accompanying drawing the utility model cleaning machine human gear drive is further elaborated.
Please refer to Fig. 1 to Fig. 5, be a preferred embodiment of the present utility model.
On the clean robot 1 that the utility model cleaning machine human gear drive 5 is arranged on as shown in Figure 1, described clean robot 1 comprises cover 2 and pedestal 3, sweeps 4 and gear drive 5 in being equipped with on pedestal 3.
Please refer to Fig. 2, gear drive 5 comprises motor 6 and transmission case 7, and transmission case 7 comprises institute's motor frame 8, motor cover 10 and tooth case 9, and tooth case 9 is arranged in space between motor frame 8 and motor cover 10.
As shown in Figure 3, tooth case 9 comprise train wheel bridge 11, lower plate 12 and be arranged on train wheel bridge 11 and lower plate 12 between several gears, described gear comprises power transmission gear 13, the first idler gear 15, the second idler gear 16 that is connected with motor 5 and (sweeps in the present embodiment being with cleaning assemblies 4, also can be the limit sweeps) connected power output gear 17, in addition, power output gear 17 also can be connected and then drive the blower fan rotation with the blower fan (unmarked in the present embodiment) of clean robot 1.
Wherein, the rotating shaft of the rotating shaft of the first idler gear 15, the second idler gear 16 rotating shafts and power output gear 17 is not on same straight line, and distribution triangular in shape (as shown in the dotted line in Fig. 5), therefore the frictional force between above-mentioned three gears is less, thereby has reduced noise and extended service life of gear drive.
Identical with the rotating speed of power output gear 17 in order to guarantee the first idler gear 15, the first idler gear 15 is identical with the radius of power output gear 17, the i.e. rotating shaft of the second idler gear 16 is identical to the distance of the rotating shaft of the rotating shaft of the first idler gear 15 and power output gear 17, that is to say that above-mentioned triangle is to take turns rotating shaft as the isosceles triangle on summit take the second center tooth 16, such design also makes stressed more even between said gear, and frictional force is less.
As shown in Figure 5, in order to regulate the rotating ratio of power transmission gear 13 and power output gear 17, between described power transmission gear 13 and described the first idler gear 15, change-speed gearing 14 is installed.
Above content is in conjunction with concrete preferred embodiment further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field; make without departing from the concept of the premise utility some alternative or obvious modification that are equal to; and performance or purposes identical, all should be considered as belonging to the scope of patent protection that the utility model is determined by claims of submitting to.
