3, perforation offers the venthole that gas phase is connected to round brush chamber and transmission gear on gear stand, so utilizes ground dataller
The intracavitary negative pressure that can be generated of the round brush distinguished and admirable transmission heat for taking away transmission gear when making reduces gear fever.
Detailed description of the invention
Technical solution in ord to more clearly illustrate embodiments of the present application, below will be to required use in embodiment description
Attached drawing be briefly described, the drawings in the following description are only some examples of the present application, skill common for this field
For art personnel, without creative efforts, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is the structural schematic diagram of double round brush scrubbing brushes in the embodiment of the present application；
Wherein: the first round brush of 1-, the second round brush of 2-, 3- scrubbing brush shell, 4- driving motor, 5- driving gear, 6- gear branch
Frame, 7- transmission gear, 8- spring bearing, 9- venthole.
Specific embodiment
Above scheme is described further below in conjunction with specific embodiment.It should be understood that these embodiments are for illustrating
The application and be not limited to limitation scope of the present application.Implementation condition used in the examples can be done according to the condition of specific producer
Further adjustment, the implementation condition being not specified is usually the condition in routine experiment.
Fig. 1 shows a specific embodiment of this double round brush scrubbing brushes of the application, identical as traditional double roller brush type round brush
, also include: scrubbing brush shell 3, pivot the first round brush 1 and the second round brush 2 being set in scrubbing brush shell 3, line shaft
On be fixedly and coaxially connected the driving motor 4 of driving gear 5, while be sequentially connected driving gear 5 and the first round brush 1 and actively
The gear drive of gear 5 and the second round brush 2.Scrubbing brush shell 3 is formed with round brush chamber, first round brush 1 and the second round brush 2
Receiving is arranged in aforementioned round brush chamber.
In the present embodiment, said gear transmission mechanism include gear stand 6 and pivot be set on gear stand 6 four
A transmission gear 7.
In order to facilitate the structure for describing the scrubbing brush, aforementioned four transmission gear is now referred to as the first transmission gear, the
Two transmission gears, third transmission gear and the 4th transmission gear.Wherein, the first transmission gear and the coaxial fixed company of the first round brush 1
It connects, the second transmission gear is fixedly and coaxially connected with the second round brush 2, third transmission gear and driving gear 5 and the first transmission gear
Connection is engaged simultaneously, the 4th transmission gear engages connect simultaneously with the first transmission gear and the second transmission gear.When driving motor 4
When energization operation, fixed driving gear 5 drives four transmission gears 7 to rotate on motor power axis, and then the first round brush 1 of drive
It is rotated with the second round brush 2.
The key improvements of the present embodiment are, are respectively arranged with one between each transmission gear 7 and gear stand 6
Spring bearing 8, spring bearing 8 greatly reduce the rotary resistance of transmission gear 7, without lubrication for rotating support transmission gear 7
Oil also can guarantee the smooth rotary drive of each transmission gear 7.
Obviously, configuration is there are four above-mentioned spring bearing 8 altogether for four transmission gears 7, this four support shafts in the present embodiment
Hold 8 be rolling resistance very little deep groove ball bearing.
Also, above-mentioned each transmission gear 7 is plastic gear, preferably nylon gear, to reduce in transmission process
Calorific value.
Above-mentioned round brush chamber and each transmission gear 7 are located at the two of said gear bracket 6 away from side, to utilize gear
Transmission gear 7 and two round brush are spaced from each other by bracket 6, and transmission gear 7 and round brush is avoided to interfere with each other during rotation.
Moreover, perforation offers the venthole 9 of gas phase connection round brush chamber and transmission gear 7 on gear stand 6.Scrubbing brush work
When, round brush is intracavitary to generate negative pressure, and negative pressure can be transferred at transmission gear 7 by aforementioned venthole 9, thus in transmission gear 7
Surrounding generation negative pressure is distinguished and admirable, takes away the transmission heat of transmission gear 7 rapidly, reduces gear fever.
In order to guarantee that the transmission fever of each transmission gear 7 can be taken away rapidly, the present embodiment is in each transmission
A venthole 9 is provided at gear 7, totally four ventholes.
