Specific embodiment
Combined with specific embodiments below, the content of the utility model is described in further detail:
In order to reach the purpose of this utility model, Fig. 1 shows the first embodiment low noise dust suction of the utility model
The structural schematic diagram of device round brush, mainly by integral rolling brush 1, bearing block 2, bearing 3, roller brush shaft 4, left and right end cap 51, right end cap 52
And it is fixed on integral rolling brush 1；Integral rolling brush 1 is near cylindrical hollow structure, wherein having one section of indent close to central region, this is set
The main purpose set is for the ease of the installation of round brush driving gear；Bearing block 2 is assemblied in round brush by way of interference fit
In body 1；Roller brush shaft 4 is assemblied in integral rolling brush 1 by bearing 3, bearing block 2；By the shaft shoulder at the left and right both ends of roller brush shaft 4 come
Position the bearing 3；In order to reduce vibration, noise caused by assembly as far as possible, need to ensure roller brush shaft 4, bearing after the assembly is completed
3, the shaft centre line of bearing block 2 and integral rolling brush 1 coincides；It is respectively arranged with left and right end cap 51,52 at the both ends of roller brush shaft 4, it should
There are the gaps 3-5mm between end cap and the mutual fitting of roller brush shaft 4 and left and right end cap 51,52 and the end face of integral rolling brush 1；Bearing
The bearing 3 assembled in seat 2 is plastic bearing.Due to it with low noise, self-adjusting ability is strong, self-lubrication, wear-resisting, low rubs
The features such as wiping.Therefore, in dust collector rolling brush practical work process, its operational vibration and noise can be lowered significantly.
Shown in Fig. 2 is the cross-sectional view of second of embodiment bottom bracket of the utility model.Itself and Fig. 1 low noise dust suction
The difference of device roller brushes structure is only in that arranges resilient sleeve 21, so, axis in the inner hole of bearing block 2 in a manner of heating
It holds to be elastically engaged between 3 and bearing block 2, resilient sleeve 21 is fixed with hot melting way and 2 phase of bearing block, though manufacturing process is multiple
Miscellaneous, cost is opposite can be high, but this mode amalgamation is good, and it deforms consistency and uniformity is best, can basis
The practical set situation of roller brush shaft 4, bearing 3 and bearing block 2 comes the positional relationship and axial direction that in real time, adaptively adjust above-mentioned three
Center line concentricity, thus reduce from source the vibration and noise of dust collector rolling brush.On the other hand, elastic component inherently has
There is vibration damping, absorb the functions such as noise.It, can also be in bullet in addition to above-mentioned resilient sleeve 21 is fixed with hot melting way and 2 phase of bearing block
Property set 21 and associated bearing block 2 on open up bolt hole, the mode being connected by bolts is secured together.
Shown in Fig. 3 is the partial sectional view of dust collector rolling brush in the third embodiment of the utility model, in Fig. 2
The difference of second of embodiment is only that be secured on the corresponding contact surface of structure on left end cap 51, right end cap 52
It is provided with buffering plastic parts 6, which selects soft rubber.The buffering plastic parts is mutually glued with left and right end cap respectively, can also be with
For other any suitable connection types.By the way that buffering plastic parts is arranged on left and right end cap, to further decrease round brush in height
Since the centrifugal action of round brush causes end cap to be secured to the noise that structure generates when speed operating.
The foregoing description of the disclosed embodiments can be realized professional and technical personnel in the field or using originally practical new
Type.Various modifications to these embodiments will be readily apparent to those skilled in the art, and determine herein
The General Principle of justice can be realized in other embodiments without departing from the spirit or scope of the present utility model.Cause
