Background technology
Typically with motor as prime mover, rotor and fan rotor respectively have independent bearing positioning and prop up roots blower
Support, is generally attached and transmission by shaft coupling or V belt between motor and blower fan, connected mode referred to as direct-connection transmission or
Band connection transmission.
In existing roots blower technology, rotor and fan rotor are positioned by respective bearing respectively and are propped up
Support, then be driven by shaft coupling or V belt, such blower fan structure product weight and volume are big.
Content of the invention
The purpose of the present invention is to merge motor part and fan section bearing, completes fan rotor simultaneously with a set of bearing
With axially and radially locating for rotor, the structure of roots blower is simplified, reduce product weight and volume.
The problems referred to above of prior art are considered, according to one side disclosed by the invention, the present invention adopts following technology
Scheme：
A kind of roots blower, including rotor 1, trip bolt 2, key 3, bearing 4, driven rotor 5, power rotor 6；
Wherein, the driven rotor 5 and power rotor 6 of roots blower are arranged in parallel, the upper and lower ends of each rotor respectively by
One bearing 4 is axially and radially located, and rotor 1 to be mounted directly to the upper end of power rotor 6, power rotor 6 and electricity
The radially connected place of machine rotor 1 is provided with key 3, the moment of torsion of rotor 1 is passed to power rotor 6, with electricity at the top of power rotor 6
Tightened by trip bolt 2 between machine rotor 1,2 rotation direction of trip bolt is oppositely oriented with power rotor 6, has locking effect.
Beneficial effect：
Present invention achieves rotor and roots blower power rotor axle integral structure, reduce determining for rotor
Position bearing, simplifies product structure, reduces product weight.

Bearing 4 between 6 times shaft shoulders of active lower ball cover 11 and power rotor and active upper ball cover 18 and power rotor 6
Bearing 4 between the upper shaft shoulder, is that power rotor 6 provides radial and axial support；Driven upper ball cover 9 and 5 upper shaft of driven rotor
The bearing 4 between bearing 4 and driven lower ball cover 10 and 5 times shaft shoulders of driven rotor between shoulder, is that driven rotor 5 is provided radially
With axial support.
Bearing 4 on active upper ball cover 18 and power rotor 6 between the shaft shoulder is radially fixed to upper bearing (metal) housing 14, axle
To active upper ball cover 15 is fixed on, active upper ball cover 15 is fixed on fore bearing housing 14 by screw；Active lower bearing
Bearing 4 between 6 times shaft shoulders of lid 15 and power rotor is radially fixed to lower bearing housing 12, is axially fixed to active lower bearing
On lid 11, active lower ball cover 11 is fixed on lower bearing housing 12 by screw；On driven upper ball cover 9 and driven rotor 5
Bearing 4 between the shaft shoulder is radially fixed to upper bearing (metal) housing 14, is axially fixed in driven upper ball cover 9, driven upper ball cover 9
It is fixed on upper bearing (metal) housing 14 by screw；Bearing 4 between 5 times shaft shoulders of driven lower ball cover 10 and driven rotor is radially
Lower bearing housing 12 is fixed to, driven lower ball cover 10 is axially fixed in, driven lower ball cover 10 is fixed to rear axle by screw
Hold on housing 12.
Motor stator 7 is fixed on upper bearing (metal) housing 14, rotor 1 and 6 direct connection of power rotor, is turned round by the transmission of key 5
Square, fixes axially through holding screw 2, the axial gap between the adjustment rotor 1 of adjust pad 8 and motor stator 7, it is achieved that
The support of rotor 1 and positioning, reduce the support positioning bearing of rotor 1, make roots blower structure compacter, subtract
