Abstract
The invention discloses a centrifugal fan round gear transmission adjusting valve, which is composed of a wind cylinder, a small bevel gear, a large bevel gear, a transmission handle, a wind deflector, blades and an inner cylinder, and is characterized in that one ends of the blades are fixed on the wind cylinder, the small bevel gear sleeves on the other ends of the blades, and the small bevel gear is inserted into the shaft hole on the inner cylinder for fixing and mutually matched with the gear of the large bevel gear at the same time; the large bevel gear sleeves on the inner cylinder and is limited and fixed by a pin; the wind deflector seals the two ends of the inner cylinder; the transmission handle is arranged and fixed on the large bevel gear. The centrifugal fan round gear transmission adjusting valve provided by the invention is simple in structure, low in cost, flexible in adjustment, and accordant in operation of the blades.
Description
Technical field
The present invention relates to blower fan technical field, is particularly well-suited to various centrifugal blowers regulation flow pressures and uses.
Background technology
In blower fan technical field, the centrifugal blower for generally using at present adjusts door drive mechanism complexity, adjusts stroke not
Flexibly, easily stuck, Torque-adjusting is big, and regulation door blade angle during regulation is inconsistent, causes to adjust fan performance
There is very big error.
The content of the invention
It is contemplated that overcoming above-mentioned technological deficiency, it is therefore an objective to provide a kind of simple structure, with low cost, flexible adjustment,
The centrifugal fan round gear transmission that blade synchronously can unanimously run adjusts door.
For achieving the above object, the technical solution used in the present invention is：It is by air duct, cone pinion, large bevel gear, transmission
Handle（5）, kuppe, blade, inner core composition；Blade one end is secured by bolts on air duct, blade other end suit small bevel gear
Wheel, it is fixed in the axis hole on cone pinion insertion inner core, while cooperating with the gear of large bevel gear；In large bevel gear is placed on
On cylinder, by the spacing fixation of pin；Kuppe seals at inner core two ends；Transmission handle is mounted on large bevel gear.
Due to adopting above-mentioned technical proposal, present invention achieves using gear-driven special construction.Its transmission is cleverer
It is living, and the inconsistent shortcoming of tradition regulation door blade adjustments is solved, structure installs simple, and driving torque is little.
Description of the drawings
Fig. 1 is that a kind of centrifugal fan round gear transmission of the invention adjusts door schematic diagram；
Fig. 2 is that a kind of centrifugal fan round gear transmission of the invention adjusts door sectional view；
In figure：1st, air duct, 2, bolt, 3, cone pinion, 4, large bevel gear, 5, transmission handle, 6, pin, 7, water conservancy diversion
Cover, 8, blade, 9, inner core.
Specific embodiment
Below in conjunction with the accompanying drawings explanation is described further to invention.
A kind of centrifugal fan round gear transmission adjusts door, and it is by air duct（1）, cone pinion（3）, large bevel gear（4）, pass
Dynamic handle（5）, kuppe（7）, blade（8）, inner core（9）Composition；It is characterized in that blade（8）One end passes through bolt（2）It is fixed on
Air duct（1）On, blade（8）The other end is set with cone pinion（3）, cone pinion（3）Insertion inner core（9）On axis hole in it is fixed,
While and large bevel gear（4）Gear cooperate；Large bevel gear（4）It is placed on inner core（9）On, by pin（6）Spacing fixation；
Kuppe（7）By inner core（9）Two ends seal；Transmission handle（5）It is mounted on large bevel gear（4）On.Realized using this invention
Using gear-driven special construction.Its transmission more flexibly, and solves the inconsistent shortcoming of tradition regulation door blade adjustments,
Structure installs simple, and driving torque is little.
Therefore, the present invention is the centrifugation that a kind of simple structure, with low cost, flexible adjustment, blade synchronously can unanimously run
The transmission of blower fan circular gear adjusts door.
