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, be specially adapted to various centrifugal blower adjust flux pressure and use.
Background technique
In blower fan technical field, the general centrifugal blower adjustment doors drive mechanism using is complicated at present, and adjustment stroke is dumb, easily stuck, Torque-adjusting is large, and adjustment doors is inconsistent in adjustment process Leaf angle, causes fan performance to regulate and have very large error.
Summary of the invention
The present invention is intended to overcome above-mentioned technological deficiency, and object is to provide the centrifugal blower circular gear transmission adjustment doors that a kind of simple in structure, with low cost, flexible adjustment, blade can synchronously unanimously move.
For achieving the above object, the technical solution used in the present invention is: it is comprised of air duct, bevel pinion, large bevel gear, transmission handle (5), air guide sleeve, blade, inner core; Blade one end is secured by bolts on air duct, blade the other end suit bevel pinion, and bevel pinion inserts in the axis hole on inner core fixing, cooperatively interacts with the gear of large bevel gear simultaneously; Large bevel gear is placed on inner core, spacing fixing by pin; Air guide sleeve seals inner core two ends; Transmission handle is mounted on large bevel gear.
Owing to adopting technique scheme, the present invention has realized and has adopted gear-driven special construction.Its transmission is more flexible, and has solved the inconsistent shortcoming of traditional adjustment doors blade adjustments, and structure is installed simple, and driving torque is little.
Accompanying drawing explanation
Fig. 1 is a kind of centrifugal blower circular gear of the present invention transmission adjustment doors structural representation;
Fig. 2 is a kind of centrifugal blower circular gear of the present invention transmission adjustment doors sectional view;
In the drawings: 1, air duct, 2, bolt, 3, bevel pinion, 4, large bevel gear, 5, transmission handle, 6, pin, 7, air guide sleeve, 8, blade, 9, inner core.
Embodiment
Below in conjunction with accompanying drawing, invention is described further to explanation.
A centrifugal blower circular gear transmission adjustment doors, it is comprised of air duct (1), bevel pinion (3), large bevel gear (4), transmission handle (5), air guide sleeve (7), blade (8), inner core (9); It is characterized in that blade (8) one end is fixed on air duct (1) by bolt (2), blade (8) the other end suit bevel pinion (3), bevel pinion (3) inserts in the axis hole on inner core (9) fixing, cooperatively interacts with the gear of large bevel gear (4) simultaneously; It is upper that large bevel gear (4) is placed on inner core (9), spacing fixing by pin (6); Air guide sleeve (7) seals inner core (9) two ends; Transmission handle (5) is mounted on large bevel gear (4).Adopt this invention to realize and adopt gear-driven special construction.Its transmission is more flexible, and has solved the inconsistent shortcoming of traditional adjustment doors blade adjustments, and structure is installed simple, and driving torque is little.
Therefore, the present invention is the centrifugal blower circular gear transmission adjustment doors that a kind of simple in structure, with low cost, flexible adjustment, blade can synchronously unanimously move.
