Abstract
A fan impeller comprises a fan blade (1) which is fixedly connected on a fan blade center (2). A reinforced rib (11) with a groove on one side and a protrusion on the other side is stamped on the fan blade (1). By means of the reinforced rib (1) formed on the fan blade (1), strength of the fan blade (1) is improved, requirements of the fan for strength of the fan blade (1) is met, and simultaneously the fan blade (1) of the ventilator is small in self weight so as to reduce loss of kinetic power of the motor.
Description
Technical field:
The utility model relates to the ventilator field, more specifically to a kind of draught fan impeller.
Background technique:
The impeller unit of existing ventilator has a variety of; The fan blade of some impeller is usually made fan blade according to the intensity needs with thick material; Though strengthened the intensity of fan blade like this; But also making needs bigger motor to provide enough kinetic energy to make draught fan impeller rotate, and waste material has also improved the kinetic energy loss of motor simultaneously.
The model utility content:
The purpose of the utility model is exactly the deficiency to existing technology, and a kind of draught fan impeller is provided, and it improves the intensity of fan blade through moulding stiffening rib on fan blade, satisfies the requirement of ventilator to fan blade intensity; Simultaneously, it is little to conduct oneself with dignity, and reduces the kinetic energy loss of motor.
The technological solution of the utility model is following:
A kind of draught fan impeller comprises fan blade, and fan blade is fixedly connected in the fan blade in the heart, and impact briquetting has one side simultaneously to be protruding stiffening rib for groove on the fan blade.
Said stiffening rib is the arc strip, and the groove surface of stiffening rib is molded over the fan blade front, and the crowning of stiffening rib is molded over the fan blade reverse side.
Riveting in the heart in the said fan blade has four fan blades, all forms stiffening rib on four fan blades.
The beneficial effect of the utility model is:
It improves the intensity of fan blade through moulding stiffening rib on fan blade, satisfies the requirement of ventilator to fan blade intensity; Simultaneously, it is little to conduct oneself with dignity, and reduces the kinetic energy loss of motor, energy-conserving and environment-protective.
Description of drawings:
Fig. 1 is the perspective view of the utility model.
Among the figure: 1, fan blade; 11, stiffening rib; 2, fan blade center.
Embodiment:
Embodiment: of Fig. 1, a kind of draught fan impeller comprises fan blade 1, and fan blade 1 is fixedly connected on the fan blade center 2, and impact briquetting has one side simultaneously to be protruding stiffening rib 11 for groove on the fan blade 1.
Said stiffening rib 11 is the arc strip, and the groove surface of stiffening rib 11 is molded over fan blade 1 front, and the crowning of stiffening rib 11 is molded over fan blade 1 reverse side.
Rivet to have on 1, four fan blade 1 of four fan blades on the said fan blade center 2 and all form stiffening rib 11.
Working principle: through on fan blade 1, forming the stiffening rib 11 of arc strip; The intensity and the rigidity of fan blade 1 have been improved; The thickness that need not to improve fan blade 1 improves intensity and rigidity; Needed intensity when so both having satisfied the motor rotation, the kinetic energy that in the impeller deadweight, is consumed when also reducing the motor rotation, energy-conserving and environment-protective.
Claims (3)
1. a draught fan impeller comprises fan blade (1), and fan blade (1) is fixedly connected on the fan blade center (2), it is characterized in that: fan blade (1) is gone up impact briquetting has one side simultaneously to be protruding stiffening rib (11) for groove.
2. a kind of draught fan impeller according to claim 1 is characterized in that: said stiffening rib (11) is the arc strip, and the groove surface of stiffening rib (11) is molded over fan blade (1) front, and the crowning of stiffening rib (11) is molded over fan blade (1) reverse side.
3. a kind of draught fan impeller according to claim 1 is characterized in that: riveted joint is gone up at said fan blade center (2) has four fan blades (1), all forms stiffening rib (11) on four fan blades (1).
