Abstract
The utility model relates to a plastics cross flow wind wheel for a blower, consisting of a vane wheel, a bearing, a shaft, a shaft housing, a vibration decreasing fixed ring and bolts of the shaft housing, wherein, the vane wheel consists of a left end closure, a right end closure, a vane and a reinforcing rib; the shaft housing is fixed on the vibration decreasing fixed ring, the utility model is characterized in that the vibration decreasing fixed ring is connected with the right end closure through terminal screws and the bolts of the shaft housing are arranged on the outer side of the vane wheel. By adopting the structure, the utility model has the advantages of long service life, low use-cost and convenient examination and maintenance.
Description
The utility model relates to a kind of wind wheel of gas fan, the tubular wine wheel of being made up of impeller, bearing, axle, axle sleeve that especially uses on air conditioner, the wind curtain machine.
Chinese patent 95246671.6 discloses a kind of plastics tubular wine wheel that is made of end casing, elastomeric joint, retainer ring, set screw, axle sleeve, spindle nose, impeller, packing ring and bearing, be provided with elastomeric joint on the axle sleeve of wind wheel, this elastomeric joint is fixedlyed connected with end casing by retainer ring.Though this plastics tubular wine wheel because of elastomeric joint can absorption portion vibration reduce noise, do not eliminate the vibration that the concentricity difference because of axle and wind wheel causes, thereby elastomeric joint is in all the time in the wind wheel running during oscillation exchange is out of shape, fatigue damage is bigger.And because the elastomeric joint of this wind wheel is non-removable fixedly connected with being connected of wind wheel, in case elastomeric joint damages, whole plastics tubular wine wheel is also scrapped thereupon.And the retaining screw that this rotor shaft puts is positioned at the impeller inboard, is not easy to maintenance and inspection.
The purpose of this utility model provides a kind of long service life, and maintenance and inspection are convenient, and being connected between the plastics tubular wine wheel that user cost is low, the axle sleeve of its rapid wear and wind wheel is dismountable.
The utility model for achieving the above object, it is made of impeller 11, bearing 1, axle 2, axle sleeve 6, vibration damping retainer ring 7, axle sleeve screw 10, described impeller 11 is made up of left end cap 3, right end cap 8, blade 4 and stiffening rib 5, axle sleeve 6 is fixed on the vibration damping retainer ring 7, it is characterized in that: vibration damping retainer ring 7 is connected with right end cap 8 by set screw 9, and axle sleeve screw 10 is positioned at the outside of impeller 11.
After adopting such structure,, only need to change the axle sleeve part and need not change whole wind wheel, prolonged 2～3 times of working lifes, reduced user cost in case axle sleeve damages because being connected between the axle sleeve of rapid wear and the wind wheel is dismountable.And because the axle sleeve screw is positioned at the impeller outside, maintenance and inspection are very convenient.
Now in conjunction with the accompanying drawings and embodiments the utility model is described as follows:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the axial schematic representation of the utility model.
Plastics tubular wine wheel shown in Figure 1 is by being made of impeller 11, bearing 1, axle 2, axle sleeve 6, vibration damping retainer ring 7, axle sleeve screw 10, be connected with vibration damping retainer ring 7 by set screw 9 on the right end cap 8 on impeller 11 right sides, axle sleeve 6 is adhesively fixed on the vibration damping retainer ring 7, and the axle sleeve screw 10 on the axle sleeve 5 is positioned at the outside of impeller 11.
