Abstract
The utility model relates to a taper sleeve expansion shaft disk, which belongs to a connecting part, in particular to a connecting part used for a fan main shaft and an impeller. The utility model is characterized in that the shaft disk is provided with a shaft disk hole; a taper sleeve is sleeved in the shaft disk hole; and the taper sleeve is vertically provided with a notch. In the utility model, the taper sleeve is sleeved in the shaft disk hole and the main shaft is arranged in the taper sleeve, great convenience is brought to the detachment and the installation of the impeller, and the service life of the impeller is prolonged. The axial length of the shaft disk is shortened, and the weight of the shaft disk is reduced by 40 percent, and thereby, the weight of the impeller is reduced, the length of the main shaft is shortened and the manufacturing cost of a fan is reduced.
Description
Technical field:
Tapered sleeve swelling reel belongs to a kind of coupling, in particular for the coupling of blower fan main shaft and impeller.
Background technique:
At present, being used for the reel that blower fan main shaft connects with impeller, is that the reel hole is arranged on reel, and the reel hole connects main shaft, the moment of torsion of main shaft will lean on the flat key in the reel hole to transmit, and in order to reach required torque, the axial length of reel is just very long, cause the reel materials many, Heavy Weight, cost height.This reel has reached the requirement of rigidity and intensity, but disassembly is too poor, often all will carry out " major operation " to blower fan for changing impeller and bearing, and the main shaft of also having to destroy sometimes influences the normal use of equipment.
Summary of the invention:
Problem to be solved in the utility model is exactly the blower fan reel that a kind of easy accessibility is provided at above deficiency.Its technological scheme is as follows:
It is that the reel hole is arranged on reel, is with a tapered sleeve in the reel hole, vertically has breach on the tapered sleeve.
Compared with prior art the utlity model has following beneficial effect:
1, the utility model is with tapered sleeve in the reel hole, and main shaft is installed in the tapered sleeve, only need unclamp bolt during the dismounting impeller, and the dismounting tapered sleeve has just brought incomparable convenience for the dismounting of impeller, has prolonged the working life of impeller.
2, when with bolt with tapered sleeve when the reel hole compresses, owing to vertically have breach on the tapered sleeve, the endoporus of tapered sleeve dwindles naturally and holds main shaft tightly, it is big that the moment of torsion that the torque ratio flat key that this power of holding tightly is transmitted transmits is wanted, because tapered sleeve reel driving torque is greater than the driving torque of flat key, so the axial length of reel can shorten, make the weight saving 40% of reel, so not only alleviate the weight of impeller, also shortened the length of main shaft, reduced the manufacture cost of blower fan.
3, the shorten length of the axial length of reel and main shaft is quite useful to the gas that flows in impeller.
Description of drawings:
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model assembling schematic representation.
Embodiment:
Referring to Fig. 1, the utility model is that reel hole 6 is arranged on reel 1, its key technology is to be with a tapered sleeve 3 in reel hole 6, vertically have breach 5 on the tapered sleeve 3, have semicircle screw 2.1 at reel hole 6 inwalls, have semicircle step unthreaded hole 2.2 at tapered sleeve 3 outer walls and match, insert bolt 4 in the hole with the semicircle screw 2.1 of reel hole inwall.When connecting main shaft, main shaft is inserted the endoporus of tapered sleeve 3, and bolt 4 compresses tapered sleeve to the reel hole, owing to vertically have breach 5 on the tapered sleeve 3, the endoporus of tapered sleeve 3 dwindles naturally and holds main shaft tightly.
Claims (2)
1. a tapered sleeve swelling reel has reel hole (6) on reel (1), it is characterized in that being with a tapered sleeve (3) in reel hole (6), vertically has breach (5) on the tapered sleeve (3).
2. according to the described tapered sleeve swelling of claim 1 reel, it is characterized in that having semicircle screw (2.1) at reel hole (6) inwall, have step unthreaded hole (2.2) at tapered sleeve (3) outer wall and match, insert bolt (4) in the hole with the semicircle screw (2.1) of reel hole inwall.
