Accompanying drawing explanation
The accompanying drawing constituting a part of the present utility model is further appreciated by of the present utility model for providing, this
The schematic description and description of utility model is used for explaining this utility model, is not intended that this practicality new
The improper restriction of type.In the accompanying drawings:
Fig. 1 is the radial direction sectional structure schematic diagram of this utility model embodiment one.
Fig. 2 is this utility model embodiment one sectional structure schematic diagram of A-A position along Fig. 1.
Description of reference numerals: 1, rotor；2, gear ring；3, latch.
Detailed description of the invention
It should be noted that in the case of not conflicting, in embodiment in this utility model and embodiment
Feature can be mutually combined.Describe this utility model below with reference to the accompanying drawings and in conjunction with the embodiments in detail.This
" up and down ", " inside and outside " of utility model be by wind-driven generator use state time orientation on the basis of.
Embodiment one:
As depicted in figs. 1 and 2, the detachable gear wheel of the present embodiment wind-driven generator speed increasing engine includes rotor
1 and gear ring 2, gear ring 2 interference is sheathed on the outside of rotor 1, the combination between rotor 1 and gear ring 2
At least one it is provided with for transmitting the latch 3 of moment of torsion, therefore rotor 1 between rotor 1, gear ring 2 at face
And use between gear ring 2 the least magnitude of interference just can bear the axial force of gear, rotor 1 and gear ring 2 it
Between main transmit moment of torsion by latch 3, gear ring 2 can be made the thinnest, reduces material cost, Er Qieyou
Little in the magnitude of interference, reducing the interference simultaneously of gear material cost, the bending strength safety coefficient of gear is affected also
The least, do not affect the safety coefficient of gear, the present embodiment faying face between rotor and gear ring in addition
Place be provided with at least one for transmitting the latch 3 of moment of torsion between rotor 1, gear ring 2, by reasonable Arrangement insert
The size of pin 3 and quantity can ensure that the transmission of moment of torsion, safe and reliable.In the present embodiment, gear ring 2 uses by force
Spending steel that is high and that can carry out carburizing and quenching to make, rotor 1 uses common structural steel to make.
In the present embodiment, latch 3 is straight pin, for the fixed form of straight pin the most existing employing key,
Rotor 1 can be passed to, it is ensured that the reliability of moment of torsion transmission by dispersed for the moment of torsion of gear ring 2.
In the present embodiment, the faying face two ends between rotor 1 and gear ring 2 are equipped be evenly arranged multiple
Pin-and-hole, latch 3 is inserted in pin-and-hole, by multiple pin-and-holes and latch 3 can uniformly share rotor 1,
Moment of torsion between gear ring 2 so that moment of torsion transmission performance is more preferable, and stress performance is more preferable；Pin-and-hole is by being located at rotor
Half pin-and-hole on 1 outer wall, the half pin-and-hole composition being located on gear ring 2 inwall, by the structure of above-mentioned half pin-and-hole,
Be able to ensure that between rotor 1, gear ring 2 transmission moment of torsion, latch 3 respectively with rotor 1, gear ring 2
Between active force pass on the internal face of half pin-and-hole equal and dispersedly.
Seeing Fig. 1 and Fig. 2 to understand, in the present embodiment, rotor 1 is specially wheel hub.
