The trapezoidal shape in section of slot is additionally provided with reinforcing rib between the support ring body and blade, the width of reinforcing rib from support ring body toward
Direction blade is gradually reduced.
By using above-mentioned technical proposal, rotor body includes support ring body, and support ring body is equipped with location hole and edge
The boss of location hole side setting, supports the side of ring body to be additionally provided with several blades, blade groove is formed between two adjacent blades,
It sets using the above structure, it is simple in structure, it is easy to process, and in order to improve heat dissipation effect, it is several by being equipped on boss
Heat-radiating ring-groove, and each heat-radiating ring-groove circular array is arranged in the side of location hole improves heat dissipation area and heat dissipation
Uniformity coefficient then ensures good practical function, and is equipped between boss and support ring body and contradicts inclined-plane, it is ensured that peace
Convenient degree during dress, is equipped with oil storage tank between each blade and boss, the groove width of oil storage tank is gradual from boss toward direction blade
Reduce, and the trapezoidal shape in section of oil storage tank, by the oil storage tank of setting, improve lubricant effect, it is ensured that good practicability,
And reinforcing rib is additionally provided between support ring body and blade, then the structure further improved between support ring body and blade is strong
Degree, and the width of reinforcing rib is gradually reduced from support ring body toward direction blade, then further ensures stress point and concentrate on branch
On pushing out ring body, and then ensure good structural strength and stability.
The utility model is further arranged to：The bottom of the support ring body is additionally provided with several limit holes, and each limit hole is in
Annular array is set to the side of location hole, and the arc shape of limit hole.
By using above-mentioned technical proposal, the bottom of ring body is supported to be additionally provided with several limit holes, each limit hole battle array in a ring
Row are set to the side of location hole, are set by using above structure, it is ensured that the convenient degree of installation, and the arc of limit hole
Shape, positioning and adjusting during convenient installation improve the stability of installation.
The utility model is further arranged to：The notch bore of the heat-radiating ring-groove is gradually subtracted from one end toward another extreme direction
It is small.
By using above-mentioned technical proposal, the notch bore of heat-radiating ring-groove is gradually reduced from one end toward another extreme direction, is led to
It crosses and sets heat-radiating ring-groove using the above structure so that when rotor rotates, flowing of the air-flow in rotor surface is improved, and then
Improve heat dissipation effect.
Description of the drawings
Fig. 1 is a kind of positive structure diagram of VVT rotor embodiments of the utility model.
