Gear wheel

Technical Field

The utility model belongs to the technical field of the gear, especially, relate to a gear.

Background

The gear is a part which is frequently used in mechanical transmission, adopts high-quality high-strength alloy steel, is subjected to surface carburizing and hardening treatment, and has strong bearing capacity and durability. However, in the high-speed rotating and sealing structure, in the process of long-time high-speed operation of the gear, the temperature of the whole gear is finally increased due to the fact that the meshed teeth are heated due to long-time friction, the existing gear is poor in heat dissipation effect and affected by high temperature, the service life of the existing gear is shortened, the working precision is reduced, and the use requirement of existing high-precision equipment cannot be met.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a solve prior art's weak point, and provide a gear with good radiating effect.

The utility model aims at solving the problems by the following technical scheme:

a gear comprises a fluted disc and a plurality of meshing teeth arranged on the outer edge of the fluted disc, wherein meshing grooves are arranged between the meshing teeth at intervals, and the gear is characterized in that: the surface of the fluted disc is provided with a circular groove, a circular heat dissipation base with a shape matched with the shape is arranged in the circular groove, the surface of the heat dissipation base is uniformly provided with a plurality of heat dissipation fins, and the heat dissipation fins are provided with heat dissipation holes.

Based on the structure, the arrangement of the radiating fins increases the radiating area of the gear, has a better radiating effect, can effectively reduce the working temperature of the fluted disc and the meshing teeth, and ensures the service life and the working precision of the gear; the arrangement of the heat dissipation holes further increases the heat dissipation area, reduces the resistance of the heat dissipation fins, and further improves the performance of the gear.

Preferably, the fin is the arc design, the louvre orientation is unanimous with the direction of rotation of fluted disc.

Preferably, fin and heat dissipation base integrated into one piece.

Preferably, heat dissipation base and fluted disc can be dismantled the connection, seted up threaded through hole along the axial on the heat dissipation base, set up threaded blind hole with threaded through hole matched with position on the annular groove, still including with threaded through hole, threaded blind hole matched with screw, the heat dissipation base passes through the fix with screw in annular groove.

Preferably, ring shape recess the central axis and the fluted disc the central axis coincides mutually.

Compared with the prior art the utility model has the following characteristics and beneficial effect:

1. the arrangement of the radiating fins increases the radiating area of the gear, has a good radiating effect, can effectively reduce the working temperature of the fluted disc and the meshing teeth, and ensures the service life and the working precision of the gear.

2. The radiating fins are designed in an arc shape, the orientation of the radiating holes is consistent with the rotating direction of the fluted disc, the resistance of the radiating fins to the rotation of the gear is effectively reduced, and the working performance of the gear is improved.

3. The connection can be dismantled to heat dissipation base and fluted disc, can process gear and radiating part respectively, has reduced the processing degree of difficulty, and when radiating part or gear received the damage, only need change damaged part can, reduced the loss.
