Background

The gear is a common mechanical transmission part, transmits motion and power through continuous meshing of the gear on the wheel rim, and is an important power transmission mechanism in equipment such as automobiles or precision machinery. Along with the development of production, the smoothness and wear resistance of gear operation are more and more emphasized. The existing gears are standard parts, have no special design in the aspects of stability and strength, and can not meet the use requirements more and more. Therefore, a new technical solution should be provided to solve the above problems.

Disclosure of Invention

The utility model aims at: aiming at the defects, the gear with the improved structure is reasonable in structure and good in using effect.

In order to achieve the above object, the utility model adopts the following technical scheme:

the utility model provides an improve gear of structure, includes the gear main part, tooth has evenly been seted up on the periphery of gear main part, and is adjacent the alveolus has been seted up between the tooth, the central point of gear main part puts and has seted up the shaft hole, the outside in shaft hole is equipped with annular strengthening rib, annular strengthening rib's outside is equipped with the crack control circle, and the inner wall in shaft hole is equipped with a plurality of constant head tank along its circumferencial direction upward interval, is equipped with the boss between the adjacent constant head tank, the boss passes through the splice bar and links to each other with annular strengthening rib, heat conduction circle is installed to the inboard of gear main part, the inner circle of heat conduction circle.

The further technical scheme is as follows:

the heat conduction ring and the gear body are bonded.

A plurality of arc-shaped grooves are formed in the gear body.

And a damping hole is formed between adjacent arc-shaped grooves on the gear body, and damping materials are filled in the damping hole.

The strengthening rib is provided with six, and the strengthening rib equidistance distributes in the inboard of heat conduction circle.

Because of above-mentioned technical scheme's application, compared with the prior art, the utility model have following advantage:

1. the utility model discloses a gear, it is rational in infrastructure, the annular strengthening rib of setting has improved the atress intensity of crack control circle, and then has improved the atress intensity of gear, has prolonged the life of gear.

2. The utility model discloses a heat conduction circle is installed to the gear in the inboard of gear main part, and the inner circle of heat conduction circle is inlayed and is had the strengthening rib, and the heat that the heat conduction circle can disperse the gear rapidly and produce avoids high temperature heat to be detained on the gear for a long time and causes the influence to gear work.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Figure 2 is a schematic structural diagram of an embodiment of the present invention.

In the above drawings: 1. gear main part, 2, tooth, 3, alveolus, 4, shaft hole, 5, annular strengthening rib, 6, crack control circle, 7, constant head tank, 8, boss, 9, splice bar, 10, heat conduction circle, 11, strengthening rib, 12, arc wall, 13, shock attenuation hole, 14, shock-absorbing material.

Detailed Description

The invention will be further described with reference to the following drawings and examples:

the first embodiment is as follows:

as shown in fig. 1, as the first embodiment of the utility model, a gear of improved structure, including gear main body 1, tooth 2 has evenly been seted up on gear main body 1's the periphery, and is adjacent tooth groove 3 has been seted up between tooth 2, gear main body 1's central point puts and has seted up shaft hole 4, shaft hole 4's outside is equipped with annular strengthening rib 5, annular strengthening rib 5's outside is equipped with crack control circle 6, and shaft hole 4's inner wall is equipped with a plurality of constant head tank 7 along its circumferencial direction at the interval, is equipped with boss 8 between the adjacent constant head tank 7, boss 8 links to each other with annular strengthening rib 5 through splice bar 9, heat conduction circle 10 is installed to gear main body 1's inboard, heat conduction circle 10's inner circle is inlayed and is had strengthening rib 11.

Preferably, as the utility model discloses a second embodiment, this embodiment is the further improvement to embodiment one, be provided with a plurality of arc wall 12 on the gear main part 1, be equipped with shock attenuation hole 13 between the adjacent arc wall 12, shock attenuation hole 13 intussuseption is filled with shock-absorbing material 14.
