Description

Technical Field

[0001] The utility model relates to the technical field of gears, in particular to a first-gear gear on an intermediate shaft. Background Art

[0002] Gears refer to mechanical components with gears on the wheel rim that continuously mesh to transmit motion and power. The application of gears in transmission has appeared very early. At the end of the 19th century, the principle of gear cutting was developed and special machine tools and tools for gear cutting based on this principle appeared one after another. With the development of production, the smoothness of gear operation has received attention.

[0003] According to the patent publication number CN211648964U, a first gear of an intermediate shaft is disclosed. The first gear of the intermediate shaft includes a meshing assembly and a buffer assembly, the meshing assembly includes gear teeth, an outer ring, a clamping ring and a chrome plating layer, the outer ring is sleeved on the inner ring, and the outer ring is provided with the clamping groove, the bolt passes through the outer ring through the clamping groove and is fixedly connected to the clamping ring, and the inner ring is fixedly connected to the clamping ring.

[0004] By adopting the above scheme, when the gear teeth are worn, the outer ring can be replaced, thus avoiding the need to replace the entire gear. However, the above scheme still has certain limitations: since the above device lacks an appropriate heat dissipation mechanism when designed, the temperature of the gear rises sharply when it runs at high speed or faces heavy load challenges. This excessively high temperature not only weakens the performance of the lubricating oil, but even causes it to lose fluidity, thereby causing the gear lubrication system to fail. After the lubrication fails, the friction coefficient between the gear tooth surfaces rises sharply, thereby generating more heat, forming a vicious circle. This process not only aggravates the degree of gear wear, but also significantly shortens its expected service life, causing serious impact on the overall performance and reliability of the equipment. For this reason, we provide an intermediate shaft first gear to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to make up for the deficiencies of the prior art and provide a first-gear gear for an intermediate shaft.

DETAILED DESCRIPTION

[0024] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0025] The present embodiment provides a first-gear gear on an intermediate shaft. By setting a heat dissipation mechanism 7, in actual applications, the heat dissipation mechanism 7 can effectively cope with the heat generated by the gear when it runs at high speed or faces heavy load challenges. This innovative measure not only significantly reduces the risk of lubrication failure caused by high temperature, but also avoids the problem of a sharp increase in the friction coefficient between the gear tooth surfaces caused by this, greatly extending the service life of the gear and providing users with a more reliable and lasting operating experience.

[0028] The gear is configured as two parts, the outer gear disc 1 and the inner gear disc 3, so that when the gear is worn, only the outer gear disc 1 needs to be replaced without replacing the entire gear.

[0029] An installation mechanism 4 is provided inside the installation groove 2, and a protection mechanism 5 is provided outside the outer gear disc 1. The protection mechanism 5 includes a cover 502. The outer surfaces of the outer gear disc 1, the inner gear disc 3 and the cover 502 are all provided with shaft holes 6.

[0030] The shaft hole 6 is used to mount the gear on the intermediate shaft.

[0031] A heat dissipation mechanism 7 is provided on the right side of the outer gear disc 1 .

[0032] Embodiment 2

[0033] like Figure 1-7 As shown, this embodiment further illustrates Example 1, the mounting mechanism 4 includes a group of bolts 401, the outer surface of each bolt 401 is inserted into the interior of the outer gear plate 1, the outer surface of each bolt 401 is inserted into the interior of the inner gear plate 3, and the outer surface of each bolt 401 is threadedly connected with a nut 402.

[0034] like Figure 2 As shown, the number of the bolts 401 and the number of the nuts 402 are both four.

[0035] When in use, the outer gear disc 1 and the inner gear disc 3 can be fixed together through the cooperation of the bolt 401 and the nut 402. This fixing method allows only the outer gear disc 1 to be replaced when the gear is worn, without the need for overall replacement.

[0036] The protection mechanism 5 includes a group of first threaded holes 501 , and each first threaded hole 501 is opened on the outer surface of the outer gear disc 1 .

[0037] A screw 503 is threadedly connected inside each first threaded hole 501 , and an outer surface of each screw 503 is threadedly connected to the inner surface of the cover 502 .

[0038] When in use, the cooperation among the first threaded hole 501 , the cover 502 and the screw 503 can prevent dust and impurities from entering the installation slot 2 .

[0043] The second threaded hole 705 and the threaded rod 707 allow the user to remove the heat sink 706 for cleaning or replacement. When heat accumulates in the heat sink 706, the heat dissipation in the heat sink 706 can be accelerated by turning on the cooling fan in the gear box.

[0044] When the gear is running at high speed or facing heavy load challenges, the heat it generates will gather in the heat-collecting ring 702, and after being conducted through the heat-conducting block 703 and the mounting seat 704, it will gather in the heat sink 706 and be dissipated through the heat sink 706, so as to achieve the purpose of heat dissipation of the gear.
