Description

Cooling device for gear box

Technical Field

The utility model belongs to the technical field of the gear box cooler, more specifically relate to a cooling device for gear box.

Background

With the continuous advancement of science and technology and the rapid development of society, gear boxes are widely used in various industries. The existing gear box needs lubricating oil for lubrication in work, the lubricating oil mainly lubricates the meshing part of a gear box bearing and a gear, pressure oil lubrication and splash lubrication are generally adopted, and heat generated in the running process of the bearing and the gear is taken away. Therefore, the lubricating oil needs to exchange heat with the outside.

At present, the heat exchange between the lubricating oil and the outside is generally carried out by an external cooler. The external cooler is arranged outside the gear box, so that the occupied space is large, and the heat exchange efficiency is low; and an oil pump and corresponding matched oil pipes and oil circuit accessories are required to be added to effectively circulate lubricating oil, and then the lubricating oil can reach the cooler for heat exchange, so that the manufacturing cost is greatly increased.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a cooling device for gear box, whole volume is less, and the heat transfer is fast, and the structure sets up ingeniously, simple to operate, and the cost is also lower, has solved the problem that above-mentioned prior art exists.

The utility model discloses a cooling device for gear box, including first body, second body and apron, the end of first body is first import and first export respectively, and the end of second body is second import and second export respectively, and first import, first export, second import and second export are all installed in the through-hole on the apron, and first body is type structure, and the second body is U type spiral body, and the first half of first body is located to second body cover.

In some embodiments, the joints of the first inlet, the first outlet, the second inlet and the second outlet with the through holes on the cover plate are all provided with sealing rings.

In some embodiments, the seal ring is made of a rubber material.

In some embodiments, the first tube and the second tube are both stainless steel.

In some embodiments, the outer walls of the first and second tubular bodies are provided with an oxidation-resistant coating.

The utility model provides a cooling device for gear box's beneficial effect lies in:

1. the utility model provides a cooling device for a gear box, which can synchronously cool double tube bodies;

2. the first pipe body of the utility model is of a convex structure, the second pipe body is a U-shaped spiral pipe body, and the second pipe body is sleeved on the upper half part of the first pipe body; the whole volume is less, and the heat transfer is fast, and the structure sets up ingeniously, simple to operate, and the cost is also lower.

3. The utility model provides a first body and second body are stainless steel material, and the outer wall is equipped with anti oxidation coating for the sound construction of first body and second body, oxidation resistance is good, and whole cooling device's live time is longer.

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

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1, the utility model discloses a cooling device for gear box, including first body, second body and apron. The end of the first pipe body is respectively provided with a first inlet and a first outlet, and the end of the second pipe body is respectively provided with a second inlet and a second outlet. First import, first export, second import and second export are all installed in the through-hole on the apron, and just first import, first export, second import and second export all are equipped with the sealing washer with the through-hole junction on the apron. The sealing ring is made of rubber materials, so that the sealing performance is good.

The first pipe body is of a convex structure, the second pipe body is a U-shaped spiral pipe body, and the second pipe body is sleeved on the upper half portion of the first pipe body. The whole volume is less, and the heat transfer is fast, and the structure sets up ingeniously, simple to operate, and the cost is also lower. The first pipe body and the second pipe body are made of stainless steel materials. The outer walls of the first pipe body and the second pipe body are provided with anti-oxidation coatings.

The utility model discloses when concrete implementation, set up the mounting hole on the gear box, install cooling device in the gear box, first import, first export, second import and second export are passed through the connector and are connected with the cooling pump, and the cooling pump is placed in the box that is equipped with the coolant liquid. The cooling liquid enters the first pipe body from the first inlet and flows out from the first outlet; the cooling fluid also enters the second tube from the second inlet and exits the second outlet. In the circulation process, the first pipe body and the second pipe body are in contact with lubricating oil in the gear box, heat of the lubricating oil in the gear box is conducted to cooling liquid in the first pipe body and the second pipe body through heat conduction, and the cooling liquid is taken out of a box body which is filled with the cooling liquid and is arranged outside the gear box. The first pipe body is of a convex structure, the second pipe body is of a U-shaped spiral pipe body, the contact area of the first pipe body and lubricating oil is larger than that of a cooling device with a simple U-shaped structure, and heat exchange is faster; the second pipe body is sleeved on the upper half part of the first pipe body; the whole volume is less, and the heat transfer is fast, and the structure sets up ingeniously, simple to operate, and the cost is also lower. When concrete implementation, first body and second body are stainless steel material, and the outer wall is equipped with anti oxidation coating for the sound construction of first body and second body, oxidation resistance is good, and whole cooling device's live time is longer.

The cooling device for the gear box provided by the utility model is a double-tube synchronous cooling device; the whole volume is less, and the heat transfer is fast, and the structure sets up ingeniously, simple to operate, and the cost is also lower.

The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, similar modifications and improvements can be made without departing from the inventive concept, and these should also be considered as within the protection scope of the present invention.
