Abstract
The utility model discloses a cooling device in a gear box, which belongs to the field of gear boxes and comprises a fan arranged on a transmission shaft in the gear box. The utility model aims to solve the problem of overhigh temperature in the gear box and further improve the heat dissipation effect.
Description
Technical Field
The utility model relates to the field of gear boxes, in particular to a cooling device in a gear box.
Background
The gear box comprises a shell and a plurality of gears arranged in the shell, the gears are arranged on the transmission shaft, and the gear box can be used for speed changing, direction changing and the like. The gearbox generates a large amount of heat during operation, and for this reason, in the prior art, a ventilation cap is arranged on the housing of the gearbox to discharge hot air, or in order to improve the heat dissipation effect, a fan is arranged on the housing of the gearbox to strengthen the air flow. However, since a large number of gears and the like are arranged in the gear box, the components can have a certain blocking effect on the airflow, thereby influencing the heat dissipation effect.
Disclosure of utility model
The utility model aims to solve the problems and provide a cooling device in a gear box, which can solve the problem of overhigh temperature in the gear box and further improve the heat dissipation effect.
In order to achieve the above purpose, the technical scheme adopted by the utility model is that the cooling device in the gear box comprises a fan arranged on a transmission shaft in the gear box, and the fan is directly arranged on the transmission shaft, so that on the basis of no need of an additional power source, air flow is directly generated in the gear box along with rotation of the transmission shaft, and then the cooling device is matched with a ventilation cap on a shell, and the problem of overhigh temperature in the gear box can be well solved.
Furthermore, because the internal space of the gear box is smaller, in order to facilitate the disassembly and assembly of the fan, the fan is composed of fan blade parts arranged in an annular array, and when the fan is installed, only the fan blade parts are spliced together and are hooped on the transmission shaft in a hoop mode.
Further, in order to facilitate disassembly and assembly of the fan, two adjacent fan blade portions are connected through bolts.
The utility model has the beneficial effects that: the power source for the rotation of the fan comes from the transmission shaft in the gear box, so that the phenomenon of poor air circulation in the gear box can be improved on the premise of not needing additional power supply, the heat dissipation effect is improved, and the problem that the temperature of the gear box is too high can be effectively solved by matching with the prior art such as a ventilation cap.

Detailed Description
In order that those skilled in the art may better understand the technical solutions of the present utility model, the following detailed description of the present utility model with reference to the accompanying drawings is provided for exemplary and explanatory purposes only and should not be construed as limiting the scope of the present utility model.
Embodiment 1, as shown in fig. 1-2, the structure of this embodiment is: the cooling device in the gear box comprises a fan 2 arranged on a transmission shaft 1 in the gear box, the rotation axis of the fan 2 is coaxial with the transmission shaft, and the blades of the fan can be fixed on the transmission shaft in a welding mode or the like or are fixed on the transmission shaft by bolts.
The specific heat dissipation process comprises the following steps: when the gear box starts to work, the transmission shaft 1 in the gear box starts to rotate so as to drive the fan 2 to rotate, thereby generating air flow in the gear box so as to bring heat out of the shell, and then matching with the heat dissipation fan, the ventilation cap and the like on the shell, so that the problem of overhigh temperature in the gear box is jointly solved.
In embodiment 2, as shown in fig. 3, other structures and heat dissipation processes of the present embodiment refer to embodiment 1, but in order to realize quick assembly and disassembly of the fan in this embodiment, the fan 2 is composed of fan blade portions 201 disposed in an annular array, the fan blade portions 201 include arc-shaped supports and fan blades, the supports of the fan blade portions 201 are assembled and then enclose into a circle adapted to the transmission shaft 1, in this embodiment, two fan blade portions 201 are exemplified, the supports are semicircular, and the two supports can be fixed together by adopting a bolt, a connecting shaft, and other modes, and in this embodiment, bolts are adopted.
It should be noted that, in this document, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
The principles and embodiments of the present utility model have been described herein with reference to specific examples, the description of which is intended only to facilitate an understanding of the method of the present utility model and its core ideas. The foregoing is merely illustrative of the preferred embodiments of the utility model, and it is noted that there is virtually no limit to the specific structure which may be imposed by those skilled in the art without departing from the spirit of the utility model, and that modifications, adaptations, or variations of the foregoing features may be combined in a suitable manner; such modifications, variations and combinations, or the direct application of the inventive concepts and aspects to other applications without modification, are contemplated as falling within the scope of the present utility model.
