Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of heat dissipation structure of speed reducer, and particularly relates to a speed reducer shell. BACKGROUND

[0002] The conventional speed reducer shell relies on surface natural heat dissipation. When the heat generated inside cannot be dissipated in time, the temperature of lubricating oil is increased. The lubricating oil is prone to oxidation reaction in a high-temperature environment to generate impurities such as oil sludge and paint film, so that the oil deteriorates and loses lubricating performance, thereby the lubricating oil inside the mechanical part needs to be replaced more frequently, and the maintenance cost is increased. Therefore, further improvement is needed. CONTENT OF THE UTILITY MODEL

[0003] In order to solve the above problems, the present application provides a speed reducer shell.

[0004] The present application provides a speed reducer shell, which adopts the following technical scheme:

[0005] The speed reducer shell comprises a shell and a heat dissipation mechanism arranged on the shell. The heat dissipation mechanism comprises a heat dissipation air duct arranged in the shell and a fan arranged on the shell for flowing air outside into the shell. The shell is provided with an air inlet and an air outlet at opposite ends. The heat dissipation air duct is arranged in a spiral shape around the axial direction of the shell.

[0006] By adopting the above technical scheme, the heat dissipation air duct is arranged in the shell, and the fan is used to introduce air outside into the shell through the air inlet, so that the air flow can flow along the spiral path, the turbulence and stagnation of the air flow in the air duct are reduced, the flow efficiency of the air flow is improved, and the heat exchange time between the cold air and the hot air can be increased to improve the heat dissipation effect. At the same time, the design of the air inlet and the air outlet ensures the smooth flow of the air flow, further promotes the discharge of heat, effectively reduces the temperature of the lubricating oil, reduces the deterioration problem of the lubricating oil due to high-temperature oxidation, prolongs the service life of the lubricating oil, and reduces the maintenance cost.

[0007] Preferably, a plurality of turbulence blocks are arranged on the inner wall of the heat dissipation air duct and are arranged at intervals along the axial direction of the heat dissipation air duct.

[0008] By adopting the above technical scheme, a plurality of turbulence blocks arranged at intervals along the axial direction are arranged on the inner wall of the heat dissipation air duct, which can effectively increase the turbulence degree of the air flow in the air duct, destroy the laminar boundary layer of the air flow, and thus improve the heat exchange efficiency. This structure design enables the heat to be more uniformly and quickly conducted from the inside of the speed reducer to the external environment, reduces the possibility of oxidation reaction of the lubricating oil due to high temperature to generate impurities, prolongs the service life of the lubricating oil, and reduces the maintenance cost. In addition, the arrangement of the turbulence blocks can also reduce the dead angle of the air flow in the air duct, and further improve the heat dissipation performance.

[0009] Preferably, two adjacent turbulence blocks are connected to each other by a connecting rib, and the connecting rib is fixedly connected to the inner wall of the heat dissipation air duct.

[0010] By adopting the above technical scheme, the connecting rib can enhance the structural stability between the two adjacent turbulence blocks, reduce the possibility of loosening or falling off of the turbulence block under the impact of high-speed airflow, and thus ensure the long-term stability of the airflow guiding effect in the heat dissipation air duct. In addition, the fixed connection of the connecting rib and the inner wall of the heat dissipation air duct further improves the strength of the overall structure, so that the heat dissipation mechanism can still maintain good heat dissipation performance under complex working conditions.

[0011] Preferably, two adjacent turbulence blocks are arranged in a staggered manner.

[0012] By adopting the above technical scheme, the staggered arrangement of the turbulence blocks disturbs the flow direction of the airflow, making the airflow more turbulent, thereby destroying the stability of the boundary layer and further enhancing the heat exchange effect and improving the overall heat dissipation performance.

[0013] Preferably, the heat dissipation mechanism comprises a heat-conducting inner layer arranged in the shell and a heat dissipation member arranged between the heat-conducting inner layer and the shell, and the heat dissipation air duct is arranged on the inner surface of the heat-conducting inner layer away from the shell.

[0014] By adopting the above technical scheme, the heat in the reducer shell can be quickly absorbed by the heat-conducting inner layer and transferred to the heat dissipation member, and then efficiently exchanged with the external air through the heat dissipation air duct, thereby significantly improving the heat dissipation efficiency. By arranging the heat dissipation member between the heat-conducting inner layer and the shell and arranging the heat dissipation air duct on the inner surface of the heat-conducting inner layer away from the shell, the heat conduction path is further optimized, and the heat dissipation uniformity and efficiency are improved.

[0015] Preferably, the inner circumferential wall of the heat-conducting inner layer is provided with two heat-conducting plates arranged in a spiral shape around the axis thereof, and the heat dissipation air duct is formed between the two heat-conducting plates, and the heat-conducting plates are connected to the heat-conducting inner layer.

[0016] Preferably, the heat dissipation member is a heat exchange pipe, the heat exchange pipe is filled with a cooling medium, the shell is provided with a conveying member for conveying the cooling medium, the heat exchange pipe is also arranged in a spiral shape around the axis of the heat-conducting inner layer, a first spring is arranged between two adjacent spiral segments of the heat exchange pipe, and the shell is provided with a pushing assembly for pushing the first spring to vibrate.

[0017] By adopting the technical scheme, the heat exchange pipe is filled with the cooling medium, and the circulation flow of the cooling medium is realized by cooperating with the conveying member, so that the heat generated in the speed reducer can be effectively taken away, the heat dissipation efficiency is significantly improved, the possibility of deterioration of the lubricating oil due to high-temperature oxidation is reduced, the service life of the lubricating oil is prolonged, and the maintenance cost is reduced.

[0018] Preferably, the pushing assembly comprises a push plate coaxially sleeved on the heat-conducting inner layer and a pushing member for moving the push plate towards the heat exchange pipe, the push plate is fixedly connected with a second spring, and an end of the second spring away from the push plate is connected to the heat exchange pipe.

[0019] By adopting the technical scheme, the push plate and the pushing member are arranged to push the cooling medium to flow in the heat exchange pipe, the heat exchange effect is enhanced, and the heat dissipation efficiency is further improved.

[0020] In summary, the utility model has the following beneficial effects:

[0021] 1. By arranging the heat dissipation air duct and the fan in the shell, the air circulation in the shell can be effectively enhanced, the heat dissipation is accelerated, the temperature of the lubricating oil is reduced, the risk of oxidation reaction of the oil due to high temperature is reduced, and the service life of the lubricating oil is prolonged.

[0022] 2. The heat dissipation effect in the shell is further improved by arranging the heat dissipation member. BRIEF DESCRIPTION OF DRAWINGS
