Description

Technical Field

[0001] The utility model relates to the technical field of speed reducer cooling, in particular to a cooling shell of a helical planetary speed reducer. Background Art

[0002] Helical planetary reducer is a kind of reduction gear widely used in various fields that require precision mechanical transmission. Compared with spur planetary reducer, helical planetary reducer has many advantages, such as wide transmission ratio range, high efficiency, high precision, etc. The main feature of helical planetary reducer is that its transmission gear adopts helical gear design. Compared with the parallel axis gear of spur planetary reducer, the gear of helical planetary reducer can mesh better, reduce shock and vibration, and improve transmission stability and precision.

[0003] During the operation of the helical planetary reducer, there is friction between the gears and bearings, which will cause heat generation. In addition, if the helical planetary reducer is overloaded or improperly lubricated, it will also cause more heat to be generated. In the helical planetary reducer, the middle position of the equipment is more closed than the outer position, and the air circulation is not smooth, resulting in the heat not being effectively removed. Due to the premise that the heat dissipation in the middle of the equipment is slow, the heat in the middle of the equipment may continue to accumulate during use, causing the temperature to rise without timely heat dissipation. The increase in temperature will cause the viscosity of the lubricating oil to decrease, resulting in a decrease in the lubrication effect and an increase in friction and wear of the transmission system. This will reduce the transmission efficiency of the helical planetary reducer, affect its normal operation, and then accelerate the aging and damage of the components in the equipment and reduce its service life. Thermal expansion may also cause the size of the components to change, causing the gap to become larger, further increasing the risk of wear and failure. Utility Model Content

[0008] Preferably, an output shaft is provided on one side of the planetary gear, and the output shaft passes through the housing.

[0010] Preferably, a heat sink is provided in the placement cavity for quickly transferring heat to the external environment.

[0015] Preferably, the second liquid outlet and the first liquid outlet are both connected to an external cooling box.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] Cooling water enters from the middle through cooling pipe 1 and cooling pipe 2 to cool the two ends of the reducer, ensuring that the heat in the middle of the equipment will not accumulate excessively. The flow of cooling water can be fully utilized to improve the heat dissipation efficiency of the equipment. Cooling water enters from the middle, which can quickly take away the heat, avoiding the problem of heat accumulation in the middle of the equipment, which will cause the equipment temperature to rise and may cause failures or reducer performance degradation. The heat in the middle can be taken away in time, keeping the temperature of the equipment within a reasonable range, reducing the risk of equipment failure, and ensuring the normal operation of the reducer. It can effectively reduce the operating temperature of the equipment, reduce the impact of thermal stress on components, extend the service life of the equipment, reduce the impact of thermal expansion and contraction on the reducer, and improve the operating stability and accuracy of the equipment.

[0018] By using cooling tube 1 and cooling tube 2 in conjunction with the heat sink, a better heat dissipation effect can be provided. Heat can be quickly transferred to the heat sink, and the heat is transferred to cooling tube 1 and cooling tube 2, so that the heat inside the helical planetary reducer is absorbed and the heat is discharged from the device. This can improve the heat conduction efficiency and allow the heat to be dissipated from the helical planetary reducer more quickly. The heat sink usually has a large heat dissipation surface. By using it in conjunction with cooling tube 1 and cooling tube 2, the heat dissipation surface area is increased. By increasing the heat dissipation area, the heat dissipation efficiency can be improved, and the heat diffusion and conduction on the heat sink can be accelerated, so that the heat can be taken away more quickly.

[0030] The cooling tube 1 503 and the cooling tube 2 504 are arranged in a spiral shape, and the placement cavity 501 is arranged between the outer surface of the housing 1 and the installation cavity 2. Among them, the cooling tube 1 503 and the cooling tube 2 504 are arranged in a spiral shape, and the spiral cooling tube can increase the heat dissipation area, thereby improving the heat dissipation efficiency. The spiral cooling tube can guide the air flow, enhance the heat exchange efficiency between the air and the cooling tube, and further improve the heat dissipation effect. The spiral cooling tube can effectively reduce the fluid resistance, ensure that the fluid flows smoothly in the tube, and reduce the impact and wear of the fluid on the tube wall.

[0031] It should be noted that excessive accumulation of heat will cause thermal stress on the parts of the equipment, causing fatigue, damage or even premature failure of the parts. Cooling through cooling pipe 1 503 and cooling pipe 2 504 can effectively reduce the operating temperature of the equipment, reduce the impact of thermal stress on the parts, and extend the service life of the equipment.

[0032] An output shaft 3 is provided on one side of the planetary gear 4, and the output shaft 3 passes through the housing 1. The housing 1 is made of a high thermal conductivity material, which is used to quickly extract the heat when the reducer is running. The high thermal conductivity material can quickly transfer heat and reduce the loss of heat during the transfer process, thereby improving the heat dissipation efficiency of the reducer. Through effective heat dissipation, it is possible to avoid problems such as thermal deformation and thermal expansion of the reducer due to overheating during operation, improve its stability and reliability, and the high thermal conductivity material can effectively reduce the temperature of the reducer, reduce material fatigue and aging caused by high temperature, and thus extend the service life of the reducer.

[0033] A heat sink 507 is provided in the placement cavity 501, which is used to quickly transfer heat to the external environment. A liquid inlet 502 is provided in the middle of the outer surface of the shell 1. The liquid inlet 502 is connected to the cooling pipe 1 503 and the cooling pipe 2 504, and the liquid inlet 502 is externally connected to a cooling water pump. A liquid outlet 1 505 is provided on the top of the shell 1, and the liquid outlet 1 505 is connected to the cooling pipe 1 503. A base 5 is provided at the bottom of the shell 1, and a liquid outlet 2 506 is connected to the bottom of the shell 1, and the liquid outlet 2 506 passes through the base 5, and the liquid outlet 2 506 is connected to the cooling pipe 2 504.

[0034] Specifically, the coolant in the cooling box is transported into cooling tube 1 and cooling tube 2 504 through the liquid inlet 502, the heat sink 507 absorbs the heat and conducts it to cooling tube 1 503 and cooling tube 2 504, and the heat is dissipated from the middle of the equipment to both ends of the equipment. The coolant that has absorbed the heat returns to the cooling box through the liquid outlet 1 505 and the liquid outlet 2 506, avoiding excessive heat accumulation in the middle of the equipment, keeping the temperature of the equipment within a reasonable range, reducing the risk of equipment failure, and ensuring the normal operation of the reducer, which can effectively reduce the operating temperature of the equipment and reduce the impact of thermal stress on components.

[0035] It is worth mentioning that the cooperation between cooling tube 1 503 and cooling tube 2 504 and heat sink 507 can provide a better heat dissipation effect, and the heat can be quickly transferred to heat sink 507, and the heat is transferred to cooling tube 1 503 and cooling tube 2 504, so as to absorb the heat inside the helical planetary reducer and discharge the heat out of the device. In this way, the heat conduction efficiency can be improved, so that the heat can be dissipated from the helical planetary reducer more quickly.
