Description

Technical Field

[0001] This utility model relates to the field of gearbox technology, specifically to a transmission gearbox with a coupling. Background Technology

[0002] Gearboxes have a wide range of applications, such as in wind turbine generators. They are a crucial mechanical component widely used in wind turbine generators. Their main function is to transmit the power generated by the wind turbine under wind force to the generator, enabling it to achieve the corresponding rotational speed.

[0003] Most existing gears are either unidirectional or bidirectional. Unidirectional transmission can increase transmission speed and is therefore widely used. Bidirectional transmission, compared to unidirectional transmission, makes full use of the power source and reduces energy consumption. However, most existing bidirectional transmission gearboxes are bidirectional once they start running and cannot switch between unidirectional and bidirectional transmission. This limits the use of the gearbox and reduces its applicability.

[0004] As disclosed in CN214367638U, a transmission gearbox uses a rotating adjustment handle to rotate a connecting plate from a horizontal to a vertical position, thus changing its height. When the connecting plate rotates, a slider pushes the fixed frame and the moving frame upwards. Simultaneously, the slider slides inside the fixed frame, and the moving frame moves upwards, causing the worm gear to move upwards. When the worm gear moves upwards, it engages with the turbine gear. The rotation of the worm gear drives the turbine gear, which in turn drives the second output shaft, achieving bidirectional drive. This allows for switching between unidirectional and bidirectional drive, improving the gearbox's applicability and energy efficiency. Furthermore, the number of outputs can be adjusted according to actual needs, avoiding power waste.

[0005] However, this device is inconvenient to lubricate the gear transmission inside the gearbox during use, which leads to wear between the gears and affects the transmission efficiency of the gears.

[0006] Therefore, we urgently need to provide a transmission gearbox with a coupling. Utility Model Content

[0007] The purpose of this invention is to provide a transmission gearbox with a coupling to solve the problem mentioned in the background art that it is inconvenient to lubricate the gear transmission in the gearbox during use, which leads to wear between gears and affects the transmission efficiency of the gears.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a transmission gearbox with a coupling, comprising a gearbox, a gear transmission mechanism, a transmission shaft, a coupling, a rotating shaft, and an output shaft.

[0013] Preferably, the sleeve has a cavity inside. The end of the inlet pipe away from the pump body is connected to the sleeve, and the end of the outlet pipe away from the sleeve is connected to the cold water tank. When the lubricating oil flows through the outlet pipe, the pump body is started, so that the cold water in the cold water tank flows into the cavity of the sleeve through the inlet pipe and exchanges heat with the lubricating oil in the outlet pipe to cool the lubricating oil. At the same time, the cold water flows back into the cold water tank along the outlet pipe to realize the subsequent recycling of the cold water.

At the same time, the lubricating oil carries away the heat inside the gearbox, cooling the gear transmission mechanism. Subsequently, the oil flows out through the oil outlet pipe, is filtered by a filter screen, and then flows back into the oil tank along the connecting pipe, thus achieving both lubrication and cooling of the gear transmission mechanism and improving gear transmission efficiency.

The semiconductor cooling chip 905 cools the cold water below partition 901, thereby realizing water recycling.

[0031] During use, when lubrication of the gear transmission mechanism 2 inside the gearbox 1 is required, the oil pump 702 is started to send the lubricating oil in the oil tank 701 into the gearbox 1 through the oil inlet pipe 703 to lubricate the gear transmission mechanism 2. At the same time, the lubricating oil carries away the heat inside the gearbox 1, cooling the gear transmission mechanism 2. Subsequently, the oil flows out through the oil outlet pipe 704. Simultaneously, the pump body 803 is started to draw out the cold water in the cold water tank 802, allowing it to enter the cavity opened in the sleeve 801 along the water inlet pipe 804. Inside, as cold water flows along the cavity, it exchanges heat with the oil in the oil outlet pipe 704 to cool the oil. After cooling, the oil is filtered by the filter screen 707 and flows back into the oil tank 701 along the connecting pipe 705. At the same time, the cold water in the sleeve 801 flows into the lower layer of the cold water tank 802 along the water outlet pipe 805. Then, the cold water in the lower layer of the cold water tank 802 is cooled by the semiconductor cooling chip 905. Then, the pump body 902 is started to pump the lower layer of cold water to the upper layer of the partition 901 to realize the recycling of cold water.
