Description

Technical Field

[0001] This utility model relates to a coaxial speed reduction device for forced lubrication systems, belonging to the field of mechanical transmission and lubrication technology. Background Technology

[0002] In high-speed mechanical transmission systems, components such as gears and bearings generate a lot of heat and friction during operation. If lubrication is insufficient or heat dissipation is not timely, it can easily lead to excessive wear of parts, reduced efficiency, or even equipment failure.

[0003] Existing forced lubrication systems mostly rely on a single active oil injection or passive splash lubrication method, which suffers from uneven lubrication coverage, high energy consumption, or difficulty in meeting the demands of high-frequency operation. Furthermore, under high-frequency operating conditions, if the power transmission mechanism driving the lubricating oil pump operates directly at high speed, it can easily cause excessive wear of the pump and increase its structural size, hindering equipment compactness and reliability. Therefore, how to achieve miniaturization of the oil pump drive system and adapt it to high-frequency operation while ensuring adequate lubrication has become an urgent technical problem to be solved. Utility Model Content

[0004] This utility model proposes a coaxial speed reduction device for forced lubrication systems. Its purpose is to overcome the above-mentioned shortcomings of the existing technology, improve the comprehensiveness of lubrication coverage, adapt to high-frequency operation with a smaller size, and reduce oil pump wear.

[0005] The technical solution of this utility model is a coaxial reduction device for forced lubrication systems. It achieves comprehensive and efficient lubrication coverage by combining active oil injection with passive splashing. At the same time, it uses a coaxial reduction structure to drive the oil suction pump under high-frequency operation, thereby reducing the size and improving the system reliability.

[0006] Specifically, its structure includes a fan condenser, an oil filter, a high-speed flow pump, a top diversion pipe, a gearbox, and a coaxial reduction gear body. The gearbox houses a synchronous gear set, which is mounted to the gearbox sidewall via bearings. Gear oil is stored at the bottom of the gearbox, and the oil filter is connected to the sidewall of the gearbox via a pipe. The oil filter is connected to the high-speed flow pump via a pipe, and the high-speed flow pump is connected to the fan condenser via a pipe. The fan condenser is connected to the top diversion pipe located at the top of the gear oil via a pipe. The gearbox sidewall has wall-mounted channels leading to each bearing location, and the top diversion pipe connects to each wall-mounted channel. The drive end of the high-speed flow pump is connected to one shaft of the synchronous gear set via the coaxial reduction gear body. During operation, the high-speed flow pump draws the high-temperature gear oil from the bottom of the gearbox through the suction pipe to the oil filter for filtration and then sends it to the fan condenser for cooling. The cooled oil is distributed to each bearing through the top diversion pipe and wall-mounted channels, achieving cooling and heat dissipation for the high-temperature working bearings, and finally flows back to the bottom of the gearbox.

[0007] Preferably, the synchronous gear set includes a passive shaft gear set mounted on the passive shaft, a driven shaft gear set mounted on the driven shaft, and a drive shaft gear set mounted on the drive shaft. The drive shaft gear set meshes with the driven shaft gear set, and one driven shaft gear set meshes with the passive shaft gear set. The drive end of the high-speed flow pump is connected to the passive shaft through the body of the coaxial reduction device.

[0008] Preferably, the coaxial reduction gear includes coaxial reduction gears and pump drive gears. The pump drive gears are installed on the drive end of the high-speed flow pump, and the driven shaft is connected to the coaxial reduction gears via a spline. The coaxial reduction gears mesh with the high-speed flow pump. When the synchronous gear set rotates at high speed, the driven shaft drives the coaxial reduction gears to rotate via the spline connection. The coaxial reduction gears and the pump drive gears form a reduction gear set, which limits the high-speed rotation within the rated speed range of the high-speed flow pump, making it suitable for high-frequency operation and reducing the overall size.

[0009] During operation, the high-speed flow pump draws the high-temperature gear oil from the bottom of the gearbox through the suction pipe to the oil filter for filtration, and then sends it to the fan condenser for cooling. The cooled oil is distributed to each bearing through the top distribution pipe and the wall plate channel to achieve cooling and heat dissipation of the high-temperature working bearings, and finally flows back to the bottom of the gearbox.

[0010] The advantages of this utility model are: 1) Active oil injection and passive splash work together to achieve comprehensive lubrication coverage and high heat dissipation efficiency;

[0011] 2) The coaxial reduction structure can effectively prevent the oil suction pump from overspeeding, improving durability and adaptability;

[0012] 3) It has a compact structure, occupies little space, and is suitable for high-frequency, high-temperature, and heavy-load mechanical transmission systems. Attached Figure Description

Detailed Implementation

[0017] The present invention will be further described in detail below with reference to embodiments and specific implementation methods.

[0018] like Figure 1-3 As shown, the coaxial reduction gear for a forced lubrication system includes a fan condenser 1, an oil filter 2, a high-speed flow pump 3, a top diversion pipe 4, a gearbox 5, and a coaxial reduction gear body. The gearbox 5 contains a synchronous gear set 6, which is mounted to the side wall of the gearbox 5 via bearings 52. Gear oil 7 is located at the bottom of the gearbox 5. The side of the gearbox 5 containing the gear oil 7 is connected to the oil filter 2 via a pipe. The oil filter 2 is connected to the high-speed flow pump 3 via a pipe. The high-speed flow pump 3 is connected to the fan condenser 1 via a pipe. The fan condenser 1 is connected to the top diversion pipe 4 located at the top of the gear oil 7 via a pipe. The side wall of the gearbox 5 has wall plate flow channels 51 leading to the positions of each bearing 52. The top diversion pipe 4 connects to each wall plate flow channel 51. The drive end of the high-speed flow pump 3 is connected to one shaft of the synchronous gear set 6 via the coaxial reduction gear body.

[0019] Furthermore, the synchronous gear set 6 includes a passive shaft gear set 61 mounted on the passive shaft 611, a driven shaft gear set 62 mounted on the driven shaft, and a drive shaft gear set 63 mounted on the drive shaft. The drive shaft gear set 63 meshes with the driven shaft gear set 62, and one of the driven shaft gear sets 62 meshes with the passive shaft gear set 61. The drive end of the high-speed flow pump 3 is connected to the passive shaft 611 through the coaxial reduction gear body.

[0020] Furthermore, the coaxial reduction gear includes a coaxial reduction gear 8 and a pump drive gear 9. The pump drive gear 9 is installed on the drive end of the high-speed flow pump 3. The driven shaft 611 is connected to the coaxial reduction gear 8 via a spline, and the coaxial reduction gear 8 meshes with the high-speed flow pump 3. When the synchronous gear set 6 rotates at high speed, the driven shaft 611 drives the coaxial reduction gear 8 to rotate via the spline connection. The coaxial reduction gear 8 and the pump drive gear 9 form a reduction gear set, which limits the high-speed rotation within the rated speed range of the high-speed flow pump 3, making it suitable for high-frequency operation and reducing the overall size.

[0021] During operation, the high-speed flow pump 3 draws the high-temperature gear oil from the bottom of the gearbox 5 through the suction pipe to the oil filter 2 for filtration, and then sends it to the fan condenser 1 for cooling. The cooled oil is distributed to each bearing 52 through the top distribution pipe 4 and the wall plate flow channel 51 to achieve cooling and heat dissipation of the high-temperature working bearings, and finally flows back to the bottom of the gearbox 5.

[0022] According to the above process, the active oil injection mechanism installed in gearbox 5 sprays lubricating oil in a directional manner to high-speed rotating parts to achieve precise lubrication; while the eccentric blocks installed on each drive shaft rotate at high speed with the drive shaft, splashing gear oil to form oil mist, thereby achieving lubrication of parts that are difficult to spray directly.

[0023] All of the components described above are existing technologies, and those skilled in the art can use any model and existing design that can achieve their corresponding functions.

[0024] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present utility model, and these all fall within the protection scope of the present utility model.
