Description

Technical Field

[0001] The utility model relates to the technical field of lubrication devices, in particular to a combined gear box lubrication device. Background Art

[0002] Gearboxes are widely used, for example, in wind turbines. Gearboxes are an important mechanical component that is widely used in wind turbines. Their main function is to transmit the power generated by the wind rotor to the generator and make it obtain the corresponding speed.

[0003] Liquid lubricant is indispensable in the operation of the gearbox. Liquid lubricant can lubricate the meshing between the gears inside the gearbox, reduce the friction between the gears, and reduce the wear of the gears during rotation, thereby extending the service life of the gearbox. When the gearbox lacks liquid lubricant, the friction between the teeth increases, causing the temperature generated by the gearbox to increase significantly. The existing lubrication device requires the staff to operate the lubrication device when they find that the gearbox lacks liquid lubricant to achieve the lubrication function of the gears.

[0004] In addition, the existing lubrication device cannot control the supply amount of liquid lubricating oil when lubricating the gearbox, and often the liquid lubricating oil is supplied too much or too little, resulting in waste of liquid lubricating oil and insufficient lubrication. Therefore, a combined gearbox lubrication device is proposed to solve the above problems. Utility Model Content

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] Reference Figure 1-4 A combined gearbox lubrication device includes an oil tank 1 and a spray box 2 fixedly connected to the bottom end of the oil tank 1. The oil tank 1 is filled with liquid lubricating oil. The spray box 2 is installed on the top end of the gearbox. The bottom end of the spray box 2 and the top end of the gearbox are provided with aligned spray ports 201. The arrangement of the spray ports 201 allows the atomized liquid lubricating oil sprayed from the spray box 2 to enter the interior of the gearbox.

[0023] The side wall of the spray box 2 is rotatably provided with a reciprocating screw shaft 8, and the outer side wall of the spray box 2 is installed with a forward and reverse motor 5. The output end of the forward and reverse motor 5 is fixedly connected to the reciprocating screw shaft 8. The surface of the reciprocating screw shaft 8 is threadedly connected with a nut block, and one end of the nut block is fixedly connected to a circular outer box 7;

[0024] It should be noted that the forward and reverse motor 5 drives the reciprocating screw shaft 8 to rotate intermittently forward and reverse, so that the nut block moves back and forth along the reciprocating screw shaft 8, and then drives the circular outer box 7 to move back and forth, so that the sprayed liquid lubricating oil contacts the gears inside the gear box.

[0025] A conveying roller 11 is provided for rotation inside the circular outer box 7. A circumferentially distributed oil storage tank is provided on the surface of the conveying roller 11. A counterweight block 12 is slidingly provided on the inside of the oil storage tank. The top of the circular outer box 7 is fixedly connected to the bottom end of the oil tank 1 through a telescopic hose 6. Furthermore, a plurality of atomization holes 701 are provided at the bottom end of the circular outer box 7. A reduction gear 9 is fixedly connected to the center of the conveying roller 11 through a rotating shaft. An intermittent motor 10 is installed on the outer wall of the circular outer box 7. The output end of the intermittent motor 10 is fixedly connected to a driving gear 13 that meshes with the reduction gear 9.

[0026] It should be noted that when the gearbox needs to be replenished with liquid lubricating oil, the intermittent motor 10 drives the conveying roller 11 to rotate intermittently one circle, so that the oil storage tanks at various locations pass through the atomization hole 701 in turn, thereby realizing the automatic replenishment function of the liquid lubricating oil inside the gearbox;

[0027] It should be noted that: when the oil storage tank moves to the pipe mouth of the telescopic hose 6, the liquid lubricating oil will automatically enter the oil storage tank until the oil storage tank is full. When the oil storage tank moves to the atomization hole 701, the liquid lubricating oil will be sprayed out through the atomization hole 701. At this time, the counterweight block 12 on the inside of the oil storage tank will press down the liquid lubricating oil, increasing the spraying pressure of the liquid lubricating oil, so that the liquid lubricating oil is quickly atomized and sprayed out through the atomization hole 701, realizing the atomization function of the liquid lubricating oil. The contact area between the atomized lubricating oil and the gears inside the gearbox is significantly increased, ensuring the uniformity of the gear contact of the lubricating oil, while increasing the spraying range of the lubricating oil and improving the lubricating oil replenishment efficiency.

[0028] Furthermore, an oil filling port is provided at the top of the oil tank 1 , a sealing plug 3 is provided in the oil filling port, an alarm 4 is installed at the top of the oil tank 1 , and a guide block 14 is fixedly connected to the inner wall of the oil tank 1 .

[0029] It should be noted that the setting of the oil filling port facilitates the replenishment of lubricating oil into the oil tank 1, the setting of the alarm 4 can be used to remind the staff that the gear box is short of lubricating oil, and the setting of the guide block 14 allows the liquid lubricating oil inside the oil tank 1 to gather at the pipe mouth of the telescopic hose 6, ensuring that the liquid lubricating oil inside the oil tank 1 can be completely discharged.

[0030] Furthermore, the top end of the circular outer box 7 is fixedly connected to a limit plate, and the top end of the limit plate is slidably connected to the inner top end of the spray box 2 via a slider.

[0031] It should be noted that the setting of the limiting plate can limit the circular outer box 7 and ensure that the nut block can move horizontally along the reciprocating screw shaft 8.

[0032] Furthermore, a temperature sensor is installed inside the gear box, and a controller is installed on the top of the oil tank 1. The controller establishes an information transmission connection with the temperature sensor and the alarm 4.

[0033] It should be noted that the temperature sensor can sense the temperature value inside the gear box. When the temperature value inside the gear box rises significantly, the temperature sensor will feedback to the controller. The controller controls the alarm 4 to sound an alarm to remind the staff, and at the same time controls the intermittent motor 10 to automatically replenish the liquid lubricating oil to the gear box.

[0034] It is worth noting that: after the lubricating oil is replenished inside the gear box, if the alarm 4 continues to alarm after a period of time, it means that the temperature inside the gear box is abnormal, which is not caused by lack of lubricating oil and requires further inspection by staff.

[0035] When the present invention is in use, when the temperature inside the gear box rises significantly, the temperature sensor senses the temperature abnormality and feeds back to the controller. The controller controls the alarm 4 to work and sounds an alarm to remind the staff. At the same time, the intermittent motor 10 is controlled to work. The intermittent motor 10 drives the conveying roller 11 to rotate intermittently one circle (the oil storage tank can play a quantitative function for the liquid lubricating oil. The conveying roller 11 rotates one circle to quantitatively control the replenishment amount of the liquid lubricating oil). The oil storage tanks at various locations pass through the atomizing hole 701 in turn. When the oil storage tank moves, When the liquid lubricating oil reaches the atomizing hole 701, it will be sprayed out through the atomizing hole 701. At this time, the counterweight 12 inside the oil storage tank will press down the liquid lubricating oil, increasing the spraying pressure of the liquid lubricating oil, so that the liquid lubricating oil is quickly atomized and sprayed out through the atomizing hole 701, realizing the atomization function of the liquid lubricating oil. The contact area between the atomized lubricating oil and the gears inside the gearbox is significantly increased, ensuring the uniformity of the gear contact of the lubricating oil and the lubricating oil. At the same time, the spraying range of the lubricating oil is increased, the lubricating oil replenishment efficiency is improved, and the lubricating oil replenishment function of the gearbox is automatically realized.

[0036] At the same time, the controller controls the forward and reverse rotation of the motor 5, and the nut block drives the circular outer box 7 to move back and forth, further expanding the range of lubricating oil replenishment, making it easier to replenish lubricating oil to various gears inside the gear box.

[0037] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
