[0043] An embodiment of the present application provides a lubricating gear assembly, comprising:

[0044] The liquid supply component 100 is provided with a liquid inlet hole 110a and a liquid outlet hole 110b connected to the liquid inlet hole 110a, and the liquid inlet hole 110a is connected to an external device for supplying lubricant;

[0045] An aluminum gear 110 is rotatably mounted on the liquid supply assembly 100 . The aluminum gear 110 is provided with a first flow channel 110 a .

[0046] The soft gear 120 is provided on the liquid supply assembly 100 and is coaxially arranged with the aluminum gear 110;

[0047] Among them, the aluminum gear 110 and the soft gear 120 are both engaged with the driving gear of the wind generator set. The driving gear of the wind generator set rotates to drive the aluminum gear 110 and the soft gear 120 to rotate around the liquid supply component 100, so that the liquid flowing out of the first flow channel 110a can coat the driving gear of the wind generator set.

[0048] Please refer to Figure 1-Figure 5 In this embodiment, the lubricant enters the liquid inlet hole 110a of the liquid supply component 100 through an external supply device, the lubricant flows into the liquid supply component 100 from the liquid inlet hole 110a, and enters the first flow channel 110a of the aluminum gear 110 through the liquid outlet hole 110b.

[0049] The driving gear of the wind turbine generator set rotates, driving the aluminum gear 110 and the soft gear 120 to rotate around the liquid supply assembly 100 .

[0050] The lubricant flows out through the first flow channel 110a of the aluminum gear 110 and is applied to the driving gear, thereby ensuring lubrication between the gears and reducing wear.

[0051] Automatic lubrication of the wind turbine driving gear is realized without manual operation, which greatly improves the maintenance efficiency.

[0052] Ensure that the lubricant can be evenly applied to each lubrication point of the drive gear to reduce gear wear and extend gear life.

[0053] The combination of the aluminum gear 110 and the soft gear 120 avoids the complicated process of machining the integral aluminum block of the traditional lubricated gear, reduces the weight of the component, and facilitates transportation and assembly.

[0054] The aluminum gear 110 is a spur gear, and in other embodiments, it may be other gears, such as a helical gear, etc. The aluminum gear 110 is made of aluminum material.

[0055] The soft gear 120 has substantially the same shape as the aluminum gear 110 . The soft gear 120 is made of a flexible material, such as rubber, plastic, etc. In this embodiment, the soft gear 120 is made of a rubber material.

[0056] The liquid supply assembly 100 is provided with a liquid inlet 110a and a liquid outlet 110b connected to the liquid inlet 110a. The liquid inlet 110a is connected to an external device for supplying lubricant, so that the lubricant can enter the liquid supply assembly 100 through the liquid inlet 110a.

[0057] The liquid inlet hole 110a is connected to an external device for supplying lubricant, ensuring that the lubricant can be continuously supplied to the lubrication system.

[0058] The lubricant is grease.

[0059] A first flow channel 110 a is provided in the aluminum gear 110 , one end of which is connected to the liquid outlet 110 b and the other end of which is connected to the outside. Lubricant can flow from the liquid supply assembly 100 to the outside of the aluminum gear 110 through the channel.

[0060] The soft gear 120 is installed on the liquid supply assembly 100 and is coaxially arranged with the aluminum gear 110. The soft gear 120 is coaxially arranged with the aluminum gear 110 to ensure that they can rotate synchronously.

[0061] The aluminum gear 110 and the soft gear 120 are both meshed with the driving gear of the wind turbine generator set. The rotation of the driving gear drives the aluminum gear 110 and the soft gear 120 to rotate together.

[0062] When the driving gear of the wind turbine generator set rotates, the aluminum gear 110 and the soft gear 120 are driven to rotate around the liquid supply assembly 100, thereby realizing the transmission and application of the lubricating liquid.

[0063] In at least one embodiment of the present application, the aluminum gear 110 is located between two adjacent soft gears 120 .

[0064] Please refer to Figure 1-Figure 5 In this embodiment, the lubricant enters the liquid supply component 100 through an external device, enters the interior of the liquid supply component 100 through the liquid inlet hole 110a, and enters the first flow channel 110a of the aluminum gear 110 from the liquid outlet hole 110b of the liquid supply component 100, and is transmitted along the first flow channel 110a.

[0065] The driving gear of the wind turbine generator set rotates, driving the aluminum gear 110 and the soft gear 120 to rotate around the liquid supply assembly 100. The lubricant flows out through the first flow channel 110a of the aluminum gear 110 and is smeared on the driving gear.

[0066] The lubricant also flows to the junction between the soft gear 120 and the aluminum gear 110 to ensure that the gear surfaces are fully lubricated.

[0067] The aluminum gear 110 is located between the two soft gears 120, which can help the lubricant to be more evenly distributed on the gear surface, reduce the lubrication dead angle, and ensure the lubrication effect of all parts of the gear.

[0068] Due to its flexibility, the soft gear 120 can absorb part of the impact force during the meshing process, reduce the direct friction between the aluminum gear 110 and the driving gear, and reduce the wear of the gear.

[0069] In at least one embodiment of the present application, the aluminum gear 110 has a plurality of meshing teeth 111, each of the meshing teeth 111 is provided with the first flow channel 110a, a positioning hole 110b is provided at the geometric center of the aluminum gear 110, the liquid supply assembly 100 passes through the positioning hole 110b, one end of the first flow channel 110a is provided on the meshing teeth 111, and the other end is connected to the positioning hole 110b.

[0070] Please refer to Figure 1-Figure 5 In this embodiment, the lubricant enters the liquid supply assembly 100 through an external supply device and enters the interior of the liquid supply assembly 100 through the liquid inlet hole 110a.

[0071] The lubricant flows from the liquid outlet hole 110 b of the liquid supply assembly 100 into the positioning hole 110 b of the aluminum gear 110 , and the lubricant enters the first flow channel 110 a of each meshing tooth 111 through the positioning hole 110 b .

[0072] The driving gear of the wind turbine generator set rotates, driving the aluminum gear 110 and the soft gear 120 to rotate around the liquid supply assembly 100 .

[0073] During the rotation of the aluminum gear 110 , the lubricant flows out from the meshing teeth 111 through the first flow channel 110 a and is coated on the driving gear.

[0074] A first flow channel 110a is provided on each meshing tooth 111 to ensure that the lubricant can be evenly applied to each tooth surface of the driving gear to avoid local wear.

[0075] The lubricant is efficiently transmitted through the positioning holes 110b and the plurality of first flow channels 110a, and can quickly cover the gear surface, thereby improving lubrication efficiency.

[0076] Evenly distributed lubricant can effectively reduce friction and wear between gears and extend the service life of gears.

[0077] In at least one embodiment of the present application, the meshing tooth 111 has two meshing arc surfaces 111 a arranged opposite to each other, each of the meshing arc surfaces 111 a is provided with the first flow channel 110 a , and the meshing arc surfaces 111 a are used to mesh with the driving gear of the wind turbine generator set.

[0078] Please refer to Figure 1-Figure 5 In this embodiment, the lubricant enters the liquid supply assembly 100 through an external device and enters the interior of the liquid supply assembly 100 through the liquid inlet hole 110a.

[0079] The lubricant flows from the liquid outlet hole 110 b of the liquid supply assembly 100 into the positioning hole 110 b of the aluminum gear 110 , and further enters the first flow channel 110 a of each meshing tooth 111 in sequence through the positioning hole 110 b .

[0080] The driving gear of the wind turbine generator set rotates, driving the aluminum gear 110 and the soft gear 120 to rotate around the liquid supply assembly 100 .

[0081] During the rotation of the aluminum gear 110 , the lubricant flows out from each meshing arc surface 111 a through the first flow channel 110 a and is coated on the tooth surface of the driving gear.

[0082] The lubricant is evenly applied to the meshing surface of the gear through the first flow channel 110a of the meshing arc surface 111a, thereby ensuring the lubrication effect during the meshing process.

[0083] Since each meshing arc surface 111 a is provided with the first flow channel 110 a , the lubricant can be evenly applied to the meshing surface of the gear to avoid local insufficient lubrication.

[0084] Evenly distributed lubricant effectively reduces friction and wear between gears and extends the service life of the gears.

[0085] The first flow channel 110a directly delivers the lubricant to the meshing arc surface 111a, thereby optimizing the lubrication path and reducing the waste of lubricant.

[0086] The meshing arc surface 111 a is the tooth surface of the gear tooth groove.

[0087] In at least one embodiment of the present application, the meshing tooth 111 also has a tooth top surface 111b, and the tooth top surface 111b is provided with a second flow channel 111c connected to the first flow channel 110a, and the second flow channel 111c is opened in a direction perpendicular to the tooth top surface 111b, and one end of the second flow channel 111c is connected to the outside, and the other end passes through the meshing tooth 111 and extends into the positioning hole 110b and is connected to the positioning hole 110b, and the liquid inlet hole 110a is connected to the positioning hole 110b, and the liquid inlet hole 110a conveys lubricant to the first flow channel 110a through the second flow channel 111c.

[0088] In at least one embodiment of the present application, the lubricating gear assembly further comprises:

[0089] The blocking ball 130 is arranged in the second flow channel 111c. The blocking ball 130 is located at one end of the second flow channel 111c close to the tooth top surface 111b, so that the lubricant enters the first flow channel 110a after passing through the second flow channel 111c and flows out through the first flow channel 110a.

[0090] Please refer to Figure 1-Figure 5 In this embodiment, the lubricant enters the liquid supply assembly 100 through an external supply device and enters the interior of the liquid supply assembly 100 through the liquid inlet hole 110a.

[0091] The lubricant flows from the liquid inlet hole 110 a into the positioning hole 110 b of the aluminum gear 110 , and enters the second flow channel 111 c of each meshing tooth 111 through the positioning hole 110 b .

[0092] The lubricant enters the first flow passage 110a through the second flow passage 111c.

[0093] The driving gear of the wind turbine generator set rotates, driving the aluminum gear 110 and the soft gear 120 to rotate around the liquid supply assembly 100 .

[0094] During the gear rotation, the lubricant flows out through the first flow channels 110a on both sides of the meshing teeth 111 and is coated on the driving gear.

[0095] The blocking ball 130 controls the flow direction of the lubricant, ensuring that the lubricant enters the first flow channel 110 a after passing through the second flow channel 111 c, and is smeared from the tooth top surface 111 b to the meshing arc surface 111 a of the meshing tooth 111 .

[0096] The second flow channel 111c facilitates the processing of the lubrication channel of the aluminum gear 110, so as to process a lubricant flow channel connected to the positioning hole 110b, and then process the first flow channel 110a, so as to facilitate the processing of the aluminum gear 110. Through the control of the blocking ball 130, it is ensured that the lubricant accurately flows into the first flow channel 110a on both sides of the meshing tooth 111, and the lubricant can fully cover the meshing surface of the aluminum gear 110, providing more effective lubrication.

[0097] The blocking ball 130 is spherical.

[0098] In at least one embodiment of the present application, in the opening direction of the second flow channel 111 c , the projection area of ​​the blocking ball 130 completely blocks the second flow channel 111 c .

[0099] Please refer to Figure 1-Figure 5 In this embodiment, when the lubricant passes through the second flow channel 111c, the complete shielding effect of the blocking ball 130 allows the lubricant to flow out only through the first flow channel 110a to reach the meshing arc surface 111a, and finally be smeared on the arc surface of the meshing tooth 111, providing lubrication for the driving gear of the wind turbine generator set.

[0100] The utilization rate of lubricant is improved, so that the lubricant can effectively reach the parts that need lubrication.

[0101] Through the control of the blocking balls 130 , the lubricant can be transmitted to the key parts of the meshing teeth 111 more quickly, thereby improving the lubrication efficiency.

[0102] In at least one embodiment of the present application, the tooth top circle diameter of the aluminum gear 110 is denoted as a, and the tooth top circle diameter of the soft gear 120 is denoted as b, satisfying the relationship: b>a, so that the lubricant flowing out of the first flow channel 110a flows to the connection between the soft gear 120 and the aluminum gear 110 to apply to the lubrication points of the driving gear of the wind turbine.

[0103] Please refer to Figure 1-Figure 5 In this embodiment, the tooth addendum diameter of the aluminum gear 110 refers to the diameter of the tooth addendum circle of the aluminum gear 110, which is denoted as a.

[0104] The tooth addendum diameter of the soft gear 120 refers to the diameter of the tooth addendum of the soft gear 120 , which is denoted by b.

[0105] The tooth top circle diameter b of the soft gear 120 is larger than the tooth top circle diameter a of the aluminum gear 110 . Since the soft gear 120 is larger than the aluminum gear 110 , the lubricant flowing out of the first flow channel 110 a naturally flows to the connection between the soft gear 120 and the aluminum gear 110 .

[0106] During the rotation process, the lubricant flows to the joint between the soft gear 120 and the aluminum gear 110, and further flows to the lubrication point of the driving gear of the wind turbine generator set for effective lubrication.

[0107] The lubricant enters the liquid supply assembly 100 through an external device and enters the interior of the liquid supply assembly 100 through the liquid inlet hole 110 a .

[0108] The lubricant flows from the liquid inlet hole 110a into the positioning hole 110b of the aluminum gear 110, is transmitted to the tooth top surface 111b through the first flow channel 110a, and flows out.

[0109] After the lubricant flows out of the first flow channel 110 a of the aluminum gear 110 , the lubricant naturally flows to the connection between the soft gear 120 and the aluminum gear 110 because the diameter b of the soft gear 120 is larger than the diameter a of the aluminum gear 110 .

[0110] The lubricant continues to flow to the lubrication points of the wind turbine drive gears, smearing on the meshing surfaces of the gears to provide effective lubrication.

[0111] Since the diameter of the soft gear 120 is larger than that of the aluminum gear 110 , the lubricant naturally flows to the connection between the soft gear 120 and the aluminum gear 110 , thereby achieving more effective optimization of the lubrication path.

[0112] The lubricant can flow accurately to the lubrication point of the driving gear, which improves the utilization efficiency of the lubricant and reduces the waste of lubricant.

[0113] The lubricant can be evenly distributed on the meshing surface of the gears through an optimized path, ensuring that each lubrication point is fully lubricated and reducing local wear.

[0114] In at least one embodiment of the present application, the liquid supply assembly 100 includes:

[0115] The connecting shaft 101 has a third flow channel 101a formed therein, and the peripheral surface of the connecting shaft 101 is provided with the liquid outlet 110b. The connecting shaft 101 passes through the aluminum gear 110 and the soft gear 120;

[0116] The connecting member 102 is disposed at one end of the connecting shaft 101 . The connecting member 102 is provided with a liquid inlet hole 110 a . The liquid inlet hole 110 a is connected to the liquid outlet hole 110 b .

[0117] Please refer to Figure 1-Figure 5 In this embodiment, the lubricant enters the liquid inlet hole 110a of the connecting piece 102 through an external supply device, and the connecting piece 102 is connected to one end of the connecting shaft 101.

[0118] The lubricant enters the third flow channel 101 a inside the connecting shaft 101 through the liquid inlet hole 110 a of the connecting piece 102 , flows along the third flow channel 101 a , and flows out through the liquid outlet holes 110 b on the peripheral surface of the connecting shaft 101 .

[0119] After the lubricant flows out from the liquid outlet 110b of the connecting shaft 101, it flows into the second flow channel 111c of the aluminum gear 110. The lubricant reaches the meshing arc surface 111a through the first flow channel 110a, completing the lubrication and ensuring that the lubricant can be efficiently transmitted and distributed to the key lubrication points of each gear component.

[0120] The driving gear of the wind generator set drives the aluminum gear 110 and the soft gear 120 to move around the axis of the connecting shaft 101, so that the aluminum gear 110 and the soft gear 120 apply lubricant to the driving gear of the wind generator set.

[0121] It should be noted that the connecting shaft 101 is roughly shaft-shaped and hollow inside. The connecting piece 102 is a joint, one end of which is connected to an external liquid supply device and the other end is connected to the third flow channel 101a of the connecting shaft 101.

[0122] In at least one embodiment of the present application, there are multiple liquid outlet holes 110 b, and each of the aluminum gears 110 corresponds to one liquid outlet hole 110 b;

[0123] When the driving gear of the wind turbine generator set drives the aluminum gear 110 to rotate around the connecting shaft 101 , the liquid outlet 110 b injects lubricant into the first flow channel 110 a on each of the meshing teeth 111 in turn.

[0124] Please refer to Figure 1-Figure 5 In this embodiment, the lubricant enters the liquid inlet hole 110 a of the connecting piece 102 through an external device, and then enters the third flow channel 101 a inside the connecting shaft 101 .

[0125] The lubricant flows out through the multiple liquid outlet holes 110 b on the connecting shaft 101 , and each liquid outlet hole 110 b corresponds to an aluminum gear 110 , thereby ensuring that the lubricant can be evenly distributed to each aluminum gear 110 .

[0126] The driving gear of the wind turbine generator set drives the aluminum gear 110 and the soft gear 120 to rotate around the connecting shaft 101. As the aluminum gear 110 and the soft gear 120 rotate, the liquid outlet 110b injects lubricant into the first flow channel 110a on each meshing tooth 111 in turn.

[0127] The lubricant enters the first flow channel 110a through the liquid outlet 110b, and the lubricant is transmitted and flows out along the first flow channel 110a, and is smeared on the meshing surface of the gear to achieve effective lubrication.

[0128] Each aluminum gear 110 can be supplied with lubricant, ensuring that the lubricant can be accurately injected into the first flow channel 110a of each meshing tooth 111 to achieve precise lubrication.

[0129] As the aluminum gear 110 rotates, the liquid outlet 110b injects lubricant into each meshing tooth 111 in turn, and the lubricant can be distributed on the gear surface in a timely and uniform manner, thereby improving the lubrication efficiency.

[0130] Accurately control the injection position and amount of lubricant to avoid lubricant waste and improve the economy and environmental protection of the lubrication system.

[0131] The above is only an implementation method of the present application. It should be pointed out that a person skilled in the art can make improvements without departing from the inventive concept of the present application, but these improvements are within the scope of protection of the present application.
