[0044] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0045] According to one embodiment of the present application, an oil guide plate is provided. Figure 1 to Figure 2The oil guide plate 1 includes a main body 11, and the main body 11 is provided with an oil guide port 111 suitable for communicating with the first bearing chamber 224. The main body 11 is used to wrap at least a portion of the first transmission gear 31 to guide the oil stirred up by the first transmission gear 31 to the oil guide port 111.

[0046] Specifically, the oil guide port 111 of the embodiment of the present application is arranged toward the inner wall surface of the reducer housing 2, so that the oil in the oil guide port 111 can flow down along the inner wall surface of the reducer housing 2 to the first bearing chamber 224. Thus, the main body 11 of the oil guide plate 1 wraps at least a portion of the first transmission gear 31 to guide the oil stirred up by the first transmission gear 31 to the oil guide port 111, and then flows down from the oil guide port 111 to the first bearing chamber 224, effectively achieving lubrication of the first bearing 33 in the first bearing chamber 224, and significantly improving the lubrication effect of the first bearing 33 in the first bearing chamber 224.

[0047] In one embodiment, the main body 11 includes an arc-shaped guide portion 112 , and the arc-shaped guide portion 112 wraps at least a portion of the first transmission gear 31 .

[0048] Specifically, Figure 1 and Figure 2 As shown, the arc-shaped guide portion 112 of the embodiment of the present application adopts an arc-shaped design that is the same as the outer contour of the first transmission gear 31, and wraps the first transmission gear 31. Therefore, when the first transmission gear 31 rotates, the oil in the chamber where the first transmission gear 31 is located can be stirred up, and can flow to the oil guide port 111 more quickly through the guidance of the main body 11 of the oil guide plate 1, effectively improving the oil delivery efficiency and ensuring the lubrication effect of the first bearing 33 in the first bearing chamber 224.

[0049] In addition, since the arc-shaped guide portion 112 has the same outer contour as the first transmission gear 31, when the arc-shaped guide portion 112 wraps at least a portion of the first transmission gear 31, it can also separate the oil in the chamber where the first transmission gear 31 is located from the first transmission gear 31, thereby further reducing the oil stirring loss when the first transmission gear 31 rotates.

[0050] Of course, the main body 11 can also be set to other shapes, such as U-shape or O-shape, as long as it can guide the oil stirred up by the first transmission gear 31 to the oil guide port 111. Technical personnel in this field can make a choice according to actual needs, and this application does not make any specific restrictions here.

[0051] In one embodiment, the main body 11 forms a predetermined area surrounding the first transmission gear 31 , and an oil port 113 connected to the predetermined area is formed on the oil guide plate 1 .

[0052] Specifically, Figure 1 and Figure 2 As shown, the bottom wall of the main body 11 described in the embodiment of the present application is provided with an oil through port 113, so that the oil in the chamber where the first transmission gear 31 is located can enter into the predetermined area of ​​the oil guide plate 1 surrounding the first transmission gear 31 through the oil through port 113, and then when the first transmission gear 31 rotates, more oil can be stirred up to the oil guide port, thereby further improving the lubrication effect of the first bearing 33 in the first bearing chamber 224.

[0053] Among them, the bottom wall of the arc-shaped guide portion 112 of the main body 11 described in the embodiment of the present application can further improve the efficiency of the oil in the chamber where the transmission gear is located entering the predetermined area through the oil ports 113 by opening a plurality of oil ports 113.

[0054] In addition, the embodiment of the present application can also design the area size of the oil port 113 according to the oil stirring requirement of the first transmission gear 31, so as to effectively reduce the contact surface between the first transmission gear 31 and the oil, reduce the oil stirring loss of the first transmission gear 31, and thereby improve the working efficiency of the reducer.

[0055] Of course, the oil passage 113 may also be arranged on the side wall of the oil guide plate 1 , and those skilled in the art may make a selection according to actual needs, and the present application does not make any specific limitation here.

[0056] In one embodiment, the gap between the oil passage 113 and the first transmission gear 31 is 2 mm-3 mm.

[0057] Specifically, when the gap between the oil passage 113 of the main body 11 and the first transmission gear 31 is too small, the contact area between the gear tooth surface and the oil is large, resulting in a poor splash lubrication effect of the first transmission gear 31. When the gap between the oil passage 113 of the main body 11 and the first transmission gear 31 is too large, there is more oil in the predetermined area, resulting in a large oil stirring loss of the first transmission gear 31.

[0058] Therefore, the present application sets the gap between the oil port 113 and the first transmission gear 31 to 2mm-3mm, which effectively reduces the contact area between the gear tooth surface and the oil, reduces the oil stirring loss, and further improves the lubrication efficiency of the reducer.

[0059] In one embodiment, the main body 11 is made of nylon and glass fiber.

[0060] Specifically, nylon plus glass fiber is also called glass fiber reinforced nylon. It is a composite material with glass fiber added on the basis of the original nylon material. Since nylon plus glass fiber material has good oil resistance, anti-aging performance, dimensional stability and toughness, the oil guide plate 1 made of nylon plus glass fiber can better meet the lubrication requirements of the reducer bearing and realize the transportation of the reducer oil.

[0061] Among them, common nylon plus glass fiber include PA6-GF30, PA66-GF30 and PA12-GF30.

[0062] In addition, the oil guide plate 1 made of nylon and glass fiber can further extend the service life of the reducer bearing and reduce the lubrication cost of the reducer bearing.

[0063] Of course, the oil guide plate 1 can also be made of pure nylon or steel plate. Those skilled in the art can make a choice according to actual needs, and this application does not make any specific restrictions here.

[0064] In one embodiment, the oil guide port 111 is an inclined port, which is disposed at one radial end of the arc-shaped guide portion 112 and forms an angle with the axis of the arc-shaped guide portion 112 , and the angle ranges from 10° to 45°.

[0065] Specifically, when the angle formed by the oil guide port 111 and the axis of the arc-shaped guide portion 112 is too small, the oil stirred up by the first transmission gear 31 will accumulate in the oil guide port 111 in large quantities, causing the oil guide port 111 to be blocked, and a too small inclination angle will also cause the flow rate of the oil to be too small, thereby seriously affecting the lubrication effect of the reducer bearing. When the angle formed by the oil guide port 111 and the axis of the arc-shaped guide portion 112 is too large, it will cause the area of ​​the oil guide plate 1 to be too large, thereby increasing the distance from the oil through port 113 to the oil guide port 111, making it difficult for the oil that enters the oil guide plate 1 through the oil through port 113 to reach the oil guide port 111, seriously affecting the lubrication effect of the reducer bearing. Therefore, the embodiment of the present application preferably has the angle in the range of 10°-45° to further improve the lubrication efficiency of the reducer.

[0066] According to another embodiment of the present application, a reducer is provided, which includes an oil guide plate 1, a housing 2 and a first transmission gear 31, the oil guide plate 1 is installed on the housing 2, the housing 2 is provided with an oil guide hole 225 and a first bearing chamber 224, the oil guide hole 225 respectively connects the first bearing chamber 224 and the oil guide port 111, the first transmission gear 31 is installed on the housing 2, and the main body 11 wraps at least a portion of the first transmission gear 31.

[0067] Specifically, Figures 3 to 6 As shown, the rotation of the first transmission gear 31 in the embodiment of the present application can stir up the oil in the chamber where the first transmission gear 31 is located, and the stirred oil is guided to the oil guide port 111 through the main body 11 of the oil guide plate 1, and then flows through the inner wall surface of the box body 2 to the oil guide hole 225, and then flows from the oil guide hole 225 to the first bearing chamber 224, effectively ensuring the lubrication requirements of the first bearing 33 in the first bearing chamber 224 under low-speed conditions.

[0068] Among them, when the main body 11 described in the embodiment of the present application wraps the first transmission gear 31, the coverage of the first transmission gear 31 by the oil guide plate 1 should exceed the highest liquid level after the oil is filled in the reducer, so as to reduce the contact between the first transmission gear 31 and the oil in the chamber where the first transmission gear 31 is located, thereby reducing the oil stirring loss when the first transmission gear 31 rotates.

[0069] In one embodiment, the first transmission gear 31 is supported in the first bearing chamber 224 through a first bearing 33 .

[0070] Specifically, since the first transmission gear 31 is supported in the first bearing chamber 224 by the first bearing 33, when the main body 11 of the oil guide plate 1 covers the first transmission gear 31, the oil stirred up by the first transmission gear 31 can be guided by the oil guide plate 1 to the oil guide port 111, and then flow through the inner wall surface of the box body 2 to the oil guide hole 225, and then flow from the oil guide hole 225 to the first bearing chamber 224, effectively ensuring the lubrication requirements of the first bearing 33 in the first bearing chamber 224 under low-speed conditions.

[0071] In one embodiment, the oil guide plate 1 further includes a positioning column 12 , a positioning hole is formed on the box body 2 , and the positioning column 12 cooperates with the positioning hole.

[0072] Specifically, Figure 4 and Figure 6 As shown, the oil guide plate 1 of the embodiment of the present application is provided with four positioning columns 12. The housing 2 includes a power source housing 21 and a reducer housing 22, and the positioning holes include a first positioning hole 241 and a second positioning hole 242. The power source housing 21 is provided with two first positioning holes 241, and the reducer housing 22 is provided with two second positioning holes 242.

[0073] The oil guide plate 1 is connected to the two first positioning holes 241 and the two second positioning holes 242 respectively through four positioning columns 12, so that the oil guide plate 1 can be firmly fixed on the box body 2, and the stability and reliability of the oil guide plate 1 are effectively enhanced.

[0074] Of course, the oil guide plate 1 can also be connected to the box body 2 through two, three or more positioning columns 12, or connected to the box body 2 by setting bolts, or form an integral structure with the box body 2. Technical personnel in this field can make a choice according to actual needs, and this application does not make any specific restrictions here.

[0075] It should be noted that the front mentioned in the embodiment of the present application refers to the direction of the transmission gear toward the power source housing 21, and the rear refers to the direction of the transmission gear toward the reducer housing 22.

[0076] In one embodiment, the reducer further includes a transmission structure.

[0077] Specifically, Figure 3 and Figure 5 As shown, the transmission structure of the embodiment of the present application includes a first transmission gear 31, a second transmission gear 41 and a third transmission gear 51, and the first transmission gear 31, the second transmission gear 41 and the third transmission gear 51 are meshed with each other.

[0078] The housing 2 further comprises a first bearing chamber 224, a second bearing chamber 212, a third bearing chamber 211, a fourth bearing chamber 213, a fifth bearing chamber 222 and a sixth bearing chamber 223. The first bearing chamber 224 is provided with a first bearing 33, the second bearing chamber 212 is provided with a second bearing 42, the third bearing chamber 211 is provided with a third bearing 32, the fourth bearing chamber 213 is provided with a fourth bearing 52, the fifth bearing chamber 222 is provided with a fifth bearing 43, and the sixth bearing chamber 223 is provided with a sixth bearing 53. The first bearing 33 and the third bearing 32 are used to support the first transmission gear 31, the second bearing 42 and the fifth bearing 43 are used to support the second transmission gear 41, and the fourth bearing 52 and the sixth bearing 53 are used to support the third transmission gear 51.

[0079] The embodiment of the present application supports the first transmission gear 31 , the second transmission gear 41 and the third transmission gear 51 through the first bearing 33 , the second bearing 42 , the third bearing 32 , the fourth bearing 52 , the fifth bearing 43 and the sixth bearing 53 , thereby effectively ensuring the stability and reliability of the reducer.

[0080] In one embodiment, the first transmission gear 31 is a helical gear, and the inclination direction of the oil guide port 111 is opposite to the rotation direction of the helical gear.

[0081] Specifically, Figure 2 and Figure 3 As shown, in the embodiment of the present application, the inclination direction of the oil guide port 111 is set to be opposite to the rotation direction of the bevel gear, so that when the bevel teeth of the bevel gear are inclined toward the power source housing 21, the oil guide port 111 can be inclined toward the reducer housing 22.

[0082] Furthermore, when the first transmission gear 31 rotates to stir up the oil that enters the oil guide plate 1 through the oil port 113, the bevel gear can guide the oil to the side of the oil guide port 111 facing the power source case 21, thereby effectively increasing the flow rate of the oil along the oil guide port 111 to the first shaft bearing chamber, thereby improving the lubrication efficiency of the reducer.

[0083] In one embodiment, the housing 2 includes a second bearing chamber 212 , the housing 2 forms an oil reservoir, the oil reservoir is provided with an oil hole 23 , and the second bearing chamber 212 is connected to the oil hole 23 .

[0084] Specifically, Figures 3 to 6 As shown, the embodiment of the present application can enclose the first oil chamber 214 of the power source housing 21 and the second oil chamber 221 of the reducer housing 22 into the oil reservoir by combining the power source housing 21 and the reducer housing 22. Since the oil reservoir is also provided with an oil hole 23, and the oil hole 23 is connected to the second bearing chamber 212, the present application can distribute the oil in the oil reservoir to the second bearing chamber 212, thereby achieving lubrication of the second bearing 42 in the second bearing chamber 212, and effectively ensuring the lubrication effect of the second bearing 42.

[0085] In addition, the embodiment of the present application can also change the size of the oil hole 23 of the oil reservoir and the position of the oil hole 23 in the oil reservoir during the design period. For example, by setting a plurality of oil holes 23 at different heights of the oil reservoir, different sizes of oil can be delivered to the second bearing 42 to meet the different lubrication requirements of the bearings, and the lubrication efficiency of the second bearing 42 can be improved without setting up additional driving parts.

[0086] In one embodiment, the housing 2 is further provided with an oil guide channel 215, an outlet end 2151 of the oil guide channel 215 is connected to the oil storage tank, and an inlet end 2152 of the oil guide channel 215 is located in the oil throwing direction when the first transmission gear 31 rotates in a predetermined direction.

[0087] Specifically, Figure 3 As shown, the embodiment of the present application provides the oil guide channel 215 so that when the first transmission gear 31 rotates in a predetermined direction to swing the oil, the oil can be guided to the oil storage tank through the oil guide channel 215, thereby realizing the recycling of the oil in the reducer and effectively reducing the lubrication cost of the reducer.

[0088] The predetermined direction in this embodiment refers to the rotation direction of the first transmission gear 31 when the vehicle moves forward.

[0089] In one embodiment, the reducer further includes a second transmission gear 41 and a third transmission gear 51;

[0090] The oil reservoir comprises an oil chamber overflow port 216 , and the oil in the oil reservoir can flow back to the bottom of the housing 2 along an overflow path through the oil chamber overflow port 216 , and the second transmission gear 41 and / or the third transmission gear 51 are located on the overflow path.

[0091] Specifically, Figure 3 As shown, the oil storage tank in the embodiment of the present application is provided with an oil chamber overflow port 216, so that when the oil in the oil storage tank is higher than the oil chamber overflow port 216, the oil can flow through the oil chamber overflow port 216 to the chamber where the second transmission gear 41 is located and the chamber where the third transmission gear 51 is located, and flow back to the bottom of the housing 2 along the overflow path, thereby realizing shower passive lubrication of the second transmission gear 41 and the third transmission gear 51 that are meshed and rotated at high speed, thereby further improving the lubrication effect of the second transmission gear 41 and the third transmission gear 51, improving the fatigue life of the second transmission gear 41 and the third transmission gear 51, and reducing the risk of pitting corrosion on the tooth surfaces of the second transmission gear 41 and the third transmission gear 51.

[0092] The overflow path of this embodiment refers to the path of the oil in the oil reservoir passing through the chamber where the second transmission gear 41 is located and / or the chamber where the third transmission gear 51 is located.
