[0024] The present application will be further described below in combination with the drawings and specific embodiments. It should be noted that the description of these embodiments is used to help understand the present application, but does not constitute a limitation on the present application. The specific structural and functional details disclosed in this paper are only used to describe the example embodiments of the present application. However, the present application can be embodied in many alternative forms, and should not be understood as being limited in the embodiments described herein.

[0025] Spline drive is a mechanical transmission method that transmits torque and rotational motion through spline shaft 501 and its mating spline sleeve. The spline teeth can provide a larger contact area, enabling the transmission of higher torque. The spline teeth shape and dimensional accuracy are high, ensuring the accuracy and reliability of the transmission. Moreover, the spline can slide axially, which allows for some axial adjustment of the spline connection. The spline tooth design makes assembly and disassembly easier, facilitating maintenance and replacement.

[0026] Spline drive is widely used in various fields such as automobiles, machinery, aerospace, etc. For example, spline is often used in automobile gearboxes, drive shafts, machine tool spindles, etc. to achieve power transmission. According to the shape and tooth profile, spline can be divided into rectangular spline, involute spline, triangular spline, etc.

[0027] Spline shaft 501 is a mechanical transmission component that synchronously rotates with the corresponding spline on the rotating part through the longitudinal keyway on the shaft. In some cases, spline shaft 501 can also slide longitudinally on the shaft, such as gear shifting in a gearbox.

[0028] The working principle of spline drive mainly depends on the precise fit between spline shaft 501 and its mating components. During design, parameters such as spline specification, module, tooth number, pressure angle, etc. need to be considered to ensure the efficiency and reliability of the transmission. Involute spline is a common type of spline, with a tooth profile that is a gradual opening line. It can generate radial force under load, achieving automatic centering and making each tooth bear force evenly, thereby improving strength and lifespan.

[0029] In practical applications, the damage morphology and wear mechanism of spline drive are also factors that need to be considered during design. To improve the lifespan and load capacity of spline drive, some measures can be taken, such as controlling the offset angle of internal and external spline coupling, improving lubrication, tooth surface hardening, increasing tooth number, adding plating layer on the surface, reasonably selecting tooth side clearance and tooth length modification, etc.

[0030] Lubrication of spline drive is crucial for maintaining its high efficiency, stability, and long-term operation.

[0031] Lubrication not only reduces friction and wear but also helps dissipate heat, preventing performance degradation caused by overheating. Good lubrication environment is particularly important for precision mechanical components such as ball spline.

[0032] According to the usage conditions and working environment of spline drive, appropriate lubricants should be selected. Commonly used lubricants include lubricating oil and lubricating grease. Lubricating oil is suitable for high temperature or high speed environments, while lubricating grease is suitable for heavy load or vibration environments. The replenishment time of lubricant should be based on the usage conditions. Generally, lubricating grease should be replenished or replaced every 100 km or 6 months to 1 year of operation.

[0033] By regularly checking the movement state and noise of the ball spline, potential problems can be found in time and timely intervention and maintenance can be carried out. Through the above measures, the spline transmission system can maintain good performance and prolong the service life under various working conditions.

[0034] As Figure 1 shown, Figure 1 a cross-sectional view of the lubrication replenishment system in operation is provided for the embodiments of the present application, a lubrication replenishment system of a transmission pair, the lubrication replenishment system comprising a main body 100 and a replenishment 200, wherein:

[0035] As Figure 1 shown, the main body 100 is used for detachable connection on the spline shaft 501, and the first operation groove 101 is formed on the side wall of the main body 100 towards the spline shaft 501, and when the main body 100 is fixed on the spline shaft 501, the connection part of the spline shaft 501 and the spline inner gear ring 502 is communicated with the first operation groove 101.

[0036] The main body 100 is used for cooperation with the spline shaft 501 to realize detachable connection, and the main body 100 can be made of steel or alloy to ensure durability and reliability under high load conditions, and the first operation groove 101 is formed on the side wall of the main body 100 to accommodate oil for lubrication, and is communicated with the connection part between the spline shaft 501 and the spline inner gear ring 502 to ensure that the oil in the first operation groove 101 can fill the spline area between the spline shaft 501 and the spline inner gear ring 502. The shape and size of the first operation groove 101 are designed according to the specifications of the spline shaft 501 and the inner gear ring to ensure correct cooperation and connection between them.

[0037] As Figure 1 shown, the main body 100 is used for detachable connection on the spline shaft 501, which is convenient for maintenance and replacement, reduces downtime, improves the flexibility and adaptability of the system. In addition, it can also reduce the stress concentration and damage that may be caused by fixed connection.

[0038] In order to ensure the effective lubrication between the spline shaft 501 and the inner gear ring and prevent contaminants from entering, the oil added in the first operation groove 101 is convenient for cleaning and lubricating the connection part between the spline shaft 501 and the inner gear ring.

[0039] As Figure 1 shown, the replenishment 200 is connected with the main body 100, and one end of the replenishment 200 is communicated with the first operation groove 101, and the other end is used for connecting an oil source for pressurized oil to enter the first operation groove 101.

[0040] The connection of the supplementary part 200 to the main part 100 enables the transfer of the working oil from the oil source into the first working groove 101 and the pressurized injection of the oil through the first working groove 101.

[0041] The supplementary part 200 and the main part 100 are matched by corresponding structures to ensure that they can be accurately and stably connected together. This connection can be achieved through threads, clamping grooves, pins or other mechanical connection methods, aiming to ensure that the supplementary part 200 will not fall off due to vibration or pressure during the operation of the equipment.

[0042] As shown in Figure 1 The first working groove 101 is used to connect the connection area of the spline shaft 501 and the spline inner ring 502. When the main part 100 is fixed on the spline shaft 501, the first working groove 101 ensures the connectivity of the connection area between the spline shaft 501 and the inner ring to the oil source.

[0043] One end of the supplementary part 200 is connected to the first working groove 101 so that the oil can flow smoothly into the working groove from this end, and the other end is designed with an interface to connect the oil source, which can be a valve, a quick connector or other types of connection devices, used to control the inflow of oil.

[0044] Through the pressurized operation of the supplementary part 200, the oil can enter the supplementary part 200 from the oil source and finally flow into the first working groove 101. This design allows effective lubrication and cooling of the connection area between the spline shaft 501 and the inner ring, and also can assist the connection or maintain the stability of the connection through pressure, achieving efficient connection between the spline shaft 501 and the spline inner ring 502, while ensuring the need for lubrication and cooling, improving the reliability and life of the entire system.

[0045] In an optional embodiment, the working principle of the lubrication supplement system of the transmission pair in the application is that the lubrication supplement system comprises a main body 100 and a supplement 200, the main body 100 is used for detachable connection on the spline shaft 501, a first working groove 101 is formed on the side wall of the main body 100 towards the spline shaft 501, when the main body 100 is fixed on the spline shaft 501, the connection part of the spline shaft 501 and the spline inner ring gear 502 is communicated with the first working groove 101, the supplement 200 is connected with the main body 100, one end of the supplement 200 is communicated with the first working groove 101, and the other end is used for connecting an oil source for pressurized oil entering the first working groove 101. In actual lubrication supplement operation, the main body 100 is connected on the spline shaft 501, at this time, the main body 100 is in contact with the spline inner ring gear 502 at one end of the spline shaft 501, and the first working groove 101 is communicated with the connection part of the spline shaft 501 and the spline inner ring gear 502, then the supplement 200 is operated to control the oil for lubrication to enter the first working groove 101. Under the premise that the volume of the first working groove 101 is limited, the oil is continuously controlled to the connection part of the spline shaft 501 and the spline inner ring gear 502, forming the operation of lubrication supplement. The whole operation process does not need to disassemble and assemble the original transmission pair system, and the lubrication supplement system is installed based on the spline shaft 501, which is flexible and reliable in operation, can quickly perform the lubrication supplement operation on the spline of the transmission pair system, reduces the operation intensity and difficulty of the operation personnel, and improves the operation efficiency.

[0046] As shown in Figure 1 In an optional embodiment, a conveying member 300 is arranged between the supplement 200 and the main body 100, the conveying member 300 is internally provided with a channel for oil flow, the flexibility of the arrangement area of the supplement 200 is improved, the main body 100 and the supplement 200 are separately arranged through the conveying member 300, and the reliability of oil flow is maintained.

[0047] As shown in Figure 1 In an optional embodiment, a connecting hole 103 is formed on the main body 100, one end of the connecting hole 103 is communicated to the first working groove 101, and one end of the conveying member 300 is detachably connected on the connecting hole 103, so that the channel is communicated with the first working groove 101.

[0048] Specifically, the connecting hole 103 for connecting one end of the conveying member 300 is arranged on the main body 100, and one end of the connecting hole 103 extends to the first working groove 101, so that the communication reliability is maintained.

[0049] As shown in Figure 1As shown, in an optional embodiment, the connecting hole 103 is provided with an internal thread, and one end of the conveying member 300 is provided with a rotatable connecting ring 301, and the connecting ring 301 is provided with an external thread that cooperates with the internal thread.

[0050] The threaded connection between the conveyor 300 and the main body 100 facilitates the assembly and disassembly of the conveyor 300, improving operational efficiency and connection reliability. The connecting ring 301 is rotatable. During the rotation of the connecting ring 301 relative to the main body 100, the threaded connection with the main body 100 is completed, and the relative positional relationship between the conveyor 300 and the main body 100 is constrained, preventing the conveyor from coming off.

[0051] like Figure 1 As shown, in an optional embodiment, the lubrication replenishment system further includes a connector 400, one end of which passes through the main body 100 and is connected to the spline shaft 501, and the other end is used to press against the main body 100.

[0052] Specifically, a detachable connection is achieved between the main body 100 and the spline shaft 501 through a connector 400. After the connector 400 passes through the main body 100, it can be fixed on the spline shaft 501. Specifically, a connection position needs to be pre-machined on the spline shaft 501 to facilitate the precise installation of the connector 400.

[0053] like Figure 1 As shown, in an optional embodiment, the connector 400 is a bolt, and the bolt connection screw hole can be pre-machined on the end face of the spline shaft 501.

[0054] like Figure 1 As shown, in an optional embodiment, a boss 102 is provided in the first working groove 101. When the main body 100 is fixed on the spline shaft 501, the boss 102 can abut against the end face of the spline shaft 501. After the main body 100 is connected and fixed to the spline shaft 501, the boss 102 on the main body 100 abuts against the end face of the spline shaft 501. At the same time, the boss 102 maintains the effective depth of the first working groove 101. During the process of the connecting member 400 continuously fixing the main body 100, the boss 102 can provide stable support and improve the overall structural strength of the main body 100. It should be noted that the connecting member 400 passes through the boss 102 and connects with the spline shaft 501 to improve the connection stability.

[0055] In an optional embodiment, a sealing ring 105 is provided on the side of the main body 100 near the spline shaft 501 to increase the relative sealing of the first working groove 101 after the main body 100 is installed and connected, and to prevent the working oil from overflowing from the side of the main body 100.

[0056] As Figure 1 shown, in an optional embodiment, the main body 100 is provided with an annular groove 104, the sealing ring 105 is embedded in the annular groove 104, and the thickness of the sealing ring 105 is greater than the depth of the annular groove 104, the inner diameter of the sealing ring 105 is greater than the inner diameter of the spline inner gear ring 502, and the outer diameter of the sealing ring 105 is less than the outer diameter of the spline inner gear ring 502.

[0057] The annular groove 104 maintains the installation accuracy of the sealing ring 105 and prevents the sealing ring 105 from falling off. In addition, the depth of the annular groove 104 is set to increase the thickness of the sealing ring 105, so that after the main body 100 is completed and connected, the sealing ring 105 is deformed by the extrusion of the main body 100 and the spline inner gear ring 502, and a more stable sealing effect is provided at the annular groove 104.

[0058] As Figure 1 shown, the inner diameter of the sealing ring 105 is greater than the inner diameter of the spline inner gear ring 502, and the outer diameter of the sealing ring 105 is less than the outer diameter of the spline inner gear ring 502. By controlling the inner diameter and the outer diameter of the sealing ring 105, the space constrained by the sealing ring 105 can be outside the connection between the spline shaft 501 and the spline inner gear ring 502, so as to maintain the stable coverage of the oil in the first working groove 101 on the connection area between the spline shaft 501 and the spline inner gear ring 502, and improve the coverage effectiveness of the oil.

[0059] As Figure 1 shown, in an optional embodiment, the supplement 200 adopts a fluid pump to maintain that the working oil can be stably delivered into the first working groove 101.
