Specific implementation

[0023] In order to make the purpose, technical scheme and advantage of the embodiments of the present disclosure clearer, the technical scheme of the embodiments of the present disclosure will be described clearly and completely below in combination with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present disclosure.

[0024] As shown in Figures 1-7 A combined driving axle device with self-lubricating structure, comprising a base 1 and a rotating wheel 2, the rotating wheel 2 is rotationally arranged on the base 1 through a rotating shaft 21, a rotating seat 3 and a rubber seat 4 are arranged in the base 1, a communication hole 121 that is in communication with an oil storage cavity 12 is formed in the base 1, the rotating seat 3 is coaxially rotationally arranged with the rotating wheel 2, and the rubber seat 4 blocks the communication hole 121 in the default state, a plurality of convex plates 31 are circumferentially arranged on the rotating seat 3, and an oil guide groove 32 and an oil guide hole 33 that are in communication are formed on the rotating seat 3, the communication hole 121 faces the oil guide groove 32, and the outlet 332 of the oil guide hole 33 faces the rotating shaft 21, the rotating seat 3 is driven to rotate by the rotating shaft 21 to periodically extrude the rubber seat 4 to deform and expose the communication hole 121.

[0025] Specifically, as shown in Figure 2 The rotating shaft 21 of the rotating wheel 2 is rotationally arranged in the rotating hole 11 of the base 1, the rotating seat 3 is also rotationally arranged in the rotating hole 11, the oil storage cavity 12 and the communication hole 121 are formed in the base 1, the oil storage cavity 12 is in communication with the rotating hole 11 through the communication hole 121, and the injection hole for injecting oil into the oil storage cavity 12 is also arranged on the base 1, and as Figure 3As shown, the rotating seat 3 is provided with an oil guiding groove 32 and an oil guiding hole 33, the inlet 331 of the oil guiding hole 33 is communicated with the oil guiding groove 32, and the outlet 332 of the oil guiding hole 33 is communicated with the inner ring side of the rotating seat 3 to face the circumference of the rotating shaft 21, and as shown Figure 5 As shown, the rubber seat 4 is in the default state to block the communication hole 121, and when the rotating shaft 21 drives the rotating wheel 2 to rotate on the base 1, the rotating shaft 21 and the rotating seat 3 have friction to enable the rotating shaft 21 to drive the rotating seat 3 to rotate synchronously, at this time, the convex plate 31 provided on the rotating seat 3 rotates circumferentially to contact the rubber seat 4, the convex plate 31 drives the rubber seat 4 to deform and no longer block the communication hole 121, so that the oil in the oil storage cavity 12 can flow into the oil guiding groove 32, and due to the existence of centrifugal force, the oil in the oil guiding groove 32 at this time cannot enter the oil guiding hole 33, when the rotating seat 3 continues to rotate and the oil fills the oil guiding groove 32 through the communication hole 121, under the action of hydraulic pressure, the oil can flow to the circumference of the rotating shaft 21 through the oil guiding hole 33 to realize the automatic lubrication effect of the rotating shaft 21 in the running process, reduce the friction between the rotating shaft 21 and the base 1, and reduce the rotational jitter of the rotating shaft 21 and the rotating wheel 2, and improve the driving safety of the rotating wheel 2. Secondly, since the oil is in the oil guiding groove 32 and enters the oil guiding hole 33 under the hydraulic pressure in the oil storage cavity 12, the oil guiding groove 32 is always filled with oil, and in the process of rotating the rotating seat 3 and the rotating shaft 21, the oil in the oil guiding groove 32 can further lubricate the rotating seat 3 and absorb the friction heat of the rotating seat 3 and the rotating shaft 21, and secondly, when the rotating shaft 21 stops rotating, the oil in the oil guiding groove 32 flows into the oil guiding hole 33 due to the disappearance of the rotational centrifugal force and the gravity, and further can continuously lubricate and maintain when the rotating shaft 21 does not rotate, to avoid rust and damage of the rotating shaft 21 due to long-term non-use.

[0026] Among them, the base 1 is also provided with a driving assembly 9 for driving the rotating shaft 21 to rotate, and the driving assembly 9 is a common technical knowledge of those skilled in the art, which is not described here.

[0027] In the above technical solution, the rotating shaft 21 drives the rotating seat 3 to rotate synchronously. The circumferential rotation of the protruding plate 31 on the rotating seat 3 causes the rubber seat 4 to deform and no longer block the connecting hole 121, so that the oil in the oil storage chamber 12 can flow into the oil guide groove 32. Due to the centrifugal force, the oil in the oil storage groove 32 will not enter the oil guide hole 33. When the rotating seat 3 continues to rotate and the oil fills the oil guide groove 32 through the connecting hole 121, under the action of hydraulic pressure, the oil can flow to the circumference of the rotating shaft 21 through the oil guide hole 33 for lubrication, thereby realizing the automatic lubrication effect of the rotating shaft 21 during operation, reducing the friction between the rotating shaft 21 and the base 1, reducing the rotational vibration of the rotating shaft 21 and the rotating wheel 2, and improving the driving safety of the rotating wheel 2. Secondly, since the oil is located in the oil guide groove 32 and enters the oil guide hole 33 by the hydraulic pressure in the oil storage chamber 12, the oil guide groove 32 is always full of oil. During the rotation of the rotating seat 3 and the rotating shaft 21, the oil in the oil guide groove 32 can further lubricate the rotating seat 3 and absorb the frictional heat of the rotating seat 3 and the rotating shaft 21. Furthermore, when the rotating shaft 21 stops rotating, the oil in the oil guide groove 32 continuously flows into the oil guide hole 33 due to the disappearance of the centrifugal force of rotation. Thus, it can continuously lubricate and maintain the rotating shaft 21 even when it is not rotating, and prevent the rotating shaft 21 from rusting and being damaged due to long-term disuse.

[0028] As a further embodiment of this utility model, a shielding cover 5 coaxial with the rotating shaft 21 is symmetrically arranged on the base 1. The shielding cover 5 is located on both sides of the base 1. A bearing 6 sleeved on the outside of the rotating shaft 21 is arranged inside the shielding cover 5. A sealing ring 7 is also arranged inside the shielding cover 5. The bearing 6 is located between the sealing ring 7 and the base 1.

[0029] Specifically, such as Figure 2 As shown, the shielding cover 5 is disposed on both sides of the base 1 to cover both sides of the rotating shaft 21. The presence of the bearing 6 can improve the stability of the rotating shaft 21 rotating on the base 1. The bearing 6 is located between the sealing ring 7 and the base 1. Thus, the shielding cover 5 and the sealing ring 7 can further seal and prevent dust from entering the base 1 along the surface of the rotating shaft 21, thus preventing the rotating shaft 21 from getting stuck and improving the rotational stability of the rotating shaft 21. Secondly, the presence of the sealing ring 7 can also reduce the loss of oil from the surface of the rotating shaft 21 inside the base 1, thereby increasing the effective lubrication time.

[0030] As a further embodiment of this utility model, the cover 5 is provided with a fitting groove 51, and rubber blocks 8 are symmetrically arranged inside the cover 5. The base 1 is provided with an embedding part 13. The cover 5 is installed on the base 1 so that the embedding part 13 is embedded in the fitting groove 51, and the embedding part 13 squeezes the rubber block 8 to deform so as to squeeze the sealing ring 7 to contact the annular surface of the rotating shaft 21.

[0031] Specifically, the cover 5 has a fitting groove 51, and the base 1 has an embedding part 13. When the cover 5 is installed on the base 1 to seal and prevent dust from entering both ends of the rotating shaft 21, the cover 5 is installed in the base 1, thereby further improving the installation stability of the cover 5 on the base 1 and ensuring the protection of the rotating shaft 21 by the cover 5. Secondly, the embedding part 13 enters the fitting groove 51 to squeeze the rubber block 8 to deform and squeeze the sealing ring 7 to contact the annular surface of the rotating shaft 21, thereby further improving the sealing performance between the sealing ring 7 and the surface of the rotating shaft 21, and further improving the dust prevention and sealing effect of the rotating shaft 21.

[0032] As a further embodiment of this utility model, the cover 5 is symmetrically provided with an extension 52, and the rotating seat 3 is symmetrically provided with annular movable grooves 34 on both sides. The cover 5 is installed on the base 1 so that the end of the extension 52 abuts against the movable groove 34.

[0033] Specifically, such as Figure 4 As shown, extensions 52 are symmetrically arranged on the cover 5. When the cover 5 is installed on the base 1 to seal and prevent dust from entering both ends of the rotating shaft 21, the ends of the extensions 52 abut against the movable groove 34. When the rotating seat 3 rotates with the rotating shaft 21, the ends of the extensions 52 rotate and slide within the movable groove 34. By using the extensions 52 of the cover 5 to abut against both ends of the axial direction of the rotating seat 3, the axial rotational stability of the rotating seat 3 is further improved, and the axial vibration of the rotating shaft 21 caused by the rotating seat 3 being located within the base 1 is avoided. This further improves the rotational stability of the rotating shaft 21 and reduces safety hazards.

[0034] As a further embodiment of this utility model, the rubber seat 4 is provided with a blocking part 41 and a protruding part 42. The rubber seat 4 is in the default state so that the blocking part 41 blocks the connecting hole 121. The rotating seat 3 is driven to rotate so that the protruding plate 31 pushes against the protruding part 42 to drive the rubber seat 4 to deform and then disengage.

[0035] Specifically, such as Figure 5 As shown, the rubber seat 4 is provided with a sealing part 41 and an extension part 42. When the rotating seat 3 rotates with the rotating shaft 21 due to friction, the protruding plate 31 on the rotating seat 3 rotates circumferentially to abut against the extension part 42 on the rubber seat 4. The protruding plate 31 moves to push against the extension part 42, driving the rubber seat 4 to deform, thereby causing the sealing part 41 to leave and no longer block the connecting hole 121. At this time, the oil in the oil storage chamber 12 can flow into the guide oil groove 32 through the connecting hole 121. When the protruding plate 31 continues to rotate circumferentially and disengages from the extension part 42, the rubber seat 4 is reset by its own elastic deformation to block the connecting hole 121 again, thereby realizing the periodic outflow of oil at the position of the connecting hole 121 and avoiding the problem of oil overflow caused by rapid flow of oil to the periphery of the rotating shaft 21.

[0036] As the further provided embodiment of the utility model, the sealing ring 7 is a rubber product.

[0037] Specifically, the sealing ring 7 is a rubber product to improve the sealing property of the sealing ring 7.

[0038] The above only describes some exemplary embodiments of the utility model by way of illustration, without doubt, for ordinary skilled in the art, under the condition that the spirit and scope of the utility model are not deviated, the described embodiments can be modified in various different ways, therefore, the above drawings and description are illustrative in nature, should not be understood as the limitation of the utility model claim protection scope.
