[0001] The utility model relates to the technical field of track rollers, in particular to a wear-resistant double-sided track roller which is easy to install. Background Art

[0002] Track rollers can be divided into single-sided track rollers and double-sided track rollers. Track rollers are used to support the weight of crawler engineering machinery.

DETAILED DESCRIPTION

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Example:

[0025] like Figures 1 to 5As shown, this embodiment provides a wear-resistant double-sided track roller that is easy to install, including a double-sided wheel body 1. The two axial end faces of the double-sided wheel body 1 are respectively provided with a coaxial outer mounting groove A2 and an inner mounting groove B3. A track roller shaft 4 is installed on the axis of the double-sided wheel body 1. The outward end of the track roller shaft 4 is provided with an axle seat A5 and the inward end is provided with an axle seat B6. The inward ends of the axle seat A5 and the axle seat B6 are installed in the mounting groove A2, and a floating seal ring 7 is installed in the mounting groove B3; a lubricating oil channel 8 is provided in the track roller shaft 4, and a transition chamber 9 is provided in the axle seat A5. The inlet end of the lubricating oil channel 8 is connected with the transition chamber 9. A pair of mutually symmetrical oil replenishing components 10 are provided on the axle seat A5. The outlet end of the oil replenishing component 10 is connected with the transition chamber 9. An opening and closing component 11 is provided on the transition chamber 9. The opening and closing component 11 is used to control the opening and closing of the connection between the oil replenishing component 10 and the transition chamber 9.

[0026] A pair of oil replenishing components 10 are provided on the outer shaft seat A5. The oil replenishing components 10 are used to replenish the lubricating oil channel 8 with lubricating oil through the transition chamber 9, which can reduce the frequency of replenishing the lubricating oil and reduce the maintenance burden; the two oil replenishing components 10 are symmetrically arranged to reduce the influence of eccentricity, and the opening and closing component 11 is used to interrupt the communication between the oil replenishing component 10 and the transition chamber 9 when the staff is filling the oil replenishing component 10 with oil, so that the lubricating oil can be smoothly injected into the oil replenishing component 10. After the oil replenishing component 10 is filled with oil, the opening and closing component 11 is reopened to restore the communication between the oil replenishing component 10 and the transition chamber 9, so that the oil replenishing component 10 can replenish the lubricating oil into the lubricating oil channel 8 through the transition chamber 9. The oil replenishing component 10 is arranged on the shaft seat A5 mounted on the outward end, which is convenient for the staff to perform oil replenishing operations. The mounting groove A2 for accommodating the shaft seat A5 or the shaft seat B6 and the mounting groove B3 for accommodating the floating seal ring 7 are coaxially located and on the same end face of the double-sided wheel body 1. During installation, the floating seal ring 7 can be installed first and then the shaft seat A5 and the shaft seat B6. The order is clear and the installation is convenient.

[0027] Furthermore, the oil replenishing assembly 10 includes an oil storage cylinder 12, a sliding plate 13, a sliding rod 14 and a spring 15. A pair of mutually symmetrical oil storage cylinders 12 are provided on the shaft seat A5. The internal cavity of the oil storage cylinder 12 is provided with a sliding rod 14 along the axis. The sliding rod 14 is slidably connected to the sliding plate 13. The shape of the sliding plate 13 is equivalent to the cross-sectional shape of the internal cavity of the oil storage cylinder 12. An oil filling port 16 and an oil drain port 17 are provided on the oil storage cylinder 12. The oil filling port 16 and the oil drain port 17 are on the same side of the sliding plate 13. A spring 15 is provided on the other side of the sliding plate 13. The spring 15 is connected between the sliding plate 13 and the bottom of the oil storage cylinder 12. An oil plug A18 is provided on the oil filling port 16. An oil delivery channel 19 connecting the oil drain port 17 and the transition chamber 9 is provided in the shaft seat A5.

[0028] By using the sliding plate 13, the sliding rod 14 and the spring 15 in combination, the lubricating oil in the oil reservoir 12 is kept at a pressure sufficient to enter the lubricating oil passage 8 along the oil delivery channel 19 and the transition chamber 9, thereby achieving the effect of timely replenishing the lubricating oil to the lubricating oil passage 8. When filling the oil replenishing assembly 10 with oil, the staff first closes the opening and closing assembly 11 and then opens the oil plug A18, and adds lubricating oil to the oil reservoir 12 from the oil filling port 16. At this time, due to the interruption of the communication between the oil delivery channel 19 and the transition chamber 9, the lubricating oil that continuously enters the oil reservoir 12 will push the sliding plate 13 along the sliding rod 14 to The bottom of the oil reservoir 12 moves, and the spring 15 is continuously compressed during this process. When the sliding plate 13 moves to the deepest point, the lubricating oil in the oil reservoir 12 reaches the maximum value. Then the staff first closes the oil plug A18 and then opens the opening and closing assembly 11. The connection between the oil delivery channel 19 and the transition chamber 9 is restored. Under the action of the elastic force of the spring 15 tending to restore its original shape, the sliding plate 13 continues to apply pressure to the lubricating oil to squeeze it out of the oil reservoir 12. When there is a shortage of lubricating oil in the lubricating oil channel 8, the lubricating oil in the oil reservoir 12 can be replenished into the lubricating oil channel 8 in time.

[0029] Furthermore, a sealing ring 20 is provided along the outer edge of the sliding plate 13 , and the sealing ring 20 slides against the inner wall of the oil storage cylinder 12 .

[0030] The gap between the outer edge of the sliding plate 13 and the inner wall of the oil storage cylinder 12 is blocked by the sealing ring 20 , thereby improving the sealing performance of the sliding plate 13 and reducing the probability of lubricating oil leaking through the sliding plate 13 .

[0031] Furthermore, the opening and closing assembly 11 includes a sealing cover 21 and an annular plate 22. The transition chamber 9 is cylindrical in shape. The inlet end of the lubricating oil channel 8 is coaxially connected to the transition chamber 9. The outlet end of the oil replenishing assembly 10 is connected to the side wall of the transition chamber 9. The sealing cover 21 is rotatably connected to the shaft seat A5. The rotating axis of the sealing cover 21 coincides with the central axis of the transition chamber 9. The inward end of the sealing cover 21 is provided with an annular plate 22 around the central axis. The annular plate 22 extends into the transition chamber 9. The outer diameter of the annular plate 22 is equivalent to the inner diameter of the transition chamber 9. A through hole 23 is provided on the annular plate 22, and the through hole 23 can be rotated to overlap with the outlet end of the oil replenishing assembly 10.

[0032] By rotating the sealing cover 21, the direction of the through hole 23 on the annular plate 22 connected to the sealing cover 21 is changed, thereby controlling whether the through hole 23 is connected to the outlet end of the oil replenishing assembly 10, and further controlling whether the oil replenishing assembly 10 and the transition chamber 9 are connected to each other. When the through hole 23 and the outlet end of the oil replenishing assembly 10 are staggered, the annular plate 22 blocks the connection between the oil replenishing assembly 10 and the transition chamber 9. When the through hole 23 and the outlet end of the oil replenishing assembly 10 overlap, the oil replenishing assembly 10 is connected to the transition chamber 9.

[0033] Furthermore, the communication between the outlet ends of the two oil replenishing assemblies 10 and the side wall of the transition chamber 9 is on the circumference of the same circular cross-section of the transition chamber 9 and the two are symmetrical about the center of the circular cross-section. The number of through holes 23 is two, and the two through holes 23 are on the circumference of the same circular cross-section of the annular plate 22 and the two are symmetrical about the center of the circular cross-section.

[0034] Through the symmetrical layout, the overlapping state between the outlet ends of the two oil replenishing components 10 and the through hole 23 is kept consistent, which facilitates the synchronous control of the communication state between the two oil replenishing components 10 and the transition chamber 9, and reduces the difficulty of the staff in filling oil into the oil replenishing components 10.

[0035] Furthermore, two screw holes A24 are provided on the sealing cover 21, and screw holes B25 corresponding to the screw holes A24 are provided on the shaft seat A5. Both screw holes A24 can be rotated to overlap with the screw holes B25. When one of the screw holes A24 overlaps with the screw holes B25, the through hole 23 is connected to the outlet end of the oil replenishing component 10. When the other screw hole A24 overlaps with the screw hole B25, the outlet end of the oil replenishing component 10 is blocked by the annular plate 22. The sealing cover 21 is fixed by screwing the positioning screws 26 into the overlapping screw holes A24 and screw holes B25.

[0036] By using screw hole A24, screw hole B25 and positioning screw 26 together, the staff can more conveniently rotate the sealing cover 21 to an angle where the through hole 23 overlaps or staggers with the outlet end of the oil replenishing assembly 10 and fix the sealing cover 21 at the desired angle.

[0037] Furthermore, the sealing cover 21 is provided with an oil replenishing port 27 along the central axis. The oil replenishing port 27 is communicated with the transition chamber 9 , and an oil plug B28 is provided on the oil replenishing port 27 .

[0038] When oil needs to be replenished immediately, the staff can directly inject oil into the lubricating oil channel 8 through the transition chamber 9 through the oil replenishing port 27. Before injecting oil, first interrupt the communication between the oil replenishing component 10 and the transition chamber 9, then open the oil plug B28 and inject oil from the oil replenishing port 27. After the oil injection is completed, close the oil plug B28 again.

[0039] The working principle and use process of this utility model:

[0040] To fill oil replenishment assembly 10, first close opening / closing assembly 11, then open oil plug A18 and pour oil into oil filling port 16. Once filling is complete, close oil plug A18 and reopen opening / closing assembly 11. To directly fill lubricating oil passage 8, first close opening / closing assembly 11, then open oil plug B28 and pour oil into oil replenishment port 27. Once filling is complete, close oil plug B28 and reopen opening / closing assembly 11.

[0041] To open the opening and closing assembly 11, first loosen the set screw 26 and rotate the screw hole A24, which was originally offset from the screw hole B25, until it overlaps with the screw hole B25. Then, tighten the set screw 26 on the overlapping screw holes A24 and B25 to fix the angle of the sealing cover 21. At this point, the through hole 23 in the annular plate 22 overlaps the outlet end of the oil replenishing assembly 10. Closing the opening and closing assembly 11 is similar: rotate the corresponding screw hole A24 until it overlaps with the screw hole B25 and connect the two with the set screw 26.

[0042] The above are only specific application examples of the present invention and do not constitute any limitation on the scope of protection of the present invention. Any technical solution formed by equivalent transformation or equivalent replacement shall fall within the scope of protection of the present invention.
