Description

Technical Field

[0001] This utility model belongs to the technical field of tire vulcanization process production equipment, specifically relating to a bearing lubrication structure and its vulcanizing machine. Background Technology

[0002] Existing technologies provide tire vulcanizing machines centered around various electric vulcanizing devices. When tire vulcanization is required, an external medium source supplies pressurized medium to the vulcanizing bladder of the tire vulcanizing machine, causing the bladder to expand and squeeze the tire from the inside, resulting in a high-pressure state within the bladder cavity. Electricity is used to heat and ventilate the medium (such as a gaseous medium like nitrogen) within the vulcanizing bladder. The tire vulcanizing machine is also equipped with a fan and impeller agitator, driven by a rotating device such as an electric motor to agitate the medium, ensuring its flow and uniform heat distribution, thus providing the heat required for vulcanization. After the tire vulcanization process is complete, the medium is removed from the vulcanizing bladder, causing it to shrink and the cavity to be under low pressure.

[0003] A bearing chamber is provided between the component used to drive the rotation of the agitator and the ring seat. The upper part of the bearing chamber is isolated from the inner cavity of the capsule by a seal. As the vulcanizing machine runs and stops, the bearing chamber experiences periodic changes in high and low pressure environments. This results in a lack of grease inside the bearing, which means that the bearing lacks the protective effect of grease during operation and will greatly shorten the service life of the bearing.

[0039] Please refer to Figures 1-3This utility model provides an embodiment of a bearing lubrication structure, including a center rod 6, an annular seat 1, a support cylinder 2, a rotating cylinder 3, a bearing 8, a clamping block 4, a baffle 5, a grease injection groove 7, and a grease injection channel 9. The center rod 6 is vertically arranged. The annular seat 1 has a central through hole in the axial direction and is configured as a stepped cylindrical structure. The upper part of the support cylinder 2 is fixed to the lower part of the annular seat 1 in the axial direction. The support cylinder 2 has a central through hole for the center rod 6 to pass through. The rotating cylinder 3 is at least partially disposed in the central through hole of the support cylinder 2 and the annular seat 1. The upper part of the rotating cylinder 3 is rotatably disposed in the central through hole of the annular seat 1 and extends through the annular seat 1. At the upper part of seat 1, bearing 8 is disposed between rotating cylinder 3 and ring seat 1. The bearing 8 is disposed in a way that allows rotating cylinder 3 to rotate relative to ring seat 1. Clamping block 4 is disposed on ring seat 1 and sleeved on the outside of rotating cylinder 3. The lower end face of clamping block 4 abuts against ring seat 1 and baffle 5. Baffle 5 is disposed between bearing 8 and clamping block 4. Baffle 5 is pressed against the upper end face of bearing 8. A grease injection groove 7 is provided at the end of baffle 5 near bearing 8. Grease enters bearing 8 through grease injection groove 7 to lubricate bearing 8. Grease injection channel 9 is disposed on ring seat 1 and communicates with grease injection groove 7 for injecting grease into grease injection groove 7.

[0040] Furthermore, in this embodiment, referring to Figures 2-5 The grease injection groove 7 is located on the lower end face of the baffle 5 near the bearing 8. The grease injection groove 7 includes a radial groove 71 and a radial groove 72. The radial groove 71 is configured as an annular groove surrounding the baffle 5. Several radial grooves 72 are configured to surround the lower end face of the baffle 5. The annular groove is located above the radial groove 72 along its axial direction. The radial groove 72 is configured as a groove opened in the radial direction from the inner ring of the annular groove towards the center. The annular groove and the radial groove 72 are interconnected. Part of the radial groove 72 is located on the outer ring of the bearing 8 in the radial direction and extends to the top of the bearing 8 balls. The grease can flow into the bearing 8 balls through the radial groove 72.

[0041] In this embodiment, further referring to Figures 1-3 The grease injection channel 9 is located within the ring seat 1, and its outlet is connected to the grease injection groove 7. The grease injection components are mounted on the ring seat 1 and include an adapter 17, a one-way valve 18, and an oil cup 19. The adapter 17 is mounted on the ring seat 1. Both ends of the one-way valve 18 are connected to the adapter 17 and the oil cup 19, respectively. The end of the oil cup 19 furthest from the one-way valve 18 is designated as the grease inlet for injecting grease. The end of the adapter 17 furthest from the one-way valve 18 is connected to the inlet of the grease injection channel 9. The adapter 17 connects the grease injection channel 9 and the one-way valve 18, allowing the one-way valve 18 to inject grease along the grease injection channel 9, effectively preventing backflow of grease. The oil cup 19 stores a small amount of grease.

[0042] Furthermore, the grease injection channel 9 is configured as a straight through hole, and the adapter 17 and the grease injection groove 7 are directly connected through the grease injection channel 9. The grease travels the shortest distance in the grease injection channel 9 and can be injected into the bearing 8 in a shorter time. In other embodiments, the grease injection channel 9 is provided with a bend, so that the grease can be injected into the bearing 8.

[0043] Grease injection process: Grease is injected from oil cup 19 into check valve 18. Check valve 18 injects grease into grease injection channel 9 through adapter 17. The grease enters radial groove 71 through grease injection channel 9, then enters radial groove 72, and enters the upper end face of bearing 8 from radial groove 72, and then flows into the interior of bearing ball 8 to achieve the effect of lubricating bearing 8.

[0044] In this embodiment, refer to Figure 2 and Figure 3 This utility model also includes a first sealing part 10, a second sealing part 11, and a third sealing part 12. The first sealing part 10 is disposed between the pressing block 4 and the baffle 5 to prevent gas and impurities from entering the bearing 8. The third sealing part 12 is disposed on the upper part of the pressing block 4 and near the rotating cylinder 3 to prevent impurities in the capsule cavity 15 from entering the bearing 8. The second sealing part 11 is disposed between the upper part of the support cylinder 2 and the rotating cylinder 3 to isolate the bearing 8 from the gap between the support cylinder 2 and the rotating cylinder 3.

The lower clamping assembly of the vulcanizing device 16 is fixed to the ring seat 1, preferably on the outside of the ring seat 1, and the upper clamping assembly is fixed to the upper part of the central rod 6 at the top of the vulcanizing device 16. Driving the central rod 6 to rise and fall can cause the vulcanizing capsule to close or expand.

[0046] In this embodiment, refer to Figure 1 This invention also includes a heating assembly 13, a stirring assembly 14, and a capsule cavity 15. The upper clamping assembly, lower clamping assembly, and the upper part of the vulcanizing capsule and the ring seat 1 of the vulcanizing device 16 together define the hollow capsule cavity 15. The heating assembly 13 and the stirring assembly 14 are disposed in the capsule cavity 15 of the vulcanizing device 16. The heating assembly 13 can heat the medium inside the capsule; the heating assembly 13 can be a coil-shaped heating source or a rod-shaped heating source. The stirring assembly 14 agitates the medium inside the capsule cavity 15 to improve the uniformity of the temperature field inside the capsule cavity 15.
