DETAILED DESCRIPTION
[0032] In order to facilitate understanding by those skilled in the art, the present invention is further described below in conjunction with the accompanying drawings.
[0033] Please refer to Figure 1-Figure 3, which is an embodiment of the staggered tooth ring floating support structure provided by the utility model, includes a platform 1; a plurality of circumferentially distributed rolling support assemblies 2 are arranged on the platform 1, and the rolling support assembly 2 includes a support seat 21 and a roller 22, and the roller 22 is rotatably arranged on the support seat 21, and the staggered tooth ring 4 is placed on the roller 22 and can rotate around its axis. There is rolling friction between the staggered tooth ring 4 and the roller 22, which can effectively reduce the friction force; an elastic member 3 is arranged between the platform 1 and the support seat 21, when the support seat 21 is not subjected to external force, the elastic member 3 forms a first gap between the support seat 21 and the platform 1 in the vertical direction, and at the same time, there is a second gap between the staggered tooth ring 4 and the platform 1, thereby realizing the floating support of the staggered tooth ring 4, so that the staggered tooth ring 4 can realize automatic adjustment and self-protection when rotating, further improving the smoothness of the staggered tooth ring 4 when rotating and reducing noise, and the staggered tooth ring 4 can effectively adapt to the wear and thermal expansion in long-term operation, and ensure the performance and production efficiency of the vulcanizer.
[0034] For details, please refer to Figure 1 A vulcanizing body is provided on the platform 1, and the vulcanizing body includes a base 61 and an upper steam chamber 62 located above the base 61. The base 61 is placed on the platform 1. The staggered tooth ring 4 can rotate to lock the upper steam chamber 62 and the base 61 to form a closed vulcanizing chamber 63. The tire mold 7 is located in the vulcanizing chamber 63, and the vulcanization of the tire can be achieved; the staggered tooth ring 4 can use its staggered tooth structure to realize the state switching between the locking and separation of the upper steam chamber 62 and the base 61 by rotating. The matching structure between the staggered tooth ring 4, the upper steam chamber 62 and the base 61 is a common structure in the technical field, which will not be described in detail here.
[0035] It should be noted that when the present invention is actually used, under the action of the elastic member 3, the height of the staggered tooth ring 4 will rise to a certain extent. At this time, the fit between the upper steam chamber 62 and the staggered tooth ring 4 may produce a gap and become loose, and it is necessary to actively lower the height of the staggered tooth ring 4 to make the upper steam chamber 62 and the base 61 tightly locked; for this problem, a limit screw can be set inside the placement hole 11 to limit the width of the first gap between the support seat 21 and the platform 1, or the depth of the placement hole 11 can be deepened, or an elastic member 3 with a shorter length and a larger deformation amount can be selected to lower the height of the staggered tooth ring 4, etc., to avoid the situation where the upper steam chamber 62 and the staggered tooth ring 4 do not fit tightly.
[0036] In this embodiment, please refer to Figure 2 and Figure 3 A gasket 5 is provided in the second gap between the platform 1 and the staggered tooth ring 4. The gasket 5 is preferably distributed around the support seat 21 in the second gap. The gasket 5 can protect the elastic member 3 and prevent the elastic member 3 from being compressed to the limit. In other embodiments, the gasket 5 can also be provided in the first gap between the support seat 21 and the platform 1, so as to effectively protect the elastic member 3.
[0037] For details, please refer to Figure 2 and Figure 3 The difference between the second gap width and the thickness of the gasket 5 should be smaller than the first gap width to prevent the gasket 5 from affecting the normal rotation of the staggered tooth ring 4. When the staggered tooth ring 4 abuts against the gasket 5, the first gap still has a certain width to prevent the elastic member 3 from being compressed to the limit; accordingly, the gasket 5 is fixed on the upper surface of the platform 1; in other embodiments, the gasket 5 can also be fixed on the lower surface of the staggered tooth ring 4, so as to effectively prevent the elastic member 3 from being compressed to the limit.
[0038] In this embodiment, please refer to Figure 2 and Figure 3 A placement hole 11 matching the shape of the support seat 21 is provided on the platform 1, and the lower end of the support seat 21 is embedded in the placement hole 11. The support seat 21 and the placement hole 11 are clearance-matched, which can effectively position the support seat 21. At the same time, the support seat 21 can move slightly in the vertical direction relative to the platform 1 to achieve floating support for the right and wrong gear rings 4.
[0039] Based on the above examples, please refer to Figure 2 and Figure 3 A first step surface 111 is provided on the side wall of the placement hole 11, and a second step surface 211 is provided on the side wall of the support seat 21. The second step surface 211 is located above the first step surface 111. One end of the elastic member 3 abuts against the first step surface 111, and the other end of the elastic member 3 abuts against the second step surface 211. The elastic member 3 is in a compressed state. The elastic member 3 can produce corresponding deformation according to the force applied to the support seat 21. The support seat 21 moves slightly accordingly and floats to support the staggered tooth ring 4.
[0040] For clarification, please refer to Figure 2 and Figure 3 The first step surface 111 and the second step surface 211 are preferably set to be annular surfaces arranged around the support seat 21, and six elastic members 3 are arranged between the first step surface 111 and the second step surface 211. The six elastic members 3 are evenly distributed around the support seat 21, and the support seat 21 can be stably raised and lowered when subjected to force; in other embodiments, the number of elastic members 3 can also be set to other values or directly mounted on the support seat 21, so as to be able to stably apply elastic force to the support seat 21.
[0041] It should be noted that the elastic member 3 is preferably configured as a spring; in other embodiments, the elastic member 3 may also be configured as a spring sheet, so as to be able to generate a stable elastic force when deformed.
[0042] In this embodiment, please refer to Figure 1-Figure 3The roller 22 is configured as a spherical roller, and a receiving cavity 212 matching the spherical roller is provided on the support seat 21. The spherical roller is rotatably embedded in the receiving cavity 212. Specifically, more than half of the spherical roller should be embedded in the receiving cavity 212 to ensure that the spherical roller rotates stably in the receiving cavity 212; the upper edge of the spherical roller is exposed from the receiving cavity 212 and abuts against the staggered tooth ring 4 to achieve rolling friction with the staggered tooth ring 4; in other embodiments, the roller 22 can also be configured as a cylindrical roller, based on the rolling friction between the staggered tooth ring 4 and the roller 22 when rotating.
[0043] Based on the above examples, please refer to Figure 2 and Figure 3 A rolling groove 41 is provided on the lower surface of the staggered tooth ring 4, and the upper edge of the spherical roller extends into the rolling groove 41 and abuts against the inner wall surface of the rolling groove 41 to achieve a rolling connection; specifically, the rolling groove 41 is preferably set as an annular groove, and when the staggered tooth ring 4 rotates, the spherical roller rolls stably along the annular groove; in other embodiments, since the staggered tooth ring 4 only swings back and forth within a certain angle when in use, the rolling groove 41 can also be composed of a plurality of circumferentially distributed arc sub-grooves, so that the spherical roller always rolls in the arc sub-groove.
[0044] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
