Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The present embodiment is only for explanation of the present invention and is not to be construed as limiting the present invention, and modifications to the present embodiment, which may not creatively contribute to the present invention as required by those skilled in the art after reading the present specification, are all protected by patent laws within the scope of claims of the present invention.
As shown in fig. 1 and 2, a rotary body supporting wheel of a sterilization kettle comprises a fixed shell 1 and a central shaft 2. A plurality of bearings 3 are arranged between the fixed shell 1 and the central shaft 2, and a first positioning block 4 and a second positioning block 5 which separate and limit the bearings 3 are arranged between any two adjacent bearings 3. One side of the first positioning block 4 is fixedly connected with the fixed shell 1, and one side of the second positioning block 5 is fixedly connected with the central shaft 2.
The both ends of fixed shell 1 all are provided with fixed lid 6, and interference fit has two mutually independent first skeleton sealing washer 7 and second skeleton sealing washer 8 between every fixed lid 6 and the center pin 2. The fixed cover 6 is fixedly connected with a boss 9 between the first framework sealing ring 7 and the second framework sealing ring 8, and a gap is reserved between the boss 9 and the central shaft 2, so that a closed containing cavity 10 is formed by the gap under the action of the framework sealing rings at two sides. The two mutually independent framework sealing rings are used for forming a double sealing structure, and the first framework sealing ring 7 can limit the external liquid to enter the supporting wheel and contact with the bearing 3, and the second framework sealing ring 8 can limit the leakage of lubricating oil in the bearing 3.
The boss 9 is respectively abutted with the two side framework sealing rings, and the contact area between the fixed cover 6 and the two framework sealing rings is increased, so that the surface sealing effect is ensured. Meanwhile, as the supporting wheel is positioned in the sterilization kettle in a high-pressure environment, the pressure in the kettle can act on the first framework sealing ring 7, so that the first framework sealing ring 7 is extruded into the containing cavity 10, and the surface sealing effect between the first framework sealing ring 7 and the boss 9 is enhanced in the extrusion process. Meanwhile, as a gap is reserved between the boss 9 and the central shaft 2, when the first framework sealing ring 7 extrudes towards the boss 9, the first framework sealing ring 7 deforms under the action of the right-angle edge of the boss 9 towards one side of the central shaft 2, so that the first framework sealing ring 7 is extruded towards the central shaft 2, and the sealing effect between the first framework sealing ring 7 and the central shaft 2 is improved.
Further, the fixed cover 6 is fixedly connected with the fixed shell 1 through a fastener. The fastener is preferably a fastening screw 11.
Further, a notch 12 is arranged at the joint of each fixed cover 6 and the fixed shell 1, and an O-shaped sealing ring 13 is arranged in each notch 12. The fixed cover 6 is detachably and fixedly connected with the fixed shell 1, so that the fixed cover 6 and the fixed shell 1 are in a relatively static state. By providing the recess 12 in the stationary cover 6, so that an O-ring 13 is placed in the recess 12, the O-ring 13 prevents liquid from entering the inside of the support wheel and coming into contact with the bearing 3 in static conditions.
Further, as shown in fig. 1 and 3, both ends of the center shaft 2 are provided with screw holes 14 penetrating the center shaft 2. Each threaded bore 14 is threadably connected to an adjustment screw 15. The height of the central shaft 2 and thus the position height of the supporting wheel can be adjusted by the action of the adjusting screw 15 so as to adjust the position height of the revolving body supported by the supporting wheel according to the requirement. During use, the central shaft 2 is restrained from rotation by the adjusting screw 15. At the same time, the stationary housing 1, the stationary cover 6 and the bearing 3 rotate about the central shaft 2 by the rotation body.
Further, the bearings 3 in the present embodiment are preferably two. By providing two bearings 3 for ease of assembly. Only two bearings 3 are needed to be respectively placed between the fixed shell 1 and the central shaft 2, and the first positioning block 4 and the second positioning block 5 are used for separating the two bearings 3, so that the assembly efficiency is improved. Under the effect of fastener, assemble fixed lid 6 and O type sealing washer 13, skeleton sealing washer in proper order for this supporting wheel has simple structure, the characteristics of being convenient for assemble.
