For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Please see Figures 1-4 This utility model provides an embodiment of a computer spring mechanism for rotating core transmission, comprising a gear transmission plate 1, a drive gear 2 disposed inside the gear transmission plate 1, and a rotating core gear 3 disposed above the drive gear 2 and inside the gear transmission plate 1, as shown in the attached specification. Figure 3 As shown, the diameter of the rotating core gear 3 is larger than the diameter of the driving gear 2;

[0023] For further details, please refer to the appendix to the instruction manual. Figure 4 As shown, the outer wall of the rotating gear 3 is provided with a number of evenly distributed teeth 5. The driving gear 2 and the rotating gear 3 are meshed and connected. Each tooth 5 has a side groove 6 on both sides of its outer wall. An inner roller 7 is rolled inside each side groove 6. The outer edges of each tooth 5 are designed with an arc edge 8. Compared with the traditional right angle edge, this utility model can improve the smoothness of contact when the two teeth rotate and mesh, and improve the use effect.

[0024] Based on the above structure, this utility model features rolling inner rollers 7 installed on the side of each tooth 5 of the rotating gear 3. These inner rollers 7 mesh with the teeth of the driving gear 2. This design, during the rotation of the rotating gear 3 driven by the driving gear 2, improves the traditional sliding friction contact between teeth to the rolling friction contact of this utility model due to the rolling contact between the teeth of the driving gear 2 and the teeth 5 of the rotating gear 3. This effectively reduces the frictional contact between the teeth of the two gears during gear transmission, thus reducing the transmission friction and achieving low-wear gear transmission characteristics. It effectively reduces and delays wear between gears, while also preventing excessive temperature rise due to excessive friction, resulting in better structural performance and extending the overall service life of the transmission structure.

[0025] In this embodiment, in order to ensure normal use of the rotating core transmission, the center of the front of the rotating core gear 3 is provided with a mounting hole 4 for shaft connection, the middle position of the rotating core gear 3 is provided with a rotating core shaft 11, and the tail end of the rotating core shaft 11 is fixedly installed with a shaft seat 12 that matches the mounting hole 4. The shaft seat 12 is provided with a hole that matches the mounting hole 4 for connecting the shaft and the gear.

[0026] The rotating shaft 11 can be mounted on the mounting hole 4 of the rotating gear 3 by means of the set bearing 12, so that the rotating shaft 11 can be driven to rotate synchronously by the set rotating gear 3.

[0027] In this embodiment, in order to ensure the normal transmission operation of the gear transmission plate 1, a circular slot is provided on the front side of the gear transmission plate 1 and outside the mounting hole 4. The circular slot is the output port 13.

[0028] Furthermore, an input port 9 is provided at the center of the back of the drive gear 2 and on the outside of the gear transmission plate 1.

[0029] In this embodiment, in order to drive the components inside the gear transmission plate 1, a rotary drive 10 is fixedly installed on the outside of the input port 9 on the back of the gear transmission plate 1. The rotation shaft of the rotary drive 10 is fixedly connected to the drive gear 2. The rotary drive 10 is a motor. The rotary drive 10 can drive the drive gear 2 at the top to rotate actively through its rotation shaft, so as to ensure the normal transmission of the transmission mechanism of this utility model.

[0030] Working principle: When in use, the transmission mechanism of this utility model can be installed on the computer spring machine as a whole. The rotation drive component 10 of this utility model can drive the drive gear 2 to rotate through its output shaft.

[0031] Since the driving gear 2 and the rotating core gear 3 are meshed together, when the driving gear 2 rotates, the rotating core gear 3 meshing with it can rotate driven. Thus, the rotation of the rotating core gear 3 can synchronously drive the rotating core shaft 11 to rotate, thereby ensuring the normal rotation transmission effect of this utility model.

[0032] This invention features rolling inner rollers 7 mounted on the side of each tooth 5 of the rotating gear 3. These inner rollers 7 mesh with the teeth of the driving gear 2. This design improves the traditional sliding friction contact between teeth to rolling friction contact during the rotation of the rotating gear 3 driven by the driving gear 2. The inner rollers 7 effectively reduce friction between the teeth, thus reducing transmission friction and providing low-wear transmission characteristics. This effectively reduces and delays wear between gears, while preventing excessive temperature rise due to friction. The overall structural performance is improved, extending the service life of the transmission structure.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
