[0018] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.
[0019] Please see Figure 1-5 It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the disclosed technical content. Furthermore, the terms "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.
[0020] Please see Figures 1 to 5 This utility model provides a simplified high-efficiency transmission gear set 100, which includes a gear 1, a gear ring shaft 2 and a rotating shaft 3 arranged coaxially. The gear 1 is sleeved on the gear ring shaft 2 and is fixedly connected to the gear ring shaft 2.
[0021] Combination Figure 1-2 The gear ring shaft 2 includes a body 21 and a limiting part 22 and a gear ring part 23 sequentially disposed on the outer peripheral surface of the body 21. The gear 1 is sleeved on the body 21 and abuts against the limiting part 22. The body 21 includes a first through hole 211 disposed along the axial direction of the body 21.
[0022] Combination Figure 2-5 Furthermore, the rotating shaft 3 includes a shaft body 31 and a stop portion 32 disposed at the bottom of the shaft body 31. The shaft body 31 passes through the first through hole 211 and is rotatably mounted in the first through hole 211 by means of a bearing.
[0023] Furthermore, the stop portion 32 abuts against the side of the gear ring portion 23 away from the limiting portion 22.
[0024] By designing the gear ring shaft 2, the original multi-stage gear meshing structure is simplified into a composite structure, which reduces assembly difficulty while ensuring transmission accuracy.
[0025] Please refer to 1-2. Gear 1 includes a wheel body 11 and gear teeth 12 disposed on the outer circumferential surface of the wheel body 11.
[0026] The wheel body 11 is provided with a first mounting hole 111, and the limiting part 22 is provided with a second mounting hole 221 with the same diameter as the first mounting hole 111. The first mounting hole 111 and the second mounting hole 221 are provided in a one-to-one correspondence.
[0027] Furthermore, the wheel body 11 is fixedly installed on the limiting part 22 by screws passing through the first mounting hole 111 and the second mounting hole 221 in sequence.
[0028] The first mounting hole 111 and the second mounting hole 221 are set in a one-to-one correspondence, so that the wheel body 11 can be fixedly installed on the limiting part 22, while ensuring the coaxial rotation between the gear 1 and the gear ring shaft 2, thus ensuring the transmission accuracy of the entire device.
[0029] Please continue reading. Figure 3-5 The maximum outer diameter of the stop part 32 is greater than the inner diameter of the first through hole 211.
[0030] The rotating shaft 3 passes through the first through hole 211 along the gear ring portion 23 toward the limiting portion 22. The stop portion 32 is used to abut against the side of the gear ring portion 23 away from the limiting portion 22. The design of the stop portion 32 controls the length of the rotating shaft 3 inserted into the first through hole 211, accurately locks the installation position of the rotating shaft 3, and greatly improves the assembly efficiency of the device.
[0031] Please continue reading. Figure 1 The wheel body 11 has several weight-reducing holes 112 evenly arranged around the axis of the wheel body 11.
[0032] Several weight-reducing holes 112 are opened on the wheel body 11, which can reduce production costs while ensuring a certain rigidity of the gear 1, and reduce the inertial load on the gear 1 during startup. This can greatly improve the service life of the gear 1.
[0033] In this embodiment, the weight-reducing hole 112 is circular. In other embodiments, the shape of the weight-reducing hole 112 is not limited and can be triangular, rectangular, or other polygonal. However, it should be noted that the weight-reducing holes 112 must be evenly distributed and the center of gravity of gear 1 must not be changed; otherwise, the lifespan of gear 1 will be greatly reduced.
[0034] Please continue reading. Figure 2 The gear ring shaft 2 is integrally die-cast and is a composite structure. As an intermediate structure in the transmission process, the integral molding process can greatly improve its structural strength.
[0035] The simplified high-efficiency transmission gear set 100 of this utility model is implemented as follows: During assembly, the rotating shaft 3 enters from the first through hole 211 along the direction of the gear ring portion 23 toward the limiting portion 22 and is rotatably installed on the gear ring shaft 2 until the stop portion 32 abuts against the bottom of the gear ring portion 23. The two are connected by bearings. The gear 1 is sleeved on the body 21 along the direction of the limiting portion 22 toward the gear ring portion 23 until the wheel body 11 abuts against the limiting portion 22. The gear 1 is fixedly installed on the limiting portion 22 by screws. At this time, the gear 1 is assembled, and the gear 1, gear ring shaft 2 and rotating shaft 3 maintain coaxial rotation. During operation, the gear ring shaft 2 can connect to a toothed belt or mesh with other power wheels. Since the gear 1 and gear ring shaft 2 rotate synchronously, the gear ring shaft 2 can accurately transmit power to the gear 1, and the rotating shaft 3 ensures that the three rotate coaxially.
[0036] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
