Description

Energy-saving gear transmission mechanism

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on September 22, 2023, with application number 202311240038.1 and application name “A Energy-Saving Gear Transmission Mechanism”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of power machinery technology, and in particular to an energy-saving gear transmission mechanism. Background Art

[0003] In power machinery, the rotation or speed change of multiple axes is often achieved through gear transmission. In a one-to-one primary transmission, the energy transmitted to the driven wheel is essentially equivalent to that of the driving wheel, with very little resistance loss. In a one-to-many primary transmission, under the same conditions and working environment, the energy transmitted to each driven wheel is basically evenly divided. In a one-to-two transmission, the energy received by each driven wheel is approximately half of the energy of the driving wheel, and in a one-to-three transmission, the energy received by each driven wheel is approximately one-third of the energy of the driving wheel. With the increasing demand for energy and the increasingly acute problem of energy conservation, how to make structural improvements to increase the energy received by multiple driven wheels without increasing the energy of the original power has always been an important research topic.

[0005] To this end, the present application provides an energy-saving gear transmission mechanism to solve the above-mentioned problems in the prior art.

[0006] In order to achieve the above objectives, this application provides the following technical solutions:

[0030] The following specific embodiments illustrate the implementation of this application. Those familiar with the art can easily understand the other advantages and functions of this application from the content disclosed in this specification. Obviously, the described embodiments are part of the embodiments of this application, but not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0031] Example 1

[0032] As shown in Figures 1 to 8, an energy-saving gear transmission mechanism in an embodiment of the first aspect of the present application includes a mounting frame 1, a driving wheel 2, and a plurality of driven wheels. The driving wheel 2 is disposed on a driving shaft 8, which is rotatably connected to the mounting frame 1, and one end of the driving shaft 8 is a power input end.

[0033] The plurality of driven wheels are respectively arranged in a ring array along the axis of the driving wheel 2, and the plurality of driven wheels are symmetrically arranged in pairs. Specifically, the number of the driven wheels is at least four;

[0034] The tooth pitch of each driven wheel can accommodate half the number of teeth of the driving wheel 2 when it is engaged with the driving wheel 2, and during the transmission process, the driving wheel 2 is engaged with two driven wheels at each moment (these two driven wheels are symmetrically arranged along the axis of the driving wheel 2), and at the same time, the driving wheel 2 and the other driven wheels are disengaged at this moment.

[0035] In this embodiment, it should be noted that the transmission mechanism can be applied to electric and other rotating mechanical structures. During the transmission process, the time for the driven wheel to disengage from the driving wheel 2 is very short each time. In the disengaged state, the driven wheel can continue to rotate by relying on its own inertia, thereby ensuring the stability of the transmission performance.

[0036] The technical effect achieved by this embodiment is: when the number of driven wheels is four, during the operation of the entire mechanism, the energy obtained by each driven wheel is approximately one-half of the energy of the driving wheel 2, while in the traditional one-to-four gear transmission mechanism, the energy obtained by each driven wheel is approximately one-quarter of the energy of its driving wheel. Compared with the traditional gear transmission mechanism, the energy-saving gear transmission mechanism can increase the energy obtained by multiple driven wheels without increasing the original power energy. At the same time, one driving wheel 2 drives multiple driven wheels, and each driven wheel can perform independent power output, which can save the number of power drive motors and reduce a large amount of power loss such as intermediate friction, thereby achieving a very obvious energy-saving effect.

[0037] Example 2

[0038] As shown in FIG. 1 to FIG. 8 , this embodiment provides another energy-saving gear transmission mechanism, the structure of which includes all the contents of embodiment 1, and only the different parts are described below.

[0039] In this embodiment, the driven wheels include a first driven wheel 3, a second driven wheel 4, a third driven wheel 5 and a fourth driven wheel 6. The first driven wheel 3 and the second driven wheel 4 are symmetrically arranged at the top and bottom of the driving wheel 2, respectively. The third driven wheel 5 and the fourth driven wheel 6 are symmetrically arranged on the left and right sides of the driving wheel 2, respectively.

[0040] During the transmission process, the first driven wheel 3 and the second driven wheel 4 are meshed with the driving wheel 2 at the same time each time, and the third driven wheel 5 and the fourth driven wheel 6 are meshed with the driving wheel 2 at the same time each time, and when the first driven wheel 3 and the second driven wheel 4 are meshed with the driving wheel 2, the third driven wheel 5 and the fourth driven wheel 6 are disengaged from the driving wheel 2; when the third driven wheel 5 and the fourth driven wheel 6 are meshed with the driving wheel 2, the first driven wheel 3 and the second driven wheel 4 are disengaged from the driving wheel 2;

[0041] Specifically, the operation process of the entire transmission mechanism is as follows: when the driving shaft 8 is driven to rotate by the driving mechanism, the driving shaft drives the driving wheel 2 to rotate. At the first moment, when the first driven wheel 3 and the second driven wheel 4 are engaged with the driving wheel 2, the third driven wheel 5 and the fourth driven wheel 6 are disengaged from the driving wheel 2; at the second moment, the third driven wheel 5 and the fourth driven wheel 6 are engaged with the driving wheel 2, and the first driven wheel 3 and the second driven wheel 4 are disengaged from the driving wheel 2; the two states of the first moment and the second moment are cyclically alternating, and the driving wheel 2 can drive each driven wheel to rotate continuously.

[0042] In this embodiment, it should be noted that the first driven shaft 9, the second driven shaft 10, the third driven shaft 11 and the fourth driven shaft 12 are further included, and the first driven shaft 9, the second driven shaft 10, the third driven shaft 11 and the fourth driven shaft 12 are all rotatably connected to the mounting bracket 1;

[0043] The first driven shaft 9 and the second driven shaft 10 are symmetrically arranged along the driving shaft 8, and the first driven shaft 9, the second driven shaft 10 and the driving shaft 8 are located in the same plane; the third driven shaft 11 and the fourth driven shaft 12 are symmetrically arranged along the driving shaft 8, and the third driven shaft 11, the fourth driven shaft 12 and the driving shaft 8 are located in the same plane;

[0044] The first driven wheel 3 is arranged on the first driven shaft 9 , the second driven wheel 4 is arranged on the second driven shaft 10 , the third driven wheel 5 is arranged on the third driven shaft 11 , and the fourth driven wheel 6 is arranged on the fourth driven shaft 12 .

[0045] The technical effects achieved by this embodiment are: the entire transmission mechanism structure is symmetrically arranged, the structure is more stable, and during operation, the transmission is smoother and more stable.

[0046] Example 3

[0047] As shown in FIG. 1 to FIG. 8 , this embodiment provides another energy-saving gear transmission mechanism, the structure of which includes all the contents of the embodiment 2, and only the different parts are described below.

[0048] In this embodiment, the driving wheel 2, the first driven wheel 3, the second driven wheel 4, the third driven wheel 5 and the fourth driven wheel 6 are all helical gears, and the helix angles of the first driven wheel 3, the second driven wheel 4, the third driven wheel 5 and the fourth driven wheel 6 are the same. The helix angle of the driving wheel 2 is the same as the helix angle of the first driven wheel 3, but the direction is opposite.

[0049] In this embodiment, it should be noted that the first driven wheel 3, the second driven wheel 4, the third driven wheel 5 and the fourth driven wheel 6 are all the same in shape, size and number of teeth. The number of teeth of the first driven wheel 3 is half of the number of teeth of the driving wheel 2. For example, when the number of teeth of the driving wheel 2 is 16, the number of teeth of the first driven wheel 3, the second driven wheel 4, the third driven wheel 5 and the fourth driven wheel 6 are all 8.

[0050] Furthermore, during operation, when the driving wheel 2 rotates - circle, the four driven wheels also rotate - circle at the same time. On the surface, it seems that one driving wheel is driving the four driven wheels to rotate, but in fact, at each instant, one driving wheel is driving the two driven wheels to rotate.

[0051] The technical effect achieved by this embodiment is that both the driving wheel 2 and the driven wheel are helical gears, and the stability and continuity during the transmission process are better.

[0053] As shown in FIG. 1 to FIG. 8 , this embodiment provides another energy-saving gear transmission mechanism, the structure of which includes all the contents of embodiment 1, and only the different parts are described below.

[0054] In this embodiment, a crank handle 7 is further included, which is arranged at the power input end of the driving shaft 8.

[0055] In this embodiment, it should be noted that the crank 7 and the driving shaft 8 are detachably connected. Specifically, the crank 7 and the driving shaft 8 are plugged into and fixed by a pin, and an anti-slip sleeve is provided on the handle of the crank 7.

[0056] The technical effects achieved by this embodiment are as follows: by providing a crank 8, power input can be performed by shaking the crank 8 during use; the crank 7 and the driving shaft 8 are detachably connected, and disassembly and assembly are convenient and quick.
