[0014] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.
[0015] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.
[0016] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.
[0017] To illustrate the technical solution described in this application, specific embodiments are provided below.
[0018] Please see Figure 1 and Figure 2 As shown, the gearbox with multiple power interfaces provided in this application embodiment includes a connecting support 1, an input shaft 2, a first output shaft 3, and a second output shaft 4.
[0019] Input shaft 2 is used to mount a power source and transmit the power output from the power source. For example, the input end of input shaft 2 is provided with a spline for connecting to the power source of the host machine, so that power is input via input shaft 2.
[0020] Input shaft 2 is driven by first output shaft 3. For example, input shaft 2 and first output shaft 3 are driven by a two-stage cylindrical gear pair. First output shaft 3 is used to output first power. Optionally, first output shaft 3 and input shaft 2 are arranged horizontally.
[0021] The output end of the second output shaft 4 is provided with a rectangular spline for outputting a second power. Specifically, the input shaft 2 and the second output shaft 4 are connected by a first pair of bevel gears, and the second output shaft 4 is used to output the second power through the rectangular spline.
[0022] The connecting support 1 is equipped with a second pair of bevel gears that are connected to the input shaft 2 for transmission. The end of the driven bevel gear of the second pair of bevel gears is provided with an involute internal spline 5, which is used to output the third power.
[0023] The working principle of the multi-power interface gearbox provided in this application embodiment is as follows: the power source inputs power to the gearbox through input shaft 2, and the gearbox can output power through the following three paths: (1) After passing through the gear transmission mechanism inside the gearbox, the first output shaft 3 outputs the first power, the rectangular spline of the second output shaft 4 outputs the second power, and the involute inner spline 5 outputs the third power.
[0024] (2) For example, the gear transmission mechanism includes a two-stage cylindrical gear pair. The input shaft 2 is connected to the first output shaft 3 through the two-stage cylindrical gear pair to output the first power.
[0025] (3) The gear transmission mechanism also includes a first pair of bevel gears. The input shaft 2 transmits torque to the second output shaft 4 through the first pair of bevel gears. The second output shaft 4 outputs the second power through the rectangular spline connected to it.
[0026] (4) The gear transmission mechanism also includes a second pair of bevel gears. The input shaft 2 transmits torque to the driven bevel gear of the second pair of bevel gears through the second pair of bevel gears. The driven bevel gear outputs the third power through the involute internal spline 5 at its end.
[0027] (5) As an optional method, the first pair of bevel gears and the second pair of bevel gears share the driving bevel gear.
[0028] The aforementioned multi-power-interface gearbox can achieve a "one-in, three-out" power transfer function, meaning that the power input of the main unit can be output from three interfaces in various forms, which is conducive to the diversified expansion of the main unit's functions and improves the product performance of the main unit.
[0029] In some embodiments of this application, the first output shaft 3 is connected and driven by a two-stage cylindrical gear pair, and the transmission ratio can be adjusted according to the operating conditions. The transmission ratio of the two pairs of bevel gear pairs can also be adjusted according to the operating conditions. When the driving bevel gear is shared, the transmission ratio of the second output shaft 4 and the involute internal spline 5 is the same. In this way, with "one input and three outputs", the output can obtain power with different speeds and torques, which can meet diverse power needs, and the structure is simple and the cost is low.
[0030] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be included within the protection scope of this application.
