DETAILED DESCRIPTION
[0017] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.
[0018] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which the utility model belongs.
[0019] like Figures 1 to 3 As shown, a specific embodiment of the utility model provides a single-motor multi-end multi-speed output transmission device, which can use a single motor to drive two devices with different speed requirements to operate; specifically includes a frame 100, on which a motor unit (110) is provided, and also includes a transmission shaft 200, a first output shaft 300 and a second output shaft 400; one end of the transmission shaft 200 is provided with a first coupling 500 for connecting to the motor unit 110, and the other end of the transmission shaft 200 is transmission-connected to the first output shaft 300; the transmission shaft 200 is also provided with a bevel gear set 600, and the output end of the bevel gear is transmission-connected to the second output shaft 400 via a synchronous belt.
[0020] like Figures 1 to 3 As shown, through the above arrangement, the transmission device utilizes the transmission shaft 200 to connect with the output end of the motor unit 110, and the coupling is used to connect the transmission shaft 200 and the motor unit 110 to ensure the stability of the transmission. The coupling can ensure that the two shafts have a high degree of concentricity and a large torque transmission; the transmission shaft 200 and the first output shaft 300 and the second output shaft 400 form a transmission match, so that different devices can be driven to operate through the two output shaft structures. The first output shaft 300 is directly connected to the transmission shaft 200 to obtain the same speed output as the motor unit 110, and the second output shaft 400 is connected to the transmission shaft 200 through a bevel gear set 600. In production applications, the specifications and models of the motor unit 110 are selected according to actual needs, and the gear ratio data of the bevel gear set 600 is also adjusted according to equipment requirements. Different speed outputs are obtained, which is convenient for connecting two devices with different speed requirements. In this embodiment, the device is applied to spraying equipment as an example. The first output shaft 300 is used to drive the sprayer 1200, and the second output shaft 400 is used to drive the grinder 1300. Since the speed required by the grinder 1300 is twice the speed required by the sprayer 1200, the number of teeth on the active gear of the bevel gear set 600 is twice the number of teeth on the driven gear. Therefore, the two devices can obtain a speed that meets the requirements when they are running. When used for other equipment, the gear ratio of the bevel gear set 600 can be adjusted as needed. The transmission requirements of the two devices are integrated by the device, the repeated structure of the two machines is eliminated, the production cost can be reduced, and the overall layout of the machine can be reduced. The weight is further reduced, which is convenient for the large-scale transfer of equipment during decoration and use.
[0021] As mentioned above, the second output shaft 400 and the bevel gear set 600 are driven by a synchronous belt. In this embodiment, the driven gear of the bevel gear set 600 is connected with a driven shaft 800, and the driven shaft 800 and the end of the second output shaft 400 are provided with a synchronous pulley 700 for installing a synchronous belt. The synchronous belt drive method has the advantages of accurate transmission, no slip during operation, constant transmission ratio, stable transmission, buffering, vibration reduction, low noise, etc., and can work normally in places with relatively harsh working environments.
[0022] like Figures 1 to 3 As shown, since the transmission shaft 200 can directly drive the first output shaft 300 to rotate, the end of the transmission shaft 200 in this embodiment is connected to the first output shaft 300 through a rigid connector 1000. This allows the first output shaft 300 to obtain the same speed output as the motor unit 110; in order to ensure the stability of the connection between the second output shaft 400 and the device, a second coupling 1100 is also provided at the end of the second output shaft 400 in this embodiment.
[0023] like Figures 1 to 3 As shown, in order to facilitate the arrangement of different devices, the first output shaft 300 and the second output shaft 400 in this embodiment are arranged perpendicular to each other on a vertical plane, so that when installing the devices, different devices can be arranged separately to avoid interference.
[0024] like Figures 1 to 3 As shown, in order to improve the transmission stability, the present embodiment is provided with an inverted U-shaped transmission frame 900 for mounting the synchronous pulley 700 below the transmission shaft 200, and the transmission frame 900 is rotatably matched with the driven shaft 800 and the end of the second output shaft 400. The transmission frame 900 can be fixed on the frame 100, and the synchronous belt structure is mounted by the transmission frame 900 to ensure the transmission stability.
[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model, and they should all be included in the scope of the claims and specification of the utility model.
