[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] When implementing: Figure 1-4As shown, a multi-roller power distribution gear reducer comprises: a shell 1, a multi-roller reduction transmission assembly 2 is fixedly connected to the inner wall of the shell 1; an adjustable output mechanism 4, an adjustable output mechanism 4 for increasing the output port of the multi-roller reduction transmission assembly 2 is arranged in the shell 1; wherein, the adjustable output mechanism 4 comprises a meshing speed change assembly 401 arranged in the shell 1, and a pushing meshing assembly 402 is provided on one side of the meshing speed change assembly 401. When used through this device, the multi-roller reduction transmission assembly 2 can be connected to the input motor, and then a plurality of rotating shafts with different speeds can be output through the multi-roller reduction transmission assembly 2, and then an additional rotating shaft can be output through the meshing speed change assembly 401. The pushing meshing assembly 402 can push the rotating shaft output by the meshing speed change assembly 401 to mesh with the rotating shafts of different speeds of the multi-roller reduction transmission assembly 2, and output different output speeds. While increasing the output speed, the speed fits the use requirements. Multiple different speeds can be output through the multi-roller reduction transmission assembly 2. For the staff in this technical field, the multi-roller reduction transmission assembly 2 is a prior art and will not be described in detail here.

[0023] like Figure 2 and Figure 3As shown, the synchronous output mechanism 3 includes a plurality of first output shafts 301 rotatably connected to the inner wall of the outer shell 1, and the surfaces of the multi-roller reduction transmission assembly 2 and the plurality of first output shafts 301 are fixedly connected with spur gears 302. The spur gears 302 on the surface of the multi-roller reduction transmission assembly 2 are meshed with the spur gears 302 on the surface of the first output shaft 301. The plurality of spur gears 302 are connected to the plurality of output rollers of the multi-roller reduction transmission assembly 2. When the multi-roller reduction transmission assembly 2 rotates, it drives the plurality of spur gears 302 to rotate. The plurality of spur gears 302 drive the plurality of first output shafts 301 to rotate through meshing, and output rotating rollers of multiple speeds outward. The meshing speed change assembly 401 includes a first rotating frame 4016 fixedly connected to the lower inner wall of the outer shell 1, and the inner wall of the first rotating frame 4016 is rotatably connected to the second output shaft 4015. The surface of the second output shaft 4015 is fixedly connected with a spline shaft 4013, and the surface of the spline shaft 4013 is fixedly connected with a spline sleeve 4014. The surface of the spline sleeve 4014 The first bevel gear 4011 is fixedly connected to the surface of the first output shaft 301, and the first bevel gear 4011 is fixedly connected to the surface of the first output shaft 301. The first bevel gear 4011 is meshed with the second bevel gear 4012. When the spline sleeve 4014 moves, the second bevel gear 4012 can be pushed to mesh with the two first bevel gears 4011 with different rotation speeds. At this time, the second bevel gear 4012 drives the second output shaft 4015 to rotate, which can achieve the output of different rotation speeds when pushing the meshing first bevel gears 4011 with different rotation speeds to meet the needs. The surface of the second output shaft 4015 is fixedly connected with two blocking sleeves 4017. The diameter of the blocking sleeve 4017 is larger than the diameter of the inner wall of the spline sleeve 4014. When the spline sleeve 4014 moves, it is easy to make the second bevel gear 4012 and the first bevel gear 4011 meshed and difficult to align. Through the abutment of the blocking sleeve 4017, the second bevel gear 4012 can be accurately meshed with the first bevel gear 4011, and it is not easy to misalign.

[0024] like Figure 3 and Figure 4As shown, the pushing engagement component 402 includes a pushing frame 4021 rotatably connected to the surface of the spline sleeve 4014, the upper end of the shell 1 is fixedly connected to a second rotating frame 4022, the inner wall of the second rotating frame 4022 is rotatably connected to a lead screw 4023, and the lead screw 4023 is threadedly connected to the inner wall of the pushing frame 4021. When the pushing engagement speed change component 401 is engaged, the lead screw 4023 can be rotated. At this time, the lead screw 4023 pushes the pushing frame 4021 to move, and the pushing frame 4021 drives the spline sleeve 4014 to move and engage. The inner wall of the shell 1 is fixedly connected to a limiting rod 4024, and one end of the limiting rod 4024 slides through the pushing frame 4021 and extends outward to engage with the outer The inner wall on the other side of the shell 1 is fixedly connected. When the pushing frame 4021 drives the spline sleeve 4014 to move, the pushing frame 4021 is prone to tilting. The sliding of the pushing frame 4021 is limited by the limiting rod 4024, so that the pushing frame 4021 is not prone to tilting when sliding. A worm gear self-locking component 4025 is fixedly connected to the upper end of the shell 1. The worm gear self-locking component 4025 is fixedly connected to the screw 4023. The screw 4023 can be self-locked by the worm gear self-locking component 4025 to prevent the screw 4023 from reversing and causing the engagement to loosen. For people working in this technical field, the worm gear self-locking component 4025 is a prior art and will not be elaborated on here.

[0025] When the utility model is in use, when it is used through this device, the multi-roller reduction transmission assembly 2 can be connected to the input motor. When the multi-roller reduction transmission assembly 2 rotates, it will drive the multiple spur gears 302 to rotate. The multiple spur gears 302 drive the multiple first output shafts 301 to rotate through engagement, and output rotating rollers of multiple speeds outward. At this time, the lead screw 4023 can be rotated. At this time, the lead screw 4023 pushes the pushing frame 4021 to move, and the pushing frame 4021 drives the spline sleeve 4014 to move and engage. When the spline sleeve 4014 moves, it can respectively push the second bevel gear 4012 to engage with the two first bevel gears 4011 with different speeds. At this time, the second bevel gear 4012 drives the second output shaft 4015 to rotate, and it can be achieved that when pushing the differently engaged first bevel gears 4011, different speeds are output outward to meet the needs of outputting different speeds.

[0026] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
