[0036] With reference to Figure 2 , Figure 5 and Figure 8The output end of the oil pump 17 is fixedly connected with a pipeline two 26, the outer part of the pipeline two 26 is fixedly connected with a ring pipe 27, the outer part of the ring pipe 27 is fixedly connected with a nozzle 28 on one side of the shell two 2, for conveying lubricating oil to the nozzle 28 to spray out, the input end of the oil pump 17 is fixedly connected with a pipeline one 24, one end of the pipeline one 24 is fixedly connected with an oil storage tank 25, the top of the oil storage tank 25 is fixedly connected to the bottom of the shell one 1, for extracting the lubricating oil in the oil storage tank 25.
[0037] Working principle: in the initial state, the teeth of the half gear one 13 are downward, when installing the shell one 1 and the shell two 2, first, install the speed reducer 10 and the rotating shaft 11 in the shell one 1, then place the shell two 2 on the shell one 1 (when placing, the shell two 2 is roughly aligned with the shell one 1), rotate the shell two 2 (at this time, the range of rotation is small), drive the blocking block 3 and the connecting rod 14 to rotate, make the blocking block 3 rotate to the lower part of the clamping block 7, make the threaded hole one 4 of the blocking block 3 and the threaded hole two 8 of the clamping block 7 align, at the same time, ensure that the connecting rod 14 outside the shell two 2 can keep the same horizontal line with the rotating shaft 11 after the gear two 15 rotates, then insert the bolt 9 into the sliding groove 5, and threadedly connect with the threaded hole one 4 and the threaded hole two 8, fix the threaded hole one 4 and the clamping block 7, so as to fix the shell one 1 and the shell two 2, at this time, the gear two 15 and the half gear one 13 are in meshing state, complete the assembly of the shell one 1 and the shell two 2 (after assembly, the shell one 1 and the shell two 2 are fixed, and do not rotate again), at this time, the two ends of the pipeline two 26 are connected with the ring pipe 27 and the oil pump 17, to avoid that the connecting rod 14 drives the pipeline two 26 to interfere with each other when the shell two 2 rotates; this assembly method is convenient for subsequent disassembly for maintenance or replacement of damaged shell one 1 or shell two 2.
[0038] When the speed reducer 10 operates, drive the rotating shaft 11 to rotate, when the rotating shaft 11 rotates, drive the half gear one 13 to rotate, make the half gear one 13 drive the gear two 15 to rotate through meshing, and the gear two 15 is rotatably connected to one end of the connecting rod 14, the other end of the connecting rod 14 is fixedly connected to the outside of the shell two 2, ensure that the gear two 15 can be stably rotated by the half gear one 13, when the gear two 15 rotates, drive the push rod 23 to rotate, because the number of teeth of the half gear one 13 is small, when the rotating shaft 11 rotates for many turns, the push rod 23 contacts the bottom of the push rod 19, at this time, the push rod 23 extrudes the push rod 19 to drive the push rod 19 to push the switch 22, the switch 22 extrudes the damper 21, at this time, the switch 22 controls the oil pump 17 to start operation.
[0039] When the half gear one 13 is engaged with the gear two 15 again, the push rod 19 is rotated to a certain angle by the push rod 19, at this time the push rod 19 loses the extrusion force of the push rod 19, and the push rod 19 no longer extrudes the switch 22, the switch 22 releases the extrusion of the damper 21, the damper 21 starts to rebound, and the switch 22 controls the oil pump 17 to stop starting, and the push rod 19 returns to the original position, waiting for the next time the push rod 23 contacts the push rod 19, and then repeating the above process; the oil pump 17 starts to extract the lubricating oil in the oil tank 25 through the pipeline one 24, and delivers it to the annular pipe 27 through the pipeline two 26, and sprays it out through the nozzle 28, lubricates the internal structure of the shell one 1 and the shell two 2, and circulates the lubricating oil during vehicle driving, so that the lubricating oil can uniformly cover all key structures, improve the lubricating effect, reduce the number of adding lubricating oil, and reduce the maintenance cost.
[0040] Finally, it should be noted that: the above only for the preferred embodiments of the utility model, and does not limit the utility model, although the utility model is described in detail with reference to the foregoing embodiments, for the person skilled in the art, it still can modify the technical scheme recorded in the foregoing each embodiment, or equivalent replacement to part of technical features, any modification, equivalent replacement, improvement etc. within the spirit and principles of the utility model, should be included in the protection scope of the utility model.
