when the second rotating rod 75 rotates, two driving bevel gears 76 can be driven to rotate together, at this time, the driving bevel gears 76 can drive driven bevel gears 77 meshed with one side to rotate together, when the driven bevel gears 77 rotate, the first rotating rod 45 can be driven to rotate, therefore, the first rotating rod 45 can drive the turbine 44 connected with the bottom end to start rotating, when the turbine 44 rotates, the pump body 43 can drive the cooling pipe 42 and the liquid inside the heat conducting pipe 41 to flow, when the liquid flows inside the heat conducting pipe 41, the temperature of the surface of the speed reducer body 2 can be taken away, and when the liquid flows inside the cooling pipe 42, the cooling fan 32 can blow cold air to the cooling pipe 42, and because the cooling pipe 42 is of an S-shaped structure, the flowing time of the liquid inside the cooling pipe 42 is long, and the cooling pipe has a certain time to start cooling the liquid; finally, the cooling pipe 42 and the heat conducting pipe 41 can be used for avoiding that the internal temperature is increased due to lower air density when the speed reducer body 2 is in operation, so that the internal lubricating oil function is affected, and finally, the cooling mechanism 4 can improve the operation stability of the speed reducer body 2.
The application method and the working principle of the device are as follows: when the speed reducer body 2 is in normal operation, the driving motor 74 also starts to operate, and when the driving motor 74 is in operation, the driving wheel 71 can be driven to rotate, and at the moment, the driving wheel 71 can be driven to rotate together with the driven wheel 73 by using the synchronous belt 72, so that when the driven wheel 73 rotates, the second rotating rod 75 can be driven to start to rotate, and when the second rotating rod 75 rotates, the disc 62 connected with one end can be driven to start to rotate.
When the disc 62 starts to rotate, the push rod 621 located at the edge of the surface of the disc 62 can be driven to start to do circular motion, and because the push rod 621 is located in the movable groove 632 on the surface of the swinging rod 63, the movable groove 632 is used for driving the swinging rod 63 to move when the push rod 621 does circular motion, and because one end of the swinging rod 63 is rotationally connected with the rotating shaft 631, the rotating shaft 631 is used as a circle center when the swinging rod 63 swings, and finally, along with the continuous rotation of the disc 62, the push rod 621 is used for driving the swinging rod 63 to do left-right swinging motion taking the rotating shaft 631 as the circle center all the time; then, along with the swinging of the swinging rod 63, the second limiting groove 633 at the other end of the swinging rod 63 exists, the other end of the swinging rod 63 drives the second limiting rod 661 to move, so that the second limiting rod 661 can reciprocate left and right, and the movable plate 65 connected with one end of the second limiting rod 661 also moves left and right continuously due to the continuous movement of the second limiting rod 661, so that when the movable plate 65 moves continuously, the movable plate 65 also moves together with the rack 66, and further, the rack 66 drives the gear teeth 521 to move in the moving process due to the continuous movement of the rack 66 left and right, so that the rotating disc 52 starts to rotate clockwise and anticlockwise alternately when rotating.
Then, along with the rotation of the rotating disc 52, the linkage rod 53 on the surface is driven to move together, at this time, when the linkage rod 53 further drives the positioning block 54 to move together, because one end of the positioning block 54 is rotationally connected with the middle plate 56, along with the driving of the linkage rod 53, the other end of the positioning block 54 is driven to move, so that the other end of the positioning block 54 moves close to the output shaft 1; because the first limiting groove 522 on the surface of the rotating disc 52 moves relative to the first limiting rod 523 in the rotating process, when the rotating disc 52 rotates, the rotating angle of the rotating disc 52 is limited by the radian of the first limiting groove 522, so that the positioning block 54 can only move within a certain range when the linkage rod 53 is used for driving the positioning block 54 to move, and when the rotating disc 52 simultaneously uses a plurality of linkage rods 53 for driving a plurality of positioning blocks 54 to move together, the plurality of positioning blocks 54 can be folded, and the positioning of the output shaft 1 is completed.
Finally, due to the rotation of the disc 62, the rotating disc 52 also rotates clockwise and counterclockwise alternately, so that the positioning blocks 54 perform folding and unfolding alternately; in this process, if the output shaft 1 does not deviate, the motion of the positioning block 54 does not interfere with the normal rotation of the output shaft 1, and only when the output shaft 1 deviates, the plurality of positioning blocks 54 apply an acting force to the deviated output shaft 1 in the motion process, and under the action, the output shaft 1 resets after the deviation.
Although the present invention has been described with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described, or equivalents may be substituted for elements thereof, and any modifications, equivalents, improvements and changes may be made without departing from the spirit and principles of the present invention.
