However, during the use of the lubrication structure, the mounting positions of the lubrication structure and the planetary gear train are fixed, and the planetary gear train also needs to be installed on supporting equipment. At this time, the space of the supporting equipment is prone to spatial conflict with the lubrication structure, which affects the normal installation of the lubrication structure of the planetary gear train and causes the lubrication structure of the planetary gear train to be unusable.

[0019] The present invention will be further described below with reference to the accompanying drawings:

[0020] Example 1:

[0021] See also Figure 1-5: In this embodiment, a lubrication structure for a planetary gear system includes a first bracket 1 and a cylinder 4. The front of the first bracket 1 is fixedly connected to the rear end face of the cylinder 4. Multiple notches on the front of the first bracket 1 are respectively connected to a control structure 3. A nozzle 5 is inserted into the inner wall of the control structure 3. The model of the nozzle 5 is selected according to usage requirements. The front of the nozzle 5 is connected to an oil pipe 6. A sleeve 7 is fixed to the right side of the front of the first bracket 1, and the inner wall of the cylinder 4 is connected to the support structure 2.

[0022] The support structure 2 includes a screw 201 and a second bracket 202. The outer wall of the screw 201 is threadedly connected to the inner wall of the cylinder 4. The screw 201 is subjected to force and rotates back and forth through the inner wall of the cylinder 4. The front end of the outer wall of the screw 201 is rotationally connected to the inner wall of the second bracket 202. The screw 201 is subjected to force and rotates through the bearing on the inner wall of the second bracket 202. A handle 203 is fixed to the front face of the screw 201. The handle 203 facilitates the rotation of the screw 201. The notch on the right side of the front face of the second bracket 202 is connected to the outer wall of the oil pipe 6.

[0023] By holding the handle 203 in the support structure 2 and rotating it, the rotating handle 203 drives the screw 201 to rotate on the inner wall of the second bracket 202, and the screw 201 will gradually rotate toward the inner wall of the cylinder 4. At this time, the screw 201 will also drive the second bracket 202 to move backward, and the moving second bracket 202 will also change the position of the support bend of the oil pipe 6, thereby realizing the overall thickness of the lubrication structure of the planetary gear train, realizing space saving, avoiding the problem of space conflict, ensuring the normal installation of the lubrication structure of the planetary gear train, and ensuring the normal use of the lubrication structure of the planetary gear train.

[0024] The control structure 3 includes a straight cylinder 301 and a circular ring 302. The outer wall of the straight cylinder 301 is slidably connected to the inside of the front groove of the first bracket 1. The straight cylinder 30 is subjected to force and slides left and right through the inside of the front groove of the first bracket 1. The front of the outer wall of the straight cylinder 301 is threadedly connected to the inner wall of the circular ring 302. The circular ring 302 is subjected to force and rotates back and forth through the outer wall of the straight cylinder 301. The upper and lower sides of the circular ring 302 are respectively fixed with protrusions 303. The rear end face of the circular ring 302 is tightly pressed against the front of the first bracket 1, and the inner wall of the straight cylinder 301 is plugged into the outer wall of the nozzle 5.

[0025] Working principle:

[0026] Installation of lubrication structure of planetary gear train:

[0027] Make the outer side of the rear end face of the first bracket 1 meet the outer gear ring of the planetary gear train, then the bolt is threaded from the right front to the rear through the first bracket 1 and the outer gear ring of the planetary gear train to fix it, then make the ring 302 rotate forward through the thread of the outer wall of the straight cylinder 301, so that the ring 302 is separated from the front of the first bracket 1, then the straight cylinder 301 slides in the outer wall groove of the first bracket 1, so that the straight cylinder 301 is located above the meshing gear position of the planetary gear train, then the ring 302 is rotated backward in conjunction with the thread of the outer wall of the straight cylinder 301 , so that the rear end face of the ring 302 is pressed against the front face of the first bracket 1, friction is generated between the ring 302 and the first bracket 1, and the position of the straight cylinder 301 is fixed. Then the nozzle 5 is manipulated through the outer wall of the second bracket 202, so that the outer wall of the nozzle 5 is plugged into the inner wall of the straight cylinder 301 until the ridge position of the nozzle 5 fits with the front face of the straight cylinder 301. At this time, the oil pipe 6 is located in the groove of the outer wall of the second bracket 202, and the other end of the oil pipe 6 is connected to the lubricating oil tank, completing the installation of the lubrication structure of the planetary gear train.

[0028] Adjustment of spatial conflict of lubrication structure of planetary gear train:

[0029] Hold the handle 203 and rotate it. The rotating handle 203 drives the screw 201 to rotate on the inner wall of the second bracket 202. The screw 201 will gradually rotate toward the inner wall of the cylinder 4. At this time, the screw 201 will also drive the second bracket 202 to move backward. The moving second bracket 202 will also change the position of the support bend of the oil pipe 6, thereby realizing the overall thickness of the lubrication structure of the planetary gear system, realizing space saving, and avoiding the problem of space conflict.

[0030] The oil pipe 6 can deliver the lubricating oil to the position of the nozzle 5, and the nozzle 5 will spray the lubricating oil onto the meshing gears of the planetary gear train to achieve lubrication.

[0031] Example 2:

[0032] See also Figure 1-5 : In this embodiment, a lubrication structure for a planetary gear system further includes a straight rod 8, the front face of the straight rod 8 is fixedly connected to the rear end face of the second bracket 202, and the outer wall of the straight rod 8 is slidably connected to the inner wall of the sleeve 7.

[0033] Working principle:

[0034] When the second bracket 202 moves forward and backward, it will bring the straight rod 8 to slide forward and backward on the inner wall of the sleeve 7. The straight rod 8 restricts the second bracket 202 and prevents the second bracket 202 from rotating.

[0035] While the present invention has been shown and described with reference to preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
