[0009] In an alternative embodiment, a linkage disk is fixed below the positioning ring. The linkage disk is sleeved on the outer walls of the positioning tubes and is linked with the locking members; Among them, when the driving sleeve rotates, it drives the positioning ring and the linkage disk to move downward synchronously, and the linkage disk drives each locking member to contract into the positioning tube.

[0010] In an alternative embodiment, a limiting ring is sleeved on the outer wall of the positioning tube, and the limiting ring is located above the linkage disk; A number of convex strips are circumferentially distributed on the upper circumference of the limiting ring for limiting the racks on the outer wall of the planetary gear.

[0013] In an alternative embodiment, an arc surface is arranged at the bottom wall of the outer end of the locking member, and the arc surface is adapted to abut against the upper end wall of the positioning tube; Among them, when the fixed column moves downward, the arc surface abuts against the upper end wall of the positioning tube, and the locking member contracts into the receiving groove.

[0014] In an alternative embodiment, an oil storage cavity is opened in the locking member, and an oil hole is opened on the outer wall of the locking member. The oil hole is communicated with the oil storage cavity; After the locking member retracts into the receiving groove, the fixing post moves downward, and the lubricating oil flows into the oil storage cavity. The positioning ring drives the outer gear ring to move upward, and the locking member synchronously extends outward until it abuts against the upper end wall of the planetary gear, and the lubricating oil in the oil storage cavity flows to the rack where the planetary gear meshes with the outer gear ring.

[0015] In an alternative embodiment, the driving sleeve is filled with lubricating oil, and a plurality of through holes are formed in the linkage disk. When the positioning ring drives the linkage disk to move downward, the lubricating oil flows through the through holes to the outer gear ring.

Through the cooperation of the retaining strip and the rack of the outer gear ring, after the outer gear ring is horizontally placed on the positioning ring, each retaining strip abuts against the two side walls and the tooth groove side wall of the rack of the outer gear ring to align the axis of the outer gear ring, thereby making the axis of the outer gear ring align with the axes of the planetary gears, avoiding the inclination of the outer gear ring during assembly. When the outer gear ring moves upward to mesh with the planetary gear, the locking member is adapted to limit the axial displacement of the planetary gear, preventing the axial movement of the planetary gear during assembly, and avoiding the tooth surface damage caused by the force offset of the planetary gear during the meshing process.

[0029] After research, it was found that in the related technology, when installing planetary gears, the planetary wheels are generally installed on the planetary carrier first, and then the outer ring gear is put on the planetary wheels; using the above installation method, when installing the outer ring gear, the outer ring gear needs to be engaged and matched with multiple planetary wheels at the same time; therefore, if the outer ring gear is tilted during installation, it will cause the outer ring gear to get stuck or cause tooth damage.

[0030] Therefore, how to prevent the outer gear ring from getting stuck when it is inserted into the planetary gear is a technical problem that needs to be solved urgently in this field.

[0031] The defects in the above solutions and the reasons for their occurrence are the results obtained by the inventor after practice and careful research. Therefore, the process of discovering the above problems and the solutions proposed by the present invention in this article for the above problems should be the contributions made by the inventor to the present invention during the disclosure process.

[0032] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it need not be aligned for further definition and explanation in subsequent drawings.

[0033] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0034] like Figures 1 to 8 As shown, at least one embodiment provides an EMB planetary gear assembly device, comprising: A workbench 1 is provided with an assembly device 3; a loading robot 2 is provided at one side of the assembly device 3 and is used to carry the planet carrier; after the outer gear ring 4 is meshed with each planetary gear, the loading robot 2 carries the planet carrier to the top of the assembly device 3 to realize the assembly of the star gear.

[0035] Reference Figure 2 The assembly device 3 comprises: a driving sleeve 31, which is rotatably arranged on the workbench 1; a driving motor is arranged on the bottom wall of the workbench 1, and the driving motor is in driving connection with the driving sleeve 31. Preferably, the driving sleeve 31 is rotatably sealed with the workbench 1, the driving sleeve 31 is filled with lubricating oil, and the linkage disk 35 is provided with a plurality of through holes 350; wherein, when the positioning ring 32 drives the linkage disk 35 to move downward, the lubricating oil flows to the outer gear ring 4 through the through holes 350. When the driving motor drives the driving sleeve 31 to rotate, the lubricating oil in the driving sleeve 31 will not flow outward.

[0036] Continue to refer to the attached Figure 2, a positioning ring 32, which is arranged to move up and down on the inner wall of the driving sleeve 31. A number of bumps 321 are circumferentially and uniformly distributed on the inner wall of the positioning ring 32. The bumps 321 are adapted to the racks of the external gear ring 4. That is, when the external gear ring 4 is horizontally placed on the positioning ring 32, one bump 321 corresponds to one rack on the inner side of the external gear ring 4. The arrangement of each retaining strip 322 further limits each rack to ensure the horizontality of the external gear ring 4 after being placed and prevent the external gear ring 4 from tilting. An internal thread 310 is provided on the inner wall of the driving sleeve 31. An external thread is provided on the outer wall of the positioning ring 32, and the internal thread 310 is in threaded engagement with the external thread.

[0037] Refer to the appendix again Figure 2 , a number of positioning tubes 33, which are arranged along the axial direction of the driving sleeve 31 and are used to position the planetary gears. The planetary gears are adapted to be sleeved on the outer wall of the positioning tubes 33. After the planetary gears are limited by the limiting ring 331, the upper ends of the star-shaped gears protrude from the positioning tubes 33, so as to facilitate the loading manipulator 2 to insert the planet carrier into the planetary gears. The bottom wall of the positioning tube 33 is fixed on the workbench 1. A number of locking members 34 are telescopically arranged in the positioning tubes 33. The locking members 34 are used to limit the axial displacement of the planetary gears. Among them, after the external gear ring 4 is horizontally placed on the positioning ring 32, the bumps 321 are matched with the racks of the external gear ring 4 to align the axis of the external gear ring 4 and prevent the external gear ring 4 from tilting during the placement process and the lifting and moving process. The driving motor drives the driving sleeve 31 to rotate circumferentially, and the driving sleeve 31 drives the positioning ring 32 to move up and down. The positioning ring 32 moves downward until the positioning tube 33 protrudes from the external gear ring 4, and each locking member 34 contracts into the positioning tube 33, and the planetary gears are sleeved on the outer wall of the positioning tube 33. At this time, each planetary gear is located above the external gear ring 4. The positioning ring 32 drives the external gear ring 4 to move upward, and the locking members 34 synchronously extend outward until they abut against the upper end wall of the planetary gears. During the meshing process of the external gear ring 4 and the planetary gears, the axis is maintained aligned through the bumps 321. The locking members 34 are adapted to limit the axial displacement of the planetary gears and prevent the planetary gears from axially moving during assembly, avoiding tooth surface damage of the star-shaped gears caused by force offset during the meshing process.

[0038] Refer to the appendix Figure 2 , a number of retaining strips 322 are arranged on both sides of the bump 321 and at the edge of the inner ring of the positioning ring 32. Among them, after the external gear ring 4 is horizontally placed on the positioning ring 32, the racks of the external gear ring 4 protrude from each bump 321. The retaining strips 322 are located below the external gear ring 4. When the external gear ring 4 moves upward to mesh with the planetary gears, the retaining strips 322 will not block the meshing of the external gear ring 4 and the planetary gears. A number of the retaining strips 322 are respectively in contact with the side walls of the racks and the side walls of the tooth grooves of the external gear ring 4 to align the axis of the external gear ring 4. The arrangement of a number of retaining strips 322 makes the axis of the external gear ring 4 aligned with the axes of each planetary gear, avoiding the tilting of the external gear ring 4 during assembly.

[0039] Refer to the appendix Figure 3, a linkage disk 35 is fixed below the positioning ring 32. The outer diameter of the linkage disk 35 is smaller than the inner diameter of the drive sleeve 31, and the linkage disk 35 is adapted to move up and down relative to the drive sleeve 31; the linkage disk 35 is sleeved on the outer walls of the positioning tubes 33, and the linkage disk 35 is adapted to move up and down relative to the positioning tubes 33 and is linked with the locking members 34; wherein, when the drive sleeve 31 rotates, it drives the positioning ring 32 and the linkage disk 35 to move downward synchronously, and the linkage disk 35 drives each locking member 34 to contract into the positioning tube 33. After each locking member 34 contracts into the positioning tube 33, at this time, each planetary gear is sleeved on the outer wall of the positioning tube 33. When the drive sleeve 31 rotates in the reverse direction, the positioning ring 32 drives the outer gear ring 4 to move upward, the linkage disk 35 moves upward synchronously, and each locking member 34 is pushed outward by the compression spring 371 until it abuts against the upper end wall of the planetary gear, so as to limit the planetary gear and prevent the axial movement of the planetary gear during assembly.

[0040] Continue to refer to the appendix Figure 3 , in order to improve the stability during the assembly of the star-shaped gear, a limiting ring 331 is sleeved on the outer wall of the positioning tube 33, and the limiting ring 331 is located above the linkage disk 35; the distance between the limiting ring 331 and the upper end wall of the positioning tube 33 is smaller than the axial length of the star-shaped gear. A plurality of convex strips 332 are circumferentially distributed on the limiting ring 331 for limiting the racks on the outer walls of the planetary gears. The setting of the convex strips 332, after each planetary gear is placed on the limiting ring 331, plays the role of limiting the planetary gear, not only preventing the rotation of the planetary gear during assembly, but also ensuring the alignment of the axes during the meshing process of the outer gear ring 4 and the planetary gear. Further, in order to facilitate the meshing of the outer gear ring 4 and the planetary gear, after the planetary gear is limited by the convex strips 332, the rack on the outer wall of the planetary gear closest to the outer gear ring 4 faces the tooth groove of the outer gear ring 4. When the outer gear ring 4 moves upward, the rack on the outer wall of the planetary gear can be inserted into the tooth groove on the inner wall of the outer gear ring 4 to ensure their mutual meshing.

[0041] Refer to the appendix Figure 3 , a fixing column 37 is arranged to move up and down in the positioning tube 33, and the upper end of the fixing column 37 protrudes from the positioning tube 33; a return spring 36 is arranged at the bottom of the fixing column 37, and the return spring 36 is arranged in the positioning tube 33, and the return spring 36 is adapted to push the fixing column 37 to move upward. When the positioning ring 32 drives the outer gear ring 4 to move upward, the return spring 36 pushes the fixing column 37 to move upward synchronously, so that the locking member 34 moves above the positioning tube 33. At this time, the compression spring 371 is adapted to push the locking member 34 to move outward to limit the planetary gear.

[0042] Continue to refer to the appendix Figure 3, two adjustment grooves 334 are symmetrically formed on the outer wall of the positioning tube 33 below the linkage disc 35; the adjustment grooves 334 are axially formed along the positioning tube 33, and the adjustment grooves 334 are located in the lubricating oil so that the positioning tube 33 is filled with lubricating oil. Extension blocks 335 are symmetrically arranged on the outer wall of the fixed column 37, and the extension blocks 335 are slidably arranged in the adjustment grooves 334; the extension blocks 335 protrude from the outer wall of the positioning tube 33; wherein, when the linkage disc 35 moves downward, the extension blocks 335 and the fixed column 37 are pushed to move downward synchronously. During the process of the fixed column 37 contracting into the positioning tube 33, the locking member 34 synchronously contracts into the receiving groove 370.

[0043] Reference appendix Figure 5 , two receiving grooves 370 are symmetrically formed in the fixed column 37 along the radial direction, and the locking member 34 is slidably arranged in the receiving grooves 370; a compression spring 371 is arranged in the receiving grooves 370, one end of the compression spring 371 abuts against the locking member 34, and the compression spring 371 is adapted to push the locking member 34 to slide outward and protrude from the outer wall of the fixed column 37.

[0044] Reference appendix Figure 4 , an arc surface 341 is arranged on the bottom wall of the outer end of the locking member 34, and the arc surface 341 is adapted to abut against the upper end wall of the positioning tube 33; wherein, when the fixed column 37 moves downward, the arc surface 341 abuts against the upper end wall of the positioning tube 33, and as the fixed column 37 continues to move downward, the positioning tube 33 presses the arc surface 341 so that the locking member 34 contracts into the receiving groove 370. At any time, the locking member 34 is immersed in the lubricating oil, and the lubricating oil flows into the oil storage cavity 342 through the oil hole 343.

[0045] Reference appendix Figure 5 , an oil storage cavity 342 is formed in the locking member 34, an oil hole 343 is formed in the outer wall of the locking member 34, and the oil hole 343 is communicated with the oil storage cavity 342; wherein, after the locking member 34 contracts into the receiving groove 370, the fixed column 37 moves downward, and the lubricating oil flows into the oil storage cavity 342; the positioning ring 32 drives the external gear ring 4 to move upward, and the locking member 34 synchronously extends outward to abut against the upper end wall of the planetary gear, and the lubricating oil in the oil storage cavity 342 flows to the rack where the planetary gear meshes with the external gear ring 4, further reducing the friction between the racks when the planetary gear meshes with the external gear ring 4.

[0046] Reference appendix Figure 6 and Figure 7 , after the external gear ring 4 is horizontally placed in the positioning ring 32, the positioning ring 32 drives it to move downward, and when the positioning ring 32 moves downward, it drives the linkage disc 35 to move downward synchronously, Figure 6In this, F1 indicates that the fixed column 37 moves downward, and F2 indicates that the locking member 34 moves into the receiving groove 370. The locking member 34 is pushed to move inward until it is completely retracted into the receiving groove 370. Figure 7 It represents the final stopping position of the fixed column 37. At this time, the locking member 34 is completely retracted into the receiving groove 370 and immersed in the lubricating oil.

[0047] At least one embodiment provides a working method of an EMB planetary gear assembly device. The working method includes: after the outer gear ring 4 is placed horizontally on the positioning ring 32, the convex block 321 matches the rack of the outer gear ring 4 to align the axis of the outer gear ring 4; the positioning ring 32 moves downward until the positioning tube 33 protrudes from the outer gear ring 4, and each locking member 34 retracts into the positioning tube 33, and the planetary gear is sleeved on the outer wall of the positioning tube 33; the positioning ring 32 drives the outer gear ring 4 to move upward, and the locking member 34 synchronously extends outward until it abuts against the upper end wall of the planetary gear. During the meshing of the outer gear ring 4 and the planetary gear, the axis alignment is maintained through the convex block 321.
