[0056] 100 Gear ring assembly device. Detailed Implementation

[0057] First, it should be noted that the following description of the composition, features, and advantages of the gear ring assembly device according to the present invention will be given by way of example. However, it should be understood that all descriptions are given for illustrative purposes only and should not be construed as limiting the present invention in any way. In this document, the technical terms "first" and "second" are used only for distinguishing purposes and are not intended to indicate their order or relative importance. The technical term "connection (or linking, etc.)" covers the direct connection of a particular component to another component and / or indirect connection to another component. Furthermore, unless otherwise expressly specified and limited, the dimensions, directions, or positional relationships indicated by the technical terms "length," "width," "height," "upper," "top," "bottom," etc., are based on the dimensions, orientations, or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and for simplifying the description, and should not be construed as limiting the present invention.

[0058] Furthermore, for any single technical feature described or implied in the embodiments mentioned herein, or any single technical feature shown or implied in the accompanying drawings, the present invention still allows for any combination or deletion of these technical features (or their equivalents) without any technical obstacle, thereby obtaining more other embodiments of the invention that may not be directly mentioned herein. In addition, general matters known to those skilled in the art are not repeated herein.

[0059] Before assembly (e.g., before tightening the bolts on the gear ring), the gear ring in a car's engine or differential needs to be secured. The gear ring typically has 12-18 bolts, with a tightening torque of approximately 100-200 Nm. The differential gear ring bolt torque is relatively high, requiring a device to secure the gear ring before tightening the bolts. Different differentials have different gear ring sizes and tooth profiles; traditional gear ring securing devices need to be designed and manufactured specifically for each gear ring's dimensions, resulting in high costs and time-consuming and labor-intensive replacements.

[0060] In one embodiment of this application, a gear ring assembly device 100 is disclosed. For example... Figures 1a-1cAs shown, the gear ring assembly device includes a first mounting plate 8 and a second mounting plate 7, wherein the first mounting plate 8 is located above the second mounting plate 7, and the two are connected and fixed together by four mounting plate columns 6. A gear ring base 3 is provided on the first mounting plate 8, and the gear ring base 3 can be fixed to the first mounting plate 8 by multiple gear ring base bolts 16. The upper side of the gear ring base 3 has a protruding cylinder for placing and positioning the gear ring. Multiple support rods 1 are also provided on the first mounting plate 8 to support the gear ring. The embodiment shown in the figure includes four support rods 1; optionally, the number of support rods 1 can also be three or more, etc., to stably support the gear ring.

[0061] Optionally, multiple support rods 1 are evenly distributed circumferentially around the center of the gear ring base. For example, from... Figure 1c As can be seen in the top view, the four support rods 1 are distributed at 90° intervals around the center of the gear ring base 3. Each support rod 1 is attached to a corresponding track 9, which is a through slot penetrating the first mounting plate 8. The support rod 1 can be fixed to the track 9 by a support rod nut 23. The outer edge dimension of the support rod 1 can be larger than the slot width of the track 9. The lower part of the support rod 1 can have a threaded section passing through the track 9, which is screwed into the support rod nut 23 to fix the support rod 1 at a certain position on the track 9. Figure 1c In this embodiment, four tracks 9 extend radially outward from the center of the gear ring base 3, and corresponding to the support rod 1, the tracks 9 are evenly distributed circumferentially at 90° intervals with the center of the gear ring base as the center. Accordingly, the number of tracks 9 can be three or more, and the structure and dimensions of each track 9 can be identical. The gear ring base and support rod can provide support force to the gear ring in a direction parallel to the gear ring axis.

[0062] The device 100 of this application can be used to assemble gear rings of different sizes. Specifically, the position of the support rod 1 can be adjusted along the track 9 to support gear rings with different outer diameters. For example, when the assembled gear ring is small, each support rod 1 can be positioned close to the center of the gear ring base; when the assembled gear ring is large, the distance between the support rod 1 and the center of the gear ring base can be adjusted to be larger to match the size of the gear ring.

[0063] Optionally, the support height of the support rod 1 on the gear ring can also be adjusted to adapt to different working conditions. In this application, the support height can be understood as the distance between the upper end of the support rod 1 and the upper surface of the first mounting plate 8. For example, the support rod 1 can be a telescopic rod, or it can be a modular, splicing rod, where the support height of the support rod 1 can be adjusted by increasing or decreasing the number of splicing modules. These examples demonstrate that adjusting the longitudinal height of the support rod 1 using methods common in the art can achieve the purpose of adjusting its support height.

[0064] Furthermore, the assembly device for the gear ring of this application also includes a meshing base 4, which is disposed on the first mounting plate 8 and is used to place the meshing member 21 that meshes with the gear ring. The meshing member 21 has teeth that mate with the tooth profile of the gear ring 19, and engages and limits the movement of the gear ring in the circumferential direction during assembly. The meshing member 21 and the meshing base 4 are inserted into the first pin hole 2 on the meshing member 21 via a locating pin 14 (see...). Figure 3 The engagement element 21 is fixed together with the second pin hole 13 on the engagement base 4. It is understood that the engagement base 4 is detachably connected to the engagement element 21, which can be connected and separated by inserting and removing the positioning pin 14. This arrangement allows for the replacement of engagement elements 21 of different specifications to match the gear ring 19 for engagement and positioning. This arrangement also facilitates the assembly of gear rings of different specifications by the gear ring assembly device 100.

[0065] The engagement base 4 passes through the engagement fixing groove 11 on the first mounting plate 8 and can move within the engagement fixing groove 11. The engagement base 4 includes a base portion 41 and a threaded portion 15. The base portion 41 is located above the first mounting plate 8, and a first pin hole 2 can be provided on the base portion 41. The base portion 41 has a panel parallel to the first mounting plate 8, which covers the top of the engagement fixing groove 11. The threaded portion 15 is located below the first mounting plate 8. The threaded portion 15 has an internal thread, and the drive screw 12 passes through the threaded portion 15 and engages with the internal thread of the threaded portion 15. A rotating handle 5 is provided on the left side of the drive screw 12, which can be turned manually or mechanically to rotate the drive screw 12. By rotating the drive screw 12, the engagement base 4 can be driven along... Figure 1a The distance between the meshing member base 4 and the gear ring base 3 is adjusted by moving the meshing member base 4 to the left and right. When the gear ring assembly device 100 assembles gear rings of different specifications, such as gear rings with different outer diameters, the meshing member base 4 is driven to move to adjust the outer diameter position of the meshing member, thereby accommodating different sizes of gear rings. Furthermore, the axis of the meshing member base 4 (which coincides with the axis of the meshing member mounted on the meshing member base 4) extends along its moving path and intersects the axis of the gear ring base. In other words, the device 100 ensures that the extension of the meshing member (when placed on the meshing member base) along the moving path of the meshing member base 4 intersects the axis of the gear ring (when placed on the gear ring base).

[0066] Furthermore, the meshing base 4 can be fixedly connected to the first mounting plate 8 via meshing base bolts 17. Specifically, four through holes are provided at the four corners of the base portion 41 of the meshing base 4. The four meshing base bolts 17 pass through these through holes and the meshing guide grooves 22 on the first mounting plate 8, thereby tightening the meshing base 4, so that the meshing base 4 is fixedly connected to the first mounting plate 8, and then fixedly connected to the gear ring assembly device as a whole. By fixing the meshing base 4, the stability of the device 100 during the gear ring assembly process can be improved.

[0067] In some embodiments of this application, the second mounting plate 7 of the gear ring assembly device 100 is further provided with a plurality of second mounting plate fixing holes 18. The second mounting plate fixing holes 18 can fix the second mounting plate 7 to the ground or mounting platform, thereby fixing the entire gear ring assembly device 100 to maintain stability during gear ring assembly. When assembling the gear ring 19, the gear ring 19 is placed on the gear ring base 3 and supported by a plurality of support rods 1. It is engaged and limited in the circumferential direction by the meshing member 21. The upper part of the plurality of gear ring bolts 20 above the gear ring 19 is unobstructed, leaving sufficient assembly space. A multi-head torque gun can be used to assemble multiple gear ring bolts 20 at the same time, which improves assembly efficiency and reduces or avoids stress and deformation caused by not installing bolts at the same time.

[0068] As can be seen from the description in this application, the gear ring assembly device in this application has higher assembly efficiency and can assemble a wider range of gear ring specifications.

[0069] The specific embodiments described above are merely for the purpose of more clearly illustrating the principles of this application, wherein various components are clearly shown or described to make the principles of the invention easier to understand. Various modifications or variations can be easily made to this application by those skilled in the art without departing from the scope of this application. Therefore, it should be understood that all such modifications or variations should be included within the patent protection scope of this application.
