Description

Technical Field

[0001] This invention relates to the technical field of automotive drive assemblies, and more particularly to a bearing tooling, a bearing mounting assembly, and a bearing mounting method. Background Technology

[0002] The housing of a car's drivetrain includes a main housing and a secondary housing. The main housing houses most of the drivetrain components, while the secondary housing contains bearing chambers for mounting the bearings of the shaft system. To prevent the bearings from detaching from or shifting from the bearing chambers, the current practice is to use a bearing clamp to hold the bearings in place within the bearing chambers. The bearing clamp is connected to the secondary housing by multiple bolts.

[0003] Due to the shaft arrangement and assembly sequence, the bearing pressure plate needs to be installed and locked from the outside of the housing after the bearing housing and main housing are assembled. The conventional practice is to blindly install it manually in a small space during assembly, adjusting the angle of the bearing pressure plate while pre-tightening the bolts. This installation method is difficult and inefficient.

[0004] Therefore, it is necessary to design a bearing fixture, bearing mounting assembly, and bearing installation method that ensures the bearing pressure plate is locked from the outside, facilitates installation, and improves installation efficiency. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a bearing fixture, bearing installation assembly, and bearing installation method that ensures the bearing pressure plate is locked from the outside, facilitates installation, and improves installation efficiency.

[0006] The technical solution of the present invention provides a bearing fixture, including multiple bearing pressure plates, each of the bearing pressure plates being provided with a first bolt hole, and the bearing fixture further including a pressure plate positioning seat;

[0007] The pressure plate positioning seat is provided with a plurality of spaced pressure plate positioning grooves. When each of the bearing pressure plates is embedded in one of the pressure plate positioning grooves, the plurality of bearing pressure plates are in the open position.

[0008] The bearing pressure plate is also provided with a positioning element. When the bearing pressure plate is connected to the bearing mounting seat for installing the bearing, the positioning element is used to position the bearing mounting seat.

[0009] Furthermore, the pressure plate positioning seat is also provided with a plurality of positioning bosses, which are used to position with the bearing mounting seat so that the first bolt hole is aligned with the bolt on the bearing mounting seat.

[0010] Furthermore, the bearing fixture also includes a clamping plate, which is disposed in the middle of the pressure plate positioning seat and is rotatably connected to the pressure plate positioning seat. A pressure strip extends from the clamping plate toward the pressure plate positioning groove, and the pressure strip is used to press the bearing pressure plate into the pressure plate positioning groove.

[0011] The present invention also provides a bearing mounting assembly, including a bearing mounting base, and further including the bearing tooling described in any of the above claims.

[0012] Furthermore, the bearing mounting base includes a raised mounting ring, the interior of which is used to mount the bearing. The mounting ring has a plurality of spaced second bolt holes, which are aligned with the first bolt holes and connected by bolts.

[0013] Furthermore, the outer edge of the mounting ring is provided with a plurality of limiting bosses, which are used to cooperate with the positioning component.

[0014] Furthermore, a limiting surface is provided on the outer edge of the mounting ring. When the positioning member separates from the limiting boss, the bearing pressure plate rotates to contact the limiting surface and is in a stop position. In the stop position, the bearing pressure plate is used to stop the bearing.

[0015] The present invention also provides a bearing mounting method using the bearing mounting assembly described in any one of the above claims, characterized by comprising the following steps:

[0016] The bearing pressure plate is installed on the pressure plate positioning seat, and the multiple bearing pressure plates are in the open position;

[0017] The pressure plate positioning seat and the bearing pressure plate are installed together on the bearing mounting seat. The positioning element is positioned with the bearing mounting seat, and the bearing pressure plate is connected to the bearing mounting seat by tightening the bolts, so that the bearing pressure plate is kept in the open position.

[0018] The pressure plate positioning seat is separated from the bearing pressure plate;

[0019] Install the bearing into the bearing mounting base;

[0020] Loosen the bolts, and the positioning element separates from the bearing mounting seat;

[0021] Tighten the bolt, and the bolt will cause the bearing pressure plate to rotate to the stop position, and the bearing pressure plate will stop the bearing;

[0022] Tighten the bolts.

[0023] Furthermore, the outer edge of the mounting ring is provided with multiple limiting bosses. When the positioning member abuts against the limiting bosses, the bolt can fasten the bearing pressure plate and the bearing mounting seat.

[0024] When the bolt is loosened, the positioning member separates from the limiting boss.

[0025] Furthermore, a limiting surface is provided on the outer edge of the mounting ring. When the positioning member separates from the limiting boss, the bearing pressure plate rotates to contact the limiting surface, and the bearing pressure plate is in the stop position. The above technical solution has the following beneficial effects:

[0026] This invention uses a positioning seat to position the bearing pressure plate in the open position. After the bearing pressure plate is connected to the bearing mounting seat, tightening the bolts secures the bearing pressure plate to the bearing mounting seat, thus maintaining the bearing pressure plate in the open position. Then, loosening the bolts separates the positioning element from the bearing mounting seat. Tightening the bolts again, due to the separation of the positioning element from the bearing mounting seat, allows the bolts to rotate the bearing pressure plate, causing it to rotate to the stop position, thus acting as a bearing stop. Finally, the bolts are locked. This invention allows the bearing pressure plate to be positioned in the open position before installation, and after installation, the bearing pressure plate can be switched to the stop position by adjusting the bolts. This ensures precise positioning of the bearing pressure plate and the bearing housing, facilitating installation and improving installation efficiency. Attached Figure Description

[0049] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0050] It is readily understood that, based on the technical solution of this invention, various structural and implementation methods can be interchanged by those skilled in the art without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of the invention.

[0051] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the structures shown in the accompanying drawings. They are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0052] Example 1:

[0053] like Figure 1-Figure 2 As shown, the bearing fixture includes multiple bearing pressure plates 1, each bearing pressure plate 1 is provided with a first bolt hole 11, and the bearing fixture also includes a pressure plate positioning seat 2.

[0054] The pressure plate positioning seat 2 is provided with multiple spaced pressure plate positioning grooves 21. When each bearing pressure plate 1 is embedded in one of the pressure plate positioning grooves 21, the multiple bearing pressure plates 1 are in the open position.

[0055] The bearing pressure plate 1 is also provided with a positioning element 12. When the bearing pressure plate 1 is connected to the bearing mounting seat 4 for installing the bearing, the positioning element 12 is used to position the bearing mounting seat 4.

[0056] Specifically, such as Figure 1 As shown, the housing of the drive assembly includes a main housing 20 and a secondary housing 30. A bearing mounting seat 4 is provided on the inner side of the secondary housing 30. The bearing 10 needs to be installed in the bearing mounting seat 4. The bearing pressure plate 1 is connected to the bearing mounting seat 4 by bolts 5 and restricts the axial displacement of the bearing 10 to prevent the bearing 10 from coming out of the bearing mounting seat 4.

[0057] like Figure 2 As shown, in this embodiment, there are three bearing pressure plates 1. The bearing pressure plates 1 are crescent-shaped and have a first bolt hole 11 and a positioning element 12. The first bolt hole 11 is a through hole for installing bolts 5. The positioning element 12 is cylindrical and protrudes from the body of the bearing pressure plate 1. Preferably, the positioning element 12 can be a positioning pin or other positioning structure.

[0058] The pressure plate positioning seat 2 is disc-shaped and has three pressure plate positioning grooves 21. The shape of the pressure plate positioning grooves 21 corresponds to part of the outer contour of the bearing pressure plate 1, so that the bearing pressure plate 1 can be perfectly embedded in the pressure plate positioning grooves 21. After the three bearing pressure plates 1 are installed in the pressure plate positioning seat 2, they are in the open position. Here, "open position" refers to the position of the bearing pressure plates 1. When they are used with the bearing 10, they will not interfere with the bearing 10, which facilitates the installation of the bearing 10 into the bearing mounting seat 4.

[0059] The positioning element 12 serves to position the bearing plate 1 when it comes into contact with the bearing mounting base 4, allowing the bearing pressure plate 1 to be tightened with the bearing mounting base 4 via bolts 5 and held in the open position. Thus, even after the pressure plate positioning seat 2 separates from the bearing pressure plate 1, all three bearing pressure plates 1 remain in the open position, facilitating the installation of the bearing 10 into the bearing mounting base 4.

[0060] like Figure 4 As shown, the pressure plate positioning seat 2 plays the role of initially positioning the bearing pressure plate 1, and then assists the bearing pressure plate 1 in connecting with the bearing mounting seat 4.

[0061] like Figure 6 As shown, after the bearing pressure plate 1 is connected to the bearing mounting seat 4 by bolts 5, the pressure plate positioning seat 2 separates from the bearing pressure plate 1.

[0062] like Figure 7 As shown, the positioning piece 12 abuts against the limiting boss 43 on the bearing mounting seat 4. At this time, the bolt 5 is tightened, which securely connects the bearing pressure plate 1 and the bearing mounting seat 4, thus keeping the bearing pressure plate 1 in the open state.

[0063] like Figure 9 As shown, the bearing 10 is installed axially into the bearing mounting base 4, at which time the bearing pressure plate 1 does not interfere with the bearing 10.

[0064] like Figure 11 As shown, after loosening bolt 5, the positioning part 12 is separated from the limiting boss 43, and the bearing pressure plate 1 is not restricted from rotating.

[0065] like Figure 12 As shown, tighten bolt 5 again. During the rotation of bolt 5, the bearing pressure plate 1 will rotate together, causing the bearing pressure plate 1 to rotate around the central axis of bolt 5. Figure 12 Rotating clockwise causes the bearing pressure plate 1 to rotate to the inside of the bearing 10.

[0066] like Figure 14 As shown, continue to tighten bolts 5 until bearing pressure plate 1 contacts bearing 10 and restricts bearing 10 in bearing mounting seat 4. At this time, the three bearing pressure plates 1 are in the stop position.

[0067] This embodiment can position the bearing pressure plate 1 in the open position before installation, and after installation, the bearing pressure plate 1 can be switched from the open position to the stop position by adjusting the bolt 5, which ensures the accurate positioning of the bearing pressure plate 1 and the bearing mounting seat 4, facilitates installation, and improves installation efficiency.

[0068] Furthermore, such as Figure 2 As shown, the pressure plate positioning seat 2 is also provided with multiple positioning bosses 22. The positioning bosses 22 are used to position with the bearing mounting seat 4 so that the first bolt hole 11 is aligned with the bolt 5 on the bearing mounting seat 4.

[0069] Specifically, such as Figure 2 As shown, the positioning boss 22 protrudes from the body of the pressure plate positioning seat 2. There are also three positioning bosses 22, which are located between adjacent pressure plate positioning grooves 21. The positioning bosses 22 are arc-shaped and located on the outer edge of the pressure plate positioning seat 2.

[0070] like Figure 4 As shown, when the pressure plate positioning seat 2 and the bearing pressure plate 1 are installed together on the bearing mounting seat 4, the positioning boss 22 contacts the angular positioning surface 45 on the bearing mounting seat 4.

[0071] like Figure 5 As shown, in this embodiment, the angular positioning surface 45 is located on the side of the limiting boss 43. When the side of the positioning boss 22 abuts against the angular positioning surface 45, the three positioning bosses 22 surround the periphery of the bearing mounting base 4, and the first bolt hole 11 on the bearing pressure plate 1 is aligned with the second bolt hole 42 on the bearing mounting base 4. The bolt 5 can pass through the second bolt hole 42 and the first bolt hole 11 from the outside of the housing 30, thereby connecting the bearing pressure plate 1 to the bearing mounting base 4.

[0072] Optionally, the angular positioning surface 45 can also be set at other positions of the bearing mounting base 4, and can be set separately from the limiting boss 43.

[0073] Furthermore, such as Figure 2-Figure 3 As shown, the bearing fixture also includes a clamping plate 3, which is disposed in the middle of the pressure plate positioning seat 2 and is rotatably connected to the pressure plate positioning seat 2. The clamping plate 3 extends a pressure strip 31 toward the pressure plate positioning groove 21.

[0074] The pressure bar 31 is used to press the bearing pressure plate 1 into the pressure plate positioning groove 21.

[0075] Specifically, such as Figure 2 As shown, the center of the clamping plate 3 is disc-shaped, and the clamping plate 3 is coaxially and rotatably connected to the pressure plate positioning seat 2. Three pressure strips 31 extend radially from the clamping plate 3. When the bearing pressure plate 1 is installed, the pressure strips 31 of the clamping plate 3 do not interfere with the bearing pressure plate 1.

[0076] like Figure 3 As shown, after the bearing pressure plate 1 is embedded in the pressure plate positioning groove 21, the pressure plate 3 is rotated so that the pressure strip 31 contacts the bearing pressure plate 1. The pressure strip 31 presses the bearing pressure plate 1 in the axial and circumferential directions to prevent the bearing pressure plate 1 from separating from the pressure plate positioning seat 2.

[0077] Preferably, such as Figure 3 As shown, the edge of the first bolt hole 11 is provided with a protruding ring 13 that protrudes from the bearing pressure plate 1. When the pressure plate 3 rotates, the pressure strip 31 contacts the protruding ring 13, and the protruding ring 13 plays the role of limiting the pressure strip 31. At this time, the pressure strip 31 rotates to the position that presses the bearing pressure plate 1.

[0078] like Figure 7 As shown, the convex ring 13 can mate with the second bolt hole 42 on the bearing mounting base 4, serving as a guide and rotation centering function.

[0079] The bearing fixture in this embodiment can pre-position the bearing pressure plate 1, ensuring both the positioning of the bearing pressure plate 1 when connected to the bearing mounting base 4 and keeping the bearing pressure plate 1 in the open position. By adjusting the bolt 5, the bearing pressure plate 1 can be switched from the open position to the stop position, thereby limiting the movement of the bearing 10. In this embodiment, the bearing pressure plate 1 and the bearing mounting base 4 can be accurately positioned, making installation more convenient and improving installation efficiency.

[0080] Example 2:

[0081] like Figure 5 As shown, the bearing mounting assembly includes a bearing mounting base 4 and a bearing tooling as described above.

[0082] Specifically, the bearing mounting base 4 includes a raised mounting ring 41, the interior of which is used to mount the bearing 10. The mounting ring 41 is provided with a plurality of spaced second bolt holes 42, which are aligned with the first bolt holes 11 and connected by bolts 5.

[0083] The mounting ring 41 is annular, and the bearing 10 is installed inside the mounting ring 41. The mounting ring 41 has three second bolt holes 42 spaced apart, and the positions of the second bolt holes 42 protrude outward from the center to form a convex circular surface 46.

[0084] Furthermore, such as Figure 5 As shown, the outer edge of the mounting ring 41 is provided with multiple limiting bosses 43, which are used to cooperate with the positioning member 12.

[0085] Specifically, such as Figure 5 As shown, the limiting boss 43 is located near the second bolt hole 42 and is located on one side of the convex surface 46. The top surface of the limiting boss 43 is lower than the top surface of the mounting ring 41.

[0086] like Figure 7 As shown, when the bearing pressure plate 1 is in the open position and connected to the bearing mounting base 4, the positioning member 12 is in contact with the top surface of the limiting boss 43, and the axial clearance between the positioning member 12 and the top surface of the limiting boss is b, at which time b = 0. The distance between the bearing pressure plate 1 and the top surface of the mounting ring 41 is a, at which time a > 2 mm.

[0087] Due to the cooperation between the limiting boss 43 and the positioning member 12, the bolt 5 can fasten the bearing pressure plate 1 to the bearing mounting seat 4, thereby keeping the multiple bearing pressure plates 1 in the open position and preventing the bearing pressure plates 1 from rotating.

[0088] Furthermore, such as Figure 5 and Figure 13 As shown, a limiting surface 44 is also provided on the outer edge of the mounting ring 41. When the positioning member 12 separates from the limiting boss 43, the bearing pressure plate 1 rotates to contact the limiting surface 44 and the bearing pressure plate 1 is in the stop position. When in the stop position, the bearing pressure plate 1 is used to stop the bearing 10.

[0089] Specifically, the limiting surface 44 is located on the other side of the convex surface 46 on which the second bolt hole 42 is installed, and the limiting surface 44 and the limiting boss 43 are located on both sides of the convex surface 46.

[0090] When the bearing pressure plate 1 rotates, the positioning member 12 rotates together with the bearing pressure plate 1. When the positioning member 12 passes around the convex surface 46 and moves to contact the limiting surface 44, it is restricted by the limiting surface 44 and the bearing pressure plate 1 cannot continue to rotate. At this time, the bearing pressure plate 1 is exactly in the stop position.

[0091] In this embodiment, by setting the bearing mounting seat 4, the positioning and limiting of the bearing pressure plate 1 are achieved, thereby realizing the installation positioning, opening position positioning and stopping position limiting of the bearing pressure plate 1.

[0092] Example 3:

[0093] The bearing mounting method for the bearing mounting assembly includes the following steps:

[0094] like Figure 2 As shown, the bearing pressure plate 1 is installed on the pressure plate positioning seat 2, and multiple bearing pressure plates 1 are in the open position;

[0095] like Figure 4 As shown, the pressure plate positioning seat 2 and the bearing pressure plate 1 are installed together onto the bearing mounting seat 4, as follows. Figure 7 As shown, the positioning piece 12 is positioned with the limiting boss 43 of the bearing mounting seat 4, and the bearing pressure plate 1 and the bearing mounting seat 4 are connected by tightening the bolt 5, so that the bearing pressure plate 1 is kept in the open position.

[0096] like Figure 6 As shown, the pressure plate positioning seat 2 is separated from the bearing pressure plate 1;

[0097] like Figure 9 As shown, the bearing 10 is installed into the bearing mounting base 4, as follows. Figure 10 As shown, after the bearing 10 is installed, the bearing 10 is higher than the top surface of the mounting ring 41, and the gap between the bearing 10 and the top surface of the mounting ring 41 is c, where 0mm < c ≤ 1mm.

[0098] like Figure 11 As shown, loosen bolt 5, and the positioning part 12 separates from the bearing mounting seat 4. At this time, 0mm < b < 4mm.

[0099] like Figure 12 As shown, tighten bolt 5 again, and bolt 5 will cause the bearing pressure plate 1 to rotate to the stop position;

[0100] like Figure 14 As shown, locking bolt 5 and bearing pressure plate 1 stop bearing 10. At this time, ac = 0, and bearing pressure plate 1 and bearing 10 are pressed together. Figure 13 As shown, at this time, the positioning element 12 is in contact with the limiting surface 44, which restricts the bearing pressure plate 1 from rotating further.

[0101] This invention uses a positioning seat to position the bearing pressure plate in the open position. After the bearing pressure plate is connected to the bearing mounting seat, tightening the bearing pressure plate to the bearing mounting seat keeps it in the open position. Then, loosening the bolts separates the positioning element from the bearing mounting seat. Tightening the bolts, due to the separation of the positioning element from the bearing mounting seat, allows the bolts to rotate the bearing pressure plate, causing it to rotate to the stop position, thus acting as a bearing stop. Finally, the bolts are locked. This invention allows the bearing pressure plate to be positioned in the open position before installation, and after installation, the bearing pressure plate can be switched to the stop position by adjusting the bolts. This ensures precise positioning of the bearing pressure plate from the housing, facilitating installation and improving installation efficiency.

[0102] The above description is merely the principle and preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several other modifications can be made based on the principle of the present invention, and these modifications should also be considered within the scope of protection of the present invention.
