Technical Field

[0001] The invention relates to the technical field of automobile drive assemblies, and in particular to a bearing tool, a bearing mounting assembly and a bearing mounting method. Background Art

[0002] The housing of the drive assembly of the automobile includes a main housing and a separate housing. The main housing is used to install most of the components of the drive assembly. The separate housing is provided with a bearing chamber, which is used to install the bearing of the shaft system. In order to prevent the bearing from being separated or shifted from the bearing chamber, the existing practice is to use a bearing pressure plate to press the bearing in the bearing chamber, and the bearing pressure plate is connected to the separate 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 housing is assembled with the main housing. The conventional practice is to blindly install the bearing pressure plate in a small space by manual operation during assembly, while adjusting the angle of the bearing pressure plate and pre-tightening the bolts. This installation method is difficult to operate and has low efficiency.

[0004] Therefore, it is necessary to design a bearing tooling, a bearing installation assembly and a bearing installation method that can ensure that the bearing pressure plate is locked from the outside, facilitate installation, and improve installation efficiency. Summary of the invention

[0005] The purpose of the present invention is to overcome the deficiencies of the prior art and to provide a bearing tooling, a bearing mounting assembly and a bearing mounting method which ensures locking of a bearing pressure plate from the outside, facilitates installation and improves installation efficiency.

[0006] The technical solution of the present invention provides a bearing fixture, comprising a plurality of bearing pressure plates, each of which is provided with a first bolt hole, and the bearing fixture further comprises a pressure plate positioning seat;

[0007] The pressure plate positioning seat is provided with a plurality of pressure plate positioning grooves distributed at intervals, and 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 an open position;

[0008] The bearing pressure plate is also provided with a positioning piece, and when the bearing pressure plate is connected to a bearing mounting seat for mounting a bearing, the positioning piece is used to position with the bearing mounting seat.

[0009] Furthermore, a plurality of positioning bosses are provided on the pressure plate positioning seat, and the positioning bosses 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 tooling also includes a clamping plate, which is arranged in the middle of the pressure plate positioning seat and is rotatably connected to the pressure plate positioning seat. The pressure plate extends a pressure strip toward the pressure plate positioning groove, and the pressure strip is used to press the bearing pressure plate in the pressure plate positioning groove.

[0011] The present invention also provides a bearing mounting assembly, including a bearing mounting seat and the bearing tooling described in any one of the above items.

[0012] Furthermore, the bearing mounting seat includes a raised mounting ring, the interior of the mounting ring is used to mount the bearing, and the mounting ring is provided with a plurality of second bolt holes distributed at intervals, and the second bolt holes are aligned with the first bolt holes and connected by bolts.

[0013] Furthermore, a plurality of limiting bosses are provided on the outer edge of the mounting ring, and the limiting bosses are used to cooperate with the positioning member.

[0014] Furthermore, a limiting surface is provided on the outer edge of the mounting ring. When the positioning member is separated from the limiting boss, the bearing pressure plate rotates to contact the limiting surface, and the bearing pressure plate 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 installation method using any one of the bearing installation assemblies described above, characterized in that it comprises the following steps:

[0049] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings.

Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the present invention, and should not be regarded as the whole of the present invention or as a limitation or restriction to the technical solution of the invention.

[0051] The directional terms such as up, down, left, right, front, back, front, back, top, bottom, etc. mentioned or may be mentioned in this specification are defined relative to the structures shown in the drawings. They are relative concepts and may change accordingly according to different positions and different usage conditions. Therefore, these or other directional terms should not be interpreted as restrictive terms.

[0052] Embodiment 1:

[0053] like Figure 1-Figure 2 As shown, the bearing fixture includes a plurality of 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 a plurality of pressure plate positioning grooves 21 distributed at intervals. When each bearing pressure plate 1 is embedded in one of the pressure plate positioning grooves 21, the plurality of bearing pressure plates 1 are in an open position.

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

[0056] Specifically, Figure 1 As shown, the housing of the drive assembly includes a main housing 20 and a separation housing 30. A bearing mounting seat 4 is provided on the inner side of the separation 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 limits the axial displacement of the bearing 10 to prevent the bearing 10 from escaping from 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 half-moon-shaped, and are provided with a first bolt hole 11 and a positioning member 12. The first bolt hole 11 is a through hole for installing the bolt 5, and the positioning member 12 is cylindrical and protrudes from the body of the bearing pressure plate 1. Preferably, the positioning member 12 can be a positioning pin or other positioning structure.

[0058] The pressure plate positioning seat 2 is disc-shaped, and three pressure plate positioning grooves 21 are provided on the pressure plate positioning seat 2. The shape of the pressure plate positioning groove 21 corresponds to the partial outer contour of the bearing pressure plate 1, so that the bearing pressure plate 1 can be just embedded in the pressure plate positioning groove 21, and the three bearing pressure plates 1 are in the open position after being installed in the pressure plate positioning seat 2. Here, the "open position" refers to the position of the bearing pressure plate 1, which will not interfere with the bearing 10 when matched with the bearing 10, so that the bearing 10 is easy to be installed in the bearing mounting seat 4.

[0059] The positioning member 12 is used to play a positioning role when it contacts the bearing mounting seat 4, so that the bearing pressure plate 1 and the bearing mounting seat 4 can be tightened and maintained in the open position by the bolt 5. In this way, when the pressure plate positioning seat 2 is separated from the bearing pressure plate 1, the three bearing pressure plates 1 can still be maintained in the open position, which is convenient for the bearing 10 to be installed in the bearing mounting seat 4.

[0060] like Figure 4 As shown, the pressure plate positioning seat 2 plays a role in preliminarily 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 means of bolts 5, the pressure plate positioning seat 2 is separated from the bearing pressure plate 1.

[0062] like Figure 7 As shown, the positioning member 12 is pressed against the limiting boss 43 on the bearing mounting seat 4, and at this time, the bolt 5 is tightened to fasten the bearing pressure plate 1 and the bearing mounting seat 4, thereby keeping the bearing pressure plate 1 in the open state.

[0063] like Fig. 9 As shown, the bearing 10 is installed in the bearing mounting seat 4 along the axial direction, and the bearing pressure plate 1 does not interfere with the bearing 10 at this time.

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

[0065] like Fig.12 As shown, tighten the bolt 5 again, and the bolt 5 drives the bearing pressure plate 1 to rotate together during the rotation, so that the bearing pressure plate 1 rotates around the central axis of the bolt 5 along the Fig.12 The bearing pressure plate 1 is rotated clockwise to be located on the inner side of the bearing 10.

[0066] like Fig.14 As shown, continue to tighten the bolts 5 until the bearing pressure plate 1 contacts the bearing 10 and restricts the bearing 10 in the 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, thereby ensuring the precise positioning of the bearing pressure plate 1 and the bearing mounting seat 4, facilitating installation and improving installation efficiency.

[0068] Furthermore, if Figure 2 As shown, the pressure plate positioning seat 2 is further provided with a plurality of positioning bosses 22 , which 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, Figure 2 As shown, the positioning boss 22 protrudes from the body of the pressure plate positioning seat 2 . There are three positioning bosses 22 , and they are located between adjacent pressure plate positioning grooves 21 . The positioning bosses 22 are arc-shaped and are located at the outer edge of the pressure plate positioning seat 2 .

[0070] like Figure 4 As shown, when the pressure plate locating seat 2 and the bearing pressure plate 1 are installed on the bearing mounting seat 4, the locating boss 22 contacts the angular locating 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 contacts the angular positioning surface 45, the three positioning bosses 22 surround the periphery of the bearing mounting seat 4, and the first bolt hole 11 on the bearing pressure plate 1 is just aligned with the second bolt hole 42 on the bearing mounting seat 4, and 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 with the bearing mounting seat 4.

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

[0073] Furthermore, if Figure 2-Figure 3 As shown, the bearing fixture further includes a clamping plate 3, which is disposed in the middle of the clamping plate positioning seat 2 and is rotatably connected to the clamping plate positioning seat 2, and a pressure strip 31 is extended from the clamping plate 3 toward the clamping plate positioning groove 21;

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

[0075] Specifically, Figure 2 As shown, the middle part of the clamping plate 3 is disc-shaped, and the clamping plate 3 is coaxially rotatably connected with the clamping plate positioning seat 2. The clamping plate 3 extends three pressure strips 31 in radial directions. 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, when the bearing pressure plate 1 is embedded in the pressure plate positioning groove 21, the clamping 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 direction and the circumferential direction to prevent the bearing pressure plate 1 from separating from the pressure plate positioning seat 2.

[0077] Preferably, if Figure 3 As shown, the edge of the first bolt hole 11 is provided with a convex ring 13 protruding from the bearing pressure plate 1. When the clamping plate 3 rotates, the pressure strip 31 contacts the convex ring 13, and the convex ring 13 acts as a limit to the pressure strip 31. At this time, the pressure strip 31 just rotates to the position to clamp the bearing pressure plate 1.

[0078] like Figure 7 As shown, the convex ring 13 can cooperate with the second bolt hole 42 on the bearing mounting seat 4 to play the function of guiding and rotation centering.

[0079] The bearing fixture in this embodiment can pre-position the bearing pressure plate 1, which not only ensures the positioning of the bearing pressure plate 1 when connected to the bearing mounting seat 4, but also ensures that the bearing pressure plate 1 is kept 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 achieving the limit of the bearing 10. The bearing pressure plate 1 and the bearing mounting seat 4 in this embodiment can be accurately positioned, making the installation more convenient and improving the installation efficiency.

[0080] Embodiment 2:

[0081] like Figure 5 As shown, the bearing mounting assembly includes a bearing mounting seat 4 and also includes any of the bearing tooling described above.

[0082] Specifically, the bearing mounting seat 4 includes a raised mounting ring 41 , the interior of the mounting ring 41 is used to mount the bearing 10 , and a plurality of second bolt holes 42 distributed at intervals are provided on the mounting ring 41 , and the second bolt holes 42 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 mounted inside the mounting ring 41. The mounting ring 41 is provided with three second bolt holes 42 at intervals, and the positions of the second bolt holes 42 protrude outward from the center of the circle to form a convex circular surface 46.

[0084] Furthermore, if Figure 5 As shown, a plurality of limiting bosses 43 are provided on the outer edge of the mounting ring 41 , and the limiting bosses 43 are used to cooperate with the positioning member 12 .

[0085] Specifically, Figure 5 As shown, the limiting boss 43 is arranged at a position close to the second bolt hole 42 and located on one side of the convex circular surface 46 , and 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 connected to the bearing mounting seat 4 in the open position, the positioning member 12 just contacts 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, and b = 0. The distance between the bearing pressure plate 1 and the top surface of the mounting ring 41 is a, and a>2mm.

[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 and 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, if Figure 5 and Fig.13 As shown, a limiting surface 44 is also provided on the outer edge of the mounting ring 41. When the positioning member 12 is separated 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. In the stop position, the bearing pressure plate 1 is used to stop the bearing 10.

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

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

[0091] In this embodiment, the bearing mounting seat 4 is arranged to achieve the coordination with the bearing pressure plate 1 in positioning and limiting, thereby achieving the installation positioning of the bearing pressure plate 1, the positioning of the open position and the limiting function of the stop position.

[0092] Embodiment three:

[0093] A bearing installation method of a bearing installation assembly comprises 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 on the bearing mounting seat 4, as shown in FIG. Figure 7 As shown, the positioning member 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 to keep the bearing pressure plate 1 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 Fig. 9 As shown, the bearing 10 is installed in the bearing mounting seat 4, as shown in FIG. Fig.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, and at this time 0mm<c≤1mm.

[0098] like Fig.11 As shown, the bolt 5 is loosened, and the positioning member 12 is separated from the bearing mounting seat 4, at which time 0mm<b<4mm;

[0099] like Fig.12 As shown, tighten the bolt 5 again, and the bolt 5 drives the bearing pressure plate 1 to rotate to the stop position;

[0100] like Fig.14 As shown, tighten the bolt 5, the bearing pressure plate 1 stops the bearing 10, at this time ac = 0, the bearing pressure plate 1 and the bearing 10 are pressed tightly, as shown in FIG. Fig.13 As shown, at this time, the positioning member 12 contacts the limiting surface 44, limiting the further rotation of the bearing pressure plate 1.

[0101] The present invention arranges the bearing pressure plate in the open position through the pressure plate positioning seat. After the bearing pressure plate is connected to the bearing mounting seat, the bearing pressure plate is kept in the open position by tightening the bearing pressure plate and the bearing mounting seat; then the bolts are loosened to separate the positioning piece from the bearing mounting seat; when the bolts are tightened, since the positioning piece is separated from the bearing mounting seat, the bolts can drive the bearing pressure plate to rotate, so that the bearing pressure plate rotates to the stop position, playing the role of a bearing stop, and finally the bolts are locked. The present invention can position the bearing pressure plate in the open position before installation, and after installation, the bearing pressure plate can be switched to the stop position by adjusting the bolts, ensuring that the bearing pressure plate is accurately positioned with the housing, facilitating installation, and improving installation efficiency.

[0102] The above description is only the principle and preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this field, several other modifications can be made based on the principle of the present invention, which should also be considered as the protection scope of the present invention.
