[0002] A servo motor end cap is a crucial component, typically located at the front or rear end of the motor. It supports the rotor assembly, seals the internal space, and maintains air and axial clearance. The servo motor end cap bearing chamber is the portion inside the end cap where the bearings are mounted. This structure typically supports the motor shaft, ensuring rotational accuracy and stability.

[0003] Chinese patent publication number CN220325382U discloses an end cover for a servo motor with high processing efficiency, comprising a motor end cover plate, a plurality of support bars and a support ring. The back of the motor end cover plate is provided with a flange, and the surface of the motor end cover plate is provided with a plurality of connection holes, the apertures of the plurality of connection holes are equal, and a bearing chamber and a support ring are welded to the front of the motor end cover plate, respectively, and the bearing chamber is coaxial with the support ring; the end cover welds the bearing chamber to the motor end cover plate, and the bearing can be placed through the bearing chamber, and the first clamping blocks of the plurality of support bars are respectively engaged with the plurality of first clamping grooves of the bearing chamber, so that the plurality of support bars can be quickly limited.

[0004] However, the above technical solution has the following shortcomings: the end cover structure directly welds the bearing chamber to the motor end cover plate. Although the bearing can be directly placed, it is not conducive to subsequent maintenance. In addition, the long-term use of the bearing will cause wear of the bearing chamber. At this time, the motor end cover needs to be processed and bearings of different sizes need to be replaced. The operation is relatively cumbersome and not conducive to use. Utility Model Content

[0005] The purpose of this utility model is to address the problems existing in the background technology and propose a servo motor end cover bearing chamber structure, which not only improves the impact resistance and deformation resistance of the motor end cover, but also facilitates the inspection and replacement of parts in the bearing chamber.

[0006] The technical solution of the utility model is a servo motor end cover bearing chamber structure, including an end cover and a reinforcement mechanism; a fixing tube and a cover plate are provided on the end cover; the reinforcement mechanism includes six support plates distributed in an annular array on the end cover, a support ring embedded with the support plate, and a sealing plate provided on the support ring, the support ring and the fixing tube are both provided with six card slots distributed in an annular array for embedding the two ends of the support plate, and the end cover is provided with a positioning groove for embedding the side edge of the support plate.

[0007] Preferably, a circular groove is provided on the end cover, and the cover plate is located inside the circular groove and fits with the fixing tube.

[0008] Preferably, the cover plate is provided with an axial hole and a plurality of first countersunk holes distributed in a circular array, the axial center line of the axial hole coincides with the fixing tube, a first fixing bolt passes through the interior of the first countersunk hole, and the first fixing bolt is threadedly connected to the fixing tube.

[0009] Preferably, a sleeve is provided inside the fixing tube, three fixing blocks are provided on the sleeve, and a limiting groove for the fixing blocks to be embedded in is provided on the fixing tube.

[0010] Preferably, three second countersunk holes are provided on the fixing tube, and second fixing bolts threadedly connected to the sleeve are provided inside the second countersunk holes.

[0011] Preferably, the sealing plate and the end cover are both provided with eight first mounting holes distributed in a ring array, and the sealing plate and the support ring are integrated.

[0012] Preferably, the end cover is provided with four second mounting holes distributed in a rectangular array.

[0013] Compared with the prior art, the present invention has the following beneficial technical effects:

[0014] 1. The utility model can enhance the impact resistance and deformation resistance of the end cover through the reinforcement mechanism, thereby improving the service life. In addition, the support plate and support ring can be installed or disassembled, which is convenient for the inspection and replacement of the parts of the bearing chamber.

[0015] 2. The utility model avoids the direct installation of the bearing on the inner wall of the fixed tube by providing a sleeve. The long-term operation of the motor causes the inner wall of the fixed tube to be easily deformed and severely worn. In addition, the sleeve can be quickly replaced by cooperating with the fixing block, the second countersunk hole and the second fixing bolt, which has good practicality.

DETAILED DESCRIPTION

[0022] Example 1

[0023] like Figure 1-Figure 5 As shown, a servo motor end cover bearing chamber structure proposed in this embodiment includes an end cover 1 and a reinforcement mechanism; a fixing tube 2 and a cover plate 4 are provided on the end cover 1.

[0024] like Figure 1 、 Figure 2 、 Figure 4 and Figure 5 As shown, the reinforcement mechanism includes six support plates 6 distributed in a circular array on the end cover 1, a support ring 7 embedded in the support plate 6, and a sealing plate 19 arranged on the support ring 7. The support ring 7 and the fixed tube 2 are both provided with six card slots 8 distributed in a circular array for the support plates 6 to be embedded at both ends, and the end cover 1 is provided with a positioning groove 9 for the side of the support plate 6 to be embedded.

[0025] A circular groove 10 is provided on the end cover 1, the cover plate 4 is located inside the circular groove 10 and fits with the fixed tube 2, and the cover plate 4 is provided with an axial hole 5 and a plurality of first countersunk holes 11 distributed in a circular array. The axial center line of the axial hole 5 coincides with the fixed tube 2, and a first fixing bolt 12 passes through the inside of the first countersunk hole 11, and the first fixing bolt 12 is threadedly connected to the fixed tube 2.

[0026] In this embodiment, the support plate 6 and support ring 7 are provided to enhance the impact resistance and deformation resistance of the end cover 1, thereby improving its service life. In addition, the support plate 6 and support ring 7 can be installed or disassembled, which is convenient for inspecting and replacing the parts of the bearing chamber. When assembling, the support plate 6 is first embedded in the positioning groove 9, and then the slots 8 of the fixing tube 2 and the support ring 7 are engaged with the positioning groove 9, and then the cover plate 4 is placed in the annular groove 10 and made to fit with the bottom of the fixing tube 2. Finally, the first fixing bolt 12 is screwed into the first countersunk hole 11, and the sealing plate 19 is fixed to the end cover 1 to complete the fixed installation of the reinforcement component and the fixing tube 2, which has good practicality.

[0027] Example 2

[0028] like Figure 2 and Figure 3As shown, a servo motor end cover bearing chamber structure is proposed in this embodiment. Compared with the first embodiment, in this embodiment, a sleeve 3 is provided inside the fixed tube 2, three fixing blocks 13 are provided on the sleeve 3, and a limiting groove 15 for the fixing blocks 13 to be embedded is provided on the fixed tube 2. Three second countersunk holes 16 are provided on the fixed tube 2, and a second fixing bolt 14 threadedly connected to the sleeve 3 is provided inside the second countersunk hole 16.

[0029] In this embodiment, the sleeve 3 and cover plate 4 form a bearing chamber, avoiding the need for the bearing to be directly mounted on the inner wall of the fixed tube 2. This would easily cause deformation and severe wear of the inner wall of the fixed tube 2 due to long-term operation of the motor. The sleeve 3 ensures that when the bearing chamber needs to be replaced, it only needs to be replaced by replacing the sleeve 3. When the sleeve 3 needs to be replaced, the second fixing bolt 14 is first unscrewed from the second countersunk hole 16, and then the old sleeve 3 is removed from the limiting groove 15 through the fixing block 13. The new sleeve 3 is then replaced and secured. This simple and convenient operation ensures that the performance of the motor end cover 1 is maintained.
