Technical Field

[0001] This utility model relates to a motor sealing end cover, specifically a motor sealing end cover, and belongs to the technical field of motor components. Background Technology

[0002] The motor end cover is an important component of the motor. It not only provides support and positioning for internal components such as bearings, but also protects the internal structure of the motor and prevents impurities such as dust and moisture from entering. It is of great significance for ensuring the normal operation of the motor and extending its service life. Dust covers are usually installed on the motor end cover to shield and protect the bearings from corrosion by external impurities. When the bearings need to be lubricated, the dust cover needs to be removed.

[0003] However, the dust covers on traditional motor end covers are usually installed on the motor end cover with multiple bolts. During the disassembly and assembly process, tools such as wrenches are needed to tighten each bolt one by one, which is cumbersome and time-consuming, causing many inconveniences to the lubrication of the bearings and thus reducing the efficiency of bearing lubrication. Utility Model Content

[0004] The purpose of this invention is to provide a motor sealing end cover to solve the above problems, which enables quick disassembly and assembly of the dust cover, thereby facilitating rapid lubrication of the bearing and effectively improving the efficiency of bearing lubrication.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a motor sealing end cover, comprising a cover body, one end of the cover body abutting against a dust cover, four positioning protrusions integrally formed on one side of the dust cover, four slots corresponding one-to-one with the positioning protrusions on the dust cover, the positioning protrusions engaging with adjacent slots, a plurality of second slots on the dust cover, a first slot on the positioning protrusions, the same first elastic retaining ring engaging inside the plurality of second slots and the plurality of first slots, and a sealing structure on the cover body.

[0006] Preferably, the four positioning protrusions are arranged in a circumferential array about the center of the dust cover, and the cross-section of one end of the positioning protrusion is trapezoidal.

[0007] Preferably, the center of the cover and the center of the dust cover are on the same straight line, and the four latches are arranged in a circular array about the middle of the cover.

[0008] Preferably, the sealing structure includes a sealing ring and a retaining ring. The sealing ring is engaged with the cover body, and one side of the sealing ring abuts against the retaining ring. Four lugs are integrally formed on the outer side of the retaining ring. The cover body is provided with multiple third slots, and the same second elastic retaining ring is engaged inside the multiple third slots. One side of the second elastic retaining ring abuts against the four lugs.

[0009] Preferably, the cover body has a placement groove inside, the sealing ring is placed inside the placement groove, the inner diameter of the retaining ring is smaller than the inner diameter of the sealing ring, and the inner diameter of the retaining ring is larger than the outer diameter of the sealing ring.

[0010] Preferably, the cover has multiple openings, the lugs engage with adjacent openings, and the four lugs are arranged in a circumferential array about the center of the retaining ring.

[0011] Preferably, a plurality of heat sinks are fixedly connected to one side of the cover, and the plurality of heat sinks are arranged in a circular array about the middle of the cover.

[0012] Preferably, a plurality of reinforcing ribs are fixedly connected to the other side of the cover, and the plurality of reinforcing ribs are distributed in a circumferential array about the middle of the cover.

[0013] Preferably, a plurality of mounting blocks are fixedly connected to the outer side of the cover, and the plurality of mounting blocks are arranged in a circumferential array about the middle of the cover, and the mounting blocks are provided with mounting holes.

[0014] The beneficial effects of this utility model are as follows: When the dust cover needs to be removed for bearing lubrication, the first elastic retaining ring can be opened using retaining ring pliers. After the first elastic retaining ring is opened, its inner diameter will increase. Then, the first elastic retaining ring can be moved to disengage from the interior of multiple first and multiple second retaining slots. Then, the dust cover can be moved to disengage the positioning protrusion from the interior of the slot, thus achieving quick disassembly of the dust cover. When the dust cover needs to be installed, the positioning protrusion can be inserted into the corresponding slot to position the dust cover, preventing it from rotating and improving the stability of the dust cover after installation. When one side of the dust cover abuts against the cover body, the end of the first slot is aligned with the end of the second slot. Then, the retaining ring pliers can be used to make the first elastic retaining ring engage with the multiple first and multiple second retaining slots again. At this time, the dust cover cannot be moved, thus achieving quick installation of the dust cover. Therefore, when the bearing needs to be lubricated, the dust cover can be quickly disassembled and installed, thereby shortening the bearing lubrication time and improving the efficiency of bearing lubrication.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-7 As shown, a motor sealing end cover includes a cover body 1, one end of which abuts against a dust cover 2. The center of the cover body 1 and the center of the dust cover 2 are on the same straight line. Four positioning protrusions 3 are integrally formed on one side of the dust cover 2. The dust cover 2 has four slots 6 that correspond one-to-one with the positioning protrusions 3. The four slots 6 are arranged in a circumferential array about the middle of the cover body 1. The positioning protrusions 3 engage with the adjacent slots 6. The dust cover 2 has multiple second slots 5. The positioning protrusions 3 have first slots 4. The multiple second slots 5 and the multiple first slots 4 are engaged with the same first elastic retaining ring 7. The cover body 1 has a sealing structure 8.

[0025] As a technical optimization of this utility model, the four positioning protrusions 3 are arranged in a circular array about the middle of the dust cover 2. Therefore, the dust cover 2 can be positioned by engaging with the positioning protrusions 3 and the corresponding latches 6. The cross-section of one end of the positioning protrusion 3 is trapezoidal, so it can play a role in guiding the movement when the positioning protrusion 3 and the latches 6 are engaged.

[0026] As a technical optimization of this utility model, the sealing structure 8 includes a sealing ring 801 and a retaining ring 802. The sealing ring 801 is engaged on the cover 1. The sealing performance between the dust cover 2 and the motor shaft can be improved by the contact between the sealing ring 801 and the motor shaft. One side of the sealing ring 801 is engaged with the retaining ring 802. Four lugs 803 are integrally formed on the outer side of the retaining ring 802. The retaining ring 802 can be fixed by the contact between the second elastic retaining ring 804 and the multiple lugs 803, thereby fixing the sealing ring 801 by the retaining ring 802. The cover 1 is provided with multiple third slots 805. The same second elastic retaining ring 804 is engaged inside the multiple third slots 805. One side of the second elastic retaining ring 804 is engaged with the four lugs 803.

[0027] As a technical optimization of this utility model, the cover 1 is provided with a placement groove 807 inside. Since the outer diameter of the placement groove 807 is equal to the outer diameter of the sealing ring 801, the sealing ring 801 can be positioned after it is placed inside the placement groove 807. The sealing ring 801 is placed inside the placement groove 807. The inner diameter of the retaining ring 802 is smaller than the inner diameter of the sealing ring 801, and the inner diameter of the retaining ring 802 is larger than the outer diameter of the sealing ring 801. Therefore, the sealing ring 801 can be fixed by the retaining ring 802.

[0028] As a technical optimization of this utility model, the cover 1 is provided with multiple openings 806, the lugs 803 engage with the adjacent openings 806, and the four lugs 803 are arranged in a circumferential array about the middle of the retaining ring 802, thus limiting the retaining ring 802.

[0029] As a technical optimization of this utility model, a plurality of heat sinks 9 are fixedly connected to one side of the cover 1. The plurality of heat sinks 9 are arranged in a circumferential array about the middle of the cover 1. Therefore, the contact area between the cover 1 and the air can be increased by the plurality of heat sinks 9, thereby facilitating the heat dissipation of the motor.

[0030] As a technical optimization of this utility model, a plurality of reinforcing ribs 10 are fixedly connected to the other side of the cover 1. The plurality of reinforcing ribs 10 are arranged in a circular array about the middle of the cover 1. By setting a plurality of reinforcing ribs 10, the overall structural strength of the cover 1 can be improved.

[0031] As a technical optimization of this utility model, a plurality of mounting blocks 11 are fixedly connected to the outer side of the cover 1. The plurality of mounting blocks 11 are arranged in a circumferential array about the middle of the cover 1. The mounting blocks 11 are provided with mounting holes 12, so that the cover 1 can be installed on the motor housing.

[0032] In use, this utility model allows the mounting block 11 to be installed on the motor housing via multiple mounting holes 12 and nuts and bolts, thus achieving the installation of the cover 1. When the dust cover 2 needs to be removed for bearing lubrication, the first elastic retaining ring 7 can be opened using retaining ring pliers. After the first elastic retaining ring 7 is opened, its inner diameter will increase. Then, the first elastic retaining ring 7 can be moved to disengage from the multiple first slots 4 and multiple second slots 5. Then, the dust cover 2 can be moved to disengage the positioning protrusion 3 from the slot 6, thus achieving quick disassembly of the dust cover 2. When the dust cover 2 needs to be installed, the positioning protrusion 3 can be inserted into the corresponding slot 6 to position the dust cover 2, preventing the dust cover 2 from rotating and improving the stability of the dust cover 2 after installation. When one side of the dust cover 2 abuts against the cover 1, the end of the first slot 4 is aligned with the end of the second slot 5. Then, the first elastic retaining ring can be moved again using retaining ring pliers. 7 engages simultaneously with multiple first slots 4 and multiple second slots 5, at which point the dust cover 2 cannot move, thus achieving quick installation of the dust cover 2. Therefore, when the bearing needs to be lubricated, the dust cover 2 can be quickly disassembled and assembled, thereby shortening the bearing lubrication time and improving the bearing lubrication efficiency. The contact between the sealing ring 801 and the motor shaft can improve the sealing between the dust cover 2 and the motor shaft, thereby preventing dust from entering the bearing from the gap between the dust cover 2 and the motor shaft and causing contamination to the bearing. When the sealing ring 801 is damaged and needs to be replaced, the dust cover 2 can be removed first, and then the second elastic retaining ring 804 can be removed from the cover body 1 using retaining ring pliers. Then, the retaining ring 802 can be removed from the cover body 1, and finally, the damaged sealing ring 801 can be taken out from the inside of the placement groove 807, thereby achieving quick disassembly of the sealing ring 801, facilitating the replacement of the damaged sealing ring 801, and thus improving the efficiency of the inspection and maintenance of the sealing ring 801.
