[0001] The utility model relates to the technical field of motor equipment, in particular to a motor connecting seat and a motor. Background Art

[0002] Generally, it is difficult to completely eliminate the vibration generated by high-speed motors, especially those with large rotor inertia. At the same time, high-speed motors usually use a reduction gearbox to reduce the output speed. When the motor is connected to the reduction gearbox, the vibration will be transmitted to the reduction gearbox. When the vibration of the motor cannot be reduced, the technicians will make a vibration isolation connection between the motor and the reduction gearbox.

[0003] The vibration isolation between the motor and the gearbox often adds rubber pads between the contact surface between the motor and the gearbox and between the screw and the gearbox, so that the motor and the gearbox are not in direct contact, and the gearbox and the fasteners are not in direct contact, avoiding vibration transmission caused by hard contact and reducing noise. When the screws are tightened, the hardness of the rubber at the connection will become harder due to the compression of the screws, thereby reducing the shock absorption effect. Utility Model Content

[0004] The main purpose of the utility model is to provide a motor connecting seat, aiming to prevent the rubber from reducing the shock absorption effect due to the locking of screws.

[0005] In order to achieve the above-mentioned purpose, the motor connection seat proposed in the utility model is used to connect the motor body and the reduction box, and the motor connection seat includes:

[0009] Optionally, the bottom wall of each of the undercut grooves is provided with three of the connecting holes, and the three connecting holes are arranged at intervals along the circumferential direction of the connecting piece; each of the buckle parts includes a stop block and three connecting ribs, and each of the connecting ribs passes through one of the connecting holes.

[0010] Optionally, the buffer component is made of silicone.

[0011] Optionally, the outer circumferential surface of each of the connecting members and the outer circumferential surface of each of the buffer members are both circular surfaces.

[0012] Optionally, each of the connecting members forms four undercut grooves, and the four undercut grooves are arranged on the connecting member at intervals along the circumferential direction of the connecting member, and the shape of each undercut groove is a fan.

[0013] Optionally, each of the stop blocks is fan-shaped and the outer peripheral wall of each of the stop blocks can abut against the peripheral wall of one of the undercut grooves.

[0014] The utility model also provides a motor, the motor comprising:

[0015] A motor body, an output shaft and any one of the above-mentioned motor connection seats, wherein the output shaft is arranged on the motor body; the motor connection seat is formed with a through hole penetrating the two connecting members and the buffer member and a plurality of first threaded holes; the motor connection seat is threadedly connected to the body through each of the first threaded holes; and the output shaft is passed through the through hole.

[0029] Please refer to Figure 1 , Figure 2 as well as Figure 3 In order to solve the problem that the rubber pad hardens due to screw locking and reduces the shock absorption effect, the utility model proposes a motor connection seat 1000, including:

[0030] The buffer member 2 and two connecting members 1, each connecting member 1 is formed with at least one undercut groove 11; one connecting member 1 is used to connect the motor body 5, and the other connecting member 1 is used to connect the reduction box a; the buffer member 2 includes a buffer layer 21 and a plurality of snap parts 22 arranged on both sides of the buffer layer 21, and one undercut groove 11 of each connecting member 1 is snapped with one snap part 22, and the buffer layer 21 is located between the two connecting members 1. The buffer layer 21 is sandwiched between the two connecting members 1, and the snap parts 22 on both sides of the buffer layer 21 are snapped into the undercut groove 11 so that the buffer layer 21 will not fall off from between the two connecting members 1, and then the two connecting members 1 are respectively connected to the motor 2000 and the reduction box a, so that the buffer layer 21 can be limited between the motor 2000 and the reduction box a to achieve the buffering effect of the buffer layer 21.

[0031] In the technical solution of the present utility model, since the buffer layer 21 is sandwiched between the two connectors 1, the contact area between the connector 1 and the buffer layer 21 is increased, and thus the local pressure on the buffer layer 21 is reduced, thereby preventing the buffer layer 21 from hardening due to excessive pressure and reducing the shock absorption effect; at the same time, the buffer 2 and the connector 1 are connected by snapping instead of screwing, which can avoid the problems of weakening of the screw pre-tightening force and loosening of the buffer 2 and the connector 1 caused by aging of the buffer 2.

[0032] Each buckle portion 22 includes a stopper 221 and a connecting rib 222. In one embodiment, a connecting hole 12 is provided on the bottom wall of each undercut groove 11, and each connecting rib 222 passes through a connecting hole 12 to connect a stopper 221, and each stopper 221 is accommodated in an undercut groove 11; the stopper 221 and the bottom wall of the undercut groove 11 are stopped and limited. Of course, in another embodiment, the connecting rib 222 can be arranged at the outer periphery of the connector 1 and connect the buffer layer 21 and the stopper 221. Compared with the connecting rib 222 connecting the stopper 221 at the outer periphery of the connector 1, the stopper 221 can be stopped and limited by the bottom wall of the undercut groove 11 when the connecting rib 222 passes through the connecting hole 12. Therefore, the probability of the stopper 221 sliding out of the undercut groove 11 can be reduced to a certain extent, thereby making the structure of the motor connector 1000 more stable.

[0033] The bottom wall of each undercut groove 11 is provided with one or more connecting holes 12. In one embodiment, the bottom wall of each undercut groove 11 is provided with three connecting holes 12, and the three connecting holes 12 are arranged at intervals along the circumferential direction of the connector 1; each buckle portion 22 includes a stop block 221 and three connecting ribs 222, and each connecting rib 222 passes through a connecting hole 12. There will be gaps between the three connecting holes 12, and the gaps are the physical structure of the connector 1. Part of the stop block 221, two connecting ribs 222 and part of the buffer layer 21 together constitute a closed structure, and the physical structure between the connecting holes 12 is located in the closed structure; at the same time, the hole wall of the connecting hole 12 forms a closed structure, and the connecting rib 222 is located in this closed structure. Therefore, part of the structure of the connector 1 and part of the structure of the buffer 2 can be regarded as two mutually nested rings, so the connector 1 and the buffer 2 are extremely difficult to separate, thereby making the structure of the motor connector 1000 more stable.

[0034] It is understandable that the hardness of the material selected for the buffer is between 35° and 45° on the Shore A scale, and common materials in this hardness range include rubber, silicone and latex. In one embodiment, the material of the buffer is silicone. If the hardness of the buffer is too high, the buffering effect will be weakened, resulting in a reduced shock absorption effect; if the hardness is too low, the snap-fitting effect between the snap part and the undercut groove will be poor and easy to fall off, making the overall structure of the motor connection seat unstable. Therefore, the material of the buffer is preferably silicone, which is not easy to fall off in the undercut groove while satisfying a good buffering effect. At the same time, in order to ensure the connection strength, the material of the connector is plastic or metal. In one embodiment, the material of the connector is plastic.

[0035] The outer circumferential surface of each connector 1 and the outer circumferential surface of each buffer 2 can be a square or a circular surface. In one embodiment, the outer circumferential surface of each connector 1 and the outer circumferential surface of each buffer 2 are both circular surfaces. Because the cross-section of the rotor of the motor 2000 is usually circular, the motor 2000 will also be mostly made into a cylindrical shape. The outer circumferential surface of the connector 1 and the outer circumferential surface of the buffer 2 are both circular surfaces, so that the motor connector 1000 formed by them is cylindrical and can be compatible with most motors 2000; at the same time, the distance from the center to the outer edge of the cylindrical motor connector 1000 is the same, so that the structure of the motor connector 1000 is more stable.

[0036] Each connector 1 may form one or more undercut grooves 11, and the shape of the undercut grooves 11 may be fan-shaped or square. In one embodiment, each connector 1 forms four undercut grooves 11, and the four undercut grooves 11 are arranged at intervals on the connector 1 along the circumferential direction of the connector 1, and the shape of each undercut groove 11 is fan-shaped. Since the outer circumferential surface of the connector 1 is a circular surface, and the four undercut grooves 11 are evenly arranged on the connector 1 along the circumferential direction of the connector 1, the fan-shaped undercut groove 11 can maximize the bottom wall area of ​​the undercut groove 11, that is, the contact area between the undercut groove 11 and the stop block 221 is maximized, so that the stopping effect of the undercut groove 11 is better; at the same time, the four undercut grooves 11 are evenly arranged on the connector 1 along the circumferential direction of the connector 1, so after the motor 2000 is started, the four buckle parts 22 and the buckle structure of the four undercut grooves 11 are subjected to the same force, that is, the buffer 2 is subjected to the same force in four directions, so that the overall structural stability of the motor connector 1000 can be maintained.

[0037] It is understandable that the shape of the stop block 221 can be sector-shaped or square. In one embodiment, the shape of each stop block 221 is sector-shaped and the outer peripheral wall of each stop block 221 can abut against the peripheral wall of an undercut groove 11. Such an arrangement maximizes the contact area between the stop block 221 and the bottom wall of the undercut groove 11, thereby achieving a better stopping effect of the undercut groove 11.

[0038] The utility model also proposes a motor 2000, which includes a motor connecting seat 1000. The specific structure of the motor connecting seat 1000 refers to the above-mentioned embodiment. Since the motor 2000 adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here.

[0039] It can be understood that the motor body 5 can be screwed to the motor connection seat 1000 through a bolt structure, or can be pinned to the motor connection seat 1000 through a pin. In one embodiment, the motor 2000 includes a motor body 5, an output shaft 6 and a motor connection seat 1000, and the output shaft 6 is arranged on the motor body 5; the motor connection seat 1000 is formed with a through hole 23 and a plurality of first threaded holes 3 that penetrate the two connecting members 1 and the buffer member 2; the motor connection seat 1000 is screwed to the main body through each first threaded hole 3; the output shaft 6 is penetrated in the through hole 23. The screw connection method makes the connection between the motor body 5 and the motor connection seat 1000 more stable. Similarly, the motor connection seat 1000 is formed with a second threaded hole 4 that penetrates the connecting member 1 of the two connecting members 1 away from the motor body 5, and the reduction box a can also be screwed to the motor connection seat 1000 through a bolt structure.

[0040] In one embodiment, the motor 2000 further includes a coupling 7, which is inserted into the through hole 23 and connected to the output shaft 6, and the coupling 7 is used to connect the input shaft a1 of the reduction box a. The output shaft 6 of the motor 2000 and the input shaft a1 of the reduction box a are connected by the coupling 7, so that the output power of the motor 2000 can be transmitted to the reduction box a.

[0041] The coupling 7 may be a rigid coupling 7 or a flexible coupling 7. In one embodiment, the coupling 7 is a flexible coupling 7. The use of the flexible coupling 7 can not only compensate for the relative displacement between the output shaft 6 of the motor 2000 and the input shaft a1 of the reduction box a, but also has a buffering and vibration isolation effect, so that the shock absorption effect between the motor 2000 and the reduction box a is better.

[0042] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
