Description

Technical Field

[0001] The utility model relates to the technical field of motors, and in particular to a novel motor driving structure. Background Art

[0002] With the advancement of industrialization, motors are increasingly used in various fields (such as manufacturing, transportation, and home appliances), and motor drive technology is also constantly evolving and innovating.

[0003] However, existing motor drive structures typically rely on an internal bearing system to support the rotor and ensure smooth rotation. Bearings reduce friction and support the rotor's rotational motion, ensuring efficient motor operation. The rotor is supported on both sides by bearings, while a gap exists between the center and the stator. This can cause uneven forces on the rotor during rotation, especially at high speeds. This design can cause rotor eccentricity (imbalance), which can lead to irregular rotor vibration during rotation. This not only affects motor performance but can also accelerate bearing wear. Utility Model Content

Especially when running at high speed, this design may cause the rotor to be eccentric (unbalanced).

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions: a new motor drive structure, including a motor body, a first bearing is fixedly embedded in the left side of the inner wall of the motor body, the inner ring of the first bearing is provided with a rotating shaft, the outer surface of the rotating shaft is provided with a rotor, the outer surface of the rotor is provided with multiple sliding grooves, the inner surfaces of the multiple sliding grooves are slidably connected with sliders on both sides, the outer sides of the multiple sliders are fixedly installed with telescopic rods, the outer sides of the multiple sliders are fixedly installed with return springs, the inner surfaces of the multiple return springs are movably sleeved on the outer surface of the telescopic rod, the multiple return springs and the multiple telescopic rods are divided into multiple groups of two, the other ends of the multiple groups of return springs and the multiple groups of telescopic rods are fixedly installed inside the rotor, and the outer sides of the multiple sliders are fixedly installed with a first hinge.

[0010] As a preferred embodiment, two balls are movably connected inside each of the plurality of connecting blocks, and a stator is provided on the inner wall of the motor body.

[0011] The technical effect of adopting the above further solution is that the balls can be driven to move by the connecting block.

[0012] As a preferred embodiment, the outer surfaces of the plurality of balls are movably connected to the inner surface of the stator, and a second bearing is fixedly installed on the right side inside the motor body.

[0013] The technical effect of adopting the above further solution is that the balls can be made to rotate in contact with the inner wall of the stator.

[0014] As a preferred embodiment, the inner ring of the second bearing is movably sleeved on the outer surface of the rotating shaft, and a placement groove is opened inside the motor body.

[0019] The technical effect of adopting the above further solution is that the coolant inside the spiral copper tube can be drawn out through the water outlet pipe.

[0020] Compared with the prior art, the advantages and positive effects of the present invention are:

[0021] 1. When in use, the present invention, through the arrangement of the ball and cross rod structure, not only can the ball always fit into the inside of the stator, thereby providing additional supporting force for the rotating shaft, this supporting force can effectively reduce the shaking and deviation of the rotating shaft during rotation, improve the stability of the rotating shaft, and enable it to drive the rotor to rotate more smoothly, thereby ensuring the normal operation and working efficiency of the motor.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Example 1, please refer to Figures 1 to 4 The utility model provides a technical solution: a new motor drive structure, including a motor body 1, a first bearing 101 is fixedly embedded on the left side of the inner wall of the motor body 1, a rotating shaft 102 is provided on the inner ring of the first bearing 101, a rotor 103 is provided on the outer surface of the rotating shaft 102, a plurality of slide grooves 105 are opened on the outer surface of the rotor 103, and sliders 106 are slidably connected on both sides of the inner surfaces of the plurality of slide grooves 105, and telescopic rods 107 are fixedly installed on the outer sides of the plurality of sliders 106, and return springs 108 are fixedly installed on the outer sides of the plurality of sliders 106, and the inner surfaces of the plurality of return springs 108 are movably sleeved on the outer surface of the telescopic rod 107, and the plurality of return springs 108 and the plurality of telescopic rods 107 are divided into a plurality of groups in pairs, and the plurality of return springs 108 are divided into a plurality of groups in pairs, and the plurality of return springs 108 are fixedly sleeved on the outer surface of the telescopic rod 107. The other ends of the spring 108 and the multiple groups of telescopic rods 107 are fixedly installed inside the rotor 103, and the outer sides of the multiple sliders 106 are fixedly installed with a first hinge 109. The multiple first hinges 109 are divided into multiple groups of two, and the interiors of the multiple groups of first hinges 109 are movably connected with cross vertical rods 110. The other ends of the multiple cross vertical rods 110 are movably connected to two second hinges 111. The outer sides of the multiple second hinges 111 are fixedly installed with connecting blocks 112, and the interiors of the multiple connecting blocks 112 are movably connected to two balls 113. The inner wall of the motor body 1 is provided with a stator 104, and the outer surfaces of the multiple balls 113 are movably connected to the inner surface of the stator 104. A second bearing 114 is fixedly installed on the right side of the interior of the motor body 1.

[0031] In this embodiment, the rotating shaft 102 can rotate inside the motor body 1 through the inner ring of the first bearing 101 and the second bearing 114, and the rotating shaft 102 drives the rotor 103 to rotate, so that when the rotor 103 rotates, it can drive the ball 113 to adhere to the inner surface of the stator 104 through the cross rod 110 and the connecting block 112 to rotate synchronously, and when the ball 113 rotates, it will squeeze the second hinge 111 through the connecting block 112, and then press the cross rod 110 down through the second hinge 111, so that the cross rod 110 flips over through its internal rotating shaft and expands outward. When the cross rod 110 expands, it pulls the slider 106 to slide outward on the inner surface of the slide groove 105 through the first hinge 109, and through the slider 106 The return spring 108 and the telescopic rod 107 are squeezed to shrink, so that the ball 113 can always fit the inside of the stator 104 to provide additional support for the rotating shaft 102. Moreover, through the arrangement of the ball 113 and the cross vertical rod 110 structure, not only can the ball 113 always fit the inside of the stator 104, thereby providing additional support for the rotating shaft 102, this support force can effectively reduce the shaking and deviation of the rotating shaft 102 during rotation, improve the stability of the rotating shaft 102, and enable it to drive the rotor 103 to rotate more smoothly, thereby ensuring the normal operation and working efficiency of the motor. At the same time, this structure can avoid stress concentration on a few parts such as bearings, reduce the risk of wear and damage to these parts, and extend the service life of the entire drive structure.

[0032] Example 2, as Figures 1 to 4 As shown, the inner ring of the second bearing 114 is movably sleeved on the outer surface of the rotating shaft 102, and a placement groove 2 is opened inside the motor body 1. A spiral copper tube 201 is fixedly installed inside the placement groove 2, and a water inlet pipe 202 is fixedly installed at the front end of the spiral copper tube 201. The outer surface of the water inlet pipe 202 is fixedly embedded in the front side of the motor body 1. The other end of the spiral copper tube 201 is fixedly installed with a water outlet pipe 203, and the outer surface of the water outlet pipe 203 is fixedly embedded in the top side of the motor body 1.

[0033] In this embodiment, personnel can inject coolant into the inside of the spiral copper tube 201 in the placement tank 2 through the water inlet pipe 202. When the coolant enters the inside of the spiral copper tube 201, it will circulate from left to right inside the spiral copper tube 201, thereby cooling the motor body 1. At the same time, personnel can extract the coolant inside the spiral copper tube 201 through the water outlet pipe 203. The setting of the structure of the water inlet pipe 202 and the spiral copper tube 201 not only can cool the motor body 1, but also due to the setting of the spiral structure of the spiral copper tube 201, the contact area between the coolant and the tube wall can be increased. This structure helps to improve the heat exchange efficiency, so that the coolant can more effectively take away the heat generated by the motor body 1.

[0034] Working principle: When in use, the rotating shaft 102 can rotate inside the motor body 1 through the inner ring of the first bearing 101 and the second bearing 114, and drive the rotor 103 to rotate through the rotating shaft 102, so that when the rotor 103 rotates, it can drive the ball 113 to adhere to the inner surface of the stator 104 through the cross rod 110 and the connecting block 112 to rotate synchronously, and when the ball 113 rotates, it will squeeze the second hinge 111 through the connecting block 112, and then press the cross rod 110 down through the second hinge 111, so that the cross rod 110 flips over through its internal rotating shaft and expands outward. When the cross rod 110 expands, it will pull the slider 106 to slide outward on the inner surface of the slide groove 105 through the first hinge 109, and through the slider 1 06 squeezes the return spring 108 and the telescopic rod 107 to shrink, so that the ball 113 can always fit the inside of the stator 104 to provide additional support for the rotating shaft 102. The arrangement of the ball 113 and the cross rod 110 structure not only enables the ball 113 to always fit the inside of the stator 104, thereby providing additional support for the rotating shaft 102, but this support can effectively reduce the shaking and deviation of the rotating shaft 102 during rotation, improve the stability of the rotating shaft 102, and enable it to drive the rotor 103 to rotate more smoothly, thereby ensuring the normal operation and working efficiency of the motor. At the same time, this structure can avoid stress concentration on a few parts such as bearings, reduce the risk of wear and damage to these parts, and extend the service life of the entire drive structure. During use, personnel can inject coolant into the inside of the spiral copper tube 201 in the placement groove 2 through the water inlet pipe 202. When the coolant enters the inside of the spiral copper tube 201, it will circulate from left to right inside the spiral copper tube 201, thereby cooling the motor body 1. At the same time, personnel can extract the coolant inside the spiral copper tube 201 through the water outlet pipe 203. The setting of the structure of the water inlet pipe 202 and the spiral copper tube 201 not only can cool the motor body 1, but also due to the setting of the spiral structure of the spiral copper tube 201, the contact area between the coolant and the tube wall can be increased. This structure helps to improve the heat exchange efficiency, so that the coolant can more effectively take away the heat generated by the motor body 1.
