In a specific embodiment, the gap adjusting device 10 provided by the present invention includes an adjusting rod 101, a first moving slider 102 and a second moving slider 103, wherein the inner sides of the first moving slider 102 and the second moving slider 103 are both provided with an inclined surface, and the first moving slider 102 and the second moving slider 103 are matched through the inclined surfaces, and the adjusting rod 101 firstly passes through the first moving slider 102, then passes through the second moving slider 103, and is in threaded connection with the second moving slider 103.
In the present embodiment, the gap adjusting device 10 is used for adjusting the gap between different motor components, and the external dimension, such as the width or the thickness, of the gap adjusting device 10 is changed by screwing the adjusting rod 101, which is equivalent to the increase or decrease of the gasket in the prior art, so as to meet the requirement of gap adjustment. It should be noted that the gap includes, but is not limited to, an axial gap, and may also be a radial gap, and the gap adjusting device 10 may be disposed in different directions along the axial direction or the radial direction, so as to obtain the gap adjusting effect in different directions.
Specifically, the outer sides of the first moving slider 102 and the second moving slider 103 are respectively connected to end faces of different motor parts in a contact manner, and when the different motor parts are fixedly connected, the first moving slider 102 and the second moving slider 103 are sandwiched between the two and fixed, and at this time, the first moving slider 102 and the second moving slider 103 are gaps between the two.
In use, taking the example of axial clearances between different motor components and adjusting the different motor components in the axial direction, the radial clearances should be similar.
In this embodiment, the adjusting rod 101 is equivalent to an adjusting bolt, the adjusting bolt is screwed in, and the second moving block 103 is axially displaced by an axial force of a screw screwed into the adjusting bolt, so as to press an inclined surface between the first moving block 102 and the second moving block 103, thereby generating a radial force perpendicular to the axial force on the first moving block 102. The first movable slider 102 is subjected to radial force to generate radial displacement, but is limited by the radial position of the adjusting rod 101. By adjusting the screwing distance of the adjusting rod 101, the radial position of the first moving slider 102 can be adjusted, and finally the axial position of the second moving slider 103 can be adjusted, and the radial adjusting precision of the first moving slider 102 is determined by the adjusting rod 101. Due to the amplification effect of the inclined surface, the axial position adjustment accuracy of the second movable slider 103 is higher than the radial position adjustment accuracy of the first movable slider 102, and the specific accuracy ratio is determined by the inclination angle of the inclined surface.
It should be emphasized that the gap adjusting device 10 can not only be screwed in by the adjusting rod 101 to perform continuous adjustment of the axial gap, but also improve the accuracy of adjusting the gap by the amplification effect of the inclined plane assembly, and simultaneously ensure the continuity and accuracy of adjusting the gap, and the motor parts do not need to be disassembled and trial measurement is not needed during continuous and accurate adjustment, thereby simplifying the process flow.
It should be noted that the motor components include, but are not limited to, the housing 1 and the end cover 2, and may also be in a structure of protecting the bearing 3, a bearing stator, and the like, and the bearing stator is specifically an axial magnetic bearing stator, that is, different motor components have various combinations, including, but not limited to, between the housing 1 and the end cover 2, between the bearing stators, between the bearing stator and the housing 1, between the end cover 2 and the protecting bearing 3, and the like, and are all suitable for the gap adjustment of the gap adjustment device 10.
In the first embodiment, the gap adjusting device 10 is fixed between the base 1 and the end cover 2 by bolts, and in this case, the first movable slider 102 and the second movable slider 103 are provided with collinear through holes in the axial direction, and the bolts are inserted from the side of the end cover 2 and fixed through the through holes in the base 1. The through hole is a mounting hole of the bolt, and the hole diameter is determined by the hole diameter of the bolt, the maximum axial adjustment clearance and the inclined plane inclination angle.
Besides, the thread diameter of the adjusting rod 101 is determined by the tightening torque of the bolt and the stress of the matching inclined plane; the diameter of the through hole in the radial direction of the first movable slider 102, which is matched with the adjustment lever 101, is determined by the adjustment lever 101 and the maximum axial adjustment gap, and the diameter of the through hole in the radial direction of the second movable slider 103, which is matched with the adjustment lever 101, is a threaded hole.
In the present embodiment, the gap adjusting device 10 can adjust the axial gap between the housing 1 and the end cap 2, and the adjusting rod 101 is disposed along the radial direction perpendicular to the axial direction. At this time, the axial end face of the first movable slider 102 is matched with the base 1, the axial end face of the second movable slider 103 is matched with the end cover 2, the first movable slider 102 and the second movable slider 103 are matched and assembled through an inclined plane, and the inclination angle of the inclined plane needs to be larger than the self-locking angle.
It should be emphasized that, in the conventional adjusting mode of the gasket or the adjusting block, after the gap measurement is completed, the end cover 2 needs to be disassembled, and then the gasket or the adjusting block needs to be adjusted; the gap adjusting device 10 is adjusted through the adjusting rod 101, the end cover 2 does not need to be disassembled after gap measurement is completed, gap adjustment can be directly carried out, axial gaps can be adjusted in the assembling process, the process flow of gap adjustment is reduced, and assembling performance is improved.

Taking the gap adjusting device 10 fixed between the base 1 and the end cover 2 by a bolt as an example, the bolt penetrates through the through hole of the first set of second moving sliding block 103 from one side of the end cover 2, then penetrates through the through hole of the first moving sliding block 102, then penetrates through the through hole of the second set of second moving sliding block 103, and then penetrates through the base 1 for fixing.
In the present embodiment, a structural form of one first moving slider 102 and two second moving sliders 103 may be adopted, and the axial position adjustment is performed through two inclined planes, because the axial gap is completed by two sets of inclined planes, so the adjustment range is wider and wider.
In the third specific embodiment, the number of the adjustment rods 101 is plural, and the plural adjustment rods 101 are arranged along the circumferential direction, and in this case, the first moving slider 102 and the second moving slider 103 are connected to each other by the adjustment rods 101 at plural positions in the circumferential direction. Taking the gap adjusting device 10 fixed between the base 1 and the end cap 2 by bolts as an example, the gap adjusting device can be matched with the end cap 2 not only in a structure that one adjusting rod 101 is matched with one second moving slide block 103, but also in a structure that two or more adjusting rods 101 are matched with one second moving slide block 103.
On the basis, taking the case that the gap adjusting device 10 is fixed between the base 1 and the end cover 2 by bolts as an example, the gap adjusting device can be modified according to the number of bolts between the base 1 and the end cover 2. When the number of bolts is plural, the gap adjusting devices 10 of the first, second, and third embodiments may be employed such that each gap adjusting device 10 corresponds to each bolt; besides, the gap adjusting devices 10 of the first, second and third embodiments may be adopted such that each gap adjusting device 10 corresponds to a plurality of bolts, and the gap adjusting device 10 of the third embodiment has a better adjusting effect because the bolts circumferentially fasten the housing 1 and the end cover 2.
The invention also provides a motor, which comprises a base 1, an end cover 2, a protective bearing 3, a thrust disc 4, a rotating shaft 5 and the like, and also comprises any one of the gap adjusting devices 10, so that the motor has all the beneficial effects of the gap adjusting device 10, and the details are not repeated.

It should be emphasized again that the gap adjustment and the position of the gap adjusting device 10 including, but not limited to, between the housing 1 and the end cap 2, between the bearing stator and the housing 1, between the end cap 2 and the protection bearing 3, etc. are all suitable for the gap adjustment of the gap adjusting device 10.
