Description

Technical Field

[0001] This utility model belongs to the field of direct drive motor technology, and specifically relates to a direct drive motor. Background Technology

[0002] A direct drive motor is a transmission device that directly converts electrical energy into linear or rotational mechanical energy. Its biggest feature is that it eliminates intermediate mechanical transmission links such as gears, lead screws, and belts.

[0003] Direct drive motors typically include direct drive linear motors, direct drive torque motors, and voice coil motors. Direct drive torque motors are often used in various rotating mechanisms. However, existing direct drive torque motors usually can only be mounted on the top or bottom of the structure that needs to rotate (i.e., the direct drive torque motor is placed on a table or suspended), which cannot be compatible with both mounting methods, resulting in poor versatility of direct drive torque motors.

[0004] Therefore, how to avoid the poor versatility of direct-drive torque motors is a technical problem that urgently needs to be solved in this field.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content

[0028] Based on the above research, this disclosure provides a direct drive motor in which, when placed on a base, the retaining ring is supported by a rotating component close to the base, and when hoisted, the support ring is supported by a rotating component away from the base, thus realizing both placement and hoisting installation methods.

[0029] The shortcomings of the above solutions are the result of the utility model inventor's practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as contributions made by the utility model inventor to this disclosure.

[0030] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0031] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0032] See Figures 1 to 4 The diagram illustrates a direct-drive motor, comprising: a base 1 on which a support platform 11 is mounted, the support platform 11 having a rotating hole 11a along its axis, and a stator (not shown) on the outer side of the support platform 11; a rotating ring 2 rotatably disposed within the rotating hole 11a, the top of the rotating ring 2 having a rotating platform 21, and the bottom of the rotating platform 21 having a moving element (not shown); and a rotating ring groove 11b on the sidewall of the rotating hole 11a, with rotating elements 12 respectively disposed at the bottom and top of the groove, and a retaining ring on the sidewall of the rotating ring 2. 22, the locking ring 22 is inserted into the rotary ring groove 11b, and the top and bottom of the locking ring 22 respectively abut against the rotary component 12; in short, the rotary table 21 is rotated by rotating the rotary ring 2 in the rotary hole 11a and cooperating with the stator and the mover. The side wall of the rotary ring 2 is provided with the locking ring 22. When placed, the locking ring is supported by the rotary component 12 close to the base 1. When hoisted, the support ring is supported by the rotary component 12 away from the base 1, so as to realize the two installation methods of placement and hoisting. The locking ring 22 is always clamped by the two rotary components 12 in the axial direction to prevent it from moving axially.

[0033] In some embodiments, the support platform 11 includes a protruding ring 11c and a cover ring 11d disposed on the base 1; the cover ring 11d is disposed on the top of the protruding ring 11c, so that the bottom of the cover ring 11d, the inner sidewall of the protruding ring 11c, and the top of the base 1 form a rotating ring groove 11b; and the rotating member 12 is disposed on the bottom of the cover ring 11d and the top of the base 1 respectively; in short, the rotating ring groove 11b is formed by the bottom of the cover ring 11d, the inner sidewall of the protruding ring 11c, and the top of the base 1, specifically the protruding ring 11c is integrally disposed on the base 1, and the cover ring 11d is detachably connected to the protruding ring 11c by bolts, so that the locking ring 22 on the sidewall of the rotating ring 2 can be installed between the cover ring 11d and the base 1.

[0034] In some embodiments, the rotating component 12 includes an annular support 12a, which is coaxially arranged with the rotating hole 11a. The annular support 12a has a plurality of placement notches 12b arranged in annular array, and a plurality of rotating columns 12c are rotatably arranged in the placement notches 12b. The axis of the rotating column 12c intersects the axis of the annular support 12a. In short, the rotating column 12c fits into the placement notch 12b. When the rotating ring 2 rotates, the rotating column 12c can well support the locking ring 22 and make only rolling friction between the locking ring 22 and the rotating ring groove 11b, thereby reducing the rotational resistance of the rotating ring 2.

[0035] In some embodiments, the rotating component 12 includes an annular support 12a, which is coaxially arranged with the rotating hole 11a. The annular support 12a has a plurality of placement notches 12b arranged in annular array, and a plurality of rotating balls (not shown in the figure) are rolled in the placement notches 12b. In short, the rotating balls generate less rolling friction than the rotating column 12c during use, but their load-bearing capacity is lower than that of the rotating column 12c. In actual use, different rotating components 12 are selected according to the load conditions.

[0036] In some embodiments, the bottom of the cover ring 11d is provided with a first placement ring groove 11e, the top of the base 1 is provided with a second placement ring groove 13, and the rotating component 12 is respectively engaged in the first placement ring groove 11e and the second placement ring groove 13; in short, the rotating component 12 is respectively embedded in the first placement ring groove 11e and the second placement ring groove 13.

[0037] In some embodiments, the width of the second placement ring groove 13 is greater than the width of the first placement ring groove 11e; in short, in order to better support the locking ring 22, the width of the second placement groove is larger, that is, the rotating component 12 inside can be a longer rotating column 12c to provide better support.

[0038] In some embodiments, a third placement ring groove 11f is provided on the inner sidewall of the cover ring 11d. The third placement ring groove 11f is adapted to install a bearing to rotatably connect the rotating ring 2. In short, in order to prevent the rotating ring 2 from radially moving, a third placement ring groove 11f is provided on the inner sidewall of the cover ring 11d to install the bearing.

[0039] In some embodiments, the bottom of the locking ring 22 is flush with the bottom of the rotating ring 2; in short, the locking ring 22 and the rotating ring 2 are integrally formed, and the fact that the bottom wall of the locking ring 22 is flush with the bottom of the rotating ring 2 can improve the strength of the locking ring 22.

[0040] In some embodiments, the bottom of the rotating platform 21 is provided with an annular protective cover 21a. The annular protective cover 21a, the rotating platform 21, the support platform 11 and the base 1 enclose a closed area for placing the stator and the moving part. In short, the annular protective cover 21a can effectively protect the stator and the moving part, and play a role in preventing dust and collision.

[0041] In some embodiments, the base 1 is square and has a plurality of connection holes 14 thereon; the rotating platform 21 is square and has a plurality of connection holes 14 thereon; in short, the connection holes 14 on the base 1 enable it to be detachably connected to the installation position by bolts, and the connection holes 14 on the rotating platform 21 enable it to be detachably connected to various mechanisms by bolts.

[0042] In the description of the embodiments of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0043] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence unless expressly indicated herein. Therefore, without departing from the teachings of the exemplary embodiments, the first element, component, region, layer, or segment discussed above may be referred to as the second element, component, region, layer, or segment.

[0044] Spatially relative terms, such as “inside,” “outside,” “below,” “below,” “down,” “above,” “up,” etc., may be used herein to describe the relationship between one element or feature illustrated in the figures and another element or feature. In addition to the orientations depicted in the figures, spatially relative terms may be intended to cover different orientations of the device in use or operation. For example, if the device in the figure is flipped, an element described as “below” or “below” other elements or features would be oriented as “above” other elements or features. Thus, the example term “below” can cover both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.

[0045] In the above discussion, unless otherwise stated, when used to describe numerical values, the terms “about,” “approximately,” “basically,” etc., indicate a change of + / - 10% in that value.

[0046] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
