Description
本發明係關於一種馬達及其定位環，特別是一種可避免定位環與馬達軸管緊配合，而造成馬達軸管變形之馬達及其定位環。The invention relates to a motor and a positioning ring thereof, in particular to a motor and a positioning ring thereof, which can avoid the deformation of the positioning ring and the motor shaft tube and cause deformation of the motor shaft tube.
傳統馬達構造係如第1圖所示，該馬達8包含設有一基座81、一定子組82及一轉子83，該基座81具有一軸管811，該軸管811外設有該定子組82，且該軸管811內則設有一軸承812，該轉子83係可旋轉地設置於該基座81之軸管811，並以一轉軸831伸入貫穿該軸承812。其中，為了能於馬達運轉過程中有效定位該軸管811內之軸承812，多會選擇另設有一定位環84，以使該定位環84可緊配合裝設於該軸管811內。The conventional motor structure is as shown in FIG. 1. The motor 8 includes a base 81, a certain subset 82, and a rotor 83. The base 81 has a shaft tube 811, and the stator tube 811 is provided with the stator assembly 82. A bearing 812 is disposed in the shaft tube 811. The rotor 83 is rotatably disposed on the shaft tube 811 of the base 81 and extends through the bearing 812 by a rotating shaft 831. In order to be able to effectively position the bearing 812 in the shaft tube 811 during the operation of the motor, a positioning ring 84 is additionally provided to enable the positioning ring 84 to be tightly fitted in the shaft tube 811.
然而，因傳統定位環84之外徑略大於該軸管811之內徑，故該定位環84多係以其全周面緊配於該軸管811之內周壁，以在長時間的使用之下，極容易因該定位環84與軸管811之間的緊配裝設，而迫使該定位環84不斷朝該軸管811之徑向方向擠壓，嚴重造成該軸管811之擴張、變形，以致該軸管811內部裝設之軸承812等零件產生鬆動，而可能在該轉軸831旋轉時產生震動，進而使習知馬達8產生巨大噪音並降低其使用壽命。However, since the outer diameter of the conventional positioning ring 84 is slightly larger than the inner diameter of the shaft tube 811, the positioning ring 84 is closely fitted to the inner peripheral wall of the shaft tube 811 with its full circumference to be used for a long time. In the following, it is extremely easy for the positioning ring 84 to continuously press in the radial direction of the shaft tube 811 due to the tight fitting between the positioning ring 84 and the shaft tube 811, which seriously causes the expansion and deformation of the shaft tube 811. Therefore, parts such as the bearing 812 installed inside the shaft tube 811 are loosened, and vibration may occur when the rotating shaft 831 rotates, thereby causing the conventional motor 8 to generate a large noise and reduce the service life thereof.
請再參照第2圖所示，其係揭示另一種習知馬達定位環構造，該馬達定位環91係呈緊配合裝設於一軸管92內，以將一軸承93限位於該軸管92內部之預定位置。其中，該馬達定位環91中央具有可供一心軸94穿設的一中孔911，外周面則設有至少一個以上的迴流孔912，該迴流孔912係對應該軸管92的內壁，並且是兩面貫穿的。此外，該軸管92底部還另塞合一頂心蓋95，且該頂心蓋95與軸承93之間更夾掣有一扣片96，以由該扣片96扣持該心軸94，使該心軸94可頂撐於該頂心蓋95旋轉而不脫出。Referring to FIG. 2 again, another conventional motor positioning ring structure is disclosed. The motor positioning ring 91 is tightly fitted in a shaft tube 92 to limit a bearing 93 to the inside of the shaft tube 92. The predetermined location. Wherein, the center of the motor positioning ring 91 has a middle hole 911 through which a mandrel 94 is disposed, and the outer peripheral surface is provided with at least one or more return holes 912 corresponding to the inner wall of the shaft tube 92, and It runs through both sides. In addition, a bottom cover 95 is further inserted into the bottom of the shaft tube 92, and a buckle piece 96 is further sandwiched between the top cover 95 and the bearing 93 to hold the mandrel 94 by the buckle 96. The mandrel 94 can be supported against the top cover 95 to rotate without coming off.
縱使，藉由該馬達定位環91外周面所開設之迴流孔912，可形成供潤滑油液回流循環的管道，以防止潤滑油液外溢流失，從而達到保護馬達避免其心軸94與軸承93磨損，並提升馬達使用壽命之功效。Even if the return hole 912 of the outer peripheral surface of the motor positioning ring 91 is formed, a conduit for circulating back the lubricating oil can be formed to prevent the lubricating oil from overflowing, thereby protecting the motor from the wear of the mandrel 94 and the bearing 93. And improve the life of the motor.
但是，該迴流孔912僅佔該馬達定位環91之一小部分，故於該馬達定位環91裝設於該軸管92內時，仍舊是以幾近全周面之型態緊配於該軸管92之內周壁，因此，該一小部份之迴流孔912仍無法提供該馬達定位環91適當之變形空間。如此一來，習知馬達定位環構造仍無法改善如上所述軸管擴張、變形之問題，以致習知馬達在長時間的運轉下，仍然會使該軸管92內部裝設之軸承93、扣片96等零件產生鬆動，而在該心軸94旋轉時產生震動等缺失，進而縮短習知馬達的使用壽命。However, the return hole 912 only occupies a small portion of the motor positioning ring 91. Therefore, when the motor positioning ring 91 is mounted in the shaft tube 92, it is still closely matched to the shape of the nearly full circumference surface. The inner peripheral wall of the shaft tube 92, therefore, the small portion of the return hole 912 still does not provide the proper deformation space of the motor positioning ring 91. As a result, the conventional motor positioning ring structure still cannot improve the problem of the expansion and deformation of the shaft tube as described above, so that the conventional motor still has the bearing 93 and the buckle installed inside the shaft tube 92 under the long-term operation. The parts such as the sheet 96 are loosened, and when the mandrel 94 rotates, vibration or the like is lost, thereby shortening the service life of the conventional motor.
有鑑於此，確實有必要發展一種可以避免軸管徑向擴張、變形之定位環，並將該定位環適用於馬達之中，以解決如上所述之各種問題。In view of this, it is indeed necessary to develop a positioning ring that can avoid radial expansion and deformation of the shaft tube, and apply the positioning ring to the motor to solve various problems as described above.

請一併參閱第4及5圖所示，該定位環4設置於該軸管11內，用以定位該軸管11內之內裝組件[如第3圖所示之軸承12及扣持片13]。其特徵在於：該定位環4中央具有一穿孔41，該穿孔41較佳係用以供該轉軸22穿伸；且，該定位環4外周面間隔設有數凹部42及數凸部43，任一凹部42至該定位環4中心的最短距離[即如第5圖所示之第一距離D1]略小於或等於該軸管11內壁至軸管11中心的最短距離[即如第5圖所示之軸管內半徑R]，以特別在任一凹部42與軸管11內壁之間形成有一間距w為佳，藉此係能透過該間距w降低該定位環4外周面與軸管11內壁的接觸面積，進而能略為降低該定位環4與軸管11的緊配程度；再者，任一凸部43至該定位環4中心的最短距離[即如第5圖所示之第二距離D2]則略大於該軸管11內壁至軸管11中心的最短距離[即如第5圖所示之軸管內半徑R]，以特別使任一凸部43可緊配抵頂於該軸管11內壁為佳，藉此係能將該定位環4緊配塞合於該軸管11內，並用以定位該軸承12。As shown in FIGS. 4 and 5, the positioning ring 4 is disposed in the shaft tube 11 for positioning the inner component of the shaft tube 11 [such as the bearing 12 and the fastening piece shown in FIG. 13]. The locating ring 4 has a through hole 41 in the center thereof, and the through hole 41 is preferably used for the rotation of the rotating shaft 22; and the outer circumferential surface of the positioning ring 4 is provided with a plurality of concave portions 42 and a plurality of convex portions 43. The shortest distance from the recess 42 to the center of the positioning ring 4 [ie, the first distance D1 as shown in FIG. 5] is slightly smaller than or equal to the shortest distance from the inner wall of the shaft tube 11 to the center of the shaft tube 11 [ie, as shown in FIG. 5 The inner radius R of the shaft tube is preferably formed to have a spacing w between any of the recesses 42 and the inner wall of the shaft tube 11, whereby the outer circumferential surface of the positioning ring 4 and the inner tube 11 can be lowered through the spacing w. The contact area of the wall can further reduce the tightness of the positioning ring 4 and the shaft tube 11; further, the shortest distance from any convex portion 43 to the center of the positioning ring 4 [ie, the second as shown in FIG. 5 The distance D2] is slightly larger than the shortest distance from the inner wall of the shaft tube 11 to the center of the shaft tube 11 [ie, the inner radius R of the shaft tube as shown in Fig. 5), so that any convex portion 43 can be tightly fitted against the top. The inner wall of the shaft tube 11 is preferred, whereby the positioning ring 4 can be tightly fitted into the shaft tube 11 and used to position the bearing 12.
舉例而言，當該軸管11與定位環4是為相互緊配之圓形環體時，該軸管11內壁至軸管11中心的最短距離即為第5圖所示之軸管11內半徑R。其中，該第一距離D1即為該第二距離D2減去該間距w所獲得之長。經此，該定位環4乃是以能緊配合該軸管11之內徑，並以數凹部42略減少該定位環4外壁與軸管11內壁的接觸面積為佳。For example, when the shaft tube 11 and the positioning ring 4 are circular rings that are closely fitted to each other, the shortest distance from the inner wall of the shaft tube 11 to the center of the shaft tube 11 is the shaft tube 11 shown in FIG. Inner radius R. The first distance D1 is the length obtained by subtracting the distance w from the second distance D2. Therefore, the positioning ring 4 is preferably capable of tightly fitting the inner diameter of the shaft tube 11, and the contact area of the outer wall of the positioning ring 4 and the inner wall of the shaft tube 11 is slightly reduced by the number of recesses 42.
請續參閱第6圖所示，任一凹部42在該定位環4的徑向截面上係形成有一弧長A1，各該凹部42之弧長A1係可加總為一凹部總弧長；且，任一凸部43在該定位環4的徑向截面上亦形成有一弧長A2，各該凸部43之弧長A2則可加總為一凸部總弧長，以由該數凹部42之總弧長[即凹部總弧長]及數凸部43之總弧長[即凸部總弧長]共同形成該定位環4之外周長，特別係使該數凹部42之總弧長佔該定位環4外周長的三分之一至三分之二為佳。Referring to FIG. 6 , any recess 42 is formed with an arc length A1 in a radial section of the positioning ring 4 , and an arc length A1 of each of the recesses 42 may be added to a total arc length of the recess; Any of the convex portions 43 is formed with an arc length A2 in the radial cross section of the positioning ring 4, and the arc length A2 of each of the convex portions 43 may be added to a total arc length of the convex portion to be used by the plurality of concave portions 42. The total arc length [ie, the total arc length of the concave portion] and the total arc length of the plurality of convex portions 43 [ie, the total arc length of the convex portion] collectively form the outer circumference of the positioning ring 4, in particular, the total arc length of the number of concave portions 42 is occupied. One third to two thirds of the outer circumference of the positioning ring 4 is preferred.
特別地，該數凹部42及數凸部43係可選擇等數量分佈於該定位環4外周面，以使該數凹部42與數凸部43之總弧長在該定位環4外周面佔有相等比例為佳。另一方面，該數凹部42之各弧長可以選擇為相互等長，或該數凹部42可選擇具有兩種或兩種以上不等長之弧長分佈；同樣地，該數凸部43之各弧長可以選擇為相互等長，或該數凸部43可選擇具有兩種或兩種以上不等長之弧長分佈。In particular, the number of concave portions 42 and the plurality of convex portions 43 may be equally distributed on the outer circumferential surface of the positioning ring 4 such that the total arc length of the plurality of concave portions 42 and the plurality of convex portions 43 occupy the same on the outer circumferential surface of the positioning ring 4. The ratio is better. On the other hand, the arc lengths of the number of recesses 42 may be selected to be equal to each other, or the number of recesses 42 may have an arc length distribution of two or more unequal lengths; likewise, the number of protrusions 43 Each arc length may be selected to be equal to each other, or the number of convex portions 43 may be selected to have an arc length distribution of two or more unequal lengths.
本實施例之定位環4係如第6圖所示設有四個凹部42及四個凸部43，各該凹部42與各該凸部43係間隔設置於該定位環4外周面。再者，各該凹部42皆具有相等長的一弧長A1，以由該四個凹部42之弧長A1加總為凹部總弧長，該凹部總弧長係佔該定位環4外周長的二分之一；各該凸部43亦皆具有相等長的一弧長A2，以由該四個凸部43之弧長A2加總為凸部總弧長，且該凸部總弧長亦佔該定位環4外周長的二分之一。As shown in FIG. 6, the positioning ring 4 of the present embodiment is provided with four concave portions 42 and four convex portions 43, and each of the concave portions 42 and the convex portions 43 are spaced apart from each other on the outer circumferential surface of the positioning ring 4. Furthermore, each of the recesses 42 has an arc length A1 of equal length, so that the arc length A1 of the four recesses 42 is totaled as the total arc length of the recess, and the total arc length of the recess occupies the outer circumference of the positioning ring 4. One-half of each of the convex portions 43 also has an arc length A2 of equal length, so that the arc length A2 of the four convex portions 43 is added to the total arc length of the convex portion, and the total arc length of the convex portion is also It accounts for one-half of the outer circumference of the positioning ring 4.
藉此，透過該數凸部43間隔且平均分佈於該定位環4外周面，係能提供該定位環4較勻稱之緊配支撐效果，以兼顧該定位環4緊配合裝設於該軸管11內，達到用以定位該軸承12之功效；再者，更可透過平均分佈的數凹部42有效減少該定位環4外周面與軸管11內壁的接觸面積，從而降低該定位環4朝該軸管11軸向方向擠壓，而造成該軸管11徑向擴張、變形之情形。此外，當該定位環4緊配裝設於該軸管11內，並受該軸管11限位時，透過該數凹部42與數凸部43的間隔排列，係能容許該數凸部43在與軸管11內壁的緊配過程適時朝向相鄰之凹部42擴張，以由該數凹部42提供該定位環4適當變形空間，方可避免該數凸部43被限制成僅可朝外擠壓，而衍生該軸管11受力變形之疑慮。Therefore, the plurality of convex portions 43 are spaced apart and evenly distributed on the outer circumferential surface of the positioning ring 4, so as to provide a relatively well-fitting supporting effect of the positioning ring 4, so that the positioning ring 4 is tightly fitted to the shaft tube. 11 , the effect of positioning the bearing 12 is achieved; furthermore, the evenly distributed number of recesses 42 effectively reduces the contact area of the outer circumferential surface of the positioning ring 4 with the inner wall of the shaft tube 11 , thereby reducing the positioning ring 4 toward The shaft tube 11 is pressed in the axial direction to cause the shaft tube 11 to expand and deform radially. In addition, when the positioning ring 4 is tightly fitted in the shaft tube 11 and is limited by the shaft tube 11, the number of the convex portions 43 is allowed to be transmitted through the interval between the number of concave portions 42 and the plurality of convex portions 43. The fitting process with the inner wall of the shaft tube 11 is timely expanded toward the adjacent concave portion 42 to provide a suitable deformation space of the positioning ring 4 by the number of concave portions 42 so as to prevent the number of convex portions 43 from being restricted to be outward only Squeeze, and the bearing of the shaft tube 11 is deformed.
以上，僅是本發明揭露的一較佳實施態樣，該領域中具有通常知識者應可在相同技術概念下加以應用，並維持任一凹部42與軸管11內壁之間形成有間距w，且任一凸部43可緊配抵頂於該軸管11內壁，甚至該數凹部42之總弧長係佔該定位環4外周長的三分之一至三分之二即可。The above is only a preferred embodiment of the present invention. Those skilled in the art should be able to apply the same technical concept and maintain a spacing between any recess 42 and the inner wall of the shaft tube 11. And any convex portion 43 can be tightly fitted against the inner wall of the shaft tube 11, and even the total arc length of the plurality of concave portions 42 can be between one third and two thirds of the outer circumference of the positioning ring 4.
此外，本發明之馬達於實作配置該定位環4時，亦可以如第7圖所示，選擇於該軸管11內容置有一上滾珠軸承12a、一下滾珠軸承12b、一扣持件13、一上墊片14a、一下墊片14b及一彈性件15，並於該上、下滾珠軸承12a、12b之間設有該定位環4，且使該定位環4位於該彈性件15與下滾珠軸承12b之間為佳。再者，該扣持件13係抵接於該轉軸22之扣持槽221，且使該下墊片14b位於該下滾珠軸承12b與扣持件13之間；另，該上墊片14a則位於該上滾珠軸承12a與彈性件15相抵接處，且該彈性件15之二端係分別抵接該上墊片14a及定位環4。藉此，不僅可透過該定位環4定位該上、下滾珠軸承12a、12b，亦可如前所述以該定位環4之數凹部42提供該定位環4適當變形空間，方可避免該數凸部43被限制成僅可朝外擠壓，進而達到防止該軸管11受定位環4擠壓而變形之功效。In addition, when the positioning ring 4 is configured in the motor of the present invention, as shown in FIG. 7, the upper ball bearing 12a, the lower ball bearing 12b, and the holding member 13 may be disposed on the shaft tube 11. An upper spacer 14a, a lower spacer 14b and an elastic member 15, and the positioning ring 4 is disposed between the upper and lower ball bearings 12a, 12b, and the positioning ring 4 is located at the elastic member 15 and the lower ball It is preferred between the bearings 12b. In addition, the holding member 13 abuts against the holding groove 221 of the rotating shaft 22, and the lower spacer 14b is located between the lower ball bearing 12b and the holding member 13; The upper ball bearing 12a is in contact with the elastic member 15, and the two ends of the elastic member 15 abut the upper spacer 14a and the positioning ring 4, respectively. Thereby, the upper and lower ball bearings 12a, 12b can be positioned not only through the positioning ring 4, but also the appropriate deformation space of the positioning ring 4 can be provided by the number of recesses 42 of the positioning ring 4 as described above. The convex portion 43 is restricted to be pressed only outward, thereby achieving the effect of preventing the shaft tube 11 from being deformed by being pressed by the positioning ring 4.
承上，當本發明馬達於實作配置該定位環4時，不僅可適用於如上述實施例之馬達型態，該馬達之型態特徵係該定子組3緊配於該軸管11外周壁；甚至，更可以選擇適用於如第8圖所示之馬達型態，該馬達之型態特徵係該定子組3鎖接於該基座1。藉此，係可在該軸管11外周壁未緊套該定子組3的情況下，同樣可達到使該軸管11能不受該定位環4之擠壓而變形之功效。The motor of the present invention is not only applicable to the motor type as in the above embodiment, but the type of the motor is that the stator assembly 3 is tightly fitted to the outer peripheral wall of the shaft tube 11. Even more, the motor type as shown in FIG. 8 can be selected, and the type of the motor is that the stator set 3 is locked to the base 1. Thereby, in the case where the outer peripheral wall of the shaft tube 11 is not tightly sheathed, the shaft tube 11 can be deformed without being deformed by the positioning ring 4.
綜上所述，本發明馬達及其定位環之主要特徵在於：藉由該定位環4外周面所形成之數凹部42，係能減少該定位環4緊配裝設於該軸管11內壁的接觸面積，以降低該定位環4朝該軸管11軸向方向的擠壓施力，從而避免該軸管11產生徑向擴張，而造成其內部零件鬆動之情形。如此一來，本發明馬達不僅能以該定位環4之數凸部43持續維持與該軸管11的緊配限位效果；同時，本發明馬達更能以該定位環4之數凹部42降低軸管11徑向擴張之情形，進而避免該軸管11內承裝之零件鬆動，以能降低該轉軸22旋轉時之震動及噪音，達到提升馬達使用壽命之功效。In summary, the main feature of the motor and the positioning ring of the present invention is that the number of the recesses 42 formed by the outer peripheral surface of the positioning ring 4 can reduce the positioning ring 4 to fit tightly on the inner wall of the shaft tube 11. The contact area is to reduce the pressing force of the positioning ring 4 toward the axial direction of the shaft tube 11, thereby avoiding the radial expansion of the shaft tube 11 and causing the internal parts to loosen. In this way, the motor of the present invention can not only maintain the matching limit effect with the shaft tube 11 by the number of the convex portions 43 of the positioning ring 4; meanwhile, the motor of the present invention can be lowered by the number of the recesses 42 of the positioning ring 4. When the shaft tube 11 is radially expanded, the parts contained in the shaft tube 11 are prevented from loosening, so as to reduce the vibration and noise when the shaft 22 rotates, thereby improving the service life of the motor.
