The invention relates to a color wheel, in particular to a dynamic balance correction with motion balance correction and vibration correction. [Previous technology] However, this method is not only easy to cause interference in the mechanism or the optical path, and when the side of the color wheel is south When rotating at a high speed, the balance substance may also be known due to the effect of centrifugal force. After the color wheel is installed on the motor, the dynamic balance can be corrected in two ways. The first method is to load the motor or the color wheel. A balance substance (such as an adhesive) is applied to each part to perform dynamic balance correction, and 10 15 is thrown out. The second method is to drill holes in the bearing element of the color wheel to make the color wheel reach dynamic balance. In this way, if the power is not properly controlled during drilling, it will easily cause the motor to support the The bearing of the bearing element is damaged ', and the metal powder produced by drilling will easily pollute and scratch the coating surface of the filter of the color wheel. As shown in FIG. 1, in order to improve the above defect, a color wheel with a dynamic balance groove (new patent No. 487178) was proposed. The color wheel includes a load bearing element 1 and a plurality of color wheels fixed to the load bearing element. A filter 2 between a motor 3. The bearing element has an outer surface 10 away from the motor 3, a bottom surface 102 facing the motor 3 and capable of pressing against the filter 2, and an annular groove 1 formed on the outer surface 101. 〇3. In this way, when the color wheel is fixed on the motor 3, if the color wheel is unbalanced during rotation, the corrector can fill a balance object in the annular groove 103 to improve Correct the dynamic balance of the color wheel. 20 5 10 15 20 1243954 Although 'the color wheel can be filled with a balance substance, and b / hi has the purpose of dynamic balance 103' shape groove 103, but in actual correction, use 0 color this color The wheel has the following shortcomings: The use of B-inch,, / corrector accidentally made the balance material filled by people high ring groove 1Q3h 'may still cause interference on the optical path. ㈣ Second, the annular groove 103 is located away from the outer surface of the 101 motor 3,-but after the balance substance is filled in the annular groove 〖03, the + balance substance will cause the whole body to be stupid. The branch is extended away from the # center position of the motor 3, that is, away from the main thunder, Μ Μ J to produce electromagnetic spreading and mechanical vibration ^, so even if the color wheel can complete the dynamic balance correction ... ^ color wheel Therefore, it is difficult to correct the overall vibration, which affects the production efficiency. [Content of the invention]: The purpose of the present invention is to provide a method that does not cause interference on the optical path and can easily perform dynamic balance and vibration correction. Dynamically balance the color wheel of the positive groove. The color wheel with dynamic balance correction grooves of the present invention can be easily reached, and includes a light-transmitting sheet unit 'and a bearing element. The load bearing element can be mounted on the motor, the load bearing element has a load plane capable of bearing the light beam,-opposite to the load plane and facing the bottom surface of the motor, and-formed on the bottom surface and The continuous recessed correction groove is dreamed that when the correction groove is filled with a balance substance, no light path will be generated, and dynamic balance and vibration correction can be easily performed. [Embodiment] 6 1243954 The foregoing and other technical contents, features, and effects of the present invention will be clearly understood in the following detailed description of the preferred embodiment with reference to the drawings. > See FIG. 23. The color wheel with dynamic balance correction grooves of the present invention, a preferred embodiment, is vibratingly disposed on a motor 100 having a shaft 110 and a rotating shaft 120. The color wheel includes: A filter unit 10, a carrying element 20, a gland 30, a washer 40, and three bolts 50. ίο 15 The crossing light unit 10 has a plurality of light plates n,-a central hole 12 defined by the inner periphery of the light-shielding plate 11 such as β-xuan, and a filter such as 21 Glue into one integral limiter J 3. The bearing element 20 is fixed on the rotating hub 11 and the rotating shaft 120, and can rotate synchronously with the rotating number 11G and the rotating shaft 12G. The bearing το member 20 has-can carry the light-transmitting unit The bearing plane 2 extends upwardly from the bearing plane 21 and can pass through the flange 4 22 of the middle q 12,-opposite to the bearing plane 21 and facing the bottom surface 23 'of the motor rigid and-formed on the A circular-shaped correction groove 2 on the bottom 23, when the filter unit U) is installed on the bearing plane 21 of the bearing element 20, the screws ☆ 5G can pass through the pressure in order Cover the three through holes η and the center hole 12 ′, and fix the cover 30 to the bearing element ，, so that the spacer 40 is sandwiched between the grinding cover 30 and the stopper 13 And make the light-like sheet 1] force I and 疋 on the other bearing plane h ^ xtb of the bearing element. The invention generates unbalanced information during rotation, and the corrector can fill in the correction groove 24 The balance object f (not shown in the figure, for example, 20 1243954 balance soil or balance glue) is used to improve and correct the dynamic balance of the present invention. Through the above description, the advantages of the present invention can be summarized as follows: 1. The correction recess # 24 of the present invention is formed on the bottom surface 23 of the load bearing element ，, and the projected light is projected through the travel track of the trowels u. It does not pass through the correction groove 24 at all, so even if the corrector accidentally makes the filled balance material slightly higher than the correction groove 24, the present invention will not cause the problem of optical path interference as in the conventional art. Ίο 15 2. The correction groove 24 of the present invention is formed on the bottom surface 23 of the carrying it member 20 near the motor 100. Therefore, after the balance substance is filled in the correction groove 24, the balance substance of the present invention The amount of displacement that lifts the overall center of gravity upward is far less than the conventional technique, and it can be closer to the heavy coin position of the motor #, which can be more sinful to the main source area of the motor that generates electromagnetic vibration and mechanical expansion, Therefore, compared with the conventional technique, the present invention can more easily correct and eliminate the overall vibration, and improve the production efficiency. The color wheel with the dynamic balance correction groove of the present invention not only does not cause interference on the optical path when filling the balance substance, but also can easily perform dynamic balance and vibration correction, and can improve production efficiency. Can achieve the purpose of invention. f 隹 The above are only the preferred embodiments of the present invention. When the scope of implementation of the present invention cannot be limited by this, that is, the simple equivalent changes and modifications made in accordance with the scope of the patent application and the content of the creative specification , Are still within the scope of the invention patent. 20 1243954 [Brief description of the drawings] FIG. 1 is a conventional partial cross-sectional view of a combination of a color wheel and a motor; FIG. 2 is an exploded perspective view of a preferred embodiment of a color wheel with a dynamic balance correction groove and a motor ; And FIG. 3 is a partial cross-sectional view of the combination of the preferred embodiment and the motor. 1243954 [Brief description of the main components of the diagram] 1 Carrying element 101 Outer surface 102 Bottom surface 103 Ring groove 2: Filter 3 s Motor 100 Motor 110 Rotating hub 120 Rotating shaft 10 Filter unit 11 Filter 12 Center hole 13 Stopper 20 Carrying element 21 Carrying plane 11.
