The rotation stop portion 14c is at least one stop pin provided on the rotating shaft 12, and the engaging portion 21c is at least one rotation stop groove provided on the filter and optical element 2, the rotation stop pin It closely corresponds to the position and shape of the anti-rotation groove. The filter element 2〇c is sleeved on the '_axis 12' to stop the stoppage, and the tight fit therebetween limits the rotational movement of the filter element 20c relative to the rotating shaft 12. In this embodiment, the rotation of the stop beam 7G member 20c relative to the rotating shaft 12 is restricted by the cooperation of the plurality of rotation preventing pins and the rotation preventing groove. The rotation preventing pin has a square column shape and is extended along the radial direction. The shaft body 16 is disposed on the shaft body 16 . Of course, it is possible to provide other types of stop pins, or a greater number of stop pins as the stop portion 14c. The calendering element 2〇c of the present embodiment comprises an annular transparent substrate%, and the surface of the naive transparent substrate 26 is divided into a plurality of sectors 27, and each of the sectors 27 has a different tantalum film 28 to form a ring. Shaped light area. The shaped transparent substrate 26 is made of glass, although other transparent materials of the shape I may be used. A stop rotation is provided at the center hole of the annular glass; as the engaging portion 21c. In the present embodiment, the transparent substrate 26 is provided with four sectors of 13 (S) 1334956, and a filter film 28 for filtering out red, green, blue and white light is respectively bonded. When the color wheel 300 is in operation, the calendering element 2〇c rotates at a speed of 7200 rpm per minute, and the filter element 20c rubs against the air to vibrate, vibrates the shirt; the light effect is caused and the noise is caused. . To this end, the present embodiment provides a damper element 55 between the filter element 20c and the motor cover to reduce the vibration of the filter element 20c. The damper element 55 is an annular sheet, and the sleeve a is the same as the motor cover, and has the same size as the central portion of the filter element 20c, and is also provided with the rotation stop. The matching gap (not shown). The damper element 55 can be made of rubber, silicone or plastic material, and the embodiment uses a rubber material. When the color wheel 30 is mounted, the damper member 55 is first fitted into the rotating shaft 12, and the notch is aligned with the rotation preventing pin. The filter element 20c is then nested and the anti-rotation groove is aligned with the stop pin. The spring and the spacer are inserted into the spring, and the filter element is fixed to the motor 10 by locking the shaft retaining ring. The color wheel of the above embodiment utilizes a mechanical structure to generate a mechanical force to fix the filter element to the motor. Compared with the conventional color wheel, the installation process does not require a heating process to prevent the motor from being damaged by heat. If a component is found to be damaged after installation, simply remove the lock to separate the parts, replace the damaged parts, and recycle the functional parts. The process can be reworked. It will be understood that the color wheel of the first embodiment and the second embodiment described above may also include a damper element to reduce the vibrational motion of the filter element. 14 ^^4956 It can be understood that the color wheel can simultaneously collect the clearing elements _ _ in the upper 4 real financial formula, can be transferred to other structural combinations that can limit the 7G pieces of the scale in the hot county . The cooperation of the smuggling (10) locking portion and the locking member is not limited to the above-mentioned formula, and other locking combinations that can compress the spring can be used.
