Problems solved by technology

However, in the process of drilling the balance hole 201, if the force is not properly controlled, it is very easy to cause damage to the bearing supporting the carrier 2 inside the motor 1. In addition, the metal powder generated by drilling may also pollute the motor. and scratch the coating surface of the sector filter 4
[0005] 2. The fan-shaped filters 4 are glued together on the carrier 2. Therefore, when the color wheel set is assembled, if one of the fan-shaped filters 4 is damaged or of poor quality, the color wheel set will not It is impossible to carry out maintenance by individually replacing the fan-shaped filter 4, thereby causing the overall structure to be scrapped, thus not only wasting parts, but also increasing the production cost
[0009] 3. After the color wheel group is assembled, the dynamic balance may still be poor due to the factors of the motor 6, and it is difficult to perform dynamic balance correction

Embodiment Construction

[0021] The foregoing and other technical contents, features, and effects of the present invention will be clearly understood in the following detailed description of a preferred embodiment with reference to the drawings.

[0022] Refer to Figure 4 , 5, and 6 are preferred embodiments of the color wheel set of the present invention. The color wheel set can be installed on a motor 100 having a rotating shaft 110 and a rotor 120. The color wheel set includes: a rotating hub 10, a filter unit 20, a gland 30, a gasket 40, a joint unit 50, three bolts 60, and a balance material 70.

[0023] The rotating hub 10 is installed on the rotating shaft 110 and the rotor 120 of the motor 100, and the rotating hub 10 can be driven by the motor 100 to rotate around an axis.

[0024] The filter unit 20 has a number of filters 21 that can be grouped together, and a central hole 22. Each of the filters 21 has a top surface 211, a bottom surface 212 opposite to the top surface 211, an outer periphera...

Abstract

A color wheel group, including: the running hub, the filter unit that is with several grouping filter slice, the gland halving with the running hub, the spacing block setting on the filter, the joint unit of the spacing groove on one of the running hub and the gland, the spacing block with a inside face and a outside face opposites to it, the first side-end face between the inside and outside face, the second side-end face between the inside and outside face and opposites to the first side-end face, the groove-way extends from the first side-end face to the second side-end face; the gland halving with the running hub, the filter locates on the running hub, the spacing block embeds in the space groove.

Description

Technical field [0001] The invention relates to a color wheel set, in particular to a color wheel set that does not overflow glue during assembly and is easy to adjust dynamic balance. Background technique [0002] As shown in Figure 1, there is a color wheel set (US Patent No. 5,868,482), which includes a motor 1, a carrier installed on the shaft of the motor 1, and a glue coated on the carrier 2. The layers 3 and three are adhered to the adhesive layer 3 to form a circular fan-shaped filter 4 and a clamping ring 5 that can cover the bonded area of ​​the fan-shaped filter 4. In this way, the motor 1 can drive the fan-shaped filter 4 to rotate at a high speed, so that the light projected through the fan-shaped filter 4 can finally generate an image on a screen (not shown). [0003] Although the fan-shaped filter 4 of the color wheel set can be adhered to the carrier 2 and driven by the motor 1, in actual production and use, the color wheel set has the following shortcomings: [0...
