As shown in fig. 1 to 4, the embodiment provides a rotating device for stage lamps, which includes a base 10, a circular boss 20 disposed on the base 10, a first bearing 30 coaxially sleeved on an outer wall of the circular boss 20, a second bearing 40 coaxially embedded on an inner wall of the circular boss 20, a central rotating shaft 60 coaxially fixed on an inner ring of the second bearing 40, and three effect discs, wherein the three effect discs are respectively fixed on the central rotating shaft 60, an outer ring of the first bearing 30, and an outer ring of the second bearing 40, and the three effect discs are located on three different planes. The three-shaft-drive-type electric motor driving device further comprises three belt pulleys 701 which are coaxially fixed on the outer wall of the outer ring of the central rotating shaft 60 and the first bearing 30 and the upper end face of the second bearing 40 respectively, three effect discs are connected with the corresponding outer ring of the central rotating shaft 60, the outer ring of the first bearing 30 and the outer ring of the second bearing 40 through the corresponding belt pulleys 701 respectively, the three-shaft-drive-type electric motor driving device further comprises three motors and three transmission belts 702, and each belt pulley 701 is in transmission connection with the corresponding motor through.

The connection mode between the transmission belt 702, the pulley 701 and the motor is the prior art, i.e. the prior belt transmission structure, and is not described herein again.

The working principle is as follows: the three motors drive the corresponding belt pulleys 701 to rotate through the corresponding transmission belts 702 respectively, the three belt pulleys 701 drive the corresponding three effect discs to coaxially rotate respectively, the structure is compact, and the rotation of the three effect discs does not interfere with each other. The belt pulley 701 is adopted for transmission, so that the operation is stable, the noise is low, the vibration is low, and the device is suitable for use scenes of stage lamps and accurate control of projection imaging of the stage lamps.

To improve the rotational accuracy of the effect tray, the motor is a stepper motor 703.

The effect discs are disc-shaped, and each effect disc is coaxially fixed to a corresponding belt pulley 701.

The three effect discs are a pattern disc 503, a water wave disc 502 and a color chip disc 501. The color disc 501 switches light colors, the water wave disc 502 controls light effects, the pattern disc 503 fixes hollow patterns, and light is projected according to the hollow patterns.

In order to improve the light projection effect, the three effect discs are respectively a color chip disc 501, a water wave disc 502 and a pattern disc 503 from bottom to top. The lower color film disc 501 is the effect disc closest to the light source of the lamp, the color which is not needed is filtered, the pattern disc 503 is farthest away from the light source, the light source can be prevented from emitting light, a large amount of light with needed color is filtered out through the pattern disc 503, and the situation that the projection brightness of the stage lamp light is low due to the fact that the light with the needed color is shielded is avoided.

In order to avoid friction between the outer ring of the first bearing 30 and the base 10 during rotation, the outer wall of the circular boss 20 is coaxially provided with an annular flange 80, and the upper end surface of the annular flange 80 is lower than the upper end surface of the circular boss 20. First bearing 30 is great for second bearing 40 volume, and is heavier, and when being fixed in the belt pulley 701 drive first bearing 30 rotation of first bearing 30 outer lane, the easy base 10 of first bearing 30 outer lane takes place the friction, supports first bearing 30 inner circle through setting up cyclic annular flange 80, makes first bearing 30 outer lane unsettled, and it leads to wearing and tearing and rotation unsmooth to rub with base 10 when avoiding first bearing 30 to rotate.

In order to realize the matching of the transmission device and the light source of the stage lamp, the stage lamp further comprises a support frame 90 provided with a light outlet, the base 10 is fixed, the motor is respectively arranged on the support frame, and the light outlet is positioned below the effect disc. The light source is arranged at the light outlet to emit light, and the light projection with specific effect is realized through each effect disc.

To reduce friction, the first bearing 30 and the second bearing 40 are ball bearings. Ball bearings provide minimal friction relative to other similar bearing structures.

The above embodiments are only some of the preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
