[0014] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0015] like Figure 1-3 As shown, this high-precision bevel worm gear CNC rotary platform includes a platform housing 1. The platform housing 1 is equipped with an output disc shaft 2 and a gear shaft 3. The output disc shaft 2 and gear shaft 3 are connected by a tapered sleeve 4. The tapered sleeve 4 is connected to the gear shaft 3 by an adjusting screw. A large bearing 5 is provided on the output disc shaft 2. The tightness of the tapered sleeve 4 is adjusted by the adjusting screw, ensuring a zero-clearance connection between the gear shaft 3 and the output disc shaft 2. A large bevel gear 6 is located inside the platform housing 1, and a small gear 7 that meshes with the large bevel gear 6 for transmission. The gear shaft 3 has a connecting flange 8 for connecting the bevel gear 6. The bevel gear 6 has several threaded connecting holes 16 and connects to the connecting flange 8. The bevel gear 6 also has an adjusting screw hole 9, and an adjusting screw is fitted in the adjusting screw hole 9 to adjust the meshing clearance between the bevel gear 6 and the small gear 7. An adjusting shim 10 is provided between the bevel gear 6 and the connecting flange 8 to ensure that after the adjusting screw in the adjusting screw hole 9 is adjusted, there is a zero-clearance fit between the bevel gear 6 and the small gear 7, thereby improving the transmission accuracy of the large and small gears 7.

[0016] Tighten the adjusting screw in the adjusting screw hole 9. The adjusting screw abuts against the connecting flange 8, fixing the position of the pinion 7. By placing the gap measuring gauge flat and swinging it, rotate the gear shaft 3, which in turn drives the bevel gear 6 to rotate. The meshing between the bevel gear 6 and the pinion 7 is smooth. After the accuracy adjustment is accurate, remove the adjusting screw. If there is a gap between the bevel gear 6 and the pinion 7, and the meshing is not smooth, raise the position of the bevel gear 6 and tighten the adjusting screw. Repeat the operation to achieve high meshing transmission accuracy. This ensures that the meshing gap between the bevel gear 6 and the pinion 7 is consistent, achieving the best transmission accuracy and avoiding the fit tolerance caused by the original connection through the main shaft nut and flat-head pin.

[0017] like Figure 3 Therefore, the top of the gear shaft 3 is split so that the meshing connection between the gear shaft 3 and the output disc shaft 2 can be ensured after the tapered sleeve 4 is installed.

[0018] Preferably, a small bearing 11 is provided at the lower end of the gear shaft 3.

[0019] Preferably, the pinion 7 is provided with a bearing housing 12 on its exterior, and the bearing housing 12 is provided with a plurality of bearing sections 13 inside.

[0020] To elaborate further, a braking device 14 is installed on the platform housing 1. The output disc shaft 2 is braked (pneumatic or hydraulic) by the two brake pads 15 in the braking device 14, which serves to tighten the shaft, improve the service life of the overall components, and ensure good stability and consistency.

[0021] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0022] Although this document frequently uses terms such as platform housing 1, output disc shaft 2, gear shaft 3, tapered sleeve 4, large bearing 5, large bevel gear 6, small gear 7, connecting flange 8, adjusting screw hole 9, adjusting shim 10, small bearing 11, bearing seat 12, bearing part 13, braking device 14, brake pad 15, and threaded connection hole 16, the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
