Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

All the electrical parts in the present case are connected with the power supply adapted to the electrical parts through a wire, and an appropriate controller and an appropriate encoder should be selected according to the actual situation to meet the control requirement, and the specific connection and control sequence should be determined.

Example (b): according to the attached figures 1-3 in the specification, the speed reducer special for saw cutting comprises a speed reducer box body 2, an input shaft 3 and an output shaft 13, wherein the speed reducer box body is manufactured by adopting a casting process or a welding process, and the strength is ensured. The box mounting means is diversified. One end of an inner hole of the input shaft 3 is matched with a motor shaft, the other end of the inner hole is in flat key connection with a small bevel gear of a first-stage bevel gear component 4 to realize interference fit, and the large bevel gear and the small bevel gear of the first-stage bevel gear component are in meshing transmission through a constant-top-clearance spiral bevel gear. The first-stage bevel gear assembly 4, the second-stage cylindrical helical gear assembly 5 and the third-stage cylindrical helical gear assembly 6 form gear transmission through tooth surface meshing, gear parameters can be matched according to different speed ratios, the output rotating speed can be adjusted according to different requirements, the precision of a hard tooth surface gear is high, the return clearance of a tooth part is small, the bearing capacity is large, the noise is low, and the operation is stable. Output shaft 13 one end sets up two tapered roller bearings 7, and back-to-back installation between two tapered roller bearings 7 can increase bearing capacity, and the output shaft bears the radial force when the moment of torsion still bears the saw bit cutting promptly, cylindrical roller bearing 14 is installed to the output shaft 13 other end, adjusts tapered roller bearing 7 axial clearance through the round nut, can bear big radial force through cylindrical roller bearing 14. The structure can keep the radial runout of the output shaft and the end face runout of the pressure plate position within a reasonable range for a long time. The service life of the whole machine is prolonged. The speed reducer box 2 output shaft center is apart from speed reducer box outside side distance little, effectively improves saw bit 12 utilization ratio, even 12 external diameter wearing and tearing of saw bit also can use after reducing, increase saw bit 12 life, effectively reduce 12 consumptive material costs of saw bit, output shaft 13 is connected with interior pressure disk 8 parallel key, interior pressure disk 8 presss from both sides tight saw bit 12 with outer pressure disk 9 to fasten through lock nut 10, can guarantee beating of saw bit at reasonable within range, extension saw bit live time. The pin holes of the three parts of the inner pressure plate 8, the outer pressure plate 9 and the saw blade 12 are matched with the pin 11 at the same time. The torque output by the speed reducer is transmitted to the saw blade through the pin 11, and cutting force is generated. But also plays a positioning role. The input flange motor flange 1 of speed reducer is according to the motor interface size adaptation of difference, and the form is diversified. The speed reducer special for sawing can be well applied to the industries of aluminum profile, steel structure, metallurgy, high-frequency welded pipe cutting and the like.
