Description

Technical Field

[0001] The utility model relates to the technical field of reducers, in particular to a reducer frequency converter. Background Art

[0002] A reducer is a mechanical transmission device whose main function is to reduce the speed and increase the torque. It is widely used in various occasions where the speed needs to be reduced, such as cranes, conveyor belts, etc.; the frequency converter converts the industrial frequency power supply into an electric energy control device of another frequency through the on-off action of power semiconductor devices to achieve variable speed operation of the motor.

[0003] The transmission components of existing reducers mostly use spur gears, which can only bear radial loads but not axial loads. This will lead to unreasonable load distribution, thereby shortening the overall life of the gearbox. In addition, the spur gears have low bearing capacity and are at risk of tooth breakage when facing large bearing forces. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, one of the purposes of the utility model is to provide a speed reducer inverter, which realizes low-power and high-torque output force by setting a first-stage gear assembly, a second-stage gear assembly, a third-stage gear assembly, and an output assembly, and the spiral assemblies are meshed with each other, and no gear will deviate during the rotation of the machine. Compared with straight teeth, the rotational torque of helical teeth is higher than that of straight teeth, and it has an advantage in bearing axial loads. Since the tooth surface contact line of the helical gear is oblique, the gear teeth gradually enter into meshing and gradually disengage from meshing, reducing the impact and noise during loading and unloading, and improving the smoothness of the transmission.

[0006] The side wall of the helical gear shaft 1 is meshed and connected with the side wall of the helical gear 2, the side wall of the helical gear shaft 2 is meshed and connected with the side wall of the helical gear 3, and the side wall of the helical gear shaft 3 is meshed and connected with the side wall of the output helical gear.

[0007] According to the reducer frequency converter, the bottom ends of the helical gear 1, the helical gear 2, the helical gear 3 and the output helical gear are all fixedly connected with a rotating shaft, and the bottom ends of the rotating shafts are all rotatably connected to the top end of the chassis.

[0008] According to the reducer frequency converter, the inclination angles of the helical teeth of the helical gear one, the helical gear two, the helical gear three and the output helical gear become smaller in sequence, and the tooth pitches become larger in sequence.

[0009] A speed reducer frequency converter is provided, wherein the inclination angles of the helical teeth of the helical gear shaft one, the helical gear shaft two and the helical gear shaft three become smaller in sequence, and the tooth pitches become larger in sequence.
