Abstract
An output shaft linking device for an internal shaft type electric motor comprises an installing flange 3 which is characterized in that an extraction groove 4 and a combining spigot 5 of a working machine are arranged on the installing flange and an internal shaft 6 of a rotor which is characterized in that an inner hole 7 which is vertical with a shaft end and is coincided with an axis is arranged on the internal shaft of the rotator. The utility model has reasonable design, and outputs power via the interference fit of the inner hole on the internal shaft and an external shaft of the working machine, therefore has convenient installation, and ensures the coaxiality and effectively improves the running reliability.
Description
The utility model relates to a kind of output shaft coupling arrangement of internal-axis type motor, belongs to the motor manufacturing technology field.
General motor all has output shaft, during outputting power, adorns shaft coupling or gear or belt pulley usually to drag various mechanical devices on output shaft.Adopt traditional power way of output, because its axiality is difficult for guaranteeing that it is not steady that mechanical device is moved, and have problems such as energy loss is big, mounting structure is complicated, noise is big, reduction in useful life, operating environment difference.
The purpose of this utility model provides a kind of reasonable in design, compact conformation, can effectively improve the output shaft coupling arrangement of the internal-axis type motor of operational reliability.
The utility model is an internal-axis type motor output shaft coupling arrangement, comprise axle in mounting flange and the rotor, it is characterized in that offering on the described mounting flange cooperation seam of working machine, rise and pull out groove and in rotor, offer endoporus on the axle that endoporus and working crankshaft are interference fit.
The utility model comes outputting power by the endoporus on the axle in the rotor and the interference fit of working machine outer shaft, has improved axiality effectively, operates steadily, and noise is low, and energy consumption is low, has reduced the working machine volume, has improved the life-span of motor and working machine, and easy to assembly.
Accompanying drawing has provided structural representation of the present utility model;
Fig. 1 is the electric machine structure view of prior art;
Fig. 2 is an electric machine structure cutaway view of the present utility model.
Among Fig. 1,1 is armature spindle, and 2 is end cap.
Among Fig. 2,3 is mounting flange, and 4 has been to pull out groove, and 5 for working machine cooperates seam, and 6 is axle in the rotor, and 7 is endoporus.
Below in conjunction with embodiment the utility model is further described:
The utility model mainly pulls out in the rotor that groove 4, working machine cooperate the mounting flange 3 of seam 5 and band endoporus 7 axle 6 etc. and constitutes by taking up.Endoporus in working machine outer shaft and the rotor on the axle 6 cooperates and is interference fit, has guaranteed the axiality of axle and working machine outer shaft axle center in the rotor, has reached the purpose of efficient transfer power.Need be when working machine be pulled down motor, pull out groove 4 and be used with rising by handling instrument, can conveniently rise and pull out motor.
Claims (3)
1. the output shaft coupling arrangement of an internal-axis type motor comprises mounting flange (3), it is characterized in that described mounting flange has been provided with to pull out groove (4) and working machine and cooperate seam (5); Axle (6) in the rotor, it is characterized in that axle in the described rotor be provided with vertical with axial end and with the endoporus (7) of dead in line.
2. press the output shaft coupling arrangement of claims 1 described internal-axis type motor, it is characterized in that axle axis hole (7) is an interference fit with the working machine outer shaft in the described rotor.
