Description
Technical field
The utility model belongs to technical field of motors, is specifically related to a kind of main shaft structure, particularly a kind of main shaft structure of frequency conversion braking motor.
Background technique
Motor is one of requisite accessory in crane gear, in hoist work, need the continuous work of motor to provide power, during main shaft, motor outwards provides the critical piece of torsion, usual motor provides kinetic energy by electric energy conversion to the main body of main shaft, and the transmission of torsion is externally carried out by main shaft, come out from the distribution of moment of torsion, the average torsion that main shaft bears in the part of motor internal is less, and it is larger to stretch out the torsion that motor part bears, and when main axis stiffness requires that major axis diameter is unsuitable too small, how to reduce energy consumption and consumptive material and become the problem needing to solve, therefore, provide a kind of rational in infrastructure, efficiency is high, the main shaft structure of long service life, good in economic efficiency frequency conversion braking motor is necessary.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and provide a kind of rational in infrastructure, efficiency is high, the main shaft structure of long service life, good in economic efficiency frequency conversion braking motor.
The purpose of this utility model is achieved in that a kind of main shaft structure of frequency conversion braking motor, it comprises main body, the left part of described main body is provided with bearing A, the right side of described bearing A is provided with splined shaft, and the right side of described splined shaft is provided with the shaft shoulder, and described shaft shoulder arranged outside has keyway, described main body right part is provided with bearing B, inside described main body left part, porose A is set, inside described main body right part, porose B is set, on the downside of described hole B left end, be provided with circular hole.
Described bearing A and bearing B is deep groove ball bearing.
Described keyway is semicircle keyway.
Described hole A is cylindrical hole.
Described hole B is cylindrical hole.
The beneficial effects of the utility model: the utility model adopts splined shaft, when mounted, can load onto flying wheel at splined shaft place, can be improved the efficiency utilization ratio of motor, reach energy-saving and cost-reducing effect by the effect of flying wheel; The utility model adopts hole A and hole B, both saves consumptive material, and alleviates the quality of main shaft, and also make the radiating effect of main shaft better, reasonable integral structure, while reducing manufacture cost, improves the working efficiency of motor; The utility model has that structure is reasonable, efficiency is high, long service life, good in economic efficiency advantage.
