Abstract

The utility model relates to the technical field of mechanical drive device, in particular to a sleeve-type electrical spindle. The sleeve-type electrical spindle comprises a casing, a stator, a rotor, a spindle and a rotor bushing, wherein the spindle is inserted into the casing; the stator is mounted on the casing; the rotor is connected with the spindle through the rotor bushing; the middle part of the spindle is a quadrangular prism body; and the rotor bushing is a barrel body. Based on sleeve connection between the spindle and the rotor bushing through the quadrangular prism body at the middle part of the spindle, the sleeve-type electrical spindle provided by the utility model is simple in structure, convenient in assembly and disassembly, and improved in assembly effect, and can be prevented from being damaged during assembly and disassembly, and the manufacture and use costs can be lowered.

Description

Socket joint type electricity main shaft

Technical field

The utility model relates to the mechanical driving device technical field, especially a kind of socket joint type electricity main shaft.

Background technology

At present, in electric principal shaft product series, the rotor of main motor directly is solidly set on the main shaft, main shaft is motor shaft, and transmission efficiency is high, and dynamic response is fast, omitted a whole set of mechanical driving device, compact conformation, still, rotor is to be connected by screw to be fixed on the main shaft, and when needs dismounting main shaft keeped in repair, the main shaft dismounting will sustain damage, simultaneously, because interference fit can not be changed bearing, after the damage of bearings of main shaft, main shaft just can only do to scrap processing.

The utility model content

Inconvenient in order to overcome existing electric spindle rotor dismounting, the deficiency that production cost is high, the utility model provides a kind of socket joint type electricity main shaft.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of socket joint type electricity main shaft, comprise housing, stator, rotor, main shaft and rotor cover, main shaft is inserted in the housing, stator is installed on the housing, rotor is connected on the main shaft by the rotor cover, the main shaft middle part is four-prism, and the rotor cover is cylindrical shell.

According to another embodiment of the present utility model, comprise that further the two ends of main shaft are provided with nut.

According to another embodiment of the present utility model, comprise that further the rotor cover is enclosed within on the main shaft, be clipped between two nuts.

The beneficial effects of the utility model are; the main shaft middle part is four-prism, and the rotor cover is cylindrical shell, and both fits connect; directly define radial displacement between the two; the two ends of rotor cover arrange nut, limit axial displacement, and are simple in structure; assembly and disassembly are convenient; improve the effect of spindle mounted, protected simultaneously main shaft in assembling and unloading process, not sustain damage, reduced manufacturing cost and use cost.
