Abstract
The utility model discloses a motorized spindle rotor core double-conical-surface locating mechanism. The motorized spindle rotor core double-conical-surface locating mechanism comprises a spindle, a taper sleeve and a rotor core, wherein the rotor core is connected on the spindle in a sleeved mode, a first conical surface is machined on the spindle, the inner side of the rotor core is matched with the first conical surface of the spindle, the taper sleeve is sleeved on the spindle at outer side of the rotor core, the outer surface of the taper sleeve is machined into a second conical surface, the outer side of the rotor core is matched with the second conical surface, the taper sleeve is matched with the spindle through a pillar surface, and the taper sleeve is fixed on a pillar surface structure of the spindle. The spindle and the core adopt double-conical-surface centering structures, and therefore the requirements for the entire structural design can be met, and the motorized spindle rotor core double-conical-surface locating mechanism is high in locating accuracy, good in reliability, simple and convenient to machine, and convenient to install and detach.
Description
Technical field
The utility model relates to a kind of detent mechanism of electric main shaft.
Background technology
Traditional rotor combination is to be integral by iron core and main shaft interference fit, because electric main axle structure is compact, the impact that mutually restricted by the correlated parts size, often need in structural design main shaft and iron core in conjunction with separable form structure.
The utility model content
Compact for solving electric main axle structure, be subjected to the problem of the impact that the correlated parts size restricts mutually, a kind of electric spindle rotor iron core Double-conical-surface detent mechanism of the utility model design.
The purpose of this utility model is come specific implementation by the following technical programs:
Electricity spindle rotor iron core Double-conical-surface detent mechanism, comprise main shaft, tapered sleeve and rotor core, described rotor core is socketed on main shaft, be processed with first conical surface on main shaft, the first cone match of the inboard of described rotor core and main shaft, be socketed with tapered sleeve on the outside main shaft of rotor core, the outer surface of described tapered sleeve is processed into second conical surface, the second cone match of the outside of described rotor core and described tapered sleeve, coordinate by cylinder between described tapered sleeve and main shaft, and described tapered sleeve is fixed on the cylindrical structure of described main shaft.
This structure adopts the Double-conical-surface adjective-centre structure with main shaft and iron core, can satisfy the overall construction design requirement like this, and positioning accuracy is high, good reliability, and processing is simple, mounting or dismounting are convenient.
