Background

The permanent magnet electric roller is widely applied to various fields such as machine tool industry, textile industry, elevator industry and belt conveyor driving special occasions requiring low speed and large torque due to the excellent electric performance of the permanent magnet electric roller.

In the design of the magnetic pole structure of the permanent magnet electric roller, the permanent magnet is fixed on the inner surface of the rotor and directly faces the air gap, so the fixing mode is always an important problem worthy of discussion; in the past, a magnetic pole structure is usually adhered by special glue, or not only is the magnetic pole structure adhered by the glue but also protective measures are taken on the surface of a permanent magnet, or an axial pressing strip is fixed in a magnetic pole gap. The above measures are prone to the following problems: 1. the special glue is expensive, has more working procedures, needs longer time and can not be judged in the firmness degree; 2. the fixed mode that adopts interelectrode layering needs to bore a large amount of screw holes on the rotor surface, because the rotor directly drives the load, this kind of mode can lead to the fact destruction to rotor intensity, and under certain special situation, permanent magnet motor's permanent magnet has damage or demagnetization phenomenon, in case this phenomenon takes place, hardly takes off the change, and the mode of layering installation can lead to the fact harmful effects to intensity through loosening the screw repeatedly.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a permanent magnetism motorized pulley magnet steel fixed knot constructs to the special glue that provides among the above-mentioned background art of solution is expensive, and the process is more moreover, and the required time is longer, and firm degree can't be judged, and the fixed mode that adopts interelectrode layering needs to bore the problem of a large amount of screw holes on the rotor surface.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a permanent magnet motorized pulley magnet steel fixed knot constructs, includes the rotor urceolus, the rotor urceolus radially has a plurality of permanent magnet at its inner wall evenly distributed, and per two are adjacent install first clamping ring through assembly fixture axial between the permanent magnet, the inside one end of rotor urceolus has the second clamping ring through second positioning bolt fixed mounting, the both ends of rotor urceolus all have the end cover through first positioning bolt fixed mounting.

As a preferred technical scheme of the utility model, a plurality of corresponding first locating holes, two corresponding are all seted up on the surface of the one end of rotor urceolus and end cover first locating hole is all through a positioning bolt fixed connection.

As a preferred technical scheme of the utility model, a plurality of corresponding second locating holes, two corresponding are all seted up to the surface of second clamping ring and the surface of rotor urceolus the second locating hole all is through second positioning bolt fixed connection.

As a preferred technical scheme of the utility model, the other end of rotor urceolus inside is fixed and is equipped with the location step.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model relates to a permanent magnet motorized pulley magnet steel fixed knot constructs, it makes the magnetic pole fix simply fast through first clamping ring and the second clamping ring that sets up, and the second clamping ring passes through second positioning bolt and rotor urceolus fixed connection moreover, is convenient for dismantle for be convenient for change the permanent magnet; meanwhile, the shape optimization design of the permanent magnet can be realized, the material is saved, and the cost is reduced.
