Description
Technical field
the utility model relates to a kind of traction machine, particularly a kind of permanent-magnet synchronous external rotor traction machine.
Background technology
traction machine is the power-equipment of elevator, also known as elevator main.Function is that conveying makes elevator run with transferring power.And permanent-magnet synchronous external rotor traction machine is a kind of traction machine comparatively commonly used.And outer rotor tractor, as the term suggests be exactly the traction machine that rotor is positioned at outside electronics.At present, most of permanent-magnet synchronous external rotor traction machine is all generally the structure adopting deep-groove ball roller bearing, and this structure is subject to great limitation in load.
Utility model content
the purpose of this utility model is, provides a kind of permanent-magnet synchronous external rotor traction machine.Its structure can make traction machine have larger load, and assembles convenient.
the technical solution of the utility model: permanent-magnet synchronous external rotor traction machine, is characterized in: comprise the stator winding on support and support, be provided with rotating shaft in support, rotating shaft is arranged in support by two taper roll bearings; Described rotating shaft side is provided with flange, and opposite side is provided with two round nuts, and two taper roll bearings are between flange and round nut; Described flange is fixed with external rotor, external rotor is fixed with traction sheave.
in above-mentioned permanent-magnet synchronous external rotor traction machine, the both sides of described taper roll bearing are equipped with sealing ring.
in aforesaid permanent-magnet synchronous external rotor traction machine, described external rotor is fixed by screws on the flange of rotating shaft, and described flange and rotating shaft are structure as a whole.
compared with prior art, the utility model coordinates special assembly structure by using taper roll bearing, traction machine of the present utility model can be made to bear larger load, and assemble more convenient.In addition, the utility model can regulate the pretightning force of bearing by round nut.
Accompanying drawing explanation
fig. 1 is structural representation of the present utility model.
being labeled as in accompanying drawing: 1-stator winding, 2-external rotor, 3-support, 4-round nut, 5-taper roll bearing, 6-rotating shaft, 7-sealing ring, 8-flange, 9-traction sheave.
Embodiment
below in conjunction with drawings and Examples, the utility model is further described, but not as the foundation limited the utility model.
embodiment.Permanent-magnet synchronous external rotor traction machine, as shown in Figure 1: comprise the stator winding 1 on support 3 and support 3, be provided with rotating shaft 6 in support 3, rotating shaft 6 is arranged in support 3 by two taper roll bearings 5; Described rotating shaft 6 side is provided with flange 8, and opposite side is provided with two round nuts, 4, two taper roll bearings 5 between flange 8 and round nut 4; Described flange 8 is fixed with external rotor 2, external rotor 2 is fixed with traction sheave 9.The both sides of described taper roll bearing 5 are equipped with sealing ring 7.Described external rotor 2 is fixed by screws on the flange 8 of rotating shaft 6.Described flange 8 is structure as a whole with rotating shaft 6.
the utility model is when assembling, and the utility model can pass through adjustment two round nuts, and the pretightning force of bearing is adjusted to optimum position.
