Abstract
The invention discloses a permanent magnet synchronous outer rotor traction machine. The permanent magnet synchronous outer rotor traction machine comprises a base (3) and a stator winding (1) on the base (3). A rotating shaft (6) is arranged in the base (3). The rotating shaft (6) is arranged in the base (3) through two tapered roller bearings (5). A flange (8) is arranged on one side of the rotating shaft (6). Two round nuts (4) are arranged on the other side. The two tapered roller bearings (5) are located between the flange (8) and the round nuts (4). An outer rotor (2) is fixed on the flange (8). A traction sheave (9) is fixed on the outer rotor (8). According to the structure provided by the invention, the traction machine has the advantages of great load and easy assembly.
Description
Technical field
the present invention 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.
Summary of the invention
the object of the invention is to, a kind of permanent-magnet synchronous external rotor traction machine is provided.Its structure can make traction machine have larger load, and assembles convenient.
technical scheme of the present invention: a kind of 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 present invention coordinates special assembly structure by using taper roll bearing, traction machine of the present invention can be made to bear larger load, and assemble more convenient.In addition, the present invention can regulate the pretightning force of bearing by round nut.
Accompanying drawing explanation
fig. 1 is structural representation of the present invention.
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 present invention is further illustrated, but not as the foundation limited the present invention.
embodiment.A kind of 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 present invention is when assembling, and the present invention can pass through adjustment two round nuts, and the pretightning force of bearing is adjusted to optimum position.
