Description
Technical field
The utility model relates to elevator technology fields, and in particular to a kind of permanent-magnet synchnorous gearless dragging machine of thin type.
Background technique
The permanent-magnet synchnorous gearless dragging machine of conventional flat structure, the fixed part of encoder are generally mounted to encoder seat
On, encoder seat is then mounted on the side on engine base of traction machine far from traction sheave, i.e. traction machine rear portion.The rotating part of encoder
It is co-axially mounted with traction machine main shaft.In some situations, encoder is mounted on host rear portion, and encoder replacement can be made to become non-
Often trouble.For example, traction machine of elevator without engine room is mounted in elevator shaft, and between traction machine rear portion and elevator well channel wall
Space very little when, if encoder is mounted on traction machine rear portion, alternate coding device when, need to remove entire host from rack
Come；Alternatively, punching the wall of well that traction machine rear portion is faced outside elevator shaft, can just alternate coding device.
Therefore, in these use occasions, some mechanisms, which are proposed, is mounted on front end for encoder, i.e. encoder is mounted on
The scheme of traction sheave side.For example, Authorization Notice No. is 206,955,416 206126535 U and CN of U, CN of CN
Scheme proposed in 201494993 U patents.The preposition mounting structure of the encoder proposed in these patents, to sum up,
Its principle is all to increase by one in traditional flat structure permanent-magnet synchnorous gearless dragging machine front to fix for installing encoder
Partial bracket, is connected between bracket and base with fastener.There is also disadvantages for this structure.In the permanent magnetism of conventional flat structure
In synchnorous gearless dragging machine, the fore bearing room for installing fore bearing is stretched out from base vertical wall, and it is perpendicular to be located remotely from base
The side of straight wall.And it is mounted on the main load bearing that the fore bearing in fore bearing room is traction machine radial load.Therefore, it is draging
On running wheel when carry radial load, fore bearing room can generate biggish deformation along the vertical direction.Simultaneously as installing
The bracket of encoder is fixed on the outer wall of base traction sheave side, and the deformation of vertical direction can be much smaller than fore bearing room
Deformation.And the stator of encoder is mounted on bracket, but encoder rotor is to be co-axially mounted with fore bearing.Therefore, it encodes
Device stator and rotor axis can generate dislocation with this deformation.This dislocation can operation stability to encoder, reliability and
Service life has adverse effect on.
Summary of the invention
Therefore, the utility model aim be the provision of a kind of encoder be easy installation, that traction sheave is located at base is vertical
The permanent-magnet synchnorous gearless dragging machine of wall side.
What the purpose of this utility model was realized in.
A kind of permanent-magnet synchnorous gearless dragging machine, including base, stator seat, stator, rotor, main shaft, traction sheave, pedestal,
Integrated or separately structure, main shaft both ends pass through bearing respectively and are erected on base and stator seat the main shaft with rotor, traction sheave
Rotor rear face and traction sheave setting are located in base front side, base wraps up traction sheave, and base is equipped with rope through.
It further include encoder, encoder includes fixed part and rotating part, and the fixed part of encoder is mounted on base
On, the rotating part of encoder is mounted on main shaft.
The above technical solution can be further improved as follows.
Base front has muscle to connect base and pedestal.
The traction sheave outermost wire casing projection line is than installing the bearing at main shaft both ends closer to base.
The base is equipped with encoder cover, and the fixed part of encoder is located in encoder cover.
The utility model axial dimension is small, and bearing capacity is strong, reliable for operation, high-efficient, and noise is low, and encoder is easy to install
And replacement.
Detailed description of the invention
Fig. 1 is the present embodiment base appearance diagram.
Fig. 2 is 1 structural schematic diagram of embodiment.
Fig. 3 is 2 structural schematic diagram of embodiment.
Fig. 4 is 3 structural schematic diagram of embodiment.
Specific embodiment
With reference to the accompanying drawing, the utility model is described in further detail.

3, rotor 7, main shaft 11, traction sheave 5, encoder 12, pedestal 14, base front have muscle to connect base and pedestal.The master
Axis 11 and 7 integral structure of rotor, 11 both ends of main shaft pass through bearing 10,8 respectively and are erected on base 1 and stator seat 2, rotor 7
The back side and 5 integral structure of traction sheave, the setting of traction sheave 5 are wrapped up traction sheave 5, are set on base 1 in the positive side of base 1, base 1
There are rope through 1A, 1B, 1C, 1D, the rope on traction sheave 5 can pass through these rope throughs.
Encoder 12 includes fixed part and rotating part, and the fixed part of encoder is mounted on base, encoder
Rotating part is mounted on main shaft.
16 projection line of traction sheave outermost wire casing is than installing the bearing 10,8 at main shaft both ends closer to base 1.
Embodiment 2, in conjunction with Fig. 3, embodiment 2 is only that with the difference of embodiment 1: base 1 is equipped with encoder cover 15, encoder
12 fixed part is located in encoder cover 15.
Embodiment 3, in conjunction with Fig. 4, the difference of embodiment 3 and embodiment 1 is: traction sheave 5 and rotor 7 is split type but it
Be fixed together by screw, rotor 7 may be made as that seperated but they are still fixed together and to be formed with main shaft 11
One entirety.
