Description
Technical field
This utility model relates to the mounting structure of a kind of elevator traction machine encoder.
Background technology
Traction machine is the power-equipment of elevator, and its function is that conveying makes elevator run with transmission power.In work, motor turns
Dynamic drive traction sheave rotates, and the steel wire rope on traction sheave drags car and counterweight performs relative motion, and makes car along leading in hoistway
The upper and lower reciprocal operation of rail, completes the transport work of elevator.
The encoder such as Heidenhain ERN1387 encoder that elevator traction machine is conventional, its common mounting means such as Fig. 1 institute
Showing, during installation, king-bolt 5 ' sequentially passes through encoder rotor hole 21 ' and horse from support shaft 1 ' left side (non-motor shaft installation side)
Encoder 2 ' rotor is locked by the bolt hole 31 ' reaching spindle central with motor shaft 3 ', then, still left from support shaft 1 '
Side adjusts the stove bolt 6 ' of encoder expansion sleeve 4 ', make expansion sleeve 4 ' swelling in support shaft 1 ' endoporus, thus by encoder 2 '
Housing is fixed in support shaft 1 ' endoporus, completes the installation of encoder.
Above-mentioned mounting means so that encoder loads after elevator traction machine, during the whole service life of elevator in, volume
Therefore traction machine just, can only be used environment to propose spatially from traction machine back side disassembling, assembling and replacing once damage by code device
The necessary distance enough apart from wall of installation of requirement, i.e. traction machine, reserves the space changing dismounting, otherwise, just can only tear open
The replacing of encoder just can be carried out except whole traction machine；Above-mentioned situation constrains traction machine use under less spatial environments,
The especially use on machine-roomless lift.
Summary of the invention
In order to overcome the deficiencies in the prior art, this utility model provides the mounting structure of a kind of elevator traction machine, can realize
Encoder is dismounted in traction machine front end.
This utility model solves its technical problem and be the technical scheme is that
The mounting structure of a kind of elevator traction machine encoder, including the volume arranged in traction machine support shaft and support shaft endoporus
Code device, described encoder has expansion sleeve, and encoder rotor is connected fixing with motor shaft, and described motor shaft center is provided with to be passed through
The bolt hole of logical rotating shaft, has king-bolt to sequentially pass through described motor shaft bolt hole and described encoder is turned by encoder rotor hole
Son is locked with motor shaft, and described support shaft is uncovered at motor shaft installation end, and the diameter of this opening end
Encoder can be taken out from this opening end；The circumference of described encoder expansion sleeve has surface groove, is provided with in surface groove
Wedge block, has stove bolt to penetrate this wedge block from expansion sleeve front end face and makes expansion sleeve swelling incite somebody to action in described support shaft endoporus
Described encoder housing is fixed.
Described motor shaft has the installing hole leading to described stove bolt.
The beneficial effects of the utility model are: elevator traction machine encoder of the present utility model is achieved by structure design
From traction machine front end, encoder is carried out disassembling, assembling and replacing, expanded the mounting means of encoder so that the installation environment of traction machine
It is not limited by a space, the use on machine-roomless lift can be met, be substantially reduced later maintenance replacement cost.
Accompanying drawing explanation
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of prior art；
Fig. 2 is the structural representation of a kind of embodiment of the present utility model；
Fig. 3 is the structural representation of another kind of embodiment of the present utility model.
Detailed description of the invention
With reference to Fig. 2, the mounting structure of a kind of elevator traction machine encoder, including traction machine support shaft 1 and support shaft endoporus
The encoder 2 of middle setting, described encoder 2 has expansion sleeve 4, and encoder 2 rotor is connected fixing with motor shaft 3, described horse
Reach rotating shaft 3 center and be provided with the bolt hole 31 of through rotating shaft, have king-bolt 5 to sequentially pass through described motor shaft bolt hole 31 and coding
Described encoder 2 rotor is locked by device rotor hole 21 with motor shaft 3, and described support shaft 1 at motor shaft installation end is
Uncovered, and the diameter of this opening end 11 makes encoder 2 can take out from this opening end；Described encoder expansion sleeve 4
Circumference have surface groove 41, be provided with wedge block 42 in surface groove 41, have stove bolt 6 to penetrate this from expansion sleeve 4 front end face
Wedge block 42 makes expansion sleeve swelling be fixed by described encoder 2 housing in described support shaft 1 endoporus.
During the installation of above-mentioned elevator traction machine encoder, first encoder 2 is placed in support shaft 1 endoporus, makes encoder
The one end at expansion sleeve 4 place is outwardly；Adjust stove bolt 6 by inner hexagon spanner, make the wedge block in expansion sleeve surface groove 41
42 move, and expansion sleeve 4 swelling is in support shaft 1 endoporus, thus is fixed in support shaft 1 endoporus by encoder 2 housing；Finally,
King-bolt 5 is sequentially passed through bolt hole 31 and the encoder rotor hole 21 of the through rotating shaft at motor shaft center, locks big spiral shell
Bolt 5, so that encoder 2 rotor is locked with motor shaft 3.
With reference to Fig. 3, another embodiment of the present utility model, this embodiment with a upper embodiment difference is: at motor shaft 3
Have the installing hole 7 leading to described stove bolt 6.
During installation, it is with the difference of a upper embodiment, after encoder 2 is placed in support shaft 1 endoporus, needs
First encoder 2 rotor is locked with motor shaft 3, the most again by the inner hexagon spanner installing hole from described motor shaft
7 stretch into and lock near encoder expansion sleeve 4, encoder housing are fixed in support shaft 1 endoporus.
The mounting structure advantage of this embodiment is: before and after placing in supporting shaft hole for encoder, status requirement is not
Height, can disposably complete to install, it is not necessary to repeats to debug the position of encoder, installs more convenient.
Elevator traction machine encoder of the present utility model achieves to enter encoder from traction machine front end by structure design
Row disassembling, assembling and replacing, has expanded the mounting means of encoder so that the installation environment of traction machine is not limited by a space, and can meet inorganic
Use on machine room-free elevator, is substantially reduced later maintenance replacement cost.
