Abstract
Signal-axle-bridge structure gearless traction machine belongs to the elevator technology field. The traction machine is equipped with stand, the traction motor is equipped with super long rotary axle, the overhanging end of the super long rotary axle is installed on the stand, the traction wheel is installed on the super long rotary axle between the traction motor and the stand. The distance between the traction wheel and the traction motor is equal with or more than the distance between the traction wheel and stand. The invention has simple and reasonable structure, the traction wheel installation uses bridge structure, it reduces the bearing capacity of the traction motor, reduces rotary axle bending deformation, vibration generated by unit and rotor bearing abrasion, and increases the loading weight of traction machine, saves costs, extends the use life of traction motor and improves the elevator operation quality. The position of installing traction wheel deviates to the direction of stand, it is farer away the traction motor and is near the stand, it increases the bearing capacity of traction machine, the bearing capacity of traction machine in same volume and format is increased more over 130%.
Description
Technical field
The present invention relates to a kind of structure that designs the single-axle type gearless machine, belong to the field of elevator technology.
Background technology
The gearless machine that present elevator adopts, basically be the pattern of one traction sheave being installed at the end that the rotating shaft of gearless traction motor is stretched out, traction sheave is connected gearless traction motor roller end, be cantilevered, when traction sheave was stressed, the traction motor rotating shaft was subjected to a moment of torsion, rotating shaft is easy to generate flexural deformation, unit produces vibrations, and rotor-bearing weares and teares easily, influences towing machine service life and elevator running quality.Certain restriction is arranged on speed, volume and load carrying ability simultaneously.
Summary of the invention
The objective of the invention is to provide a kind of simple and reasonable single-axle type structure gear-free traction machine.
The object of the present invention is achieved like this, single-axle type structure gear-free traction machine, comprise traction motor, traction sheave, it is characterized in that towing machine is provided with support, described traction motor is provided with the overlength rotating shaft, the external part of overlength rotating shaft is installed and is supported on the support, and traction sheave is installed in the overlength rotating shaft between traction motor and the support.
Described traction sheave to the distance of traction motor that is installed in the overlength rotating shaft is equal to or greater than the distance to support.
The present invention is simple and reasonable, and traction sheave is installed and adopted bridge architecture, reduces the bearing capacity of traction motor, reduce shaft bending distortion, unit generation vibrations and rotor-bearing wearing and tearing, increase the towing machine load carrying ability, save cost, prolong the service life of traction motor, improve the elevator running quality.The position that traction sheave is installed is offset to holder orientation, and is far away apart from traction motor, nearer apart from support.Therefore loading on the support more than 50% born the load below 50% on the traction motor, and the duty ratio of bearing on the big I decision of the out-of-position traction motor generally can be controlled in about 30～40%.Improve the load-carrying capacity of towing machine, the towing machine load carrying ability of equal volume, specification can increase more than 130%.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Among the figure: 1 traction motor, 2 traction sheaves, 3 supports, 4 overlength rotating shafts, 5 carriages, 6 bolts.
The specific embodiment
The rotor shaft of traction motor 1 is designed to overlength rotating shaft 4, and the overlength rotating shaft external part of traction motor 1 is installed on the support 3, and conventional antifriction-bearing box mounting means is adopted in the installation of overlength rotating shaft and support.Traction sheave 2 is installed in the overlength rotating shaft between traction motor 1 and the support 3, traction sheave 2 to the distance of traction motor 1 greater than distance to support 3.Traction motor 1 and support 3 are provided with and are installed on the carriage 5, and traction motor 1 is connected and fixed by bolt 6 and carriage 5.
Claims (2)
1, single-axle type structure gear-free traction machine, comprise traction motor, traction sheave, it is characterized in that towing machine is provided with support, described traction motor is provided with the overlength rotating shaft, the external part of overlength rotating shaft is installed and is supported on the support, and traction sheave is installed in the overlength rotating shaft between traction motor and the support.
2, single-axle type structure gear-free traction machine according to claim 1 is characterized in that being installed in traction sheave to the distance of traction motor in the overlength rotating shaft and is equal to or greater than distance to support.
