Abstract
The present invention relates to a three-point type permanent magnetic synchronous tractor set without gears, which belongs to the technical field of lifts. The tractor set is formed by the way that two bases which are contiguously connected and used for supporting, mounting and adjusting a concave-convex cambered surface or a facet of a tractor are arranged at the bottom of a permanent magnetic synchronous motor. One end of a rotating shaft of a towing wheel, which is far form the motor is provided with a supporting column, the towing wheel is arranged and racked between a motor rotating shaft and the supporting column of the tractor through an over-long rotating shaft in a bridge way, and the whole tractor has the three-point stress bridge type mounting structure which is formed from two bases which are contiguously connected and arranged at the bottom of the motor and the supporting column. The present invention has the advantages of simple structure, easy production and manufacture, low cost and convenient installation and regulation. Besides, the present invention fundamentally solves the cantilever type stress condition of the motor rotating shaft and the rotating shaft of the towing wheel and avoids the host vibration caused by the deformation because of the nonuniform stress of a lift rotating shaft and the rotating shaft of the towing wheel when the tractor works so as to enhance the running quality of the lift and prolong the service life of the tractor of the lift, and the present invention has favorable popularization and application value and market perspective.
Description
Technical field
The present invention relates to the structure of the structure, particularly slim permanent-magnet synchnorous gearless dragging machine of the towing machine that a kind of elevator drive system uses, belong to the elevator technology field.
Background technology
Existing permanent-magnet synchnorous gearless dragging machine is made up of permagnetic synchronous motor, traction sheave etc., and traction sheave is installed by rotating shaft and is connected the permanent-magnetic synchronous motor rotor end, is cantilevered.Permagnetic synchronous motor is installed on the carriage, is plane contact between motor and the carriage, exists to install to adjust difficulty, is difficult to guarantee setting accuracy.Traction groove on the traction sheave is few and big, is generally five roads or six roads, and driving efficiency is low, and steel cable weares and teares easily.The elevator operation, when traction sheave was stressed, rotor axis of electric, machine shaft were subjected to a moment of torsion, made rotating shaft and shell produce certain distortion easily, also were easy to generate vibrations and low frequency noise, comprising the premature wear of motor bearings.Again because most of permanent-magnet synchnorous gearless dragging machines become flat thin shape, need support of design to carry on the back and haul towing machine, and the planeness of the support of towing machine and squareness requirement all are very high, it is improper to be easy to because of installing, cause the elevator drive system vibrations serious, noise is big, and the overall operation performance descends.
Summary of the invention
Purpose of the present invention is exactly to carry out the revolution of essence to the deficiency that existing cantilevered permanent-magnet synchnorous gearless dragging machine exists, and a kind of three-point permanent magnetic synchronous non-gearing tractor group that is easy to install adjustment is provided.
Realize the technical scheme of the object of the invention: the three-point permanent magnetic synchronous non-gearing tractor group, the traction sheave that comprises the rotating shaft of permagnetic synchronous motor and permanent-magnetic synchronous motor rotor axle head installation bonded assembly band, it is characterized in that being provided with two concavo-convex cambered surface contacts that are used to support with the adjustment towing machine is installed in the permagnetic synchronous motor bottom is connected base, the traction sheave rotating shaft is provided with a pillar stiffener away from an end of motor, and traction sheave is installed by the overlength rotating shaft and striden frame between the machine shaft and pillar stiffener of towing machine.Described concavo-convex cambered surface contact connects base and comprises by the fixing seat of honour of bolted connection and following, the seat of honour with following on be respectively equipped with mutual coupling concavo-convex contact be connected cambered surface.Concavo-convex cambered surface is that spherical contact connects cambered surface.Concavo-convex cambered surface is that the flute profile contact connects cambered surface.The seat of honour and permagnetic synchronous motor shell that contact connects base are welded to connect.Captive joint with carriage for following of cambered surface contact connection base.Described traction sheave is provided with semicircle little and many traction groove.Described pillar stiffener is by comprising that hold-down arm, bearing seat, biserial roller tilting bearing constitute, hold-down arm upper end installation shaft bearing and biserial roller tilting bearing.
Also can be used to support and install the area of adjustment towing machine less than 60cm by be provided with two in the permagnetic synchronous motor bottom
2Facet contact connect base, the traction sheave rotating shaft is provided with one by the pillar stiffener that comprises that hold-down arm, bearing seat, biserial roller tilting bearing constitute away from an end of motor, traction sheave is installed by the overlength rotating shaft and is striden frame between the machine shaft and pillar stiffener of towing machine, realizes being easy to install the three-point permanent magnetic synchronous non-gearing tractor group of adjustment.
The present invention is simple and reasonable, manufactures easily, and cost is low, and is easy for installation.Establish two concavo-convex cambered surface (or facet) contacts that are used to support in the permagnetic synchronous motor bottom and be connected base, formed two stress points in " 3 points " that supports towing machine like this with the adjustment towing machine is installed; Be provided with the pillar stiffener that comprises that hold-down arm, bearing seat, biserial roller tilting bearing constitute, traction sheave is installed by the overlength rotating shaft and is striden frame between the machine shaft and pillar stiffener of towing machine, formed sedan-chair formula mounting structure, pillar stiffener is another the main stress point that supports in " 3 points " of towing machine.The permagnetic synchronous motor bottom is established two concavo-convex cambered surface (or facet) contacts that are used to support with the adjustment towing machine is installed and is connected base, is convenient to the installation adjustment of towing machine, improves setting accuracy.Traction sheave is installed and is striden frame between the machine shaft and pillar stiffener of towing machine, former cause towing machine is carried elevator weight separately to be made into to be carried jointly by motor two point and pillar stiffener single-point, alleviated the bearing capacity of rotor 50%, thereby the motor that makes towing machine rotates operation easily, has avoided the generation of low frequency electromagnetic noise.Little and many semicircle traction groove is set on the traction sheave, and through-put power is big, and the driving efficiency height reduces the damage of belt.Technical scheme of the present invention has fundamentally solved the cantilevered force-bearing situation of machine shaft, traction sheave rotating shaft, when avoiding towing machine work, and elevator rotating shaft, traction sheave rotating shaft unbalance stress and be out of shape and cause the main frame vibrations.Improve the elevator running quality, prolong the service life of the towing machine of elevator, improved the machine shaft overload capacity and reached more than 90%, excellent popularization using value and market outlook are arranged.
