The utility model discloses a primary and secondary formula double speed toper rotor three -phase asynchronous motor assists motor shaft right -hand member and quick -witted case clearance fit for the easily disconnected defect of subsidiary motor shaft even motor shaft is assisted down to the overload state passes through the box and obtain interim the support, has been avoided to pinion atress between epaxial two bearing points. The utility model provides an easily the break structural approach of problem of brand -new solution motor shaft, it is respond well through experimental identification, showing and improving the life who assists motor shaft in the primary and secondary two -speed motor.
Description
Technical field
The utility model belongs to a kind of electric rotating machine, relates generally to lifting, machinery, the industries such as building, requires that motor itself has two kinds of speed.
Background technology
Primary and secondary double speed cone rotor threephase asynchronous is by two taper asynchronous motors, is connected by one group of two-stage gear shift, to realize two kinds of friction speeds.What power was larger is main motor, i.e. female motor, another is lower-powered is auxiliary motor, i.e. sub-motor, when female motor energising work, sub-motor no power and be in on-position, only main shaft is driven to run up by female motor, and during the energising of sub-motor, female motor no power and be in on-position, now drives main shaft microrunning by drive unit at a slow speed.During group motor overload, because transmission is monolateral stressed, easily there is off-axis phenomenon.
Utility model content
The purpose of this utility model is the problems referred to above that will solve prior art existence, provides a kind of novel primary-secondary type double speed cone rotor threephase asynchronous.Concrete technical scheme is as follows:
A kind of primary-secondary type double speed cone rotor threephase asynchronous, comprise main motor, auxiliary motor, be combined as a whole by cabinet, it is characterized in that: gear wheel installed by cabinet, auxiliary motor axle installs pinion, and gear wheel is connected by transition gear with pinion; Auxiliary motor axle passes on left bearing and fixes, and right-hand end stretches into cabinet wall and cabinet matched in clearance, and pinion is arranged in the middle part of axle.
Preferably, main motor axle right hand side keys connects braked wheel, and gear wheel is connected by trip bolt with Brake Block, and main motor axle is set with pressure spring, is connected in cabinet and main motor between centers, and under off-position, pressure spring makes braked wheel and Brake Block be close to.
Preferably, auxiliary motor right-hand end and the radial 0.2mm matched in clearance of cabinet.
Preferably, transition gear is arranged on transition gear axle, and transition gear axle is arranged on cabinet.
In order to obtain better motor reel useful life, the mechanical performance that usual employing improves motor reel overcomes the defects such as motor reel is easily broken, primary-secondary type double speed cone rotor threephase asynchronous of the present utility model, auxiliary motor axle right-hand member and cabinet matched in clearance, make pinion stressed between two supporting points on axle, even if auxiliary motor axle obtains temporary support by casing under overload, avoid the defect that auxiliary motor axle is easily broken.Provide a kind of structural approach of the easily broken problem of solution motor reel completely newly, prove through overtesting, respond well, significantly improve the useful life of auxiliary motor axle in primary and secondary two-speed motor.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1-main motor, 2-auxiliary motor, 3-cabinet, 4-pinion, 5-auxiliary motor axle, 6-transition gear, 7-transition gear axle, 8-braked wheel, 9-gear wheel, 10-Brake Block, 11-main motor axle, 12-trip bolt, 13-pressure spring.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further details.
As shown in the figure, a kind of primary-secondary type double speed cone rotor threephase asynchronous, comprises main motor 1, auxiliary motor 2, be combined as a whole by cabinet 3, cabinet 3 is installed gear wheel 9, auxiliary motor axle 5 is installed pinion 4, gear wheel 9 is connected by transition gear 6 with pinion 4; Auxiliary motor axle 5 passes on left bearing and fixes, and right-hand end stretches into cabinet wall and cabinet 3 matched in clearance, auxiliary motor 2 right-hand end and the radial 0.2mm matched in clearance of cabinet 3, and pinion 4 is arranged in the middle part of axle; Main motor axle 11 right hand side keys connects braked wheel 8, gear wheel 9 is connected by trip bolt 12 with Brake Block 10, main motor axle 11 is set with pressure spring 13, is connected between cabinet 3 and main motor axle 11, under off-position, pressure spring 13 makes braked wheel 8 and Brake Block 10 be close to.Transition gear 6 is arranged on transition gear axle 7, and transition gear axle 7 is arranged on cabinet 3.
When main motor 1 is energized, during auxiliary motor 2 no power, main motor axle 11 is under the effect of axial magnetic, compression pressure spring 13 left, drive braked wheel 8 to be moved to the left, braked wheel 8 is separated with Brake Block 10, and main motor axle 11 is high speed rotating under the effect of radial magnetic force simultaneously.
When main motor 1 no power, when auxiliary motor 2 is energized, auxiliary motor axle 5 drivening piece pinion 4, pinion 4 transmits torque on gear wheel 9 by transition gear 6, gear wheel 9 is tightened to one with Brake Block 10 by trip bolt 12, braked wheel 8 is connected by spline with main motor axle 11, under the reaction force acts of pressure spring 13, braked wheel 8 and Brake Block 10 tightly press together, when auxiliary motor 2 operates, when moment is delivered to Brake Block 10, Brake Block 10 relies on frictional force band brake to take turns 8 and rotates, main motor axle 11 also rotates thereupon, due to the speed ratio factor of gear, main motor axle 11 slow rotation, thus make whole mechanism have primary and secondary two kinds of fast low-rotate speeds.
