Description
Technical field
The present invention relates to electric machine structure, particularly large high-speed electromotor whole structure.
Background technology
Along with fast development of national economy, industries such as electric power, machinery are also more and more higher to the requirement of motor.From motor install and use environment analysis, conventional mounting can not satisfy various operating modes in indoor motor, as the instructions for use under the situations such as open-air fully or koniology is very big.
Require to be the outdoor motor of occasion in the open that traditional degree of protection is that the motor that IP44 requires can not meet the demands, but will adopt the asynchronous motor of degree of protection IP55 for environment for use.Because the rotating speed very high (3000 rev/mins of synchronous speeds) of two-pole machine, the problems of bringing to motor such as vibrations are key factors of puzzlement high-speed asynchronous motor development always thereupon.Traditionally in order to solve the vibration problems of high-speed electric expreess locomotive, what adopt usually is the mounting structure (IM7211) of pedestal bearing, on the stressed base that acts directly on motor that it brings rotor to bearing, thereby alleviated the stressed of electric machine stand greatly, near and reduced the vibrations of motor.But this motor is because bearing has a segment distance between support, thereby armature spindle makes its degree of protection lower among can not being closed in support fully, generally can only be used for indoor environment and use.
In addition, because two-pole machine rotating speed height, the weldering muscle axle that adopts is difficult to satisfy the critical whirling speed of motor and the requirement of centrifugal force usually.
Summary of the invention
The object of the invention is to provide a kind of employing novel mounting structure, improves degree of protection, is suitable for the large high-speed electromotor whole structure of outdoor use.
The technical scheme that technical solution problem of the present invention is taked is: a kind of large high-speed electromotor whole structure, motor comprise support, end cap, stator, axle, rotor and bearing, wherein:
Described support is a case structure, is " birdcage " structure, is equipped with two or more reinforcement up and down on four side plates, and the support two ends fixedly wall of end cap process with the thick 40mm of full circle ± 3 steel plates;
Thick 50mm ± directly process one-body molded by 3 steel plates with full circle for described end cap, contact-making surface is bright and clean between end cap and support and bearing, closely contact seal mutually, end cap and support, the coupling part of end cap and bearing all guarantees fineness, guarantee that then the contact-making surface between end cap and support and bearing reaches seal request, the degree of protection that adopts the end cap of this kind structure not only to help motor requires but also has improved the rigidity of whole end cap, also help reduce high-speed electric expreess locomotive operation be easy to generate vibrations may;
Described stator, its stator core is fixing with the full circle steel plate welding of three thick 20mm ± 3, stator core is by interior press-loading process moulding, improve support and born the ability of moment of torsion and the stress requirement of itself, therefore out frame adopts case structure, and is all very favourable to the rigidity, the globality that increase support and the vibrations that reduce motor.
Axle processes by hot cover process with rotor core, with the critical whirling speed that satisfies motor and the requirement of centrifugal force;
Bearing is end bracket type bearing, has the twice floating seal ring, and the outside is provided with outer cover.
On the such scheme basis, the interior press-loading process moulding of described employing stator core, also to cause support in the end may produce the process of micro-strain in the welding process after the press-loading process process has avoided outer press mounting structure stator built-in line to finish in this, comprise the steps: with the last welding of support
The first step: the support welding processing is proofreaied and correct;
Second step: directly be pressed into stator punching;
The 3rd step: rule;
The 4th step: stator core and support be the VPI dipping lacquer in the lump.
The two ends of described axle are separately installed with centrifugal fan.Guarantee air quantity and wind speed that motor internal is required, guaranteed the unimpeded of wind path.
Be equipped with through hole on the end cap of described bearing and the motor fan shroud, and connect by pipeline.Because motor speed height, bearing and easy the generation are got rid of oily phenomenon, now be introduced directly in the bearing chamber, increase the air pressure in the bearing by the zone of positive pressure of fan with the motor internal wind path, this to reducing since the too high generation lubricating oil of motor speed to climb oil to motor internal vertically very favourable.
The invention has the beneficial effects as follows:
1, the present invention has adopted the mounting structure of IMB3, carries out vibrations and all electric properties that optimal design makes motor from structure and meets design requirement fully, can satisfy the instructions for use under the operating modes such as open-air or koniology is very big;
2, changed the installation form that traditional high-speed electric expreess locomotive adopts pedestal bearing, stressed all the acting on bearing and the end cap that support is connected that rotor is brought to bearing, thus make degree of protection reach the requirement of IP55.
3, contact-making surface is bright and clean between end cap and support and bearing, and closely contact reaches seal request mutually, and the degree of protection that helps motor requires and improved the rigidity of whole end cap, also helps to reduce high-speed electric expreess locomotive is easy to generate vibrations in operation possibility.
4, support adopts the case structure of " birdcage ", increases rigidity, the globality of support, reduces the vibrations of motor;
5, adopt hot cover process, satisfied the critical whirling speed of motor and the requirement of centrifugal force;
6, also to cause support in the end may produce micro-strain in the welding process after interior press-loading process moulding has avoided outer press mounting structure stator built-in line to finish with the last welding of support.
7, the centrifugal fan of the two ends of axle setting has guaranteed air quantity and the wind speed that motor internal is required, has guaranteed the unimpeded of wind path;
8, be introduced directly in the bearing chamber by the zone of positive pressure of fan, increase the air pressure in the bearing, reduced because the too high generation lubricating oil of motor speed is climbed the situation of oil vertically to motor internal with the motor internal wind path.
