Description
Technical field
The utility model relates to traction electric machine technical field, specifically a kind of lightweight high-intensity electric machine stand.
Background technology
The traction motor used on high-speed railway at present, mostly be Welding Structure, thickness is thicker, and density is large, and structure is simple, and ventilation effect is general.Another part adopts spheroidal graphite cast-iron support, and inwall is relatively thick, improper ventilation, is unfavorable for the lightweight of motor.Pursuit support wall as is simply thin, and while alleviating motor weight, the mechanical strength of support can reduce gradually.
Along with the modernization of the railway system and the rapid raising of automatization level, the prolongation of the lightweight of motor-car vehicle, high speed and route, plays important facilitation to the fast development of national economy undoubtedly.Improving electric machine stand structural strength and mounting means, reduce the quality of support, is the direction of this area research design.
Summary of the invention
The purpose of this utility model has that inwall is thicker, heavier-weight, support intensity are poor and the problem such as ventilation effect is bad to solve existing traction motor, and provide a kind of lightweight high-intensity electric machine stand.
The utility model is achieved by the following technical solution:
A kind of lightweight high-intensity electric machine stand, comprise machine base body, machine base body offers the support inner chamber of through machine base body, the chamber wall of support inner chamber is evenly equipped with some interior muscle along the direction of support inner chamber axis, interior muscle is provided with the boss of epirelief near the end of exit end, the position near import on the chamber wall of support inner chamber is provided with a ring muscle; The side sidewall of machine base body is evenly equipped with four and installs hanging, wherein two are installed that hanging is positioned at above sidewall, two other installs hanging and be positioned at below sidewall, and sidewall are positioned at four positions of installing hanging centers and are provided with an anticreep hanging; The top of machine base body is provided with air intake cushion chamber, and the front end in air intake cushion chamber offers several air inlets communicated with support inner chamber.
Innovative point of the present utility model is stand structure and mounting means.Machine base body is that the spheroidal graphite cast-iron casting of high strength forms, main wall thick is the thinnest is 10mm, the interior muscle of support inner chamber uniform one week diversity, wind path between machine base body and stator core flows out in the middle of muscle in these diversities, reduce stator core temperature, interior muscle is provided with the boss of epirelief near the end of exit end, the unshakable in one's determination and machine base body axial location for located stator.Machine base body has a chow ring muscle for the intensity of enhanced machine seat body near air inlet.When the utility model support is installed, four in machine base body the center mounting hole middle installation node cover hung is installed, screw finally by node cover is installed on bogie, described node cover be by an inner ring be steel, centre is elastic caoutchouc, outer ring is the structure of steel, not only proof strength but also can damping.Node cover thickness is 30mm, and comparatively large with the area contacting machine base body, the area near center mounting hole is less, saves motor weight to greatest extent.The position thickness coordinated with node cover is 50mm.Complex-shaped, intensity is high.The weight of weight at the traction electric machine of about 700kg can be met, and the impact shock requirement of the bogie installation required by high speed motor car can be born.
The longitudinal section of described machine base body is positive six shapes.Inner chamber surrounding muscle is processed into circle, the structure of composition square-outside and round-inside.Can farthest save support size like this, and provide carrier for forming wind path between support and stator core.The thickness of support inner chamber is 10mm.
Described air intake cushion chamber and air inlet are positioned at machine base body top, and air intake cushion chamber is the air inlet that formation one is large above machine base body, and cooling air cushions after entering large air inlet, then enters motor internal from air inlet.Prevent the molecule in cooling air from directly entering into motor internal, cause stator insulation to damage.In air intake cushion chamber, air inlet casts two brace rods, can while enhanced machine seat body intensity, three-phase lead-out wire is separated outlet and fixing.
Described anticreep hanging is the parts for preventing motor from coming off, and the cross bar on bogie penetrates in anticreep hanging, prevents installing hanging inefficacy rear motor and comes off from bogie.
Described interior muscle, being for stator core and machine base body form wind path in one week, for cooling stator core, increasing the hexahedral intensity of support inner chamber simultaneously; Described ring muscle is the intensity in order to enhanced machine seat body.
Described ring muscle is the intensity in order to enhanced machine seat body, slows down the flow velocity of cooling air, cooling air is flowed in described interior muscle uniformly, can reach stator core Homogeneous cooling effect.
The utility model electric machine stand structure can effectively reduce motor weight and ensure its intensity, its structure can be utilized to realize wind path optimization simultaneously.When motor is installed, by installing node cover on electric machine stand, being then installed to the mode on bogie by node cover, there is shock-absorbing function, and simple, Yi Luoche is installed.
