Description
Technical field: the invention discloses a kind of be used for removing the sleet on the railway locomotive windshield and the device of dirt, a kind of specifically railway locomotive electric wiper.
Background technology: the railway locomotive electric wiper is by the motor branch unit, transmission gearbox branch unit, rain brush branch unit and the control part formation of grading, and it is to be used for removing the sleet on the windshield and the device of dirt.The Windshield Wiper that at present domestic and international locomotive is used has new type pneumatic wiper and two kinds of versions of electric wiper, existing railway locomotive electric wiper is because the general raising speed by a large scale of railway locomotive, there are many problems, be in particular in: distance is nearer when converging car owing to railway locomotive two cars, and the locomotive volume is big, the speed height so the impact air-flow resistance that produces when two cars move relatively strengthens, makes the existing electric wiper can't normal operation.
The material great majority of the transmission worm gear pair of current domestic and international locomotive electric wiper motor are to adopt polyformaldehyde, cast copper and cast iron materials, in using, the locomotive high-speed cruising exposes a lot of problems, be in particular in: because the insufficient strength of the problem worm gear of material, after having used a period of time, the wearing and tearing of worm gear and worm screw tooth form, the gap is big, noise is arranged, when two locomotive relative motions, at a high speed, wind speed is big, the broken teeth phenomenon also appears in most of worm gears, the distortion of worm screw tooth form.Terminal support sleeve and the steel ball of adopting of original in addition motor worm fixed, shortcoming be when the speed of a motor vehicle fast, when converging mutually, two cars make the terminal steel ball contact of worm screw two ends produce friction texturizing owing to wind-force is excessive, the gap is increasing, worm screw produces axial motion, strengthened noise during use, the tooth form of worm gear, worm screw produces distortion or fractures, and has influenced the normal operation and the service life of Windshield Wiper.
Summary of the invention: the objective of the invention is to provide a kind of worm gear to adopt the high hardness material, worm gear and worm screw are adopted the structure of thing free-running fit, do not produce that tooth form distortion and broken teeth phenomenon, noise are little, the railway locomotive electric wiper of long service life.
The object of the present invention is achieved like this: this Windshield Wiper comprises motor branch unit, rain brush branch unit, transmission gearbox branch unit, its motor branch unit links to each other with the transmission gearbox branch unit by the worm gear on it, the rain brush branch unit links to each other with the transmission gearbox branch unit, and the motor branch unit comprises housing, worm gear, worm screw, stator, armature.
Described motor branch unit also comprises radial bearing, thrust bearing, bearing carrier ring, is used for the end ring of adjusting play, two lobe collars, fixed cover.
Described worm gear and worm screw system adopt 45
#Steel, after heat treatment hardness is HR
c40～45.
Be worked into the size of requirement before the described worm gear heat treatment, do not keep surplus, do not reprocess after the heat treatment.
Keep stock left for machining before the described worm screw heat treatment, adopt special alloy cutter fine limit work after the heat treatment, reaching with worm gear does not have the requirement that the gap cooperates.
Described radial bearing, thrust bearing, bearing carrier ring, the end ring that is used for the adjusting play and fixed cover are arranged on the end of worm screw.
Described bearing carrier ring, radial bearing, thrust bearing are sleeved on the end of worm screw, and place, an End play of thrust bearing is set with end ring on worm screw, and the other end groove of end ring is provided with two lobe collars, and two lobe collars are fixed by fixed cover.
The present invention is owing to worm and gear adopts through hot-cured 45
#Steel matter, adopt no gap to cooperate between worm gear and worm screw, end worm screw is provided with radial bearing and thrust bearing, and fix by bearing carrier ring, the end ring that is used for the adjusting play, two lobe collars and fixed cover, so the tooth form of worm gear and worm screw does not produce distortion and fractures, no matter be just to change or reverse worm gear and worm screw do not produce axial motion, noise is little, long service life.Through the test cell analogue test, this electric wiper in-use performance is good, has satisfied the operating needs of express locomotive.
Description of drawings:
Fig. 1,2 is a railway locomotive electric wiper integral structure scheme drawing.
Fig. 3 is a motor branch unit integral structure cut-away view of the present invention.
The specific embodiment:
As described in accompanying drawing: this Windshield Wiper comprises motor branch unit 1, rain brush branch unit 2, transmission gearbox branch unit 3, its motor branch unit 1 links to each other with transmission gearbox branch unit 3 by the worm gear 5 on it, rain brush branch unit 2 links to each other with transmission gearbox branch unit 3, and motor branch unit 1 comprises housing 4, worm gear 5, worm screw 6, stator 7 and armature 8.
Described motor branch unit 1 also comprises radial bearing 9, thrust bearing 10, bearing carrier ring 11, is used for end ring 12, two lobe collars 13, the fixed cover 14 of adjusting play.
