Abstract
A bearing protection device of an outer fan generator used for a desert area is disclosed. An inner side of a bearing baffle plate in the generator is a concave conical surface. A dustproof bushing is arranged between the bearing baffle plate and a motor rotor. The dustproof bushing is provided with a conical surface which is cooperated with the concave conical surface of the bearing baffle plate, a gap is 0.5mm and the conical surface is pressed and installed on a motor rotor shaft. A groove is arranged on a circumferential surface of the dustproof bushing. A zigzag dust cover is arranged outside a motor end cap and the gaps between the motor end cap and the zigzag dust cover and between the fan and the zigzag dust cover are less than 0.5mm. A dustproof cover plate is arranged on the inner side of an output end bearing end cap of a motor body. A possibility for sand and dust to enter into the bearing is greatly reduced. A clearance fit of the bearing baffle plate and the concave conical surface of the dustproof bushing is 0.5mm so as to prevent the dust from entering. A structure is simple. The bearing protection device is mainly used in a driving end of the outer fan generator. By using a dustproof structure of a centrifugal force bearing, a mount of the sand and dust which enter into the bearing can be greatly reduced so that a service life of the generator in the desert area increases to one year from two months. Generator durability is greatly improved.
Description
Technical field
The utility model relates to bearing protecting device, specifically is a kind of bearing protecting device that is used for desert area external fan generator.
Background technology
In the prior art, most of automobile does not adopt dustproof construction with external fan alternative electric generation machine bearing, and in desert area, the environment for use of generator is comparatively abominable, and sand and dust are prone to get in the bearing, cause the grease sintering, thereby cause bearing early failure failure rate higher.
Summary of the invention
The utility model purpose is the desert area automobile with external fan alternating current generator bearing protection, improves the useful life of bearing, specially proposes a kind of bearing protecting device that is used for desert area external fan generator.
The technical scheme of the utility model does for this reason, and a kind of bearing protecting device that is used for desert area external fan generator comprises the generator body; Rotor, on electric motor end cap, the bearing inboard is provided with bearing baffle through bearing fixing at the two ends of rotor; It is characterized in that: said bearing baffle inboard is the concave cone face; Be provided with dustproof lining between bearing baffle and the rotor, the concave cone face that dustproof lining is provided with the conical surface and bearing baffle cooperates, and is fitted on the rotor axis of electric.
Improvement to such scheme is: the concave cone face of bearing baffle and dustproof lining concave cone face fit clearance are 0.5mm.
Improvement to such scheme is: dustproof lining periphery is provided with groove.
Improvement to such scheme is: outside electric motor end cap, be provided with " it " font dust cover, the gap of " it " font dust cover and electric motor end cap and fan is less than 0.5mm.
Improvement to such scheme is: the output bearing (ball) cover inboard at motor body is provided with dust cover.
Beneficial effect:
The dustproof lining of the utility model greatly reduces the possibility that sand and dust get into bearing; The bearing baffle conical surface and dustproof lining concave cone face fit clearance are 0.5mm, have prevented the entering of dust.
Dustproof lining periphery has been provided with a groove, and the dust that major part is flown to dustproof lining is stopped that by dustproof lining groove the lining that is rotated throws away.
Outside electric motor end cap, be provided with " it " font dust cover; The gap of " it " font dust cover and electric motor end cap and fan is less than 0.5mm; Because the distance of dust this moment and complications; Adopt centrifugal protection structure, sand and dust can't get in the bearing basically, thereby have improved the bearing protection ability.
Being provided with dust cover in the output bearing (ball) cover inboard of motor body then is in order to prevent that dust from oppositely getting into.
The utility model is simple in structure; Be mainly used in external fan generator drive end, centrifugal force type bearing dustproof construction has reduced sand and dust largely and has got in the bearing; Make generator rise to 1 year by 2 months, improved generator endurance greatly in the useful life of desert area.
