Abstract
The utility model discloses a power generator without a bearing cap. Front and rear bearings of common small-sized power generators are covered by bearing caps to prevent dust, seal and position an external circumference of the bearing, thus increasing power generator cost and undergoing difficult internal bearing cap mounting. However, the utility model eliminates front and back bearing cap and applies to the medium and small-sized power generator field, thus simplifying power generator production, lowering cost, reducing axial size of the power generator, decreasing weight, ensuring a nice appearance, and improving market competitiveness of the power generator.
Description
Technical field
The utility model relates to power-supply device, is particularly suitable for small generator, is a kind of no bearing cap generator.
Background technology
Generally the small generator front and back bearings all adopts bearing cap to carry out dust seal, and bearing outer ring is carried out axial location, has so not only increased the cost of generator, and internal bearing cover installation difficulty, is not easy to the general assembly and the maintenance of generator.Just can overcome above-mentioned shortcoming if can cancel the front and back bearings lid, the utility model produces for achieving the above object just.
Summary of the invention
The purpose of this utility model is to provide a kind of no bearing cap generator, and this generator can realize that front and back bearings does not all need bearing cap to carry out dust seal and axial location.
The technical solution of the utility model is: a kind of no bearing cap generator, this generator comprises front end housing, fore bearing, protective cover, rotor, stator, protective cover, rear bearing, rear end cap, wavy spring packing ring, protective cover, the front and back bearings of this no bearing cap generator all adopts the deep groove ball bearing of two sides band sealing ring, rely on the shoulder of front and rear cover that bearing outer ring is carried out axial location respectively, there is not the front and back bearings lid, the rear end cap bearing chamber is adorned a wavy spring packing ring, is used for mending the axial endplay of tasting rotor.
Advantage of the present utility model is: this technology is applied to the small generator field, can make the generator manufacturing simple, and cost descends, and simultaneously the generator axial dimension is reduced, weight saving, and good looking appearance improves the generator competitiveness of product in market.Owing to use the deep groove ball bearing of two sides band sealed picture, do not need the front and back bearings lid, the manufacturing cost of having saved four bearing caps, the general assembly that makes generator simultaneously is simple and fast more, and its economic benefit is conspicuous.
