Abstract
The invention discloses a protection electrical appliance with an automatic reclosing function. The protection electrical appliance comprises a motor and a gear. A through hole is arranged in the middle of the gear. The through hole of the gear sleeves a motor shaft of the motor. A one-way bearing is arranged in the through hole of the gear. According to the invention, the manufacturing cost of a product is reduced without affecting the product performance; the gear is made of nylon and fiberglass, polytetrafluoroethylene or polyphenylene sulfide, has the advantages of strong toughness, high temperature resistance and wear resistance, and has a self-lubricating function; during operation, the gear has the advantages of wear resistance and smooth motion; through the one-way bearing, the problem of idle stroke is solved; and integrated assembly is simple and reliable.
Description
Technical field
The present invention relates to low-voltage circuit breaker, be specifically related to a kind of integral type gear Unidirectional structure with the protective device of automatic reclosing function.
Background technology
The protective device with automatic reclosing function is used for carrying out indirect contact protection to people; also can be used to prevent because of apparatus insulated damage; produce earth fault current and the fire hazard that causes; and can be used to the overload and the short circuit that distribute electric energy and protection circuit and power-supply device, also can be used as the use that the infrequently conversion of circuit and motor infrequently start.This serial protective device is used for the upgrading of rural power grids; it acts frequently; therefore require higher to its operational structure; in existing product, the ratchet structure of driven gear running is loaded down with trivial details; assembling is complicated, easy to wear, and when energising runs; could operate by driven gear after driven by motor ratchet idle running LAP, add product closing time.
Summary of the invention
The manufacturing cost of product is reduced under the object of the present invention is to provide a kind of prerequisite not affecting properties of product; Gear is that nylon material adds glass or polyphenylene sulfide or polytetrafluoroethylene and makes, and toughness is comparatively strong, high temperature resistant, and resistance to wear is strong and have self-lubricating function, not easy to wear in operation process, stable movement; Unilateral bearing solves the problem of bar stroke; Assemble the simple and reliable protective device with automatic reclosing function.
Technical scheme of the present invention is; there is a protective device for automatic reclosing function, comprise motor and gear, in the middle of described gear, be provided with through hole; the through hole of described gear is nested with on the motor shaft of described motor, is also provided with a unilateral bearing in the through hole of described gear.
In a preferred embodiment of the present invention, described gear and described unilateral bearing interference fit also form integral structure.
In a preferred embodiment of the present invention, described gear upper surface side is also protruding upward is provided with an inserts and three reinforcements.
In a preferred embodiment of the present invention, described gear adopts nylon material to add glass or polyphenylene sulfide or polytetrafluoroethylene and makes.
In a preferred embodiment of the present invention, when the energising of this protective device runs, driven by motor unilateral bearing and gear operate clockwise and realize protective device splitting or integrating lock and without bar stroke.
Of the present invention is a kind of protective device with automatic reclosing function, and the present invention reduces the manufacturing cost of product under the prerequisite not affecting properties of product; Gear is that nylon material adds glass and makes, and toughness is comparatively strong, high temperature resistant, and resistance to wear is strong and have self-lubricating function, not easy to wear in operation process, stable movement; Unilateral bearing solves the problem of bar stroke; Integral type assembling is simple and reliable.
Accompanying drawing explanation
Fig. 1 is a kind of front section view had in protective device one preferred embodiment of automatic reclosing function of the present invention;
Fig. 2 is a kind of vertical view had in another preferred embodiment of protective device of automatic reclosing function of the present invention.
Embodiment
Below preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Of the present invention is a kind of protective device with automatic reclosing function, as shown in Figure 1 with Figure 2, comprises motor 1 and gear 2, and be provided with through hole in the middle of described gear 2, the through hole of described gear 2 is nested with on the motor shaft 3 of described motor 1.
A unilateral bearing 4 is also provided with in the through hole of described gear 2.
Described gear 2 is with described unilateral bearing 4 interference fit and form integral structure.
When residual current circuit breaker energising runs, motor 1 drive unilateral bearing 4 and gear 2 clockwise running realize residual current circuit breaker splitting or integrating lock and without bar stroke.
Described gear 2 upper surface side is also protruding upward is provided with an inserts 5.
Described gear 2 upper surface side is also protruding upward is provided with three reinforcements 6.
Described gear 2 adopts nylon material to add glass or polyphenylene sulfide or polytetrafluoroethylene and makes.
Together load motor 1 after unilateral bearing 4 and gear 2 interference fit, when the energising of this protective device runs, motor 1 drives unilateral bearing 4 and gear 2 to operate clockwise, realizes protective device splitting or integrating lock; Gear 2 and unilateral bearing 4 combine together, be convenient to assembling, and smooth running, unilateral bearing 4 plays a part to prevent gear 2 from reversing and not having bar stroke, gear 2 adopts high temperature resistant, that resistance to wear is strong nylon material to add glass or polyphenylene sulfide or polytetrafluoroethylene, unilateral bearing needle roller adopts metallic article, and hardness is high, and the life-span is long.
Of the present invention is a kind of protective device with automatic reclosing function, and the present invention reduces the manufacturing cost of product under the prerequisite not affecting properties of product; Gear is that nylon material adds glass or polyphenylene sulfide or polytetrafluoroethylene, and toughness is comparatively strong, high temperature resistant, and resistance to wear is strong and have self-lubricating function, not easy to wear in operation process, stable movement; Unilateral bearing solves the problem of bar stroke; Integral type assembling is simple and reliable.
The foregoing is only the specific embodiment of the present invention; but protection scope of the present invention is not limited thereto; any those of ordinary skill in the art are in the technical scope disclosed by the present invention; the change can expected without creative work or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection range that protection scope of the present invention should limit with claims is as the criterion.
