The utility model discloses the manufacturing cost of product has been reduced under the prerequisite that does not influence properties of product, the gear is made for the nylon material adds glass fibre or polyphenylene sulfide or polytetrafluoroethylene, and toughness is stronger, and is high temperature resistant, and strong resistance to abrasion just has the self -lubricating function, at the difficult wearing and tearing of operation in -process, motion stationary, the problem of the free journey of changing one's profession has been solved to one -way bearing, the integral type assembly is simple reliable.
Description
Technical field
The utility model relates to low-voltage circuit breaker, is 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.
Utility model content
The purpose of this utility model reduces the manufacturing cost of product under being 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.
The technical solution of the utility model 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 the utility model preferred embodiment, described gear and described unilateral bearing interference fit also form integral structure.
In the utility model preferred embodiment, described gear upper surface side is also protruding upward is provided with an inserts and three reinforcements.
In the utility model preferred embodiment, described gear adopts nylon material to add glass or polyphenylene sulfide or polytetrafluoroethylene and makes.
In the utility model preferred embodiment, 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.
Described in the utility model is a kind of protective device with automatic reclosing function, and the utility model 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 utility model;
Fig. 2 is a kind of vertical view had in another preferred embodiment of protective device of automatic reclosing function of the utility model.
Embodiment
Below preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection range of the present utility model.
Described in the utility model 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.
Described in the utility model is a kind of protective device with automatic reclosing function, and the utility model 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 embodiment of the present utility model; but protection range of the present utility model is not limited thereto; any those of ordinary skill in the art are in the technical scope disclosed by the utility model; the change can expected without creative work or replacement, all should be encompassed within protection range of the present utility model.Therefore, the protection range that protection range of the present utility model should limit with claims is as the criterion.
