Abstract
The utility model discloses a motor collector ring protective sleeve, and relates to a technical appliance in motor production. The protective sleeve is a cylindrical body. The length of an inner cavity of the protective sleeve is longer than the length of a shaft end section. The internal diameter of the protective sleeve is bigger than the external diameter of the shaft end section. An internal wall of the protective sleeve extends inward so as to form three radial reinforcing plate strips which are uniformly arranged and are conjoined with the inner wall. The diameter formed by front edges of the three reinforcing plate strips is smaller than the external diameter of the shaft end section. The center of a bottom cover of the protective sleeve cylindrical body is provided with a through hole. The advantage of the motor collector ring protective sleeve is that the protective sleeve can be sleeved on the shaft end section firmly and easily.
Description
Technical field:
The utility model relates to the technology apparatus in the motor production, particularly a kind of motor collecting ring protective sleeve.
Background technology:
The axle head section of motor shaft is fixed with when two copper collector rings are used for the motor shaft rotation conducts electricity.In the production, after two collector ring fixed installations were good, the unavoidable generation collided with in subsequent handling, collector ring caused scratch or damage, and therefore in production procedure, will put a protective sleeve after collector ring installs.
The prior art protective sleeve is shaped as tubular body, and its internal diameter equates with the axle head section that in theory interior cavity length is slightly larger than the axle head segment length, and protective sleeve puts back one of which end and withstands on the shaft shoulder at axle head section rear portion.Existing protective sleeve material is generally papery or plastics matter, and its inner chamber internal diameter can't guarantee and the tight fit of axle head section, and the inner chamber internal diameter is little, and cover does not get on, and big can produce obscission, is difficult to guarantee the just suitable not only good cover of size but also does not come off.After protective sleeve put, also there was the foreign material scraping in outer end opening.
Summary of the invention:
The purpose of the utility model is to overcome above-mentioned defective, and a kind of motor collecting ring protective sleeve is provided.
The scheme of the utility model is: it is characterized in that: protective sleeve is a cylindrical body; Cavity length is greater than the axle head segment length in the protective sleeve; The protective sleeve internal diameter is greater than axle head section external diameter; The inside disjunctor of protective sleeve inwall is uniformly distributed with three the radial rib laths that extend, and the diameter that three gusset bar forward positions are surrounded is less than axle head section external diameter; The bottom central authorities of protective sleeve tubular body are provided with through hole.
The advantage of the utility model is: protective sleeve and axle head section fit, and not only laborsaving but also guarantee to be locked.
Description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 is the A-A cutaway view of Fig. 1.
Embodiment:
The structure of the utility model is characterized in that: protective sleeve 1 is cylindrical body; Cavity length is greater than axle head section 3 length in the protective sleeve 1; Protective sleeve 1 internal diameter is greater than axle head section 3 external diameters; The inside disjunctor of protective sleeve 1 inwall is uniformly distributed with three the radial rib laths that extend, and the diameter that three gusset bar forward positions are surrounded is less than axle head section 3 external diameters; The bottom central authorities of protective sleeve 1 cylindrical body are provided with through hole.
Radial rib lath radial height is 0.3-0.5mm.
Plastics quality guarantee sheath 1 is injection molded on injection molding machine, and three gusset bars overlap fashionable generation strain, can be backward or oblique compression, therefore guarantee to fix with axle head section 3 tight contacts.The setting of bottom through hole is for protective sleeve 1 is inserted in the stroke, and cover inner chamber air is leaked by through hole, avoids inner chamber generation air compression to make and is inserted in effort, and it is easy for installation to improve work efficiency, has guaranteed that again collector ring 2 does not expose.
Claims (2)
