Abstract
The utility model relates to a starter isolator with a spring protecting jacket, solving the problems of easy bending, breakage, damage, idle running and skidding of the existing starter isolator. The starter isolator with the spring protecting jacket comprises an isolator, a guide sleeve, a roller and a spring and is characterized in that one end of the spring is supported on a convex platform in the guide sleeve, and the spring protecting jacket is installed between the spring and the roller; the surface of the spring protecting jacket, which comes in contact with the roller, is cambered so as to enlarge the contact area between the spring protecting jacket and the roller; and the surface of the spring protecting jacket, which comes in contact with the roller, is provided with an oil storage tank so as to improve the lubrication condition. The starter isolator with the spring protecting jacket has the advantages that the spring is supported on the convex platform in the guide sleeve so as to improve the working stability of the spring; and the spring protecting jacket is arranged between the roller and the spring, line contact between the spring protecting jacket and the roller is changed into surface contact, and the lubrication condition is improved, therefore the working reliability of the isolator is improved and the service life of the starter is prolonged.
Description
Technical field
The utility model belongs to a kind of vehicle-mounted starting machine parts, particularly a kind of starter motor one-way element with the spring protection cover.
Background technique
Existing starter motor mainly is made of parts such as driving end cap, one-way element, planet wheel shaft, armature, casing, carbon brush, brush bonnet, magnetic switch.When starter motor was started working, electric current flowed into armature by anodal carbon brush, and armature rotates under the effect in magnetic field, and drove one-way element and rotate together, and one-way element ejects under the effect of magnetic switch.Existing vehicle-mounted starting machine one-way element is generally common roller type one way device, and as shown in Figure 6, it mainly is made of one-way element 1, guide sleeve 2, roller 3 and spring 5 etc.One end bearing of spring 5 has on the boss of radian in guide sleeve 2 inside, and the other end directly contacts with roller 3.The subject matter that this one-way element exists is that because spring 5 directly contacts with roller 3, roller 3 can cause bigger impact to spring 5 when rolling back and forth.In addition, because spring 5 is not the plane with the contacting point of guide sleeve 2, when one-way element 1 high speed rotating, phenomenon crooked, that fracture even damage can appear in spring 5, cause roller 3 rotary work that neck bush and sleeve can not be linked together, and normal sense of rotation slipping occurs, can damage each parts when serious, cause defective starter, can't cranking internal combustion engine.
Summary of the invention
The technical problems to be solved in the utility model is; overcome the spring that existing starter motor one-way element exists crooked easily, fracture, damage, and the problem of slipping, the starter motor one-way element of a kind of spring good stability, band spring protection cover that the one-way element functional reliability is high is provided.
The utility model comprises one-way element, guide sleeve, roller and spring, and its special way is that an end bearing of spring is equipped with the spring protection cover on the platform of guide sleeve internal protrusion between spring and roller.
The spring protection cover is an arc shaped surface with the contacted surface of roller, so that increase the area of contact of spring protection cover and roller.
On spring protection cover and the contacted surface of roller, hold oil groove in addition, to improve lubricating condition.
In spring protection cover, also have a spring positioning boss, preventing spring play in the spring protection cover, the stability when improving spring work, in the spring positioning boss in addition one with hold the oil storage hole that oil groove communicates, with the storage more lubricating oil.
Advantage of the present utility model is:
1, spring-loaded is on the platform of guide sleeve internal protrusion, and the supporting of spring steadily, has reliably guaranteed that spring can not occur crooked and the phenomenon that fractures, and has improved the stability of spring work.
2, the spring protection cover is set between roller and spring; and the spring protection cover is an arc shaped surface with the contacted surface of roller; and oil groove is held in setting on spring protection cover and the contacted surface of roller; spring protection cover contact with line between the roller become face and contact; increase area of contact, improved the stability between roller and the spring, improved lubricating condition; thereby improved the reliability of one-way element work, prolonged the working life of starter motor.

Embodiment
As Fig. 1, Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5, the utility model comprises one-way element 1, guide sleeve 2, roller 3 and spring 5, there are several protruding platform 2a the inside of guide sleeve 2, one end bearing of spring 5 is on the platform 2a of guide sleeve 2, spring protection cover 4 is housed between spring 5 and roller 3, spring protection cover 4 is cups of a rectangle, and spring protection cover 4 can be made of metal, also can use nonmetal making; Described spring protection cover 4 is arc shaped surface 4a with roller 3 contacted surfaces, so that increase the area of contact of spring protection cover 4 and roller 3; On spring protection cover 4 and roller 3 contacted surfaces, hold oil groove 4b in addition, to improve lubricating condition; In spring protection cover 4, also has a spring positioning boss 4c, to prevent spring 5 play in spring protection cover 4, the stability when improving spring 5 work; In spring positioning boss 4c, also have one with hold the oil storage hole 4d that oil groove 4b communicates, to store more lubricating oil, guarantee to lubricate reliably between spring protection cover 4 and the roller 3.
Claims (4)
