Abstract
The utility model provides a take spring seat formula isolator for internal-combustion engine starter sets up a plastics spring holder between roller and supporting spring, and this plastics spring holder length matches with the roller, and there is the concave groove that matches with the roller on plastics spring holder upper portion along roller length direction, and there is the boss that supporting spring embolias in the lower part. An oil storage tank is arranged on the concave groove at the upper part of the plastic spring seat. The concave groove on the upper part of the plastic spring seat is a part of cylindrical surface, a part of elliptic cylindrical surface or a concave groove with a trapezoidal section matched with the roller. Through design a plastics spring holder between isolator spring and roller, change pure metal contact into centre and add nonmetal transition, become the line contact and become the face contact, the axial stability of multiplicable roller and the axial stability of spring help improving the wearability to improve the reliable durability of isolator, the durability life-span is improved to 40000 times by present industry standard 20000 times.
Description
Technical field
The utility model relates to a kind of starter motor for internal combustion engine with being with spring seat formula one-way element.The utility model mainly is installed on the starter motor, is used for cranking internal combustion engine.
Background technique
In the prior art, the common roller type one way device of the most of employing of starter motor for internal combustion engine skids easily and flat spring annealing was lost efficacy, and rate of fault is higher, causes defective starter, can't starting apparatus combustion engine.
Summary of the invention
The purpose of this utility model is to provide a kind of starter motor for internal combustion engine of viability with being with spring seat formula one-way element.
The technical solution of the utility model is: starter motor for internal combustion engine of the present utility model is with being with spring seat formula one-way element, comprise roller and supported spring thereof, one plastics spring seat is set between roller and supported spring, this plastics spring seat length and roller coupling, plastics spring seat top is the Baltimore groove that mates with roller along the roller length direction, the boss that the bottom has supported spring to be inserted in.
Described starter motor for internal combustion engine is with being with spring seat formula one-way element, and the Baltimore groove on plastics spring seat top is provided with oil storage tank.
The Baltimore groove on described plastics spring seat top is the part cylndrical surface of mating with roller.
The Baltimore groove on described plastics spring seat top is the part elliptic cylinder that mates with roller.
The Baltimore groove on described plastics spring seat top is that the cross section with roller coupling is trapezoidal Baltimore groove.
Advantage of the present utility model: by design one plastics spring seat between one-way element spring and roller, this part is provided with oil storage tank, change the pure metal contact into the middle nonmetal transition that adds, can reduce because roller directly contacts high speed rotating with spring friction generates heat, cause spring annealing to lose efficacy, spring directly contacts with roller simultaneously, be the line contact, change the face contact into after adding the plastics spring seat, can increase the axial stability of roller and the axial stability of spring, help to improve wear resistance, thereby improve the reliable durable of one-way element, viability is brought up to for 20000 times 40000 times by present industry standard.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a plastics spring seat worm's eye view.
Fig. 3 is a plastics spring seat plan view.
Fig. 4 is a kind of embodiment's plastics spring seat cross-sectional view.
Fig. 5 is another kind of embodiment's plastics spring seat cross-sectional view.
Embodiment
As Fig. 1, Fig. 2, Fig. 3: the utility model is provided with a plastics spring seat 3 between roller 1 and supported spring 2, this plastics spring seat length and roller coupling, the cylndrical surface on plastics spring seat top is provided with oil storage tank 3.1, the boss 3.2 that the bottom has supported spring to be inserted in.
As Fig. 4, Fig. 5: there is Baltimore groove 3.3 with the roller coupling on plastics spring seat 3 tops along the roller length direction, and oil storage tank 3.1 is in Baltimore groove 3.3.The boss 3.2 that the bottom has supported spring to be inserted in.
The Baltimore groove that Fig. 4 provides plastics spring seat top is part cylndrical surface or the elliptic cylinder that mates with roller.The Baltimore groove that Fig. 4 provides plastics spring seat top is that the cross section that roller mates is trapezoidal Baltimore groove.
The plastics spring seat is according to one-way element volume size, and be connected with the one-way element spring and can adopt multiple structural type, as: groove type, single cylindrical formula, elliptic etc.
Core of the present utility model is that a plastics spring seat is set between roller and supported spring, adds nonmetal transition in the middle of the pure metal contact is changed into, with the line contact, becomes the face contact.Therefore, every plastic barrier parts of being provided with between roller and supported spring all belong to protection domain of the present utility model.
