Abstract
The utility model relates to an automobile gasoline engine flywheel which is composed of a fly wheel body, a toothed ring, a central hole and the like. The fly wheel body and the toothed ring are integrated to prevent the toothed ring which is prone to fall originally from falling. Thus, the using safety of the gasoline engine flywheel is improved. The fly wheel body is manufactured by forging 45 steel. The problems that a traditional HT 250 ash iron cast iron fly wheel is low in strength, poor in density, complex in mechanical machining, poor in weldability and the like are improved.
Description
Technical field:
The utility model relates to a kind of automobile component, specifically a kind of automobile gasoline machine flywheel.
Background technique:
We know; The material that the flywheel of present automobile gasoline machine generally uses is HT250; The flywheel body that this material casting processing forms has shortcomings such as weight is big, intensity is low, density difference, mechanical processing technique complicacy, weldability difference, and is easy to generate casting surface defective and inner phenomenons such as slag inclusion, pore and shrinkage porosite, has shortened the working life of flywheel; The probability that the gear ring obscission takes place is higher, causes badly damaged to petrol engine.
Summary of the invention:
The utility model technical problem to be solved is the deficiency that overcomes above-mentioned existing technology, provides that a kind of intensity is high, density is big, processing is simple, can thoroughly avoid the automobile gasoline machine flywheel of gear ring obscission.
The utility model solves the problems of the technologies described above the technological scheme of being taked: a kind of automobile gasoline machine flywheel; Comprise flywheel body, gear ring, tooth, Starter gear, center hole, petrol engine main shaft, it is characterized in that: the flywheel body outer annulus edge is provided with gear ring, and gear ring and flywheel body are structure as a whole; Gear ring is provided with several teeth; Gear ring and Starter gear are meshing with each other, and flywheel body is provided with center hole, and the petrol engine main shaft is installed in the center hole.
The said flywheel body of the utility model adopts 45 forgings to make and processes.
The utility model is owing to take said structure; Thoroughly avoid incident in the past gear ring obscission; Improved the safety in utilization of petrol engine flywheel; Process because of flywheel body adopts 45 forgings to make, improved problems such as traditional HT250 gray iron cast iron flywheel intensity is low, density difference, machining complicacy, weldability difference.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the flywheel body plan view of the utility model.
Be labeled as among the figure: 1. flywheel body, 2. gear ring, 3. tooth, 4. Starter gear, 5. center hole, 6. petrol engine main shaft.
Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be further described:
Like Fig. 1, shown in Figure 2, the utility model relates to a kind of automobile gasoline machine flywheel, comprises flywheel body 1, gear ring 2, tooth 3, Starter gear 4, center hole 5, petrol engine main shaft 6; It is characterized in that: flywheel body 1 outer annulus edge is provided with gear ring 2, and gear ring 2 is structure as a whole with flywheel body 1, and gear ring 2 is provided with several teeth 3; Gear ring 2 is meshing with each other with Starter gear 4; Flywheel body 1 is provided with center hole 5, and petrol engine main shaft 6 is installed in the center hole 5, and flywheel body 1 adopts 45 forgings to make and processes.
The flywheel body of the utility model processes because of adopting 45 forgings to make; After Quenching Treatment; Improved tooth portion hardness, tooth portion hardness generally can reach HRC40-50, has improved problems such as traditional HT250 gray iron cast iron flywheel intensity is low, density difference, machining complicacy, weldability difference.
