Abstract
The utility model relates to a crank pulley of a 1.0-liter gasoline engine. A pulley body is formed by spin forming of a steel plate, a disc-shaped indent part is arranged in the middle part of the front end of the pulley body, a disc-shaped reinforcing sheet is welded at the indent part in the middle part of the front end of the pulley body, three positioning bosses are uniformly distributed on the pulley body at the reinforcing sheet part and the reinforcing sheet correspondingly, and the positioning bosses are raised toward one side of a crank. The crank pulley dispenses with rubber component, has the tensile strength being greatly higher than that of a cast iron material, is manufactured by spinning technique, has simple from and structure, light weight, good balancing performance and high density of surface texture, is beneficial to prolonging the service life of a belt and reducing the manufacturing cost and meets the light design requirement of an engine; the reinforcing sheet is welded, thus guaranteeing the using strength and enabling the crank pulley to be connected reliably; simultaneously, the crank pulley has simple structure, saves material and is easy to process; the three punched positioning bosses are used for radial positioning, thus saving material, enabling the crank pulley to be positioned accurately and assembled easily.
Description
Technical field
The utility model belongs to technical field of internal combustion engines, is specifically related to the displacement gasoline engine crank pulley.
Background technique
In recent years, the prices of raw and semifnished materials rise steadily, and the automobile industry competition is more and more fierce, how to save material under the prerequisite that does not influence quality of product and working life, reduces cost, alleviates engine weight, more and more are subjected to the technician and pay attention to.Traditional crank pulley adopts cast iron materials, complex manufacturing, and in casting process, be easy to generate quality inhomogeneous (sand holes, pore etc.) defective, balance is bad.Under the support energetically of policy aspect the national energy-saving and emission-reduction, small displacement engine is more and more welcome on the other hand.Simultaneously, the small displacement engine vibratility is less than large-duty engine, and some motors do not need can satisfy by the cushioning effect of crank pulley the requirement of vibrations aspect.
The model utility content
In order to satisfy the vibration standard of small displacement engine, the utility model provides a kind of coupling 1.0L petrolic crank pulley.
Concrete organization plan is as follows:
The petrolic crank pulley of a kind of 1.0L comprises the pulley body of steel plate rotary press modelling, and the pulley groove number is 5, and the middle part of its front end is the inner concave shape of plate-like; Recess is being welded to connect the reinforced sheet of plate-like in the described pulley body, and correspondence is laid with 3 positioning boss on the pulley body at reinforced sheet place and the reinforced sheet, and described positioning boss is to bent axle one side projection.
Described positioning boss is oval, and it highly is 2mm, and the length of long axis direction is 7-9mm, and the length of short-axis direction is 4-6 mm.
Useful technique effect of the present utility model embodies in the following areas:
1, the utility model cancellation rubber constituent, adopt steel plate materials, tensile strength is much higher than cast iron materials, make through spinning process, type structure is simple, light weight, balance quality is good, surface texture density height in the working life that helps improving belt, reduces manufacture cost and realizes the requirement of motor light-weight design.By at pulley body welding reinforced sheet, guarantee working strength, connect reliably, simultaneously simple in structure, material saving, easily processing.
2, this belt pulley carries out radial location by three positioning boss that stamp out, and saves material, and the location accurately is easy to assembling.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the sectional view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described by embodiment.
Embodiment:
Referring to Fig. 1 and Fig. 2, the petrolic crank pulley of a kind of 1.0L comprises the pulley body 2 of steel plate rotary press modelling, and its thickness is 22mm, and maximum outside diameter is Φ 153mm, and internal diameter is 138.5mm, and the pulley groove number is 5.The middle part of its front end is the interior recess of plate-like, promptly begins to the crankshaft side indent from about diameter of phi 85mm, is plane trying to get to the heart of a matter in the scope of the central diameter Φ 68.5mm left and right sides, and the amount of unbalance of trying to get to the heart of a matter is 12g.cm to the maximum.Recess is being welded to connect the reinforced sheet 3 of plate-like in it, and correspondence is laid with 3 positioning boss 1 on the pulley body 2 at reinforced sheet place and the reinforced sheet 3, and positioning boss 1 assembles radial location to bent axle one side projection by 3 boss.Positioning boss 1 is oval, and it highly is 2mm, and the length of long axis direction is 7-9mm, and the length of short-axis direction is 4-6 mm.
Claims (2)
