Abstract

The utility model relates to an energy-storage flywheel being made of iron-plastic composite material, which is characterized in that only the outermost wheel hoop of the flywheel is made of steel, and the internal wheel belly part is made of the plastic composite material which is formed in a thermosetting way. The inner circle of the wheel hoop part is provided with a reversed dovetail groove which is matched with the wheel belly part in a limiting way so as to ensure the application performance of the flywheel. The energy-storage flywheel has the advantages of light weight and low cost.

Description

The energy storage flywheel that a kind of iron plastic composite materials is made

Technical field

The utility model relates to the mechanical energy storage flywheel that a kind of iron plastic composite materials is made, this flywheel applications in mechanical energy storage device as energy storage unit.

Background technique

Machinery energy storage flywheel is a kind of common mechanical part; The rotary inertia of preserving on flywheel when its main effect is utilization mechanical flywheel high speed rotating is preserved mechanical energy, so that mechanical system reaches steady rotating speed, improves shock resistance, the effects such as energy loss that produce when when reducing the mechanical system Fraquent start requirement of starting torque being reduced to brake.According to relevant physics theorem as can be known the energy of flywheel storage be directly proportional with the quality of flywheel; For the performance that improves flywheel allows the common flywheel of flywheel storage more energy need bigger quality; Mechanical flywheel all is to make with iron and steel without exception in order to achieve the above object.Because steel in recent years appreciate, the flywheel manufacture cost constantly goes up directly influences manufacture cost.

Do not reduce the performance of flywheel when how to reduce manufacture cost again, depend on that quality is in flywheel distribution on the whole when the rotary inertia of flywheel depends on flywheel mass under the situation of same rotational speed as can be known according to the physics law of correlation yet; The mass distribution far away more apart from center of rotation is big more to the contribution of rotary inertia, and near more mass distribution is more little even be zero to the contribution of rotary inertia apart from the center.In order to improve the utilization ratio of material, flywheel design as much as possible with mass distribution on position far away, distance center, to obtain rotary inertia to greatest extent.

Summary of the invention

The utility model is distributed to apart from center of rotation wheel outer ring far away according to the correlative principle of science ferrous materials that quality is bigger, makes every effort to obtain under equal quality bigger rotary inertia; With respect to a distance axle nearer part lighter weight price relatively low composite plastic manufacturing less to the rotary inertia contribution, the use value that makes full use of material is saved manufacture cost.

The technological scheme that its technical problem that will solve the utility model adopts is: utilization iron plastic composite materials manufacturing machine flywheel, partly use the big ferrous materials of intensity high quality to make the flywheel rim at, the higher flywheel outmost turns rim of requirement of strength big and guaranteed the requirement of flywheel rotary inertia to the rotary inertia contribution, less, the less demanding flywheel inner wheel of structural strength tripe is partly reduced cost with the relatively low composite plastic manufacturing of price to the rotary inertia contribution.Manufacturing has the energy storage flywheel to it is characterized in that the whole rounded structure of flywheel, outmost turns is the rim that iron and steel or other metallic material are made, rim is that plastic composite solidify to form the wheel tripe partly through hot injection moulding with interior part, and rim partly forms flywheel integral body with the wheel tripe in the thermoset forming process.

The obtained beneficial effect of the utility model is: the energy storage flywheel of making same rotary inertia has reduced expensive metallic material use amount greatly when not influencing its service behaviour, when having reduced manufacture cost, also alleviated the weight of flywheel greatly, helped flywheel to use this mechanical device of energy storage flywheel to improve mechanical property in some occasions that machinery weight is had relatively high expectations.

Description of drawings

Fig. 1 is a radial cross-section of the present utility model.

Fig. 2 is a flywheel front outline drawing.

Fig. 3 is the rim radial cross-section.

Fig. 4 is the axial view of rim.

1 is the rim part, the 2nd of ferrous materials manufacturing among the figure, and the wheel tripe part, the 3rd of thermoplastic plastic composite material manufacturing is carried out the ventilation blade that thermoforming is processed to form to composite material.

Embodiment

At first become the flywheel rim part of Fig. 3, Fig. 4 shape with the bigger iron and steel manufacturing of quality, Fig. 3 is that radial cross-section, Fig. 4 of rim is the axial view of rim.

Secondly be injection molded in the pattern being placed on after the rim preheating, in the rim central space, inject composite plastics material 2, thermoset forming takes place thermosetting composite plastics material 2 in the middle of making through the heat cure moulding again and rim 1 ferrous materials forms a complete integral body, thereby finish the manufacturing of whole flywheel.As shown in Figure 1 among the figure 1 for the rim of iron and steel manufacturing partly, 2 for composite plastics material through the wheel tripe of heat cure moulding partly, the 3rd, the ventilation blade that forms behind the composite plastics material thermoset forming plays the adjection that ventilates and cool off when flywheel rotates.

Because iron and steel is different with the ratio of expanding with heat and contract with cold of plastics, the rim that inevitably can cause the iron and steel manufacturing in long-term use partly produces loosening the separation with the wheel tripe of inner composite plastic thermoset forming, the utility model is designed to the shape of falling the dovetail groove with the rim inner ring, preheat simultaneously and go the injection heat solidifying after making it heat expansion take place increase diameter again, make back iron and steel rim in integral body and shrink because of cooling that the formation interference fit adds down that the position-limiting action of dovetail groove has effectively overcome the overall performance that loosening phenomenon has guaranteed flywheel between the wheel tripe with compound plastic material thermoset forming at the rim of before the molding and forming iron and steel being made.

Use the mechanical energy storage flywheel of the utility model manufacturing only partly to use ferrous materials at the flywheel rim, all the other composite plastics materials that partly all operating weight is light, price is low even can use the waste or used plastics made of recovery, thus the weight of flywheel when satisfying performance, greatly reduced and manufacture cost that manufacture cost, a large amount of steel of saving have reduced energy storage device integral body improves competitiveness of product.
