Abstract
Disclosed is an improved flywheel body with a damping device, which comprises a wheel flange (1), H-shaped wire spokes (2), screws (3), friction plates (4), damping rings (5), a supporting bushing (8), screw bolts (7) and a wheel hub (8), wherein five H-shaped wire spokes are partitioned by a same angle, which are welded with the wheel hub and are fixed by the screws, and thereby an improved flywheel is formed. Two damping rings are fixed on ten small bosses which are separated by the five H-shaped wire spokes arranged on an inner diameter wall of the wheel flange, the two damping rings which are in cantilever shape are fixed by the screws and respectively arranged above and below the wire spokes, a relative position between the two damping rings is defined by the length of the supporting bushing and is fixed by the screws, the friction plates are placed between the damping rings and each wire spoke and are bonded on a beam surface of the wire spoke to form a certain clearance between the damping rings, and the size of the clearance is defined by a vibrational acceleration valve. When vibrating, elastic collision or friction is formed between the friction plates and the damping rings, thereby attenuating vibration generated outside, and performing significant damping effect.
Description
Technical field
The utility model belongs to mechanical vibration and friction techniques field, especially a kind of modified model flywheel body that has vibration-reducing and damping device.
Background technique
Flywheel body is the output mechanism of moment of momentum in the momenttum wheel, so flywheel body generally is designed to high-performance structure in the momenttum wheel, produces bigger rotary inertia with less quality as far as possible, and promptly flywheel mass is little with the ratio of rotary inertia; Flywheel body adopts the former formula mostly---plectane supports wheel rim or spoke-type---, and spoke supports rim construction; Under the conventional situation, former formula or spoke-type flywheel all be the monoblock blank through car, working procedure processing such as mill comes out, and the flywheel body that processes like this is a rigid unitary, without any vibration-reducing and damping device; Therefore, under the same conditions, the disc formula is compared with spoke structure, and the ability of the shock resistance of disc formula, anti-vibration is stronger, but overall weight is bigger than normal; The spoke-type total quality is lighter, but the ability of shock resistance, anti-vibration a little less than.
Summary of the invention
For make flywheel body have simultaneously less matter be used to than with stronger shock resistance, anti-vibration ability, the utility model has improved the flywheel body project organization, it is a kind of modified model flywheel body that has vibration-reducing and damping device, this modified model flywheel body has less matter and is used to ratio, has stronger shock resistance, anti-vibration ability simultaneously again.
In order to realize the foregoing invention purpose, the utility model adopts following technological scheme:
The described modified model flywheel body that has vibration-reducing and damping device is by wheel rim, spoke, screw, friction plate, damping ring, support bushing, bolt, wheel hub constitutes, wherein five I shape spokes by equal angular respectively with the wheel hub welding and with wheel rim be a modified model flywheel body by screw, on ten little convexes being separated by five I shape spokes on the wheel rim inner diameter wall, be fixed with two damping rings, it is cantilever-shaped by screw that damping ring is, fix latter two damping ring lay respectively at spoke on, below, the relative position between two damping rings are determined by the length of support sleeve and by bolt; Friction plate and is adhered on the beam face of spoke between damping ring and each spoke, and forms certain interval between the damping ring, and the size in gap is decided by the vibration acceleration value.
Owing to adopt technological scheme as mentioned above, the utility model produces following good effect:
1, simple in structure, the good manufacturability, easy for installation of flywheel body, stable work in work, reliable;
2, vibration-reducing and damping device makes the shock resistance of flywheel body, anti-vibration ability improve 6～7 times;
3, reduce the flywheel body overall weight greatly;
4, because the outstanding effectiveness in vibration suppression of flywheel body significantly improves the global reliability of momenttum wheel.

Embodiment
As Fig. 1,2,3,4, shown in 5: the modified model flywheel body that has vibration-reducing and damping device of the present utility model is by wheel rim (1), I shape spoke (2), screw (3), friction plate (4), damping ring (5), support bushing (6), bolt (7), wheel hub (8) constitutes, wherein five I shape spokes (2) are fixed as a modified model flywheel body with wheel hub (8) welding and with wheel rim (1) by screw (3) by the equal angular separation, on ten little convexes being separated by five I shape spokes (2) on wheel rim (1) inner diameter wall, be fixed with two damping rings (5), it is cantilever-shaped fixing by screw (3) that two damping rings (5) are, lay respectively at spoke (2) on, below, the relative position between two damping rings (5) are determined by the length of support sleeve (6) and are fixing by bolt (7); Friction plate (4) is positioned between damping ring (5) and each spoke (2), and is adhered on the beam face of spoke (2), and forms certain interval between the damping ring (5), and the size in gap is decided by the vibration acceleration value.
Adopt this modified model flywheel body, being subjected to extraneous power in the vibrative process, form elastic impact or friction between friction plate (4) on the width of cloth bar (2) and the damping ring (5), this elastic impact and friction all will absorb a large amount of vibrational energies, therefore the decay of efficiency ground is by the vibration of extraneous power generation, and its effectiveness in vibration suppression is very outstanding.
