Description
Technical field
The present invention relates to a kind of flywheels, and in particular to a kind of flywheel with denoising structure belongs to mechanical transmission fields.
Background technology
In shafting structure, rolling bearing due to own frictional drag is small, transmission efficiency, it is compact-sized the advantages that,
Be widely used in modern industry, be the critical component in rotating machinery, at the same be also cause flywheel vibration and noise it is main
Reason.It is mainly manifested in the following aspects：First, the percent ripple of bearing surface, surface waviness are bigger than roughness by spacing
Much, surface irregularity that random or close to periodic formation ingredient is formed.By defining as it can be seen that surface waviness is exactly to be situated between
In microcosmic geometry unevenness, surface roughness and macroscopical geometry unevenness, morphology, straightness, circularity, flatness it
Between surface geometry unevenness, it mainly in mechanical processing process by reasons such as the vibrations of lathe-workpiece-tooling system
It generates.Research shows that bearing, under the effect of purely axial power, inside and outside channel surface percent ripple is to its hemodynamic characteristics shadow
Sound is larger, makes these parameters in cyclic fluctuation, and the ripple number of degrees influence retainer center of mass motion track, increase with the ripple number of degrees
Add, retainer barycenter whirling motion becomes violent；Thus it can increase the vibration of shafting so as to generate noise；2nd, bearing ball is inside and outside
The shock loading that collision between circle generates, due to the form error of ball manufacture and the influence of bearing surface percent ripple, axis
Ball in the process of running is held inevitably to collide with bearing inner race, outer ring and retainer, flywheel by axle journal and
Bearing inner race is connected, thus these shock loadings can be acted on flywheel so as to cause the vibration of flywheel, and then cause noise.
Very noisy can influence the service life of mechanical equipment with vibration, damage instrument so that certain instruments, instrument, control
Equipment malfunction.Experimental study shows, when noise level is more than 150dB, the elements such as badly damaged resistance, capacitance, transistor.When
For extra-heavy noise contributions when rocket, spacecraft are when mechanical structures, due to the repeated action by audio frequency cycling alternating load, generation sound is tired
Labor can make material generate fatigue phenomenon and be broken.In addition, noise can also generate harm to user of service's health, induce more
Kind disease, has an impact safety in production and working efficiency.
Invention content
The very noisy generated when the present invention is solves flywheel turns and vibration effect mechanical equipment service life, damage instrument
Device leads to the problem of user of service's health and endangers, and then proposes a kind of flywheel with denoising structure.
The present invention adopts the technical scheme that in order to solve the above problem：The present invention is made of wheel hub, spoke and wheel rim, this hair
Bright to further include multiple marmem blocks, the both sides of wheel rim are along the circumferential direction uniformly provided with multiple grooves, divide in each groove
It An Zhuan not a marmem block.
Further, each marmem block is mounted on by screw in groove.
Further, each screw is Self-locking screw.
Further, each groove is rectangular recess, and each marmem block is rectangular blocks, described
The middle part of rectangular blocks side side is equipped with the first surface of indent, and the middle part of the rectangular blocks opposite side side is equipped with
Second curved surface of indent.
Further, the both sides of first surface are equipped with the first plane, and the both sides of the second curved surface are equipped with the second plane, two the
One plane is contacted with the side side wall in groove, and two the second planes are contacted with the opposite side side wall in groove.
Further, the both ends of each marmem block are all provided with jagged.
The beneficial effects of the invention are as follows：1st, the vibration of flywheel can be reduced, noise is inhibited to generate, hinders noise transmission, noise reduction
Effect is good, is easily installed, and does not change flywheel body shape, and promotion and implementation are easy；2nd, the present invention starts with from vibration source, by subtracting
The amplitude in small vibration source is so as to fundamentally reduce noise；3rd, the present invention is lost by the friction energy-dissipating method in damping shock absorption
A part of vibrational energy, so as to achieve the purpose that damping noise reduction；4th, existing noise reduction flywheel is mostly using viscoelastic material, viscoplasticity
Material has larger damping capacity, but its damping capacity is influenced by a variety of environment such as temperature, is susceptible to aging, and after aging
Damping capacity drastically declines, thus needs regularly to carry out material maintenance, and cost is higher and time-consuming, and the present invention is remembered using shape
Recall alloy damping by friction noise reduction, do not limited by environmental factors such as temperature, and marmem restores flexible deformation rate
It can reach 8% even higher, thus the shape memory alloy elastic under compressive state is fine, and by that can restore after wearing
Flexible deformation reaches the contact condition before abrasion；5th, marmem block of the invention has preferable elasticity, and wears
Have the function of to compensate automatically afterwards, and marmem has good wearability, when friction does not hinder the formedness of antithesis
Energy.
