Description
Technical field
The present invention relates to a kind of bearings, and in particular to a kind of with the high speed roller bearing for reducing noise.
Background technique
In shafting structure, rolling bearing due to the advantages that own frictional drag is small, transmission efficiency is high, compact-sized,
It is widely used in modern industry, is the critical component in rotating machinery, while being also the main original for causing shafting vibration and noise
Cause.
The percent ripple of bearing noise main source bearing surface, surface waviness be " it is more much bigger than roughness by spacing,
The surface irregularity that random or close to periodic formation ingredient is constituted.By defining as it can be seen that surface waviness is exactly between microcosmic
Geometry unevenness, surface roughness and macroscopical geometry unevenness, morphology, straightness, circularity, the table between flatness
Face geometry unevenness, it is mainly generated in mechanical processing process by reasons such as lathe-workpiece-tooling system vibrations
's.For bearing under the effect of purely axial power, inside and outside channel surface percent ripple is affected to its hemodynamic characteristics, makes these
Parameter is in cyclic fluctuation, and ripple degree influences retainer center of mass motion track, is increased with ripple degree, retainer mass center
Whirling motion becomes violent；It will increase the vibration of shafting thus to generate noise；
Very noisy and vibration also will affect the service life of mechanical equipment, instrument be damaged, so that certain instruments, instrument, control
Control equipment failure.Experimental study shows when noise level is more than 150dB, understands the elements such as badly damaged resistance, capacitor, transistor.
When extra-heavy noise contributions are when the mechanical structures such as rocket, spacecraft, 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 operator's health, a variety of diseases are induced；To safety in production and working efficiency
The influence of generation.It thus reduces noise to have important practical significance, based on the above, Publication No. JP Tetsukai
2008249128A, publication date are a kind of high speed roller bearing with reduction noise on October 16th, 2008, and specifically disclose
Following content: bearing outer ring, bearing inner race, multiple 0 shape circles and multiple balls, bearing outer-ring, bearing inner race and 0 shape circle are annular
Body, but without disclosing multiple energy consumption friction members 4 in documents, the side wall of energy consumption friction member 4 is machined with gap 6, consumes energy
Friction member 4 is the part that consumes energy made of shape memory alloy material, and the gap 6 on 4 side wall of friction energy-dissipating part increases friction energy-dissipating
The elasticity of element, marmem restore elastic strain rate with good, can achieve 8% or more, to make to rub
Energy consumption part 4 keeps well contacting with the first surface 7 of annular groove 3-1 and second surface 8, and after marmem abrasion
It can use recovery elastic strain and compensate the abrasion that rubs, there are also do not hurt antithesis, the good advantage of wearability for marmem.
Summary of the invention
The content of present invention be in order to solve that O-ring noise reduction in the prior art leans on be material internal damping effect, be by
Dynamic reduction vibration, O-ring noise reduction can only reduce the noise of low frequency, bearing noise smaller for the inhibitory effect of high-frequency noise
It will affect the service life of mechanical equipment with vibration, damage instrument, make instrument, instrument, control equipment malfunction, it can badly damaged electricity
The elements such as resistance, capacitor, transistor.When generating acoustic fatigue, material can be made to generate fatigue phenomenon and be broken.Noise can also be to operator
Member's health generates harm, induces a variety of diseases；The problem of influencing production and working efficiency.And then it provides a kind of with reduction noise
High speed roller bearing.
The present invention in order to solve the above problem and the technical solution adopted is that:
A kind of high speed roller bearing with reduction noise: it includes bearing outer ring, bearing inner race, axle journal, friction energy-dissipating
Part and multiple balls, bearing outer ring, bearing inner race and friction energy-dissipating part are annular body, and the outer diameter of friction energy-dissipating part is D, friction
The side wall of energy consumption part is machined with gap, and axle journal is cylindrical body, and one end of axle journal is machined with boss, and in the axial direction along cylindrical body
It is machined with through-hole, the center line of through-hole is overlapped with the axis of cylindrical body, and one end close to bearing inner race inner sidewall is machined with annular
Groove, bearing outer ring are sleeved on bearing inner race, and multiple balls are uniformly embedded between bearing outer ring and bearing inner race, friction
The part that consumes energy is arranged in annular groove, and the depth of the first surface of annular groove is W, and the numerical value of D is greater than W, and the of annular groove
The width on two surfaces is B, and the numerical value of W is greater than B, and one end that axle journal is machined with boss is inserted on the inner wall of bearing inner race.
The beneficial effects of the present invention are:
1, friction dampers 4 of the present invention are made of marmem, and the internal diameter of friction dampers 4 is less than
The diameter of axle journal 5, the outer diameter of friction dampers 4 are the width W and second of first surface 7 of the D numerical value greater than annular groove 3-1
The width B on surface 8 is installed rear friction dampers 4 in this way and is just compressed in by between 3 slot of axle journal 5 and bearing inner race
In space, the outer surface of friction dampers 4 just respectively with the first surface 7 of annular groove 3-1 and second surface 8 and axle journal
The outer circle face contact of 5 convex platform 5-1, when bearing generate vibration when and 5 convex platform 5-1 of axle journal periphery and first surface 7 and
Second surface 8 generates a part of vibrational energy of frictional dissipation, to reach the vibration and noise for reducing bearing.
2, the present invention is quasi- starts with from vibration source, is fundamentally reduced by reducing the vibrational energy that vibration source propagates out
The generation of noise.The method for hindering vibrational energy to propagate has vibration isolation, structure to inhale battle array and damping vibration attenuation method, and the present invention proposes
A kind of rolling bearing denoising structure, the rolling bearing denoising structure can reduce the vibration of bearing, inhibit noise to generate, hinder to make an uproar
Acoustic propagation, excellent noise reduction effect are easily installed, and do not change bearing main body shape, and promotion and implementation are easy.And then realize reduction noise
Effect, and then the service life of prolonged mechanical equipment guarantee to make instrument, instrument, the normal use for controlling equipment, make resistance, electricity
The safe handling of the original parts such as appearance, transistor prevents occurring the generation that acoustic fatigue causes material to produce fracture phenomenon due to noise, leads to
The health that high speed roller bearing of the invention guarantees operator is crossed, guarantees that equipment can carry out safety in production and normal fortune
Row, and then improve working efficiency.
