Description
Technical field
The present invention relates to a kind of bearing, be specifically related to a kind of with the high speed roller bearing reducing noise.
Background technology
In shafting structure, rolling bearing due to advantages such as own frictional drag is little, transmission efficiency is high, compact conformations,
Modern industry is widely used, is the critical component in rotating machinery, be also simultaneously cause shafting vibration and noise the most former
Cause.
The percent ripple of bearing noise main source bearing surface, surface waviness be " much bigger by gap ratio roughness,
The surface irregularity that random or close to periodic formation composition is constituted.From definition, surface waviness is exactly between microcosmic
Geometry unevenness, surface roughness and macroscopic view geometry unevenness, the table between morphology, linearity, circularity, flatness
Face geometry unevenness, it is mainly in mechanical processing process by reason generations such as the vibrations of Machinetool workpiece tooling system
's.Bearing is under purely axial power effect, and inside and outside channel surface percent ripple is relatively big on the impact of its hemodynamic characteristics, makes these
Parameter is cyclic fluctuation, and the ripple number of degrees affect retainer center of mass motion track, increases with the ripple number of degrees, retainer barycenter
Whirling motion becomes violent；Thus the vibration of axle system can be increased thus produce noise；
Very noisy also can affect the service life of plant equipment with vibration, damages instrument so that some instrument, instrument, control
Control equipment is malfunctioning.Experimentation shows, when noise level is more than 150dB, understands the elements such as badly damaged resistance, electric capacity, transistor.
When extra-heavy noise contributions is in the frame for movement such as rocket, spacecraft, due to the repeated action by audio frequency cycling alternating load, generation sound is tired
Labor, can make material produce fatigue phenomenon and rupture.
Additionally, noise also can produce harm to operator's health, induce multiple disease；To safety in production and work efficiency
The impact produced.Thus reduce noise and have important practical significance.
Summary of the invention
Present invention is to affect the service life of plant equipment to solve prior art middle (center) bearing noise and vibration,
Damage instrument, make the elements such as instrument, instrument, control equipment malfunction, meeting badly damaged resistance, electric capacity, transistor.When generation sound is tired
Labor, can make material produce fatigue phenomenon and rupture.Noise also can produce harm to operator's health, induces multiple disease；Shadow
Ring and produce and the problem of work efficiency, and then provide a kind of with the high speed roller bearing reducing noise.
The present invention solves that the problems referred to above the technical scheme is that
A kind of with the high speed roller bearing reducing noise: it includes bearing outer ring, bearing inner race, axle journal, friction energy-dissipating
Part and multiple ball, bearing outer ring, bearing inner race and friction energy-dissipating part are annular body, and the external diameter of friction energy-dissipating part is D, friction
The sidewall of power consumption part is machined with gap, and axle journal is cylinder, and one end of axle journal is machined with boss, and along cylinder in the axial direction
It is machined with through hole, the centrage of through hole and cylindrical dead in line, it is machined with annular near one end of bearing inner race medial wall
Groove, bearing outer ring is sleeved on bearing inner race, and uniform between bearing outer ring and bearing inner race is embedded with multiple ball, friction
Power consumption part is arranged in annular groove, the degree of depth of the first surface of annular groove be the numerical value of W, D more than W, the of annular groove
The width on two surfaces is that the numerical value of B, W is more than B, and axle journal is machined with one end of boss and is inserted on the inwall of bearing inner race.
The invention has the beneficial effects as follows:
1, friction dampers 4 of the present invention is made up of marmem, and the internal diameter of friction dampers 4 is less than
The diameter of axle journal 5, the external diameter of friction dampers 4 is the width W and second of the D numerical value first surface 7 more than annular groove 3-1
The width B on surface 8, after such installation, friction dampers 4 is just compressed in by between axle journal 5 and bearing inner race 3 groove
In space, the outer surface of friction dampers 4 the most respectively with the first surface 7 of annular groove 3-1 and second surface 8 and axle journal
The periphery contact of 5 convex platform 5-1, when bearing produces vibration, and the periphery of axle journal 5 convex platform 5-1 and first surface 7 and
Second surface 8 produces a part of vibrational energy of frictional dissipation, thus reduces vibration and the noise of bearing.
2, the present invention intends starting with from vibration source, fundamentally reduces by reducing the vibrational energy that propagates out of vibration source
The generation of noise.The method hindering vibrational energy to propagate has isolating technique, structure to inhale battle array and damping vibration attenuation method, and the present invention proposes
A kind of rolling bearing denoising structure, this rolling bearing denoising structure can reduce the vibration of bearing, and suppression noise produces, and obstruction is made an uproar
Acoustic propagation, excellent noise reduction effect, it is easy to installing, do not change bearing main body shape, promotion and implementation are easy.And then realize reducing noise
Effect, and then the service life of prolonged mechanical equipment, it is ensured that make the normal use of instrument, instrument, control equipment, make resistance, electricity
The safe handling of the original papers such as appearance, transistor, prevents owing to noise occurs that acoustic fatigue causes material to produce the generation of phenomenon of rupture, logical
The high speed roller bearing crossing the present invention ensures that operator's is healthy, it is ensured that equipment can carry out safety in production and normal fortune
OK, so improve work efficiency.
