Description
Technical field
The present invention relates to shock absorbing sealing element technical field, specially a kind of mechanical vibration damping seal.
Background technology
Seal be prevent fluid or solia particle from leak and prevent between adjacent faying face introduced contaminants such as dust with
The material or part of parts inside the intrusion machinery equipment such as moisture.The storage room temperature of seal is kept away preferably below 30 DEG C
Exempt from seal and produce high temperature ageing.
Pressure is to influence a major reason of seal quality first, the height of pressure, pressures cycle mechanical periodicity
Length, have a great impact to seal damage (as extruded).Pressure is higher, and other factors are got over to the performance impact of seal
Greatly, such as temperature, speed, the material of seal, the gap between piston and cylinder barrel, the gap between piston and cylinder head.Secondly
It is that Wellendichtring produces gap between the increase meeting and rotating shaft of usage time, causes seal to do eccentric fortune relative to rotating shaft
It is dynamic, easily cause rotating shaft to produce vibration, severe patient can damage machine and cause the accident.
But some drawbacks in use be present in traditional seal, such as：
1st, traditional Wellendichtring produces certain space, led along with the increase of usage time between seal and rotating shaft
Rotating shaft is caused to produce vibrations, vibrations can aggravate the damage of machinery, and traditional seal does not have the effect of damping, causes plant equipment
Service life reduce.
2nd, traditional Wellendichtring is most difficult to solve the problems, such as be exactly the friction between seal and rotating shaft, this friction
It is and the arch-criminal of mechanical failure the main reason for causing to produce gap between seal and rotating shaft.
The content of the invention
It is an object of the invention to provide a kind of mechanical vibration damping seal, asked with solve to propose in above-mentioned background technology
Topic.
To achieve the above object, the present invention provides following technical scheme：A kind of mechanical vibration damping seal, including rotating shaft, axle
Hold inner ring, bearing outer ring and sealing rubber cover, be uniformly movably installed with steel ball outside the bearing inner race, outside the bearing inner race
Side is rotatably connected to bearing outer ring by steel ball, and the bearing inner race two sides are fixedly welded with set adapter ring, the socket respectively
Circle external stability is socketed with sealing rubber cover, and the sealing rubber cover is provided with first positioned at one end external stability where set adapter ring
Tight loop, the first tight loop middle part are installed with the first tightening buckle；The sealing rubber cover is away from the first tight loop one
Hold fixedly sleeved outside rotating shaft, the sealing rubber cover is provided with the second fastening away from first tight loop one end external stability
Circle, the second tight loop middle part are installed with the second tightening buckle；The bearing inner race is fixed away from steel ball one side center
Surge chamber is provided with, the surge chamber inner homogeneous is installed with buffer spring, and the bearing inner race is located at surge chamber both sides
It is installed with rubber blanket.
Further, the rubber blanket is socketed in outside rotating shaft.
Further, the width of the bearing outer ring is less than the width of bearing inner race.
Further, the sealing rubber cover is manufactured using polymer rubber.
Further, the sealing rubber cover is fixedly mounted on outside rotating shaft by the second tight loop.
Compared with prior art, the beneficial effects of the invention are as follows：
1st, by being internally provided with surge chamber in bearing inner race, buffer spring is installed with inside surge chamber, and delaying
Rush room both sides and be installed with rubber blanket, rotating shaft effectively can be done into the impulsive force that eccentric motion brings and be absorbed, reduced
The severity of rotating shaft vibrations, so as to protect mechanical normal operation, make the service life of machinery more permanent.
2nd, be less than bearing inner race width by set bearing outer ring width, can in order to fixing bearing outer ring, so as to
Seal can be rotated simultaneously with rotating shaft, avoid that friction infringement to caused by machinery occurs between seal and rotating shaft.
