Description
Technical field
The utility model belongs to mechanical fitting technical field, is related to a kind of bearing, more particularly to a kind of automatic aligning biserial
Deep groove ball bearing.
Background technology
Deep groove ball bearing is a type the most common in rolling bearing, and a kind of bearing being most widely used,
Its main feature is that frictional resistance is small, rotating speed is high, can be used to bearing radial load or radial and axial while effect joint load
On parts, deep groove ball bearing is simple in structure, easily reaches the higher accuracy of manufacture compared with other type, and institute is in order into series
Produce in enormous quantities, manufacture cost is relatively low, and wherein biserial deep groove ball bearing is more suitable for applying and is born in a single-groove grooved ball bearing
The Bearing configuration of lotus scarce capacity, in the production of traditional deep groove ball bearing, although with certain self-aligning capability, its axis
The angle of inclination in hole is smaller, i.e., enabled normal work, but has certain influence to the service life of bearing.
The content of the invention
The purpose of this utility model is to be directed to the above-mentioned problems in the prior art, there is provided one kind has automatic aligning
The biserial deep groove ball bearing of function and aligning angle bigger.
The purpose of this utility model can be realized by following technical proposal：A kind of automatic aligning biserial deep groove ball bearing,
It is parallel on the outer wall of the inner ring to offer two row grooves, and two row grooves including the inner ring set and the outer ring of cooperating
Some balls are inside uniformly arranged with, are positioned between the ball by retainer, it is characterised in that the inner wall of the outer ring
On in the correspondence position of each ball offer card slot, and elastic device is arranged with card slot, described elastic device one end is supported
It is against card slot bottom end and is fixed with hemispheric aligning block, the inner wall of the aligning block is fitted closely with ball, the outer ring
Inner wall and aligning block between leave adjust gap.
The technique effect of this automatic aligning biserial deep groove ball bearing is：The main function of deep groove ball bearing is support machinery rotation
Special transmission shaft is turned, but after mounting when the concentricity between bearing and axis is not high or produces mill after long-term use
Damage, axis will apply bearing the power of one inclined radial, and traditional deep groove ball bearing is due to straight by inner ring, outer ring and ball
Poor only 2 '~10 ' left and right of the therefore self-aligning capability that is connected are connect, although can work normally, have impact on bearing uses the longevity
Life, this automatic aligning biserial deep groove ball bearing is by the design of elastic device and aligning block, when relative tilt between bearing and axis
When, it tilts the radial pressure produced and is conducted to ball by inner ring, due to elastic device, will make wherein one row elasticity dress
Another row stretching of extruding is put, is fitted closely between aligning block and ball, therefore can effectively increase its aligning angle automatically.
In a kind of above-mentioned automatic aligning biserial deep groove ball bearing, lubricating grease is perfused between the inner ring and outer ring
And sealing ring is provided at both ends with positioned at it, the sealing ring is elastomeric material.Bearing inner can be reduced by lubricating grease
Friction, increases its service life, and inner ring will produce extruding during aligning to sealing ring side, to prevent lubricating grease stream
Go out, which is elastomeric material.
In a kind of above-mentioned automatic aligning biserial deep groove ball bearing, one end of the inner ring is arranged with dustproof cover, described
Dustproof cover on to be provided with the number of degrees of inclined angle alpha and angle [alpha] be 162 °, the outside diameter of the dustproof cover and the outside diameter size phase of outer ring
Together.The gap that the design of dustproof cover tilt angle can be effectively reduced between dustproof cover and outer ring increases its dust-proof effect.
In a kind of above-mentioned automatic aligning biserial deep groove ball bearing, the elastic device is spring.
Compared with prior art, the matching design that this automatic aligning biserial deep groove ball bearing passes through elastic device and aligning block
The advantages of making it have aligning angle bigger and longer service life.
