Description
Technical field
Sleeve technical field is the utility model is related to, specially a kind of bearing adapter sleeve.
Background technology
Bearing is a kind of important spare part in contemporary plant equipment.Its major function is the mechanical rotary body of support, is reduced
Coefficient of friction in its motion process, and ensure its rotating accuracy.By the difference of motor element frictional property, bearing can be divided into rolling
Dynamic bearing and the major class of sliding bearing two.Wherein rolling bearing is normalized, seriation, but its radial direction compared with sliding bearing
Size, vibration and noise are larger, and price is also higher.Rolling bearing is typically by outer ring, inner ring, rolling element and the part group of retainer four
Into being strictly speaking made up of outer ring, inner ring, rolling element, retainer, sealing, six big part of lubricating oil.In simple terms, as long as tool
Standby outer ring, inner ring, rolling element just may be defined as rolling bearing.By the shape of rolling element, rolling bearing is divided into ball bearing and roller
The major class of bearing two.In use, can be worn unavoidably between bearing and axle, after long-time use, the internal diameter of bearing and axle it is straight
Footpath mismatches, it may occur that circular runout, the parts on bearing made shift, and influence the stability of plant equipment work, together
When also increase the abrasion of axle, reduce the service life of axle, it is therefore necessary to change the less bearing of internal diameter so that be added to
This, and be typically all in the prior art to add some sleeves for its operation, it is cost-effective to reduce loss, but prior art
In bearing adapter sleeve have the defects of many for example：
1st, it is more troublesome when mounted for bearing adapter sleeve in the prior art, and axostylus axostyle fixed when in use but
It is that protection for bearing then has many deficiencies, because the radius of sleeve also has diminution therewith in fixed axostyle so that axle
Hold has insufficient pressure between sleeve, easily occurs sliding during use and very big load is caused to bearing, accelerate the mill of bearing
Damage degree, so can not meet needed for prior art.
2nd, the connection for sleeve and axostylus axostyle is all in the prior art, and sleeve side is provided with into certain gradient again
Axostylus axostyle is clamped to carry out tightening, such method fish axostylus axostyle that struggles against when mounted is all one section of feelings too many without departing from bearing
Operated under condition, if it is at most difficult to be pressed closer that axostylus axostyle is crossed beyond bearing, so can not meet needed for prior art.
The content of the invention
The purpose of this utility model is to provide a kind of bearing adapter sleeve, asked with solve to propose in above-mentioned background technology
Topic.
To achieve the above object, the utility model provides following technical scheme：A kind of bearing adapter sleeve, including bearing are fixed
Set, thread bush, the fillet of screw and axostylus axostyle fixed cover, the bearing fixing sleeve side are connected with thread bush, thread bush periphery spiral shell
Line is connected with the fillet of screw, and described thread bush one end is connected with spacing collar, and the spacing collar side is connected with axostylus axostyle fixed cover, described
Axostylus axostyle fixed cover periphery is uniformly connected with four clamping screwed holes, and the clamping screwed hole runs through axostylus axostyle fixed cover, the clamping
Screwed hole inside thread is connected with clamping nut, and the bearing fixing sleeve, thread bush, spacing collar and axostylus axostyle fixed cover the same side are all
Offer holding tank.
Preferably, it is connected with antislip metal circle on the outside of the fillet of screw.
Preferably, the axostylus axostyle fixed cover periphery is socketed with position limitation protection circle.
Preferably, the thread bush periphery is circular platform type structure.
Preferably, the clamping nut length is more than clamping screw thread hole length.
Compared with prior art, the beneficial effects of the utility model are as follows：
1st, the utility model is by being connected with thread bush in bearing fixing sleeve side, and thread bush is frustum cone structure, and
And round platform outside screw is connected with the fillet of screw so that its using when bearing fixing sleeve diameter simply can be reduced and put
Greatly, it is easily installed, and thread bush is needed not move through to bearing fixing sleeve diameter control axostylus axostyle to be fixed after installing,
So that pressure between bearing fixing sleeve and bearing is sufficient, then be not in slip can, reduce the abrasion to bearing.
2nd, the utility model is connected with folder by being connected with clamping screwed hole, screwed hole internal thread on the outside of axostylus axostyle fixed cover
Nut is held, the problem of avoiding when axostylus axostyle is long the installation to sleeve so that it is that axostylus axostyle is clamped when in use
While, it is also all overall simply to be expanded, and axostylus axostyle fixed cover and axostylus axostyle fixation are even closer, and secondly bearing is fixed
Set increase relative with the junction pressure of bearing, by being socketed with position limitation protection circle in axostylus axostyle fixed cover periphery, avoid expansion super
Go out deformation quantity.
