The sphere automatic leveling device has the beneficial effects that the principle of the force on the sphere surface going through the sphere center is utilized, so the force generated in different directions can go through the sphere center, the force on the bearing is uniform in the press fitting process and the abrasion of the bearing is reduced, and in addition, the fine adjustment is realized, the structure is simple, and the operation is convenient.
Description
Technical field
The utility model relates to a kind of bearing servicing unit, especially relates to a kind of sphere self-level(l)ing device.
Background technology
At present, carry out tension and compression tests or in the process that bearing press-fits at puller system, because there is error in the perpendicularity of axle and the shaft shoulder, and axle is in the error of perpendicularity of workbench anchor clamps and work top fixedly the time, and equipment center and had error by the axiality in tension and compression part axle center, cause bearing axiality of pressure head and axle in installation to have angle, in press-fiting process because discontinuity, easily produce deviation phenomenon, cause bearing, the mating surface of axle or the shaft shoulder damages, so that bearing rotates dumb (retainer is impaired), finally cause inordinate wear between bearing roller or retainer and the Internal and external cycle, accelerate scrapping of bearing.
Chinese patent Granted publication number: CN 201799997U, Granted publication day is on April 20th, 2011, a kind of bearing press is disclosed, comprise brace table, support, push rod and fixture, support is fixed on the upper surface of brace table, push rod is arranged on the support, fixture is arranged on the brace table, described push rod comprises screw mandrel and handle, described handle is fixed on the upper end of screw mandrel, be provided with the feed screw nut on the described support, screw mandrel cooperates with the feed screw nut, and described push rod lower end is provided with pressure head.The weak point of this utility model is, there is angle in bearing axiality of pressure head and axle in installation, because discontinuity easily produces deviation phenomenon, finally causes the bearing inordinate wear in press-fiting process, accelerates scrapping of bearing.
The utility model content
The utility model is in order to overcome the prior art middle (center) bearing in press-fiting engineering because the problem that discontinuity easily causes the bearing inordinate wear and scraps provides a kind of bearing stressed sphere self-level(l)ing device that relatively evenly reduces bearing wear in press-fiting engineering.
To achieve these goals, the utility model is by the following technical solutions:
A kind of sphere self-level(l)ing device of the present utility model, comprise ball watt base and bulb bearing, a described ball watt base comprises base, described base is provided with ball recess, described bulb bearing comprises bearing, described bearing is provided with the hemisphere jut corresponding with ball recess, and the radius of described hemisphere jut is consistent with the radius of ball recess.
A described ball watt base comprises base, described base is provided with ball recess, described bulb bearing comprises bearing, described bearing is provided with the hemisphere jut corresponding with ball recess, described bulb bearing places the ball recess of ball watt base by hemisphere jut, utilize the stressed principle by the centre of sphere of sphere, can be so that the power that produces be in different directions passed through the centre of sphere, avoid the positioning fixture of other shapes to produce side force and cause pressure head and be pressed into the axle decentraction, perhaps make anchor clamps yielding.The radius of described hemisphere jut is consistent with the radius of ball recess, so that sphere-contact is offset side force, and increases contact area.Thereby bearing stressed requirement that relatively evenly reduces bearing wear in press-fiting engineering has been satisfied in design like this.
As preferably, the height of described hemisphere jut is greater than the degree of depth of ball recess, and the difference in height of hemisphere jut and ball recess has determined adjustable range, can determine according to the error of perpendicularity in the reality processing size of adjusting range.Design is convenient to bearing realizes the automatic fine adjustment in the process that is pressed into like this.
As preferably, the bearing of described bulb bearing is cylindrical, and the hemisphere jut stress equalization is convenient in design like this, is convenient to the automatic leveling in the bearing press mounting.
As preferably, the base of described ball watt base is cylindrical, and the hemisphere jut stress equalization is convenient in design like this, is convenient to the automatic leveling in the bearing press mounting.
As preferably, the upper surface of support of described bulb bearing is provided with at least one T-slot, not only is convenient to the I﹠M of this device, and is convenient to the fixing of bulb bearing.
As preferably, described T-slot is one, and described T-slot is by the upper surface of support center of circle of bulb bearing, and design can be saved manufacture craft like this.
The beneficial effects of the utility model are: utilize the stressed principle by the centre of sphere of sphere, can be so that the power that produces be in different directions passed through the centre of sphere, and then bearing is stressed relatively even in press-fiting engineering, the wearing and tearing of bearing have been reduced, and can realize the automatic fine adjustment, simple in structure, easy to operate.
Description of drawings
