Abstract
The invention belongs to the technical field of machinery equipment and relates to a straightening machine, in particular to a straightening machine small straightening wheel mechanism which comprises a shaft, back bearing covers, a front bearing cover, sleeves, a first tapered roller bearing and a second tapered roller bearing. The first tapered roller bearing and the second tapered roller bearing are arranged at shaft ends in opposite directions. The sleeves are arranged on the first tapered roller bearing and the second tapered roller bearing in a sleeved mode. The first tapered roller bearing and the second tapered roller bearing are separated through protrusions formed by the inner walls of the sleeves, the inner ends of the sleeves are sealed through the back bearing covers, and the back end of the first tapered roller bearing is limited and fixed through the back bearing covers. The straightening machine small straightening wheel mechanism is simple and reasonable in structure, when the mechanism is used, assembling is convenient, bearing axial gaps can be adjusted in time conveniently during using, and the service life of the bearings is effectively prolonged.
Description
Technical field
The invention belongs to mechanical equipment technical field, relate to a kind of arbor press, specifically the little rectification wheel mechanism of a kind of arbor press.
Background technology
It is each a set of that H profile steel wing plate arbor press is generally furnished with size rectification wheel.Little rectification wheel is mainly used in the H profile steel of correcting small dimension.
In the little pressing wheel mechanism of arbor press originally, the adjustment of taper roll bearing axial gap realizes by the mating surface on repair bearing cap, assembles cumbersome.Become greatly owing to using middle (center) bearing gap and not easily adjust, thus accelerate the rate of decay of bearing.
Summary of the invention
The present invention is directed to the problems referred to above, provide a kind of arbor press little rectification wheel mechanism, this mechanism effectively can regulate bearing axial clearance, makes assembling easily, is convenient in use adjust bearing axial clearance in time.
According to technical scheme of the present invention: the little rectification wheel mechanism of a kind of arbor press, is characterized in that: comprise axle, rear bearing cover, front bearing retainer, sleeve and the first taper roll bearing, the second taper roll bearing; Described first taper roll bearing, both the second taper roll bearings are oppositely installed on axle head, jacket casing is located on described first taper roll bearing, the second taper roll bearing, and the projection formed by sleeve lining between the first taper roll bearing and the second taper roll bearing is spaced, sleeve inner end realizes sealing by rear bearing cover, and the first taper roll bearing rear end is spacing fixing by rear bearing cover; Barrel forward end realizes sealing by front bearing retainer, and front bearing retainer has been threaded adjustment screw, and described adjustment screw the inner holds out against on the second taper roll bearing.
As a further improvement on the present invention, described rear bearing cover is supported in sleeve, and is provided with the second sealing ring in rear bearing cover circumferential surface groove, and the second sealing ring is tensioned on sleeve lining.
As a further improvement on the present invention, described front bearing retainer is supported in sleeve, and is provided with the first sealing ring in front bearing retainer circumferential surface groove, and the first sealing ring is tensioned on sleeve lining.
As a further improvement on the present invention, described rear bearing cover is spacing fixing by the shaft shoulder of axle.
Technique effect of the present invention is: product structure advantages of simple of the present invention, and this product in use, assembles convenient, regulates bearing axial clearance in time, effectively extend the service life of bearing in simultaneously easy to use.
Accompanying drawing explanation
