Description
Technical field
The utility model relates to mechanical field, particularly a kind of pressure roller be assemblied on stretch bending-straightening machine.
Background technology
Pressure roller is the strength member on stretch bending-straightening machine, and the pressure utilizing one or more groups pressure roller to produce carrys out stretch-bending straightening metal material, the impact of Dynamic And Static Loads when pressure roller mainly bears rolling, wearing and tearing and variations in temperature.At present, existing pressure roller normally connection bearing in its both sides rotating shaft in use, rotated by driven by motor pressure roller, and come to apply pressure to pressure roller by hydraulic cylinder or cylinder, in practical process, bearing larger moment for supporting refined bearing, being easy to be damaged, need often maintenance or change.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides the pressure roller be assemblied on stretch bending-straightening machine that a kind of service time, longer, maintenance time reduced.
The technical solution of the utility model is: a kind of pressure roller be assemblied on stretch bending-straightening machine, comprise roller and the rotating shaft being positioned at roller both sides, it is characterized in that: outside rotating shaft, be arranged with No. two bearing glands, rotating shaft outer ring sleeve is provided with cage ring, in cage ring, cover has taper roll bearing, taper roll bearing is provided with bearing housing by spacer, No. two bearing glands, outside taper roll bearing and bearing housing, a bearing gland is installed, a described bearing gland to kill on taper roll bearing outer ring and is fixed on outside bearing housing by hexagon-headed bolt, namely near roller place, No. three bearing glands are installed inside bearing housing, outside framework oil seal is provided with in No. three bearing glands.
A described bearing gland, No. two bearing glands, No. three bearing glands are used for fixing and protection taper roll bearing.
Described No. two bearing glands, No. three be respectively equipped with sealing ring between bearing gland and bearing housing.
Described cage ring has anti-skidding effect, can avoid producing sliding friction between double-row conical bearing and rotating shaft, protection rotating shaft not impaired service life with extending biserial circular cone roller bearing.
Described taper roll bearing is double-row conical bearing.
Described No. three bearings are provided with aperture, and outside framework oil seal is installed in aperture, and aperture outside framework oil seal gland covers tightly, outside framework oil seal is Double-lip framework oil sealing, can prevent oil seepage, and the secondary lip of Double-lip framework oil sealing plays dustproof effect simultaneously, prevent extraneous dust, impurity etc. enter pressure roller inside.
The beneficial effects of the utility model are: the utility model, by being provided with cage ring between bearing inner race and rotating shaft, can be avoided producing sliding friction between bearing inner race and rotating shaft, thus extend the service life of bearing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1-roller, 2-rotating shaft, 3-bearing gland, 4-No. bis-bearing glands, 5-soket head cap screw, 6-" O " shape sealing ring, 7-hexagon-headed bolt, 8-bearing housing, 9-double-row conical bearing, 10-spacer, 11-No. tri-bearing glands, 12-outside framework oil seal, 13-cage ring, 14-outside framework oil seal gland.
