The guide roller is fixed on the guide roller shaft through an upper bearing anng and the lower bearing are symmetrically fixed on idler roller shaft; the outer end surface of the oil seal block of the lower bearing abuts on a lining; a screw for positioning arranged on the upped a lower bearing that are symmetrically arranged. The outer end surface of the oil sealing retainer of the lower bearing press against the bush. By turning the screw arranged on the upper end of the r end of the idler roller shaft is twisted; the spacing between lining and the lower end face of the table shaped face of the upper end of the idler roller shaft can be properly changed; the positioneguide roller shaft to fix the shaft, the distance between the bush and the lower end surface of the shape table on the upper end of the guide roller shaft will be properly changed; the bearing gap betd intervenient gap of the bearing can be changed in company; the adjustment of the bearing gap can ensure that the idler roller is in the normal operating state; the long lifetime of the means can be ween will be changed accordingly. The bearing gap regulating guarantees normal working condition of the guide roller and the bearing so that the service life of the component is prolonged. lengthened.

Description

The adjusting device in the gap of rolling guide deflector roll bearing

Technical field

The utility model discloses labor and materials rolling guide on the milling train in a kind of metallurgy industry, specifically is the lash adjusting device of the deflector roll bearing in the rolling guide.

Background technology

In the prior art, the deflector roll bearing clearance in the rolling guide is objective reality always, and still unmatchful so far bearing clearance therebetween there is no concrete adjustment scheme.Fig. 6 of Chinese patent ZL97211967.1 specification is exactly one of concrete structure, this structure is fixedly mounted on deflector roll 1a on the eccentric shaft 2b by a bearing 19, structure among Fig. 6 shows that the outside spacing of the outer face of deflector roll 1a and bearing 19 fixes, especially eccentric shaft 2b is used for realizing eccentric rotary, therefore, can't adjust two bearings 19 bearing clearance separately with the mode of eccentric rotation axis 2b.

Technology contents

The purpose of this utility model provides a kind of adjusting device of gap of rolling guide deflector roll bearing, makes deflector roll and bearing be in normal duty, prolongs the service life of member.

For achieving the above object, the adjusting device in the gap of rolling guide deflector roll bearing provided by the utility model, it comprises the guide roller axis between the upper and lower cantilever that is fixed on the deflector roll support arm, deflector roll by two symmetrically arranged bearing fixing up and down on guide roller axis, it is characterized in that: the outer face of the oil sealing retaining of described lower bearing is resisted against on the lining, the guide roller axis upper end

The lower surface of shape table top is resisted against on the outer face of oil sealing retaining of upper bearing (metal), and the guide roller axis upper end is provided with the screw that is located.

In technique scheme, turn the guide roller axis upper end and be provided with the screw that is located, be positioned at lining and guide roller axis upper end

Spacing between the lower surface of shape table top will suitably change, therebetween bearing clearance will change thereupon, thereby realized the adjustment of bearing clearance, the adjustment of bearing clearance will guarantee that deflector roll and bearing are in normal duty, and then be very natural the service life that prolongs member.

Summary of drawings

Fig. 1 is a structural representation of the present utility model.

Referring to Fig. 1, lash adjusting device comprises the guide roller axis 80 between the upper and lower cantilever 21,22 that is fixed on deflector roll support arm 20, deflector roll 10 is fixed on the guide roller axis 80 by two symmetrically arranged

bearings

70,60 up and down, the outer face of the oil sealing retaining 61 of described lower bearing 60 is resisted against on the lining 50 guide roller axis 80 upper ends The lower surface 81 of shape table top is resisted against on the outer face of oil sealing retaining 71 of upper bearing (metal) 70, and guide roller axis 80 upper ends are provided with the screw 90 that is located.

Lower cantalever 22 is provided with guide roller axis 80 lower ends and constitutes against the screw 30 that cooperates.

Described guide roller axis 80 lower ends are provided with U-shaped locating hole 82, are fixed with the alignment pin 40 that passes from described locating hole 82 on the lower cantalever 22.This structure can guarantee that guide roller axis 80 is adjusted up and down and can can't not realize owing to the setting of alignment pin 40 when mobile.

Described lining 50 upper ends have an edge 51, and the concave station face of the installing hole upper end on the lower surface at this edge 51 and the lower cantalever 22 constitutes spacing the cooperation.

The utility model is applicable to the occasion that adopts conical surface bearing mostly, the upper surface of lining 50 plays a part base support, screw 30 cooperates with guide roller axis 80 lower ends and plays the supplemental support effect, especially the bearing clearance is big and guide roller axis 80 deadweights are big and when a certain amount of sinking occurring, screw 30 also has positioning action.

Followingly operation principle of the present utility model is described with reference to Fig. 1:

When adjustment screw 90 moves up and down, will compress or loosen the upper end of guide roller axis 80

Be press-fitted the gap between the outer face of the outer face of the lower surface 81 of shape table top and the oil sealing of upper bearing (metal) 70 retaining 71 and the upper surface of lining 50 and the oil sealing retaining 61 of lower bearing 60, thus the adjustment of realization bearing clearance.In addition, being provided with of alignment pin 40 mainly is to make guide roller axis 80 fixing with respect to deflector roll support arm 20, prevent that guide roller axis 80 from rotating with respect to deflector roll support arm 20, drive

screw

30,90 in the time of can avoiding guide roller axis 80 to rotate like this and rotate, otherwise will cause the bearing clearance out of control with respect to deflector roll support arm 20.
