Description
Technical field
The utility model belongs to offset press field, relates to the fixing device of offset machine printing roller bearings at both ends, specifically a kind of rotary offset machine otch nut-locking device.
Background technique
In rotary offset machine forme drum bearings at both ends fixing, need to be fixed with nut, and must not run up and have any becoming flexible at forme drum, but because nut is assemblied in the inner narrow space of bearing support, be difficult to add with two round nuts or round nut the in addition tightening of way of lock washer, so need to study a kind of nut that can use in this crawl space of bearing support, can rolling bearing is reliably fixing, in the running up of forme drum, do not have again any loosening.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of simple in structure, ingenious, rational rotary offset machine otch nut-locking device is provided, adopt this device can effectively realize the locking of rotary offset machine forme drum bearings at both ends, realize and in cylinder runs up, do not produce any becoming flexible.
The technological scheme providing according to the utility model: a kind of rotary offset machine otch nut-locking device, comprise roller body, on the described roller body nose circle conical surface, be arranged with roller bearing, roller bearing is locked by locking nut, be characterised in that: between described roller bearing and locking nut inner side end, be provided with packing ring, packing ring holds out against in roller bearing inner ring, on described locking nut, be radially provided with otch, otch extends downward the tapped hole place of locking nut along locking nut circumferential surface, on locking nut, be provided with corresponding to otch place one side the tapped hole extending vertically, socket head screw has been threaded in described tapped hole, and between end face and socket head screw, be provided with spring washer outside locking nut.
As further improvement of the utility model, described roller bearing is placed in bearing support, bearing support is fixed on wallboard by the flange plate of its outer end, in bearing support inner chamber, be also provided with spacer ring, by spacer ring, the outer ring of roller bearing is fixed, described bearing support end face is fastenedly connected end cap by Cock screw, is also arranged with interstage sleeve on roller body.
Compared with prior art, advantage is the utility model: the utility model has solved the fixing difficult problem of rotary offset machine forme drum bearings at both ends, has solved employing conventional nut in the unworkable problem of crawl space.The utility model has effectively been realized in the inner crawl space of bearing adjusting nut easily, realizes the object of locking; In the time of operation, only need to use general utility tool can realize reliable locking simultaneously.The utility model product can not kill for nut, needs to adjust the problem that keeps bearing play, can be adjusted easily locking.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of the locking nut in the utility model.
Embodiment
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
As shown in Figure 1 and Figure 2, comprise roller body 1, bearing support 2, wallboard 3, roller bearing 4, packing ring 5, locking nut 6, otch 7, socket head screw 8, spring washer 9, spacer ring 10, end cap 11, interstage sleeve 12 etc.
As Fig. 1, shown in 2, a kind of rotary offset machine otch nut-locking device of the utility model, comprise roller body 1, on the described roller body 1 nose circle conical surface, be arranged with roller bearing 4, roller bearing 4 is locked by locking nut 6, between described roller bearing 4 and locking nut 6 inner side ends, be provided with packing ring 5, packing ring 5 holds out against in roller bearing 4 inner rings, on described locking nut 6, be radially provided with otch 7, otch 7 extends downward the tapped hole place of locking nut 6 along locking nut 6 circumferential surfaces, on locking nut 6, be provided with corresponding to otch place one side the tapped hole extending vertically, socket head screw 8 has been threaded in described tapped hole, and be provided with spring washer 9 between locking nut 6 outside end faces and socket head screw 8.
Described roller bearing 4 is placed in bearing support 2, bearing support 2 is fixed on wallboard 3 by the flange plate of its outer end, in bearing support 2 inner chambers, be also provided with spacer ring 10, by spacer ring 10, the outer ring of roller bearing 4 is fixed, described bearing support 2 end faces are fastenedly connected end cap 11 by Cock screw, are also arranged with interstage sleeve 12 on roller body 1.
Roller bearing 4 in the utility model adopts conical bore double row cylindrical roller, the inner ring of this bearing is pressed on the conical surface of roller 1, after adjusting bearing play, locking nut 6 is locked on roller 1, realize the locking of locking nut 6 by tightening socket head screw 8, otch 7 both sides are locked at nut on the outside thread of roller 1 tightly because of the change of pitch, socket head screw 8 is due to the effect of spring washer 9 simultaneously, be fixed on tightly on locking nut 6, guarantee in forme drum runs up, can be not former thereby loosening because of machine vibration etc.
