Abstract
The utility model discloses a cylinder supporter for a lithographic press, which comprises a cylinder, inner and outer bearings and inner and outer eccentric sleeves, and is characterized in that the inner and outer bearings are hollow roller bearings, centre lanes and outer lanes of the inner and outer bearings are eccentric structures, the outer lanes are provided with regulating masses with tines, the regulating masses engage with adjuster pinions, and end faces of the centre lanes are provided with clutch pressure pin shafts. Because the utility model adopts the hollow roller bearings, the centre and outer lanes of the bearings are the eccentric structures, the bearings drive without gaps, compared with existing techniques, the utility model has the advantage of high accuracy of central distance of the cylinder.
Description
(1) technical field: the utility model belongs to printing machinery, and particularly a kind of cylinder of lithographic press supports.
(2) background technology: the blanket cylinder of lithographic press be supported with two kinds on sliding support and rolling bearing, its structure is that two eccentric bushings support, outer eccentric bushing is used for adjusting centre of the drum's distance, interior eccentric bushing is used for realizing cylinder tripping combined pressure; The gap of this slip and rolling bearing is bigger, be difficult to eliminate, and sliding bearing abrasion is fast, thereby this drum support structure has seriously restricted the raising of China's lithographic press quality.
(3) summary of the invention: the utility model technical issues that need to address are that a kind of cylinder that does not have the rolling bearing gap of design supports.The technical solution of the utility model is, the cylinder of lithographic press supports, comprise cylinder, interior outer bearing and inside and outside eccentric bushing, it is characterized in that: interior outer bearing is a hollow roller bearing, the centre circle of bearing and outer ring are eccentric structure, the outer ring is provided with toothed adjustment piece and is meshed with adjusting gear, and the end face of centre circle is provided with clutch pad axle.The utility model is owing to adopted hollow roller bearing, and bearing does not have the gap, thereby compared with the prior art, has centre-to-centre spacing advantage of high precision between cylinder.
(4) description of drawings: Fig. 1 is a structural representation of the present utility model, and Fig. 2 is the left view of Fig. 1.1. support wallboard 2. preceding gland 3. cylinders 4. bearing inner races 5. bearing centre circles 6. clutch pad axles 7. bearing outer rings 8. pressure regulation pieces 9. hollow rollers 10. rear pressing covers among the figure.
(5) specific embodiment: the utility model comprises cylinder 3, two roller bearings place between bearing inner race 4 and the bearing centre circle 5 respectively and between bearing centre circle 5 and the bearing outer ring 7, this roller bearing adopts hollow roller 9, bearing centre circle 5 and bearing outer ring 7 are eccentric structure, and its offset is determined according to the tripping combined pressure amount of centre distance between cylinder and cylinder.With preceding gland 2, rear pressing cover 10 and bolt bearing group is integrated, blanket cylinder places bearing inner race 4, the outer face of bearing centre circle is provided with clutch pad axle 6, the pressure regulation piece 8 that is provided with a sector on the outer surface of bearing outer ring 7 is meshed with the pressure regulation gear, the cylinder that combines is supported and fixed on supports on the wallboard 1.It transfers the method for centre-to-centre spacing to be, changes an angle by rotating pressure regulation gear driven pressure regulation piece, drives the roller shifting certain distance.When needing the tripping combined pressure, handle clutch pad axle 6 and make the bearing centre circle move an angle, roller shifting, the tripping combined pressure of realization cylinder.
Claims (1)
1. the cylinder of lithographic press supports, comprise cylinder, interior outer bearing and inside and outside eccentric bushing, it is characterized in that: interior outer bearing is a hollow roller bearing, the centre circle of bearing and outer ring are eccentric structure, the outer ring is provided with toothed adjustment piece and is meshed with adjusting gear, and the end face of centre circle is provided with clutch pad axle.
