According to design provided by the present invention, dampening vibrator roller is made up of axle and cylinder, it is characterized in that: axle has left end shaft and right-hand member axle, right-hand member in left end shaft is provided with left flange, left end at the right-hand member axle is provided with right flange, the two ends of cylinder connect end cap respectively, and left flange is connected with two end caps respectively with right flange.
Left end shaft is installed in the front-end bearing pedestal, at the end of left end shaft cover bearing inner ring, between bearing inner race and front-end bearing pedestal needle bearing is set.Left flange is stretched out in the end of left end shaft, and right flange is stretched out in the end of right-hand member axle, forms positioning section respectively, on end cap, be provided with can with the axis hole that allows positioning section to insert and be connected with positioning section.The passage that is communicated with needle bearing is set in the front-end bearing pedestal, and joint is set at the outlet position of passage.Gland is installed in end in left end shaft, and the external diameter of this gland is installed cover plate greater than the internal diameter of bearing inner race at the left end of front-end bearing pedestal.
The right-hand member axle is installed in the rear bearing block, in the end of right-hand member axle bearing inner race is arranged, and between bearing inner race and rear bearing block needle bearing is set.The passage that is communicated with needle bearing, the outlet position erection joint of passage are set in rear bearing block.The end of right-hand member axle is connected with worm-and-wheel gear after passing rear bearing block.At the left end of right-hand member axle and the connecting portion of rear bearing block sealing ring is set.
Whole dampening vibrator roller is divided into three sections, utilizes flange that it is mutually permanently connected together again, installation and removal are all more convenient in printing element; The left end shaft of dampening vibrator roller and right-hand member axle utilize needle bearing to be installed in front-end bearing pedestal and the rear bearing block respectively, and right-hand member axle afterbody is connected with worm-and-wheel gear, when running up, have the axial motion performance of good stable.
Description of drawings
Fig. 1 is original dampening vibrator roller structure chart.
Fig. 2 is a dampening vibrator roller structure chart of the present utility model.
The specific embodiment
As shown in Figure 2: flange type dampening vibrator roller is made up of axle and cylinder 13, axle wherein has left end shaft 24 and right-hand member axle 25, right-hand member in left end shaft 24 is provided with left flange 12, left end at right-hand member axle 25 is provided with right flange 14, the two ends of cylinder 13 connect end cap 32 respectively, and left flange 12 is connected with two end caps 32 respectively with right flange 14.Because original all-in-one-piece dampening vibrator roller is divided into three parts, link together with bolting again, therefore, all convenient especially when processing and manufacturing and installation and maintenance, the defective that can carry out after having avoided original dampening vibrator roller need remove wallboard 26 when maintenance has been guaranteed the installation accuracy of dampening vibrator roller.When needing repairing dampening vibrator roller, the bolt 15 of adpting flange and end cap is laid down, just can like a cork dampening vibrator roller be taken off from wallboard 26.
For guaranteeing the installation accuracy of left end shaft 24, right-hand member axle 25 and cylinder, left flange 12 should be stretched out in the end of left end shaft 24, right flange 14 also should be stretched out in the end of same right-hand member axle 25, to form positioning section 27 respectively, the axis hole 28 that can allow positioning section 27 insertions and be connected with positioning section 27 is set on end cap 32 again, utilize the precision-fit of positioning section 27 and axis hole 28, guarantee positioning accuracy between the two.
The passage 31 that is communicated with needle bearing 2 is set in the front-end bearing pedestal 1, and at the outlet position of passage 31 joint 11 is set, joint 11 is connected with oil pipe, and lubricating oil is introduced in the passage 31, and needle bearing 2 parts such as grade are cooled off with lubricated.
Gland 10 is installed in end in left end shaft 24, and the external diameter of this gland 10 is greater than the internal diameter of bearing inner race 6, in order to avoid bearing inner race 6 breaks away from left end shaft 24, at the left end of front-end bearing pedestal 1 cover plate 7 is installed, in order to avoid dust etc. enter, influences the normal operation of left end shaft 24.
Right-hand member axle 25 is installed in the rear bearing block 17, in the end of right-hand member axle 25 bearing inner race 20 is arranged, and between bearing inner race 20 and rear bearing block 17 needle bearing 18 is set.Utilize needle bearing 18 that right-hand member axle 25 is installed in the rear bearing block 17, its rotating property is greatly improved, guaranteed the operational reliability of dampening vibrator roller.
The passage 31 that is communicated with needle bearing 18, the outlet position erection joint 11 of passage 31 are set in rear bearing block 17.Joint 11 is connected with oil pipe, and lubricating oil is introduced in the passage 31, and needle bearing 18 parts such as grade are cooled off with lubricated.
The end of right-hand member axle 25 is passed rear bearing block 17 backs and is connected with worm-and-wheel gear.At the left end of right-hand member axle 25 and the connecting portion of rear bearing block 17 sealing ring 23 is set, in order to avoid dust enters in the sliding pair.
Among the figure 3,8 is screw, and 4,19,21 is spacer ring, and 5,22 are the hole back-up ring, and 9 is packing ring, and 16 is sealing ring.
