The specific embodiment
Fig. 4 is the schematic diagram of conticaster crystallizer of the present utility model vibration eccentric, Fig. 5 be the B-B of eccentric among Fig. 4 to cutaway view, Fig. 6 is that the C-C of eccentric among Fig. 4 is to cutaway view.Shown in Fig. 4～6, conticaster crystallizer vibration eccentric of the present utility model comprises eccentric shaft 10, eccentric bushing 20, eccentric bushing bearing 30, datum tooth cover 40 and adjusts tooth cover 50, eccentric shaft 10 is installed in fixed position on a pair of fixed bearing block 11,12, described eccentric bushing 20 is enclosed within on the described eccentric shaft 10, and described eccentric bushing bearing 30 is installed on the described eccentric bushing 20; The bearing block 31 of eccentric bushing bearing 30 can be connected by linkage with the vibration frame of conticaster crystallizer.
Described datum tooth cover 40 and adjustment tooth cover 50 are enclosed within on the described eccentric shaft 10, and described adjustment tooth cover 50 carries out circumferentially fixing on described eccentric shaft 10 by flat key 51.One end of described datum tooth cover 40 is provided with a circle rectangular teeth, the other end is provided with a circle stepped tooth, one end of described adjustment tooth cover 50 is provided with a circle stepped tooth, one end of described eccentric bushing 20 is provided with the rectangle teeth groove that the rectangular teeth with described datum tooth cover 40 is complementary, the rectangular teeth of described datum tooth cover 40 is inserted in the rectangle teeth groove of described eccentric bushing 20, the stepped tooth engagement of the stepped tooth of described datum tooth cover 40 and described adjustment tooth cover 50.
Circle shoulder on the end face of described eccentric bushing 20 and the eccentric shaft 10 contact, and described adjustment tooth overlaps 50 and carries out axial restraint by locking nut 60.Locking nut 60 is threaded with eccentric shaft 10.Effect by the circle of one on locking nut 60 and the eccentric shaft 10 shoulder, can will be enclosed within eccentric bushing 20 on the described eccentric shaft 10, datum tooth cover 40 and adjust tooth cover 50 and carry out axial restraint, and the effect by flat key 51, to adjust tooth cover 50 and carry out circumferentially fixing, so just can be so that eccentric bushing 20, datum tooth cover 40 and adjustment tooth cover 50 rotate with eccentric shaft 10 together.
The tooth pitch of the rectangular teeth on the datum tooth cover 40 designs according to fixed amplitude value commonly used, adjustment to normal amplitude, only need unclamp locking nut 60, the rectangular teeth on the datum tooth cover 40 is extracted from the rectangle teeth groove on the eccentric bushing 20, rotating eccentric sleeve 20 gets final product with the relative position of eccentric shaft 10.And in case when needing special amplitude, then can be by regulating the relative position of adjusting tooth cover 50 and datum tooth cover 40 simultaneously, make eccentric adjustment can realize that two-stage regulates, reach various eccentric throw, promptly obtain different amplitudes.The number of teeth of overlapping 40 upper trapezoid teeth by processing adjustment tooth cover 50 and datum tooth can improve the precision of adjusting, and the many more precision of the number of teeth are high more.Under the situation of proof strength and consideration economy, the number of teeth is The more the better.
Conticaster crystallizer vibration eccentric of the present utility model is when using the eccentric throw adjustment always, at first unclamp locking nut 60, eccentric bushing 20 and datum tooth cover 40 are separated, after fixing eccentric bushing 20 with instrument, eccentric rotation axis 10, after needed eccentric throw, again eccentric bushing 20 and datum tooth cover 40 are worked good, screw locking nut 60 again and get final product.
If eccentric throw can be regulated according to the size of departure because the center line processing of eccentric bushing 20 and eccentric shaft 10 is after deviation is arranged.At first unclamp locking nut 60, to adjust tooth cover 50 and datum tooth cover 40 again unclamps to remove and cooperates, according to the machining deviation amount of measuring, overlap 40 certain angles according to suitable direction rotation datum tooth, it is one or several number of teeth, to adjust tooth cover 50 and datum tooth cover 40 then and work good, and tighten screw 52, and screw locking nut 60 again and get final product.So just realized the center line debugging functions of eccentric bushing 20 and eccentric shaft 10, made actual eccentric throw reach higher precision.
When eccentric bushing 20 and eccentric shaft 10 owing to regulate frequent back and wear and tear, make actual vibratory output (being double eccentric throw) when diminishing, the departure that these wearing and tearing cause also can be regulated the relative position of adjusting tooth cover 50 and datum tooth cover 40 according to the method described above, departure to wearing and tearing is revised, realized integrated abrasion compensation, prolong the service life of eccentric, saved the time that the eccentric integral replacing is spent.
Equally, when the new amplitude of technological requirement, also can regulate the relative position of adjusting tooth cover 50 and datum tooth cover 40 according to the method described above, can arrive and be different from conventional amplitude, to satisfy the different process requirement.
