Description
Technical field
The utility model is related to circular vibrating screen eccentric shaft fields, and in particular to a kind of circular vibrating screen eccentric shaft.
Background technology
Circular vibrating screen is that one kind doing circular vibration, multilayer number, new high-efficiency vibrating screen.Circular vibrating screen is swashed using barrel-type eccentric shaft
Shake device and inclined block adjusting amplitude, and material sieve drops down line length, and screening specification is more, have structure is reliable, exciting force is strong, screening efficiency is high,
The features such as vibrating noise is small, sturdy and durable, easy to maintenance, safe to use.
Currently, the eccentric shaft axis rank of circular vibrating screen easily rubs with outside framework oil seal in use and generates groove, this leads
Deflection mandrel is damaged, and oil leakage phenomenon is caused, and by wearing for a long time, needs replacing new axis, expense is more expensive.
Utility model content
Above-mentioned in order to solve the problems, such as, the utility model provides a kind of circular vibrating screen eccentric shaft.
The utility model is achieved through the following technical solutions：
A kind of circular vibrating screen eccentric shaft, including circular vibrating screen eccentric shaft body, the circular vibrating screen eccentric shaft body includes first axle
Rank and the second axis rank, the first axle rank is symmetrically arranged at the both sides of circular vibrating screen eccentric shaft body with the second axis rank, described
It is socketed with protective jacket on second axis rank.
Preferably, the first axle rank outboard end is provided with T-slot, described T-slot one end and insertion by arc distribution
Slot connection is simultaneously vertical.
It is further preferred that the outer surface of the second axis rank is equipped with external screw thread, the second axis rank passes through external screw thread
It is spirally connected with locknut, the locknut is tightly bonded with protective jacket side.
It is further preferred that the protective jacket end face is fixed with convex block, the convex block is inserted into embedded groove and is revolved with T-slot
Turn connection.
Still more preferably, the outer surface of the protective jacket is handled by hot-spraying technique, and the case hardness is preferable.
Compared with prior art, the utility model has the beneficial effects that：
1, by being socketed with the protective jacket handled by hot-spraying technique on the second axis rank, prevent outside framework oil seal from shaking with circle
Eccentric shaft body direct friction is sieved, the protective jacket case hardness higher abrasion resistance through Overheating Treatment is higher, and service life is longer, leakage
Oily phenomenon is reduced；
2, the embedded groove of first axle rank is injected by the convex block on protective jacket and is rotated in T-slot, by protective jacket and first
Axis rank is fixed, accordingly even when the locknut for compressing protective jacket loosens, protective jacket can also continue to will not fall off in the second axis rank, more
The second axis rank can be protected by adding, and the reliability that circular vibrating screen eccentric shaft body uses is made to greatly improve.

Specific implementation mode
The utility model is described in further detail with specific implementation mode below in conjunction with the accompanying drawings：
As shown in figs 1 to 6, a kind of circular vibrating screen eccentric shaft, including circular vibrating screen eccentric shaft body 1, the circular vibrating screen eccentric shaft
Ontology 1 includes first axle rank 2 and the second axis rank 3, and it is inclined that the first axle rank 2 with the second axis rank 3 is symmetrically arranged at circular vibrating screen
The both sides of spindle body 1, protective jacket 4 is socketed on the second axis rank 3, and the outer surface of the second axis rank 3 is equipped with outer spiral shell
Line 6, the second axis rank 3 are spirally connected by external screw thread 6 and locknut 5, and the locknut 5 is tightly bonded with 4 side of protective jacket.
2 outboard end of first axle rank is provided with T-slot 2-2, the one end the T-slot 2-2 and insertion by arc distribution
Slot 2-1 connections are simultaneously vertical.
4 end face of the protective jacket is fixed with convex block 4-1, the convex block 4-1 and is inserted into embedded groove 2-1 and is revolved with T-slot 2-2
Turn connection.
The outer surface of the protective jacket 4 is handled by hot-spraying technique, and the case hardness is preferable.
Operation principle：
Circular vibrating screen eccentric shaft body 1 is relatively rotated with outside framework oil seal in use, especially direct with outside framework oil seal
3 serious wear of the second axis rank of contact is prevented by being socketed with the protective jacket 4 handled by hot-spraying technique on the second axis rank 3
Only outside framework oil seal and 1 direct friction of circular vibrating screen eccentric shaft body, the 4 case hardness higher abrasion resistance of protective jacket through Overheating Treatment compared with
Height, service life is longer, and oil leakage phenomenon is reduced, and oil leak is serious, and can unscrewing locknut 5, this directly replaces protective jacket 4, does not have in this way
Change axis, better economy；The embedded groove 2-1 of first axle rank 2 is injected by the convex block 4-1 on protective jacket 4 and is revolved in T-slot 2-2
Turn, protective jacket 4 and first axle rank 2 is fixed, even if the locknut 5 for compressing protective jacket 4 can continue if loosening protective jacket 4
Second axis rank 3 will not fall off, and can more protect the second axis rank, the reliability that circular vibrating screen eccentric shaft body 1 uses is made to carry significantly
It is high.
