Description

A kind of bar is remained silent the novel bearing box seal device of vertical mill

Technical field

The utility model belongs to rolling bar equipment technical field, relates to a kind of bar and to remain silent the novel bearing box seal device of vertical mill.

Background technique

Bearing box for rolling mill gland of remaining silent during usual Bar Plant rolling is thick is plane, the bearing housing of this vertical mill of remaining silent is for the two ends of horizontal mill, the drive end of vertical mill, all more stable, but, roughing region fine-powdered iron scale is more, vertical milling train Partner (below) Seal in Bearing Box weak effect of remaining silent, fine-powdered iron scale very easily enters bearing housing under the impact of current and the roll of rotation drive, thus the accident of vertical mill Partner burn bearing of remaining silent happens occasionally, during burn bearing, roll changing time is long, operating rate of rolling mill is low, and the spare parts consumption such as roll and bearing means is large, cost of production is increased.

Model utility content

In order to overcome the above-mentioned shortcoming of prior art, the utility model provides one can stop to cause burn bearing because bearing housing enters iron scale, improves operating rate of rolling mill, reduces the consumption of roll and bearing, obtains significant economic benefit bar is remained silent the novel bearing box seal device of vertical mill.

The utility model solves the technological scheme that its technical problem adopts: a kind of bar is remained silent the novel bearing box seal device of vertical mill, comprise the bearing housing being positioned at roll end face, and bearing housing is provided with sphericbearing box end cap, is provided with labyrinth ring between this bearing housing and roll, is respectively arranged with a conical surface baffle ring at labyrinth ring two ends.

Described labyrinth ring dress roller is provided with O type back-up ring, thus avoids iron scale to be deposited in around bearing housing.

The beneficial effects of the utility model are: can not enter in the good bearing housing of sealing effect when iron scale exists; thus protection lubricant grease is not contaminated, reduces the generation of burn bearing accident, improve operating rate of rolling mill; reduce the consumption of roll and bearing, obtain significant economic benefit.

1-roll, 2-labyrinth ring, 3-bearing box end cap, 4-bearing housing, 5-conical surface baffle ring.

Embodiment

Below in conjunction with drawings and Examples, the utility model is further illustrated.

See Fig. 3 and Fig. 5, a kind of bar is remained silent Novel bearing box 4 seal arrangement of vertical mill, comprise the bearing housing 4 being positioned at roll 1 end face, and bearing housing 4 is provided with sphericbearing box end cap 3, is provided with labyrinth ring 2 between this bearing housing 4 and roll 1, is respectively arranged with a conical surface baffle ring 5 at labyrinth ring 2 two ends.

Be provided with O type back-up ring when described labyrinth ring 2 fills roller, thus avoid iron scale to be deposited in around bearing housing 4.

Can not enter when iron scale exists in the good bearing housing 4 of sealing effect, thus protection lubricant grease is not contaminated, reduces the generation of burn bearing accident, improve operating rate of rolling mill, reduce the consumption of roll 1 and bearing, obtain significant economic benefit.

Claims

1. a bar is remained silent the novel bearing box seal device of vertical mill, it is characterized in that: comprise the bearing housing being positioned at roll end face, bearing housing is provided with the bearing box end cap of spheric, between this bearing housing and roll, be provided with labyrinth ring, be respectively arranged with a conical surface baffle ring at labyrinth ring two ends.

2. bar is remained silent the novel bearing box seal device of vertical mill as claimed in claim 1, it is characterized in that: described labyrinth ring dress roller is provided with O type back-up ring, thus avoids iron scale to be deposited in around bearing housing.
