Abstract
The utility model discloses a roll collar capable of easily being maintained for a rolling mill. The inner diameter of the roll collar can ensure that the roll collar can be in interference fit on the roll neck of a roller, one end of the roll collar is matched with the root part of the roll neck of the roller, the other end thereof is matched with the step of the roll neck of the roller, a groove is arranged on the sealing position of the excircle of the roll collar and a rotating shaft and internally sprayed with a layer of ceramic. Since the surface layer of the utility model has high hardness, the utility model is difficult to wear, has long service life, good sealing effect and simple and convenience maintenance.
Description
Technical field
The utility model relates to a kind of seal connector that high-speed rotating shaft or roller and bearing housing are installed together, and relates in particular to the seal connector that a kind of aluminium strip, aluminium foil mill working roll roll neck and bearing housing are installed together.
Background technology
At present, adopt the rotary shaft sealing sealing between the roll neck of domestic most of aluminium strip, aluminium foil mill roll and seal connector that bearing housing is installed together and the bearing housing.The steel collars that rotary shaft sealing lip and heat treatment hardness are very high contacts, and the collars interference is assemblied on the roller neck.Because roll rotational speed is very high, collars cylindrical heat treatment hardness inequality, collars and rotary shaft sealing contact position cylindrical are often ground groove by the axle envelope in the use, and seal failure causes oil leak pollution ROLLING OIL in the bearing housing.Secondly need when changing the collars that damages roll bearing inner ring and collars are dismantled successively, and pack into new collars and bearing inner race, grinding collars cylindrical and bearing inner ring cylindrical then, operation is loaded down with trivial details.
Summary of the invention
The utility model solves the above-mentioned problems in the prior art exactly, and a kind of surface hardness height, not easy to wear is provided, long service life, and good sealing effect, easy to maintenance, milling train is with the collars of easy care easily.
For addressing the above problem, technical solution of the present utility model is: a kind of milling train collars of easy care, the collars internal diameter can guarantee that its interference is assemblied on the roller neck, the root of one end and roller neck is complementary, the step place of the other end and roller neck is complementary, it is characterized in that: collars cylindrical and rotary shaft sealing position contacting have a groove, are coated with one deck ceramic layer in the groove.
Above-mentioned described collars internal diameter can guarantee that its interference is assemblied on the roller neck, and the magnitude of interference between collars internal diameter and the roller neck is 0.05-0.12mm.
The thickness of the ceramic layer of above-mentioned described collars can guarantee the monolateral 0.1mm of the having thickness of collars stock removal, and ceramic layer thickness is at 0.3-0.4mm after the assurance grinding.
Collars is packed into behind the roller neck, and grinding collars excircle dimension and roughness reach the rotary shaft sealing requirement, guarantee the axiality of collars and bearing inner race during grinding.Ceramic surface hardness height is difficult for being rotated the wearing and tearing of axle envelope; If the collars working face damages, do not need to dismantle collars, damaging surface is ground away, ceramic coated again, be ground to requirement again and get final product.The utility model surface hardness height, not easy to wear, long service life, good sealing effect, easy to maintenance, convenient.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is assemblied in assembling schematic diagram on bearing inner race and the roller neck for the utility model;
Fig. 3 is assemblied in assembling internal structure schematic diagram on bearing housing and the roller neck for the utility model.
The specific embodiment:
Below in conjunction with drawings and Examples the utility model is further specified.
As Fig. 1, Fig. 2 and shown in Figure 3, collars 2 internal diameters can guarantee that its interference is assemblied on roll 6 roll necks, and the magnitude of interference between collars 2 internal diameters and roll 6 roll necks is 0.05-0.12mm.One end 4 of collars 2 is complementary with the root of roll 6 roll necks, and the other end 1 is complementary with the step place of roll 6 roll necks.Collars 2 cylindricals and rotary shaft sealing 9 position contacting have a groove, are coated with one deck ceramic layer 3 in the groove; The thickness of ceramic layer 3 can guarantee the collars 2 monolateral 0.1mm of having thickness stock removals, and the thickness of ceramic layer 3 is at 0.3-0.4mm after the assurance grinding.5 is bearing inner race, and 8 is gland, and 10 is end cap, and 7 is bearing housing.
