Abstract
The invention discloses a sealing structure for a roll shaft and a roll box of a high speed wire rolling mill. The sealing structure comprises the roll shaft with a stepped structure, wherein the roll shaft comprises a large diameter part and a small diameter part which are connected; the small diameter part is a tapered shaft; the outer circumference of the connected position of the small diameter part and the large diameter part is provided with an inner ring oiler and an outer ring oiler; the cross sections of the inner and outer ring oilers are L-shaped; the bottoms of the inner and outer ring oilers are provided with seal grooves; O-rings are arranged in the seal grooves; the cross section of the spliced inner and outer ring oilers is U-shaped; the inner walls of the inner and outer ring oilers are provided with wear-resistant coatings; and a double lip seal is arranged in the U-shaped interior of the inner and outer ring oilers. The sealing structure improves the self lubrication of the product and the fitness of the product and rubber, and prevents water from entering the roll shaft and oil from leaking from an oil film bearing.
Description
Technical field
The present invention relates to high-speed rod-rolling mill roll mandrel and roller case hermetically-sealed construction.
Background technology
High-speed rod-rolling mill roller case is the core unit that high-speed rod is produced, and is extremely important to the Quality and yield of high-speed rod.Use double-lip seal to contact sealing between roll mandrel and the roller case, this structure has interior ring oiler, double-lip seal, outer ring oiler forms, inside and outside ring oiler roll mandrel rotates together during use, double-lip seal is in roller case one, and with respect to roll mandrel, inside and outside ring oiler is static, roll mandrel speed when High Rotation Speed can reach 11000 rev/mins, the double-lip seal of inside and outside ring oiler inner surface and rubber acutely rubs, if ring oiler inner surface fineness, when Wear vesistance would be bad, can damage double-lip seal, the roller case is leaked, affect the high speed wire rod mill oil piping system, produce the excessively heated axle phenomenon when serious.
Summary of the invention
Technical problem to be solved by this invention just provides a kind of high-speed rod-rolling mill roll mandrel and roller case hermetically-sealed construction, improves sealing effectiveness, avoids the roller case to leak.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: high-speed rod-rolling mill roll mandrel and roller case hermetically-sealed construction, the roll mandrel that comprises hierarchic structure, this roll mandrel comprises continuous large-diameter portion and minor diameter part, minor diameter part is diminished shaft, described minor diameter part and large-diameter portion joint outer circumferential sides are provided with interior ring oiler and outer ring oiler, described interior ring oiler and outer ring oiler cross-sectional profiles are L shaped, described interior ring oiler and outer ring oiler bottom surface are provided with seal groove, be provided with O-ring seals in the seal groove, cross-sectional profiles is U-shaped after interior ring oiler and the outer ring oiler amalgamation, described interior ring oiler and outer ring oiler inwall are provided with wear-resistant coating, and the U-shaped inside of described interior ring oiler and outer ring oiler is provided with double-lip seal.
Preferably, described wear-resistant coating is supersonic speed sprayed molybdenum coating, and described supersonic speed sprayed molybdenum coating adopts high temperature resistant oiliness resin sealing of hole to process.
Preferably, described outer ring oiler top is provided with the chimb parallel with the base.
Preferably, described minor diameter part is provided with annular groove in abutting connection with outer ring oiler.
Inside and outside ring oiler inwall supersonic speed sprayed molybdenum coating among the present invention, greatly improved the anti-attrition of product, make the coefficient of friction of the double-lip seal of ring oiler inwall and rubber drop to minimum, improved greatly the service life of double-lip seal, product is processed with high temperature resistant oiliness resin sealing of hole behind sprayed molybdenum, improved the stickiness of self-lubricity and product and the rubber of product, prevented that water from entering roll mandrel and oil spills in filmatic bearing.
Description of drawings
The invention will be further described below in conjunction with the drawings and specific embodiments:
Fig. 1 is structural representation of the present invention;
Fig. 2 is outer ring oiler structural representation;
Fig. 3 is interior ring oiler structural representation.
The specific embodiment
Below in conjunction with Fig. 1 to Fig. 3 high-speed rod-rolling mill roll mandrel of the present invention and roller case hermetically-sealed construction are made and to be specified.The roll mandrel 1 that comprises hierarchic structure, this roll mandrel comprises continuous large-diameter portion 11 and minor diameter part 10, minor diameter part is diminished shaft, described minor diameter part and large-diameter portion joint outer circumferential sides are provided with interior ring oiler 4 and outer ring oiler 2, described interior ring oiler and outer ring oiler cross-sectional profiles are L shaped, described interior ring oiler and outer ring oiler bottom surface are provided with seal groove 21, be provided with O-ring seals 5 in the seal groove, cross-sectional profiles is U-shaped after interior ring oiler and the outer ring oiler amalgamation, described interior ring oiler and outer ring oiler inwall are provided with wear-resistant coating, and the U-shaped inside of described interior ring oiler and outer ring oiler is provided with double-lip seal 3.Described wear-resistant coating is supersonic speed sprayed molybdenum coating, and described supersonic speed sprayed molybdenum coating adopts high temperature resistant oiliness resin sealing of hole to process.Described outer ring oiler top is provided with the chimb parallel with the base 20.Described minor diameter part is provided with annular groove 101 in abutting connection with outer ring oiler.
Because inside and outside ring oiler inwall is not easy to wear and tear the service life of having improved greatly double-lip seal with supersonic speed sprayed molybdenum coating, the slide surface 22 that inside and outside ring oiler inwall contacts with double-lip seal.
