Description
Technical Field
The utility model relates to a mechanical seal spare technical field especially relates to an altitude finishing mill sealing washer.
Background
The high-speed wire finishing mill is a high-precision and high-integration device and comprises a motor, a speed increasing box, a gear distribution box, a bevel gear box, a roller box and the like. The high-speed wire finishing mill has high rolling speed, and the sealing ring can accelerate the abrasion and wear speed under the working condition of high linear speed, thereby shortening the service life of the sealing ring. At present, the sealing ring of the high-speed wire finishing mill is manufactured by adopting NBR (nitrile-butadiene rubber), HNBR (hydrogenated nitrile butadiene rubber) and FKM (FKM) rubber materials by adopting a traditional production process, and the service life of the sealing ring is about 20 days. The sealing ring is damaged and leaked, cooling water liquid enters the case, so that the deterioration of lubricating oil and the damage of the bearing are caused, the production line is stopped, the sealing ring needs to be frequently stopped and replaced, and the production efficiency of the high-speed wire finishing mill is reduced. Therefore, there is a need to provide a new seal ring for a high-speed wire finishing mill to solve the above technical problems.
Disclosure of Invention
The utility model provides a technical problem provide an altitude finishing mill sealing washer, this sealing washer have stand wear and tear the advantage that the performance is strong, coefficient of friction is little, long service life.
In order to solve the technical problem, the utility model adopts the following technical scheme:
the utility model provides a sealing washer of altitude finishing mill which characterized in that: comprises a hydrogenated nitrile rubber ring, a metal support ring, an inner polytetrafluoroethylene sealing ring and an outer polytetrafluoroethylene sealing ring; hydrogenated nitrile rubber circle includes the support ring connector, is located external seal lip, the inner seal lip of support ring connector both sides, and support ring connector, external seal lip, inner seal lip combination are the annular rubber circle that the cross-section is the U-shaped, are equipped with the support ring draw-in groove on the support ring connector rampart, and metal support ring inlays in the support ring draw-in groove, the cohesion polytetrafluoroethylene sealing ring is attached on the outer side of inner seal lip, outer polytetrafluoroethylene sealing ring is attached on the external seal lip lateral surface, be equipped with on the lateral surface of inside and outside polytetrafluoroethylene sealing ring and get rid of the liquid line.
Furthermore, the liquid throwing line is a single spiral groove line and gradually extends from the inner ring to the outer ring of the inner polytetrafluoroethylene sealing ring and the outer polytetrafluoroethylene sealing ring.
The utility model discloses a hydrogenated nitrile butadiene rubber circle has better tear resistance, presses flexibly and becomes the resilience, has increased inside and outside polytetrafluoroethylene sealing ring with axle and pressure disk contact friction position department in two seal lip outsides of hydrogenated nitrile butadiene rubber circle, has improved self-lubricating, wear-resisting, the high temperature resistance ability of sealing washer, has prolonged the life of sealing washer. The utility model discloses including, set up on the lateral surface of outer polytetrafluoroethylene sealing ring and got rid of the liquid line, played and thrown the effect of getting rid of lubricating oil or cooling water, reduced the contact surface of seal lip and pressure disk simultaneously, can effectively reduce the frictional resistance that the sealing washer received, avoid the sealing washer overheated phenomenon to appear under the fast operating mode of high line.
