Abstract
The utility model relates to a device to prevent the oil leakage from the ends of rolls. The device is applied to prevent the oil leakage of the cream oil from the bearing base of the upper and lower rolls of the rolling mills. The utility model consists of a bearing case, the inner shielding ring and outer shielding ring fixed on the roll, the inner pressing cap and the outer pressing cap arranged on the surface of the two ends of the case, and the roller bearing and ball bearing arranged in the bearing case and onto the ends of the rolls. The inner pressing cap and the outer pressing cap press the roller bearing and the ball bearing into the bearing case from two sides. The pressing caps are characterized that the inner rotary shaft lip seal is arranged on the inner pressing cap via the ring groove and the lips of the seal touches closely the outer surface of the inner shielding ring. The outer rotary shaft lip seal is arranged on the outer pressing cap via the ring groove and the lips of the seal touch closely the outer surface of the outer shielding ring. The life of the bearing can be prolonged, lubrication oil saved and the environment protected from pollution.
Description
Affiliated technical field
The utility model relates to a kind of device that prevents the terminal leakage of oil of roll, is applied to prevent the seepage of paste lubricating oil in the upper and lower roll end bearing block of rolling mill.
Background technology
Existing roll end equipment, by being fixed on bearing block on the rolling mill support (ground), being fixed on inner shield ring and outer back-up ring on the roll, being separately fixed at internal gland and the outer gland on the bearing block both ends of the surface and being installed in the bearing block and the roller bearing, the ball bearing that are enclosed within on the roll end are formed, inner shield ring, internal gland are in the inboard, outer back-up ring, outer gland be side outside, from the bearing block both ends of the surface roller bearing, ball bearing is squeezed in bearing block inside respectively.Owing to passed between upper and lower roll by being rolled workpiece, roll has little oscillation phenomenon to occur, with just needing a certain amount of slit between roll parts that fix and the parts that fix with bearing block, in order to avoid the damage parts.But because the existence in slit, the molybdenum bisuphide lithium based lubricating oil cream of bearing inside will flow out from the slit, has so both wasted ointment, has polluted workshop condition again, also need simultaneously constantly to refuel, allow oil flow to two class bearings from the bearing block inner passage from the bearing block top.And the water of cooling roll can enter bearing from the inner slit of bearing block, and extraneous dust can enter bearing from slit, bearing block outer end, and can not add lubricating oil in good time, and these all affect the service life of bearing.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, the device that prevents the terminal leakage of oil of roll that provide a kind of and stop leakage of oil from the slit, avoids extraneous dust, cooling water enters bearing from the slit.
The purpose of this utility model can reach like this, a kind of device that prevents the terminal leakage of oil of roll, it is by the bearing block that is fixed on the rolling mill support, be fixed on inner shield ring and outer back-up ring on the roll, be separately fixed at internal gland and outer gland on the bearing block both ends of the surface, and be installed in the bearing block and be enclosed within roller bearing on the roll end, ball bearing is formed, inner shield ring, internal gland is in the inboard, outer back-up ring, outer gland is side outside, respectively from the bearing block both ends of the surface with roller bearing, ball bearing is squeezed in bearing block inside, it is characterized in that on internal gland, inboard rotary shaft lip seal being installed, and make the lips of inboard rotary shaft lip seal be close to the outer surface of inner shield ring by annular groove; By annular groove outside rotary shaft lip seal is installed on the gland outside, and is made the lips of outside rotary shaft lip seal be close to the outer surface of outer back-up ring.
The utlity model has following advantage:
1, owing to reduced leakage of oil, avoids extraneous water, dirt to enter bearing, also just improved the service life of bearing greatly;
2, saved the consumption of lubricating oil:
3, avoided environmental pollution.

The specific embodiment
The utility model is further described below in conjunction with accompanying drawing.A kind of device that prevents the terminal leakage of oil of roll, it is by the bearing block (9) that is fixed on the rolling mill support, be fixed on inner shield ring (3) and outer back-up ring (19) on the roll (1), be separately fixed at internal gland (5) and outer gland (17) on bearing block (9) both ends of the surface, and be installed in the bearing block (9) and be enclosed within roller bearing (11) on the roll end, ball bearing (13) is formed, inner shield ring (3), internal gland (5) is in the inboard, outer back-up ring (19), outer gland (17) is in the outside, respectively from bearing block (9) both ends of the surface with roller bearing (11), ball bearing (13) is squeezed in bearing block (9) inside, inner shield ring (3) is fixed on the roll (1) by radial screw, outer back-up ring (19) is connected with external screw thread key fixed cover (23) by screw thread, put a sealing gasket (21) between back-up ring (19) and the ball bearing (13) outside, it is characterized in that going up and inboard rotary shaft lip seal is installed, and make the lips of inboard rotary shaft lip seal be close to the outer surface of inner shield ring (3) by annular groove (7) at internal gland (5); Gland (17) is gone up by annular groove (15) outside rotary shaft lip seal is installed outside, and makes the lips of outside rotary shaft lip seal be close to the outer surface of outer back-up ring (19).
Be installed in the rotary shaft lip seal of inside and outside gland (5,17) two annular grooves (7,15), it has the skeleton (31) of an annular, and the continuous annular rubber ring of same skeleton (31) one with lips (29,27), the outer ring spring (25) that binding round of interior rubber lip (27).Rotary shaft lip seal in two grooves (7,15), their interior rubber lip (27) is all nearest from bearing.Therefore, lubricating oil is sealed between the two interior rubber lips of medial and lateral rotary shaft lip seal, and extraneous water, dust are then by two outer rubber lips retaining outside.When roll (1) rotates because the application of force of spring (25), also just increased interior rubber lip (27) but in the wear extent that guarantees under the sealing prerequisite, and then obtained long-time oil tight effect.Because oil-proof for a long time, as also just to have improved bearing service life, saved the consumption of lubricating oil, avoided environmental pollution.
