RU98117516A - DEVICE AND METHOD FOR DISCHARGEING LIQUID LUBRICANT MATERIAL FROM SUPPORT DEVICE - Google Patents

Claims (11)

1. A device (1) for removing liquid lubricant (8) from a support device (2) for a shaft (4) rotating around an axis (3), which has a bearing (5) to be lubricated with lubricant (8), on which the shaft rests (4) at least one seal (7) surrounding the shaft (4) surrounding the shaft (4) and located at the first end (9a) of the bearing (5), a collector (10) surrounding the shaft, adapted to trap and exhaust outlet at the first end (9A) of the lubricant (8), characterized in that geodesically under the bearings com (5) provides a lubricant sump (11) that is connected to the lubricant drain (12), and the manifold (10) has a deflecting channel (25) passing through the lubricant sump (11) for accelerated lubricant discharge (8) .  2. The device (1) according to claim 1, characterized in that the second end (9b) of the bearing (5) is located along the axis (3) opposite the first end (9a) and for the direct flow of lubricant (8) into the sump (11) lubricant is connected hydraulically to it.  3. The device (1) according to claim 2, characterized in that there is another manifold (10a) located near the second end (9b) for receiving and discharging the lubricant emerging from the second end (9b) (8).  4. The device (1) according to one of the preceding paragraphs., Characterized in that the bearing (5) is located between the seal (7) and the collector (10).  5. The device (1) according to one of the preceding claims, characterized in that the seal (7) has a seal body (6) in which a suction chamber (13) is provided, and at least two sealing tapes (15), surrounding the shaft (4) and forming an intermediate space (14), which is hydraulically connected to the suction chamber (13).  6. The device (1) according to claim 5, characterized in that the suction chamber (13) has an opening (16) made in the seal housing (6).  7. The device (1) according to one of claims 5 or 6, characterized in that the suction chamber (13) is connected to the suction pipe (17), which passes through the sump (11) of the lubricant and enters the drain (12) for the lubricant material, so that its cross section (18) is narrowed by the suction pipe (17).  8. The device (1) according to one of the preceding paragraphs, characterized in that the supporting device (2) comprises an end bearing (5a).  9. A method for removing liquid lubricant (8) from a support device (2) for a shaft (4) rotating around an axis (3), which comprises a bearing (5) provided with a lubricant (8), and on which a shaft (8) is supported at least one seal (7) located near the bearing (5) and surrounding the shaft (4) and one collector (10) attached to the first end (9a) of the bearing (5), by means of which the outlet to the first end (9a) lubricant (8), characterized in that from the collector (10) through passing through located g odezicheski lower bearing (5) the sump (11), diverting the lubricant channel (25), a lubricant (8) from the acceleration fed to the drain (12) for lubricant.  10. The method according to p. 9, characterized in that the lubricant (8) emerging from the second end (9b) located along the axis opposite the first end (9a) of the lubricant is led directly to the lubricant sump (11), so that the deflecting channel (25) ends in the lubricant-filled area (19) of the sump (11) of the lubricant.  11. The method according to p. 9 or 10, characterized in that the lubricant (8) from the intermediate space (14) formed between the two sealing tapes (15) of the seal (7) is diverted to the suction chamber (13) and from there through the sump (11) lubricant suction pipe (17) into the drain (12) for lubricant.
