Abstract
The utility model discloses a thin oil lubrication device under electric pressure, which is applied on a hot roll product line of a metal pressure machining production workshop. The thin oil lubrication device under electric pressure is characterized in that the side face of a dust cover (1) of the tail part of a pressure screw (5) is provided with an oil-spraying pipe (2), a protective cover (8) is arranged on the bearing seat of a thrust bearing (7), and the part of the protective cover close to the bottom surface is provided with an oil return pipe; and an oil inlet pipe (9) and an oil return pipe (10) are respectively arranged on the bearing seat of the thrust bearing. The device can greatly improve the lubrication state of screw thread pairs of the pressure screw and a pressure nut and the thrust bearing and is convenient for installation, maintenance and repair.
Description
Technical field
The utility model relates to the metallurgical machinery equipment technical field, particularly the hot rolling line in stress metal processing workshop housing screw and the thin oil lubricating device of thrust-bearing under the dynamic pressure that power on.
Background technique
In stress metal processing hot rolling manufacturing shop, generally on the hot rolling mill back-up chock, be furnished with electric screw down gear, be used for before each rolling pass, presetting fast roll gap.Electric screw down gear all should dispose lubricating fitting; Conventional electric-powered is depressed lubricating fitting; The screw pair and the thrust-bearing that comprise housing screw and screw box all adopt dry oil lubrication; Promptly in installation process and maintenance the time regularly be coated with drier oil, the lubricating cup intermittent oiling that perhaps is provided with from frame.
In this dry oil lubrication, will be when installing usually with being full of dry oil lubrication fat in the gap between housing screw and frame, the consumption of drier oil is very big, and utilization ratio is low; Though be provided with several lubricating cups that add drier oil on the frame,, refuel relatively more difficult from lubricating cup because drier oil amount demand is bigger; Simultaneously since the screwdown gear mounting point generally apart from ground more than 4 meters, there is potential safety hazard in the eminence operation; In addition, traditional dry oil lubrication effect is not ideal.
Summary of the invention
In order to overcome the problem in the background technique, the utility model discloses a kind of electronic thin oil lubricating device of depressing, this device can be improved the screw pair of housing screw and screw box and the lubrication state of thrust-bearing greatly.
In order to realize the foregoing invention purpose, the utility model adopts following technological scheme:
A kind of electronic thin oil lubricating device of depressing is provided with spray bar in the dust-proof cover side of housing screw afterbody, on the bearing support of thrust-bearing, protective housing is set, and said protective housing is provided with return tube near the place, bottom surface; Be respectively equipped with oil inlet pipe and return tube on the bearing support of said thrust-bearing.
Be better implement the invention, said oil inlet pipe and return tube are in the circumferencial direction of the thrust-bearing bearing support 30 ° of angles that stagger.
Be better implement the invention, said oil inlet pipe and return tube are at the circumferencial direction of the thrust-bearing bearing support 45 degree that staggers.
Because adopt aforesaid technological scheme, the utility model produces following good effect:
1, through relative set oil inlet pipe and return tube, form oil circulation and be lubricated, the thin oil oil circuit is smooth than dry oil lubrication fat, housing screw and thrust-bearing high lubricating effect; And thin oil circulating lubrication, consumption is few.
2, only the oil circuit pipeline need be set, and guarantee that pipeline is oil-proof, can guarantee normal lubricating, the installation and maintenance maintenance is convenient.
Description of drawings
Fig. 1 is the electronic structural representation of depressing thin oil lubricating device of the invention;
Among the figure: the 1-dust-proof cover; The 2-spray bar; 3-depresses retarder; The 4-frame; The 5-housing screw; The 6-screw box; The 7-thrust-bearing; The 8-protective housing; The 9-oil inlet pipe; The 10-return tube.
Embodiment
Present embodiment electronic depressed rare lubricating fitting, because of thrust-bearing to the having relatively high expectations of lubricant oil, the screw pair of housing screw and screw box and depress bearing fuel feeding and oil return respectively adopts thin oil circulating lubrication respectively.
In conjunction with Fig. 1; Screw pair for housing screw and screw box; At the side of dust-proof cover 1 installing spray bar 2, facing to housing screw 5 spray low pressure lubricant oil, lubricant oil stays along housing screw 5 tops through depressing retarder 3 and frame 4; Screw pair through housing screw and screw box flows in the protective housing 8, gets back to the thin oil case from the return tube of protective housing 8 bottoms again.
For thrust-bearing, oil inlet pipe 9 is housed, on the bearing support of thrust-bearing facing to the roller position spray low pressure lubricant oil of thrust-bearing, again from return tube 10 oil returns.For convenient statement, oil inlet pipe 9 and return tube 10 are illustrated in same bus position at circumferencial direction, in actual design among the figure; Oil inlet pipe 9 and return tube 10 are in circumferencial direction certain angle that can stagger; For making things convenient for pipe arrangement, be generally 30 ° or 45 °, after avoiding lubricant oil to come in from oil inlet pipe 9; Lubricating thrust bearing 7, and directly get back to fuel tank from return tube 10.
The rare lubricating fitting of the invention only needs to guarantee that above two thin oil oil circuits are smooth, and safeguards that the thin oil pipeline is oil-proof, can guarantee the electronic screw pair of depressing housing screw and screw box, and the good lubrication of thrust-bearing.
