Abstract
The utility model discloses an oil lubricating bearing sealing device composed of a bearing box, a bearing gland, etc. An oil ring is sheathed and fixed on a rotary shaft and arranged in the bearing gland, and the bearing gland is sheathed on the rotary shaft and is fixedly connected with a bearing box cover. The utility model is suitable for sealing bearings of various machines and can be extensively used for various velocity occasions. The utility model has simple structure, low fabrication cost and long service life, and the sealing effect can achieve the zero leakage.
Description
Technical field: the utility model relates to mechanical transmission fields, and particularly the oil-lubricated bearing seal arrangement is applicable to oil to be the bearing seal of the various machines of lubricant medium, can be widely used in various speed occasions.
Background technique: be used for the associated sealing arrangement for bearings on the machines such as various lathes, pump, blower fan, gear-box at present, common having is following several: the packing seal of 1, filling type, fill felt or filler in the circular groove between transmission shaft and housing, use gland and screw in compression then, stop up and reveal the gap, reach the purpose of sealing.Defective is between filler and the axle relative movement to be arranged, and is easy to generate wearing and tearing, causes revealing, and working life is limited.2, extrusion pressing type body sealing has O shape, square etc. by seal ring sectional shape branch.Be extruded the generation impacting force in advance by seal ring in groove, the close encapsulation gap reaches the purpose of sealing.Defective be seal ring with axle between relative friction, easily aging, and axle produced wearing and tearing, cause leakage, working life is very short.3, flexural mode elastomeric seal relies on lip limit and the magnitude of interference of the diameter of axle and the contractile force of spring, makes it axle is produced certain power of radially holding tightly, blocks and reveals the gap, reaches the purpose of sealing.This sealing also has the shortcoming of the difficulty changed except that the defective with extrusion pressing type.4, labyrinth seal forms very little labyrinth gap and realizes sealing between revolving part and fixed block.This sealing does not reach zero leakage, and for the low speed occasion, effect is bad especially.5, spiral seal utilizes the screw pump principle, when medium during along clearance leakage, borrows screw action that medium is back, to guarantee sealing.Dynamic and static gaps is little, otherwise liquid can not be attached on axle and the surface in hole simultaneously, and it is invalid not have an effect sealing of catching up with oil, so this sealing will have certain machining accuracy.Also certain running accuracy to be arranged, otherwise the sound friction easily takes place.
Summary of the invention: the purpose of this utility model is to make a kind of lube shaft bearing sealing device, overcomes poorly sealed, the easy leakage of above-mentioned bearing seal form, the defective that the life-span is short, replacing is difficult.Make that a kind of nothing is leaked, the life-span is long, easily changeable associated sealing arrangement for bearings makes its sealing that is used for lubricant oil, also can be used for the sealing of other liquid.
The present technique solution can reach above-mentioned purpose: the oil-lubricated bearing seal arrangement is made up of bearing housing, bearing gland etc., and disc wears to be fixed on and is loaded on the rotatingshaft in the bearing gland, and bearing gland is set on the rotatingshaft and is connected and fixed with bearing box cover.
The utility model is compared with other lubrication and seal form, and simple in structure, low cost of manufacture need not any maintenance, and the life-span is long.Good sealing effect can reach zero leakage.Change structure and be applicable to sealing lubricating oil and other liquid medium, can be widely used in various speed occasions.
Description of drawings: accompanying drawing is a structural representation of the present utility model.
Embodiment: below in conjunction with example the utility model is done further detailed description: referring to accompanying drawing, the oil-lubricated bearing seal arrangement, form by bearing housing 10, bearing gland 7 etc., disc 9 wears and is fixed on the rotatingshaft 8, be loaded in the bearing gland 7, means of fixation can have multiple, as pin, screw, screw thread etc., is radially to be fixed on the rotatingshaft 8 with screw 6 in the accompanying drawing.Bearing gland 7 is set on the rotatingshaft 8 and is connected and fixed with bearing box cover 1.Disc 9 is " bowl " or " dish " shape, the inner chamber of bearing gland 7 is " bowl " shape, in-flanges is arranged in the central, " bowl " of disc 9 or " dish " shape be uncovered to be buckled in outside the in-flanges of bearing gland 7, the uncovered internal diameter of its " bowl " or " dish " shape is greater than the external diameter of in-flanges, leave certain space between in-flanges and the disc 9, the sound friction of avoiding axial float to cause.The inner ring of bearing 2 is fixing with back of the body cap 5.Bearing gland 7 has the step of connection with the joint of bearing housing 1, connects between step and the bearing box cover 1 sealing gasket 3 is housed, and bolt 4 is connected and fixed bearing gland 7 and bearing box cover 1.Work as machine works, during rotatingshaft 8 running, under the centrifugal action of disc 9, got rid of to the surface of internal cavity of bearing gland 7, flow to bearing housing 10 along inwall again along the lubricant oil of rotatingshaft 8 axial leakages or liquid.Because of making the flange shape in the bearing gland 7, lubricant medium can not flow on the rotatingshaft 8 and cause leakage.The outward edge of disc 9 surpasses the in-flanges of bearing gland 7 simultaneously, makes in-flanges near " bowl " end, plays good sealing effect.
