Background technique
Annular gasket is often used in the shaft drive, for example in motor or other engineering machinery, to adjust installation precision, to carry out axially locating, thrust etc.
Generally, the pad of installing can produce friction to the parts that move with contact concurrent looks on every side with it in the course of the work, therefore need be lubricated pad, and be that the interior machine oil of direct utilized device provides lubricated under a lot of situation.Under the prior art condition, a kind of mode is to open the hole at pad, and how lubricated the more face of perforate be more big, and lubrication effect is more good.But the rigidity of the many pads of Kong Yue and intensity are more poor, and the ability of bearing axial force is more poor.Another kind of mode is to process oil groove at pad, and general oil groove is radially radial arrangement, and oil groove can guarantee the intensity of pad like this and be convenient to dosing, replenishing of lubricating oil at interior circle or cylindrical place opening.But, on the one hand, between each oil groove on circumferential direction the space, cause the distribution effect at friction surface of lubricating oil unsatisfactory, on the other hand, contact with pad and the effect of the rubbing surface of the parts of relative movement under, fluid also can radially throw away under centrifugal action when circumferentially advancing, and radially oil groove provides passage for throwing away of fluid, causes the fluid loss, this has obviously reduced the lubrication effect of fluid to pad, has shortened the working life of pad.
General pad is cheap element, and usage quantity is also more, and therefore the more hidden inconvenience dismounting in mounting point requires cost of labor that the maintainer regularly will pay for pad supplemental lubrication grease or periodic replacement pad far above the pad cost.In fact, the maintainer generally can wait for when the wearing and tearing of pad surpass certain limit and for example cause device such as motor problem such as big noise or other fault to occur, just can carry out pad passively and change.Therefore how to keep the effect endurance of lubricating oil on pad to prolong pad working life to slow down wearing and tearing to greatest extent, be one and have more cost-benefit direction of dealing with problems.
Summary of the invention
The objective of the invention is to overcome above-mentioned shortcoming, provide a kind of lubrication effect better pad.
For achieving the above object, the invention provides following technological scheme:
A kind of pad, described pad are annular, and the surface of described pad has oil groove, and described oil groove is that snail is linear, and an end of described oil groove is at the cylindrical place of described pad opening, and the other end seals, and described oil groove is at least around described interior one week of circle.
Preferably, on the direction of described oil groove end to sealing from an end of opening, width reduces gradually.
Preferably, described width reduces continuously gradually.
Preferably, on the direction of described oil groove end to sealing from an end of opening, the degree of depth reduces gradually.
Preferably, the described degree of depth reduces continuously gradually.
Preferably, described pad two sides all has oil groove.
Preferably, described pad is one-body molded of punching press.
A kind of motor comprises: timing gear; Timing chain; Oil nozzle; Aforesaid pad; Described timing chain drives described timing gear, described timing gear are fitted with described pad and relative described pad rotation, the Hand of spiral of the described relatively pad of described timing gear is done opposite spin, and described oil nozzle provides fluid for described chain and described pad simultaneously.
A kind of automobile has adopted aforesaid pad on the described automobile.
Pad of the present invention adopts the form of oil groove, has guaranteed rigidity, the intensity of pad.Oil groove is at an end opening at cylindrical place, being convenient to fluid enters, and because oil groove is that snail is linear, therefore the suffered centrifugal force major part of fluid in the oil groove is offset by the opposite force that the oil groove wall is provided, fluid enters oil groove and advances along the helix direction of oil groove from the opening end of oil groove cylindrical under the effect of the parts of gravity and pad friction.The other end sealing of oil groove, avoided fluid further to flow out, thereby under the condition that unit time inner fluid magnitude of recruitment equates, prolonged the life period of fluid in oil groove, fluid can be maintained in the oil groove, thus lubrication effect continue longer, correspondingly, the frequency of supplemental lubrication liquid can be lowered, and has reduced fluid loss and the cost of overhaul.And helix guaranteed can both circumferentially be lubricated at whole surperficial Upper gasket at least around interior one week of circle, and therefore lubricated lasting effect is better, the pad longer service life.
Further, on the direction of the end from an end of opening to sealing, the width of oil groove reduces gradually, and perhaps the degree of depth of oil groove reduces gradually, makes the diameter of the oil duct that oil groove and circumferential component surround reduce gradually.Because fluid enters from cylindrical, therefore after adding lubricant oil, when the relative Hand of spiral of equipment starting circumferential component is done opposite spin, producing under the effect of the parts that rub with pad, more away from the fluid entrance, the flow velocity of fluid is more fast, and the static pressure of fluid is more low, make fluid invade the whole gasket surface of profit rapidly, and be conducive to the maintenance of fluid.
Further, width gradually changes and the processing mode of punching press moulding continuously with the degree of depth, all has advantage easy to process.
Further, all process oil groove on the pad two sides, can prevent misloading when Hand of spiral is identical, can adapt to the different directions that relatively rotates when Hand of spiral is opposite.
After the rotating shaft position of motor or automobile is installed according to pad of the present invention, can reduce generating noise, reduce to overhaul the frequency.
Description of drawings
Next will describe in further detail specific embodiments of the invention by reference to the accompanying drawings, wherein:
Fig. 1 is the plan view of the pad of embodiments of the invention;
Fig. 2 is the sectional view along the A-A line among Fig. 1;
Fig. 3 is the fundamental diagram that has adopted the motor of the pad in the embodiments of the invention.
Mark among the figure: pad 100, interior circle 110, cylindrical 120, oil groove 130, first end 131, second end 132.
Embodiment
With reference to figure 1, pad 100 is annular, circle 110 and cylindrical 120 in having.Be close to pad 100 and in relative rotation the circumferential component (not shown) can produce friction with the surface of pad 100.Has spiral yarn shaped oil groove 130 on pad 100 and the surface that circumferential component is fitted and generation rubs.First end, 131 sealings of oil groove 130, second end 132 is at cylindrical 120 place's openings, from first end, 131 to second ends 132, oil groove 130 at least twice pass or arrive pad 100 a diameter place line A-A(simultaneously this line also as the cutting line of Fig. 2), namely oil groove 130 is at least around interior 110 1 weeks of circle.Oil groove 130 is at least around having guaranteed interior 110 1 weeks of circle can access lubricated on the surface of whole circumferential scope internal gasket 110.Suppose that the circumferential component (not shown) that produces friction with pad 100 rotates clockwise, machine oil adds beyond cylindrical 120, in the starting stage of equipment starting, the rotating speed of circumferential component is more and more faster, therefore fluid in the oil groove 130 produced from the effect of the radially outer centrifugal force in the center of circle of interior circle 110 and tangential force at fluid owing to tend to make circular movement with circumferential component under the effect of the viscous force of friction, suction-operated and the fluid of circumferential component itself.And because oil groove 130 is that snail is linear, so any point place on the wall of oil groove 130, centrifugal force is most of can be offset by the reaction force that wall provided at this some place, and can only flow along tangent direction, be the dotted arrow direction among Fig. 2, this direction is pointed to first end 131 from second end 132.And on this direction, the width W of oil groove 130 reduces gradually, when the equipment starting shaft rotates after adding lubricant oil, producing under the effect of the parts that rub with pad, more away from the fluid entrance, the flow velocity of fluid is more fast, and the static pressure of fluid is more low, make fluid invade the whole gasket surface of profit rapidly, and be conducive to the maintenance of fluid.From the above description as can be known, the oil groove 130 of pad 100 is designed to the linear working principle of snail, just the opposite with the working principle of scroll casing type water pump, the working principle of scroll casing type water pump is to make water flow out water pump smoothly and have bigger static pressure, and the working principle of the linear oil groove 130 of snail is fluid to be advanced along oil duct 130 smoothly invade profit and static pressure reduces gradually, and pad 100 around parts can be understood that to play the effect of water pump vane.The reducing gradually of the width of oil groove 130 comprises that cascade reduces to reduce gradually with continous way gradually, pad 100 can be by mode moulding such as punching press, millings, for the consideration of work efficiency, adopt impact style width one-body molded, that employing reduces continuously to have advantage.Because first end 131 of pad 100 seals, so fluid arrives and can not move on behind first end 131 again and flow out oil groove 130, and under the situation of external dressing, this has advantage.
Fig. 2 has shown the variation of the degree of depth of oil groove 130 on the fluid flow direction.Second end, 132 place's depth H, 1 maximum at opening, depth H 3 minimums at first end, 131 places that seal, the size of the depth H of locating between first end 131 and second end 132 2 is between H1 and the H3, and variation and the variation on the width on this degree of depth are similar, also change gradually, comprise gradually changing of cascade and continous way, preferably reduce gradually continuously.Variation on this degree of depth is played identical beneficial effect with the variation on the width, therefore repeats no more.
Fig. 3 is that example has illustrated a kind of motor that has adopted pad 100 with the timing wheel.Gear 500 is the timing gear in the timing train, and for example fuel pump gear, water pump gear, generator gear etc. receive the driving of the power that comes from bent axle by the timing chain (not shown), rotate in the axis hole of flange 400 with live axle 200.Flange 200 is fixedly mounted on the cylinder body 300, and pad 100 is enclosed within on the axle 200, between timing gear 500 and flange 400.To seeing that timing gear 500 turn clockwise, so timing gear 500 are that pad 100 is produced the parts of friction from R, and this sense of rotation is opposite with respect to the Hand of spiral of first end, 131 to second ends 132 of oil groove 130.When generally adopting timing chain, the capital utilizes the oil nozzle (not shown) to provide oil lubricating for timing chain, and because the opening of pad 100 is at cylindrical 120 places, so the machine oil that oil nozzle sprays is in gravity effect or mobile in oil leab, from second end, the 132 inflow oil grooves 130 of opening.
Those of ordinary skills can imagine at an easy rate that the pad 100 among the present invention can also be applied to other position of motor, perhaps are applied to for example other position such as wheel axle, perhaps are applied to other mechanical field.And when two surfaces of pad 100 all process oil groove 130, if the Hand of spiral of two sides oil groove identical (being all left hand screw or right-hand screw) then can play preventing that pad 100 dresses are anti-; If the Hand of spiral of two sides oil groove is opposite, then can select the applying rubbing surface of pad 100 and these parts according to the relative sense of rotation (clockwise or counterclockwise) of circumferential component, the pad versatility is better.Therefore the design of two sides oil groove has advantage.
Though the present invention is described in conjunction with above embodiment, the present invention is not limited to above-described embodiment.Those of ordinary skills can easily make amendment to it and change, but do not leave essence design of the present invention and scope.
