Background technique
Annular gasket is often used in shaft drive, such as, in motor or other engineering machinery, to adjust installation precision, to carry out axially locating, thrust etc.
Generally, the pad installed can produce with surrounding to contact concurrent raw relative movement parts with it in the course of the work and rub, and therefore needs to lubricate pad, and is that machine oil in direct utilized device provides lubrication in a lot of situation.Under prior art condition, a kind of mode opens hole on pad, and perforate more lubrications face is larger, and lubrication effect is better.But rigidity and the intensity of the many pads of Kong Yue are poorer, and the ability of bearing axial force is poorer.Another kind of mode processes oil groove on pad, general oil groove radially radial arrangement, and oil groove is at inner circle or cylindrical place opening, can ensure the intensity of pad like this and be convenient to the dosing of lubricating oil, supplement.But, on the one hand, spaced in circumferential direction between each oil groove, cause the unsatisfactory at the distributed effect of friction surface of lubricating oil, on the other hand, with pad contacts and under the effect of the rubbing surface of the parts of relative movement, fluid also can throw away in radial direction under centrifugal action while circumference is advanced, and radial oil groove is throwing away of fluid provides passage, causes fluid to lose, this obviously reduces the lubrication effect of fluid to pad, shortens the working life of pad.
General pad is cheap element, and usage quantity is also more, the more hidden inconvenience dismounting in mounting point, therefore requires maintainer regularly for pad supplemental lubrication grease or regularly replaces cost of labor that pad will pay far above pad cost.In fact, maintainer generally can wait for that the wearing and tearing of pad exceed certain limit when causing the devices such as such as motor to occur the problem such as larger noise or other fault, just can carry out pad replacing passively.Therefore how keep the effect duration of lubricating oil on pad to extend 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 object 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 be annular, and the surface of described pad has oil groove, and described oil groove is that snail is linear, and one end of described oil groove is at the cylindrical place opening of described pad, and the other end is closed, and described oil groove is at least around described inner circle one week.
Preferably, described oil groove from one end of opening to the direction of the one end closed, width reduces gradually.
Preferably, described width reduces continuously gradually.
Preferably, described oil groove from one end of opening to the direction of the one end closed, 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, comprising: timing gear; Timing chain; Oil nozzle; Pad as above; Described timing chain drives described timing gear, described timing gear and described pad are fitted and are rotated relative to described pad, the Hand of spiral of the relatively described pad of described timing gear does opposite spin, and described oil nozzle is simultaneously for described chain and described pad provide fluid.
A kind of automobile, described automobile have employed pad as above.
Pad of the present invention adopts the form of oil groove, ensure that the rigidity of pad, intensity.Oil groove is in the one end open at cylindrical place, be convenient to fluid enter, and due to oil groove be that snail is linear, therefore the centrifugal force major part suffered by the fluid in oil groove the opposite force that provides by oil groove wall offset, fluid, under the effect of the parts of gravity and packing friction, enters oil groove and helix direction along oil groove is advanced from the opening end of oil groove cylindrical.The other end of oil groove is closed, avoid fluid to flow out further, thus under the condition that unit time inner fluid magnitude of recruitment is equal, extend the life period of fluid in oil groove, enable fluid be maintained in oil groove, therefore lubrication effect continue longer, correspondingly, the frequency of supplemental lubrication liquid can be lowered, and reduces fluid loss and the cost of overhaul.And helix is at least around inner circle one week, ensure that pad can obtain circumference lubrication on the whole surface, therefore lubricates lasting effect better, pad longer service life.
Further, from one end of opening to the direction of the one end closed, the width of oil groove reduces gradually, or the degree of depth of oil groove reduces gradually, and the diameter of the oil duct that oil groove and circumferential component are surrounded reduces gradually.Because fluid enters from cylindrical, therefore after adding lubricant oil, when opposite spin is done in equipment starting circumferential component opposed helical direction, under producing the effect of the parts rubbed with pad, more away from fluid entrance, the flow velocity of fluid is faster, and the static pressure of fluid is lower, make fluid invade rapidly the whole gasket surface of profit, and be conducive to the maintenance of fluid.
Further, the processing mode shaping together with punching press that gradually changes continuously of hierarchy structure, all has advantage easy to process.
Further, all process oil groove on pad two sides, can anti-misloading when Hand of spiral is identical, can adapt to when Hand of spiral is contrary different relatively rotate direction.
Install after according to pad of the present invention at the rotating shaft position of motor or automobile, the generation of noise can be reduced, reduce the maintenance frequency.
Accompanying drawing explanation
Next will be described 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 in Fig. 1;
Fig. 3 is the fundamental diagram of the motor of the pad that have employed in embodiments of the invention.
Mark in figure: pad 100, inner circle 110, cylindrical 120, oil groove 130, first end 131, second end 132.
Embodiment
With reference to figure 1, pad 100 is annular, has inner circle 110 and cylindrical 120.To be close to pad 100 and circumferential component (not shown) can produce with the surface of pad 100 and rubs in relative rotation.Fit in pad 100 and circumferential component and occur that the surface that rubs has spiral yarn shaped oil groove 130.The first end 131 of oil groove 130 is closed, second end 132 is at cylindrical 120 place opening, from first end 131 to the second end 132, the line A-A(that oil groove 130 at least passed twice through or arrived a diameter place of pad 100 simultaneously this line also as the cutting line of Fig. 2), namely oil groove 130 is at least around inner circle 110 1 weeks.Oil groove 130 at least ensure that around inner circle and accesses lubrication in the surface energy of whole circumferential scope internal gasket 110 for 110 1 weeks.Suppose that producing with pad 100 the circumferential component (not shown) rubbed rotates clockwise, machine oil adds beyond cylindrical 120, in the starting stage that equipment starts, the rotating speed of circumferential component is more and more faster, tend to circle with circumferential component under the effect of fluid in oil groove 130 due to the viscous force of the friction of circumferential component, suction-operated and fluid itself, on fluid, therefore create the effect from the radially outer centrifugal force in the center of circle of inner circle 110 and tangential force.And due to oil groove 130 be that snail is linear, therefore any point place on the wall of oil groove 130, centrifugal force major part can the reaction force that provides by the wall at this some place offset, and can only flow along tangent direction, namely the dotted arrow direction in Fig. 2, first end 131 is pointed to from the second end 132 in this direction.And in the direction in which, the width W of oil groove 130 reduces gradually, when after adding lubricant oil, equipment starting shaft rotates, under producing the effect of the parts rubbed with pad, more away from fluid entrance, the flow velocity of fluid is faster, and the static pressure of fluid is lower, make fluid invade rapidly the whole gasket surface of profit, and be conducive to the maintenance of fluid.Known from the above description, the oil groove 130 of pad 100 is designed to the linear working principle of snail, just the opposite with the working principle of spiral case type water pump, the working principle of spiral case type water pump makes water flow out water pump smoothly and has larger static pressure, and the working principle of the linear oil groove 130 of snail makes fluid carry out invading profit and static pressure reduces gradually along oil duct 130 smoothly, and the peripheral parts of pad 100 can be understood to the effect playing water pump vane.The reduction gradually of the width of oil groove 130 comprises cascade and reduces gradually to reduce gradually with continous way, pad 100 can be shaping by the mode such as punching press, milling, for the consideration of work efficiency, the width that impact style is one-body molded, employing reduces continuously is adopted to have advantage.Because the first end 131 of pad 100 is closed, therefore fluid can not move on after arriving first end 131 again and flow out oil groove 130, and when from external dressing, this has advantage.
Fig. 2 indicates the change of the degree of depth of oil groove 130 on fluid flow direction.Maximum in the second end 132 place depth H 1 of opening, minimum in the depth H 3 at first end 131 place closed, the size of the depth H 2 located between first end 131 and the second end 132 is between H1 and H3, and the change in this degree of depth and the change on width similar, also change gradually, comprise gradually changing of cascade and continous way, preferably reduce gradually continuously.Change in this degree of depth plays identical beneficial effect with the change on width, therefore repeats no more.
Fig. 3 is be illustrated a kind of motor that have employed pad 100 with timing wheel train.Gear 500 is the timing gear in timing wheel train, such as gear of fuel pump, water pump gear, generator gear etc., is received the driving coming from the power of bent axle, rotate with live axle 200 in the axis hole of flange 400 by timing chain (not shown).Flange 200 is fixedly mounted on cylinder body 300, and pad 100 is enclosed within axle 200, between timing gear 500 and flange 400.From R to seeing that timing gear 500 turn clockwise, therefore timing gear 500 are parts pad 100 being produced to friction, and this sense of rotation is contrary relative to the Hand of spiral of first end 131 to the second end 132 of oil groove 130.During general employing timing chain, capital utilizes oil nozzle (not shown) to provide oil lubricating for timing chain, and due to the opening of pad 100 be at cylindrical 120 place, therefore the machine oil that oil nozzle sprays flows at Action of Gravity Field or in oil leab, flows into oil groove 130 from the second end 132 of opening.
Those of ordinary skill in the art can imagine easily, and the pad 100 in the present invention can also be applied to other position of motor, or is applied to other positions such as such as wheel axle, or is 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 pad 100 anti-loaded; If the Hand of spiral of two sides oil groove is contrary, then can select the laminating rubbing surface of pad 100 and these parts according to the relative sense of rotation of circumferential component (clockwise or counterclockwise), pad versatility is better.Therefore the design of two sides oil groove has advantage.
Although the present invention is described in conjunction with above embodiment, the present invention is not limited to above-described embodiment.Those of ordinary skill in the art can easily modify to it and change, but do not leave essential idea of the present invention and scope.
