Description
Technical field
The utility model relates to a kind of gear, and more particularly, it relates to a kind of gear of automatic oiling.
Background technique
Gear; Wheel rim there is tooth to engage continuously and transmit motion and power
machineryelement is can the intermeshing mechanical parts having tooth.Include the gear teeth, teeth groove, wheel body, end face, normal plane, top circle, root circle, basic circle, standard pitch circle, the gear teeth are called for short tooth, it is each convex portion for engaging on gear, these convex portions generally arrange radially, the gear teeth on coupling gear contact with each other, and gear can be made to continue engagement running.Teeth groove is the space on gear between two adjacent teeth; End face is on cylindrical gears or cylindrical worm, perpendicular to the plane of gear or worm axis.End face is the plane at gear two ends.Normal plane refers to the plane perpendicular to gear teeth tooth trace.Top circle refers to the circle at tooth tip place.Root circle refers to the circle at bottom land place.The circle of pure rolling made by the generation line of basic circle formation involute.Standard pitch circle is the basic circle calculating gear physical dimension in end face.
When actual gear uses, be worn to prevent gear, increase gear life and meshing efficiency, generally all need to add gear oil after gear uses a period of time on gear, gear oil, based on petroleum oil base oil or synthetic lubricant fluid, adds a kind of important lubricant oil of extreme pressure anti-wear additives and oiliness improver modulation.For various gear drive, to prevent tooth surface abrasion, scratch, sintering etc., extend its working life, improve transmitted power efficiency, because general higher to the quality requirement of gear oil, so market cogs, the price of oil is also relatively costly.
At present, on market (application number be 201210243615.8 Chinese patent disclose a kind of gear), it comprises teeth groove, endoporus, oil duct, oilhole, wheel body and through hole, oil duct is provided with between teeth groove and endoporus, oil duct one end is provided with oilhole, wheel body is provided with through hole, filled with foam aluminum thing is filled with in through hole, but this gear oil with oil-filling device is very large, can not continue to continue repairing in the process engaged at gear, still manual repairing is needed, and oil duct oil storage capacity is poor, still be easy to produce oil dripping, no matter so be direct manual repairing mode comparatively common on market, or this repairing mode by oil duct of foregoing invention, in fact still lower to the utilization ratio of gear oil, both gear oil was wasted, repairing effect is also not too obvious.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide described inside of taking turns body to be provided with oil storage cavity, the sidewall of the described gear teeth is provided with oil outlet, be provided with the Fuel Tanking Unit for preventing the too fast outflow of described oil storage cavity internal gear oil in described oil outlet, described Fuel Tanking Unit and oil storage cavity are all connected by oil road.
So, gear oil can be injected oil storage cavity by oil inlet hole and flow into oil road, when gear does not carry out transmission engagement, oil road is due to Fuel Tanking Unit inhibition, gear oil can not be flowed out from oil outlet, transmission engagement is carried out once gear, the tangential force be subject to due to the gear teeth is applied on Fuel Tanking Unit, oil outlet oozes out with regard to having a small amount of gear oil, infiltrate on gears meshing sidewall, thus play an effect of refueling, so, each volume read-out is less, and gear oil can be made to be seeped into whole sidewall, substantially increase the utilization ratio of gear oil.
The utility model can be set to further: described oil storage cavity shape is hollow ring, and described oil road is uniformly distributed around the side surface stating oil storage cavity.
Oil storage cavity and oil road arrange like this and can make whole gear symmetrically structure, stressed more even in the process of transmission engagement, increase the working life of the utility model gear.
The utility model can be set to further: described Fuel Tanking Unit comprises, damping hole is provided with away from one end of oil storage cavity at described oil road, the described damping hole the other end is provided with cylinder cavity volume, and described cylinder cavity volume two ends are connected with the oil outlet being arranged on gear teeth sidewall two ends respectively.
By the setting of damping hole and cylinder cavity volume, fluid slowly can only be oozed out from damping hole, one can be played and well store oil effect, prevent that fluid is too fast to ooze out.
The utility model can be set to further: described cylinder cavity volume inside and gear teeth sidewall are equipped with oil absorption material, and full cylinder cavity volume filled by described oil absorption material, and is laid on the sidewall surfaces of gear.
By the setting of oil absorption material, when gear stationary, gear teeth sidewall does not have tangential force extrude oil absorption material, oil absorption material keeps diastole state, the gear oil absorbed from oil road from damping hole in oil absorption material body can not be extruded, once gear starts transmission engagement, the gear teeth are subject to the effect of tangential force, extruding oil absorption material, the gear oil stored in oil absorption material is originally saturation state, being squeezed to spill into is in contact with it on meshed gears gear teeth sidewall, after engagement, the gear teeth of two gears are separated, oil absorption material is diastole again, from the gear oil in oil road by being absorbed in the cotton body of oil absorption material by damping hole by gear, so just complete the oiling process of gear teeth, the oiling of all gear teeth just can be completed according to above-mentioned principle.
In one embodiment, described oil absorption material can be set to sponge, and sponge material is comparatively common, and it is good and saved economy to store functional oil.
In one embodiment, described oil absorption material can be set to cellucotton, and it is less that the air gap of cellucotton compares sponge, and in the process of engagement, fluid is easier to flow out from cellucotton, and compared to the mode arranging sponge, oil pump capacity is larger.
The utility model can be set to further: above-mentioned body side surface of taking turns is provided with oil inlet hole, and described oil storage cavity is connected by oil input channel with described oil inlet hole, and oil inlet hole is provided with cork.
Be finished once oil storage cavity internal gear oil, can also extract cork, then note in oil storage cavity by oil hole by oil, general frequency of utilization is not high, within general about one month, need refuel once in oil storage cavity.
Compared with prior art, the utility model has the advantage of: ensure that and do not carry out repairing when gear does not carry out engaging, and gear oil can be made in the process of engagement driving to cover by the side surface of repairing gear tooth for engaging to greatest extent, improve the utilization ratio of gear oil to greatest extent, and structure is simple, service time for a long time and manually easy to lubricate.
