Technological scheme: a kind of sliding loader wheel limit transmission device, comprise wheel limit bearing, wheel limit axle, tapered roller bearing, oil sealing and sprocket wheel, described axle one end, limit of taking turns is provided with wheel rim assembly department, the other end is provided with the spline be connected with sprocket wheel, described limit bearing of taking turns is fixed on complete machine vehicle frame, described limit axle of taking turns is through taking turns limit bearing by two groups of tapered roller bearing axially locating, describedly take turns tapered roller bearing both sides between limit bearing and wheel limit axle and respectively oil sealing is installed, described take turns limit bearing and wheel limit axle and tapered roller bearing between define closed lubricating cavity by the oil sealing of both sides, describedly take turns the mounting hole for installing forced filling oil cup limit bearing radially offering and is communicated with lubricating cavity.At the lubricating cavity that wheel limit transmission device internal form one is airtight, in lubricating cavity, fill in by forced filling oil cup the independent lubricating that appropriate lubricating grease realizes both sides tapered roller bearing, improve reliability and the working life of wheel limit transmission device.
In order to ensure the tapered roller bearing sufficient lubrication of both sides, described lubricating cavity comprises oil storage cavity and lubrication channel, and the internal diameter of described oil storage cavity is the structure increased progressively to two ends by centre.Lubricating grease when taking turns limit axle and rotating in oil storage cavity throws away to the direction away from Lun Bianzhou center under centrifugal action, tubaeform due in both-side opening in oil storage cavity, thus lubricating grease is piled up to the lubrication channel of both sides, ensure that the tapered roller bearing sufficient lubrication of both sides.
In order to ensure the adjustment of tapered roller bearing axial internal clearance in process convenient for assembly simultaneously of sealing effect in lubricating cavity, described wheel on the axle of limit is provided with guide sleeve, locking gasket and locking nut successively near between the tapered roller bearing of sprocket wheel side and sprocket wheel, and described oil sealing is arranged between wheel limit bearing and guide sleeve.The error in course of working can be made up by the adjustment of locking nut, ensure that the installation dimension of oil sealing simultaneously, reduce installation difficulty and manufacture cost.
Beneficial effect: the present invention ensure that the effect of the independent lubricating of wheel transmission device both sides, limit tapered roller bearing by the setting in closed lubrication chamber, improves reliability and the working life of wheel limit transmission device; By the improvement to tapered roller bearing axial internal clearance adjust structure, improve the sealing reliability of lubricating cavity, the error in course of working can be made up simultaneously, reduce installation difficulty and manufacture cost.
