Abstract
The utility model relates to a telescopic cross axle type universal joint who uses usually on the rolling mill of metallurgical industry, conticaster especially relates to the improvement of outer integral key shaft and the lubricated mode of internal spline cover on this shaft coupling. The utility model is realized by processing continuous oil lines on the surface of the external spline shaft and radially arranging an oil inlet and an oil outlet; meanwhile, an oil delivery hole is axially formed in the center of the end face of one side of the shaft, and the oil inlet hole and the oil outlet hole are communicated with the oil delivery hole; one end of the oil transmission hole is a blind hole, and the other end of the oil transmission hole is blocked by a cylindrical block. The utility model realizes the long-term lubrication of the external spline shaft and the internal spline housing, and prolongs the service life of the universal coupling; convenient to use, save lubricating oil.
Description
Technical field the utility model relates to a kind of universal coupling with spider, relates in particular to the improvement of male splined shaft and inner spline housing lubricating system on this coupling.
Background technique is present, and the rolling mill of metallurgy industry, casting machine use telescopic universal coupling with spider transmitting torque usually.Universal coupling with spider is made up of two cross shaft coupling heads, male splined shaft, inner spline housing, connecting tube, sleeve, seal ring and lubricating cups.One end of male splined shaft is welded on the cross shaft coupling head; The one end welding of inner spline housing and connecting tube, the other end of connecting tube is welded on another cross shaft coupling head again; On male splined shaft and inner spline housing, process involute splines, undertaken by them meshing, thereby realize the not transmission of moment of torsion between the equipment on same the straight line of diaxon; The effect of sleeve, seal ring and connecting tube is that drive part is sealed, and connecting tube prolongs the effect of coupling axial length in addition; Lubricating cup is used for splendid attire lubricant oil.Now, the lubricating system of male splined shaft and inner spline housing is to add lubricating cup on connecting tube, the lubricant oil that injects along lubricating cup all enters in the tube chamber of connecting tube, because tube chamber is bigger, be not easy to fill with fully, so lubricant oil can't enter the meshing position between male splined shaft and the inner spline housing smoothly, can not guarantee the long-term lubricated of splined section, reduced the working life of coupling, and big with oil mass, and seepage is serious.
Summary of the invention invention the purpose of this utility model is to provide a kind of universal coupling with spider with semi-automatic mode oiling, makes the involute splines of male splined shaft and inner spline housing obtain lubricating for a long time, and the fuel-economizing leakproof.
Implementation of the present utility model is: at the continuous oily line of the surface Machining of male splined shaft, and radially offer oil inlet hole and oil outlet; Simultaneously at this a side end face central shaft to offering the oil transportation hole, and oil inlet hole and oil outlet are communicated with the oil transportation hole; One end in oil transportation hole is a blind hole, the other end garden post piece shutoff.
For making lubricant oil be covered with whole splined section smoothly along oily line, can be certain angle between the oily line of processing and the axial line, the span of angle is: 50 °＜θ＜70 °;
For making lubricant oil in oil outlet flows into the groove of oily line smoothly, oil outlet and oily line are intersected.
The utility model has been realized the long-term lubricated of male splined shaft and inner spline housing, has prolonged the working life of Hooks coupling universal coupling; Easy to use, save lubricant oil.
Description of drawings Fig. 1 is a structural representation of the present utility model.
The utility model is described in further detail below in conjunction with accompanying drawing for embodiment.
Embodiment 1: semi-automatic oiling Hooks coupling universal coupling described in the utility model is made up of lubricating cup 1, male splined shaft 2, sleeve pipe 3, inner spline housing 4, seal ring 5, connecting tube 6 and cross shaft coupling head 7.It is as follows to implement a preferred embodiment of the present utility model: process continuous oily line 12 at the cylindrical of male splined shaft 2, angle theta=60 of oily line 12 and axial line °; End face center drill diameter at male splined shaft 2 close cross shaft coupling heads is the oil transportation hole 10 of φ 10mm, and an end in this hole blocks up weldering with cylinder bloom 8, and the other end is a blind hole; On male splined shaft 2, radially bore φ 10mm oil inlet hole 9 and φ 10mm oil outlet 11, their oil transportation holes 10 are communicated with; Oil inlet hole 9 is connected with lubricating cup 1; Oil outlet 11 intersects with oily line 12.
During use, the gasoline pump oil nozzle is aimed at lubricating cup 1 add lubricant oil, lubricant oil flows into oil transportation hole 10 through oil inlet hole 9, flows in the groove of oily line 12 through oil outlet 11 again, and realization male splined shaft 2 is lubricated with inner spline housing 4.
