Abstract
The utility model discloses a low-vibration automatic slip compensation compound spline universal joint, which comprises an outer star wheel and a main shaft, wherein the main shaft is fixed relative to the outer star wheel. An inner star wheel, a steel ball and a retainer are arranged in the outer star wheel. The low-vibration automatic slip compensation compound spline universal joint also comprises a connecting rod. The main shaft is connected with one end of the connecting rod through a spline, wherein the connecting rod can axially slip relative to the main shaft; the other end of the connecting rod is provided with an external spline. When the tilt angle of the inner star wheel exceeds a set degree, the main shaft can do axial displacement so as to compensate the excessive tilt angle of the inner star wheel, and overloaded external forces of the outer star wheel and the retainer are effectively eliminated, thus, a universal joint transmission device is stable in running and longer in service life, and cannot easily get fatigue. Moreover, the use ratio of the whole universal joint is greatly improved.

The model utility content
Problem to be solved in the utility model is to improve to hang down the galloping that shakes automatic sliding and compensate compound spline universal joint, easy fatigue, short problem of life-span in the background technique.
In order to overcome the above problems, the utility model provides a kind of low vibrations automatic sliding to compensate compound spline universal joint, comprise out star wheel, the fixing main shaft of relative out star wheel, star-wheel, steel ball, retainer are installed in the described out star wheel, also comprise connecting rod, in it can do an end of the described connecting rod of axial slip relatively, the other end of described connecting rod is provided with external splines to described main shaft by spline joint.
The radial side of described main shaft is arranged with relatively can do the axial slip sliding bearing.
Described connecting rod 16 is provided with elastic element 12, the axial end of the internal spline that cooperates with external splines 10 is butted on elastic element 12 mutually, connecting rod 16 is hollow, be provided with adjusting bolt 17 during connecting rod 16 is hollow, adjusting bolt 17 comprises down card end and adjustable side, the card end that falls is made clamping matching with connecting rod 16, and the adjustable side stretches out in outside the connecting rod 16 and is provided with screw thread.
Described elastic element is square spring.
Described card end is made conical surface tensioner with connecting rod and is cooperated.
Low vibrations automatic sliding described in the utility model compensates compound spline universal joint, and in it can do an end of the described connecting rod of axial slip relatively, the other end of described connecting rod is provided with external splines to described main shaft by spline joint.When the star-wheel pivot angle surpasses the regulation number of degrees, it is excessive with the pivot angle of compensation star-wheel that axial displacement can occur main shaft, effectively eliminate the external force of the overburdening of out star wheel and retainer, like this, the card gear smooth running, to be not easy fatigue, life-span longer, and improved greatly the utilization ratio of whole universal joint.

Embodiment
Below in conjunction with accompanying drawing a kind of low vibrations automatic sliding of the utility model being compensated compound spline universal joint is described further.
As shown in fig. 1, the low vibrations automatic sliding of present embodiment compensates compound spline universal joint, comprise the main shaft 9 that out star wheel 6, relative out star wheel 6 are fixed, star-wheel 3, steel ball 2, retainer 4 are installed in the out star wheel 6, also comprise connecting rod 16, in it can do an end of the connecting rod 16 of axial slip relatively, the other end of connecting rod 16 is provided with external splines 10 to main shaft 9 by spline joint.In the present embodiment, packing ring 13, end cap 14, elastic element 12 are housed, adjusting bolt 17 on the described connecting rod 16.14 sealings of end cap prevent that dust and other impurities from entering the transmission part of spline joint.External splines on the connecting rod 16 connects with differential mechanism on the car, and by adjusting bolt 17, compacting elastic element 12 is regulated the gap between connecting rod 16 and differential mechanism.The internal spline that connecting rod is 16 li is connected with flanged joint 7 external spliness.Out star wheel 6 connects with flanged joint 7, and star-wheel 3, steel ball 2, retainer 4 are contained in the out star wheel 6, but both axial slip of star-wheel 3, but angle swinging again.Sliding bearing 8 whole dresses onboard, flanged joint 7 bar section cylindricals can move axially along sliding bearing 8 inner rings, when star-wheel 3 pivot angles surpass the regulation number of degrees, the external splines of flanged joint 7 will be automatically outwards mobile along the internal spline of 16 li of connecting rods, effectively eliminate the external force of the overburdening of out star wheel 6 and retainer, the card gear smooth running, to be not easy fatigue, life-span longer, like this, just improved greatly the utilization ratio of whole universal joint.
In the present embodiment, the radial side of described main shaft 9 is arranged with relatively can do axial slip sliding bearing 8.Undertaken spacingly by 8 pairs of main shafts of sliding bearing 9, it can not trembleed when high speed rotating, smooth running has further improved the performance of card gear.
In the present embodiment, described connecting rod 16 is provided with elastic element 12, the axial end of the internal spline that cooperates with external splines 10 is butted on elastic element 12 mutually, connecting rod 16 is hollow, be provided with adjusting bolt 17 during connecting rod 16 is hollow, adjusting bolt 17 comprises down card end and adjustable side, and the card end that falls is made clamping matching with connecting rod 16, and the adjustable side stretches out in outside the connecting rod 16 and is provided with screw thread.In the present embodiment, what cooperate with external splines 10 is differential mechanism, the differential mechanism shell is butted on elastic element 12 mutually, under the effect of elastic element 12, have between connecting rod 16 and the differential mechanism one away from trend, but because adjusting bolt 17 falls the card end and make clamping matching with connecting rod 16, the adjustable side stretches out in connecting rod 16 and cooperates with nut thread on the differential mechanism, so that connecting rod 16 is relative with differential mechanism fixing.Rotating nut makes its relative adjustment bolt 17 toward mobile away from falling to block end, then under the impetus of elastic element 12, differential mechanism moves away from blocking extreme direction relative to also past, on the contrary, rotating nut makes its relative adjustment bolt 17 toward moving near blocking extreme direction, under the nut effect, then overcome the elastic force of elastic element 12, differential mechanism moves near blocking extreme direction relative to past.By the nut on the rotation adjusting bolt adjustable side, regulate the axial clearance between connecting rod 16 and the differential mechanism, so that they remain on better position, further guaranteed the steady of running, improved the performance of running.In the present embodiment, described elastic element 12 is square spring.Can certainly be transformed to other elastic elements, such as common coil component spring.Described card end is made conical surface tensioner with connecting rod 16 and is cooperated, and should the mode of falling the card be a kind of of present embodiment, also can be transformed to other various modes of falling the card, does not do too much description at this.
The utility model is not limited to above embodiment and conversion.
