Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As Fig. 1~shown in Figure 7, cross-axle universal shaft coupling of the present utility model cross bag, comprise the cross axis body 1 and intermediate 2 that are set to one, on cross axis body 1, be combined with bearing 3, attachment portion between cross axis body 1 and the intermediate 2 adopts rounding off part 4 rounding ofves to be connected, and at the outer surface of rounding off part 4 protective ring 6 that is used to seal the location is housed.By adopting rounding off between cross axis body 1 and the intermediate 2, improved the present situation that cross axle adopts cylinder boss stress to concentrate, and then cross axle intensity and bearing capacity have been improved, and the protective ring 6 that is provided with can play the positioning action to bearing 3, avoids bearing 3 on cross axis body 1 play to take place.In this embodiment, also can adopt in the joint of cross axis body 1 and intermediate 2 and realize with modes such as the form of chamfering seamlessly transit.
For after adopting rounding off between cross axis body 1 and the intermediate 2, can effectively locate in the axial direction bearing and Sealing, fixedly install joining plate 5 at the outer surface of intermediate 2, protective ring 6 is fixedlyed connected with joining plate 5.Protective ring 6 is fixedlyed connected with joining plate 5, thereby make protective ring 6 fix, can prevent further that bearing 3 from cross axis body 1 play taking place at the axial direction of cross axis body 1.And fixedly connected forms such as can adopting clamping, riveted joint between protective ring 6 and the joining plate 5, as preferred mode, adopt between protective ring 6 and the joining plate 5 to be threaded.
In order to play good sealing effect to bearing 3, the end that is positioned at rounding off part 4 places at bearing 3 is provided with the compound seal of being made up of mulit-lip seal ring 10, J type outside framework oil seal circle 11 and O RunddichtringO 12.By the compound seal of forming by mulit-lip seal ring 10, J type outside framework oil seal circle 11 and O RunddichtringO 12 that is provided with, can play fine sealing effect to bearing 3, can stop impurity such as moisture and scale to enter bearing 3 along the cross axle surface effectively, be beneficial to the discharge of old grease and the injection of new grease, make bearing 3 can obtain good lubricating.The end face that mulit-lip seal ring 10, J type outside framework oil seal circle 11 and O RunddichtringO 12 are arranged on bearing 3 can play effective seal and get final product, as preferred mode, mulit-lip seal ring 10 is fixedly installed on the bearing outer ring end face and forms sealing with the outer surface of protective ring 6; J-shaped outside framework oil seal circle 11 is arranged between bearing outer ring and the protective ring 6 and forms sealing with the outer surface of protective ring 6; O-ring seals 12 is arranged between protective ring 6 and the cross axis body 1, and forms sealing with the internal surface of protective ring 6 and the outer surface of cross axis body 1.After compound seal being adopted this mode make up, can more effectively play sealing effect.
Bearing 3 can be to adopt sliding bearing, also can be to adopt rolling bearing, and preferred rolling bearing.As preferred mode, described rolling bearing is no inner ring rolling bearing, and rolling element is made of multiple row cylindrical roller 13, and the internal surface port that is positioned at rounding off part 4 places at bearing outer ring is provided with elastic adjusting strip 7 and circlip 8.Be set to not have the inner ring rolling bearing by rolling bearing, make the diameter of axle of cross axis body 1 increase, cylindrical roller 13 diameters increase.And the elastic adjusting strip 7 and circlip 8 that are provided with both be beneficial to and had improved the stressed of cylindrical roller 13, had improved the manufacturability of bearing outer ring structure again and had guaranteed roller bearing axial internal clearance stability.
For the metal fillings that produces takes place to grind in the end that can effectively prevent bearing outer ring and cross axis body 1 bearing 3 is caused adverse effect, the end that is positioned at cross axis body 1 at bearing outer ring is provided with axial internal clearance spacer 9.The nonmetal selflubricating cross axle axial internal clearance spacer that axial internal clearance spacer 9 preferably adopts is in light weight, friction factor is little, but effectively lubricating, prevent to grind wound, improve the working life of bearing 3.
