Preferably, second axis hole is circle, and the third axis hole is strip, and the width of third axis hole and the second axis
The diameter in hole is corresponding.
Preferably, it is spaced apart on the bearing and is equipped with multiple bolts hole.
Preferably, the 4th axis hole with swinging axle cooperation installation is offered on the bearing.
Preferably, the mandrel is made of polytetrafluoroethylene material.
Advantageous effect
The utility model has the advantages of simple structure and easy realization, including a swinging block and one can be along perpendicular to swinging blocks
The mandrel of oscillation center line direction rotation, offers the second axis hole being inserted into for axial workpiece so that axial workpiece in mandrel
Rotary centerline can the swing of swinging block effect under, in the plane perpendicular to swinging axle oscillation center line generate swing.
Aperture due to being opened in the third axis hole on swinging block corresponding to the second axis hole is more than the second axis hole, may make axial workpiece
Rotary centerline can generate swing under the rotary action of mandrel in the plane perpendicular to central axis center line.To make
The utility model can bear radial load, axial load or radially, axially simultaneous joint load, while by swing
The large angle pendulum of block and the large rotation angle of mandrel, make the utility model possess one of the more high inclination-angle than standard oscillating bearing
Kind cross-axle universal shaft bearing, inclination angle are much larger than existing standard oscillating bearing up to 45 ° or more.
