Embodiment
Fig. 2 is the bearing of a kind of embodiment of the utility model and the structural representation of bearing holder device, and Fig. 4 is the bearing shown in Figure 2 and the sectional view of bearing holder device.As shown in the figure, bearing in a kind of embodiment of the utility model and bearing holder device comprise bearing 201, bearing support 202, needle-like riveting point 203.
Bearing 201 is installed in the bearing support 202, and bearing 201 can be various suitable bearings, for example, and ball bearing, cylindrical roller bearing, circular cone roller bearing or the like.
Bearing support 202 is used for spring bearing 201, and bearing support 202 has the bearing saddle bore that holds bearing 201, is interference fit between the outer ring of described bearing saddle bore and bearing 201, so that a part of confining force to bearing 201 to be provided.
Needle-like riveting point 203 is positioned on the bearing support 202, and be positioned at the central axis of bearing support 202 distance on the circumference of predetermined radii.Described needle-like riveting point 203 is spherical pit.Needle-like riveting point 203 is positioned on the bearing support 202, is in the edge of bearing support 201 outer rings, and needle-like riveting point 203 distributes along the circumferencial direction of bearing support 202.In the utility model, needle-like riveting point 203 be shaped as spherical pit, the extrusion deformation amount of the riveting point periphery of spherical pit pattern is less, and the degree that stress is concentrated is also less, thus the possibility of crackle appears in the part of having avoided pressing.
Can produce the contraction of bearing saddle bore around the needle-like riveting point 203 owing to pressing, make bearing saddle bore and the magnitude of interference that is installed in the bearing 201 in the bearing saddle bore increase, thereby make that the confining force between bearing 201 and the bearing support 202 is bigger.Confining force can be the extruding force sum that a plurality of needle-like riveting points 203 produce.The extruding force that each needle-like riveting point 203 produces is to utilize to extrude the power result of experiment and calculate.Adopt pin type riveting cutter press before, afterwards, the difference of maximum static friction force is the confining force that riveting point provides in bearing and the mutual extrusion process of bearing support material.
Preferably, bearing in the present embodiment and bearing holder device comprise three needle-like riveting points, and three needle-like riveting points are spent evenly with 120 along the circumferencial direction of bearing support and distributed.The radial distance of needle-like riveting point and bearing support central axis (i.e. radius on the bearing support circumference) can be adjusted according to concrete application, preferably, present embodiment adopts 6204 bearings, therefore, described needle-like riveting point be positioned on the bearing support, with the central axis distance of bearing support on the circumference of 26mm.
