Definitions

  • the present invention relates to a bearing apparatus such as a vehicle hub unit in which a rolling bearing is mounted to a shaft body.
  • a vehicle hub unit will be described.
  • a rolling bearing is mounted to an outer periphery of a shaft body of a hub wheel.
  • a shaft end of the shaft body is bulged and deformed radially outward by rolling caulking to be a caulked portion.
  • This caulked portion is caulked to an outer end face of an inner ring of the bearing to thereby apply a pre-load to the bearing and to prevent coming off of the bearing.
  • the shaft body of the hub wheel has a hollow structure such that a drive shaft can be inserted into the shaft body.
  • an inner periphery of the shaft body has spline portions.
  • the spline portions are formed to be substantially adjacent to the caulked portion of the shaft end and to be formed long in an axial direction so as to mechanically connect the inner periphery of the shaft body and the drive shaft with necessary strength.
  • the spline portions are liable to be deformed radially inward to such a degree as to obstruct insertion of the drive shaft into the shaft body by force applied radially outward to the shaft end in caulking for forming the caulked portion.
  • the bearing apparatus of the invention includes a hollow shaft body and a rolling bearing mounted to an outer peripheral face of the shaft body; wherein a shaft end of the shaft body is deformed radially outward and caulked to an outer end face of an inner ring provided to the rolling bearing and the shaft body has on an inner peripheral face thereof a first area in which a spline portion in an axial direction is formed, a second area between a bending starting point for bending the shaft end of the shaft body radially outward and an end face of the shaft body, and a third area between the first area and the second area for suppressing deformation of the inner peripheral face of the shaft body caused by the caulking.
  • the spline portion is formed to be axially long on the inner periphery of the hollow shaft body so as to be mechanically connected to a spline portion on an outer periphery of a drive shaft, because the third area is provided between the first area and the second area, the first area does not directly receive an influence of radially outward deformation of the shaft end by caulking for forming the caulked portion. As a result, it is possible to maintain high accuracy of the spline portion and the first area is not deformed to such a degree as to obstruct insertion of the drive shaft.
  • the third area is preferably set according to the following expression (1):
  • X1 is an axial distance from a position of a caulking side end portion of the first area to the bending starting point for bending the shaft end of the shaft body radially outward
  • X2 is an axial distance from the bending starting point to a caulking side outer end face of the inner ring
  • y1 is a difference between an outside diameter and a pitch diameter of the first area
  • y2 is a difference between an outside diameter and an inside diameter of the shaft end of the shaft body.
  • FIG. 1 is a vertical sectional view of a hub unit according to the preferred embodiment of the present invention in a state before a hollow shaft of a hub wheel is caulked;
  • FIG. 2 is a vertical side sectional view of the hub unit according to the preferred embodiment of the invention in a state after the hollow shaft of the hub wheel is caulked;
  • FIG. 3 is an essential portion enlarged sectional view of spline-fitted portions of an inner periphery of a shaft body of the hub wheel and an outer periphery of a drive shaft in the hub unit;
  • FIG. 4 is an essential portion enlarged plan view of spline-fitted portions of the inner periphery of the shaft body of the hub wheel and the outer periphery of the drive shaft in the hub unit;
  • FIG. 5 is an enlarged sectional view of a periphery of an inner ring of a bearing and a shaft end of the hollow shaft in the hub unit.
  • FIGS. 1 to 5 A preferred embodiment of the present invention will be described with reference to FIGS. 1 to 5 .
  • a vehicle hub unit is taken as an example of a bearing apparatus.
  • balls and the like are not shown in FIG. 5 for ease of illustration.
  • the hub unit 10 includes a hub wheel 11 and a bearing 12 .
  • the bearing 12 is a double row angular contact ball bearing with vertex of contact angles outside of bearing as an example of a rolling bearing of a diagonal contact type.
  • the hub wheel 11 includes a flange 13 which is in a radially outward orientation and to which a wheel (not shown) is mounted and a hollow shaft 14 .
  • the bearing 12 includes one inner ring 15 fitted over a small-diameter outer peripheral face of the hollow shaft 14 and having a single race, a single outer ring 16 having two rows of races, a plurality of balls 17 disposed in two rows, and two snap cages 18 .
  • As the inner ring 15 an inner ring of a general single row angular contact ball bearing is used as it is.
  • the flange 19 is provided to an outer periphery of the outer ring 16 in the radially outward orientation.
  • a shaft end 14 a of the hollow shaft 14 is caulked to a caulking side outer end face of the inner ring 15 from the state in FIG. 1 to the state in FIG. 2. As a result of this caulking, the shaft end 14 a becomes a caulked portion.
  • the hub unit 10 is mounted between a drive shaft 20 and a shaft case 21 of a vehicle.
  • the hollow shaft 14 of the hub wheel 11 is spline-fitted over the drive shaft 20 and connected to the drive shaft 20 through a nut 22 .
  • the flange 19 of the outer ring 16 of the bearing 12 is connected to the shaft case 21 through a bolt 23 so as not to rotate.
  • a reference numeral 14 b designates a spline portion formed on an inner periphery of the hollow shaft 14 and a reference numeral 20 a designates a spline portion formed on an outer periphery of the drive shaft 20 .
  • the spline fitting is carried out.
  • a fitted state of the spline portions 14 b of the hollow shaft 14 and the spline portions 20 a of the drive shaft 20 is as shown in FIGS. 3 and 4.
  • the respective spline portions 14 b and 20 a are spaced uniformly in circumferential directions and are in involute shapes.
  • shapes of both the spline portions 14 b and 20 a are not limited to the involute shapes but may be other shapes.
  • the spline portions 14 b of the hollow shaft 14 are inclined in the circumferential direction. One sides of the spline portions 14 b in the circumferential direction are in contact with one sides of the spline portions 20 a of the drive shaft 14 in the circumferential direction while the other sides of the spline portions 14 b in the circumferential direction are in contact with the other sides of the spline portions 20 a in the circumferential direction.
  • a spline portion forming area (first area) 141 in which the spline portions 14 b are formed and a caulked portion forming area (second area) 142 in which the caulked portion 14 a is formed are formed.
  • a cushioning area (third area) 143 for suppressing deformation of the inner peripheral face of the hollow shaft 14 caused by caulking of the shaft end 14 a of the hollow shaft 14 is provided.
  • the first area 141 is an area between axially opposite end faces of the spline portions 14 b formed on the inner periphery of the hollow shaft 14 and a caulking side end face on a pitch circle line of the spline portion 14 b is defined as a caulking side end portion A of the first area 141 .
  • the second area 142 is an area from a bending starting point B of the shaft end 14 a of the hollow shaft 14 to an end face of the shaft end 14 a .
  • an inner peripheral edge portion 15 a of a caulking side outer end face of the inner ring 15 is chamfered round, e.g., with a quarter of a circumference of a radius of curvature X2 from a center O.
  • a point of intersection of a radial line from the center O and the inner peripheral edge portion 15 a is defined as the bending starting point B.
  • the third area 143 is an area between the caulking side end portion A and the bending starting point B.
  • a difference between an outside diameter Do of the hollow shaft 14 and a pitch diameter Dp of the spline portion 14 b is y1
  • a difference between the outside diameter Do and an inside diameter Di of the hollow shaft 14 is y2
  • an axial distance (corresponding to an axial length of the third area 143 ) from the caulking side end portion A of the spline portion 20 b to the bending starting point B is X1
  • an axial distance from the bending starting point B to the caulking side outer end face of the inner ring 15 is X2
  • a position of the third area 143 is set according to the following expression (1).
  • X2 is the axial distance from the bending starting point B to the caulking side outer end face of the inner ring 15 .
  • This is based on setting the axial length X1 of the third area 143 at a large value because the influence of deformation in caulking the shaft end 14 a of the hollow shaft 14 on the first area 141 becomes large when the radius of curvature of chamfering of the inner peripheral edge portion 15 a of the inner ring 15 becomes large or when a ratio between y2 and y1, i.e., a ratio between wall thicknesses of the first and second areas 141 and 142 becomes large.
  • the invention can be similarly applied to a vehicle hub unit having a hollow shaft with a bottom in an axial direction.
  • the invention can be similarly applied to a vehicle hub unit for a vehicle follower wheel.
