- FIG. 1 OA—FIG. 10E is a characteristic diagram showing spline hole deformation data of a hub unit for hub unit.
- the hub unit work 103 before forming the female spline which is a work, is mounted upward on the workpiece holder 1 and the inside 2 b of the tool 2 through the hole 3 a of the work 103 penetrates. ing.
- the workpiece 103 is fixed to the workpiece holder 1 at the lower surface of the flange 3b, which is a part remote from the caulked portion 3d.
- the tool 2 is composed of a portion with the cutting edge 2a and a straight guide portion 2b without the cutting edge 2a.
- the tool 2 faces the upper surface of the work receiving base 1 (the surface that contacts the lower surface of the flange 3b) in the direction of the arrow. Since the squareness of the tool 2 in the axial direction is set with high precision, a female spline with a good squareness based on the lower surface of the flange 3b can be machined. This is effective for hub units that require brake runout accuracy.
- Fig. 2 shows the configuration when the hub unit work 103 (also called work 103) is turned upside down. Description of each part is the same as that of FIG.
- the work 103 is received by the caulking flat portion 1a of the work receiving table 1 at the time of forming the female spline.
- the crimped flat portion 1a is processed by cutting, coining, or the like. Since the perpendicularity of the tool 2 to the upper surface of the work table 1 (the surface that comes into contact with the lower surface of the flange 3b) in the axial direction of the tool 2 is set with high precision, the perpendicularity is good with respect to the caulking flat surface 1a. Female splines can be machined.
- the female spline shaft constituting the output shaft is engaged with the female spline of the shaft 3c, and the flat portion of the constant velocity joint and the caulking flat portion 1a which are connected to the hub unit 3 are connected. Since the hit can be made in a good condition, it is effective for a work that is strictly sensitive to abnormal noise from the hit surface.
- a hole formed by cutting is formed in the shaft portion 3c of the hub 3 in the axial direction, and the outer ring 16 and the rolling element 18 are formed on the shaft portion 3c.
- inner ring elements 1 A method for semi-dry or drive roaching after the inner ring element 17 is crimped from the outer end side of the shaft portion 3c after the outer bearing of the bearing 7 is fitted and fitted will be described.
- a cylindrical hole 3a through which the tool 2 penetrates is previously formed in the hub shaft portion 3c of the work 103 by a lathe.
- the shape of the hole 3a is closer to the caulked portion 3d (from the bottom to the top in the figure).
- the shape with the larger diameter of the hole 3a, ie, caulking is closer to the caulked portion 3d
- the shape is set to be larger by the amount of deformation due to deformation and shrinkage caused by press-fitting of the inner ring element 17.
- the inner diameter of the hole 3a is reduced by caulking, so that the inner diameter of the hole 3a of the hub shaft portion 3c is equal to the outer diameter of the tool 2 (of the straight guide portion 2b). If the outer diameter is smaller, the tip of tool 2 will not fit. Conversely, if the inner diameter of the hole 3a of the hub shaft portion 3c is too large than the outer diameter of the tool 2, the concentricity of the tool 2 with respect to the hole 3a becomes poor. Therefore, in the hole 3a of the hub shaft 3c, the part that is not affected by caulking or press-fitting of the inner ring element 17 is machined concentrically by cutting. Process into a shape that does not reduce the inner diameter after tightening.
- a seal 11 is attached to the outer ring 16 of the work 103 so as to prevent chips from entering the bearing portion.
- the lip 11a of the seal 11 can be doubled by using the step portion of the inner ring element 17, and has a structure in which cutting chips are hard to enter.
- the configuration for preventing chips is not limited to this, and a removable cap (not shown) may be attached.
- the cap is attached to the work 103 before broaching, and the cap is removed after broaching. This cap is used repeatedly to remove chips.
- Caps are particularly effective for workpieces with multi-pole magnet encoders and for workpieces without seals. Even for a work with a seal, a cap may be used to prevent chips from sticking to the work itself.
- the upper chuck 4 holding the tool 2 is slowly lowered.
- the upper lid 5 opens in both the left and right directions (in the direction of the arrow), and the upper chuck 4 further descends, and as described above, the hub axle of the workpiece 103.
- the straight guide part 2b of the tool 2 enters the hole 3a of the part 3c. Accordingly, when the lower chuck 8 rises and approaches the lower lid 9 serving as the lid means, the lower lid 9 opens in both the left and right directions (in the direction of the arrow).
- the lower chuck 8 grips the lower end of the tool 2.
- the upper check 4 releases the tool 2 after confirming that the tool 2 is caught by the lower check 8.
- the oil 20 is sprayed as a mist (fog state) onto the tool 2.
- the nozzle 10 for spraying the mist onto the tool 2 is installed above the workpiece 103.
- the mist oil 20 is sprayed into the groove of the cutting edge 2a of the tool 2.
- the amount of oil is semi-dry processing of 5 cc / h or less.
- the surface of the tool 2 is sufficiently smooth, so perform dry broaching without spraying oil 20.
- no oil is used, so that no oil permeates into the work 103 and the processing environment is contaminated with oil.
- broaching is performed in a semi-dry or dry manner, there is almost no need to perform a cleaning step using, for example, a method of blowing air for the oil used in the processing, compared to a wet type. Furthermore, the removal of cutting powder is easier than in the wet method.
- the lowering speed of the lower chuck 8 that is, the cutting speed of broaching is generally 3 m / min to 8 Om / min.
- relatively high speed of 4 O m / mii! ⁇ 8 O m / min is adopted. The reason is related to the fact that the swarf deprives the heat and the tool 2 is hardly damaged.
- the tool 2 is pushed up from below at low to medium speeds and raised until it reaches the upper chuck 4.
- lower chuck 8 releases tool 2.
- the lower chuck 8 descends, and the lower lid 9 closes in the direction of the arrow.
- the upper chuck 4 holding the tool 2 rises at high speed, and the upper lid 4 closes.
- cleaning of tool 2 begins, during which another workpiece is transported. Thereafter, the operations shown in FIGS. 5 to 8 are repeated.
- the tool 2 Cleaning can be performed, and broaching after crimping can be performed without causing chips to adhere to the work 103.
- broaching may be performed with only the upper lid without the lower lid, or with only the lower lid without the upper lid.
- broaching may be performed without a lid.
- the upper chuck 4 is driven by an air cylinder, and the lower chuck 9 is driven by a mechanism combining a servomotor and a hole screw.
- the present invention is not limited to this, and the upper chuck 4 or the lower chuck 9 may be driven by hydraulic pressure.
- the female spline processing is performed by pulling the tool 2, but the female spline forming processing may be performed by pressing the tool 2.
- the moving direction of the tool 2 employs a method of moving from top to bottom, but a method of moving from bottom to top is also possible.
- the groove of the cutting edge 2a is spiral, but a tool with parallel grooves may be used. However, since the spiral groove of the tool 2 can be processed continuously, the female spline forming processing can be performed with high precision.
- the cutting amount is 5 to 50 m at one pitch from cutting edge to cutting edge. In this embodiment, the cutting amount at one pitch is set to be 10 to 30 / zm.
- Tool 2 is made of high speed steel or carbide and may be coated.
- the brush 6 is used as the cleaning means of the tool 2, but the invention is not limited to this, and a method of blowing air, a method using a cleaning liquid, or the like may be used.
- an outer ring, a rolling element, and an inner ring are attached to the shaft portion 3c 'of the hub 3'.
- the shaft 3c 'of the hub 3' is roughly roughened by a broach before the work for the hub unit is assembled.
- a method of performing finishing with a broach after caulking the inner ring element will be described. Finishing with a broach after inner ring element caulking is the same as the method described above.
- a case in which roughing is performed with a broach before caulking will be described.
- a hole 3f ' is formed in a shaft portion 3c' of a hub work 3 'by cutting.
- the hole 3 f ′ is not the same as the hole 3 a shown in FIG. 3, but is a cylindrical hole having a uniform inner diameter.
- the shrinkage due to the press fitting of the ring 12 is removed by broaching.
- a spline forming hole 3g ' is formed as shown in FIG. 9B.
- the spline forming hole 3 g ′ has a shape whose inner diameter increases as it approaches the crimping portion 3 d ′ (from the bottom to the top in the figure), that is, the crimping portion 3 d ′.
- the shape becomes larger as the value approaches', taking into account deformation due to caulking and shrinkage due to press-fitting of the inner ring element 17.
- the spline forming hole 3 g ′ having such a shape can be rough-worked, the machining allowance of finishing work by the broach after crimping can be reduced, and the tool life can be extended. Alternatively, the finishing itself by the broach can be eliminated.
- the shape of the hole 3 f ′ is contracted by press-fitting the ring 12, but the shape of the hole 3 f ′ may be contracted by partially chucking the outer diameter of the shaft portion 3 c ′.
- a washing process is required before assembling the bearing, so wet machining is used, and washing is performed after machining.
- Fig. 10A-Fig. 10E Fig. 10B is after roughing of broach (before press-fitting of inner ring element), Fig. 10C is after press-fitting of inner ring element, Fig. 10D is after caulking, and Fig. 10E is after finishing broaching.

- the vertical axis represents the axial direction of the shaft portion 3c
- the horizontal axis represents the amount of deformation. From Fig. 10B_Fig.
- the lower part of the spline forming hole 3 g swells due to the inner ring element press-fitting and crimping (especially crimping), so the deformation increases as the hub work 103 moves downward in the axial direction. You can see that.
- the shape data of the female spline shown in Fig. 1OA-Fig. is effective to determine the shape of the step B.
- the axial force of the hub unit (the force compressing the inner ring element in the axial direction) hardly changed before and after the broaching. It is reduced by several hundred kgf against an axial force of 5 to 10 tonf. The worst-case calculation results in a reduction of up to 5%.
- the encoder may be magnetized after broaching in order to prevent chips from adhering.
- a cylindrical hole is formed in a shaft portion of a hub unity work by cutting, a rolling bearing is externally fitted to the shaft portion, and an inner ring is swaged.
- a female spline is formed in the hole by processing, the female spline can be formed with high accuracy without increasing the number of steps and manufacturing costs.
