Embodiment
Fig. 2 A is the utility model clutch teeth hub embodiment's structural representation; Fig. 2 B is the structural representation of tooth hub body in Fig. 2 A; Please refer to Fig. 1 and Fig. 2, the present embodiment provides a kind of clutch teeth hub, comprises tooth hub body 11 and sun gear 12; In tooth hub body 11, be formed centrally the boss part 111 of thickness greater than other position; On boss part 111 and corresponding teeth hub body 11 centers offer be used to being installed to the central through bore 10 on transmission shaft; The internal surface of sun gear 12 and central through bore 10 is welded and fixed and is integral.
Particularly, tooth hub body 11 external frames can be rounded, and it is the curved-surface structure that is comprised of a plurality of Different Plane in the axial direction.Wherein, axially for after the clutch teeth hub is installed on transmission shaft, the length direction of transmission shaft.
The shape of the boss part 111 at tooth hub body 11 centers can be circular or other polygonal, preferably, can be the circle concentric with tooth hub body 11, the size of boss part 111 can be determined according to the cross-section size of transmission shaft, to guarantee that central through bore 10 can be positioned on boss part 111 fully, thereby make the thickness of central through bore 10 degree of depth vertically greater than tooth hub body 11 other positions.In addition, the thickness of boss part 111 can require to determine according to concrete working condition requirement and shaft orientation layout; The thickness of boss part 111 is larger, can improve more significantly the join strength between tooth hub body 11 and sun gear 12.
The clutch teeth hub that the present embodiment provides, by improving the structure of tooth hub body, make the hole depth of central through bore 10 be increased, compared with prior art, but sun gear 12 greatly increases with tooth hub body 11 area of contact, thereby, when sun gear 12 welds with tooth hub body 11, can increase weld penetration, improve the join strength between sun gear 12 and tooth hub body 11, also can not cause the waste of material and cost simultaneously.
In the above-described embodiments, please refer to Fig. 1, the outer side surface of sun gear 12 can comprise for the teeth transmission unit 121 with the engagement of other gear and not be formed with the assembly department 122 of teeth, and assembly department 120 penetrates in the central through bore 10 of tooth hub body 11 and is welded and fixed and is integral with central through bore 10 internal surfaces; Sun gear 12 centers can also offer be used to being installed to the mounting hole on transmission shaft.Wherein, the teeth that form teeth transmission unit 121 can be the straight-tooth that extends vertically, and certainly, according to concrete transmission condition needs, the teeth of helical teeth or other form also can be adopted in teeth transmission unit 121.
When welding tooth hub body 11 and sun gear 12, sun gear 12 1 ends can be extend in the central through bore 10 of tooth hub body 11, and can deviate from tooth hub body 11 a side enforcement welding operation of the teeth transmission unit 121 of sun gear, owing on tooth hub body 11, having boss part 111 (as shown in Figure 2), make weld seam 2 (as shown in Figure 1) degree of depth vertically can be larger, to obtain good weld strength.
Preferably, the thickness of boss part 111 can be than the thick 0.5～1mm in other position; For example boss part 111 thickness vertically can be 2.5mm, and at this moment, the thickness of tooth hub body 11 other positions can be 2mm.
Another embodiment of the utility model provides a kind of processing method of above-mentioned clutch teeth hub, comprising:
Step 301, punching press form the tooth hub body of even thickness, and the center of described tooth hub body has be used to being installed to the central through bore on transmission shaft; For example, can the subpunch swaging become the contour shape of the tooth hub body 11 (as shown in Figure 3A) of even thickness, then go out described central through bore thereon, or, also can be by the reasonable blanking to blank, a punching press forms the tooth hub body with central through bore.
Step 302, will be described the corresponding described central through bore of tooth hub body around bend, form 14 (as shown in Figure 3 B) of ring-type flange.
Step 303, that above-mentioned flange is carried out to pier is thick, around described central through bore, to form thickness greater than other position boss part 111 (as shown in Figure 3 C) of described tooth hub body.
Step 304, sun gear is welded to the central through bore place of above-mentioned tooth hub body.
Further, after step 303, before step 304, can also adopt the cutting mode to process the central through bore edge, to remove unnecessary corner material, improve the workpiece quality that processes.
Particularly, the size of the central through bore of the tooth hub body that processes in step 301 can be slightly larger than the final size of actual required central through bore, so that through the flange of step 302, and the pier thick (comprising cutting) of step 303 after, the final size practical requirement of the central through bore that obtains.
Finally it should be noted that: above each embodiment, only in order to the technical solution of the utility model to be described, is not intended to limit; Although with reference to aforementioned each embodiment, the utility model is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be modified to the technological scheme that aforementioned each embodiment puts down in writing, or some or all of technical characteristics wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the scope of each embodiment's technological scheme of the utility model.
