Description
Technical field
The utility model relates to a kind of bevel gear, and more particularly, it relates to a kind of drive bevel gear.
Background technique
Bevel gear is also umbrella gear, is widely used in industrial transmission device, differential for vehicles, locomotive, boats and ships, power plant, steel mill, railroad track detection etc.Retarder is a critical piece in automotive transmission, and it realizes slowing down and changing the direction of transfer of power by one group of bevel-gear sett, and wherein, gear pair comprises drive bevel gear and driven wheel of differential, and both engage each other transferring power.
At present, application number be 201320479128.1 Chinese patent disclose a kind of initiatively angular wheel, it comprises bevel gear and shaft part, its shaft part comprises axle bearing mount portion successively, for cams mounted spline part, joint, outside thread on joint, by nut, axially locating is carried out to cam, excessive by circular arc between its spline part and joint, enhance its join strength, improve gear life, but owing to being High Rotation Speed during active taper working gear, in this process, nut easily gets loose, thus cause spline place to produce displacement by the cam of nut location, affect transmission effect.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is the drive bevel gear providing a kind of cam orientation stable.
For achieving the above object, the utility model provides following technological scheme: a kind of drive bevel gear, comprise bevel gear, described bevel gear comprises conical tooth and location end face, vertically multidiameter shaft is extended with along location end face, described multidiameter shaft comprises bearing construction section, spline segment and linkage section from location end face successively to multidiameter shaft end, and the radial direction of described linkage section is provided with orthogonal cross-hole, the intersection of described cross-hole and the axis coinciding of multidiameter shaft.
Preferably, described cross-hole aperture is provided with the orifice chamfer being convenient to lead.
Preferably, described orifice chamfer is 120 °.
Preferably, the outer surface of described linkage section is provided with outside thread.
Preferably, the joint of described spline segment and linkage section is provided with transition arc.
Preferably, the diameter of described transition arc is 1.5mm.
Compared with prior art, the beneficial effects of the utility model are: the radial direction of described linkage section is provided with orthogonal cross-hole, the intersection of described cross-hole and the axis coinciding of multidiameter shaft, after cam is assigned into spline segment, cam is propped up at the sheathed limited ring of linkage section, finally again locating stud is inserted in cross-hole, locating stud conflict limited ring, prevent it from producing axial motion, adopt in this way, avoid because nut loosening causes cam orientation steady when drive bevel gear High Rotation Speed, produce the phenomenon of skew, wherein, adopt criss-cross through hole, to conflict from four direction to limited ring, ensure the stability of positioning ring, and being arranged by the axis coinciding of the intersection of cross-hole and multidiameter shaft is to allow limited ring in the uniform force of all directions, the stability that cam is installed on spline is well ensure that by the form of cross-hole.

Reference character: 1, bevel gear; 11, conical tooth; 12, end face is located; 3, multidiameter shaft; 4, bearing construction section; 5, spline segment; 6, linkage section; 7, cross-hole; 8, orifice chamfer; 9, outside thread; 10, transition arc.
Embodiment
For making the object of the utility model embodiment, technological scheme and advantage clearly, the utility model being done describe clearly and completely further below with reference to accompanying drawings.Obviously, described embodiment is section Example of the present utility model, instead of whole embodiments.Based on described embodiment of the present utility model, the every other embodiment that those of ordinary skill in the art obtain under without the need to the prerequisite of creative work, belongs to the scope of the utility model protection.
As accompanying drawing 1, 3, drive bevel gear shown in 4, comprise the bevel gear 1 for transmission torque, bevel gear 1 comprises conical tooth 11 and location end face 12, location end face 12 is for the location and installation of drive bevel gear in retarder, multidiameter shaft 3 is vertically extended with along location end face 12, multidiameter shaft 3 comprises bearing construction section 4 from location end face 12 successively to multidiameter shaft 3 end, spline segment 5 and linkage section 6, bearing peace turns Duan Shanghui cover and loads onto each bearing, and for being arranged on deceleration wherein, be convenient to freely rotating of drive bevel gear, reduce pivoting friction, improve stability, spline segment 5 is for installing cam, transferring power, linkage section 6 can be installed usually to the nut of cam limit, in the present embodiment, the radial direction of linkage section 6 is provided with orthogonal cross-hole 7, after cam being assigned into spline segment 5, nut is replaced to prop up cam with limited ring, finally again locating stud is inserted in cross-hole 7, locating stud conflict limited ring, prevent it from producing axial motion, adopt in this way, avoid because nut loosening causes cam orientation steady when active conical tooth wheel speed rotates, produce the phenomenon of skew, wherein, adopt criss-cross through hole, to conflict from four direction to limited ring, ensure the stability of positioning ring, and being arranged by the axis coinciding of the intersection of cross-hole 7 and multidiameter shaft 3 is to allow limited ring in the uniform force of all directions, the stability that cam is installed on spline is well ensure that by the form of cross-hole 7.
As shown in Figure 4, described cross-hole 7 aperture is provided with the orifice chamfer 8 being convenient to lead, and because cross-hole 7 is less, locating stud inserts inconvenience, and orifice chamfer 8 inserts in cross-hole 7 for guide jaw.
Wherein, described orifice chamfer 8 is 120 °, and the diameter in aperture is very little, only has 4mm, arranges the orifice chamfer 8 of 120 °, is more conducive to the insertion of guide jaw.
As shown in Figure 1, further outside thread 9 is set at the outer surface of linkage section 6, now change limited ring into nut, the linkage section 6 that nut screws in outside thread 9 pushes against cam, nut is better compared with the stability of limited ring axis, position limit pin being inserted cross-hole 7 props up nut again simultaneously, perfectly solves the problem that nut can loosen when drive bevel gear High Rotation Speed.
As accompanying drawing 1, shown in 2, the joint of described spline segment 5 and linkage section 6 is provided with transition arc 10, when drive bevel gear is arranged on retarder by bearing, and engage each other in operation process with passive angular wheel, owing to passing through arc transition between spline segment 5 and linkage section 6, thus the stress surface between spline segment 5 and linkage section 6 is replaced with arc surface by existing wedge angle, add the stress surface between spline segment 5 and linkage section 6, make force dispersion, strengthen the fatigue resistance of the multidiameter shaft 3 of drive bevel gear, make the multidiameter shaft 3 of drive bevel gear not easy-rupturing in operation process, thus extend the working life of drive bevel gear.Wherein, the diameter of described transition arc 10 is 1.5mm, and the diameter due to spline segment 5 is 30mm, and the diameter of linkage section 6 is 20mm, therefore the diameter of transition arc 10 is unsuitable excessive, and too small do not have effect yet, adopts 1.5mm best.
The above is only exemplary embodiment of the present utility model, but not for limiting protection domain of the present utility model, protection domain of the present utility model is determined by appended claim.
