Description

Oblique axis spiral bevel fluted disc

Technical field

The utility model relates to a kind of gear, particularly a kind of oblique axial cone fluted disc.

Background technique

In prior art, there is error because spiral bevel gear adds man-hour, the design of gears meshing contact ratio is reasonable not, the reasons such as running clearance is larger, makes spiral bevel gear there will be the drift of Gear Contact district in the course of the work, the problems such as working gear noise is large.

Model utility content

In view of this, the purpose of this utility model is to provide a kind of oblique axis spiral bevel fluted disc, operationally there is the problems such as contact area drifts about, operational noise is large to solve existing spiral bevel gear.

The utility model oblique axis spiral bevel fluted disc, modulus is 4, and the number of teeth is 34, normal profile angle is 20 °, and standard pitch diameter is 136mm, reference cone angle 69.08 °, Root angle 64.73 °, pitch cone radius is 72.8mm, and helix angle is 25 °, rotary orientation is dextrorotation, and it is-0.333 that radial direction becomes coefficient, and tangentially becoming coefficient is-0.065, whole depth is 7.6mm, and crossed axis angle is 90 °, and sideshake is 0.35um, addendum coefficient is 0.85, and radial clearance coefficient is 0.2.

Further, described oblique axis spiral bevel fluted disc, its contact (area) pattern is 40 ~ 70% in tooth depth direction, and tooth length direction is 35 ~ 65%.

Further, described oblique axis spiral bevel fluted disc, its disk body has been evenly arranged mounting hole and two positioning pin holes.

Further, described oblique axis spiral bevel fluted disc, is provided with axis hole in the middle part of it, and shaft hole diameter is 65.02mm ~ 65.05mm, and fluted disc external diameter is 135.8mm ~ 136mm.

The beneficial effects of the utility model:

The utility model oblique axis spiral bevel fluted disc, its contact ratio is within the scope of 1.9-2.1, contact area is larger, load is better, operational noise is less, contact area also can better prevent comparatively greatly the problem of contact area drift in working procedure simultaneously, and its sideshake is less simultaneously, makes operational noise lower further.

Accompanying drawing explanation

Fig. 1 is the sectional structure schematic diagram of the utility model oblique axis spiral bevel fluted disc.

Embodiment

Below in conjunction with drawings and Examples, the utility model is further described.

As shown in the figure, the present embodiment oblique axis spiral bevel fluted disc, modulus is 4, the number of teeth is 34, and normal profile angle is 20 °, and standard pitch diameter is 136mm, reference cone angle 69.08 °, Root angle 64.73 °, pitch cone radius is 72.8mm, helix angle is 25 °, and rotary orientation is dextrorotation, and it is-0.333 that radial direction becomes coefficient, tangentially becoming coefficient is-0.065, and whole depth is 7.6mm, and crossed axis angle is 90 °, sideshake is 0.35um, and addendum coefficient is 0.85, and radial clearance coefficient is 0.2.

The mounting distance of the present embodiment oblique axis spiral bevel fluted disc is 35mm, is 13 with the number of teeth of the gear of its pairing.

The present embodiment oblique axis spiral bevel fluted disc, its contact ratio is within the scope of 1.9-2.1, contact area is larger, load is better, operational noise is less, contact area also can better prevent comparatively greatly the problem of contact area drift in working procedure simultaneously, and its sideshake is less simultaneously, makes operational noise lower further.

The present embodiment oblique axis spiral bevel fluted disc, its contact (area) pattern is 40 ~ 70% in tooth depth direction, and tooth length direction is 35 ~ 65%, and contact precision is higher, and can ensure the load transference that gear is good, drive noise is low, long service life.

The present embodiment oblique axis spiral bevel fluted disc, its disk body 1 being evenly arranged mounting hole and two positioning pin holes 2, being convenient to processing and the installation of gear by arranging positioning pin hole, can improve processing and installation precision simultaneously.

The present embodiment oblique axis spiral bevel fluted disc, is provided with axis hole 3 in the middle part of it, shaft hole diameter is 65.02mm ~ 65.05mm, and fluted disc external diameter is 135.8mm ~ 136mm.

What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
