Actively spiral bevel gear
This utility model relates to gear technique field, specifically, is a kind of actively spiral bevel gear.
The version of gear is varied, of a great variety, as a kind of common power transmission mode, is widely used in the every field in production, life.
In existing machine driving, gear many employings ferrous materials is made, and causes that gear is comparatively heavy, in installation and removal process, it is often necessary to multi agent cooperation, could be dismounted by gear；When carrying out gear installation, it is impossible to firmly install, when dismantling, it is impossible to gear is taken out smoothly, and there is potential safety hazard, in transmission process, owing to torsion is excessive, cause wheel shaft portion to deform, affect equipment properly functioning.
Utility model content
In order to solve the problems referred to above, the utility model proposes a kind of actively spiral bevel gear, existing gear is done certain improvement, when overcoming gear to install, unstable situation is installed, and makes gear disassembling convenient, strengthen the mechanical strength in gear hub portion, make transmission process is not susceptible to deformation, improve the reliability of equipment.
For reaching above-mentioned purpose, the concrete technical scheme that this utility model adopts is as follows:
A kind of actively spiral bevel gear, including wheel teeth portion, wheel shaft portion, spline part and threaded shank have been sequentially connected with it at the described bigger diameter end taking turns teeth portion, it is connected to bearing construction section at the described miner diameter end taking turns teeth portion, it is provided with the shaft shoulder for coordinating with bearing inner race described wheel between teeth portion with described bearing construction section, is laid with at least two kerve at the described shaft shoulder near the end of described bearing construction section.
Further describing, described teeth portion of taking turns is spiral bevel gear, and this anglec of rotation taking turns teeth portion is left-handed 45 degree to 50 degree.
Further describing, the spline of described spline part is involute spline.
Further describe, more firm in order to make gear be mounted so as to, the periphery wall of described threaded shank is additionally provided with at least 6 locking pin-and-holes so that staff can low-angle ground swing pinion, what make that gear installs is more firm.
Further describing, in order to make readily accessible gear, a notch of described kerve is arranged on the periphery wall of the described shaft shoulder, and another notch of described kerve is arranged on the periphery wall of described bearing construction section.
The beneficial effects of the utility model: by arranging multiple locking pin-and-hole on gear, staff can low-angle ground swing pinion, make gear be more firmly mounted and convenient, owing to being provided with spline, the wheel shaft portion intensity making gear is big, is unlikely to deform, improves mechanical efficiency, extend service life, gear arranges kerve, when gear disassembling, it is possible to by kerve, bearing is dismantled, convenient disassembly, it is to avoid damage to bearing.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, this utility model is further illustrated.
Fig. 1 is structural representation of the present utility model；
In figure, 1. take turns teeth portion, 2. wheel shaft portion, 3. spline part, 4. threaded shank, 5. bearing construction section, 6. the shaft shoulder, 7. kerve, 8. locking pin-and-hole.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model and operation principle are described in further detail.
As can be seen from Figure 1: a kind of actively spiral bevel gear, including wheel teeth portion 1, bigger diameter end in wheel teeth portion 1 has been sequentially connected with wheel shaft portion 2, spline part 3 and threaded shank 4, miner diameter end in wheel teeth portion 1 is connected to bearing construction section 5, between wheel teeth portion 1 and bearing construction section 5, it is provided with the shaft shoulder 6 for coordinating with bearing inner race, is laid with at least two kerve 7 at the shaft shoulder 6 near the end of bearing construction section 5.
As can be seen from Figure 1: the spline of spline part 3 is involute spline；Wheel teeth portion 1 is spiral bevel gear；The periphery wall of threaded shank 4 is additionally provided with at least 6 locking pin-and-holes 8；One notch of kerve 7 is arranged on the periphery wall of the shaft shoulder 6, and another notch of kerve 7 is arranged on the periphery wall of bearing construction section 5.
In the present embodiment, the anglec of rotation taking turns teeth portion 1 is left-handed 45 degree to 50 degree.
