Abstract
The utility model discloses a kind of Novel bevel gear, comprise gear mass, described gear mass is provided with some equally distributed gear teeth, groove is provided with in the bottom centre of gear mass, be arranged with at the outer of gear mass the first inclined-plane and the second inclined-plane that are obliquely installed from the bottom to top outwardly, described first inclined-plane is all connected by arc transition with between the second inclined-plane and between the second inclined-plane with gear teeth outward edge.The utility model structure is simple, reasonable in design, by arranging from the bottom to top towards the first inclined-plane and second inclined-plane of outer incline in the periphery of gear mass, the bearing capacity of gear mass is strengthened, therefore, little, the good stability of the noise that operationally produces of the utility model umbrella gear.
Description
Technical field
The utility model relates to gear technique field, more particularly, particularly relates to a kind of Novel bevel gear.
Background technique
Umbrella gear is a kind of common gear, and for the transmission between concurrent aces, its single staged transmission ratio can to 6, be up to 8 or more than, transmission efficiency is generally 0.94 ~ 0.98.Because the comparison in difference between existing umbrella gear part and part is large, the precision comparison of umbrella gear is low, and bearing capacity is more weak, cause umbrella gear noise ratio operationally larger, poor dimensional stability, thus the working life shortening umbrella gear, reduce the reliability of umbrella gear work.
Model utility content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, and when providing a kind of work, noise is little, bearing capacity strong, the Novel bevel gear of good stability.
For achieving the above object, Novel bevel gear provided by the utility model, comprise gear mass, described gear mass is provided with some equally distributed gear teeth, groove is provided with in the bottom centre of gear mass, be arranged with at the outer of gear mass the first inclined-plane and the second inclined-plane that are obliquely installed from the bottom to top outwardly, described first inclined-plane is all connected by arc transition with between the second inclined-plane and between the second inclined-plane with gear teeth outward edge.
The utility model structure is simple, reasonable in design, by arranging from the bottom to top towards the first inclined-plane and second inclined-plane of outer incline in the periphery of gear mass, the bearing capacity of gear mass is strengthened, therefore, little, the good stability of the noise that operationally produces of the utility model umbrella gear.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-gear mass; 11-first inclined-plane; 12-second inclined-plane; The 2-gear teeth; 3-groove.
Embodiment
Below in conjunction with the embodiment in accompanying drawing, the utility model is described in further detail, but do not form any restriction of the present utility model.
Consult shown in Fig. 1, a kind of Novel bevel gear provided by the utility model, comprise gear mass 1, described gear mass 1 is provided with some equally distributed gear teeth 2, groove 3 is provided with in the bottom centre of gear mass 1, the first inclined-plane 11 and the second inclined-plane 12 be obliquely installed from the bottom to top is arranged with outwardly at the outer of gear mass 1, described first inclined-plane 11 is 7 ° towards the angle [alpha] of outer incline, second inclined-plane 12 is 28 ° towards the angle beta of outer incline, and is all connected by arc transition between the first inclined-plane 11 with the second inclined-plane 12 and between the second inclined-plane 12 with the gear teeth 2 outward edge.
The utility model adopts said structure design, by arranging from the bottom to top towards the first inclined-plane and second inclined-plane of outer incline in the periphery of gear mass, the bearing capacity of gear mass is strengthened, therefore, the noise that the utility model umbrella gear operationally produces is little, good stability.
Claims (2)
