Abstract
The utility model belongs to the technical field of gears, relating to a bevel wheel; an external cylindrical face of a hollow cylinder is provided with a ring of helical teeth, and one side of the internal cylindrical face thereof is provided with an annular convex ring for limiting the position of an external ring of a bearing; and both the annular convex ring and hollow cylinder form an integral structure. The bevel wheel has the advantages of long service life, accurate position limiting to the bearing in the bevel wheel and no abrasion easily, and is applicable to various types of bevel wheels.
Description
Technical field
The utility model belongs to the gear technique field, refers in particular to a kind of helical gear.
Background technique
There is not bulge loop on the existing general helical gear inner ring, dress bearing and come to bearing outer ring spacingly with packing ring on the helical gear inner ring, packing ring is shifted easily, causes bearing spacing inaccurate, causes that helical gear weares and teares easily, working life short.
Summary of the invention
The purpose of this utility model provides a kind of long service life, at a kind of helical gear spacing accurately to the helical gear inner bearing, that be not easy to wear and tear.
The purpose of this utility model is achieved in that
Helical gear, the external cylindrical surface of hollow cylinder are provided with a circle helical teeth, are provided with the annular convex ring spacing to bearing outer ring in a side of hollow cylinder inner cylindrical surface.
Above-mentioned annular convex ring and hollow cylinder are integral structure.
The outstanding compared to existing technology advantage of the utility model is:
The utility model is provided with the annular convex ring spacing to bearing outer ring in a side of hollow cylinder inner cylindrical surface, and is spacing accurately to bearing, makes helical gear be not easy wearing and tearing, long service life.
Description of drawings
Fig. 1 is a perspective view of the present utility model.
Embodiment
The utility model is further described with specific embodiment below in conjunction with accompanying drawing, referring to Fig. 1:
Helical gear, the external cylindrical surface of hollow cylinder 10 are provided with a circle helical teeth 12, are provided with the annular convex ring 11 spacing to bearing outer ring in a side of hollow cylinder 10 inner cylindrical surfaces.
Above-mentioned annular convex ring 11 is an integral structure with hollow cylinder 10.
The foregoing description only is one of preferred embodiment of the present utility model; be not to limit protection domain of the present utility model according to this; so: all equivalences of doing according to structure of the present utility model, shape, principle change, and all should be covered by within the protection domain of the present utility model.
Claims (2)
1. helical gear, the external cylindrical surface of hollow cylinder are provided with a circle helical teeth, and it is characterized in that: the side at the hollow cylinder inner cylindrical surface is provided with the annular convex ring spacing to bearing outer ring.
2. helical gear according to claim 1 is characterized in that: described annular convex ring and hollow cylinder are integral structure.
