Abstract
The utility model provides a kind of gear, belongs to field of mechanical technique.It solves the problems, such as that existing gear transmission structure stability is bad.This gear includes body annular in shape, there are a circle teeth on outer body wall, there is the connecting portion for being cylindrical in shape protrusion on one of end face of body, connecting portion and body are coaxially disposed, there is external splines, the inner wall of body and the inner wall of connecting portion are tapered mounting surface, pass through cylindrical surface transition between two mounting surfaces on connecting portion, the diameter for the mounting surface being located within the body is gradually reduced from body to connecting portion direction, center symmetric setting of two mounting surfaces along cylindrical surface.This gear has the advantages that transmission stability can be improved.
Description
Technical field
The utility model belongs to field of mechanical technique, is related to a kind of gear.
Background technology
Gear refers to have gear continuously to engage the mechanical organ for transmitting movement and power on wheel rim.To adapt to different works
Condition, the not nearly enough use of common master gear, so, people have invented nonstandard gear.
The nonstandard gear of one of which sold on the market includes body annular in shape, and has a circle on the lateral wall of body
Teeth, have tubular lobes on the end face of body, and external splines is provided with protrusion.During installation, driving sleeve is in protrusion
And both are by spline fitted, axis is installed with gear, and axis is connected by bearing with body, to position gear.
Above-mentioned gear has a problem that：In transmission process, it may appear that axial float, and in above-mentioned gear,
The inner wall of body is a shiny surface, causes bearing to there is mobile trend, the stability that gear is positioned is influenced, so as to influence whole
The stability and precision of a transmission.
Utility model content
The purpose of this utility model is that there are the above problem for existing technology, it is proposed that a kind of gear, the skill of solution
Art problem is how to improve transmission stability.
The purpose of this utility model can be realized by following technical proposal：A kind of gear, including body annular in shape, and
There are a circle teeth, it is characterised in that convex with being cylindrical in shape on one of end face of the body on the lateral wall of body
The connecting portion gone out, and connecting portion and body are coaxially disposed, has an external splines on the connecting portion, the inner wall of the body and
The inner wall of connecting portion is tapered mounting surface, by cylindrical surface transition between two mounting surfaces, the mounting surface being located within the body
Diameter be gradually reduced from body to connecting portion direction, and center symmetric setting of two mounting surfaces along cylindrical surface.
During installation, the lateral wall of bearing is in the conical surface coordinated with mounting surface, and is respectively connected with bearing in two mounting surfaces, to add
The locating effect of strong body, so as to improve gear drive stability.
Center symmetric setting of two mounting surfaces along cylindrical surface, makes the direction of the movement tendency of two bearings on the contrary, so as to play
The effect mutually limited, come the stability for improving bearing, axis is connected with gear three so that strengthen gear rotation stability and
Precision.
In above-mentioned gear, the external splines offers annular in shape and for storing lubrication on one section away from body
The oil storage tank of grease, and the oil storage tank is coaxially disposed with body.
In above-mentioned gear, the taper of the mounting surface is 20 degree~30 degree.
In above-mentioned gear, the taper of the mounting surface is 22.6 degree.
In above-mentioned gear, the connecting portion and body are an integral structure.
Compared with prior art, this gear makes two bearings by designing center symmetric setting of two mounting surfaces along cylindrical surface
Movement tendency direction on the contrary, so as to playing the effect mutually limited, come the stabilization for improving bearing, axis is connected with gear three
Property, so as to strengthen the stability of gear rotation.

Embodiment
It is specific embodiment of the utility model and with reference to attached drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these embodiments.
As shown in Figure 1, this gear includes body 1 annular in shape, and there is a circle teeth 1a on the lateral wall of body 1.This
There is the connecting portion 2 for being cylindrical in shape protrusion, connecting portion 2 and body 1 are coaxially disposed and both are integrated on one of end face of body 1
Formula structure.
There is external splines 2a, external splines 2a offers annular in shape and for storing on one section away from body 1 on connecting portion 2
The oil storage tank 2b of lubricant grease, and preferably oil storage tank 2b is coaxially disposed with body 1.The inner wall of body 1 and the inner wall of connecting portion 2 are equal
For tapered mounting surface 3, pass through 4 transition of cylindrical surface between two mounting surfaces 3, at this time, diameter and the mounting surface 3 on cylindrical surface 4
Minimum diameter is equal.The diameter of mounting surface 3 in body 1 is gradually reduced from body 1 to 2 direction of connecting portion, and two installations
Center symmetric setting of the face 3 along cylindrical surface 4.
Wherein, the taper of mounting surface 3 is 20 degree~30 degree, and preferably this taper is 22.6 degree.
During installation, the lateral wall of bearing is in the conical surface coordinated with mounting surface 3, and is respectively connected with bearing in two mounting surfaces 3, with
Strengthen the locating effect of body 1, so as to improve gear drive stability.
The specific embodiments described herein are merely examples of the spirit of the present invention.The utility model institute
Described specific embodiment can be done various modifications or additions or using similar by belonging to those skilled in the art
Mode substitute, but without departing from the spirit of the present application or beyond the scope of the appended claims.
