Abstract

This utility model provides multidiameter.The middle part of described spindle nose includes keyway, the bottom surface of described keyway includes several lobe arranged along described multidiameter bearing of trend, several described lobe interval is arranged, described key body is installed in described keyway and the bottom surface of described key body is towards described body, described bottom surface includes several concave parts, and described concave part is identical with described boss numbers and size is mated.This utility model multidiameter, by arranging lobe in the bottom surface of keyway, arranging concave part in the bottom surface of key body, by engaging each other of concave part and lobe, adds the stability of key body and body, thus ensure that the stable use of multidiameter.

Description

Multidiameter
[technical field]
This utility model relates to a kind of rotating shaft, more specifically, it relates to a kind of multidiameter.
[background technology]
In prior art, the kind of shaft forgings is a lot, it is both provided with keyway in the most most of rotating shafts, for installing key and being made by key to produce moment of torsion between part such as gear being arranged in rotating shaft etc. and rotating shaft, and great majority are when installing retaining element by key, owing to needs ensure that part does not slides at rotation process, this just requires that the gap between key and part is the least, i.e. there is pretightning force between part and key.
Existing structure keyway is little with the installation contact area of key, and therefore lifting surface area is little, when installing retaining element by key, exists and comes off or the unstable situation such as slip.
Therefore, it is necessary to provide a kind of new multidiameter.
[utility model content]
The deficiency existed for prior art, the purpose of this utility model is to provide a kind of multidiameter, to solve the problems referred to above.
The technical solution of the utility model is as follows:
A kind of multidiameter, described multidiameter includes body and key body, described body includes axle body, it is located at the first axle body and the second axle body of described axle body two opposed end, it is located at the first axle body first shaft shoulder away from described axle body one end, it is located at the second axle body and away from second shaft shoulder of described axle body one end and is located at first shaft shoulder spindle nose away from described axle body one end, the middle part of described spindle nose includes keyway, the bottom surface of described keyway includes several lobe arranged along described multidiameter bearing of trend, several described lobe interval is arranged, described key body is installed in described keyway and the bottom surface of described key body is towards described body, described bottom surface includes several concave parts, described concave part is identical with described boss numbers and size is mated.
Preferably, the quantity of described lobe and described concave part is two.
Preferably, also include that centre bore, described centre bore run through described body.
Preferably, the width of described concave part is more than the width 1 of described lobe.
Preferably, the diameter of described the first axle body and the second axle body is less than the diameter of axle body, more than described first shaft shoulder and the diameter of second shaft shoulder.
Preferably, described body is formed in one.
Preferably, any one during described multidiameter is structural alloy steel, bearing steel, mould steel, carbon tool steel, titanium or titanium alloy is made.
The beneficial effects of the utility model are: this utility model multidiameter by arranging lobe, arranging concave part in the bottom surface of key body in the bottom surface of keyway, by engaging each other of concave part and lobe, add the stability of key body and body, thus ensure that the stable use of multidiameter.
[accompanying drawing explanation]
Fig. 1 is the planar structure schematic diagram of this utility model multidiameter；
Fig. 2 is the cross-sectional view of this utility model multidiameter.
[detailed description of the invention]
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
Please refer to Fig. 1 and Fig. 2, the open a kind of multidiameter 1 of this utility model, described multidiameter 1 includes body and key body 10.
Described body include axle body 11, centre bore 19, the first axle body 12 being located at described 11 liang of opposed ends of axle body and the second axle body 13, be located at the first axle body 11 away from described axle body 11 one end first shaft shoulder 14, be located at the second axle body 13 and away from second shaft shoulder 15 of described axle body 11 one end and be located at first shaft shoulder 14 spindle nose 16 away from described axle body 11 one end, the middle part of described spindle nose 16 includes keyway, the bottom surface of described keyway includes several lobe 161 arranged along described multidiameter 1 bearing of trend, and several described lobe 161 interval is arranged；Described centre bore 19 runs through described body.
Described key body 10 is installed in described keyway and the bottom surface of described key body 10 is towards described body, and the bottom surface of described key body 10 includes several concave parts 101, and described concave part 101 is identical with described lobe 161 quantity and size is mated.
In the present embodiment, the quantity of described lobe 161 and described concave part 101 is two, and concrete, the width of described concave part 101 is more than the width 1 of described lobe 161；Leave the gap of 1, it is ensured that when key body is installed, the installation of shortest key body 10 and do not damage keyway.
The diameter of described the first axle body 12 and the second axle body 13 is less than the diameter of axle body 11, more than described first shaft shoulder 14 and the diameter of second shaft shoulder 15；Described body is formed in one.
Described multidiameter 1 is made for any one in structural alloy steel, bearing steel, mould steel, carbon tool steel, titanium or titanium alloy.
Above-described is only embodiment of the present utility model; it should be noted here that for the person of ordinary skill of the art, on the premise of creating design without departing from this utility model; improvement can also be made, but these belong to protection domain of the present utility model.
