Description

Light high-speed spring coupling

The utility model relates to the elastic coupling flexible coupling that uses in a kind of mechanical transmission, particularly by two half-couplings and an elasticity in conjunction with molecular light high-speed elastic coupling flexible coupling.

Domestic production at present, the elastic coupling flexible coupling of use because the structure of its elasticity zygote causes itself and half-coupling inner chamber area of contact little, thereby makes the radial dimension increase of whole coupling profile; Next is existing this elasticity zygote structure, and its amount of deformation is little in the course of the work, and it is poor to cause coupling to absorb vibration ability, thereby cause vibrating work system is brought bad influence.

The purpose of this utility model provides a kind of light high-speed elastic coupling flexible coupling, has improved coupling and has absorbed vibration ability, has reduced its profile radial dimension.

The utility model is to realize like this, this light high-speed elastic coupling flexible coupling is made up of two half-couplings and an elasticity zygote, it is characterized in that two half-coupling inner chambers be provided with the identical interior external toothing of structure and one and this half-coupling be meshing with each other have corresponding in the elasticity zygote of external toothing.

In conjunction with following drawings and Examples, to structure of the present utility model, characteristics have further understanding.

Description of drawings:

Fig. 1 is the erection drawing of light high-speed elastic coupling flexible coupling of the present utility model;

Fig. 2 is the half sectional view of elasticity zygote among Fig. 1;

Fig. 3 is the left view of elasticity zygote among Fig. 2

Fig. 4 is the half sectional view of half-coupling among Fig. 1;

Fig. 5 is the left view of half-coupling among Fig. 1.

Below in conjunction with the description of drawings embodiment.

Two half-couplings 1,3 among Fig. 1, its inner chamber respectively have the identical interior external toothing 4(of structure and see that Fig. 5 shows), external toothing 4 respectively has 18 numbers of teeth in it, and two half-couplings 1,3 all adopt Zn-Al alloy material die cast.

Elasticity zygote 2 among Fig. 2, its inner and outer wall is made and is seen shown in Figure 3 with the intermeshing interior external toothing 5(of the interior external toothing of half-coupling 1,3), external toothing 5 respectively has 18 numbers of teeth in it, and these elasticity zygote 2 employing hardness are that 80 ° rubber is made like a tubular spare.

Its working principle: after two and half devices 1,3 and an elasticity zygote 2 assembled, the external toothing of the ring gear of zygote and two half-couplings engagement at this moment, and the ring gear of the external toothing of zygote and two half-couplings meshes.When coupling was worked, the flank of tooth of the half-coupling of drive end by interior external toothing passed to zygote with peripheral force, and the flank of tooth by external toothing in the zygote is again passed to the half-coupling of driven end with peripheral force, thus transmitting torque.Because zygote adopts this structure, the resiliently deformable that produces when transmitting torque can absorb vibration, causes transmission process steady, friction in whole speed range allowable, and noise free is the light high-speed elastic coupling flexible coupling of a desirable economy in fact.

Elastic coupling flexible coupling of the present utility model, by top illustrated embodiment, its advantage is obvious, its concrete advantage is as follows:

(1) because the half-coupling and the rubber zygote employing number of teeth are the interior external toothing Placement of 18 teeth, increased area of contact, whole coupling profile radial dimension is greatly reduced.

(2) the rubber zygote is made tubular, like this, not only can pass through the resiliently deformable vibration damping of profile of tooth, and can absorb vibration by the torsional deflection of cylindrical shell, makes whole mechanical system can obtain the better damping effect.

(3) two half-couplings adopt the Zn-Al alloy die cast, the profile accuracy height, and intensity is big, and is in light weight, thereby make maximum speed can reach 9000rpm.

Elastic coupling flexible coupling of the present utility model, its performance index are:

The normal revolution model transfers 600-9000rpm to.

Maximum delivered power is 1.2 kilowatts.

Maximum allowable axial displacement is 6mm.

Angular displacement allowable is △ α=1 °

Light high-speed coupling of the present utility model, the power that can be widely used in water pump, all kinds of oil hydraulic pump, oil hydraulic motor and light-duty machinery is imported and output.
