Description

Short structure external double-diaphragm type coupling

Technical Field

The utility model relates to a diaphragm formula shaft coupling technical field specifically is the external double diaphragm formula shaft coupling of short structure.

Background

The coupler is an important component in a mechanical transmission system, is a device for connecting two shafts to rotate together without disengaging in the process of transmitting torque and moving, is widely applied to transmission shafting of mechanical products such as heavy machinery, metallurgical machinery, mining machinery, engineering machinery, agricultural machinery, petroleum machinery, hoisting machinery, ships, machine tools, water pumps, speed reducers and the like, consists of rigid elements, and is suitable for occasions with very small allowable relative displacement of the two shafts. The coupler has the advantages of simple structure, small volume and low cost. Rigid couplings include flange couplings, sleeve couplings and the like, and flexible couplings are widely applied because rigid couplings have high requirements on coaxiality of two shafts.

SUMMERY OF THE UTILITY MODEL

In view of the problem that exists among the prior art, the utility model discloses an external double diaphragm formula shaft coupling of short structure, the technical scheme of adoption is, including the whole diaphragm group of spacer bush and bush formula, its characterized in that: install first half-coupling and second half-coupling in the spacer sleeve, the position of first half-coupling and the position of second half-coupling are corresponding and the contact is connected, the quantity of the whole diaphragm group of bush formula is two, and two whole diaphragm groups of bush formula are connected with first half-coupling and second half-coupling contact respectively, all be equipped with threaded connection hole on whole diaphragm group of bush formula, first half-coupling, second half-coupling and the spacer sleeve, threaded connection has the reamed hole bolt.

As a preferred technical solution of the present invention, the bushing-type integral diaphragm group is located outside the flanges of the first half-coupling and the second half-coupling.

As an optimal technical scheme of the utility model, all be equipped with the keyway in first half-coupling and the second half-coupling.

As an optimized technical scheme of the utility model, the whole diaphragm group of bush formula is that the stainless steel elasticity diaphragm that many monolithic thickness is 0.5mm piles up and forms.

The utility model has the advantages that: the utility model discloses the whole diaphragm formula shaft coupling of bush is flexible coupling, the great axial skew function of compensation has, can solve the permissible relative displacement volume very little state of rigid coupling diaxon line, can solve original riveting formula diaphragm in addition and compress tightly untimely, insecure, shortcoming such as fragile increases diaphragm intensity and life, the great axial skew function of compensation has, high durability and convenient installation, and can change diaphragm and bolt under the condition of unmovable equipment, the specially adapted equipment spindle nose is apart from very short use occasion.
