CN2462142Y - Elastic coupling - Google Patents

Abstract

The utility model relates to an elastic coupling, which belongs to the attachments of mechanical driving devices. The utility model is composed of a group of spring seating shoes [2] which are hooked by curved hooks [1] of both ends of a compression spring, and provided with relatively larger end parts, and a spring diameter winding position smaller than the spring. In addition, the internal diameter of the spring seating shoe is provided with elliptical and oblate holes in the middle part, and the end part and the circle variation position are respectively provided with a small hole. The utility model has the advantages of simple and compact structure, easy fabrication, convenient assembly and disassembly, good manufacturability and wide purpose.

Description

Elastic coupling flexible coupling

The utility model belongs to the annex of mechanical transmission.

Dynamic power machine, the rolling grinding, the circular movement of driven by motor is mostly for positive drive, stressed generally bigger on the passive working surface, so reaction force is also bigger, it is both little to cushion leeway, and the stressed uniformity also has considerable influence, causes working surface easily impaired.

The purpose of this utility model provides a kind of hitch bar that buffer function is arranged, and makes it play a part flexible buffer when not influencing the running purpose.

A kind of elastic coupling flexible coupling, it is characterized in that one group of relative end of being caught on by pressure spring two ends hooks [1] is big slightly, spring is slightly smaller than spring around the place, footpath, is oval, oblate hole in the middle of the internal diameter, and the end has the spring pedestal [2] of an aperture to constitute with circle footpath variation place.

Also can be square or polygonal hole in the middle of this internal diameter.

When this coupling uses, insert the axle of motor within the end in the mesopore of footpath, another stomidium interpolation is gone into workpiece and is got final product, because the transmission of motor makes the on the one hand direct transmitting torque of pressure spring, be out of shape on the other hand, and the relative displacement of axle be compensated by distortion, relax and impact, alleviate vibration.Be used to wipe window glass damage degree is reduced, be used for stirring, making beating etc. and can make and run into hard thing and obtain buffering, be convenient to the discovery situation, guarantee that machine will not damage, be used for multiple occasions such as ground polishing, wall floating and all can exert all one's strength and obtain flexible buffer.

The utility model has the advantages that compact structure, simple, make easily that mounting or dismounting are convenient good and cheap, good manufacturability is of many uses.

Accompanying drawing is the structural representation of elastic coupling flexible coupling, wherein 1-hook, 2-base.

Enforcement of the present utility model is very convenient, and the cutting that flat foundry goods with holes uses more on a small quantity in the die sinking casting cylindrical is saved money laborsaving, and use is share raw metal or plastic raw material as required.

Claims (2)

1. elastic coupling flexible coupling, it is characterized in that one group of relative end of being caught on by pressure spring two ends hooks [1] is big slightly, spring is slightly smaller than spring around the place, footpath, is oval, oblate hole in the middle of the internal diameter, and the end has the spring pedestal [2] of an aperture to constitute with circle footpath variation place.

2. elastic coupling flexible coupling according to claim 1, the mesopore that it is characterized in that the base internal diameter can be square, polygonal.
