Abstract
The utility model discloses a kind of locking shaft couplings.It includes connecting tube and the spindle nose positioned at connecting tube both ends, the axle sleeve with internal taper hole of connecting tube being provided at both ends with for being installed to spindle nose, further include for installing the positioning sleeve between axle sleeve and spindle nose, positioning sleeve is with the endoporus coordinated with spindle nose and with the male cone (strobilus masculinus) with the cooperation of the internal taper hole of axle sleeve, the inner end of axle sleeve is provided with annular spacing groove, it is provided with annular groove on the connecting pin of spindle nose, snap ring is installed in annular groove, the outboard end of snap ring limits in annular spacing groove.Using above-mentioned structure, the shaft coupling after installation can be positioned by snap ring, thus it not only facilitates installation and can carry out reliable location by snap ring after installing, the problem of preventing spindle nose to be disengaged with connecting tube, in addition, its is reasonable in design so that dismounting is very convenient, and the auxiliary positioning bolt of setting further improves the reliability of connection.
Description
Technical field
The present invention relates to a kind of shaft coupling, specifically a kind of locking shaft coupling.
Background technology
Shaft coupling is for being attached to realize that a kind of device that torque transmits, existing shaft coupling are general to component
All include connecting tube, is mounted on the connector at connecting tube both ends, connector is fixedly mounted by connector sleeve and connecting tube, existing this
Structure is more common and application is also very extensive, although since its structure design is simple, can realize the reliable biography of power
It passs, but generally using hammer impact installation in installation process, installation trouble is dismantled then more not when being needed replacing after installation
Just, in addition, usually will appear the problem of spindle nose is disengaged with connecting tube after connection so that use reliability is poor.
Invention content
Be easy the technical problem to be solved in the present invention is to provide a kind of reasonable in design, installation and dismounting it is very quick and
The locking shaft coupling of good reliability.
In order to solve the above-mentioned technical problem, locking shaft coupling of the invention, including connecting tube and be located at connecting tube both ends
Spindle nose, the axle sleeve with internal taper hole of connecting tube being provided at both ends with for being installed to spindle nose, further includes for installing
Positioning sleeve between axle sleeve and spindle nose, positioning sleeve with the endoporus coordinated with spindle nose and with the cooperation of the internal taper hole of axle sleeve
The inner end of male cone (strobilus masculinus), axle sleeve is provided with annular spacing groove, and annular groove is provided on the connecting pin of spindle nose, is installed in annular groove
The outboard end of snap ring, snap ring limits in annular spacing groove.
The connecting pin inner end circumferential surface of the spindle nose is provided with threaded hole, and spiral shell is offered on the surface of the connecting tube
Bolt placement hole is mounted with the bolt for being screwed into threaded hole in the bolt containing slot of the connecting tube.
Counterbore is provided on the circumferential surface of the connecting tube, the bolt is located in counterbore.
The snap ring is two halves to opening structure, is fixedly mounted by fastener after snap ring pairing described in two halves.
The connecting tube is provided at both ends with flanged ends, the flanged ends connection of axle sleeve and connecting tube.
The connecting tube is stainless steel tube.
Using above-mentioned structure, due to the inner end for installing the positioning sleeve between axle sleeve and spindle nose, axle sleeve of setting
It is provided on the connecting pin of annular spacing groove and spindle nose and is provided with annular groove, it is possible thereby to by snap ring to the shaft coupling after installation
Positioned, thus not only facilitate installation and install after can carry out reliable location by snap ring, it is therefore prevented that spindle nose with connect
The problem of pipe disengages, in addition, its is reasonable in design so that dismounting is very convenient, and the auxiliary positioning bolt of setting further carries
The high reliability of connection.
