Abstract

The utility model provides a kind of encoder coupler, including body, body has the connection end one for being connected with encoder and the connection end two for being connected with motor shaft, it is characterized in that, connection end one includes three pawls for being formed with gap each other, the top of each pawl is even surface, and the root of each pawl is formed with external screw thread, and tapered jacket, which is enclosed on outside connection end one, makes three pawl clampings.The utility model is simple in construction, simple operation, can realize that bore is adjustable, and effectively eliminates the skidding between shaft coupling and axle, the need for meeting in actual production.

Description

Encoder coupler

Technical field

The utility model is related to a kind of shaft coupling, especially a kind of encoder coupler.

Background technology

Existing encoder coupler is usually fixed bore, and makes to be screwed when connecting.Such a shaft coupling should With existing defects on the encoder.Production when, motor shaft is typically not in problem, but selected encoder application when with The situation that perfect condition has deviation and need to change encoder happens occasionally.Because the bore of encoder coupler is fixed, during selection and Encoder is changed together can cause unnecessary loss, do not change and can produce many restrictions to the selection of encoder.

Further, since using screw to fix, when tightening, screw can cause certain damage to the surface of axle, day accumulate the moon It is tired the performance of axle to be affected greatly.Also, screw contact surface very little, easily skids in torque fluctuations, or when larger, Influence actual use.

The content of the invention

The technical problems to be solved in the utility model is：Realize that one end bore can on the basis of original encoder coupler Adjust.

In order to solve the above-mentioned technical problem, the technical solution of the utility model there is provided a kind of encoder coupler, bag Body is included, body has the connection end one for being connected with encoder and the connection end two for being connected with motor shaft, its feature It is, connection end one includes three pawls for being formed with gap each other, and the top of each pawl is even surface, the root of each pawl External screw thread is formed with, tapered jacket, which is enclosed on outside connection end one, makes three pawl clampings.

Preferably, the headstage ground edge formation step of each pawl.

Preferably, the inwall of the tapered jacket connected by a circle cylindrical female face and the smooth conical surface of circle and Into cylindrical female face is engaged with the external screw thread.

The utility model is simple in construction, simple operation, can realize that bore is adjustable, and effectively eliminates shaft coupling and axle Between skidding, the need for meeting in actual production.

Embodiment

With reference to specific embodiment, the utility model is expanded on further.It should be understood that these embodiments are merely to illustrate this Utility model rather than limitation scope of the present utility model.In addition, it is to be understood that reading the content of the utility model instruction Afterwards, those skilled in the art can make various changes or modifications to the utility model, and these equivalent form of values equally fall within this Shen Please appended claims limited range.

With reference to Fig. 1 and Fig. 2, a kind of encoder coupler that the utility model is provided, including body, body have be used for The connected connection end one of encoder and the connection end two for being connected with motor shaft, connection end one is formed each other including three There is the pawl 1 in gap, the top of each pawl 1 is even surface, and the headstage ground edge of each pawl 1 forms step.The root of each pawl 1 Portion is formed with external screw thread 2.Tapered jacket 3, which is enclosed on outside connection end one, clamps three pawls 1.

With reference to Fig. 3, the inwall of tapered jacket 3 is connected by a circle triangle inner threaded surface 3-1 and the smooth conical surface 3-2 of a circle Form, cylindrical female face 3-1 is engaged with external screw thread 2.

Connection end one of the present utility model is by three pawls 1 and fixed connection shaft, because three pawls 1 are captured to axle, Contact surface is greatly increased, so effectively reducing the generation of skidding, and also increases the torsion achieved by shaft coupling Square.Also, the utility model is clamped action using tapered jacket 3, because the presence of tapered jacket 3, realizing bore can Adjust, be adapted to the change of connection shaft size in certain limit.The threaded portion of tapered jacket 3 has used the triangle spiral shell with self-locking Line, it is possible to prevente effectively from de- pine occurs in use.
