Abstract

The utility model belongs to an encoder which is connected with a motor shaft, and relates to an improvement on a support structure, in particular to an improved encoder support. The improved encoder support comprises an extended shaft of the motor shaft which is connected with an encoder shaft through a coupling, wherein the encoder support has a stepped sleeve structure with a big end and a small end; a flange which is arranged at the big end of the stepped sleeve is fixedly connected to an end cover of a motor through a shaft bolt; a flange which is arranged at the small end of the stepped sleeve is fixedly connected to an encoder through a bolt; and the extended motor shaft and the encoder shaft which are connected with each other through the coupling are positioned in the encoder support. The improved encoder support has a compact structure and reliable performance, mounting accuracy of the encoder can be improved, influence of equipment vibration on positional accuracy can be reduced, mounting procedure is simplified, and daily maintenance and repair are facilitated.

Description

A kind of improved encoder bearing

Technical field

The utility model belongs to the encoder that is connected with motor shaft, the improvement of its seat structure, particularly a kind of improved encoder bearing.

Background technology

For transmission speed and the direction of rotation that detects motor, generally be to connect encoder at motor shaft end, the transmission speed of motor, direction of rotation and start and stop position are detected and position feedback by the encoder that is installed in motor shaft end usually, encoder with high-precision discriminating ability also has the degree of precision requirement to installing, usually the installation of encoder all has been equipped with independent bearing and has linked together with predefined sole plate, the factor affecting such as vibration that be in operation by installation accuracy and sole plate, the transient distortion phenomenon can appear in the high-precision encoder detection.

Summary of the invention

The purpose of this utility model is to provide a kind of improved encoder bearing, its compact conformation, and dependable performance can improve the installation accuracy of encoder, and the vibrations of reduction equipment are simplified installation procedure to the influence of positional precision, are convenient to ordinary maintenance and maintenance.

The purpose of this utility model is achieved in that a kind of improved encoder bearing, the prolongation axle that comprises motor shaft is connecting the encoder axle by shaft coupling, the structure of encoder bearing is the ladder bushing with big small end, the ring flange that is provided with on its big end is fixed on the end cap of motor by the axle bolt, the ring flange that is provided with on its small end is fixed on the encoder by bolt, and the motor prolongation axle and the encoder axle that connect by shaft coupling are positioned at the encoder bearing.

The utility model directly is connected with motor body, removed the sole plate of encoder, effectively shortened the installation dimension chain, simplified installation procedure, reduced the influence of equipment vibrations to greatest extent to positional precision, simultaneously and since the encoder bearing radially to reach the axial location benchmark all identical with the benchmark of motor body, strong assurance the installation accuracy of equipment.Simplified the mounting-dismounting programme of encoder, the dismounting time has shortened about 70%, has made things convenient for the ordinary maintenance and the maintenance of equipment simultaneously.

The utility model compact conformation, dependable performance has improved the installation accuracy of encoder, has reduced the influence of equipment vibrations to positional precision to greatest extent, has simplified installation procedure, is convenient to ordinary maintenance and maintenance.
