Description
Technical field
The present invention relates to a kind of jockey, particularly relate to a kind of encoder installing and connecting apparatus.
Background technology
Encoder is that signal or data are worked out, are converted to can be in order to the equipment of the signal form of communication, transmission and storage.Encoder converts the signal of telecommunication to angular displacement or straight-line displacement, and the former is called code-disc, and the latter is called yardstick.Can be divided into contact and contactless two kinds according to playback mode encoder; Can be divided into increment type and absolute type two classes according to operation principle encoder.Incremental encoder is to convert displacement to the periodic signal of telecommunication, then this signal of telecommunication is transformed into count pulse, represents the size of displacement by the number of pulse.The corresponding definite digital code in each position of absolute type encoder, therefore its indicating value is only relevant with the initial sum final position of measuring, and irrelevant with the pilot process of measuring.What the power shaft of contact encoder and the output shaft of motor accounted for significant proportion at present is to link together by shaft coupling, and the body of encoder is connected with device to be detected by the screwed hole being preset on motor fan housing.Because overall dimension, the installation dimension difference of different manufacturers encoder are larger, therefore, being connected that encoder is installed with motor designs just to have become the problem that will solve.Because encoder is arranged on flange type part, flange type part is again to realize rigidly connected by screw rod and bolt between motor fan housing, this just requires hole on encoder and the hole of motor shaft after installation, to have good axiality, this has not only increased the machining accuracy of part, but also needs the higher shaft coupling of apolegamy price in addition.Need now a kind of can be good at the adapting to encoder of various different installation dimensions and the jockey of motor badly.
Summary of the invention
Further improve as the present invention, the end face of described motor output shaft contacts with second shaft shoulder.Also be provided with the second through slot at described power transmission shaft near a side of described bellmouth.
Preferably, the length of the length of described the first through slot and described the second through slot is all greater than or equal to the length of described bellmouth.
By implement the present invention desirable following beneficial effect:
A kind of encoder installing and connecting apparatus, comprise that right-hand member is connected with the axis hole of encoder and left end extend into the power transmission shaft in the axis hole of motor output shaft, the left end portion of the axis hole of described power transmission shaft is the bellmouth that cross-sectional area reduces from left to right successively, be provided with the first through slot at described power transmission shaft near a side of described bellmouth, in described bellmouth, be provided with taper sheath, the interstitial hole of described taper sheath is internal thread hole, the first screw penetrates and is connected with described taper sheath from the right-hand member of the axis hole of described power transmission shaft, the body of encoder is connected with flexure strip, described flexure strip is connected with described motor fan housing by the louvre on motor fan housing.When connection, the shaft hole sleeve of motor output shaft is in the outside of described power transmission shaft left end portion, the right-hand member that while tightening the first screw, taper sheath can be hauled to described power transmission shaft moves, thereby taper sheath can expand outwardly bellmouth the one end that allows power transmission shaft be provided with bellmouth and also expand outwardly simultaneously, thereby the left end portion of motor output shaft and described power transmission shaft is linked together, and can ensure to be reliably connected between motor output shaft and encoder axis hole, processing and packaging technology difficulty that this greatly reduces parts, reduced cost.Because this structure is to have utilized louvres numerous on motor fan housing, so only need to select the louvre of diverse location to install for the encoder of different installation dimensions, this installation that makes encoder installing and connecting apparatus can adapt to the encoder of various different installation dimensions connects.
The right end portion of the axis hole of described power transmission shaft is internal thread hole, the left side of the axis hole of described encoder contacts with first shaft shoulder of described power transmission shaft, the second screw from the right-hand member of the axis hole of described encoder penetrate and with the screw-internal thread fit of the right end portion of described power transmission shaft.The axis hole of encoder can be pressed on first shaft shoulder to realize being connected of encoder axis hole and power transmission shaft by the second screw.The internal diameter of the right end portion of the axis hole of described power transmission shaft is greater than the external diameter of a circle of the screw terminal of described the first screw, the internal diameter of the mid portion of the axis hole of described power transmission shaft be greater than described the first screw screw rod external diameter and be less than the external diameter of a circle of the screw terminal of described the first screw.So just can realize power transmission shaft and be connected with the reliable of motor output shaft axis hole by screwing the first screw.The end face of described motor output shaft contacts with second shaft shoulder, and second shaft shoulder can carry out to motor output shaft the location of axial direction.Also be provided with the second through slot at described power transmission shaft near a side of described bellmouth, one end that the second through slot can allow power transmission shaft be provided with bellmouth is set and expands outwardly smoothly, thereby ensure that the left end portion of motor output shaft and described power transmission shaft reliably links together.Described encoder installing and connecting apparatus also comprises mounting flange, described flexure strip links together by the body of described mounting flange and described encoder, described flexure strip comprises the first installation portion, bend and the second installation portion, on described the first installation portion, be provided with first through hole corresponding with screwed hole on described mounting flange, on described the second installation portion, be provided with the second through hole corresponding with louvre on motor fan housing while installation, this structure facilitates the encoder of different size is connected reliably with motor output shaft.
