Description
Technical field
The present invention relates to a kind of attachment means, particularly relate to a kind of encoder installing and connecting apparatus.
Background technology
Encoder is the equipment of signal form carrying out signal or data working out, being converted to may be used to communication, transmit and store.Encoder is converted into the signal of telecommunication angular displacement or straight-line displacement, and the former is referred to as code-disc, and the latter is referred to as yardstick.Contact and contactless two kinds can be divided into according to playback mode encoder；Increment type and absolute type two class can be divided into according to operation principle encoder.Incremental encoder is that displacement is converted into 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 digital code determined in each position of absolute type encoder, therefore its indicating value is only relevant with the initial and final position measured, and unrelated with the pilot process measured.What the power shaft of contact encoder and the output shaft of motor accounted for significant proportion at present is to be linked 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.Owing to overall dimensions, the installation dimension difference of different manufacturers encoder are relatively big, therefore, what encoder was installed with motor connects the problem that design has just become to be solved.Owing to 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 that the hole of the hole on encoder and motor shaft has preferable axiality after mounting, this not only adds the machining accuracy of part, but also need the shaft coupling that additionally apolegamy price is higher.Need now the attachment means of a kind of encoder that can be good at adapting to various different installation dimension and motor badly.
Summary of the invention
Further improve as the present invention, the end face of described motor output shaft and the contact of second shaft shoulder.It is additionally provided with the second through slot near the side of described bellmouth at described power transmission shaft.
Preferably, the length of described first through slot and the length of described second through slot is all higher 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, it is connected with the axis hole of encoder including right-hand member and power transmission shaft that left end extend 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 is sequentially reduced from left to right, at described power transmission shaft, the side of described bellmouth is provided with the first through slot, it is provided with taper sheath in described bellmouth, the interstitial hole of described taper sheath is internal thread hole, first screw penetrates from the right-hand member of the axis hole of described power transmission shaft and is connected with described taper sheath, 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.During connection, the shaft hole sleeve of motor output shaft is in the outside of described power transmission shaft left end portion, when tightening the first screw, taper sheath can be hauled the right-hand member to described power transmission shaft and moved, bellmouth can be expanded outwardly by taper sheath thus one end of allowing power transmission shaft be provided with bellmouth expands outwardly the most simultaneously, thus the left end portion of motor output shaft with described power transmission shaft is linked together, and ensure that and be reliably connected between motor output shaft and encoder axis hole, this processing greatly reducing parts and packaging technology difficulty, reduce cost.Because this structure is to make use of louvres numerous on motor fan housing, so the encoder for different installation dimensions has only to select the louvre of diverse location to carry out installing, this makes encoder installing and connecting apparatus can adapt to the installation connection of encoder of various different installation dimension.
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, and the second screw penetrates from the right-hand member of the axis hole of described encoder and the screw-internal thread fit of right end portion with described power transmission shaft.Can be pressed on first shaft shoulder to realize the connection of encoder axis hole and power transmission shaft by the axis hole of encoder by the second screw.The internal diameter of the right end portion of the axis hole of described power transmission shaft is more than the external diameter of a circle of the screw terminal of described first screw, the internal diameter of the mid portion of the axis hole of the described power transmission shaft external diameter more than the screw rod of described first screw and the external diameter of a circle of the screw terminal less than described first screw.Thus can realize being reliably connected of power transmission shaft and motor output shaft axis hole by screwing the first screw.The end face of described motor output shaft and the contact of second shaft shoulder, second shaft shoulder can carry out the location of axial direction to motor output shaft.It is additionally provided with the second through slot near the side of described bellmouth at described power transmission shaft, arrange one end that the second through slot can allow power transmission shaft be provided with bellmouth to expand outwardly smoothly, thus together with ensureing that motor output shaft is reliably connected with the left end portion of described power transmission shaft.Described encoder installing and connecting apparatus also includes mounting flange, described flexure strip is linked together by the body of described mounting flange with described encoder, described flexure strip includes the first installation portion, bending section and the second installation portion, first through hole corresponding with the screwed hole on described mounting flange it is provided with on described first installation portion, being provided with the second through hole corresponding with the louvre on motor fan housing during installation on described second installation portion, this structure is convenient to be connected with motor output shaft reliably by various sizes of encoder.
