Abstract
The utility model discloses a double shaft extension alternating current motor with a coder structure, comprising a double shaft extension alternating current motor and also comprising a protective cover, a coder and a connecting shaft, wherein, one end of the protective cover is provided with an opening and fixed on the motor by means of covering the shaft extension end; a connecting hole is arranged on the central part of the other end of the protective cover; one end of the connecting shaft is fixed on the free end of the shaft extension end; the other end of the connecting shaft passes through the connecting hole of the protective cover; the coder is provided with a center hole; one side of the coder is fixedly connected with the protective cover through bolts; the center hole is fixedly connected with the other end of the connecting shaft. The utility model has the advantages of capability of realizing commonality of wire outlet from the left side and the right side of the motor, and great reduction of expenditure.
Description
Technical field
The utility model provides a kind of alternating current machine, relates in particular to the alternating current machine that a kind of twin shaft is stretched the band coder structure.
Technical background
The shaft mode of alternating current machine generally is divided into twin shaft and stretches with single shaft and stretch two kinds.Twin shaft is stretched two of motor and is gone out axle head the main branch that axle head and pair go out axle head that goes out is arranged, and the major-minor shaft can both bringing onto load, and twin shaft is stretched motor generally can't install encoder.
At present, the alternating current machine that single shaft is stretched installs the commonplace of encoder additional at non-shaft stretching end, and this type of motor left side outlet and right outlet are uncurrent, if the motor of user's left side outlet and the motor of right outlet all need to buy spare part, then must buy respectively, increase expenditure.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and provides a kind of twin shaft to stretch the alternating current machine of band coder structure, and it can realize that the outlet of the motor left and right sides can both be general, has significantly reduced expenditure.
The technical scheme that realizes above-mentioned purpose is: a kind of twin shaft is stretched the alternating current machine of band coder structure, comprises a pair of shaft extension alternating current machine, wherein, also comprises a protective cover, an encoder and a coupling spindle, wherein:
Described protective cover one end has opening and is fixed on the motor in the mode that covers the shaft extension end, and other end middle part has a connecting hole;
Described coupling spindle one end is fixed in the free end of shaft extension end, and the other end passes the connecting hole of protective cover;
Described encoder has centre bore, and its side is fixedlyed connected with protective cover by screw, and its centre bore is fixedlyed connected with the other end of coupling spindle.
Above-mentioned a kind of twin shaft is stretched the alternating current machine of band coder structure, wherein, has coupling arrangement on the side of described encoder, and by being screwed on protective cover with the screw of this coupling arrangement relevant position on the protective cover.
Above-mentioned a kind of twin shaft is stretched the alternating current machine of band coder structure, and wherein, the inner chamber of described protective cover is a cylindrical inner chamber, and is outside cylindrical.
Above-mentioned a kind of twin shaft is stretched the alternating current machine of band coder structure, and wherein, described coupling spindle is one and has step-like cylinder.
Above-mentioned a kind of twin shaft is stretched the alternating current machine of band coder structure, and wherein, described twin shaft is stretched two ends footing measure-alike of alternating current machine.
Above-mentioned a kind of twin shaft is stretched the alternating current machine of band coder structure, and wherein, it is measure-alike that described twin shaft is stretched two shaft extension ends of alternating current machine.
The beneficial effects of the utility model are: a kind of twin shaft of the present utility model is stretched the alternating current machine of band coder structure, twin shaft by the two ends symmetry is stretched structure, when needs change the outlet box direction, only need that protective cover and encoder are pulled down transposing to an other end and get final product.After using alternating current machine of the present utility model, a motor both can be done left outlet, can do right outlet again, and the user only need prepare a motor and get final product when spare part.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
See also Fig. 1, there is shown a kind of twin shaft of the present utility model and stretch the alternating current machine of band coder structure, the size C1 of two ends footing 12 that this twin shaft is stretched alternating current machine is identical with C2, two shaft extension end size E1 are also identical with E2, it comprises a pair of shaft extension alternating current machine 1, a protective cover 2, an encoder 4 and a coupling spindle 5, wherein:
Above embodiment is only for the usefulness of explanation the utility model, but not to the restriction of the utility model protection range.Relevant those skilled in the art; under the situation that does not break away from spirit and scope of the present utility model; can also make various conversion or modification, and the technical scheme that all are equal to should belong to also within the category of the utility model protection, is limited by each claim.
