Abstract
The utility model relates to a bearing air seal protection type photoelectric encoder for a shaft, comprising a casing, a photoelectric encoder and a reading head. The bearingless air seal protective type photoelectric encoder for the shaft is characterized by further comprising an inner ring matching with the shaft; the casing is fixedly sleeved on the inner ring, and the casing and the inner ring are in sealing connection; and the inner ring is fixedly provided with the photoelectric encoder, and the photoelectric encoder and the reading head are positioned in the casing. With adoption of the scheme, the utility model has the advantages that the photoelectric encoder is combined with a curved circuit and air seal protection under the condition of no bearing so that the bearing is omitted; and the bearing air seal protection type photoelectric encoder for the shaft can be fit for high speed operation, has high precision and good reliability, is convenient in mounting, is impact-resistant, dustproof and pollution-free, and is an ideal matching part of modern high-speed high-precision spindles.
Description
Technical field
The utility model relates to a kind of photoelectric encoder, relates in particular to a kind of with no bearing sealing gland protection type photoelectric encoder.
Background technology
Main shaft is the high precision machine tool functional part, rotating speed and control accuracy are more and more higher, photoelectric encoder is that main main shaft angle position signal feedback assembly is used more and more widely, is what separate and present no bearing photoelectric encoder is a code-disc with read head, and protective is poor, easily breaks, pollute, assembling will be adjusted read head separately, the read head easy break-down, and reliability is low.
Summary of the invention
The utility model is at the existing in prior technology shortcoming, and provides a kind of easy for installation, and barrier propterty is good, and unfailing performance is good, and anti-collision is dustproof, the no bearing sealing gland protection type photoelectric encoder of antipollution axle.
The utility model is realized by following technical measures: a kind of with no bearing sealing gland protection type photoelectric encoder, it comprises shell, photoelectric code disk, read head, it is characterized in that, it also comprises the inner ring that cooperates with axle, described shell be fixedly set on the inner ring and shell and inner ring between be tightly connected, be installed with photoelectric code disk on the described inner ring, described photoelectric code disk, read head are positioned at shell.
Concrete characteristics of the present utility model also have, and shell is fixedlyed connected with the housing of axle, and described shell is provided with the sealing gland interface.Can introduce the pressurized air of cleaning by the sealing gland interface, guarantee the inner malleation that keeps of scrambler, block extraneous dirt and enter scrambler, prevent the contaminated inefficacy of code-disc and read head.
Concrete characteristics of the present utility model also have, and photoelectric code disk is fixed on the described inner ring by rivet.
The beneficial effect of this programme can learn that the present invention under the situation of no bearing, is combined in one to photoelectric code disk according to the narration to such scheme, add the protection of Qu Lu and sealing gland, saved bearing, can adapt to and run up the precision height, unfailing performance is good, easy for installation, anti-collision is dustproof, anti-pollution, be the desirable matching component of Modern High-Speed high precision main shaft.

Among the figure, 1, axle, 2, bearing, 3, housing, 4, screw, 5, read head, 6, shell, 7, rivet, 8, inner ring, 9, photoelectric code disk, 10, screw, 11, the sealing gland interface, 12, the scrambler mounting screw.
Embodiment
For clearly demonstrating the technical characterstic of this programme,, this programme is set forth below by an embodiment.
As shown in Figure 1, the utility model be a kind of with no bearing sealing gland protection type photoelectric encoder, it comprises shell 6, photoelectric code disk 9, read head 5, it also comprises and axle 1 inner ring that cooperates 8, described shell 6 be fixedly set on the inner ring 8 and shell 6 and inner ring 8 between be tightly connected, photoelectric code disk 9 is fixedly mounted on the inner ring 8 by rivet 7, and photoelectric code disk 9, read head 5 are positioned at shell 6.Shell 6 is fixedlyed connected with the housing 3 of axle 1, and described shell 6 is provided with sealing gland interface 11.
When the utility model was installed and used, the shell 6 of photoelectric encoder was connected with the housing 3 of axle 1, inner ring 8 is sleeved on the axle 1, and rigging position is adjusted by adjusting pad, guarantees that the labyrinth clearance and the reading of photoelectric encoder is normal.
The utility model can pass through existing techniques in realizing without the technical characterictic of describing, and does not repeat them here.Certainly; above-mentioned explanation is not to be to restriction of the present utility model; the utility model also is not limited in above-mentioned giving an example, and variation, remodeling, interpolation or replacement that those skilled in the art are made in essential scope of the present utility model also should belong to protection domain of the present utility model.
Claims (3)
