AI Technical Summary
In the steel rolling process, under the four-sliced rolling process, the starting roller is inclined due to its own weight, which affects tension adjustment and stability, resulting in differences in tension of rolled parts, wave blowing, running steel, stacking steel and scratching of finished products.
The photoelectric encoder coupling is adopted, including an annular elastic element, axle sleeve and a positioning pin. The vibration, axial displacement and radial jump of the measured shaft are absorbed through the annular elastic element to reduce the wear of the photoelectric encoder.
It effectively reduces wear of the photoelectric encoder, extends the service life of the encoder, and reduces installation requirements, allowing a little deviation between the axis to be tested and the axis of the encoder.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of measurement and testing, in particular to a photoelectric encoder coupling. Background Art
[0002] In the steel section rolling process, the rolling procedure required for the split rolling is more complicated. The original three-split rolling process is changed to the four-split rolling process, and the required tension stability is more important. The original design of the looper roll is connected by a single-sided swing arm. The roller length required for three splits has reached the limit. In the four-split rolling process, the single-sided swing arm connected to the roll is affected by its own weight. In addition, after the roll rises, the rolled piece acts downward, and the cylinder piston rod will stick to the sealing side, and the body will tilt significantly. On the one hand, it has a serious impact on the adjustment of tension and stability. The tension of each rolled piece is significantly different, which is difficult to adjust and control. The rolled piece often produces "waves", and steel runs and piles up. At the same time, the finished product will be scratched, and the qualified rate of the finished product is seriously restricted; on the other hand, it will also cause abnormal wear of copper sleeves, connecting rods and other components. Utility Model Content
[0003] The utility model aims to provide a photoelectric encoder coupling, which absorbs vibration, effectively reduces the wear of the photoelectric encoder and prolongs the service life of the encoder.
[0004] A photoelectric encoder coupling comprises: an annular elastic element and two shaft sleeves installed on the annular elastic element, wherein the annular elastic element is located between the two shaft sleeves, a positioning hole is provided on the side wall of the shaft sleeve, and a positioning pin is provided in the positioning hole.
[0005] In one embodiment, the photoelectric encoder coupling also includes a gasket, which is provided with a through hole, a bolt, and a nut. The gasket is located between the sleeve and the annular elastic element. The bolt passes through the side wall of the annular elastic element, passes through the through hole, and is tightened with the nut.
[0006] In one of the embodiments, the gasket is provided with at least three through holes, and the three through holes are distributed around the sleeve.
[0007] In one of the embodiments, the annular elastic element is formed by bending an elastic sheet ring, and the two ends of the bent elastic sheet are covered by a gasket. The gasket is provided with through holes at both ends of the elastic sheet, and the bolts are respectively passed through the two ends of the elastic sheet and tightened with the nuts.
[0008] In one of the embodiments, the positioning hole is provided with an internal thread, the positioning pin is a locking top screw, and the positioning pin is screwed into the positioning hole.
[0009] Compared with the prior art, the advantages of the photoelectric encoder coupling of the utility model are:
[0010] 1. The measured shaft and the encoder shaft are not coaxial and have a slight deviation. The vibration, axial displacement and radial runout of the measured shaft will be absorbed by the annular elastic element 3, which will not affect the normal operation of the encoder, effectively reducing the wear of the photoelectric encoder and extending the service life of the encoder.
[0011] 2. The installation requirements of the encoder can be reduced. The rotating axis of the photoelectric encoder and the measured axis are not required to be on the same axis, and the normal operation of the encoder can be guaranteed even if the angle deviation exceeds the allowable range of the encoder.

[0020] like Figure 1 , 2 As shown, the present embodiment is a photoelectric encoder coupling, comprising: an annular elastic element 3, two sleeves 1 mounted on the annular elastic element 3, the annular elastic element 3 is located between the two sleeves 1, the side wall of the sleeve 1 is provided with a positioning hole, and the positioning hole is provided with a positioning pin 2. The two sleeves 1 are used to insert the measured shaft or the shaft of the encoder, even if the measured shaft and the shaft of the encoder are not coaxial and have a slight deviation, the vibration, axial displacement, and radial runout of the measured shaft will be absorbed by the annular elastic element 3, which will not affect the normal operation of the encoder, effectively reducing the wear of the photoelectric encoder and extending the service life of the encoder.
[0021] The positioning hole is provided with an internal thread, and the positioning pin 2 is a locking screw, which is screwed into the positioning hole. When the measured shaft is inserted into the sleeve 1, the positioning pin 2 is tightened, and the locking screw is tightened to hold the measured shaft through the internal thread, thereby realizing the connection between the measured shaft and the coupling.

The bolt 4 passes through the side wall of the annular elastic element 3, passes through the through hole, and is screwed with the nut 5. The shaft sleeve 1 is connected to the annular elastic element 3 through the gasket 6, so that the connection between the shaft sleeve 1 and the annular elastic element 3 forms a wider plane, which is stable in force and reduces the vibration of the shaft during rotation.
[0023] Preferably, the gasket 6 is provided with at least three through holes, and the three through holes are distributed around the sleeve 1. The sleeve 1 is installed in a multi-point fixing manner so that the sleeve 1 and the annular elastic member are evenly stressed and vibration is reduced.

If different diameters of the tested shafts are tested, the bolts 4 and nuts 5 can be loosened to replace the sleeves 1 of different diameters, which has a wide range of applications; similarly, the sleeve 1 can also be replaced to apply encoders of different shaft diameters.
