108 mm, glueballs extended position are located at 103 mm of φ, such as install big belt pulley, and since outer diameter is 106 mm of φ, glueballs is shunk, will
Big belt pulley is fixed, and small belt pulley is such as installed, and since outer diameter is 101 mm of φ, is not fixed by glueballs, to prevent belt pulley mixed
Dress;
Or clamp ring internal diameter is φ 103mm, glueballs extended position is located at 98 mm of φ, small belt pulley is such as installed, due to outer diameter
For 101 mm of φ, glueballs shrinks, small belt pulley is fixed, and such as installs big belt pulley, since outer diameter is φ 106mm, not by glueballs
It is fixed, to prevent belt pulley from loading in mixture.
Compared with prior art, the beneficial effects of the utility model are as follows:
1, the utility model is simple in structure, easy to operate, by using belt pulley mixed loading detection device, including link block,
Pressure head, spring, mandrel, clamp ring and glueballs;Link block is interference fitted with pressure head, ensures link block upper surface and mandrel belt pulley
Contact surface depth of parallelism 0.02mm, link block and pressure head coaxiality of inner hole 0.02mm are arranged movable glueballs on pressure head, install belt
It can float after wheel, to carry out press fitting buffering, mandrel and pressure head endoporus clearance fit, concentricity 0.02mm, mandrel when work
It slides in pressure head endoporus, is released mandrel by spring when not working, mandrel and belt pulley clearance fit;The above structure composition one
Whole, close fit combines detection structure and press fitting, can complete the operation of linking.
2, movable glueballs and clamp ring therein, provide the important feature of installation, are set for different size of belt pulley
Different internal diameters is set, can be accurately detected, mechanization, intelligence degree are high, do not need manual intervention, can solve existing
Have the technical issues of belt pulley that similar size cannot be differentiated present in technology, can it is simple, efficiently, accurately detect difference
The belt pulley of size prevents from loading in mixture, and improves installation effectiveness, ensures the service life of belt pulley.
