Research on synchronous belt wheels by domestic and foreign peers

Since the development of synchronous belt pulley with synchronous belt, the use of synchronous belt is ubiquitous. In China, the development has become increasingly mature, and the requirements for the use of synchronous belt transmission are becoming higher and higher. Engineering and technical personnel have also discovered many problems and defects in synchronous belt transmission, which need to be solved theoretically and analyzed and improved through experiments. Believe in synchronous pulleys and belts in the same industry domesticallyManufacturers are researching and designing the tooth profile of synchronous belt pulleys, the material issues of synchronous belts, and the design methods of synchronous belt transmissions. These requirements have promoted the development of research on synchronous belt transmission theory. According to data reports, the theoretical research on synchronous belt transmission in foreign countries can be roughly divided into six aspects:

1. Synchronous belt drive design calculation: Synchronous belt drive design calculation is the main basis for selecting the structural parameters of synchronous belts and synchronous belt pulleys, and has received attention from synchronous belt manufacturers and users in various countries. Many enterprise standards have proposed their own design and calculation methods for selecting synchronous belt parameters.

2. Research on the Strength of Synchronous Belt Transmission: In terms of strength research, the most prominent is the experimental study by Toshio Koyama et al. from Japan. They analyzed the strength of synchronous belts from various aspects such as load distribution between belt teeth, pitch difference between synchronous belts and synchronous belt wheels, fatigue strength and fracture characteristics of synchronous belts, and the influence of incomplete meshing of synchronous belts. In addition, Soviet scholars such as Gorevich also conducted in-depth research on the service life and reliability of synchronous belts, and may regard the strengthening ribs of synchronous belts as important points.

How does the synchronous belt pulley rotary encoder detect the displacement of a straight line

1. Use an "elastic coupling" to directly couple the rotary encoder with the main shaft of the power device that drives linear displacement;

2. Use a small gear (spur gear, Dongguan light wheel, bevel gear or worm gear) box to couple with the power unit;

3. Use gears that rotate on a straight rack to transmit linear displacement information;

4. Obtain linear displacement information on the sprocket of the transmission chain;

5. Obtain linear displacement information on the synchronous belt of the synchronous pulley;

6. Use a rotary encoder with magnetic rollers installed to obtain displacement information on a flat steel material surface with linear displacement (to avoid slip);

7. Use a "retractable steel wire assembly" similar to a "steel tape measure" to connect a rotary encoder to detect linear displacement information (data processing must overcome stacking and winding errors);

8. Similar to 7, a "retractable steel wire assembly" with a small torque motor is used to connect a rotary encoder to detect linear displacement information (currently there are similar products in Germany with complex structures, lightweight wheel processing factories, and almost no stacking winding errors).

Synchronous belt pulley: In the following situations, the vehicle must be stopped:

When leaving the workplace;

When installing and adjusting workpieces, cutting tools, measuring dimensions, aligning templates, and checking smoothness;

3. When cleaning the iron filings on the planer or when the equipment is not functioning properly;

When checking the lubrication condition of the guide rail;

5. When lifting the crossbeam, the clamping device must be loosened first, and then clamped. After the horizontal joint beam is lowered, the crossbeam must be lifted a little more to eliminate the gap between the crossbeam lifting screw and nut;

Before and during the operation of the machine tool, attention should be paid to the height between the workpiece, fixture, tool, and tool holder to avoid collisions and accidents. The smaller the length of the extended slide of the cutting tool and tool holder, the better;

When assembling and disassembling workpieces, it is necessary to cooperate well with the crane operator and pay attention to equipment safety and personal safety;

8. Pay attention to whether the protective plate of the workbench is properly fixed to prevent metal powder and shavings from falling onto the sliding surface and damaging the guide rail;

9. When the workbench is running, it is not allowed to remove shavings and other items on the table to prevent them from falling into the bed and damaging the machine tool rails and gears;

When the machine tool malfunctions or is abnormal, it should be stopped immediately for troubleshooting or maintenance personnel should be notified for inspection.
