The difference between universal coupling and flat plate

Universal couplingDifference from tablet
When grinding, you should push and pull with little effort. The common feature of universal couplings is that the angular compensation is large. The angle between the two axes of universal couplings of different structure types is different, generally ≤5°-45°.The universal coupling utilizes the characteristics of its mechanism to make the two shafts not on the same axis, and when there is an angle between the axes, it can realize the continuous rotation of the connected two shafts, and reliably transmit torque and motion.The biggest feature of the universal coupling is its large angular compensation capability, compact structure and high transmission efficiency.
To prevent squeezing out the oil and sand between the two plates.The trajectory of the upper plate shows an "8" movement, try to squeeze the oil between the platforms evenly, and the push and pull forces of both hands should feel the same.When more lubricating, the speed of rotating and pushing the upper plate should be increased at this time, a stroke is about 4~5 seconds, the stroke distance should exceed half of the platform size, and the swing amplitude should be increased.As time goes by, the attraction between the two stations gradually increases and is very even.When the cast iron platform moves, the sand itself moves and rolls. While cutting the platform, it is embedded by the platform, and at the same time it is squeezed out by other sands, squeezing each other.When the push-pull force reaches about 500N, the sand is embedded relatively firmly, and sand pressing can be completed.
      
       During the grinding process of the grinding platform, always pay attention to make all parts of the grinding plate wear evenly.Listen to the sound of grinding sand, whether there is a "sand" metal sound with the movement of the upper board, there should be no pauses or strange sounds; whether the oil stains between the surface of the sign are even.When the platform is pushed and pulled, it always runs in an "8" shape.When pulling the platform, be careful not to lift the plate upward with your hands.The force of both hands must be even, the speed must be stable, and the plate must be rotated 90° for several strokes.When rotating the plate and connecting the "8" movement, be sure to connect, smoothly transition, and try not to pause.The speed of pushing and pulling decreases as the attractive force between the plates increases.
