Connected mode between motor of the prior art and the vibrator of vibrosieve generally has: belt pulley connects and Hooks coupling universal coupling connects two ways.
Belt pulley connection has the disadvantage that
1) belt transmission needs pretightning force so that vibrosieve has side force to exist, and vibrosieve even running is had certain impact.
2) negative pulley wheel is connected on vibrator, and pulley centerline can change with shaker vibration so that drivewheel and follower centre-to-centre spacing produce mechanical periodicity, motor is produced very strong periodic vibration power.For this, we need to eliminate the effects of the act at more complicated motor base.
Hooks coupling universal coupling connection mainly has the disadvantage that
Be not suitable for large-amplitude vibration sieve.When vibrosieve amplitude is bigger, universal coupling has very big power and transmits between motor and vibrosieve.For eliminating this power, it is very long that Hooks coupling universal coupling needs design, and erecting bed limited space, have impact on the application of this technology.
