Machine tool spindles usually use three transmission methods: direct drive, gearbox drive and belt drive.
The direct drive method means that the torque output by the motor is directly transmitted to the spindle to realize the rotation of the spindle. This method has the advantages of compact structure and high transmission efficiency, but its scope of application is narrow and is generally only suitable for low-power, high-speed spindles.
The gearbox transmission method means that the motor transmits the braking force to the spindle through the gearbox to realize the rotation of the spindle. This method has a wide range of applications, but the transmission efficiency is low and transmission errors are prone to occur.
The belt drive method means that the motor transmits the braking force to the main shaft through the belt through parallel, cross or large pulleys to achieve the rotation of the main shaft. This method has a wide range of applications and high transmission efficiency, but problems such as belt loosening are prone to occur during the transmission process.
