Abstract： |
The drive mechanism comprises the drive mechanism bracket, the driving chain, the system for measuring the position of the rod and the magnetic damper. The driving chain consists of the motor, the gear reduction mechanism and the chain wheel. The magnetic champer comprises the moving disc, the upper and lower magnetic discs and the bearing seat. Since playing the damping function only without the driving function as well as the adjustable structure, the magnetic damper provides the features of shorter driving chain, smooth reliable driving and large enough brake moment. Said mechanism reduces the influence of the precision of manufacturing and assembling the control rod driving mechanism on the rod drop as well as eliminates the 'scraping' between the moving disc and the magnetic disc. |
