Abstract
A hydraulic drive assembly for a large pre-existing pressurized digester vessel and a method of installation of the hydraulic drive assembly have been conceived. Such a device includes a stub shaft which has a lower end and an upper end. The lower end engages with a hydraulic drive and the upper end is coupled to a drive shaft. The coupling further includes a top coupling and a bottom coupling. The top coupling is coupled to the drive shaft, and the bottom coupling is coupled to the stub shaft. A drive support bracket is attached to the hydraulic drive and then attached to the drive support bracket by at least one sole plate that is fixed to a foundation. The hydraulic drive assembly installation method is utilized when removing an electric motor and mechanical transmission device and replacing it with a hydraulic drive assembly.
