Abstract
The invention concerns a spindle drive for a veneer lathe. In view of reducing the mobile masses of the drive gear equipment making the lathe better adaptable to different log lengths, the opposite spindles in the lathe are provided with drive motors of their own. In the preferred embodiment, the rotor of the motor is mounted directly on the spindle and the stator is mounted on a frame unit displaceable on guides. The motor may be an electric motor provided with speed regulation, or it may be a hydraulic motor.
Claims5
A veneer lathe comprising:
- first spindle means comprising a first spindle shaft and first grasping means for grasping one end of a log to be turned about a longitudinal axis of said lathe, said first spindle means being displaceable along said longitudinal axis to grasp said log;
- second spindle means disposed opposite to said first spindle means along said longitudinal axis, said second spindle means comprising a second spindle shaft and second grasping means for grasping another end of said log opposite said one end, said second spindle means being displaceable along said longitudinal axis to grasp said log;
- drive means for rotating at least one of said first or second spindle means about said longitudinal axis, said drive means comprising rotor means mounted on at least one of said first or second spindle shafts and stator means disposed in a frame around said rotor means.
