Abstract
A thermoforming trim press and a drive assembly for a thermoforming trim press are provided. The drive assembly includes a frame, a drive motor, a drive linkage, a first bevel gear, and a second bevel gear. The drive motor is supported by the frame. The first bevel gearbox is supported by the frame and has an input shaft coupled with a drive gear, an output shaft coupled with a ring gear, and a housing supporting the input shaft, the output shaft, the drive gear and the output shaft in meshed gear rotation. The second bevel gearbox is supported by the frame in opposed relation with the first bevel gearbox and has an input shaft coupled with a drive gear, an output shaft coupled with a ring gear, and a housing supporting the input shaft, the output shaft, the drive gear and the output shaft in meshed gear rotation, the second bevel gearbox driven via the drive linkage with the output shaft driving in counter-rotation relative to the output shaft of the first bevel gearbox. A method for driving a moving platen on a trim press is also provided using opposed, identical beveled gearboxes.
