Two-speed transmission having enclosed flywheel

A transmission system for a press machine comprising:

• an oil housing to provide lubrication therein,
• a shaft rotatably mounted within said oil housing,
• a flywheel rotatably mounted within said oil housing,
• means for applying rotation to said flywheel from outside said oil housing,
• high speed and low speed clutches mounted adjacent said shaft within said housing,
• means for selectively operating said clutches to transmit rotative motion from said flywheel to said shaft through either of said clutches, and
• brake means disposed between said clutches and operable to brake said shaft when neither clutch is engaged.

A transmission system for a press machine comprising:

• an oil housing to provide lubrication therein,
• a shaft rotatably mounted within said oil housing,
• a flywheel rotatably mounted within said oil housing,
• means for applying rotation to said flywheel from outside said oil housing,
• high speed and low speed clutches mounted adjacent said shaft within said housing,
• means for selectively operating said clutches to transmit rotative motion from said flywheel to said shaft through either of said clutches, and
• apertures formed through said shaft for admission of lubricating oil and fluid for energizing said clutches.

A clutch system comprising:

• a rotatable shaft,
• a flywheel rotatably mounted on an end portion of said shaft,
• means for rotating said flywheel,
• a high speed clutch assembly including friction clutch surfaces mounted about said shaft and engaged with said flywheel,
• a low speed clutch assembly spaced from said high speed clutch assembly and including friction clutch surfaces mounted about said shaft,
• a freely rotatable idler gear having a first gear which meshes with a gear on said flywheel and a second gear which meshes with a gear engaging said low speed clutch assembly in order to transmit rotative motion from said flywheel to said low speed clutch assembly,
• a brake assembly disposed between said low and high speed clutch assemblies and including a plurality of friction surfaces mounted about said shaft, and
• means for selectively engaging either of said clutch assemblies to transmit rotation from said flywheel to said shaft while concurrently disengaging said brake assembly.

A transmission system for a press machine comprising:

• a lubrication housing,
• a rotatable shaft wholly mounted in said housing,
• a flywheel supported by and rotatably mounted on said shaft,
• means for rotating said flywheel from outside said housing,
• a first speed clutch mounted on said shaft adjacent said flywheel and including a plurality of first friction clutch surfaces,
• first gear means attached to said flywheel and engaging the outer peripheries of ones of said first friction clutch surfaces,
• a second speed clutch mounted on said shaft and spaced from said flywheel and including a plurality of second friction clutch surfaces,
• second gear means rotatably mounted on said shaft and engaging the outer peripheries of ones of said second friction clutch surfaces,
• third gear means meshing with said first and second gear means for transmitting rotation from said flywheel to said second speed clutch, and
• means for selectively energizing either of said clutches to transmit rotation from said flywheel to said shaft.

A transmission system for a press system comprising:

• an enclosed oil housing,
• a shaft rotatably mounted in said housing,
• a flywheel rotatably mounted on said shaft within said housing,
• a motor mounted outside said housing,
• a gear extending through said housing and engaging said flywheel,
• means for transmitting rotation from said motor to said gear to rotate said flywheel,
• clutch means on said shaft for being engaged to transfer rotation from said flywheel to said shaft, and
• a brake within said oil housing for being automatically engaged when said clutch means are de-energized.
