Abstract
A wet-type flywheel brake system for use in a mechanical press includes a first and second brake assembly each installed within a respective brake housing space defined in a non-rotational quill. Each of the brake assemblies includes a brake lining element arranged in lateral facing relationship with the flywheel and an associated hydraulic seal-type piston that selectively moves the brake lining element into a friction-type braking engagement with the flywheel. The brake housing spaces are flooded with oil to immerse the brake lining elements. Oil for this purpose is provided from a flywheel bearing assembly integrated with the quill assembly and which is arranged for fluid communication with the quill-located brake housing spaces.
Claims23
An assembly for use with a flywheel assembly of a press machine, said flywheel assembly including a flywheel rotatable relative to a frame structure of said press machine, said assembly comprising:
- housing means for defining at least one brake housing space adjacent said flywheel at a respective side thereof;
- and
- at least one brake assembly, each brake assembly being disposed, at least in part, within a respective one of said at least one brake housing space defined by said housing means and being operative to selectively apply a braking action to said flywheel at the respective side thereof, said each brake assembly having a respective flywheel engaging member arranged in facing relationship with said flywheel at the respective side thereof, and an associated hydraulic piston means for selectively reversibly moving said flywheel engaging member into braking engagement with said flywheel in response to the hydraulic activation thereof.
An assembly for use with a flywheel of a press machine, comprising:
- a housing means for defining at least one brake housing space adjacent said flywheel at a respective side thereof;
- at least one brake assembly, each brake assembly being disposed, at least in part, within a respective one of said at least one brake housing space defined by said housing means and being operative to selectively apply a braking action to said flywheel at the respective side thereof;
- a quill assembly including a quill non-rotationally connected to said press machine, said flywheel being axially mounted to said quill;
- said quill including a first recess formed therein and disposed adjacent said flywheel at one said thereof, said first quill recess having disposed therein a respective brake assembly;
- and
- said quill further including a second recess formed therein and disposed adjacent said flywheel at another side thereof, said second quill recess having disposed therein a respective brake assembly.
A system for use with a flywheel assembly of a press machine, said press machine including a quill assembly having a quill non-rotationally connected to said press machine, said flywheel assembly including a flywheel rotatable relative to a frame structure of said press machine and axially mounted to said quill, said system comprising:
- a first brake assembly disposed at least in part within a first brake housing space defined in said quill, said first brake housing space being disposed adjacent said flywheel at a first side thereof, for selectively applying a braking action to said flywheel;
- said first brake assembly comprising:
- a respective flywheel engaging member arranged in facing relationship with said flywheel at the first side thereof, and
- an associated hydraulic piston means for selectively reversibly moving said flywheel engaging member into braking engagement with said flywheel in response to the hydraulic activation thereof;
- and
- a second brake assembly disposed at least in part within a second brake housing space defined in said quill, said second brake housing space being disposed adjacent said flywheel at a second side thereof, for selectively applying a braking action to said flywheel;
- said second brake assembly comprising:
- a respective flywheel engaging member arranged in facing relationship with said flywheel at the second side thereof, and
- an associated hydraulic piston means for selectively reversibly moving said flywheel engaging member into braking engagement with said flywheel in response to the hydraulic activation thereof.
