Abstract
A movable machine, for example a saw, has a light construction using composite materials such as fiber reinforced resins and a closed cell foam. The saw may have a housing formed from multiple skins of the composite materials in which is located the closed cell foam. Metallic inserts may be used to bond to either or both of the foam and the composite skin to accept working components. A saw is also described which uses gears sharing the same support element.
Claims48
A movable machine having a motor and a shaft linked to the motor for driving a machining tool, a housing adjacent the motor wherein the housing is formed from a composite of oriented reinforcing fibers and plastic and wherein the housing includes a foam core adjacent the composite.
A movable machine having a motor and a shaft linked to the motor for driving a machining tool, a housing adjacent the motor wherein the housing is formed from a composite of oriented reinforcing fibers and plastic and further comprising an insert bonded to the housing.
A movable machine having a motor, a housing supporting the motor and having a housing wall formed from a composite of oriented fibers and a closed cell foam adjacent the housing wall.
A movable machine having a motor and a shaft linked to the motor for driving a machining tool and having a housing extending adjacent at least part of the motor, wherein the housing includes a housing wall formed from a composite of oriented fiber reinforced plastic extending over a body layer and further including the machining tool in the form of a saw blade.
A movable machine having a motor and a shaft linked to the motor for driving a machining tool and having a housing extending adjacent at least part of the motor, wherein the housing includes a housing wall formed from a composite of oriented fiber reinforced plastic extending over a body layer and wherein the body layer includes a foam and further including an adhesive layer bonding the fiber reinforced plastic and the foam.
A movable machine having a motor and a shaft linked to the motor for driving a machining tool and having a housing extending adjacent at least part of the motor, wherein the housing includes a housing wall formed from a composite of oriented fiber reinforced plastic extending over a body layer and wherein the body layer is a foam.
A movable machine having a motor and a shaft linked to the motor for driving a machining tool and having a housing extending adjacent at least part of the motor, wherein the housing includes a housing wall formed from a composite of oriented fiber reinforced plastic extending over a body layer and further including a carriage for the motor and housing configured to operate on a track.
A movable machine having a motor and a drive mechanism for transmitting motion from the motor to a machining tool and a housing having a housing portion adjacent the motor, the housing being formed from a composite of oriented reinforcing fiber and plastic, and wherein the housing portion is curved and further including a foam material bonded to the first and second housing portions.
A movable machine having a motor and a drive mechanism for transmitting motion from the motor to a machining tool and a housing having a housing portion adjacent the motor, the housing being formed from a composite of oriented reinforcing fiber and plastic, and wherein the housing portion is curved and further including an insert contacting the reinforcing fiber and plastic and a roller assembly extending into the insert.
A movable machine having a motor and a drive mechanism for transmitting motion from the motor to a machine tool, a housing extending adjacent at least part of the motor and having a housing wall formed from a composite of fiber reinforced plastic extending over a body layer and further including at least one insert bonded to at least one of the fiber reinforced plastic and the body layer.
A movable machine having a motor and a drive mechanism for transmitting motion from the motor to a machine tool and a housing for part of the machine formed from a fiber reinforced plastic and a UV radiation absorbing material on the housing.
A wall saw having a motor mounted on a carriage and a drive mechanism linked to the motor wherein the carriage is formed from a fiber reinforced material bonded to a foam and wherein the drive mechanism is housed in a housing having a housing portion formed from a fiber reinforced material.
