Abstract
A device on a slider crank for generating a motion relative to the a slider (press ram 5) of a part (ejecting spring pin 6) mounted on the slider, wherein such motion is taken off a crankpin (1) upon rotation of the crankpin around a crankshaft axis and transmitted along a pushrod (connecting rod 4) to the part (ejector spring pin 6). For this purpose, revolving parts (wheel 22, 34, 38; disk 98, 100, belt 102; disk 142, 148, belt 150) transmit rotary motion on the connecting rod (26, 28; 144) (FIG. 1).
Claims9
A slider crank with a device for the purpose of generating a motion relative to a slider of a part supported on the slider, with said motion being taken off a crankpin upon rotation around a crankshaft axis and transmitted along a connecting rod to the part from which an operating motion is taken off, characterized by the feature that in order to generate a rotary motion of that part on the slider around a single axis of rotation relative to both the slider and the connecting rod, there is provided a transmission comprising at least one rotating part provided directly on the connecting rod.
A slider crank with a device for the purpose of generating a motion relative to a slider of a part supported on the slider, with said motion being taken off a crankpin upon rotation around a crankshaft axis and transmitted along a connecting rod to the part from which an operating motion is taken off, characterized by the feature that in order to generate a rotary motion of that part on the slider around a single axis of rotation relative to both the slider and the connecting rod, a transmission comprising at least one rotating part that is provided on the connecting rod;
- the transmission has a driving toothed wheel that is mounted in fixed position on the crankpin, a driven toothed wheel that is moved forcibly and is mounted on a hinge joint pin that connects the connecting rod and the slider, and the at least one rotating part connects both toothed wheels;
- and the hinge joint pin carries a cam disk of a cam gear mounted on the slider and that the cam disk is connected in a fixed relationship with the driven toothed wheel.
A method for moving a ram, comprising the steps of:
- using a slider crank for moving the ram back and forth relative to and simultaneously with the moving slider, the slider crank being characterized by the feature that in order to generate a rotary motion of a part on the slider around a single axis of rotation relative to both the slider and a connecting rod connecting the slider to a crankpin that rotates around a crankshaft axis, a transmission comprising at least one rotating part that is provided on the connecting rod;
- the transmission having a driving toothed wheel that is mounted in fixed position on the crankpin, a driven toothed wheel that is moved forcibly and is mounted on a hinge joint pin that connects the connecting rod and the slider, and the at least one rotating part connects both toothed wheels;
- and the hinge joint pin carrying a cam disk of a cam gear mounted on the slider and that the cam disk is connected in a fixed relationship with the driven toothed wheel;
- and
- using the cam disk to control, by means of frictional contact, a forced rotation of a cam roller on a roller lever that is mounted in a pivot mount on the slider and acts upon the ram against the return force of a spring.
A method for rotating a toothed wheel comprising the steps of:
- using a slider crank for rotating the toothed wheel relative to the moving slider, the slider crank being characterized by the feature that in order to generate a rotary motion of a part on the slider around a single axis of rotation relative to both the slider and a connecting rod connecting the slider to a crankpin that rotates around a crankshaft axis, a transmission comprising at least one rotating part that is provided on the connecting rod;
- the transmission having a driving toothed wheel that is mounted in fixed position on the crankpin, a driven toothed wheel that is moved forcibly and is mounted on a hinge joint pin that connects the connecting rod and the slider, and the at least one rotating part connects both the driving and driven toothed wheels;
- and the toothed wheel that picks up the rotary motion of the driving toothed wheel meshes with the driven toothed wheel or with a coaxial toothed wheel that is connected with the driven toothed wheel in a fixed relationship;
- and
- where, for moving the ram simultaneously back and forth relative to the moving slider, the slider carries a cam disk of a cam gear mounted on the slider, and where this cam disk is connected in a fixed relationship with the toothed wheel and controls, by means of frictional contact, a forced rotation of a cam roller on a roller lever that is mounted in a pivot mount on the slider and acts upon the ram against the return force of a spring.
