Abstract: A machine for hard-rolling a workpiece such as a crankshaft includes a drive apparatus (7) for rotating the crankshaft (8, 113), suspension apparatuses (9 to 17), hard-rolling devices (18 to 26, 111) movably supported by the suspension apparatuses, and a crankshaft transport apparatus (100). Each hard rolling device is a scissors jaw including two scissors arms (46, 47, 114, 115), with respective hardening roller heads (66 to 69, 118) and respective opposite counter-support heads (74, 119) mounted on the upper ends of the scissors arms facing the crankshaft. Each suspension apparatus (9 to 17) is slidably adjustable along the rotation axis (27) of the drive apparatus (7). A drive arrangement (49, 122) is connected to the lower ends of the scissors arms directed away from the crankshaft, for closing and opening the scissors arms to a maximum opening width (59, 130) that is larger than twice the maximum structural radius (60, 131) of the crankshaft. A respective angled bellcrank lever (78) is pivotally supported on each suspension apparatus, with one shank thereof pivotally connected to one scissors arm and the other shank thereof connected to a piston cylinder unit (84), which in turn is connected to the suspension apparatus (9 to 17). Guide members (88, 89) are provided for guiding the upper ends of the scissors arms.

Abstract: A burner for burning liquid or gaseous fuels, especially heavy heating oil. A central fuel lance is surrounded by two annular channels that supply primary and secondary combustion air. The annular channels are surrounded by several outer fuel lances that are distributed along the arc of a circle and can optionally be displaced axially and by air nozzles that convey tertiary combustion air. The object is to burn fuel at a low output of pollutants in systems with a narrow combustion space. The burner has an annular flue-gas channel between the outer annular channel and the air nozzles. The burner opens into a chamber that is jacketed in ceramic and that a heat exchanger (flame tube) extends out of. Other nozzles that convey a component of the flow of tertiary air are mounted in the wall of the chamber.

Abstract: A crankshaft (6) is rotated about its axis (7), and all of its crankpins (28, 29, 30), which each respectively have an eccentricity (e) relative to the axis (7), are simultaneously rotary milled by respective allocated rotary milling cutters (34, 35, 36) of a milling cutter set (12). The individual milling cutters (34, 35, 36) each respectively have an eccentricity (e) corresponding to the eccentricity of the respective crankpin that is allocated to be machined by the respective milling cutter. Furthermore, the milling cutter set (12) is rotated at the same rotational speed, i.e. with a rotational speed ratio of 1:1, relative to the rotating crankshaft, while simultaneously the milling cutter set is moved in the X-direction toward the crank-shaft axis to achieve a feed advance. A rotary milling machine for carrying out the method includes a milling cutter set of which the milling cutters respectively have the same eccentricity as the respective allocated crankpins of the crankshaft to be milled, and includes a drive apparatus for achieving the 1:1 rotation of the milling cutter set relative to the crankshaft as well as the feed advance motion of the milling cutter set. In this manner, the milling cutters automatically follow the eccentricity of the crankpins, without requiring a complicated individual guidance.

Abstract: A crankshaft (6) is rotated about its axis (7), and all of its crankpins (28, 29, 30), which each respectively have an eccentricity (e) relative to the axis (7), and all of its main bearing pins (62, 63, 64, 65), which each have non-eccentric cylindrical surfaces, are simultaneously rotary milled by respective first and second allocated rotary milling cutters (34, 35, 36, 70, 71, 72, 73) of a milling cutter set (12). The individual first milling cutters (34, 35, 36) each respectively have an eccentricity (e) corresponding to the eccentricity of the respective crankpin that is to be machined by the respective first milling cutter, while the second milling cutters are non-eccentric circular cutters. The milling cutter set (12) is rotated at the same rotational speed, i.e. with a rotational speed ratio of 1:1, relative to the rotating crankshaft, while simultaneously the milling cutter set is moved in the X-direction toward the crankshaft axis to achieve a feed advance. A rotary milling machine for carrying out the method includes a milling cutter set having the above described first eccentric and second non-eccentric milling cutters, and a drive apparatus for achieving the 1:1 rotation as well as the feed advance motion of the milling cutter set relative to the crankshaft. In this manner, the milling cutters automatically follow the eccentricity of the crankpins, and the non-eccentric rotation of the main bearing pins, without requiring a complicated individual guidance.
