Publication number: 20200132120Abstract: A cage arrangement comprises substantially flat rollers, which are guided in a roller cage arranged on a housing and are held in position by a substantially strip-like cage metal sheet attached to the housing at a position remote from the roller region. The cage metal sheet has a retaining piece that protrudes in the direction of a roller in an intended installation position and has an end-face region, the shape of which corresponds to that of a roller surface facing the retaining piece.Type: ApplicationFiled: March 22, 2018Publication date: April 30, 2020Applicant: Hegenscheidt-MFD GmbHInventors: Toni STEFFENS, Johannes ZIMMERMANN, Werner KISSER

Patent number: 10421115Abstract: The invention discloses a hard-rolling roller head with two separate housings for deep rolling the outside radii of adjoining crankpins of a split-pin crankshaft. The hard-rolling roller head provides an effective support of the two housings against one another, when machining split-pin crankshafts, and simultaneously prevents the upper areas of these housings from drifting apart.Type: GrantFiled: March 1, 2017Date of Patent: September 24, 2019Assignee: HEGENSCHEIDT-MFD GmbHInventors: Hans Toni Steffens, Hans Zimmermann

Patent number: 9987722Abstract: The invention relates to a hard-rolling roller for a deep rolling tool having a torus-shaped base body for deep rolling of radiuses or recesses which limit the bearing trunnion on crankshafts on both sides, and two at least approximately truncated cone-shaped central bodies, rising on both sides of the body. A cylindrical body rises on the upper end surface of one of the two central bodies.Type: GrantFiled: July 20, 2012Date of Patent: June 5, 2018Assignee: Hegenscheidt-MFD GmbH & Co. KGInventors: Hans-Toni Steffens, Hans Zimmermann

Patent number: 7487657Abstract: The invention concerns a deep rolling head (2) of a deep rolling tool of a shears-type deep rolling unit of a deep rolling machine used for the deep rolling of radii or fillets (5, 6) on the bearing pins (9) of crankshafts (7) with the aid of deep rollers (4) that are rotatably supported in the deep rolling head (2) with appropriate clearance, whereby the deep rolling head (2) is mounted at the outer end of one of the two shears arms (1) of the deep rolling unit. The deep rolling head (2) is pivotably attached to the end (1) of the shears arm.Type: GrantFiled: January 19, 2007Date of Patent: February 10, 2009Assignee: Hegenscheidt-MFD GmbH & Co.

Patent number: 7257974Abstract: The invention relates to a deep-rolling roller head (1) of a deep-rolling tool for deep-rolling, by means of deep-rolling-rollers (2), radii or recesses (3) on the main (4) and lifting bearing journal of a crankshaft, while the crankshaft rotates in a rotational direction (5). The deep-rolling roller head (1) has a prismatic, flat, approximately rectangular housing (6) on whose one front side (7), which faces the bearing journals (4) to be deep-rolled of the crankshaft, two roller cages (8, 9) are provided. The roller cages (8, 9) each have first front sides (10, 11), which are at a mutual distance (12) from each other and at the same time at a distance (13, 14) from the longitudinal center (15) of the housing (6). The roller cages (8, 9) have recesses (16), in which deep-rolling rollers of (2) are loosely rotatably guided in a removable manner with play.Type: GrantFiled: November 4, 2005Date of Patent: August 21, 2007Assignee: Hegenscheidt-MFD GmbH & Co.

Patent number: 6691543Abstract: The fixed roll apparatus (8) of a fixed roll machine (1) for crankshafts (3) is constructed scissors-fashion. Two pivotable scissor arms (9 and 10) disposed opposite one another each bear a fixed roll head (13) and a support roll head (14) respectively. The support roll head (14) has two axis-parallel support rolls whose axes of rotation lie in a common plane. The support roll head (14) also has an axial guide roll which is disposed in front of the support rolls in the pivoting direction (35) for closure and whose axis of rotation is perpendicular to the axis of rotation of the crankshaft (3) and lies in a plane which forms an acute angle with the common plane of the axis of rotation of the support rolls, its diameter being larger than the width of the support roll head (14) and slightly smaller than the spacing of the adjacent oil collars of a main bearing pin or a connecting rod bearing pin.Type: GrantFiled: March 14, 2002Date of Patent: February 17, 2004Assignee: Hegenscheidt-MFD GmbH & Co. KGInventors: Hans-Toni Steffens, Hans Zimmermann
