Definitions

  • This invention relates to deep rolling of fillets of engine crankshafts or other annular areas of metallic workpieces which are subjected to high stress loads and in particular to a new and improved machine, a rolling tool and a method for simultaneously deep rolling the fillets of angularly offset, adjacent crank pin seats to increase their fatigue strength and surface hardness.
  • crankshaft Due to the design of the crankshaft and this offset of the crankpin seats, the crankshaft can be loaded to such an extent on the fillet areas of the crankpin seats that the fillets tear and bending of the crankshaft can occur during engine operation, so that the service life of the crankshaft is considerably reduced becomes.
  • the crankshaft can be strengthened by increasing the crank pin seat diameter and by heat treatment (quenching and tempering) of the crankshaft in order to increase its form and fatigue strength become.
  • the fatigue strength and durability of crank pins and main bearing seats can be significantly increased by rolling compressive stresses into the metal of the annular fillets between the pin seats and the adjacent counterweights or bearing shells.
  • the present invention relates to a new and improved fillet rolling method, rolling tool and apparatus suitable for the new and improved simultaneous deep rolling and permanently hardening the fillets of angularly offset crank pin seats and other annular spaces.
  • the upper tool of this invention includes side-by-side main housings in which back-up rolls are mounted.
  • a cage which carries an angled or inclined processing roller which is in rolling contact with a peripheral surface of the support roller so that the load applied to the housing via the support roller onto the inclined metal processing roller and from there onto the granular structure of the metallic crankpin grooves which are to be rolled for the purpose of permanent strengthening is transferred.
  • crankshaft the pin grooves of which are to be rolled
  • a motor which is connected to the chuck for driving so that the processing rollers roll the annular grooves of the crank pin under pressure .
  • An annular cage thrust bearing assembly operably disposed between the tool housings maintains their alignment in parallel planes as they are rotated relative to one another and about the axis of an engine crankshaft. It is very important that this thrust bearing assembly be a device that absorbs and cancels the opposing resulting side thrust forces generated by the opposed and outwardly inclined rolls during the rolling process. When the opposing side pressure loads are released, the tool remains in the center even when the seat portions of each pin are angularly offset.
  • a pair of lower support tools are provided, each having two backup rolls that hold the pin seats when the work rolls of the upper tool roll down the fillets of the piston pins.
  • These support rollers are arranged between the pin seats in order to absorb the rolling loads transmitted by the pin seats, so that no significant bending loads are applied to the crankshaft to be rolled.
  • the upper and lower pairs of tools are each held in parts by upper and lower claws with an oscillating clamp structure, each comprising a pair of levers which are rotatably connected to each other by an intermediate pivot.
  • Hydraulic Drive cylinders which connect the end portions of the clamping levers to one another, can be actuated in such a way that, through the driven expansion of the cylinders, they generate the machining force which is transmitted to the fillet rollers via the claws.
  • the clamping structure for an oscillating operation is "rotatably held by holding rocker arms which swing back and forth or swing in the manner of a pendulum during the deep rolling process.
  • a new and improved method of fillet rolling a metallic component such as e.g. of a journal seat of a crankshaft, in which angularly offset, annular fillets from adjacent journal seat sections are rolled simultaneously to expose the metal of the fillets to a compressive stress and thereby to increase the fatigue strength of the component.
  • Another feature, another object and another advantage of the invention is to provide a new and improved metal rolling machine comprising pairs of rotatably connected levers with metal working rollers in a tool arranged in clamping claws of the levers which are about an axis of an engine crankshaft oscillate to simultaneously roll pairs of staggered, annular fillets of staggered journals of the crankshaft.
  • Another feature, object, and advantage of the invention is that it provides a new and improved tool for rolling annular and angular machining areas such as e.g. Provides fillets of crankshaft journal seats, which comprises side-by-side, relatively rotatable housings, each comprising a fillet rolling device mounted thereon that laterally spaced and angularly offset fillets can be simultaneously rolled and metal-worked in order to improve their fatigue strength.
  • FIGS 1 and 2 show diagrammatically sections of a metalworking machine 10, which illustrate some basic features of the deep-rolling hardening of the fillets of crankpins 12 of a crankshaft 14 for an internal combustion engine.
  • the crankshaft has a front end 16 which is fixed in a chuck 18 and a flange end 20 which is held by a centering mandrel 22 of the machine.

  • pin seat portions 30, 32 are subjected to high stresses during engine operation, they are reinforced in various ways, e.g. by increasing the pin seat diameter and hard rolling hardening of their laterally spaced, annular fillets F, F ', wherein high and concentrated rolling forces are directed onto the annular fillet areas of the crankshaft.
  • Such rolling creates compressive stresses in the metal of the crankshaft fillets which can, for example, extend to a depth of 4 mm.
  • the upper tool 40 has a pair of oscillating rollers 46, 46 'made of hardened steel or other material, which rotate substantially about mutually inclined axes A and A', with the laterally spaced grooves F, F 'which form the annular contact surfaces form between the pins and the adjacent counterweights or bearing shells of the crankshaft to intervene and roll.
  • the lower tool 41 has angularly spaced support rollers 47 which form bearings and support for the crank pins, while the crankshaft 14 is rotatably driven about its axis B and the fillets are rolled.
  • the rolling pressure is applied hydraulically by the expansion force of a hydraulic cylinder 48 which is operatively connected between the extending ends 49, 50 of the upper and lower claw arms 51, 52 which are rotatably arranged in a central position of the claw arm lengths by a pivot pin 53 held in a fork shoe are.
  • This arrangement provides the mechanical advantage that increases the claw closing force exerted on the claw assembly by the expansion force of the hydraulic cylinder 48.
  • the upper and lower claws and their tools are supported so that they swing about the axis of the rotating crank pins during rolling.
  • the rolling force exerted by the rollers 46, 46 ' can be increased and decreased by the cylinder 48 while the crankshaft is being driven by the engine 24 to introduce concentrated annular internal stress patterns into the metal of the fillets F, F' which occur during engine operation cut surfaces of the crankshaft with the highest load.
  • the size of the pressure as well as the number of rolling processes of the fillets can be selected in order to achieve an optimized fatigue strength.

  • the upper right claw arm 88 is rotatably connected to the lower right claw arm 92 with a central bolt 93 extending in the horizontal direction. This bolt is held by a fork shoe 94, the ends of which extend upward from the lower claw arm to clasp the upper claw arm.
  • This construction provides a right clamp claw assembly 95.
  • the upper left claw arm 90 is similarly connected to the lower left claw arm 97 by a fork shoe and pivot pin 96 to provide a left claw assembly 98.
  • the right and left claw arm fork shoes receive between them the downwardly extending lower portions of the upper claw arms so that the upper and lower claw arms of each pair are coplanar with each other when rotatably connected with bolts 93 and 96, respectively.

  • Each drive cylinder has a cylinder tube in which a piston 120 or 122 is functionally arranged.
  • Controls 123 control the supply and discharge of pressurized fluid to the cylinders below and above the pistons to effect the expansion and contraction strokes of the cylinders so that the forwardly extending claws 124, 126 and 128, 130 close or open the right and left pairs of claw arms.
  • the cylinders and pistons retract, rotating the claw arms about the bolts 93 and 96 so that the claws open Move position away from each other. This allows the tool to be moved to a machining position with the crank pin seats 56, 58 or the crankshaft removed from the tool.
  • Figure 4C illustrates a spaced apart arrangement that holds the relatively movable upper claw arms 88, 90 in parallel and laterally spaced apart.
  • This arrangement includes a headed cylindrical spacer 111 having a cylindrical shaft 111 'that extends axially through a corresponding fine-fit bore 113 in the upper left arm 90 and through a large bore 117 in the right upper arm 88.

  • the processing rollers 190, 192 are in contact through the annular, stepped shoulders 197, 198 of the support rollers 144, 199 of the housings 136, 138 so that the claws, when clamped, as shown in Figure 7, a rolling force on the fillets F, F 'transferred.
  • the bearing unit 162 is arranged between the two housings 136, 138, the side loads S, S 'resulting from the fillet rolling process are effectively neutralized. This ensures that each of the fillets is rolled down in accordance with the requirements and that the tools do not move away from the fillets.
  • the fixed support tool which is attached to the lower claw of each claw assembly, is formed by first and second fixed support units 200 and 202 which are operable e.g. are attached to the lower claw of each lower claw arm by adjustable clamps 204, 206. Since these units are largely of the same construction, only unit 200 will be described in detail.
  • the unit 200 has a generally rectilinear main body 203 with outer grooves 204, 206 which receive the edges of the plate of the lower claw arm 92. Clamps 205 and 207 secure the unit 200 in place on the lower arm.
  • Tool 200 has a pair of spaced rollers 208 and 210 that are rotatably secured by needle bearings 209, 211 on hubs 212, 214 that are supported on laterally spaced side plates 216, 218. Screws 219 secure the side plates to the main body 203.
  • Pneumatic cylinders 222, 224 attached to the cylindrical bracket 74 by clips 226 are used to stabilize the pairs of claw arms.
  • Cylinders 222 and 224 have pistons with connecting rods 228, 230 which extend downwardly and which are pivotally connected to the upper claw arms by brackets 230, 231 to stabilize the operation of the arms when the fillets are rolled.
  • Element 232 is a rotor mounted on rotatable shaft 76 which cooperates with gripper 233 to form a disc brake 234 which can optionally be used to stop the pair of claws in any predetermined position.
  • the crankshaft 54 is inserted into the chuck and the centering mandrel as shown in FIG. 1.
  • the tool from FIGS. 3 to 8 is then moved into a position in which the processing rollers touch the fillets F, F 'of the offset pin seats 56, 58 as shown in FIG.
  • the claws are closed under the load of the expansion cylinder so that the processing rollers 190, 192 engage with the fillets F, F 'with a preselected rolling force.
  • the drive motor 24 is then driven so that the chuck rotates the crankshaft about its axis of rotation, namely the axis B.
  • This rotation causes the offset pin seats 56, 58 to move in a clockwise path or path about the axis B of the crankshaft when the shaft is rotated (see Figure 9).
  • the clamping claws which are clamped to the offset pins, follow the path of rotation of the pins. Accordingly, when the pins rotate about the axis B of the crankshaft, each claw assembly swings and the support arms 78, 78 ', 80, 80' swing back and forth like a pendulum allowing this movement.
  • the rolling force of the claws transmitted to the processing rollers can be increased or otherwise varied in order to effect simultaneous deep-rolling of the fillets and hardening of the metal of the fillet areas and thereby to achieve an improved fatigue strength of the fillets and the crankshaft. Since the crank pins are offset from each other, each set of arms follows its connected crank pins so that the grooves of the crank pin are rolled simultaneously even if they are angularly offset. Appropriate lubricants are applied to the fillet areas during rolling to reduce friction and improve rolling.
  • the drive cylinders are pulled together to open the claws so that the finished crankshaft can be removed from the machine.
