Abstract
An improved apparatus for roll forming tooth profiles on workpieces is provided with an adjusting means for adjusting the root angle of a workpiece. The adjusting means is designed to withstand the large forces generated with equipment of this type and can be used in combination with a separate means for pivotally moving a die and a workpiece relative to one another for bringing the die and the workpiece into and out of meshing engagement.
Claims9
In apparatus for roll forming tooth profiles on a workpiece by bringing a die and a workpiece into rolling engagement with each other with sufficient force to displace material on said workpiece, said apparatus being of a type which includes a first spindle means for carrying a gear member and a second spindle means for carrying a pinion member for meshing with said gear member, with one of said gear member and said pinion member being a die for forming tooth profiles on a workpiece and the other of said gear member and said pinion member being the workpiece, the improvement comprising:
- a machine frame,
- first mounting means for mounting said first spindle means within said machine frame so that said first spindle means can be moved about a pivot axis which intersects the axis of rotation of said second spindle means to thereby provide for a pivotal feed motion of the gear member relative to the pinion member,
- second mounting means for mounting said second spindle means in said machine frame for limited pivotal movement about an axis which is parallel to the pivot axis of said first spindle means,
- adjusting means operatively associated with said second spindle means for adjusting and fixing the angular relationship of said spindle means to thereby provide for a root angle adjustment of the tooth profiles being roll formed on a workpiece.
In apparatus for roll forming tooth profiles on a workpiece by bringing a die and a workpiece into rolling engagement with each other with sufficient force to displace material on said workpiece, said apparatus being of a type which includes a first spindle means for carrying a gear member and a second spindle means for carrying a pinion member which can be brought into meshing engagement with the gear member, with one of said gear member and said pinion member being a die for forming tooth profiles on a workpiece and the other of said gear member and said pinion member being the workpiece, the improvement comprising
- adjusting means operatively associated with one of said spindles for adjusting the root angle between the pinion member and said gear member, said adjusting means including:
- a wedge-shaped member which is axially movable against a fixed portion of the apparatus to establish a stop surface against which a movable portion of the apparatus can be moved to thereby provide an adjustment of an associated spindle means about a pivot axis, and
- displacing means for moving said wedge-shaped member out of its operative position to thereby release said stop surface and to permit disengagement of a pinion member and a gear member.
In apparatus for roll forming tooth profiles on a workpiece by bringing a die and a workpiece into rolling engagement with each other with sufficient force to displace material on said workpiece, said apparatus being of a type which includes a first spindle means for carrying a gear member and a second spindle means for carrying a pinion member which can be brought into meshing engagement with the gear member, with one of said gear member and said pinion member being a die and the other of said members being the workpiece, the improvement comprising
- root angle adjusting means operatively associated with one of said spindle means for establishing an adjustable stop surface against which the associated spindle means can be positioned during a rolling operation, said root angle adjusting means being located near the working end of its associated spindle means so as to prevent loss of precision setting from bending moments of said spindle means.
