Abstract
A planer (10), in particular a hand held planer for machining wood, with a planer housing (12), which includes a planer shaft (20), supported rotatably in at least one direction with an outer contour (23), which in a longitudinal groove (46) has at least one planer blade (21), which is braced on a centrifugal wedge (56) that can be prestressed with a spring (54) or the like can be produced more simply and economically in that the centrifugal wedge (56) is fastened to the planer shaft (20), elastically movably relative to it, in captive fashion solely by the spring (54), in particular being removable without destruction, and substantially without touching the planer shaft (20).
Claims27
A hand held planer for machining wood, comprising a planer housing;
- a planer shaft accommodated in said housing rotatably in at least one direction and having an outer contour located inside a flight circle, said planer shaft being provided with at least one longitudinal groove;
- at least one planer plate arranged in said at least one longitudinal groove;
- a centrifugal wedge bracing said at least one planer blade;
- a spring prestressing said centrifugal wedge, said centrifugal wedge being secured elastically movably to said planer shaft in captive fashion solely via said spring, and being non-destructively removable substantially without touching said planer shaft.
A planer shaft for a planer, comprising a planer shaft body which is rotatable in at least one direction and having an outer contour located inside a flight circle, said planer shaft body having at least one longitudinal groove for insertion of at least one planer blade braceable on a centrifugal wedge which is prestressable by a spring and securable elastically movably to said planer shaft body in captive fashion solely via said spring and also is non-destructively removable without touching said planer shaft body.
