Abstract
In a conventional impact generator, a grease receives centrifugal force by the rotation of a rotary member, thereby keeping away from surfaces of the rotary member and a weight. Consequently, insufficient lubrication is caused between the weight and a member (for example, a tappet and the like) which comes in contact with the weight. An impact generator D comprises an impregnating member 60 capable of impregnating the grease. The impregnating member 60 is extended from a vicinity of an inner peripheral wall surface 59 of a chamber E1 for accommodating a rotary member 10 and a weight 30 to a position where the impregnating member 60 comes in contact with the weight 30 performing a circular motion.
Claims3
An impact generator comprising:
- a rotary member for being rotated upon receipt of rotating force;
- a weight movably held by the rotary member for performing a circular motion for striking a struck member;
- and
- an impregnating member capable of impregnating a grease,
- wherein the impregnating member is extended from a vicinity of an inner peripheral wall surface of a chamber for accommodating the rotary member and the weight to a position where the impregnating member comes in contact with the weight performing a circular motion.
