摘要： A rotary drill bit having a plurality of cutters, each rotatably mounted on a trunnion. The bearing support includes a friction bearing consisting of a cup member of half-moon shape preferably made of an oil soaked sintered material. The outer surface of the cup engages the bore of the cutter and forms the non-loaded part of the slip surface in the unloaded zone of the friction bearing. The cup is mounted in a manner retaining the cutter against axial displacement from the trunnion. Biasing means between the cup and trunnion presses the cup against the cutter bore and compensates for wear of the cup.

摘要： A clutch release device has a pressure plate mounted on a sliding sleeve, and a stationary ring of a bearing abut one side of the pressure plate. A clutch lever abuts the other side of the pressure plate, and is held from axial removal by a ring having a flexible outer rim. The holding ring is held to the pressure plate by a flange on the sliding sleeve. The clutch lever has a central aperture fitted over a central conical portion of the pressure plate, the aperture having a pair of inwardly directed projections. The outer diameter of the holding ring is greater than the distance between the facing ends of the projections.

摘要： A rotary drill bit having a drill bit body and at least one trunnion projecting from the drill bit body and a rotary cutter supported on at least one pair of radial rolling bearings on the trunnion. The rolling elements of at least one bearing are guided on at last one axial end facing the drill bit body in an outer bearing race groove incorporated in the bore of the rotary cutter. The inner bearing groove is formed on the trunnion for the rolling elements of the radial roller bearing. A filling opening is provided for assembly of the rolling elements comprising a channel which extends through the drill bit body and trunnion and is essentially axially oriented having one terminal end adjacent the inner bearing race groove and at least one filler piece for sealing the opening. The filling opening is arranged to provide a common filling means for each radial bearing.

摘要： The present invention is a method for the manufacture of bearing rings ruptured along an arrow-shaped partition line for antifriction bearings or similar devices. According to the invention a radial bore is introduced through the middle of the ring transversely of the bearing axis, and in the opposite end faces are introduced V-shaped notches which are displaced in relation to the radial bore in a circumferential direction. The bearing ring is supported on one end and ruptured first on that end by a force directed against the opposite end. The ring is turned over and again ruptured similarly until an arrow-shaped partition line extends from the radial bore to the notches.
