摘要： A Hookes universal joint assembly which, in a preferred embodiment, comprises two series connected universal joints to produce an angle change of 60.degree. to 70.degree.. A rigid housing confines input and output rotating drive shafts. In a preferred embodiment the yokes and cross members are formed as flat steel plates with tab-into-notch engagements. A method to retain an input shank and an end linkage to a drive shaft is disclosed. End linkages have parallel extending legs where the legs have protruding bumps at a distal end to engage exterior notched slots of input and output drive shafts. The drive shafts are identical in structure. An input shank is permanently held in a recess of the input drive shaft by engagement of a rib of the housing into a groove around the input shank.

摘要： A drill bit for drilling subterranean formations includes a device to provide a "universal" effect between the shank and crown for self alignment of the crown with the bore hole in the formation. The bit is suitable for downhole assemblies configured for straight drilling, directional drilling and navigational drilling. The device can be incorporated into both drag bits and roller-type "rock" bits. Preferred embodiments include a flexible sub connecting the crown to the shank portion and having reduced stiffness relative to the drill string. Alternatively a spherical universal joint or trunnion type universal is used. Replaceable lugs increase durability and reliability of the universal. The device equalizes the loads on cutters while reducing wear, average loads, and impact loads on cutters. Bore hole diameter and chatter of the bit in the bore hole are reduced, promoting maximum efficiency and rate of penetration as wobble and precession are minimized.
摘要翻译：用于钻探地下地层的钻头包括在柄和冠之间提供“通用”效应的装置，用于使冠部与地层中的钻孔自对准。该钻头适用于直井钻井，定向钻井和导航钻井的井下组件。该装置可以并入拖曳位和滚子式“摇滚”位。优选实施例包括将冠部连接到柄部分并且相对于钻柱具有降低的刚度的柔性子部分。或者，使用球形万向接头或耳轴式通用型。可更换的凸耳增加了通用的耐用性和可靠性。该装置使刀具上的负载相等，同时减少刀具上的磨损，平均载荷和冲击载荷。钻孔中的钻孔直径和钻头的颤动减小，从而在摆动和进动最小化的同时提高最大效率和穿透速度。

摘要： A flexible coupling for use in a down-hole motor assembly such as a positive displacement moineau motor is presented. The flexible coupling includes two sets of flexible joints. Each joint consists of two cylindrically shaped slipper couplings angularly offset by 90 degrees. Each slipper coupling is comprised of mating male and female members which are joined together by ball bearings positioned in arcuate grooves located along the cylindrical mating surface.

摘要： A universal joint includes a first shaft member having a cylindrical portion, a pair of yoke portions at a free end thereof and a ball-like portion formed between the yoke portions and a second shaft member having a cylindrical portion and a pair of yoke portions at a free end thereof. The ball-like portion is formed integrally and inseparably with the yoke portions of the first shaft member. The first and second shaft members are thus detachably and movably connected with each other through engagement between the ball-like portion of the former and the yoke portions of the latter.

摘要： The torque transmission shaft has a shaft having a hollow tubular shape and a clamp. The shaft has a connecting portion integral with the shaft at one axial end portion, a slit extending in the axial direction in a portion on the other axial end side and opens on the other side in the axial direction, and a female serration on the inner circumferential surface of the other axial end portion. The clamp is separate from the shaft and has a non-continuous portion at one location in the circumferential direction, a pair of flange portions on both sides of the non-continuous portion, and a connecting portion connecting the pair of flange portions in the circumferential direction. The clamp is externally fitted and fixed to the other axial end portion of the shaft and reduces the diameter of the other axial end side portion of the shaft.
