摘要： A bicycle crank fixing structure is arranged to fix a left crank with a mounting bore and a slit extending radially from the mounting bore to a crank axle. The mounting bore is non-rotatably coupled to the crank axle. The slit is provided with two mounting bolts that perpendicularly intersect to adjust a width of the slit to fasten the crank to the crank axle. The crank axle has a retaining hole formed on the outer circumferential surface thereof which faces the slit of the crank. A retaining member with a retaining projection is disposed in the slit such that the retaining member rotates by rotation of the mounting bolt. The retaining projection of the retaining member is retained in the retaining hole formed on the crank axle to prevent the crank from detaching from the crank axle even when a fastening bolt is loosened.

摘要： A bicycle crank arm has a body member and a cover member that at least partially overlies a peripheral surface of the body member. The body member includes a crank axle attachment portion that has a crank axle receiving opening. A slit extends from the peripheral surface of the body member to the crank axle receiving opening. A fastener bore extends transversely through the slit for adjusting the crank axle receiving opening in size. The peripheral surface of the body member has abutments located on opposite sides of the slit. The abutments are arranged relative to the slit such that the abutments move closer together as the crank axle attachment portion is squeezed to decrease the crank axle receiving opening in size. The cover member contacts the abutments and moves with the abutments as the crank axle attachment portion is squeezed to decrease the crank axle receiving opening in size.

摘要： A crank arm is formed with an enclosed hollow section, a first solid end fixed to one end of the hollow section and defining a first opening for fitting to a crank axle, and a second solid end fixed to a second end of the hollow section and defining a second opening for fitting to a pedal. The hollow section is constructed from a middle section having a longitudinal groove and a separate lid fixed to the middle section for enclosing the groove. The first solid end has a thicker cross section than the second solid end so that the stress applied to the crank is substantially constant. The hollow section may be keel-shaped to further enhance the strength of the crank arm without stress being concentrated in any particular location. To form the crank arm, a crank arm body is formed having a first opening on one end for fitting to a crank axle, a second opening on another end for fitting to a pedal, and a longitudinal groove. A lid member is positioned over the longitudinal groove, and then the lid member is welded to the crank arm body. Reverse beads are formed inside the longitudinal groove junctions between the lid member and the crank arm body, and any external beads formed by the welding step are shaved so that a surface of a junction between the middle section and the lid is even with a surface of the middle section and the lid along an entire length of the junction.
摘要翻译：曲柄臂形成有封闭的中空部分，第一实心端固定到中空部分的一端并且限定用于装配到曲轴的第一开口，以及固定到中空部分的第二端的第二实心端，以及限定用于装配到踏板的第二开口。中空部分由具有纵向凹槽的中间部分和固定到中间部分的用于封闭凹槽的单独盖子构成。第一实心端部具有比第二实心端部更厚的横截面，使得施加到曲柄上的应力基本上恒定。中空部分可以是龙骨形的，以进一步增强曲柄臂的强度，而不会在任何特定位置集中压力。为了形成曲柄臂，形成具有一端的第一开口用于配合到曲轴的曲柄臂体，另一端的与踏板嵌合的第二开口和纵向槽。盖构件定位在纵向槽上方，然后将盖构件焊接到曲柄臂主体。在盖构件和曲柄臂主体之间的纵向槽结中形成有反向珠，并且通过焊接步骤形成的任何外部珠被刮削，使得中间部分和盖之间的接合面的表面均匀，中间部分和盖子沿着连接处的整个长度。

摘要： A bicycle crank arm assembly for a bicycle designed for mounting a sprocket thereto. The crank arm has a centrally located hub portion, a crank portion extending radially outwardly from the hub portion and at least three fastening fingers extending radially outwardly from the hub portion. The fastening fingers are designed to have substantially the same stiffness at their free ends. This can be accomplished in a variety of ways such as change the cross-section of the fastening fingers adjacent the crank portion or changing the shape of the sprocket mounting portions of the fastening fingers. Also, in certain embodiments, the fastening fingers adjacent the crank portion are constructed such that their rear surfaces lie in the same plane as the rear surface of the crank portion adjacent thereto, or in a lower plane.

摘要： A crank axle includes an axle body having first and second ends, a first rotary linkage member disposed at the first end of the axle body for nonrotatably fitting a first crank arm thereto, and a first centering structure disposed at the first end of the axle body in close proximity to the first rotary linkage member. If desired, the rotary linkage member may be formed as a plurality of splines, and the same structure may be formed at the second end. A crank arm for fitting to the crank axle includes a crank axle mounting section having a centering structure for centering the crank axle mounting section to an end of a crank axle, and a rotary linkage member for nonrotatably fitting the crank axle mounting section to the end of the crank axle. A special bolt is used to fix the crank arm to the crank axle. The bolt includes a head, a threaded section having a diameter greater than or equal to the head, and a flange disposed between the head and the threaded section. The flange preferably has a diameter greater than the diameter of the threaded section, and the head defines a multiple-sided tool-engaging hole which extends axially into the threaded section to maximize the tool engaging surface. The crank axle mounting section of the crank arm preferably includes a stop ring or similar structure located so that the flange of the bolt is disposed between the stop ring and the first end of the axle body. As a result, the bolt flange presses the crank arm apart from the crank axle when the bolt is loosened. Special tools may be provided to allow easy installation and removal of the components.
