    摘要: The invention discloses a method of manufacturing an assembled shaft, comprising the following steps:

    at least one of a step of expanding the inner diameter of at least a joining portion of a first shaft element and a step of reducing the outer diameter of at least a joining portion of a second shaft element;
    positioning the joining portion of the first shaft element around the joining portion of the second shaft element;
    welding the first shaft element and the second shaft element by forcing a current flow through the first shaft element and the second shaft element; and
    at least one of a step of reducing the inner diameter of at least the joining portion of the first shaft element and a step of increasing the outer diameter of at least the joining portion of the second shaft element.

    摘要: A transmission shaft of a countershaft-type manual transmission is constructed from a plurality of hollow shaft portions which are butt press welded to one another, at least two of which hollow shaft portions are provided in each instance with at least one helical toothing of a fixed wheel of a spur gear stage. The hollow shaft portions provided with a helical toothing are connected to the respective adjacent hollow shaft portion in each instance so as to be rotated by a correction angle (Δα) around their center axis in proportion to a deviation (Δx) from their axial target position, wherein the ratio between the correction angle (Δα) and the axial deviation (Δx) corresponds to the pitch (s) of the helical toothing (Δα/Δx=s).

    摘要: A method for manufacturing a torque-transmitting assembly includes: turning an inner component (b) machining an outermost surface of the inner component such that the outermost surface of the inner component has a continuous convex shape; (c) turning an external component; (d) machining an innermost surface of the external component such that the innermost surface of the external component has a continuous convex shape; (e) heating the innermost surface of the external component to expand a size of the innermost surface after machining the innermost surface of the external component; (f) placing the heated external component onto the inner component while the inner component is maintained at room temperature; and (g) holding the inner component and the external component in place until an interface between the innermost surface of the external component and the outermost surface of the inner component reaches the room temperature.

    摘要: A mechanical joint for transferring rotational motion between shafts at an angle and related assemblies. The assemblies can include both fixed and adjustable-angle joint housings for providing high torques in hard to reach areas. Other assemblies include improvements in inboard marine drives that correct the prop angle to generally align with the direction of travel of the boat and outboard marine drives with improved drive trains.

    摘要: A connecting device for a chainring of a bicycle is disclosed, including a connecting disc, a shaft, and a crank. The connecting disc is adapted to be engaged with a chainring, and has an axial bore, a bulging portion bulging from a central portion of the connecting disc, and a surrounding portion, which is flat, and surrounds an outer periphery of the bulging portion. The shaft passes through the axial bore to be fixedly engaged with the connecting disc. The shaft has a connecting end. The crank has a connecting end engaged with the connecting end of the shaft, and a bearing end adapted to bear an external force to make the crank rotate around the shaft. Whereby, the amount of materials used to make the connecting device is decreased. At the same time, the manufacturing cost, the size, and the weight of the connecting device are all reduced.

    摘要: A drive shaft includes a first shaft member made of metal, a tubular member made of CFRP, and a first exterior sleeve. The first shaft member is capable of being attached on one end side thereof to a first constant velocity joint, and has a first serrated part on which serrations are formed on another end side thereof. The tubular member is formed with a first fitting part fitted externally over the first serrated part. The first exterior sleeve covers the first fitting part by being disposed to extend over outer circumferential surfaces of the first shaft member and the tubular member. A film provided with a bonding assistance region and an adhesive are interposed between the outer circumferential surface of the tubular member and the inner circumferential surface of the first exterior sleeve.

    摘要: A transmission shaft assembly includes a carbon-fiber tube having two ends, and each end has protrusions and recesses which are located alternatively to the protrusions. Two connectors each have an outer tubular portion and an inner tubular portion extending axially therefrom. Multiple first engaging portions and multiple second engaging portions are located between the outer tubular portion and the inner tubular portion of each of the connectors. The two connectors are respectively connected to the two ends of the carbon-fiber tube. The first engaging portions are engaged with the recesses, and the second engaging portions are engaged with the protrusions. Adhesive is applied between the connectors and the carbon-fiber tube.
