摘要： Segmented sprocket systems and methods for installing the segmented sprocket systems for use in numerous different applications such as, but not limited to, industrial sprockets. The present invention may be a segmented sprocket system including two or more relatively thin sprockets (100) that are installed together on a common hub (200) such that the two or more sprockets form a composite sprocket having a width approximately equal to the sum of the width of the individual sprockets. A segmented sprocket system may include a hub; at least two sprockets having the same outer diameter and an interior opening having a diameter approximately equal to the outer diameter of the hub; wherein the at least two sprockets are positioned on the hub such that each sprocket abuts a neighboring sprocket, thus resulting in a composite sprocket structure.

摘要： A gear-based mechanical metamaterial with continuously adjustable elastic parameters in a large range is provided. The gear-based mechanical metamaterial includes a gear array, a frame and connecting shafts. The gear array is formed by periodically extending mechanical metamaterial cells along an x direction and a y direction. Each of the mechanical metamaterial cells is formed by arranging a multiple gears. Adjacent gears of the multiple gears are meshed with each other. Each of the multiple gears includes a center hole and two centrosymmetric irregularly-shaped holes. A thickness of an elastic arm between the each of two centrosymmetric irregularly-shaped holes and an outer wall of a corresponding one of the multiple gears is uniformly increased or decreased. Each of the connecting shafts is arranged in a center hole of a corresponding one of the multiple gears.

摘要： Separate structural units for an inner gear and a housing of a planetary gear device include an inner gear with a first raised portion formed on the outer peripheral surface of the inner gear, where the first raised portion extends towards in a direction that is inclined with respect to the axial direction of the inner gear. A housing includes a second raised portion formed on an inner peripheral surface, where the second raised portion extends in a direction that is inclined in respect to the axial direction. The housing contains the inner gear such that there is a gap formed between the inner peripheral surface of the housing and the outer peripheral surface of the inner gear. Movement of the inner gear within the interior of the housing is limited through linear contact of the first raised portion and the second raised portion.

摘要： A spur gear includes a radially outer, spur-cut gear rim, a radially inner hub, and a rotationally symmetrical radial connecting structure which integrally connects the gear rim to the hub. The radial connecting structure has mutually spaced struts, which extend between the hub and the gear rim, and axial perforations or holes, which are situated between the struts. The radial connecting structure has a disk-shaped base body, through which the axial holes pass and which has an axial front side and an axial rear side, with the struts being situated on the front side.

摘要： A drive gear used for a fishing reel includes a disc portion having a rotational axis, and a gear tooth protruding from a side surface on an outer peripheral side of the disc portion in a direction in which the rotational axis extends. The gear tooth has a body part and an extended part extending radially inward from the body part. A first angle formed by a cylindrical surface around the rotational axis passing through an axially-outer surface of the body part and a radially-inner surface of the extended part is larger than a meshing pressure angle.

摘要： A device and method for allowing a powertrain gear in an off-road vehicle to be changed to a second powertrain gear having a different number of drive teeth without changing the number of reluctor teeth, by replacing the first powertrain gear with a second powertrain gear having a different number of drive teeth but the same number of reluctor teeth.

摘要： Toothed belt drive with a toothed belt and at least two toothed pulleys, wherein the toothed belt has at least one drive side provided with a toothed profile, the toothed belt wraps around the toothed pulleys over a partial area of their circumference and the teeth of the toothed belt meshingly engage in the tooth gaps of the toothed pulleys, wherein at least one of the toothings on the belt or pulley is formed as a series of tooth pitches varying along the circumference, wherein



the individual tooth pitches are designed to vary by up to a maximum of 5% relative to the mean tooth pitch on the belt or pulley, and
the absolute deviation of a varied tooth pitch from the mean tooth pitch on the belt or pulley is limited by the backlash of the toothing,

wherein the backlash ES results from the difference of the width eS of the tooth gaps of the respective toothed pulley and the width eR of the teeth of the toothed belt in the middle of the tooth height of the teeth of the toothed belt.

摘要： A gear has a gear body made of a first plastic material. The gear body has an axis of rotation, external toothing arranged around an axis of rotation, a centrally located receiving opening, and an intermediate portion located between the external toothing and the wall of the receiving opening. The gear body is fixedly integrally formed on a support body, which is arranged at least partially in the intermediate portion and is made of a second plastic material having a higher stiffness and lower elasticity than the first plastic material, such that surface portions of the external toothing, of the wall of the receiving opening, of the intermediate portion, and of the support body form a substantially flat end face of the gear. The external toothing is helical toothing with teeth which, at least in portions, extend at a helix angle to the axis of rotation.

摘要： A medical device drive system can include a rotational input, a coupling member engaged with the rotational input, a first gear having an engagement feature sized and shaped to engage with the coupling member, and a second gear coupled with the first gear, the second gear coupled to a movable element. The system can have a first system state and a second system state. In the first system state the coupling member is not engaged with the engagement feature and the first gear rotates without moving the coupling member. In the second system state the coupling member is engaged with the engagement feature of the first gear and rotation of the rotational input turns the coupling member, the first gear, and the second gear to move the movable element.
