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 pulley assembly (120) for engaging an endless member (118) includes a first pulley (124), a second pulley (126) and at least one transition segment set (128, 130) comprising one or more transition segments (152, 162a, 162b) that are independently movable between an engaged region and a disengaged region to transition the endless member (118) between the first pulley (124) and the second pulley (126). An actuator system (122) includes a support structure (220), an actuator subassembly (222, 226) secured to the support structure (220) and a stator (224, 228). The actuator subassembly (222, 226) includes a follower (250) and a sled (248), which is movable in a circumferential direction between an advanced position and a retreated position, in response to an electromotive force generated on the sled (248) by the stator (224, 228). The follower engages the cam surface (262) of the sled (248) to move in an axial direction between an extended position and a retracted position as the sled (248) moves between the advanced and retreated positions.

摘要： The present disclosure provides a method for forging a gear capable of preventing burrs from being formed at an edge of the surface opposite to a direction in which a material in external teeth of the material is pushed. A first exemplary aspect is a method for moving the second punch along a tooth profile groove of the guide die to stack the material and the second punch in this order; and pushing the material and the second punch into a tooth profile groove of the tooth profile die in a stacked state to pass them therethrough, in which a tooth pressing part of the second punch covers at least an edge of a region where external teeth are formed on a surface of the material on the first punch side.

摘要： A sprocket assembly for a bicycle includes at least one alignment member configured to align components of the sprocket assembly about a rotation axis. The alignment member interacts with an engagement member to axially engage components of the sprocket assembly. The engagement member may be configured with features to stop rotation relative to components of the sprocket assembly.

摘要： A transmission device for installation on a driveshaft, having a base body which encloses the driveshaft, a pinion which in the mounted state is arranged in the base body and on the driveshaft, and a rack which interacts with the pinion and runs through the base body. The transmission device is distinguished by the fact that the base body is open on one side in such a way that it can be fitted onto a driveshaft in the radial direction, and in that the pinion is in multiple parts such that it is possible to perform a mounting process on the driveshaft during which the parts of the pinion can be joined together by a radial movement with respect to the driveshaft.

摘要： A method for repairing a gear (2) having a number of damaged teeth (4, 4′, 4″), wherein the method comprises the step of removing material from the gear (2) hereby providing a pocket structure (28, 28′, 28″, 28′″), wherein said material includes at least one damaged tooth (4, 4′). Said method further comprises the step of providing a segment (12, 12′, 12″, 12′″) to be inserted into the pocket structure (28, 28′, 28″, 28′″), wherein the segment (12, 12′, 12″, 12′″) has a geometry that fits the geometry of the pocket structure (28, 28′, 28″, 28′″). The method comprises the step of radially inserting the segment (12, 12′, 12″, 12′″) into the pocket structure (28, 28′, 28″, 28′″) and attaching radially extending attachment structures (60, 60′) through at least a portion (18, 18′) of the segment (12, 12′, 12″, 12′″) and further into at least a portion (32, 32′) of the underlying structure (64) of the gear (2).
