A pulley device for supporting a belt of a chain tensioning idler or a runner roller includes a bearing having an outer ring mounted for rotation relative to a coaxial inner ring and first and second C-shaped pulley parts mounted on the radially outer surface of the outer ring with their openings facing each other. The radially outer portion of the first and/or second pulley part includes at least one radial through opening, and a first portion of at least one of the pulley parts radially inward of the through opening is deformable from a first configuration in which the first pulley part is axially movable relative to the outer ring to a second configuration in which the first pulley part forms an interference fit with the outer ring or with the second pulley part. Also a method of connecting the pulley parts to the outer ring.

A pulley device provides a pulley and a bearing. The pulley has at least one C-shaped pulley part having an inner portion mounted on the bearing, an outer portion having an outer cylindrical surface dedicated to interact with a belt or a chain, and an intermediate portion extending substantially radially between axial ends of inner and outer portions on one axial side of pulley device. The outer cylindrical surface of outer ring is provided with at least one material deformation forming an axial stop for the pulley.

A pulley device for supporting a belt of chain tensioning idler or a runner roller includes a bearing having an outer ring mounted for rotation relative to a coaxial inner ring and at least one pulley part that is C-shaped in cross section. The pulley part has an inner portion with a frustoconical inner surface mounted on an outer cylindrical surface of the outer ring, an outer cylindrical portion having an outer cylindrical surface configured to support a belt or a chain, and an intermediate portion extending radially inward from the cylindrical outer portion to the inner portion. The pulley part is integral and has an open end on an axial side opposite the intermediate portion. The frustoconical surface extends inwardly towards the outer ring, and the inner surface is force fitted onto the outer cylindrical surface of the outer ring.

The present disclosure relates to a belt driven system. The belt driven system may include a master pulley, a slave pulley, a belt around the master pulley and the slave pulley, a tension pulley configured to tension the belt, and a position adjusting device configured to automatically adjust a position of the tension pulley based on an interaction of the tension pulley and the belt.

A Pulley device for a tensioning or winding roller for a transmission element including a pulley, and a rolling bearing provided with a rotating outer ring, the pulley being mounted on an outer surface of the outer ring, a fixed inner ring, the rings being coaxial and forming a radial space between them, and at least one row of rolling elements arranged in the radial space. The pulley device further includes at least one annular protection flange with a radial body. The flange is fixed to the rotating outer ring by crimping an axially protruding portion of the pulley towards an outer edge of the flange.

A debucking machine, for use with processing industrial hemp or cannabis, is provided. Embodiments of the debucking machine include counter-rotating rollers equipped with rubberized combs for gently removing flowers, or buds, from harvested industrial hemp or cannabis. Embodiments of the debucking machine are portable and may be moved from location to location within a drying shed.

Tensioner systems, methods and apparatus are described for tensioning drive belts of vibratory screens.

A method and apparatus that circumvents belt path obstacles in a Corvette C8 engine for transferring auxiliary power from the engine crankshaft output pulley to a supercharger input pulley by using a drive path transfer apparatus including a transfer input pulley located in the same plane as the crankshaft pulley and connected to it with the main drive belt, a transfer output pulley in a second plane spaced inboard of the first plane including the supercharger pulley, a secondary belt joining the transfer output pulley and the supercharger pulley, and a coupling shaft having the transfer input pulley at one end and the transfer output pulley at the other end, the coupling shaft being rotationally mounted in a two-piece installable bracket secured on the engine block in a location to the side of the obstruction, thereby transferring power from the engine to the supercharger without interference from the obstruction.

To provide a vehicle body structure for an autonomously traveling vehicle that is distinguished for maintainability. A vehicle body structure (1) for an autonomously traveling vehicle that travels on wheels (3) provided on a chassis (2) includes side frames (4R), (4L) that extend in a chassis longitudinal direction on both sides of the chassis with respect to a chassis width direction, first drive units (20) in each of which a drive motor (5) that is for driving the wheel (3), a reduction gear (6), and a drive shaft (7) that drives the wheel (3) are integrally configured, and second drive units (30) which each rotatably hold a drive shaft (7) that drives the wheel (3). The vehicle body structure (1) is characterized in that the first drive units (20) and the second drive units (30) are each provided so as to be integrally mountable in and dismountable from the same side frames.
