    摘要: The invention is an improved tensioner for tensioning a power transmission belt. The tensioner is of the type having a track, a carrier mounted in sliding relation with the track with two degrees freedom of movement, a pulley rotatably mounted upon the carrier and for engaging the power transmission belt, a spring biasing the carrier in longitudinal relation to the track, and a damping mechanism that modifies the biasing of the spring based upon movement of the carrier in relation to the track. It is improved by the damping mechanism having a shoe placed in asymmetrical damping relation to the carrier and the track. Further, the shoe includes a first friction bearing surface in mating relationship with a second friction bearing surface of the track.

    摘要: The invention comprises an asymmetric damping tensioner system for belt drives on an engine. A belt is connected between a driver pulley on a crankshaft and any number of driven pulleys. Each driven pulley is connected to an accessory such as an alternator, power steering pump, compressor or the like. The tensioner is placed anywhere before the first component of significant effective inertia, in the belt movement direction. A biasing member in the tensioner is used to maintain a tension in the belt. The tensioner further comprises a damping mechanism to damp belt vibrations caused by the operation of the engine. Tensioner damping friction is unequal or asymmetric, depending upon the direction of movement of the tensioner arm. During acceleration the damping friction of the tensioner in the unloading direction is significantly lower than the damping friction in the opposite, or loading direction, as is the case during deceleration. Lower damping friction during acceleration allows the tensioner arm to quickly adjust to the increase in belt length caused by acceleration. Higher damping friction during deceleration prevents the tensioner arm from being moved too far in the loading direction thereby causing slipping and noise. Asymmetric damping also significantly diminishes overall vibration in the belt during all phases of operation.

    摘要: A synchronous drive arrangement for a printer of the present invention includes a timing belt passed over drive pulleys each being mounted on a particular print drum. The timing belt is made up of two narrow belt parts produced by dividing a single belt. Assuming that the belt parts have n teeth each, one of the belt parts is shifted from the other belt part by one-half of the number of teeth n. The belt parts are so positioned as to cancel each other's eccentricity component during rotation. The arrangement reduces synchronization errors ascribable to the eccentricity of the timing belt while preserving the low-cost configuration of timing belt connection.

    摘要: A tensioner comprises shaft members that mate with each other by way of thread portions. A first shaft member is rotatable with respect to a casing and is restrained from moving in its axial direction. A second shaft member, which is restrained from rotating with respect to the casing, is movable in its axial direction. A torsion spring applies torque in a first direction to the first shaft member. A torque switching member, which can switch frictional torque in association with the rotation of the first shaft member, is provided between the first shaft member and the casing.

    摘要: A device is designed to press the transmission belt of an electric cart and is formed of a pivot set, a first swiveling member, a second swiveling member, a first wheel set, a second wheel set, and an elastic element. The first and the second swiveling members are pivoted with the pivot set such that they are located at two sides of the transmission belt. The first and the second wheel sets are provided with one or more rollers which are pivoted to the first and the second swiveling members. The rollers come in contact with the transmission belt to enhance the transmission effect of the transmission belt. The elastic element provides the first and the second swiveling members with a spring force enabling them to swivel toward the transmission belt.

    摘要: A tensioner having a base. A spring connected to the base biases a plate, having a pulley, toward a belt. Frictional blocks are aligned on the base in a staggered fashion along a spring centerline. The plate slidingly moves in a linear path between the blocks. The blocks constrain the path of the plate allowing movement in only a single axis parallel to a spring axis. A hubload from a belt running on the pulley combined with the spring force acting on the plate creates a force couple acting on the plate through the frictional blocks. The engaging surfaces between the plate and the blocks have a predetermined coefficient of friction thereby creating a damping force as the pulley and plate move in a linear path on the blocks.

    摘要: A tensioner having a pulley journaled to a housing. The housing further comprises a guide. The guide slidingly engages rails on a base. The guide and rails constrain the housing to move in a predetermined linear path. The rails are horizontally offset from two axis defined by the pulley. The pulley load is also vertically offset from the axis of movement of the guide. The guide and rails have a predetermined frictional coefficient so that the cumulative result is an asymmetric damping effect. Further, a linkage is connected between the housing and a camming body. The camming body is rotatably connected to the base. A biasing member such as a torsion spring biases the camming body against the belt load through the linkage. The radius of the camming body is variable to maintain a constant belt load as the tensioner pulley moves in response to a load change.

    摘要: A drive belt tensioning method and assembly using a spring loaded, non-active tensioner. The spring is mounted between a base plate, and a tensioner arm, both of which rotate. A belt tensioning pulley is mounted on the tensioner arm, such that the belt tensioning pulley is adjacent to the drive belt. The tension of the spring causes the tensioner arm to rotate which causes the belt tensioning pulley to tension the drive belt. The spring chosen has a predetermined working length at which the drive belt has the desired tension. Because both the base plate and the tensioner arm rotate, the spring may be kept at this predetermined working length for each belt adjustment. This enables the drive belt to maintain the desired tension. An alignment index integral to the assembly may be used to ensure that the spring is at the predetermined working length.
