Abstract:
A link belt for use as a conveyor belt or power transmission belt is provided. The belt is formed of a plurality of links forming a series in successive overlapping relation. The upper surface of each belt link includes an electrically conductive layer. Additionally, the lower surface of each belt link may have an electrically conductive layer. The conductive layer or layers provide an electrical path along the belt to impede the build-up of static electricity as the belt is run during use.
Abstract:
A pulley assembly (30) operable in connection with a tensioner assembly (20) is provided for tensioning a belt. The pulley assembly (30) includes one or more elements for sealing the pulley to protect the pulley assembly in harsh environments. For instance, the pulley assembly may include one or more shields (50,70) for protecting the pulley from contaminants entering the interior of the pulley assembly that can lead to premature failure.
Abstract:
An assembly (10) for maintaining tension in a drive belt features a housing (20) containing a biasing element (70) that exerts torque on an arm (15) connected to the housing. A pulley (7) is connected to the arm and engages a drive belt in response to the bias force of the biasing element on the arm. The pulley deflects the shape of the belt to provide tension in the belt. A sealing element (80) prevents migration of debris into the housing and provides a biasing force to impede translatory movement of a first half (30) of the housing relative to a second half of the housing (40), while allowing rotation of the first half relative to the second half.
Abstract:
A belt (10) having stretch reduction features is provided, along with a method for producing a belt having reduced stretch characteristics. The belt (10) is formed of a jacket (15) and a stretch reduction element (20). The stretch reduction element (20) is formed of a material having a greater modulus of elasticity than the jacket (15). Additionally, the stretch reduction element is formed by bathing the stretch reduction element to a reactive fluid in an oxidizing atmosphere.
Abstract:
An assembly for maintaining tension in a drive belt features a housing mounted on a base. The housing contains a biasing element that exerts torque on the housing to bias the housing in a radial direction. A lever arm is connected to the housing and rotates with the housing in response to the bias of the biasing element. A pulley is connected to the lever arm and engages a drive belt in response to the bias force of the biasing element on the lever arm. The pulley deflects the shape of the belt to provide tension in the belt. In one embodiment, the apparatus allows the user to switch the position of the biasing element and alter the direction of torque on the lever arm. In another embodiment, the lever arm and pulley are removable from the housing and replaceable with other arms and pulleys having different configurations.
Abstract:
A conveyor system having a first conveyor intersecting a second conveyor is provided. A multi-belt transition conveyor assembly is provided at the intersection of the first and second conveyors. The transition conveyor assembly includes a plurality of parallel conveyors of varying lengths. Each belt includes a link belt and a support layer connected to the link belt. The support layer overhangs the link belt and may be comprised of a series of separate elements extending along the length of the link belt.
Abstract:
An assembly for maintaining tension in a drive belt features a housing mounted on a base. The housing contains a biasing element that exerts torque on the housing to bias the housing. An arm is connected to the housing and rotates with the housing in response to the bias of the biasing element. A pulley is connected to the lever arm and engages a drive belt in response to the bias force of the biasing element on the lever arm. The pulley deflects the shape of the belt to provide tension in the belt. In one embodiment, the device includes one or more biasing elements that in a relaxed state have a curved configuration to correspond to the curved configuration of compartments in the housing.
