A cone to which one or several torque transmitting member(s) are attached as to form at least one torque transmitting arc on the surface of the cone. The torque transmitting member(s) will be used for torque transmission between at least one rotational energy conveying device and the cone. The torque transmitting member(s) are attached in a manner such that significant circumferential sliding that occurs between the torque transmitting surface(s) of the torque transmitting member(s) and the torque transmitting surface(s) of the rotational energy conveying device(s) when the pitch diameter of the torque transmitting member(s) is changed can be eliminated, such that wear and frictional energy losses are significantly reduced, and positive engagement devices, such as teeth, can be used for torque transmission between the torque transmitting member(s) and the rotational energy conveying device(s). The cone with torque transmitting member(s) can be used to construct various Continuous Variable Transmissions that have a long life, low frictional energy losses, and can be made non-friction dependent.

A method and apparatus for measuring a size of a load in a basket that is rotatably supported is presented. The method comprises determining an acceleration energy (AE) required to accelerate the basket; determining a friction energy (FE) required to maintain a stable rotational speed of the basket; subtracting the friction energy (FE) from the acceleration energy (AE) to obtain a load inertial energy (LE); and determining a load size from the load inertial energy (LE).

Cones or cone assemblies with one or two oppositely positioned torque transmitting devices, such as torque transmitting arcs of constant pitch (formed by torque transmitting members) or teeth. The torque transmitting devices will be used for torque transmission between at least one means for coupling, such as transmission belt or chain, and a cone or cone assembly. The cones or cone assemblies can be used to construct CVT's for which significant circumferential sliding between the torque transmitting surfaces of the torque transmitting devices and the torque transmitting surfaces of the means for coupling engaged to them due to change in pitch diameter can be eliminated, as to reduce wear and frictional energy loses typical in similar devices of prior art and allow the usage of positive engagement devices, such as teeth, in coupling the torque transmitting devices with their means for coupling. CVT's that consist of at least one cone or one cone assembly of this invention that is coupled by a means for coupling to at least one means for conveying rotational energy, such as a pulley, a sprocket, a cone assembly of this invention, or a cone of this invention. Adjuster systems that can increase the performance of the CVT's of this invention and other CVT's that suffer from either or both transition flexing and a limited duration at which the transmission ratio can be changed, so that efficient non-friction dependent CVT's and efficient friction dependent CVT's that do not suffer from transition flexing and / or a limited duration at which the transmission ratio can be changed can be constructed.

A damping mechanism (1) that generates a damping force in response to a liquid flow between a first liquid chamber (R1) and a second liquid chamber (R2) comprises a partitioning member (2) separating the first liquid chamber (R1) and the second liquid chamber (R2) and a flow passage (P) formed in the partitioning member (2) to connect the first liquid chamber (R1) and the second liquid chamber (R2). The flow passage (P) comprises an odd number of through-holes (10-14) greater than three which penetrate the partitioning member (2) and are connected in series. A large amount of frictional energy loss due to a long path length occurs in the flow passage (P) and causes the damping mechanism (1) to generate a sufficient damping force.

A method of recognizing a conveyor belt wear condition is provided. Relationships between an apparent compressive stress in a wear resistance test and surface roughness of a sample and between the surface roughness and amount of wear per unit frictional energy of the sample are acquired. A wear condition of an upper cover rubber is recognized based on an apparent compressive stress generated on the upper cover rubber at a use site, and a database is created based on the relationships. Alternatively, relationships between an average wear pitch calculated from the surface roughness and viscoelastic properties of the sample and between the average wear pitch and an actual amount of wear of the sample are acquired. A wear condition of the upper cover rubber is recognized based on the viscoelastic properties of the upper cover rubber of the use site and a database is created based on the relationships.
