A frictional power transmission belt is provided, containing an adhesion rubber layer in contact with at least a portion of a tension member extending in a longitudinal direction of the belt, in which the adhesion rubber layer is formed of a first vulcanized rubber composition containing a rubber component and a filler, the filler contains substantially no silica and contains 30 parts by mass or more of carbon black based on 100 parts by mass of the rubber component, and the tension member has, on a surface thereof, an overcoat layer formed of a second vulcanized rubber composition containing a rubber component and silica.

Friction transmission belt

The present invention pertains to a frictional power transmission belt including a tension member extending in the longitudinal direction of the belt and an adhesion rubber layer in contact with at least a portion of the tension member, in which the adhesion rubber layer is formed of a vulcanized rubber composition containing a rubber component, short fibers having an average fiber diameter of 2 &#x3bc;m or more, and a filler.

Friction drive belt

The present invention relates to a transmission belt containing a core wire extending in a lengthwise direction of the belt, an adhesive rubber layer in contact with at least a part of the core wire, a back surface rubber layer formed on one surface of the adhesive rubber layer, and an inner surface rubber layer formed on the other surface of the adhesive rubber layer and engaging or in contact with a pulley, in which the adhesive rubber layer is formed by a vulcanized rubber composition containing a rubber component, a fatty acid amide and a silica.

Transmission belt

The present invention relates to a power transmission belt provided with a tension member, a tension member-supporting layer, a tension rubber layer, and a compression rubber layer, the belt having a plurality of cog portions, in which the tension member is formed of an aramid fiber, the compression rubber layer is formed of a vulcanized rubber composition containing a rubber component and aramid short fibers embedded in the vulcanized rubber composition with being arranged in a width direction of the belt, the power transmission belt has a strain of from 0.5 to 0.8% when compressed under a stress of 2.0 N/mm2 in the width direction, and the power transmission belt has a strain of from 0.35 to 0.7% when pulled under a load of 2 kN in the lengthwise direction.

Transmission belt and belt-speed-change device

The present invention relates to a frictional power transmission belt containing an extensible layer to form a belt back surface, a compressive layer formed on one surface of the extensible layer and having a power transmission surface at least a part of which can be in contact with pulleys, and a tension member embedded between the extensible layer and the compressive layer along a belt length direction, in which at least the compressive layer is formed of a rubber composition containing a polymer component, short fibers and a surfactant and in which the short fibers contain at least short fibers of water-absorbing fibers.

Frictional power transmission belt

The present invention relates to a V-ribbed belt to be wound around plural pulleys and used, including an extension layer that forms a back surface of the V-ribbed belt, a compression layer provided on one surface of the extension layer and having plural ribs extending parallel to each other along a longitudinal direction of the V-ribbed belt, and a load carrying cord embedded between the extension layer and the compression layer along the longitudinal direction of the V-ribbed belt, in which a distance from an outer peripheral portion of the load carrying cord on the rib side to a tip portion of the rib is from 2.0 to 2.6 mm, and a distance from the outer peripheral portion of the load carrying cord on the rib side to a bottom portion of the rib is from 0.3 to 1.2 mm.

V-ribbed belt

The present invention relates to a power transmission belt containing a tension member extending in a belt lengthwise direction, an adhesion rubber layer in contact with at least a part of the tension member, a compression rubber layer formed on one surface of the adhesion rubber layer, and a tension rubber layer formed on other surface of the adhesion rubber layer, in which the compression rubber layer is formed of a vulcanized rubber composition containing a rubber component, a polyolefin resin and a reinforcing material, the rubber component contains a chloroprene rubber, and the reinforcing material contains a short fiber.

A vortex flowmeter including a shell member having an inlet and an outlet which are opened in the side wall thereof, a filter element provided in the shell member to define two, upper and lower, chambers inside the shell member and also isolate the inlet and the outlet from each other, a duct connected to the shell member in such a manner as to communicate with the outlet, and a vortex generating device provided inside the duct. A tubular projection is provided at the outlet in such a manner as to extend into the shell member, the projection being tapered toward the outlet, thereby correcting the flow of air flowing into the outlet so that the velocity distribution of air streams inside the duct becomes uniform.
