  • Publication number: 20200149610
    Abstract: An element of a transmission including: a rocking edge portion with a convex surface formed on one of a front face and a rear face, so that the rocking edge portion extends over a pillar portion at least partially, the rocking edge portion having a contact line where the adjacent elements contact each other serves as a fulcrum of rotation of the adjacent elements; and a recessed non-contact portion extends along the saddle surface, to avoid contact with the adjacent element, and that divides the rocking edge portion in the width direction at least partially. A depth of the non-contact portion is set so that an end portion of the non-contact portion is positioned on an inner peripheral side of the transmission belt relative to the contact line when a winding radius is minimized, and the end portion does not reach the trunk portion on the inner peripheral side.

  • Publication number: 20200109765
    Abstract: An element for a transmission belt that is wound around a primary pulley and a secondary pulley of a continuously variable transmission includes: a trunk portion having a saddle surface that is in contact with a ring of the transmission belt; and a pair of pillar portions extending from the trunk portion so as to be positioned on both sides of the saddle surface in a width direction. The saddle surface is a convex surface that is formed by an elliptic arc and satisfies b/a?0.015 when a long diameter of the elliptic arc is regarded as “a” and a short diameter of the elliptic arc is regarded as “b”. In this way, it is possible to optimize the stress distribution of the ring that is in contact with the saddle surface and improve the durability of the ring and the transmission belt.

  • Publication number: 20200072461
    Abstract: This solid fuel burner is provided with: a venturi tube in which a channel for mixed fluid in a fuel nozzle narrows toward the center in the channel cross section; a fuel concentrator that imparts, to the mixed fluid, a velocity component away from the center of the fuel nozzle; and a channel separation member that separates the channel of the fuel nozzle into an internal side and an external side; wherein the channel separation member is shaped in such a way that the cross sectional area of an external channel is larger at the downstream end than at the upstream end, and the upstream end of the fuel concentrator is located between the upstream end and the downstream end of an expanded portion of the venturi tube. This solid fuel burner prevents solid fuel particles, which is ground biomass fuel, from adhering and depositing inside the nozzle.

  • Publication number: 20200011398
    Abstract: In an element of a power transfer belt to be wound around a primary pulley and a secondary pulley of a continuously variable transmission to transfer torque, the distance from a boundary line between a surface positioned on the outer peripheral side of the power transfer belt with respect to a rocking edge portion and the rocking edge portion to a saddle surface is determined from the slip amount due to micro slip which is relative slipping between the element and the primary pulley caused when the primary pulley pushes out the power transfer belt toward the secondary pulley, and the angular speed of the element and the angular speed of a ring in a range in which the power transfer belt is wound around the secondary pulley.
