Abstract: A guide member has a ring for mounting a pin with friction and articulation and/or sliding capacity. The member is adapted for mounting in the bore of a support. The ring and/or the pin is subjected, at least at its friction surface, to a surface hardening treatment by diffusion or by structural transformation, followed by finishing surface treatment for reducing the tendency to jamming and to reduce the friction coefficient. The friction surface of the ring, comprising its bore, has arrangements acting as a lubricant reserve. The outer periphery of the ring is joined to an element made from a deformable flexible material suitable for being engaged in the bore of the support.

Abstract: A greased joint assembly operating in oily conditions comprises an axle mounted rotating or pivoting in a ring. The axle and/or the ring are subjected to a hardening surface treatment by diffusion or by structural transformation followed by a finishing surface treatment and a treatment suitable for reducing the tendency to jamming and for reducing the sensitivity to corrosion, and the bore of the ring and/or the axle is provided with arrangements acting as a lubricant reserve.

Abstract: A self-lubricating guiding element which is characterized in that the body thereof is made from a material with high resistance to wear and/or seizing and corrosion. Each of the ends of the bore in the body is equipped with at least one groove which is intended to prevent the lubricant from leaving the friction zone. In addition, the bore comprises oriented slots, at least between the grooves, which open into at least one of the grooves and which are used to store lubricant.

Abstract: This guide member in the form of a ring (1) for mounting a pin (2) with friction and articulation and/or sliding capacity, the member being suitable for mounting in the bore of a support, is characterized in that: the ring and/or the pin is subjected, at least at its friction surface, to a surface hardening treatment by diffusion or by structural transformation, followed by finishing surface treatment for reducing the tendency to jamming and to reduce the friction coefficient; the friction surface of the ring (1), consisting of its bore (1a), has arrangements suitable for acting as a lubricant reserve; the outer periphery of the ring is joined to an element made from a deformable flexible material (3) suitable for being engaged in the bore of a support.

Abstract: The assembly operating in oily conditions comprises an axle (2) mounted rotating or pivoting in a ring. The axle (2) and/or the ring (1) are subjected to a hardening surface treatment by diffusion or by structural transformation followed by a finishing surface treatment and a treatment suitable for reducing the tendency to jamming and for reducing the sensitivity to corrosion, the bore of the said ring and/or the axle having arrangements for acting as a lubricant reserve.

Abstract: The invention relates to a self-lubricating guiding element which is characterised in that the body (1) thereof is made from a material with high resistance to wear and/or seizing and corrosion. According to the invention, each of the ends of the bore (1a) is equipped with at least one groove (1b) and (1c) which is intended to prevent the lubricant from leaving the friction zone. In addition, the bore (1a) comprises oriented slots (1d), at least between the grooves (1b) and (1c), which open into at least one of said grooves and which are used to store lubricant.

Abstract: An instrument for measuring a muscular force particularly suited for the re-education and/or development of a muscle belonging to an upper and/or lower limb of the human body. A linearly displaceable element is coupled to a displacement device operable to continuously reciprocate the element with adjustable speed and travel. The displacement element is mounted such that a part of the human body can exert a muscular force (F1) upon the element. For example the element can be formed with one or more impressions to create an artificial climbing grip. The displacement device is coupled to a control center capable of, displaying a force threshold corresponding to a force of defined and variable intensity, operating the displacement device if the intensity of the force exerted on the element (F1) is greater than or equal to the displayed threshold value, measuring the force supplied, measuring the displacement, speed and travel of the element, measuring the duration of the force (F1).
