Embodiment Construction

[0021] The guide of the invention comprises a ring 1 and a pin 2 combined with an elastically deformable element 3 . For example, the device is adapted to be mounted in a hole in the support O.

[0022] The ring 1 is subjected to surface hardening by diffusion or structural transformation at least at the friction face of the ring 1 with the pin, followed by a finishing treatment and a treatment suitable to reduce the seizure tendency and to reduce the coefficient of friction. For example, diffusion surface hardening can be from nitriding, nitrocarburizing, carbonitriding, surface hardening, chromate passivation. Surface hardening by structural transformation can use high frequency surface hardening. Finishing treatments are, for example, surface oxidation or phosphating followed by impregnation with soluble or bulk oils or application of a coating on the surface suitable for reducing the tendency to seize and for reducing the coefficient of friction and / or corrosion sensitivi...

Abstract

The invention relates to a guiding element in the form of a ring (1) which is used to mount a shaft (2) with friction and with an articulation and / or sliding capability, whereby said element is intended to be mounted in a bore in a support. The invention is characterised in that: the ring and / or the shaft is subjected to a surface hardening treatment, at least at the friction surface thereof, by means of diffusion or structural transformation, followed by a finishing treatment and a treatment designed to reduce seizing tendency and the friction coefficient; the friction surface of the ring (1), formed by the bore (1a) therein, comprises means that can be used to store a lubricant; and the external periphery of the ring is solidly connected to a flexible, deformable element (3) which can be engaged in the bore in the support.

Description

technical field [0001] The present invention generally relates to the technical field of guides. Background technique [0002] A preferred application involves couplings adapted to operate under conditions of high tolerances and shocks and subject to the vibrations of smaller amplitude movements. Couplings of this type may be found, for example, in vehicles (ie trains, wagons, etc.). [0003] These couplings are usually constituted by a guide in the form of a body with a hole (for example a ring) for mounting a pin with a turning and / or sliding function. The body and / or pins may be treated or arranged to avoid wear, seizure and / or corrosion. [0004] The body, for example in the form of a ring, is rigidly mounted in the bore of the component. Due to the movement of the pins and the rigid mounting of the ring, high tolerances, shock or vibration cannot be tolerated. Contents of the invention [0005] An object of the present invention is to overcome these drawbacks in a...
