CS242958B1 - Device for universal swinging clamping of cylindrical parts - Google Patents

Abstract

The device for a swing bearing is intended, for example, for mounting linear hydraulic motors, with the main purpose being to simplify the design of a versatile swing bearing and to prevent permanent deformations and failures of components, especially where axial forces do not always act in defined planes. The swing bearing consists of two rings, slid onto the clamped cylindrical object, tightened against each other by screws in conical recesses of a counter ring with an outer diameter formed as part of a spherical surface, consistent with the inner spherical surface of two flanges, spaced apart by washers on the fastening screws to a fixed structure. The function of the described bearing is as follows: by tightening the inner rings against each other with screws, the cylindrical component is secured against axial displacement by friction. The outer spherical surface of the counter ring rests against a part of the inner spherical surfaces of the flanges attached to a fixed structure, while the thickness of the washers can be used to regulate the rigidity of the swing movement.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for the universally pivotal mounting of cylindrical components with axial forces to be absorbed, with the possibility of easy axial adjustment of the components.

Known bearings for all-round swing / spherical / bearings of mostly cylindrical components with axial forces are usually solved in a relatively complex way using the principles known from tilting bearings or parts with outer and inner spherical parts using tightening rings with large diameter union nuts. the devices do not usually permit the axial adjustment of the cylindrical component itself in a simple manner.

The above-mentioned drawbacks are eliminated by the universally swinging bearing according to the invention, whose essence is that a part of a generally circular cross-section is gripped by a system of three rings, two of which are specially grooved or pivoted. divided, connected by conventional clamping screws, are slidably threaded onto the component and engage with the outer conical surfaces in the conical recesses of the third ring provided on the outside diameter with a portion of the spherical surface which abuts the inner spherical surface of two flanges releasably connected to the fixed part.

An advantage of the solution according to the invention is that the part to be swiveled can be axially adjusted or adjusted by pulling the two rings against each other without further axial locking, whereby considerable axial forces can be absorbed, for example when mounting linear hydraulic motors.

An exemplary embodiment of a pivot bearing of a cylindrical member is shown in the drawing, wherein Fig. 1 shows a partial cross-section of a cylindrical member retained in a pivot bearing, and Fig. 2 shows a partial view of a specially grooved ring with a conical outer surface.

The pivot bearing according to the invention consists of grooved rings 1, 2 with a conical surface, pulled against each other by screws 3 in the conical recesses of the ring 4 with an outer diameter formed as part of a spherical surface coinciding with the inner spherical surface of two flanges 5 with washers 6 on the mounting screws 7 ·

The function of the swivel bearing described is as follows: the rings 1/2 are slidable over the workpiece to be clamped. By pulling the grooved rings 1, 4 by screws 3 against each other due to the conical surfaces of the ring 4, the rings 1, 2 are radially pressed against the cylindrical part and by friction they secure them against axial displacement.

The ring, with its outer spherical surface, fits into a portion of the spherical faces of the flanges 5, which are fastened by screws T to a fixed part of the structure, the stiffness of the shafts 6 controlling the stiffness of the rocking movement.
