Mortar

摘要

A mortar includes at least one barrel mounted movably over a ball journal in a bottom supporting device, and an aiming device serving to aim the barrel vertically and horizontally. In order to be able to aim the barrel of the mortar automatically in a simple and cost advantageous manner, the aiming device preferably comprises a carriage that can be moved along guideways essentially horizontally towards or away from the barrel. At the carriage, the first end region of a pivoted arm is mounted so that it can be rotated about a pivot axis, and the second end region of the pivoted arm is connected with a spherical plain bearing, guiding the barrel. The spherical plain bearing embraces a housing part, which is open at its end faces and in which an inner part is mounted spherically (rotatably), which contains a cylindrical barrel guide, for movably accommodating the barrel.

1. A mortar comprising:
(a) a bottom supporting device; (b) at least one weapon barrel mounted to move via a ball-ended rod on the bottom supporting device; and (c) an aiming system operable to aim elevation and azimuth of the at least one weapon barrel, wherein the aiming system comprises i. a hinged bearing having a housing part, wherein the housing part has two open end faces and on an outside of the housing part a pivoting arm is mounted so that the pivoting arm is rotatable about a horizontal axis, and a rotatably mounted inner part is located in the pivoting arm, wherein the rotatably mounted inner part is connected to a cylindrical barrel guide for movable accommodation of the at least one weapon barrel, and the rotatably mounted inner part facilitates a de-coupled, axis-parallel installation of a system for determining geographical location to an interior component, wherein the rotatably mounted inner part comprises a bearing ball that is attached to the cylindrical barrel guide, wherein the bearing ball surrounds the cylindrical barrel guide and is at least partially accommodated by corresponding bearing shells that are connected to the housing part of the hinged bearing.
