ABSTRACT:
A bearing arrangement in a tunable magnetron, in which a sleeve-shaped body (12) is journalled on a central column (10) by means of two bearings (14, 15). The distance between the inner rings (18, 19) and outer rings (22, 23) of the bearings is determined by distance means (20, 21) which generally can be sleeve-shaped. According to the invention, at least one distance means, suitably both distance means, is temperature compensated by being composed of an odd number of partial elements (30-32; 37-39). The elements all extend in the longitudinal direction of the distance means, and each distance means includes two end elements (30, 32; 37, 39) which bear against the respective bearing part (18, 19; 22, 23) and an intermediate element (31; 38). The elements in each distance means are in such force-transmitting connection with each other that, with temperature variations, two adjacent elements impart to the distance means length variations in opposite direction. The total length of all elements acting in one direction is so selected in relation to the total length of all elements acting in the opposite direction, and in relation to the linear expansion coefficients for the different elements, that a predetermined variation of the total length of the distance means with the temperature is obtained.
