Problems solved by technology

This has the effect that the shaft and the inner ring expand more strongly than the outer ring, as a result of which the compression and bias in the turret bearing, in particular in the radial tracks, increase, which leads to a reduced service life

Embodiment Construction

[0023] figure 1 Shown is a part of a turntable machine 1 according to the invention, which comprises a stand 2 with a support member 3 which is a fitting member with an outer bearing for the turntable bearing. The clamping section of the ring, which is described below.

[0024] Furthermore, a shaft 4 is provided, which has a further mounting component with a clamping section for the inner ring of the turntable bearing, wherein the clamping section is via the hollow cylindrical shape of the shaft 4 Section 5 of is implemented. The shaft 4 has a platform flange 6 , on which, in a manner not shown, its own turntable is accommodated.

[0025] A torque motor 7 is provided for driving the shaft 4, said torque motor comprising: a stator 8, fixed on the frame side; and a rotor 9, separated via an air gap, arranged in a hollow cylindrical section of the shaft 4 In the extension of 5. The stator 8 and the rotor 9 are separated in a known manner via an air gap, so that the rotor 9 ca...

Abstract

The invention relates to a turntable bearing device, comprising: a turntable bearing (10), said turntable bearing having an inner ring (12), an outer ring (11) and rolling bearings arranged in one or more rows (13, 14, 15) bodies rolling on the inner and outer rings; and a fitting member (3, 4) each having clamping sections (16, 28), the inner ring (12) and the outer ring ( 11) Connection with the clamping section. According to the invention it is provided that the clamping section (16, 28) of at least one mounting component (3, 4) is formed radially elastically on the mounting component (3, 4) and / or the inner ring (12) and / or The outer ring (11) has a radially elastic connecting section (25), via which the respective ring (11, 12) is connected to the mounting component (3, 4).

Description

technical field [0001] The present invention relates to a turntable bearing device, which comprises: a turntable bearing, the turntable bearing has an inner ring, an outer ring and rolling bodies arranged in one or more rows, and the rolling bodies roll on the inner ring and the outer ring; and In each case a mounting part having a clamping section to which an inner ring and an outer ring are connected. Background technique [0002] In order to improve productivity, when machining workpieces, the integration of multiple processes is increased. One possibility is to combine turning or milling operations in one machine. The machine usually comprises a turntable which is mounted in rotation via a corresponding turntable bearing arrangement. Turntable bearing arrangements have hitherto been designed only for pivoting purposes or for slow, continuous rotation, but it is necessary to extend the working range that the bearing arrangement be designed such that it can also be opera...
