Title: Gyroscope rotor shaft bearing without play - has common bush outer bearing surfaces for coaxial roller bearing rings
Inventor: ANDRES HELMUT
IPC: F16C25/06
Filed: 1980-05-12
Abstract: A play-free shaft bearing for a gyroscope rotor and the associated method of manufacture involves the use of two equiaxial roller bearing rings with adjustable axial compression. The arrangement contains a minimum of individual components and involves simple very accurate assembly. The outer bearing surfaces of the rings (30,31) are part of a common bush (32). One inner bearing surface (34) is part of the shaft (16,20) whilst the other is an inner bearing ring (36) fitted onto the shaft. The inner bearing ring is displaced only by a high axial force considerably in excess of the axial forces acting on the shaft bearing during operation. Displacement of the inner bearing ring only causes an elastic deformation of components. The bush may have cut-outs reducing axial stiffness.

Title: Hydraulic control device for a servomotor, in particular for tie-bar relief in an injection-moulding machine
Inventor: TITTMANN EGON DIPL ING
IPC: B29C45/68
Filed: 1981-02-04
Abstract: A hydraulic control device (10) having 2-way fitted valves (25, 26, 27) is proposed, which in the case of injection-moulding machines having mould halves (12, 13) actuated by means of toggle levers (15), avoids impact effects upon relief when the mould is opened. A fitted valve (26) lying in the relief branch (29, 37) is assigned a precontrolling pressure-limiting valve (61), the outlet side (59) of which can be pressurised via a directional valve (46) precontrolling the additional fitted valves (25, 27). The fitted valve (26) lying in the relief branch has fine-control bevels (83) on its shut-off member (81) and can be controlled additionally via a switching valve (72). Pressure-limiting valve (61) and assigned fitted valve (26) cooperate in a first stage during mould opening as a precontrolled pressure-limiting system for a gentle tie-bar relief, the counteracting force required for damping depending on the pressure value set at the pressure-limiting valve (61). In a second stage during mould opening, the time-dependently influenced switching valve (72) cooperates with the fitted valve (26) as a fully opening, normal directional valve. <IMAGE>

Patent DE-3108242-A1 (DE)
Title: Method for the calorific measurement of the power loss of a gear and a device for carrying out the method
Inventor: THIEL ERHARD DIPL ING
IPC: G01M13/02
Filed: 1981-03-05
Abstract: During the calorific measurement of the power loss of a gear, the gear is heat-insulated and the heat resulting from the power loss is preferably conducted away with the gearing oil with the aid of a heat sink, in particular of a heat exchanger (11). When the operating state of the gear (1) changes, the power loss which occurs and thus the amount of heat to be conveyed away also changes. The various measuring points can be quickly determined without long waiting times if, according to the invention, the temperature of the gear (1) is kept constant independently of the respective operating state. This is achieved preferably by determining the gear temperature, in particular by measuring the temperature in the oil sump by means of a heat sensor (32) which, in the event of a change in the operating state and in the associated tendency of the gear temperature to rise or fall, issues via a temperature controller (31) an appropriate instruction to a speed of revolution actuator (30) which itself acts on a drive motor (13) of the feed pump (12) in the circuit (1,7,11,8). The heat loss is determined via the amount of coolant flowing through the secondary side, with the aid of the flow meter (23) and of a temperature differential meter (34). In order to avoid heat being conducted away via the connection shafts (2 and 3) which are guided through towards the outside, these are preferably placed at the same temperature, which also constitutes the set value for the controller (31), with the aid of devices (38 and 39). <IMAGE>
