Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0013] Such as figure 1 As shown, the multifunctional gear rotor bearing system test device is composed of transmission shaft 1, mass disc 2 (or gear), sliding bearing 6 (or rolling bearing) and bearing housing 3 (or frame, box). Above, through the expansion sleeve connection, install the mass disc or the gear 2, and install and support the sliding bearing or the rolling bearing 6 in the bearing seat 3 at both ends of the transmission shaft 1, to form various single-span rotor-bearing subsystems.

[0014] Such as figure 2 As shown, more than two single-span rotor-bearing subsystems are connected in series through various couplings 4 to form a multi-span rotor-bearing system. It can be used to study the dynamic characteristics of steam turbines and water turbines, such as stability, critical speed, rotor misalignment, mass imbalance, the influence of ...

Abstract

The invention discloses a multi-functional gear rotor bearing system test apparatus which comprises a rotating shaft, a quality disk or gear, a bearing, a bearing seat or frame. It is fixed-connected with the quality disk or the gear by the cover on the rotating shaft; the support bearing is positioned inside the bearing seats on the two sides of the rotating shaft to form single rotor-bearing subsystem; at least two single rotor-bearing subsystems are connected with each other by coupling; at least two single rotor-bearing subsystems are levelly arranged with the same gear location of each single rotor-bearing subsystem; the gears intermeshed with each other to form a gear intermeshing parallel rotor-bearing system; at least three single rotor-bearing subsystem are levelly arranged, wherein two gears with different gear number are fixed on one of the three levelly arranged, which are intermeshed with the other two gears of the adjacent single rotor-bearing subsystems to form speed reducer or speed acceleration.

Description

technical field [0001] The invention relates to a rotor system test device, in particular to a device for the dynamic performance test of the rotor in the three major power systems of a steam turbine, a water turbine and a large centrifugal compressor, and a device for the dynamic performance test in a gear transmission system. Background technique [0002] At present, in the three major power systems of steam turbine, water turbine and large centrifugal compressor, and in the high-speed precision gear transmission, there is a rotor-sliding bearing system, and its dynamic characteristics have a decisive impact on the operating state and stability of the unit. ; In a centrifugal compressor, two or three rotor-sliding bearing subsystems are linked together through gear meshing to form a new dynamic system. Because the first three types of systems belong to large-scale power equipment, even a small failure will cause great economic losses during operation, ...
