Problems solved by technology

However, most of the existing mechanical fault simulation test benches are not comprehensive enough and can only simulate one or two types of equipment faults.
Some are too close to the actual equipment, that is, as a test bench, its appearance is bulky and the operation is complicated

Embodiment Construction

[0018] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

[0019] Such as figure 1 The shown special base of a mechanical transmission system failure simulation comprehensive test bench is composed of a first guide slot 1 , a second guide slot 2 , a power distribution slot 3 and a foot 4 . The first guide groove 1 is used for installing the motor, shaft coupling, shaft, bearing housing, counterweight plate and pinion. The second guide groove 2 is used to install the bull gear, the bearing seat, the shaft coupling and the brake. The power distribution slot 3 is used for installing motor controllers, brake controllers, and data cable adapters. A counterbore 12 is respectively designed on the legs 4 for fixing the base and the foundation by bolts, and the counterbore can make the test bench beautiful and simple after complete assembly. The bottom of the base is a sun-shaped bottom surface 11 . A boss 9 is d...

Abstract

The invention discloses a dedicated base of a fault simulation comprehensive experiment table for a machine driven system, which comprises a first guide slot (1), a second guide slot (2), a power distribution groove (3) and a supporting foot (4). Three lines of uniformly distributed screwed holes (5) are designed on a top surface of the base for installing parts flexibly; and a bottom surface of the base is designed to the shape of a Chinese character 'ri', which reduces the contact area between the base and the foundation, thus reducing the processing cost and difficulty obviously. A boss (9) is arranged above a common wall of the first guide slot (1) and the second guide slot (2) for positioning accurately in radial direction when a bearing seat is installed. The guide slot (1) is provided with a groove (6) for installing an alternating-current motor; a groove (7) is used for holding a gear pair, and a through hole (8) is used for wiring data lines of a sensor. The design of the base satisfies the overall design and performance requirements of the experiment table and achieves the aims of flexible and convenient installation and replacement and economical and feasible manufacturing.

Description

technical field [0001] The invention belongs to the field of vibration monitoring and diagnosis of a mechanical transmission system, and relates to a special base for comprehensively, conveniently and reliably simulating some typical faults of bearings and gears and a comprehensive test bench for unbalanced faults of rotors. Background technique [0002] Gear failures, bearing failures and rotor imbalances are the most common types of failures in mechanical transmission systems. In engineering practice, major accidents caused by these three types of failures in electromechanical equipment have occurred frequently. Carrying out condition monitoring and fault diagnosis for such equipment has become an urgent need for large enterprises, and will certainly bring huge economic and social benefits. For the teachers and students in school, it is necessary to contact and understand the equipment and conditions in the actual engineering, but because the environment and working condi...
