Axis trace simulation test bench

Abstract

The object of the invention is to provide an axis trace simulation test bench comprising a sealed box body, a speed regulating motor, a connecting rod, a support seat A and a support seat B, wherein abase mounting beam is installed below the sealed box body, a leveling foot is installed below the base mounting beam, the support seat A is fixed in the sealed box body through a base A, the supportseat B is fixed in the sealed box body through a base B, transmission shafts are respectively mounted on the support seat A and the support seat B through a bearing A and a bearing B, the speed regulating motor is installed outside the sealed box body and connected to the transmission shafts through transmissions, the middle parts of the transmission shafts are connected to the connecting rod through a rotating pair, the lower end of the connecting rod is connected to a fork by a pin shaft, an adjusting seat is arranged under the fork, a spring is provided between the adjusting seat and the fork, the upper end of the spring is connected with an adjusting nut, and the adjusting nut is screwed on the adjusting screw at the lower end of the fork. The axis trace simulation test bench is widelyapplicable to the debugging measurement of the shaft and rail system of large mechanical equipment.

Description

technical field [0001] The invention relates to a diesel engine test device, in particular to a diesel engine connecting rod journal axis track test device. Background technique [0002] The bearing bush is one of the key components of high-power mechanical equipment, and it has a wide range of applications. The bearing bush has many defects or deficiencies in structural design, product processing, parts installation and debugging, maintenance and testing, etc., which will make the equipment run. Vibration, local oil film pressure increase, friction force increase, and lubricating oil flashing intense flashing impact pressure can easily cause fatigue pitting and peeling of the alloy layer of the bearing pad, and even cause major accidents. Shaft track detection technology is the most commonly used fault diagnosis technology for bearing pads. Through the tested shaft center track data, basic information such as oil film thickness and oil film pressure distribution of transmis...

AI Technical Summary

Problems solved by technology

[0003] At present, the method for debugging the axis trajectory is mainly to install the axis trajectory testing equipment on the principle prototype after the completion of the principle prototype, and then to debug and write the program on site. This not only makes the project seriously lagging behind, but also cannot collect Standard Test Information

In addition, there are some laboratory-based axis track test platforms on the market, but most of the test systems are dedicated systems. These systems can only simulate the operating characteristics and speed of a specific transmission structure, and cannot be used for general-purpose systems on the market. Common test bench machines available for most rotating machinery
