Axis runout trajectory test device

Abstract

The invention provides an axis runout trajectory testing device for a combined harvester threshing drum. The device comprises a magnetic outer casing, a magnetic hanging brush, a coordinate card and ashaft end adsorption mechanism, which are coaxially mounted; one end of the magnetic outer casing is connected with one end of the shaft end adsorption mechanism; one side of the coordinate card is mounted on one end of the shaft end adsorption mechanism; the magnetic suspension brush is suspended and fixed inside the magnetic outer casing; a tip of one end of the magnetic suspension brush abutsthe other side of the coordinate card; the magnetic suspension brush is positioned in suspension, and the other parts rotate together with the axis; the brush records a trajectory which is an upside down and left-and-right mirroring version of the actual axis runout trajectory on the grid coordinate card; and finally the grid coordinate card is inserted into a card reader to obtain an amplified erect axis runout trajectory. The device can be applied to test the runout state of the threshing drum of various rice combine harvesters, and can solve the problem that the existing threshing drum axisrunout test device is susceptible to friction damage by the threshing drum shaft.

Description

technical field [0001] The invention belongs to the technical field of assembly and balance detection of a threshing cylinder of a combine harvester, and in particular relates to a beating track testing device for a threshing cylinder axis of a combine harvester. Background technique [0002] During the threshing process of the combine harvester threshing drum, due to the impact and entanglement of the material, or because of the imbalance of the threshing drum itself, the shaft center is constantly beating, which affects the reliability and threshing performance of the threshing drum itself, and it is easy to make the equipment malfunction. The first step to solve the problem is to detect the beating track of the axis center during the working process of the threshing cylinder and to find the cause of the fault. It can be seen that the detection of the beating track of the axis center is very important. [0003] At present, the devices and methods for measuring the beating...

Problems solved by technology

The invention is applicable to the measurement of the beating track of the axis center of various rotating shafts. When it is used for the test of the beating track of the axis center of the threshing drum of a combine harvester, it not only solves the problem that the existing device is easy to rub and collide with the threshing drum shaft, thus causing the device to be damaged. , and the structure is simple, low in price, easy to install and disassemble, and can effectively test the beating track of the axis of the threshing drum. Phenomenon that causes the axis to constantly beat
