Problems solved by technology

[0003] At present, most of the relevant designs are determined by the designer's experience, which does not guarantee that it is an optimal design. Some companies also have their own methods for measuring the flow rate of lubricating oil holes, but they are all for internal use of the company and have not been used. Promoted in the industry, so a fast and accurate method for measuring the flow rate of each lubricating oil hole was found. Through actual measurement, the obtained data can intuitively and quantitatively provide a basis for design

Embodiment 1

[0021] Embodiment 1: The test method is as follows: first, a small hydraulic loading pump station with a multi-stage decompression circuit is needed to act as a quantitative pump to provide lubricating oil with fixed parameters for the test, and the oil outlet of the pump station is connected with a pressure sensor and a flow sensor. By adjusting the overflow valve knob to change the flow rate and pressure of the oil outlet of the pump station to the value required by the test, the pump station is ready for use; secondly, the shaft to be tested is separated from each oil outlet with a rubber sealing ring, and placed in a transparent In the plastic shaft shell, each oil outlet is connected with a hose, and the pipeline is connected according to the system schematic diagram. According to the design, each lubrication hole is named and marked separately. The oil outlet of each hose can be freely placed in the oil tank or large capacity measuring cup.

Abstract

The invention discloses a method and a tool special for testing the static lubricating flow distribution of a fixed-shaft gearbox shaft and belongs to lubricating flow test devices. An oil pump of the tool is connected with an input end of a transparent plastic shaft shell through an overflowing valve and a flow meter; the oil pump is connected with the input end of the transparent plastic shaft shell in series through an oil inlet flexible pipe via the overflowing valve and the flow meter; an output end of the transparent plastic shaft shell is connected with an oil pool through an oil outlet flexible pipe; an oil-proof rubber sealing ring is connected to the interior of the transparent plastic shaft shell; and the transparent plastic shaft shell is connected to a base bracket. The invention has the advantages that: the tool is simple in structure, low in cost of replacement of the rubber sealing ring and convenient to process; the flow of an oil outlet can be directly obtained by measuring volume; during the testing of the lubricating flow distribution of shafts with different shaft diameters, the rubber sealing ring with a proper size is required to be selected, and a pipeline is connected, so the flow distribution of the oil outlet of lubrication oil can be conveniently measured; and the tool is convenient, quick, low in test cost, short in test period and convenient for experiment operation.

Description

technical field [0001] The invention relates to a test method and tooling for static lubricating flow distribution, in particular to a test method and special tooling for static lubricating flow distribution of a shaft of a fixed-axis gearbox. Background technique [0002] For the lubrication of the parts on each shaft in the fixed-axis gearbox, the lubricating oil is distributed through the axial drilling and radial hole connection on the shaft. The lubricating oil is provided by the variable speed pump in the box. The lubricating oil flow required by different lubricating points is different. The determination of the size of each lubricating oil hole in the design process is very important to the distribution of lubricating oil flow. After theoretically calculating the required flow of each lubricating point, the lubricating oil flow of each lubricating point is adjusted by adjusting the size of the lubricating oil hole. Then determine the size of each lubricating hole; ho...
