Description
TECHNICAL FIELD
[0001] The application relates to a non-metal roller friction characteristic test device and a monitoring system for a rotary cylinder wind sail, and belongs to the field of ship energy-saving devices. BACKGROUND
[0002] The rotary cylinder wind sail is a wind-assisted propulsion device used in the field of ship energy saving, which relies on the Magnus aerodynamic effect to provide auxiliary power for ship propulsion, thereby achieving an average fuel saving of 5%-25%. The rotary cylinder wind sail is provided with upper and lower rotary supports, and the non-metal roller is a main component of the lower support of the outer rotor of the rotary cylinder. The non-metal roller is mainly composed of a roller, a roller support, a propulsion assembly, a guide assembly and a mandrel, and the non-metal coating on the surface of the roller mainly serves to reduce the noise of the operation of the outer rotor of the rotary cylinder. Meanwhile, the friction loss of the roller assembly will increase the power consumption of the whole machine of the outer rotor of the rotary cylinder, thereby affecting the energy-saving efficiency of the rotary cylinder wind sail. In addition, the roller assembly operates under high speed and high load, and the wear rate will be greatly increased. Proper selection of non-metal materials for the roller and proper application of pre-load to the roller assembly will affect the normal operation of the lower support of the rotary cylinder wind sail. The friction characteristic test of the roller assembly can effectively analyze the friction loss of the roller assembly, and has guiding significance for the selection of non-metal materials on the surface of the roller. In addition, the test of the wear rate of the non-metal material can be carried out, and the reliability test of the roller can be carried out to evaluate the application reliability of the roller under real working conditions.
[0003] In summary, the non-metal roller friction characteristic test device of the rotary cylinder wind sail needs to have two functions:
[0004] 1. The rotation speed of the tested roller assembly is the same as that under real working conditions;
[0005] 2. The tested roller assembly is loaded according to the real running conditions on the test assembly, including the pre-load between the roller assembly and the outer rotor of the rotary cylinder.
[0006] For the friction characteristic test of the roller, the roller pair is usually used to test the friction characteristics of the guide wheel. However, the traditional friction characteristic test device has many shortcomings when directly applied to the non-metal roller of the rotary cylinder wind sail.
[0007] 1. The traditional roller pair friction characteristic test device is limited by the structure of the device and the selection of the motor, and can usually only carry out friction characteristic tests under low rotation speed and high load or high rotation speed and low load, and cannot carry out tests under high rotation speed and high load, which is the real running condition of the non-metal roller of the rotary cylinder wind sail.
[0008] 2. The traditional roller pair friction characteristic test device usually takes the non-metal roller as an isolated research object, and ignores the possible influence of the propulsion assembly and the guide assembly of the non-metal roller on the operation of the non-metal roller.
[0009] 3. Traditional friction characteristics testing equipment can only perform simple loading tests and cannot carry out preload tests for roller assembly installation;
[0010] 4. Traditional friction characteristic testing equipment can only carry out single friction characteristic testing, and it is difficult to simulate actual working conditions to apply mechanical load tests such as impact and vibration to the roller. Summary of the Invention

[0042] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.
[0043] The embodiments of the present application disclose a non-metal roller friction characteristic test equipment and monitoring system for a rotary cylinder sail, which as a whole comprises a subject roller assembly 101, a rotational speed loading device 102, a test equipment frame 103 and a load loading device 104, can carry out high-speed and high-load friction tests, carries out pre-load tests, impact, vibration and other dynamic tests of the subject roller assembly 101 during the working process, and realizes all-around friction and wear tests.
[0044] The test equipment frame 103 is a basic support structure of the whole test equipment, adopts a solid frame design, provides a stable mounting platform for each device component, ensures the stability and reliability of the whole test system during the loading process, and is also a carrier for connecting the test roller assembly, provides a mounting interface for the guide assembly 106 in the load loading device 104, and realizes effective loading and transmission of the load.
[0045] The test roller assembly 101 is consistent with the structure of the roller assembly of the real spinning cylinder wind sail, and is fixed on the test equipment frame 103. The test roller is the core component of the assembly, which is made of non-metallic material, and is used to carry out friction characteristic test research. According to different test requirements, different material roller bodies can be replaced efficiently and conveniently according to the process of replacing the roller of the real roller assembly, so as to study the friction and wear performance of the roller in the application of the spinning cylinder wind sail. The roller guide assembly 105 is installed on the test roller assembly 101, and has the same structure as the guide assembly 106, which guides and limits the movement track of the roller, ensures the stable rolling of the roller in the predetermined direction during the test process, avoids the deviation or jamming of the roller under the action of load and vibration, and ensures the accuracy of the test data.

The guide assembly 106 is connected with the test equipment frame 103, so that the rotating speed loading device 102 does not deviate during the loading process, and has the same structure as the roller guide assembly 105, so as to ensure the movement coordination and consistency of each moving part in the whole test system. The loading frame 109 is used to support and connect each component, and can be manufactured by splicing or welding a frame, so as to provide a stable mounting base for each part. The four frame rollers 110 are installed at the bottom of the loading frame 109, which can reduce the friction between the rotating speed loading device 102 and the test table under the action of the load loading device 104, so that the force of the load loading device 104 can act more accurately on the friction contact pair of the metal roller 107 and the test roller assembly 101.
