1、 ANSI/ASABE AD5674:2004 SEP2015 Tractors and machinery for agricultural and forestry Guards for power take-off (PTO) drive shafts Strength and wear tests and acceptance criteria American Society of Agricultural and Biological Engineers ASABE is a professional and technical organization, of members w

2、orldwide, who are dedicated to advancement of engineering applicable to agricultural, food, and biological systems. ASABE Standards are consensus documents developed and adopted by the American Society of Agricultural and Biological Engineers to meet standardization needs within the scope of the Soc

3、iety; principally agricultural field equipment, farmstead equipment, structures, soil and water resource management, turf and landscape equipment, forest engineering, food and process engineering, electric power applications, plant and animal environment, and waste management. NOTE: ASABE Standards,

4、 Engineering Practices, and Data are informational and advisory only. Their use by anyone engaged in industry or trade is entirely voluntary. The ASABE assumes no responsibility for results attributable to the application of ASABE Standards, Engineering Practices, and Data. Conformity does not ensur

5、e compliance with applicable ordinances, laws and regulations. Prospective users are responsible for protecting themselves against liability for infringement of patents. ASABE Standards, Engineering Practices, and Data initially approved prior to the society name change in July of 2005 are designate

6、d as “ASAE“, regardless of the revision approval date. Newly developed Standards, Engineering Practices and Data approved after July of 2005 are designated as “ASABE“. Standards designated as “ANSI“ are American National Standards as are all ISO adoptions published by ASABE. Adoption as an American

7、National Standard requires verification by ANSI that the requirements for due process, consensus, and other criteria for approval have been met by ASABE. Consensus is established when, in the judgment of the ANSI Board of Standards Review, substantial agreement has been reached by directly and mater

8、ially affected interests. Substantial agreement means much more than a simple majority, but not necessarily unanimity. Consensus requires that all views and objections be considered, and that a concerted effort be made toward their resolution. CAUTION NOTICE: ASABE and ANSI standards may be revised

9、or withdrawn at any time. Additionally, procedures of ASABE require that action be taken periodically to reaffirm, revise, or withdraw each standard.

34、 ambient temperature any temperature between 5 C and 35 C 4 General test conditions 4.1 Guard 4.1.1 The guard shall be representative of a production model and be within the tolerances specified for the guard. The results obtained from the sample can be used to certify guards of shorter or longer le

35、ngths, provided the basic design remains the same. When a guard is designed for use with several drive-shaft types, a representative selection of shaft and guard combinations shall be tested. 4.1.2 If the guard is made of plastic material (or any other material susceptible to degradation by UV radia

36、tion), it shall be certified by the manufacturer to be resistant to degradation from UV radiation under an appropriate, recognized method. See Annex B for an example. 4.1.3 During testing, all operating and maintenance instructions specified for the shaft and guard shall be complied with, except whe

37、re specifically mentioned by this International Standard. 4.1.4 The guard shall be tested in conjunction with a PTO drive-shaft of between 900 mm and 1 010 mm closed length for which it is intended. The same guard shall be used throughout all the tests. 4.2 Other 4.2.1 Where specified in this Intern

38、ational Standard that the PTO drive-shaft shall be revolving, its rotational frequency shall be 1 000 r/min. 4.2.2 All tests shall be carried out in accordance with the schedule and in the sequence given in Annex A. 5 Test equipment 5.1 General 5.1.1 Wear test equipment, which shall be capable of ho

39、lding the PTO drive-shaft and revolving it at a frequency of 1 000 r/min. The shafts and guards shall be mounted as specified for operational use and only fixed by their designated restraining device. The fixing points shall be in accordance with ISO 500 ANSI/ASABE AD500-1 and the equivalent machine

40、 standard unless otherwise specified for that type of shaft. The size and shape of the wear test equipment shall be such that an even test environment is maintained, e.g. heat and the dust specified in 5.2.3. 5.1.2 Strength test equipment, which shall allow the accurate application of known loads at

41、 controlled temperatures and at the required frequency of rotation within the tolerances stipulated in Table 1.

43、uires the use of water, it shall be potable (i.e. drinking water). 5.2.2.2 When a test requires a saltwater solution, it shall be prepared by dissolving sodium chloride in water to produce a concentration of 50 g/l 5 g/l. The sodium chloride shall be white and shall give a colourless solution in wat

44、er. It shall be substantially free from copper and nickel, and shall not contain more than 0,1 % of sodium iodine and not more than 0,4 % of total impurities calculated for dry salt. 5.2.3 Test dust 5.2.3.1 The test dust shall consist of a mixture composed of equal parts, by mass, of organic and min

45、eral dust. 5.2.3.2 The organic dust shall be ground lucerne with a maximum percentage of 12 % water and with a maximum particle size of 2 mm. An environment of 0.5 kg/m3shall be maintained. 5.2.3.3 The mineral dust shall be a simple phosphated fertilizer, and shall contain as principal elements sili

46、cophosphates of calcium having the following characteristics: minimum content: 9 % of P2O5 total (3 %); other: at least 75 % of the P2O5 total declared, soluble in a 2 % concentration of citric acid.

48、chment of components which could contribute to the deterioration of the guard. For the test sequence, see Annex A. The PTO drive-shaft guard is deemed to have passed the test if the guard has no holes or deformation which leave the shaft unprotected, and the guard has no breakage, crack or part sepa

49、ration. 6.2 Wear test 6.2.1 For the whole test, the shaft shall be revolving and, whilst revolving, shall be repeatedly extended to its extended length (see ISO 5673-1 ANSI/ASABE AD5673-1), held for 1 min, then returned and held at its closed length (see ISO 5673-1 ANSI/ASABE AD5673-1) for 4 min. This shall be repeated for the duration of the test period. See Annex A for the test sequence. Guards shall only be fixed using the normal fixing and restraining s
