1、 ANSI/ASAE S331.6 AUG2015 Implement Power Take-Off Drive Shaft Specifications American Society of Agricultural and Biological Engineers ASABE is a professional and technical organization, of members worldwide, who are dedicated to advancement of engineering applicable to agricultural, food, and biol
2、ogical 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 Society; principally agricultural field equipment, farmstead equipment, structures, soil and water reso
3、urce management, turf and landscape equipment, forest engineering, food and process engineering, electric power applications, plant and animal environment, and waste management. NOTE: ASABE Standards, Engineering Practices, and Data are informational and advisory only. Their use by anyone engaged in
4、 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 ensure compliance with applicable ordinances, laws and regulations. Prospective users are responsible for
5、 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 designated as “ASAE“, regardless of the revision approval date. Newly developed Standards, Engineering Practi
6、ces 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 National Standard requires verification by ANSI that the requirements for due process, consensus, an
7、d 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 materially affected interests. Substantial agreement means much more than a simple majority, but not nece
8、ssarily 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 CAUTION NOTICE: ASABE and ANSI standards may be revised or withdrawn at any time. Additionally, procedures of ASABE require that action be taken periodicall
9、y to reaffirm, revise, or withdraw each standard. Copyright American Society of Agricultural and Biological Engineers. All rights reserved.

13、 January 2010; reaffirmed by ANSI February 2010; revised and approved by ASABE and ANSI August 2015. Keywords: Drive shaft, Implement, Power take-off 1 Purpose 1.1 The purpose of this Standard is to establish multiple categories of universal joint drive shafts with two subsets of telescoping members
14、 each, one heavy duty, HD, and one regular duty, RD 1.2 The intended use of the drive shafts is between tractor power take-off (PTO) shafts and power input connections (PIC), or any universal joint application within the implement. The PTO drive shaft from the tractor PTO to the (PIC) is considered
15、a part of the implement. 1.3 This Standard does not provide for dimensional interchangeability from one implement to another. 2 Normative References The following referenced documents are indispensable for the application of this document.

19、Drive shafts shall meet the requirements of the static and dynamic tests. Separate assemblies shall be used for each test. 4.2 Static torsional tests 4.2.1 Torsional yield test for cross and bearing kit and yokes. With zero angularity, cross, bearings, and yokes shall withstand the static torque sho

Failure is defined as a break, crack or permanent deformation greater than a 50% change in the slope of the torque deflection curve. 4.2.2 Torsional yield test for connecting members. Telescoping members between universal joints shall withstand the static torque shown
21、in Table 1 without failure. Failure is defined as any break, crack or permanent deformation exceeding 1 degree per 305 mm of length (1 degree per lineal foot). This does not apply to torque limiters used between joint centers. Table 1 Static torsional requirements Category Cross, Bearing, and Yoke A

(This test may be run at any of the three listed speeds.) Note 1: Due to the 10 degree joint angle, the bearing cap will oscillate a total of 40 degree
26、s relative to the cross during a complete revolution of the drive shaft. ANSI/ASAE S331.6 AUG2015 Copyright American Society of Agricultural and Biological Engineers 3 An L10 life level, as defined in ANSI/ABMA 11-2014, shall be used for crosses and bearings. Failure of a cross and bearing kit will
27、be determined by the temperature of the needle cups. A temperature in excess of 178 C (350 F) is a failure. This test may be run without stopping, or in segments of 8 h. Joints may be regreased during the test at 8 h intervals or per the manufacturers recommendations. Table 2 Dynamic torsional requi
