1、 ANSI/ASABE AD5673-1:2005 SEP2017 Agricultural tractors and machinery Power take-off drive shafts and power-input connection Part 1: General manufacturing and safety requirements American Society of Agricultural and Biological Engineers ASABE is a professional and technical organization, of members

2、worldwide, 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 So

3、ciety; 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 ensu

5、re 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 designat

6、ed 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 mate

8、rially 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9、 or withdrawn at any time.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.

33、l joints, the bearings between the shaft and guard and the telescopic members are provided with lubricating nipples, these shall be easily lubricated, e.g. by direct access to all the nipples, or by moving parts of the guard, provided that clear instructions are given by the manufacturer specifying

34、that the guard shall be opened only by means of a tool and the resetting of the guard is possible without the use of the tool. 4.6.2 Lubrication holes Where the lubricating operations require holes to be present in the drive shaft guard, the greatest dimension shall be 30 mm. 5 Safety requirements 5

35、.1 General requirements The PTO drive shaft guards shall be designed to prevent contact with the moving components of the PTO drive shaft, with the PTO drive shaft being operated in accordance with the instruction handbook. No device (e.g. adapters) shall be installed between the tractor PTO and the

36、 primary PTO drive shaft. If there is an accessory, e.g. a torque limiter and/or an overrun device, on the primary PTO drive shaft, it shall be positioned only on the PIC side of the primary PTO drive shaft (see Figures 3 and 4). A marking on the primary PTO drive shaft guard shall indicate the end

37、of the primary PTO drive shaft that is to be fitted to the tractor or self-propelled machine (see Figure 12). ANSI/ASABE AD5673-1:2005 SEP2017 Copyright American Society of Agricultural and Biological Engineers 3 Where allowed by regional or national legislation, an accessory such as a torque limite

38、r and/or an overrun device may be positioned on the tractor PTO side of the primary PTO drive shaft. If there is an accessory, e.g., a torque limiter and/or an overrun device, on the primary PTO drive shaft, it can be positioned either on the PIC side of the primary PTO drive shaft (see Figures 3 an

39、d 4) or on the tractor or self-propelled machine PTO side, provided that the guarding overlaps are no less than those specified in sections 5.2 and 5.3. A marking on the primary PTO drive shaft guard shall indicate the end of the primary PTO drive shaft that is to be fitted to the tractor or self-pr

40、opelled machine (see Figure 12). On secondary PTO drive shafts, an accessory such as a torque limiter and/or an overrun device may be positioned on both ends of the shafts. No marking is required. Information for the use of fixing points (e.g. a 16 mm diameter hole) shall be provided in the instruct

41、ion handbook for the restraining system (see Figure 5). If regional or national legislation allows rotating PTO drive shaft guards, then a restraining system is not needed. The implement shall be supplied with a support for the primary PTO drive shaft for keeping it in the storage position when unco

42、upled from the tractor PTO. This support shall not be the device restraining system used to prevent the rotation of the primary PTO drive shaft guard. Information for the use of the support shall be given in the instruction handbook. In the instruction handbook (see 6.1), the manufacturer shall prov

43、ide recommendations for proper application and any information limiting the use of the PTO drive shaft and its guards, including operating data and warnings against misuse. Information about requirements of the support (e.g. form, type, position etc.) for the PTO drive shaft and, if present, the res

44、training system, shall also be provided. A sign illustrating the need to read the instruction handbook shall be provided on the PTO drive shaft guard (see 6.2). A sign shall be provided at a prominent location on the PTO-powered implement, near its PIC, specifying the nominal operating speed and the

45、 direction of rotation of the PTO drive shaft. Information on how to modify the PTO drive shaft length shall be included in the instruction handbook. 5.2 Overlap between tractor master shield and primary PTO drive shaft guard 5.2.1 Universal joint The primary PTO drive shaft guard cone shall cover t

46、he drive shaft at least up to the end of the inner yoke of the universal joint in order to ensure sufficient overlap between tractor master shield and primary PTO drive shaft guard (Figure 1, Item 11). See Table 2 for the value of dimension c as shown in Figure 6. The dimension, c, shall be measured

47、 in straight line position of the primary PTO draft drive shaft.
