PHILIPPINE AGRICULTURAL ENGINEERING STANDARD PAES 304: 2000 Foreword The development of this National Standard was initiated by the Agricultural Machinery Testing and Evaluation Center (AMTEC) under the project entitled "Enhancing the Implementation of the AFMA Through Improved Agricultural Engineering Standards" which was funded by the Bureau of Agricultural Research (BAR) of the Department of Agriculture (DA). This Standard was reviewed by the Technical Committee for Study 2 – Development of Standards for Engineering Materials and was circulated to various private and government agencies/organizations concerned for their comments and reactions. These standards were presented to the Philippine Society of Agricultural Engineers (PSAE) and subjected to a public hearing organized by the National Agriculture and Fisheries Council (NAFC). The comments and reactions received during the presentation and public hearing were taken into consideration in the finalization of the standards. This Standard has been technically formulated in accordance with PNS 01:Part 4:1998 – Rules for the Structure and Drafting of Philippine National Standard. It provides specifications of keys and its corresponding keyways and does not cover manufacturing specifications. This standard was based from JIS B 1301:1996, Keys and their corresponding keyways. In the preparation of this standard, the following references were considered. Faires, V. M. 1969. Design of Machine Elements. Macmillan Company, New York USA.

The designation of dimensions of parallel keys and parallel keyways are shown in Figure 1 and 2 respectively and are defined as follows: b – the cross-sectional width of the key t1 – height of keyway for the shaft h – the cross-sectional height of the key t2 – height of keyway for the hub l – length of the key d – shaft diameter b1 – width of keyway for the shaft r – radius of curvature b2 – width of keyway for the hub  PAES 304:2000 b b l h Figure 1 – Designation of dimension of parallel keys Section of keyway r2 t2 h b2 t1 d b1 r1 Figure 2 - Designation of dimension of keyway for parallel key 2  PAES 304:2000 5.2 Classification of key ends The end of the parallel key shall be classified into three classes as shown in Figure 3 according to its shape.

Series 2: Adequate for the case where the positioning is made by key and the torque is not transmitted by it, e.g., where the shaft and the hub are in the fit of “interference fit”. 2. Series 3 corresponds to the shearing strength at the shearing cross-section area shown in the Table. This shearing cross-section area is the calculated value of the part to be sheared at the time when the key is sinking completely in the keyway. 11  PAES 304:2000 8 Materials The key shall be free from cracks and harmful flaws, burrs and rust in appearance.

This Standard was reviewed by the Technical Committee for Study 2 – Development of Standards for Engineering Materials and was circulated to various private and government agencies/organizations concerned for their comments and reactions. These standards were presented to the Philippine Society of Agricultural Engineers (PSAE) and subjected to a public hearing organized by the National Agriculture and Fisheries Council (NAFC). The comments and reactions received during the presentation and public hearing were taken into consideration in the finalization of the standards. This Standard has technically formulated in accordance with PNS 01:Part 4:1998 – Rules for the Structure and Drafting of Philippine National Standard. It provides specifications and proper application of shafts for agricultural machines and does not cover manufacturing specifications. In the preparation of this standard, the following references were considered. Baumeister, Theodore (ed.) 1997. Mark’s handbook for mechanical engineers. 10th Edition. Mc Graw Hill Book Company, USA.

It provides the axis of rotation, or oscillation, of elements such as gears, pulleys, flywheels, cranks, sprockets, and the like and controls the geometry of their motion. 4 Materials Standard shafts for agricultural machines are usually of steel designation 1020 (cold rolled). For special purposes, stainless steel shafts usually of steel designation 304 or 316 shall be used. 5 Power rating Power ratings of shafts are presented in Tables 2-7. These tables can be used to find the approximate shaft diameter for various service conditions. Standard keyseated shafting, using a safe shear stress of approximately 41.369 MPa is the basis of Tables 2-4. For special application requiring the use of stainless steel shafts, power ratings are computed by multiplying a safe shear stress factor (Table 1) in order to arrive at a correct power rating. For safe shear stress of other materials, use 1/10 of the nominal ultimate tensile strength.
