Another important thing to consider is minimum hub thickness, which is calculated based on such factors as locking device outer diameter and surface pressure. The hub should be thicker than this value to prevent excess stress and early failure. Locking device manufacturers typically provide this formula.Andrew/Whittet-Higgins: Consider all costs of the assembly rather than the individual costs of each component.Keith/U.S. Tsubaki: Go keyless. Keys and splines weaken the shaft by cutting into it, requiring a larger shaft and accompanying parts, such as bearings, to handle the higher forces.End-user adviceWhat should END USERS do to maximize life and productivity?Carl/Ringfeder: Pay close attention to the OEM''s service instructions and use the locking device manufacturer''s walkerturnerdrillpressparts technical information to help with replacement or reinstallation. Warren/Fenner: In walkerturnerdrillpressparts general, locking devices don''t require any maintenance or special attention to maintain their performance and maximum life. The introduction of stricter exhaust and noise emission standards along with the related increase in sophistication of equipment, both mobile and stationary, has created many challenges and opportunities for OEM equipment, engine and component manufacturers. And one component that has gained importance in all of this has been engine exhaust insulation walkerturnerdrillpressparts blankets.Firwin Corp., a North York, Ontario, Canada, company is a manufacturer of custom removable insulation blankets for engine exhaust systems, as well as other walkerturnerdrillpressparts heat shield insulation products. These products are used in a variety of applications, including standby and prime power generation, marine, on-highway, mining, construction, forestry, locomotive and military. Jim/Stafford: Early design involvement on the part of the manufacturer is the best way to make walkerturnerdrillpressparts sure the resulting component will be reliable and effective.Jeff/Tollok: Carefully review your application requirements. Shaft material, hub walkerturnerdrillpressparts material, transmittable torques, and bending moments can influence your selection of the proper locking assembly.Intelligent designWhat can DESIGNERS do when selecting and applying locking devices to improve productivity?Jeff/KTR: Obtaining comprehensive technical information will improve selection and performance. Find a manufacturer that maintains the quality of materials, dimensions, and surface finishes.Jeff/Tollok: Too often not enough questions are asked, and selections are made based on previous designs. Don''t use the same locking assembly simply because it was used elsewhere on the same machine or on a previous machine design. Involve your supplier and use their experience to get recommendations.
