BS ISO 4468:2020 齿轮滚刀 精度要求

What is ISO 4468 about?    ISO 4468 is an International Standard on gear hobs and its accuracy requirements. Compliance to ISO 4468 can impart a high degree of precision and accuracy in manufacturing gears.    ISO 4468 specifies requirements for the accuracy of general-purpose hobs of 0,5 modules to 40   module. These hobs are intended for producing gears that conform to ISO 53 and ISO 54 .   ISO 4468 applies to hobs for spur and helical gears. It applies to solid (monobloc) and inserting   blade hobs.   Note: The tolerances in this document were determined for gear hobs whose dimensions conform to ISO 2490 , but with certain precautions, they can be applied to hobs not specified in...

Gear hobs. Accuracy requirements

ISO 4468:2020 齿轮盘 - 精度要求

This document specifies requirements for the accuracy of general-purpose hobs of 0,5 module to 40 module. These hobs are intended for producing gears which conform to ISO 53 and ISO 54. This document applies to hobs for spur and helical gears. It applies to solid (monobloc) and inserted blade hobs. The elemental features of hobs are graded according to accuracy, as follows: — Grade 4A; — Grade 3A; — Grade 2A; — Grade A; — Grade B; — Grade C; — Grade D. Grade 4A is the highest order of precision. In addition to the elemental tests for hobs, this document gives permitted tolerances for composite tests that are taken along the cutting edges on the line of action. The two groups of tests are not equivalent and one can choose between one or the other. If there was no previous agreement, the hob is regarded as belonging to the precision class specified if it satisfies one or the other of the two methods of inspection. NOTE The tolerances in this document were determined for gear hobs whose dimensions conform to

NOTE 1—Throughout the standard, “gear” means gear or pinion unless the gear is specifically identified. 1.1 This practice describes a two-part procedure for electromagnetic evaluation on gear teeth on mill and kiln gear drives and pinions. The first part of this practice details the ability to detect 100 % of surface-breaking discontinuities in the flank and root area on both the drive side and non-drive (coast) side of the gear tooth using an eddy current array. The second part of the examination is to size or measure accurately the length and depth of any cracks found in these areas using electromagnetic methods. No other practice addresses the use of electromagnetic methods for the detection and sizing of surfacebreaking discontinuities on mill and kiln ring gear teeth. For reference, Fig. 1 contains a schematic diagram labeling the areas of the gear teeth. 1.2 This practice is used only for the detection of surface breaking discontinuities including cracking, macropitting, and certain scuffing and wear patterns. It will not provide a full gear tooth analysis. Visual examination by an experienced gear specialist is the best way to characterize fully the failure modes present. It is imperative that the analysis of the gear teeth is completed at the time of examination. Sending data offsite for analysis later is not recommended, as potential failure modes could be missed from lack of in-situ visual examination. 1.3 Two technicians, one lead technician, and a gear technician, are typically required for this practice. One technician guides the probe and the other technician operates the computer/software and analyzes the gear teeth condition. 1.4 It is important that the appropriate method standards, such as Practice E3024 and Practice E2261, accompany the technician when performing the examination. If crack sizing is performed, then it shall be performed using an electromagnetic testing method such as the alternating current field measurement approach of Practice E2261. 1.5 It is recommended that the technician review the appendixes in this practice in advance of starting the job. 1.6 A clean gear is recommended for a complete gear analysis. Depending on the lubrication used, the technician, in discussion with the client, shall determine the appropriate cleaning procedure. If an oil bath lubrication system is used, ensure the gear teeth surfaces are clean. If an asphaltic-based or synthetic-based lubricant is used, refer to the annexes and appendices in this practice. 1.7 Units—The values stated in either SI units or inchpound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined. 1.8 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.9 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
