9、ANDARD JIS B 1754 : 1998 (IS0 8579-2 : 1993) Acceptance code for gears- Part 2 : Determination of mechanical vibrations of gear units during acceptance testing Introduction This Japanese Industrial Standard has been prepared based on the first edition of IS0 8579-2 Acceptance code for gears-Part 2 :
10、 Determination of me- chanical vibrations of gear units during acceptance testing published in 1993 with- out modifying the technical contents. 1 Scope 1 . 1 This Standard specifies the methods for determining mechanical vibration of individually housed, enclosed, speed-increasing and speed-reducing
11、 gear units. It specifies methods for measuring housing and shaft vibrations, and the types of in- strumentation, measurement methods and testing procedures for determining vibration levels. Vibration grades for acceptance are included. It does not include torsional vibration measurements of a geare
12、d system. This Standard applies only to a gear unit under test and operating within its design speed, load, temperature range and lubrication for acceptance testing at the manufacturers facility. The gear unit may be tested at another location if agreed upon and operated in accordance with the manuf
13、acturers recommendations. Other International Standards on vibration evaluation may be required for measuring gear unit vibration in field service. This Standard does not apply to special or auxiliary drive trains, such as inte- Note 1 Acceptance limits for tests of these types of equipment should b

However, if negotiated, this or other appropriate standards may be applied to such equipment. grated gear-driven compressors, pumps, turbines, etc., and power take-off gears. 1 . 2 Special provisions may be required for vibration measurements: the type of measurement and
15、 acceptance level should therefore be agreed between the manu- facturer and purchaser at an early stage of negotiation. 2 Normative reference The following standard contains provisions which, through reference in this Standard, constitute provisions of this Standard. The most recent edition of the s
16、tandard shall be applied. JIS B 0153 Remarks : Glossary of terms used in mechanical vibration and shock IS0 2041 : 1990 Vibration and shock-Vocabulary is identical with the said standard. 3 Definitions For the purposes of this Standard, the definitions of the following apply. For the convenience of
17、users of this Standard, some definitions are quoted from IS0 2041 and JIS B 0153 : 1985.
