Flexible Couplings - Lubrication
ANSI/AGMA 9001-C18

ABSTRACT

This standard provides information on lubrication of gear couplings, chain couplings and metallic grid couplings. Types of lubricants and lubrication methods and practices are included. In addition, selection guides for grease and oil lubrication are provided.

FOREWORD

Coupling lubrication requirements are unique. Proper lubrication is an essential element for the satisfactory performance and long life of lubricated flexible couplings. Requisites for proper lubrication are: selection of proper lubricant, a well-designed lubrication system, and an adequate maintenance program. This requires the cooperation of the manufacturer, the user, and the lubricant supplier.

Work was begun on the standard by AGMA Flexible Product Group 5, Technical Committee in January 1973. To insure representation of the manufacturer, the user, and the lubricant supplier, a group from ASTM Technical Division G on Lubricating Greases was asked to participate. This standard was prepared as a joint effort of both groups. It was approved by the AGMA membership in March 1986 and approved as an American National Standard on February 18, 1987.

This revised version of the standard was approved by the AGMA membership in March 1997, and as an American National Standard on March 25, 1997.

ANSI/AGMA 9001-B97 was a revision of ANSI/AGMA 9001-A86 to include SI units along with the inch units. This revised version of the standard was approved by the AGMA membership in March 1997, and as an American National Standard on March 25, 1997.

ANSI/AGMA 9001-C18 was developed to remove the inch units and retain only the SI units. The Normative list in Clause 2 was reviewed and updated to match current editions of documents listed. Editorial clarifications were also made as needed.

The first draft of ANSI/AGMA 9001-C18 was created in April 2014. It was approved by the AGMA membership in April 2018. It was approved as an American National Standard on June 15, 2018.

 

SCOPE

Types of flexible couplings

This standard covers the lubrication of the following types of flexible couplings and generally applies to other types of lubricated couplings.

  • gear couplings;
  • chain couplings;
  • metallic grid couplings.

Some types of flexible couplings do not require lubrication for operation.

Types of lubricants

The types of lubricants for flexible couplings covered in this standard are:

  • oils;
  • greases.

Lubrication methods and practices

The lubrication methods and practices covered in this standard are:

  • Self-contained. In this category lubricants can be oils or greases.
  • Externally supplied. In this category, the couplings can be continuously supplied with oil at a specified flow rate, be dip lubricated, submerged in oil, or intermittently lubricated with oil that is replenished periodically.

Exceptions

Food and drug industry

The lubricants covered by this standard are not recommended for food and drug industry applications where contact with the product being manufactured may occur. The user shall assume the responsibility for selecting the proper lubricant, with consultation with the coupling manufacturer, for all food and drug industry applications.

Experience

Coupling manufacturer’s experience based recommendations for lubricants and lubrication methods may supersede the information provided in this document subject to agreement between the user and manufacturer.

Cooling

This standard does not apply to couplings where an oil flow is provided solely for cooling purposes.
