Specifications

Materials: The elastomer used in Dynafl ex LCR Series Couplings is high-quality natural rubber, which meets LORD specifi cations (available upon request) and exceeds SAE standards. Natural rubber is used because of its excellent physical properties such as tensile strength, tear and abrasion resistance, fatigue resistance and low temperature characteristics. Other elastomers are available to meet special applications needs. The elastomer-to-metal bonds are even stronger than the elastomers.

Dynafl ex LCR Series Couplings listed on the following pages have aluminum alloy inserts. Many other insert confi gurations are possible to meet attachment requirements.

Environmental: Ring-type couplings will perform satis- factorily when exposed to the normal fl uid, temperature and other environmental conditions found in drive- line systems. Special oil-resistant elastomers can be provided where total or partial oil immersion is necessary. For operation in ambient temperatures exceeding 170°F (77°C), consult LORD Engineering.

Misalignment: Misalignment capability applies for speeds up to 3500 rpm. Operation up to 7000 rpm is permitted with reduced misalignment (consult LORD Engineering).

Note: For speeds above 4000 rpm, shielding is required and/or balancing of assembly may be required.

Installation: Normal installation involves simple through bolt attachment to fl anges. For fl ywheel attachment appli- cations, metal inserts can be tapped/counter-bored to permit easy installation.

Remote Driven Units: Multiple U-joint shafts (especially longer shafts) and the speed at which the shaft rotates (especially higher rpm’s) can create complex stability problems. To assure satisfactory coupling performance, all design layouts for remote mounted driven units should be reviewed by LORD Engineering. LORD analytical capability is only one part of the engineering service available on all coupling applications.

LCR ring-type couplings can be selected based on horsepower or maximum torque requirements. The data listed on the next page provides the necessary informa- tion to select a coupling and design it into your system.

New equipment designs and retrofi ts involving recipro- cating engine drives and unusual driveline arrangements should be analyzed to avoid potential vibration and misalignment problems. Contact LORD Engineering for assistance.
