Lovejoy coupling size chart

The goal of this handbook is to assist you with the process of sorting out the myriad of coupling styles that exist to select the one best suited to your application. This handbook is not a textbook.

Safety Warning When using Lovejoy products, you must follow these instructions and take the following precautions. Failure to do so may cause the power transmission product to break and parts to be thrown with sufficient force to cause severe injury or death. Refer to this Lovejoy Catalog for proper selection, sizing, horsepower, torque range, and speed range of power transmission products, including elastomeric elements for couplings. Follow the installation instructions included with the product, and in the individual product catalogs for proper installation of power transmission These couplings require no lubrication and provide highly reliable service for light, medium, and heavy duty electrical motor and internal combustion power transmission applications. Lovejoy offers four types of elastomer designs to allow for additional flexibility in addressing specific application requirements.

The elastomer is stronger in compression than in tension.

The goal of this handbook is to assist you with the process of sorting out the myriad of coupling styles that exist to select the one best suited to your application. This handbook is not a textbook. There are several of those in print which do a great job and are very useful for coupling designers. What we are attempting to do is to provide down-to-earth useable knowledge. We want to arm you with information that you need to utilize the variety of styles that exist in flexible couplings to your best advantage and solve real world problems. Lovejoy has been manufacturing couplings since More importantly, we have the greatest breadth of coupling types offered by any single manufacturer in the world. Since couplings are our strategic focus, we feel you will find this handbook to be a valuable resource. A flexible coupling connects two shafts, end-to-end in the same line, for two main purposes.

Each hub includes a set screw unless noted , which bites into your shaft to hold the coupling in place. A complete coupling consists of two hubs and one spider, or two hubs, one split spider, and one retaining ring all components sold separately. Twist-lock them in place using a retaining ring.

The load cushions are in sets of 6 to 14 pieces depending on coupling size. Adaptability of Design — Some couplings are available in a variety of configurations e. First, determine what attributes beyond those basic criteria will be required for your application. Placing the flex point close to a bearing also helps keep the system stable. An example of a lower horsepower application is the electric motor driven reciprocating compressor. An overload will fail an infinite-life coupling but may only reduce the life of a finite-life coupling. Jaw Type Catalog 28 Pages. Increasing the distance between flex point and bearing invites vibration, or wobble. Several designs of couplings were developed to solve the problem of damping torsional vibration. The elastomer shape used in the coupling is very important for damping and damping is an important attribute for the torsional coupling. The total unbalance of the assembly at that point would depend on the distribution of the individual high points within the assembly. When the flex hub is on the equipment shaft it is called a reduced moment style.

For instance, lubricated couplings will require periodic checks of the seals and lubricant. Applied torque causes a shaft and its connected components to rotate at a certain RPM revolutions per minute. Reciprocating Drivers and Loads — Due to torsional pulses generated by reciprocating engines most notably diesels as well as certain kinds of pumps and compressors, coupling selection is generally limited to a few elastomeric types capable of damping the pulses and providing reasonable service life. That leads to the next process. Catalog ratings are often accompanied by speed limits in RPM. Gear couplings can be configured to do special jobs. Various pressure angles were used that walked the line between life and strength. For power transmission it is the torque applied and rotational distance per unit of time. Other specifications could allow body fit bolts to carry the load in shear, although from an engineering standpoint the concept of carrying load on bolts in shear is not favored. While the hub and sleeve teeth are cut to fit loosely side to side, they are cut to fit closely where the tip diameter of the hub teeth meet the root diameter of the gaps between the sleeve teeth.
