L type hubs are used with L type spiders to form L type couplings for accommodating parallel & angular misalignments between two rotating shafts. The keyway-type hubs provide a fail-safe design by ensuring a secure connection with shafts.
This product can only be shipped in multiples of 4
Features
Specific Applications: Lovejoy L type hubs are ideal for high torque transmission and speed requirements in sprockets. They also offer highly reliable service for internal combustion power transmission and heavy, medium & light duty electrical motor applications.
Hub Design::
Fail-safe design: Even after the spider legs are sheared away, the metallic hubs will interlock and continue to transmit torque. This can be a useful feature during short-term cases of emergency.
They are bored to a clearance fit tolerance with a single keyway and supplied with a set screw for quick installation.
Coupling Size-Material Relevance:
Small-to-medium-sized hubs (L035 to L190) are made of powder metal (sintered iron). They can be pressed very close to the finished net shape, minimise downtime & cost of machining, as well as eliminate scrap production.
Large-sized hubs (above L190) are made of cast iron. They can handle higher loads.
Aluminium (AL type) and stainless steel (SS type) hubs are non-standard. The former is preferred for its lightweight and rust-inhibiting properties, while the latter is suitable for pharmaceutical and food-grade applications.
Frequently Asked Questions
Why do jaw couplings fail?
Jaw couplings fail because of the following factors - overload, normal wear, excessive misalignment, insufficient lubrication, vibration and harsh environmental conditions.
What materials are Lovejoy keyless L-type hubs made of?
These hubs feature sintered iron / cast iron construction for ensuring high compression strength and porosity resistance.
How do I find out the size of a Lovejoy coupling?
Scan down the keyway or bore column to the 2-inch bore entry. Read across the L190 column for locating the brand's UPC number - 12303. This number is prefixed with the Lovejoy UPC number - 685144.
Where are Lovejoy jaw couplings used?
These couplings are used in pumps, compressors, gearboxes, mixers, blowers and conveyors.
