Lovejoy L-100 1/2″ NBR / Buna-N / Nitrile rubber Jaw coupling alternative, the TSC150.
TSC150 1/2″ maintenance free jaw coupling alternative, replace your Lovejoy L-100.
Couplings in the industrial sector traditionally are broken into two sectors, the elastomeric couplings that can only run at angles of 1° or less, as they cannot physically flex beyond that, Bronze and Hytrel spider insert normally can only run at 1/2°.
Lovejoy L-100 Jaw couplings are a 3 piece elastomeric coupling, an input and output hub and a spider insert, the insert can be made up of 3 different materials SOX – (NBR / Buna-N / Nitrile rubber insert), Urethane, Hytrel and Bronze.
Each insert gets progressively stiffer and less able to absorb vibration so the angular misalignment becomes smaller with each insert.
The other are the two types of universal joints which can normally only run at 8° otherwise prematurely wearing the bearings (friction bearings or needle bearings) within the propeller shaft of the universal joint.
The bearing will start to wear and will become loose and that creates vibration and with continual wear the bearings will fail.
The inserts need also to be replaced otherwise the two hubs will contact each other leading to a huge uptake in vibration potentially damaging delicate equipment especially with them running at high speed.
Jaw couplings the spiders wear after use of 1-2° and yokes can crack.
Twin Spring Coupling can run up to 25° without needing to be lubrication, and at low angles of misalignment and comparable high speeds to traditional industrial couplings.
Ball bearings being very precise instruments also need to be contained to ensure infiltration by any foreign contaminants, as things like water, mud, dust or dirt will again cause the ball bearings to seize in their tracks and this means bearing failure.
Being used at high speed for long periods of time produces heat and that can cause the ball bearings to seize inside the bearings leading to premature failure.
The other downside to a jaw coupling are the hubs which the spider insert sits in the middle of absorbing vibration and allowing a small amount of flexibility, the insert usually made of materials like SOX, Urethane and rubber compress over time and need to be replaced regardless of wear.
Cracking leads to catastrophic failure and replacement of both the yoke and universal joint is assured. This makes it an expensive repair as with the price of the yoke and universal joint, it is usually cheaper just to replace everything, both yokes and the propeller joint.
Lovejoy L-100 alternative.
Twin Spring Coupling is different it replaces the entire U joint, yokes, propeller/cross bearings everything, with a simple one piece design.
By being a one piece design also means Twin Spring Coupling wont break like the yokes do in traditional Lovejoy L100 joints.
Our coupling is available in all the standard industry splines for easy replacement or retrofit for OEM.
Speed Up to 7000 rpm.
Constructed of 4140 Alloy.
