Lovejoy L-100 SOX/Buna-N/Urethane 1 1/4″ Jaw coupling alternative, the TSC150 1 1/4″ coupling.
TSC150 1 1/4″ jaw coupling alternative. Replace your Lovejoy L-100 with a maintenance free, flexible shaft couplings alternative.
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, Hytrel and Bronze spider inserts 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), 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 power transmission couplings are universal joints which can normally only run at 4° otherwise prematurely wearing the bearings within the propeller shaft of the universal joint.
The bearing races will start to wear on the outside which means the ball bearings will become loose and that creates vibration and with continual wear the ball bearings will fail.
The bearings need also to be constantly greased otherwise the ball bearings will not have any lubrication, and with them running at high speed the balls will seize in their tracks again leading to bearing failure.
Jaw couplings the spiders wear after use of 1° 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 universal joint are the yokes which the bearings are contained in, the coupling piece of the yokes are quite tough but the section that contains the bearings not so much as they have to hold the bearings.
This is a weak point as the bearings are usually less than 2″ across so the machining to contain the bearings is a lot smaller than the rest of the yoke, which means the likely of them cracking is that much higher.
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 SOX replace with TSC150.
Twin Spring Coupling is different it replaces the entire jaw coupling, hubs, spider inserts, 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 L-100 joints.
Our coupling is available in all the standard industry splines for easy replacement or retrofit for OEM. Metric sizes now available.
