Lovejoy L-150 3/4″ Urethane jaw coupling replacement – the TSC300.
TSC300 3/4″ jaw coupling replacement for jaw coupling users, replace your Lovejoy L-150 Urethane with a maintenance free, flexible shaft coupling alternative.
Couplings in the industrial sector traditionally are broken into two sectors, jaw couplings that can only run at angles of 1° or less otherwise they wear out, as they cannot physically flex beyond that, normally they run at 1/2°. The other are universal joints.
Lovejoy L-150 Jaw couplings are a 3 piece elastomeric coupling, an input and output hub and a spider insert, the insert can be made up of 4 different materials SOX, NBR, Buna-N, Urethane, Hytrel and Bronze.
Each insert gets progressively stiffer and less able to absorb vibration so the angular misalignment becomes smaller with each insert.
Couplings in an industrial power transmission setup have a number of issues to contend with, annual maintenance, fundamental design flaws coming from a century old technology, industry has evolved but the technology that makes up the standard jaw coupling.
Twin Spring Coupling offers something different.
Industrial power transmission is broken into two main areas, high speed low angle of misalignment and lower speed higher angle of misalignment. Traditionally these two needs have been service by two different couplings – Motion control couplings like jaw couplings and the universal joint.
The problem with both couplings are their fundamental design weaknesses, for motion control coupling they can run fast but cannot work at over 4 degrees of misalignment before they start to wear out.
The universal joint can run at more than 4 degrees but needs constant maintenance to keep the bearings and block greased or they too will wear out quickly.
On top of that they traditionally cannot run over 8 degrees before technical issues like balancing and bearing wear become issues. In a 24/7/365 situation like industrial power transmission couplings that’s going to create interruption and a increased annual maintenance bill.
Lovejoy L-150 verses the TSC300 how it’s different.
The one piece design means no greasing, no replacing components just a annual checkup, vital in industrial 24/7 applications.
