Lovejoy L-190 Jaw coupling replacement, the TSC500.
TSC500 3/4″ coupling replacement for L-190 jaw coupling users.
Lovejoy L-190 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), 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 Lovejoy L-190 is broken down across two Twin Spring Coupling models, The Sox and Urethane models with the TSC300 and the Hytrel and Bronze with the TSC500 model.
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 coupling and universal joint has not.
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 Lovejoy L-190 jaw type couplings.
- 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 bearing cross greased or they too will wear out quickly. Both friction bearing and needle bearings need to be replaced due to wear.
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 that’s going to create interruption and a increased annual maintenance bill.
Lovejoy L-190 how the TSC500 is a better alternative.
Twin Spring Coupling has no internal components so no annual maintenance and can run at high and low speed as needed.
Our coupling is available in all the standard industry splines for easy replacement or retrofit for OEM. Now in Metric sizes
Flexible up to 25 degrees.
Speeds of up to 7000 rpm.
Constructed of 4140 Alloy.
