Roller Chain Couplings - Cross & Morse

1 8 MisalignmentMaximum angular misalignment is 1 , but for maximum life angular misalignment shouldnot exceed 1/2 . Refer to sketch on right, where .009mm per mm root dia. is equivalent to 1/2 angular A = .009 x or Parallel misalignment should not exceed 2% of Chain Chain CouplingsCross & Morse Roller Chain Couplingsconsist of threehigh strength components; two special Chain sprocketsmanufactured from high quality medium carbon alloysteels connected by a length of high strength DuplexRoller Chain . The sprockets have precision cut teeth,induction hardened for maximum service life;available either plain bore or machined for taperbores to provide ease of assembly.

2 Size for size anLRC Roller Chain coupling correctly lubricated is oneof the strongest Couplings available providing thefollowing design advantages:- Ease of InstallationThe LRC coupling can be quickly installed and shafts are easily separated by removing the springclip connecting link and then the Chain from the sprockets. High CapacityObtained through use of hardened tooth sprockets, MorsePrecision Roller Chain with hardened rollers, allowingsubstantial kW Power in a compact size InexpensiveLow initial cost per kW Power transmitted, and long servicelife are obtained through the use of standard components withhardened working surfaces.

3 Minimum MaintenanceWhen optional spun covers are used lubrication is retained onthe hardened working surfaces. FlexibilityGood installation practice dictates that coupling be installedwith a minimum of misalignment. The LRC coupling permitsmoderate angular and parallel shaft maximum service life, Couplings selected with ratings to the right of the heavy line in table must be lubricated with a cove speeds are indicated by heavy broken and power capacities at slow speeds for TB series Couplings are governed by taper bush addition to the standard sizes, Roller Chain Couplings can be furnished in a wide range of sizes forspecial designs with Torque Ratings of up to 2000 rpmNmRevolutions per Power Ratings - Stock Roller Chain CouplingsT e l.

7 A felt pad locatedbetween Chain and cover retainsgrease lubrication. Rounded exteriorof the cover combines safety with neatappearance. Covers are also suited tothe LSC inverted tooth Couplings . Forapplications where aluminium is notpermitted, spun steel covers of samedimensions can be supplied to Aluminium CoversFor more demanding applications,cast aluminium covers extend life ofcouplings by providing continuouslubrication and full protection fromabrasive elements. The two halves fitaround the coupling and connect by Nyloc cap-head bolts. Neopreneseals are fitted to seal betweensprocket hub and cover.
