Catalog excerpts

Roller Chain Couplings The LRC Coupling can be quickly installed and aligned. Connected shafts are easily separated by removing the spring clip connecting link and then the chain from the sprockets. • Minimum Maintenance Obtained through use of hardened tooth sprockets, Morse Precision Roller Chain with hardened rollers, allowing substantial kW Power in a compact size When optional spun covers are used lubrication is retained on the hardened working surfaces. Low initial cost per kW Power transmitted, and long service life are obtained through the use of standard components with hardened working surfaces. Good installation practice dictates that coupling be installed with a minimum of misalignment. The LRC Coupling permits moderate angular and parallel shaft misalignment. kW Power Ratings - Stock Roller Chain Couplings Coupling No. • High Capacity Cross & Morse Roller Chain Couplings consist of three high strength components; two special chain sprockets manufactured from high quality medium carbon alloy steels connected by a length of high strength Duplex Roller Chain. The sprockets have precision cut teeth, induction hardened for maximum service life; available either plain bore or machined for taper bores to provide ease of assembly. Size for size an LRC Roller Chain Coupling correctly lubricated is one of the strongest couplings available providing the following design advantages:- For maximum service life, couplings selected with ratings to the right of the heavy line in table must be lubricated with a cover. Maximum speeds are indicated by heavy broken lines. Torque and power capacities at slow speeds for TB series couplings are governed by taper bush limitations. In addition to the standard sizes, Roller chain Couplings can be furnished in a wide range of sizes for special designs with Torque Ratings of up to 2000 Nm. Misalignment Maximum angular misalignment is 1˚, but for maximum life angular misalignment should not exceed 1/2˚. Refer to sketch on right, where .009mm per mm root dia. is equivalent to 1/2˚ angular misalignment. B – A = .009 x C. Offset or Parallel misalignment should not exceed 2% of chain pitch.
