Features

Coupling sizes availableto transmit torque loads from 60 in/lbs to over 3.24 million in/lbs with shaft capacities ranging from .375 to over 20.00 running from low rpm to over 18,000 rpm.

Close coupled, Spacer types,Limited End Float, Slide, Floating Shaft, Flywheel,Brake Wheel, Brake Disc, and made to orderengineered couplings.

Patented T-Flex® absorbs extreme torsionalshock and vibration while accommodating angular, parallel, and axial misalignment without generating reactionary loads, which significantly increases bearing life. T-Flex® uniquely combines the stability of a com- pression type coupling with the safety of a shear coupling. In the event of a lockup, the insert will shear, minimizing the possibility of damaging yourrotational equipment. No lubrication or routinemaintenance is required. The rugged polyurethaneinsert is the only spare part and can be replaced in

the shaft hubs. Standard inserts have a temperaturerange from -60° to 200° Fahrenheit with high temp-erature inserts available to over 350°. The inserts are available in a range of hardness to meet most torsional stiffness and torque requirements, andoffers very high resistance to chemicals and weather.T-Flex® couplings are suitable for blind assembly,horizontal or vertical, reversing, and stop/startapplications. The Compact size to torque ratio withgenerous bore capacity allows proper sizing. Hubsare available for use with tapered bushings, lockassemblies, shrink discs, finished bored and keyed,taper bored, and spline bored.

How it works T-Flex® close coupled couplingsconsist of four parts. The Ring Hub, Flex Hub,Insert, and Drive Ring. The Ring Hub and Flex Hubare installed on the shafts with the Drive Ring fittingover the Flex Hub. After coupling alignment, theInsert is placed around the Flex Hub engaging thebottom lobes of the Insert. The Drive Ring is thenfitted over the Insert engaging the top lobes of theInsert. The Drive Ring is then fastened to the RingHub using high strength alloy steel socket head capscrews with high collar lock washers. The couplingwill now transmit torque with silent, smooth reliable,maintenance free operation.

Manufacturing T-Flex® is manufactured in theUSA. Standard hubs and rings are machined fromsolid carbon steel rounds and tubing, maintainingtight tolerances which provides excellent coupling balance. Stainless steels in grades 303,304, and 316 are also available for corrosive environments and food applications. We also offer a low cost, FDA approved alternative to stainless steel called Melonite Process which turns carbon steel shinyblack and prevents wear and corrosion. T-Flex® inserts are made from durable customcompounded polyurethane that offer resistance toalmost every fluid found in industry today. Using T-Flex® ensures dependable, maintenance free torque transmission for your rotational equipment, and comes with product / technical support from ourknowledgeable staff with over 25 years experience.

Flexible Couplings

1) Determine service factor (SF) SF = F1 X F2 (not to exceed 4)

2) Calculate required coupling continuous torque rating (lb-in) using the formula: HP X SF X 63025 ÷ RPM = Torque (lb-in)

3) Determine suitable coupling insert type for application using the Insert Color Chart below

4) Choose the coupling size that meets or exceeds the calculated required continuous torque rating using the color coded tables below. Intermittent (peak) ratings are reserved for system torque spikes, starts/stops, reversing etc.

Insert Tables: Torque ratings (lb-in) - HP ratings @ various RPMS - Max RPM's based on insert types

5) Determine coupling type required for the application. Check dimensions/max bore tables to confirm the coupling sized will accommodate shafts and physically fit the application. Determine if the couplings hubs will be bored to size, or used with Taper Lock Bushings, QD Bushings, or other type of locking device. Standard couplings are machined carbon steel. Specify if stainless steel or Melonite Process is required based on atmosphere conditions, etc.

Flexible Couplings

FIGURE 2SPACER

Non-Spacer couplings are easily coverted to Spacer Couplings simply by adding the spacer body. All other components are standard. Spacer Length (SL) = DBSE - E to allow proper gap. See Table 2 for standard stocked spacer lengths.

Note: Size T-6 thru T-12 spacers are made to order. Special inventory arrangementscan be made with the end user if needed. Consult Factory for Min/Max spacer lengths

MB HD: Use the Heavy Duty Ring Hub for shaftslarger than MB RH. RH HD must be specified when ordering RSB for the larger shafts. Available for use with Spacer and Non-Spacer Couplings

FIGURE 4HEAVY DUTY RING HUB

Note: T-Flex standard couplings are designed to allow free axial movement of driver and driven shafts. Limited End Float couplings should be specified for all applications requiring limited or controlled axial end float such as Sleeve/Babbit bearing motors, fans, blowers, etc. Consult factory for questionable applications. Limited End Float Flex Hub and Inserts are used with standard Ring Hubs and Drive Rings. Available for use with Spacer and Non-Spacer Couplings.

ATR Sales Inc. reserves the right to change design without notice. The dimensions and weights listed are approximate and sufficient for most users. Dimensions L3 and L4 may be faced off as needed for length restrictions. (see page 12 for shaft contact) The purchaser should request

certified prints for couplings requiring tighter tolerances, critical dimensions and/or weights. Contact ATR Sales @ 800-443-6613
