Basic Information

Page 2

Selection and Sizing IMS parallel shaft reducers have been designed specifically for hoist and crane applications, following the design guidelines in AGMA 6013-A06 and CMAA-70. The gearing is designed with coarse pitch through hardened gears to provide a much higher safety factor against gear tooth failure when compared to standard commercial gearboxes. Overloads The maximum momentary overload or starting load must not exceed 200% of the rated load of the reducer. If an overload or starting load greater than 200% is required, please contact IMS for assistance in selecting a reducer. Reversing Applications involving more than 20 reversals per a 10 hour period should be referred to IMS. For hoist reducers, lifting and lowering motions create contact on the same gear flanks so reversing does not require consideration. Brake Equipped When a gear drive is equipped with a dynamic braking system that is used to decelerate system motion, select the drive on the brake rating or the highest equivalent power, whichever is greater. If the gear drive is equipped with a static holding brake, the brake rating must be no more than 200% of

the reducer rating. If the gear drive is equipped with two static holding brakes, then both brakes together must not exceed 200% of the reducer rating. For assistance with selecting a reducer for brake equipped applications, please contact IMS. Oversize Prime Movers AGMA published service factors do not account for applications with oversized prime movers for either high energy requirements or peak load requirements. Please contact IMS for assistance in selecting a reducer for an oversized prime mover application. Mounting Position The standard mounting position for IMS reducers is with the base mounted horizontally. Refer all other special mounting requirements to IMS. People Conveying IMS reducers are not designed for applications whose main purpose is the moving or lifting of people. This includes applications such as freight or passenger elevators, escalators, man lifts, work platforms, and ski lifts. Environment The standard IMS reducer is designed to operate in a protected location with reasonable ventilation; free from extreme temperatures, severe dust, toxic, explosive, or other unusual environments.



Selecting a Reducer for a Hoist

Page 3

Hoist Applications The hoist reducer tables located in the catalog apply to CMAA Class “D” hoist duty only. A Kwh factor of 0.67 was used to generate the table and assumes a loadblock weight of no more than 3% of the hoist capacity. Do not use the hoist reducer tables if any of the following apply and please contact IMS for assistance: The CMAA Class is more severe than Class “D” - for example Class “E” or “F” The loadblock weighs more than 3% of the rated capacity. A below the hook lifting device used regularly. A bucket or magnet is attached to the hoist. Bearing L10 lives greater than 10,000 hours are required. Step 1 - Determine the target ratio based on the required lift speed and selected motor speed. Step 2 - Calculate the maximum required power at the reducer input based on required lift

speed. Include efficiency losses for both the reeving and the reducer. The reducer efficiency can be assumed to be 0.9127.

Step 3 - Select the appropriate hoist reducer from the tables based on input speed (1750 or 1150) and required power to lift the load. Insure the chosen reducer capacity meets or exceeds the maximum required power to lift the load.

Step 4 - Determine the exact ratio of the selected reducer from the exact ratio table, recalculate the actual lift speed, recalculate the actual power needed to lift the load, and insure that the selected reducer capacity meets or exceeds the actual power required to lift the load.

Step 5 - Check to insure the peak load does not exceed 200% of the of the selected reducer rating.

Step 6 - Check to insure the applied overhung load does not exceed the overhung load capacity of the reducer.

Step 7 - Check dimensional information and the weight. Step 8 - Finalize the configuration of the reducer.



Selecting a Reducer for a Bridge Travel Drive

Page 4

Bridge Travel Applications The bridge travel reducer tables located in the catalog apply to CMAA Class “D” duty only. A Kwb factor of 0.85 was used to generate the table. Do not use the bridge travel reducer tables if any of the following apply and please contact IMS for assistance: The CMAA Class is more severe than Class “D” - for example Class “E” or “F” The Kwb factor is greater than 0.85. Bearing L10 lives greater than 10,000 hours are required. Step 1 - Determine the required motor power for the travel drive based on the CMAA

calculations. The reducer efficiency can be assumed to be 0.9127. Select a motor power with a capacity greater than or equal to the required motor power.

Step 2 - Determine the target ratio based on the required travel speed and selected motor speed.

Step 3 - Select the appropriate hoist reducer from the tables based on input speed (1750 or 1150) and the nameplate power rating of the selected motor. Insure the chosen reducer capacity meets or exceeds the nameplate power rating of the selected motor.

Step 4 - Determine the exact ratio of the selected reducer from the exact ratio table, recalculate the actual travel speed, recalculate the actual power needed, and insure that the selected motor power is still appropriate and that the chosen reducer capacity meets or exceeds the nameplate power rating of the selected motor.

Step 5 - Check to insure the peak load does not exceed 200% of the of the selected reducer rating.

Step 6 - Check to insure the applied overhung load does not exceed the overhung load capacity of the reducer.

Step 7 - Check dimensional information and the weight. Step 8 - Finalize the configuration of the reducer.



Selecting a Reducer for Other Applications

Page 5

Other Applications The AGMA rated reducer tables located in the catalog are for selecting the IMS reducer for applications other than hoist or bridge travel reducers. The ratings shown are for a 1.0 SF rated per AGMA 6013-A06. Step 1 - Determine the required service factor using the service factor table. Base the

selection on the type of application, type of prime mover, and average running time per day.

Step 2 - Determine the required reducer rating by multiplying the required power by the selected service factor.

Step 3 - Select the appropriate reducer from the tables based on the required reducer rating. Step 4 - Check to insure peak loading does not exceed 200% of the selected reducer rating.. Step 5 - Check that the thermal rating of the reducer is greater than the motor power rating. Step 6 - Check to insure the applied overhung load does not exceed the overhung load

capacity of the reducer. Step 7 - Check dimensional information and the weight. Step 8 - Finalize the configuration of the reducer.

Thermal Capacity Check The IMS thermal ratings represent the transmittable power, without service factor, that can be continuously transmitted by an IMS reducer without causing the oil sump to raise above 200 °F when operating at sea level and at an ambient temperature of 100 °F. The thermal rating for each reducer should be adjusted by the appropriate modifying factors to determine the thermal rating for the IMS reducer, given the application considerations.

The following example provides information to configure a part description for a reducer.


Shaft Rotations The IMS three stage reducer output shaft rotates in the opposite direction than the input shaft, when viewed from the same side of the reducer. So an input shaft that rotates CCW will produce a CW rotation on the output shaft.

Output Overhung Load Capacities & Reducer Thermal Ratings

Overhung Load The maximum allowable overhung load (OHL) for the output shaft is found from the table above, based on the gearbox size and the OHL location. The overhung load location is specified from the end of the output shaft. Use linear interpolation for distances located between those provided in the table. The values shown are for “worst-case” loading. If the allowable OHL shown in the table does not meet the application requirements, contact IMS for a more detailed OHL analysis.
