Resilient Coupling
Hi Torque Resilient Couplings
"GBM HI -Torque"Type Resilient Couplings are in use in all
types of industrial applications over many years with success.
Such a Resilient Coupling comprises mainly two Hubs, Grid Spring
and Covers to protect the Spring. The Grid Spring element is so
designed that it provides required resiliency for variable
flexibility of a Coupling and considerable damping properties
making the Coupling very suitable for drives involving high
shock loads to the extent of 80%. Misalignment that inevitably
occurs between rotating shafts, which are independently
supported, is also taken care of by the spring element within
allowable limits.
Dimensions given in the tables are approximate and pertain to
Standard Coupling of GBM range, but tailor-made Couplings with
Hubs of longer or shorter lengths, Seals & Grub Screws can also
be supplied as per requirement of individual customer. Following
service information must be furnished with enquires:
1. H. P. & R. P.M. of the Drive.
2. Types of driving & driven machines.
3. Nominal diameters and lengths of shaft extensions of both the machines.
4. Dimensional details of finished bores & keyways, if required.
5. Any other details relevant to the working conditions of the Drive.
Standard Coupling Types : X, Y, Z & S - Selection of Couplings :
■ Determine service factor corresponding to the type of application under consideration from the Table of Service Factors.
■ Determine the Maximum Horse Power = Normal rated H. P.x Service Factor of DRIVE.
■ Determine Rating of Coupling: =
Maximum H.P.
----------------------------------
Rated R P M of DRIVE
■ After having determined the Rating of Coupling, check whether maximum bore and recommended speed of the Coupling correspond to the requirements of the
drive. If the allowable maximum bore is too small, select a larger coupling; in case allowable safe speed is too low, a different type of Coupling will have
to be considered. You may refer to GBM for recommendation.
Lubrication : Indian Oil "Servogem 2", or, any equivalent grease is recommended for use.
For Couplings for high speed and special application, use lubricants as will be recommended individually.
Spare parts : Parts of a Hi-Torque Resilient Coupling of particular type are interchangeable with
parts of a Coupling of similar type. While ordering out spare Grid Spring or other parts, the code number/serial
number stamped on the Coupling name-plate must be furnished to ensure correct supply.
