"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 couplings of GBM range, but tailor-made Couplings with Hubs of longer or shorter lengths, Seal & Grub Screws can also be supplied as per requirement of individual customer.
Following service information must be furnished with enquiries --
H.P. & R.P.M. of the Drive
Types of driving & driven machines
Nominal diameters and lengths of shafts extensions of both the machines
Dimensional details of finished bores & keyways, if required.
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.
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.
Parts of a Hi-Torque Coupling of a particular type are interchangeable with parts of a Coupling of similar type.
While ordering out spare Grid Springs or other parts, the code number/serial number stamped on the Coupling name-plate must be furnished to ensure correct supply.
