Product Description

Industrial Gear Couplings:::::::::

An immaculate and long range of high quality Gear Couplings is offered by us at competitive as well as leading industry rates. The couplings are flawless and ideal to be used in different industries due to its attractive and beneficial features like solid structure, accurate dimension, fine finish, excellent abrasion & corrosion resistance etc. Furthermore, we offer them in different specifications including customization as per the requirements of the customers.

Nu-Teck manufactures straight tooth Gear Coupling and Tripple Crowned Teeth Gear Coupling.

Disadvantage in Straight Tooth Gear Couplings are

  • Under the misalignment condition of two shafts of the equipments, the teeth contact in case of straight cut hub will be as minimum as shown in the fig No.1
  • Under heavy loads the ends of the hub teeth will get damaged resulting in the excessive play between hub & sleeve and therefore the reduction in life of coupling

Nu-Teck Tripple Crowned Teeth Gear Coupling

  • The triple crowned teeth hub is manufactured on a fully automatic hobbing machine with built in crowing attachment which is controlled by hydraulic & electronic systems.
  • Under the misalignment condition of two shafts on the equipment, due to the curvature on teeth flank the contact area is much more and therefore, there is increase in life of coupling.

Misalignment Details: In case of straight tooth gear coupling the maximum allowable angular misalignment ( ) is 1.1/2 deg. and in case of NU-TECK Triple Crowned tooth Gear Coupling the misalignment is 3.1/2 deg.

NOTE

  • Made to order / special Gear Coupling also can be manufactured
  • Dynamic balancing & Heat Treatment will be done on request
  • We also manufacture gear coupling with spacer & cordon shaft.

How to select the right Nuflex Gear Couplings ?

  • Select the size Nuflex Coupling that will accomodate the diameter of the largest shaft. Usually this will determine the proper size Coupling for your condition.
  • To make sure this Coupling has the required capacity:
  • a) Check your application against the Service Factor Chart. Use the following formula to ontain HP per 100 RPM of your application

HP x Service Factor x 100 / RPM = HP / 100 RPM

Lubrication

Gear Couplings must be filled with proper grade of Grease or Oil while installation and periodically also. It is recommanded to use grease where the maximum temperature is within 80 oC and for temperature above 80 oC oil should be used. We suggest to use following grades of grease / Oil for a good performance.

For speed above 1500 RPM use oil SERVOMESH A-90 of Indian Oil Corporation having viscosity 91 C/S at 100 oC or of 324 = 35 cst/50 oC (43 o Engler / 50 oC) OR equivalant.

For lesser speeds use grease with high pressure additives like SERVOPLEX EP - 1 of Indian Oil Corpn. or SHELL ALVAMIA EP - 2 or lithium/sodium grease with EP / additives drop over 180 degree C grade of penetration.
