| Made of high quality, closely grained Cast Iron, elegant in look, sturdy in design, all joints are Machined to
make the casting oil tight & dust proof.
OUTPUT SHAFT
Made of Alloy Steel duly hardened & Journals ground to close limits.
GEARS
Made of high quality Alloy Steel, hobbed profile with correct tooth contact pattern for efficient loading,
case hardened and bore ground.
BEARINGS
Metric Bearings taking care of Radial & thrust loads - Pre loaded, wherever needed.
COOLING
Heat dissipation is achieved by large surface area & Lubrication by splash type.
QUALITY CONTROL
Strict quality control at each stage of manufacture and testing.
ELECTRICALS
Geared Motor can be fitted with Electric Motor of special design like flame-proof construction, crane-duty motor, extended shaft motor, electro-magnetic brake duly fitted, oil motor etc. Standard units are fitted with TEFC. Squirrel cage induction motors suitable for 415 Volts, 3 Phase, 50 c/s (-3%) A.C. supply.
TESTING
All Components are thoroughly inspected at various stages and assembled unit is tested on "No-Load", for Noise level, oil leakage, Output speed and Temperature.
LUBRICATION
Before use, the gearboxes, with oil lubrication must be filled with the right quantity of oil by the Customer. For this purpose, the gearboxes are supplied with level, drain and breather plugs. Please specify the proposed mounting position to facilitate correct positioning of the plugs.
The Recommended oil is SAE 80 (or) its equivalent for normal working conditions. Refer to us for abnormal conditions.
INSTALLATION
For the installation of the gearbox the following guidelines should be observed:-
• The gearbox to be securely bolted to a rigid base to avoid vibrations.
• If shocks, extended overloads or jamming is expected hydraulic couplings, torque limiters, clutches etc.. should be fitted.
• If the gearbox is to be spray-painted use masking tape to shield the oilseals to prevent damage to them by the paint.
• Any gears sprockets or pulleys being fitted to the input or output shafts must have their bores machined to ISO H7 tolerance. The shafts are provided with threaded hole to facilitate the use of tie-rods with back plate and nut to push on the gears or sprockets being fitted.
• In order to avoid the oxidation and the possible seizing of the above parts, before assembly, clean both contact surfaces and apply water repellant grease or similar material.
• Bore of hollow shaft of gearbox has tolerance H7, all shafts being fitted usually are machined to H6. If required for the application interference fit (H7-J6) can be used.
• Before starting the machine, be sure that the lubricant level is correct for the mounting position of the gearbox and the lubricant viscosity is correct for the kind of load. |
