Products - Worm Reduction Gear Boxes

Gear Case
Gear Case is made of close grain cast iron.It is completely oil tight & dust proof.and capable of installation in open without separate covers.The face and bores are perfectly alignned & interchangeable.They are machined on fully automatic CNC Horizontal Machining Center

Worm
Worms are generated on high quality case hardening steel accurately generated, ground and super finished on fully automatic "7 AXIS CNS WORM PROFILE GRINDING MACHINE"

Worm wheel
Worm Wheel are hobbed on latest fully automatic gear hobbing machine with high accuracy hobs.

Worm Wheel shaft
The wheel shaft is made of carbon steel and machined on fully automatic turning center,with high quality case harding.

Bearing
Both the shafts are located on dual purpose bearing on ample capacity and having substantial margin on out put shaft for accommodating over hung loads.

COOLING
For air cooling we use standard polypropylene fans which direct a continuous flow of air over the ribbed surface of the gear unit.

Note:3.5"HU *A2:-193 x 205 *B2:-238 x 250 4"HU A2:-212.5 x 235 * B2:-260 x 285

These Dimensions are for preliminary use only & are subject to our confirmation keyways as per IS 2048 Shaft limits up to 58 dia k6 & above 58 dia m6.

Selection

The Size of unit is selected by rating table using input horse power or out put torque for appropriate input & output speeds. Rating are based on a service factor of i.e.:12 hours continuous running per day with maximum working oil temperature of 90* c with normal overload at 100% momentary 50% up to 1 minute 25% up to 2 hours will carry normal overload borned by ISI standard A.C.motors

Product Safety Information

	General HEENA gear units will operate safely provided that they are selected, installed, used and maintained property. As with any equipment consists of rotating shafts and tranmitting power, adequate guarding is necessary to elimiate the possibility of physical contact with rotating shafts or couplings.

Potential Hazards
	The Following points should be noted and brought to attention of the persons involved in the installation, use and maintenance of equipment 1.For lifting of geauit eye-obolts or lifting points (on larger units) should be used 2.Check the grade and quantity of lubrication before commissioning. Read and carry out all instructions on lubricant plate and in the installation and maintenance manual literature. 3.Installation must be performed in accordance with the manufacturer's instruction and be undertaken by suitably qualified personnel. 4.Ensure the proper maintenance of gearboxes in operation USE ONLY HEENA SPARES FOR GEAR-BOXES 5.The oil level should be examined periodically, if required the oil should be filled again. 6.The operating speeds, transmitting powers, generated torques or the external loads must not exceed the design values. 7.The driving and the driving equipment must be correctly selected to ensure that the complete installation of the machinery will perform satisfactorily E.G. avoiding system critical speed system and torsional vibration etc.
