Helical GearBox

QUALITY ASSURANCE :

"Tecon" Brand gearboxes are manufactured since 1973. We are committed to the quality and ve have earn a reputation from most of our valued clients. We provide immediate service through experienced engineers, whenever required. We have a team of professional people who work together & produces the products which is used in different industries & in different application. A few thousands of gearboxes are installed in last 25 years. We are in continuous research & development & bring out the best products for different industries. We have achieved to a stage where we believe in the concept. "Nothing attracts customer like quality."   

General :
"Tecon" single reduction worm gear units are manufactured in different sizes and ratios in adoptable type as well fix foot-mounted type to meet the requirement of almost every industry. Due to robust construction, increased dfficiency, flexibility, interchangability, compactness, dependability and reliability. These units are suitable for severe operating conditions by means of right selection.

Selection :
Please refer Horse Power Rating Table and determine the size of the particular units either by way of input horse power or output torque. The ratings are based on Unity factor of 12 hours continuous running under uniform load subjected to recommended lubrication and temperature limitation of 90º C.

Specifications :
B. S. and I. S. Standards are used as applicable. The gear totally confirms to B. S. 721/1963 and I. S. 3734-1966 for worm gearing.

Gear Housing :
Gear housing is made of close grain top quality cast iron liberally designed to store adequate quantity of oil so as to achieve higher termal ratings. It is provided with large cooling fins on both sides with maximum surface area exposed to atmosphere for improved efficiency. Bearing housings are perfectly bored to ensure perfect alignment. The housing is totally dust proof and oil tight.

Worm :
Worm and worm shaft is of single piece accurately made out of high grade alloy steel and is highly polished.

Worm Wheel :
The worm wheel is made of cast phosphorous Bronze (confirms to PB-2C as per BS 1400) rim shrunked and screwed on central cast iron boss. Teeth are accurately hobbed by generating process. To facilitate interchangability, each worm wheel is inspected to match the master piece.

Bearings :
The worm and worm wheel shaft are supported on ball or roller antifriction bearings of ample capacity to permit over hung and shock loads. Provision is made for additional roller bearings in case of heavy over hung loads.

Shaft :
Shaft is made of high grade alloy steel suitably designed to withstand high torque and bending loads.

Oil Seals :
Superior quality oil seals are used to ensure complete oil tight.

Lubricantion :
Gears and bearings are automatically and positively lubricated at all speeds by splash of oil from the sump. Thus no special attention is necessary except periodically checking the oil level. (A separate oil indicator is provided)

Cooling :
Heat dissipation is effectively controlled by increased oil capacities and alarge gear case surface area exposed to air. The fan mounted on the worm shaft induces continuous air flow which increases heat transfer for improved efficiency.

Efficiency :
Higher efficiency is achieved by correct design, careful selection of material lubrication and through inspection. Every gear is checked for silecked for silence and oil tightness. The efficiency for samaller gears (upto 3" centre) varies from 60% to 93% depending on the ratio whereas in bigger sizes (4" centre and above) it varies fro 70% to 96%.
