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."
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
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.
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 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 and worm
shaft is of single piece accurately made out of high grade alloy steel
and is highly polished.
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.
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 is made
of high grade alloy steel suitably designed to withstand high torque and
Oil Seals :
oil seals are used to ensure complete oil tight.
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)

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%.
