- Classical V-Belts |
The first of the V-belts to enter
the power transmission scenario. The
continued efforts of PIX has enabled
to achieve the power ratings
considerably higher than most of the
available in the market. The
compounds used to build up these
belts are well chosen to match the
stipulated power ratings thus
offering distinct advantages
regarding the increased factor of
safety on critical drives. The
standards followed by PIX has put
the tolerances to be much more
stringent than BS 3790, which forms
the basis of PIX classical belts.
Applications:
Primarily used as replacement on
industrial drives. The classical
belts are recommended in special
applications such as V-flat drives.
In the same manner these belts are
advantages where reverse idlers have
to be used, because of smaller
heights.
Standards, Dimensions & Product

PIX - X'set
- Wedge Belts |
Wedge
belts have been the result of a continuous thrust by
the manufacturers and users on higher power
transmissions with reduced space requirements. Wedge
belts can transmit higher power to the extent of 1.5
to 2 times the classical belts with the same top
width. This has been achieved by dimensional
changes, apart from better cord construction used
and the optimum placement of the cord line which
provides the best support to the cord while in
motion. During manufacturing we pre-strech the cord
before building into the belt. It offers lower
stretch properties in the drive. This way we are
able to reduce minimum installation and take up
allowances significantly. For the efficient
performance of wedge drive it is essential that the
proper tension be maintained in the drive, failure
to maintain the same will render the purpose of
wedge belts ineffective.
Applications:
Wedge belts are used primarily on all new drives
because of space savings achieved by using these
belts. These belts find their extensive use in all
industrial applications from light duty drives as
those for pumps to heavily loaded stone crusher
drives. In wedge belt drives, single belts can be
replaced by banded belts without changing the pulley
configuration.
Standards, Dimensions & Product Range:
We manufacture the entire range of wedge belts.
The nominal length for wedge belts is designated as
pitch length (Lp) in millimeter. |
Features:
● Top width to height ratio is 1.2:1
● Temperature range: -18°C to +80°C
● Maximum recommended belt speed is 30 m/s*
● Permissible flex rate f=100 per second
● Less deformation of the belt cross-section when in
contact with the pulleys ensures better contact
between the
belt flanks and the pulley grooves
●
Antistatic, Oil and Heat resistant
● ATEX certified FRAS belts are also available

- Narrow Belts |
In
construction and properties the narrow belts are
similar to the wedge belts in performance, with the
only difference being the additional top ridge
provided in the narrow belts. These belts are
manufactured according to specification RMA-IP 22
and also known as American Wedge Belts.
Interchangeablility Between Narrow & Wedge belts
________________
Narrow Wedge
________________
3V SPZ
5V SPB
________________
Acceptable agreement and exchangeability is found
between 3V and SPZ as well as between 5V and SPB
sections. It is possible to use 3V and 5V section
belts in pulleys of SPZ and SPB sections
respectively but corollary is not recommended as the
top width of the RMA standard pulleys are smaller.
Section 8V is however, larger than SPC. Profile SPC
may in some cases be used in grooves intended for
the 8V profile with some loss of power rating but
the opposite is not recommended.
Applications:
These sections are standardized in USA and Canada
therefore it is primarily used in machines exported
to/from these countries. 8V section belts are used
in heavy duty drives such as stone crushers.
Standards, Dimensions & Product Range:
The standard length designation for Narrow belts is
as follows:
Belt number / 10 = Outside length in inches
Example: 5V 950 means 950 / 10= 95 inches
outside length |
Features:
●
Temperature Range: -18°C to +80°C
● Maximum recommended belt speed is 30 m/s*
● Maximum flex rate is f=100 per second

DS Hexagonal Belts |
|
Hexagonal V-belts are also known as
Double V-belts. In simple terms it
can be considered as two V-belts
joined back to back. The neutral
axis containing the tension member
is exactly half way up the section.
Applications:
Hexagonal belts find their
application in the drives where
several pulleys in the same plane
are to be driven in the clockwise
and anti-clockwise direction
simultaneously. The polyester
tension cord placed at the centre of
the construction provides the belt
extreme flexibility and low stretch
properties. It is because of this
positioning of the cord that these
belts are not subjected to any other
forces as in the case of normal
V-belts. These are also used in rice
mills. However off late these belts
are rapidly finding application in
industrial drives.
Drive Calculation:
The drive calculation for double
V-belts differs from the drive
calculations of two-pulley drives.
The effective lengths, rotational
speeds, transmission ratios and belt
speeds are determined by the
effective pulley diameters. There is
no requirement of special pulleys
for these belts. We suggest that the
customer should get back to us for
assistance in using these belts.
Standards, Dimensions & Product
Range:
For all practical purposes the
length of double V-belts is
considered as the effective length
which is roughly the belt length at
the centre.
|
|
Features:
●
Temperature range: -18°C to +80°C
● Maximum recommended belt speed is 30 m/s
● Antistatic, Oil and Heat resistant

MB Banded Belts |
|
PIX Banded belts can be made by
joining either Classical, Wedge or
Narrow belts. Each band may contain
the specified number of belts. We
recommended maximum of five belts in
one tie-band.
Applications:
Banded belts are recommended under
following conditions
●
Severe vibrations
●
Vertical shaft drives
●
V-flat drives
●
Agricultural drives
●
Conveyer systems
●
Stone crushers, reciprocating

VS Variable Speed Belts |
|
PIX Variable Speed Belts are
designed for efficient power
transmission with minimised wasteful
heat generation. A special rubber
compound with textile fibres
oriented across the length of the
belt provides high stability &
minimizes deflection in the cross
section. The belts are temperature
and oil resistant as well as
antistatic. The minimum stretch
stiff polyester cords have been
designed for heavy power
transmission while at the same time
ensuring a very high degree of
length stability. The sides of the
belts have excellent abrasion
resistant properties contributing
significantly to long & useful
belt life. A moulded cog reduces
bending stresses & improves
heat dissipation in cut edge cogged
construction. |
|
Features & Benefits :
● High load carrying
capacity
● High resistance to Oil, Heat, Dust and Cracking
● Specification as per RMA IP-25, ISO-3410, BS-3733

High Power Belts |
|
|
In some
critical applications, whenever torque is applied to the
belts, they get deflected in the pulley groove.
Such deflection leads to an uneven distribution of load
across the tension members.
Therefore, it is important for the compression rubber to be
resistant to the lateral force, when entering into the
pulley grooves. We have developed belts with the
characteristics to withstand this lateral force in wrapped
and raw edge constructions which are called PIX X'set®HP
and PIX X'tra®HP as and High Power Belts
respectively.
These high power belts are designed in such a way that a
composite layer with higher modulus across the belt section
and with good flexibility along the belt circumference
provides good support to High Modulus - Low Stretch (HMLS)
tension member and thereby enhancing the power rating of the
belt by 20% to 30% compared to the corresponding section of
a standard V-Belt.
With the High Power Belts, the number of belts in a matched
set of a multiple-belt-drive gets reduced and the belt life
is also improved significantly. The HMLS tension member
minimises the belt stretch, improving the machine-up time. |

Armid Cord Belts Belts |
|
|
Aramid is an
organic polyaramide fibre that is manufactured using complex
chemical processes. It is generally used where the power
transmission requirements are very critical, apart from
space restrictions on the permissible installation and take
up allowances. Aramid is used as tension member because of
its high tensile strength.
Aramid Cord Belts
are recommended where,
•
There are restrictions on the drive width
• The installation & take-up allowances are minimal
• Critical drives
