- 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
Range:
We manufacture the entire range of
Classical V-belts. The nominal
length designation for these belts
is inside length (Li) in inches. The
length conversion factors are
mentioned in the specification sheet
below.

- 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: -180C to +800C
● 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

Features:

Temperature Range: -180C to +800C
● Maximum recommended belt speed is 30 m/s*
