Product catalog summary

Introduction
The document provides an overview of variable speed pulleys and motor slide bases, emphasizing their simplicity and cost-effectiveness for adjusting shaft rotation speeds without halting transmission. Key advantages include reliability, a broad selection, ease of installation, precision, competitive pricing, and certified Italian quality.

Main Product Range

Variable Centre Distance: Utilizes two plates sliding symmetrically on a hub, allowing speed variation up to a 1:3.5 ratio by adjusting the distance between pulleys.
Fixed Centre Distance: Consists of a pair of pulleys with a single mobile disc, enabling speed variation up to a 1:12.3 ratio via a handwheel on the driving pulley.

Technical Specifications
Details on various models include:

VAR.D.E.A.C. / MTZ: Helical springs, galvanized plates, self-lubricating hub, max ratio 1:3.4, max power 18.5 Kw.
VAR.D.E.A.C. / MTE: Helical springs, phosphated plates, max ratio 1:3.5, max power 4 Kw.
VAR.D.E.A.C. / TE / IF: Mono-expandable, max ratio 1:12.3, max power 18.5 Kw.
VAR.D.E.A.C. / COMPACT: Mono-expandable, max ratio 1:2.5, max power 1.5 Kw.

Transmission Dimensioning
Guidelines for proper pulley functioning include:

Identifying engine shaft speed and necessary variation ratio.
Selecting the appropriate pulley family based on application needs.
Establishing the torque to be transmitted.
Ensuring peripheral belt speed is between 4 and 30 m/s.

Warnings and Recommendations
For optimal use and longevity:

Speed variation should occur with the machine in motion.
Avoid damaging pulley surfaces with tools.
Use timing belts specifically designed for variators.

Application Examples
Examples illustrate the use of expandable-disc driving pulleys and fixed driven pulleys, emphasizing speed variation through motor slide bases.

Technical Details
Includes dimensions, power specifications, and notes on maintenance-free, self-lubricating hubs, and suitability for high power and dusty environments.

Specifications
The document provides detailed specifications for mechanical components, including mono-expandable pulleys with fixed distance between centers. It includes dimensions, power ratings, belt sections, and transmission ratios for different pulley sizes, highlighting materials like die-cast iron and galvanized sheet steel.

Procedures
Outlines procedures for assembling and adjusting pulleys, emphasizing specific assembly schemes (U or Z assembly) and speed adjustment using a handwheel or hydraulic/pneumatic systems while the machine is running.

Standards and Recommendations
Recommendations ensure correct use and longevity of pulleys, such as maintaining a peripheral speed between 4 and 30 m/s and using timing belts designed for variators.

Warnings
Warnings stress the importance of correct assembly and operation to prevent damage and ensure optimal performance.

Application Examples
Examples demonstrate how speed variation is achieved using specified systems, highlighting the importance of performing speed variations exclusively when the machine is in motion.
