Maximum Speed Setting adjusts input shaft wheels close together to form a large driving diameter. This automatically separates output shaft wheels to form a small driven diameter. Manimum Speed Setting adjusts input shaft wheels wide apart to form a small driving diameter. This automatically closes output shaft wheels to form a large driven diameter.

Maximum Speed Setting adjusts input shaft wheels close together to form a large driving diameter. This automatically separates output shaft wheels to form a small driven diameter. Manimum Speed Setting adjusts input shaft wheels wide apart to form a small driving diameter. This automatically closes output shaft wheels to form a large driven diameter. Here is the P. The sprockets of the PolY chain drive are two pairs of the cone - shaped radially - grooved wheels mounted on splined shafts.
The chain is made from unique links which contain packes of self - tooth - forming hardened steel slats. Each slat is free to move sidewise and conform to the tooth shape of the paired sprockets. When the paired wheels are far apart the chain actually operates around a small diameter. When the wheels are close together the chain operates around a large diameter. This principle - varying the driving and driven diameters - is the principle on which all variable speed drives operate.
Only the P.!. This makes the P. Long dependable life - Proper design and care ful manufacture of parts, broad use of many alloy steels heat-treated for maximum strength and wear resistance, and automatic lubrication from a common reservoir, insure long life as attested by many P.
Low maintenance requirements - Maintenanace is limited to maintaining correct chain tension and oil level. An infinite number of speeds between m.
The Posired 2 range has great flexibility and torque ratings to over two million Nm. PIV drives enjoy an outstanding reputation for quality Power-transmission solutions. Read More Helical to , Nm Hoisting machinery with drum and motor in parallel requires gearboxes with extended center distance between the input and output shaft. POSIRED N series gearboxes were designed for this application and perfectly solve the problem of the distance between the motor and drum. Widespread experience in crane engineering for main hoist, boom Complete range of modular design planetary gearboxes for industrial applications. It combines high performance with compact size, excellent reliability, simple installation and reduced maintenance.
NET are able to supply and service all types of P. Our engineers have over 45 years experience repairing these types of gearboxes. V Stands for Positively Infinitely Variable. The simple and efficient PIV variator is a good alternative to an electric drive: from machine tools to paper production lines, from packaging machines to pump drives. They may, however, be present on virtually any equipment requiring an adjustable speed output or straight gear reduction. Due to the negligible power losses the variator performs with very high efficiency, even when running under partial load.
