Y Series Top-Entry Tank Agitator
The ProQuip Y Series Top-Entry Tank Agitator has a right angle power package configuration for mounting in minimum headroom situations and easy service access. The gears are enclosed in a rugged, oil-tight, cast-iron housing for strength and dependability as well as resistance to chemical attack from most corrosive fumes. The case is designed with a “dry-well” to prevent oil leakage.
- Rugged cast iron housing resists shock loads, maintains accurate gear alignment
- Rugged design with double reduction. First stage helical gears and second stage involute helicoid thread form worm gearing
- Strength and power of worm gear plus the efficiency of helical or spiral bevel gear
- Oversized output shaft and heavy-duty tapered roller bearings with L-10 lives in excess of 100,000 hours
- Dry-well dam around output shaft provides a positive barrier against oil leakage
- NEMA motors flexibly coupled to the gearbox
Design Features
AReduction
Double reduction gearing provides output speeds down to 1 RPM, thus having substantially fewer parts than triple-and quadruple-reductions required in helical or spiral bevel units to reach comparable output speeds.
BFirst Stage
The first stage of reduction uses hardened, shaved precision helical gears, most suitable for quiet, long-lasting operation at motor speeds.
CSecond Stage
The second stage reduction uses worm gearing having an involute helicoids thread form. This thread form ensures proper, close contact for higher capacity and longer life than other worm gears, yet achieves high efficiency without the necessity of lapping and running-in required for other worm gears.
DGear Mechanism
The worm is machined from alloy steel and is hardened, ground and polished, providing a hard wear-resistant surface over a tough shock-resistant core.
EBearings
The worm is carried in roller bearings maintaining precise alignment and providing long, dependable service. The gear is mounted on the substantially oversized output shaft, which allows large diameter overhung shafts to be used.
FLubrication
The Power Packages are designed so that they can be left unattended with confidence between normal routine maintenance and inspection checks.
