Transmissions: Light Duty

The Eaton® Light Duty Hydrostatic Transmission Models 6, 7 and 11

The Eaton® Light Duty Hydrostatic Transmission consists of a variable displacement radial ball piston hydraulic pump, a fixed displacement radial ball piston hydraulic motor and a system of valves, all contained in one housing. It can be used in many different types of applications where variable output speed is a requirement. It has many advantages over other variable speed drives (electric and mechanical) and gear type transmissions.

Typical applications include Lawn Tractors, Concrete saws, Agricultural Sprinklers.

Features

• Ball Piston design less sensitive to over heating
• Totally integrated pump/motor package
• Aluminum cooling fins
• Precise single lever control

Benefits

• Proven, reliable
• Eliminates leaks from external lines
• Environment/temperature tolerant
• Can in some case eliminate need for external cooler
• Eliminates complex linkages

• Response - These transmissions respond faster than any other type of power-transmitting system.
• Precise speed - Has the capability of maintaining precise speed under varying load conditions.
• Ease of operation - One lever controls direction and speed smoothly without gear change.
• Low maintenance - Simple design keeps maintenance to a minimum.
• Increased Productivity and Versatility - It allows complete matching of power to load.
• Self contained - There are no external high pressure lines, separate drive components, etc.
• Simplified final product design - It reduces the number of mechanical drive components.
• Positive Braking Action - The lever that controls speed also provides braking. The output shaft speed decreases as lever is moved toward neutral. With lever in neutral, output stops.
• The Model 6 transmission is designed primarily for light duty applications requiring up to 1,9 kW [2.5 hp] output for continuous operation.
• The Model 7 transmission is an expansion of the light duty product line. The Transmission is a result of product refinements to the Model 6 Transmission. Most significant among these refinements is reduction in noise levels generated by various duty cycle situations at high torque or load conditions.
• The Model 11 transmission is designed primarily for applications with engines rated at 7,5- 15 kW [10-20 hp] at maximum speed of 3600 rpm, or electric motors up to 7,5 kW [1 hp] at 3600 rpm.
