Technodrive hydraulic reverse gear TM93 2.40:1

Description

Technodrive hydraulic reverse gear TM93 R=2.40:1

The Technodrive TM93 is a hydraulically operated reverse gear for inboard drives in marine installations. This version has a reduction ratio of 2.40:1 in both forward and reverse. The reverse gear is used to transfer engine power to the propeller shaft in a controlled way and enables shifting between forward, neutral and reverse.

Thanks to its hydraulic operation, the TM93 is designed for smooth shifting and reliable operation under load. This version is suitable for installations where a higher reduction ratio is required. Always check that the reduction ratio, maximum permitted torque, installation dimensions and connection match the existing engine and propeller shaft installation.

Application

This Technodrive reverse gear is used in inboard drive systems where the engine drives the propeller shaft via a reverse gear. The transmission provides the correct reduction of engine speed and makes it possible to change the rotation direction of the propeller shaft. This makes the reverse gear an important component for the propulsion and manoeuvrability of the boat.

Main features

• Hydraulic operation: Ensures smooth shifting and reliable power transmission.
• Forward reduction 2.40:1: Suitable for installations where this gear ratio is required.
• Reverse reduction 2.40:1: Equal reduction in both sailing directions.
• Maximum input speed 4,500 rpm: For compatible engine installations within this speed limit.
• Oil capacity 2 litres: Supports lubrication and cooling of the internal components.
• Lubrication pressure 0.5-1.5 bar: For reliable lubrication of the reverse gear.
• Operating pressure 24 bar: Designed for hydraulic operation under load.
• Dry weight 51 kg: Robust design for marine drive systems.

Why the correct reverse gear is important

A reverse gear is an essential component of the driveline. An incorrectly selected, worn or poorly fitting reverse gear can cause slipping, poor shifting, vibrations, heat build-up or damage to the engine, coupling and propeller shaft installation. It is therefore important to carefully check the specifications of the existing installation before replacing the reverse gear.
