The main difference between a Starter Motor Drive Bendix and an ordinary starter motor drive lies in their design and functionality.
A Starter Motor Drive Bendix is a type of starter motor drive that incorporates a mechanism called a Bendix drive. The Bendix drive is a gear mechanism that engages with the engine's flywheel or flexplate to transfer rotational motion and start the engine. It consists of a helical gear, which is driven by the starter motor, and a set of spring-loaded clutch teeth. When the starter motor is activated, the helical gear rotates and pushes the clutch teeth forward, allowing them to engage with the flywheel or flexplate. This engagement transfers the rotational force from the starter motor to the engine, starting the combustion process.
An ordinary starter motor drive typically uses a direct engagement mechanism. It consists of a pinion gear that meshes directly with the flywheel or flexplate teeth. When the starter motor is activated, the pinion gear engages with the teeth, transferring rotational motion to the engine and initiating the starting process.
The key advantage of a Starter Motor Drive Bendix is that it provides a smoother and more gradual engagement with the flywheel or flexplate. This helps to reduce wear and tear on the teeth and minimizes the chances of damage during the starting process. In contrast, an ordinary starter motor drive can sometimes cause a harsher engagement, which may lead to premature wear of the teeth or potential damage.
The choice between a Starter Motor Drive Bendix and an ordinary starter motor drive depends on the specific application, engine design, and manufacturer's recommendations. Both types of drives serve the same purpose of starting the engine, but the Bendix drive offers certain advantages in terms of smoother engagement and potentially increased longevity.
