What is the function of Bendix drive?
What is the function of Bendix drive?
A Bendix drive is a type of engagement mechanism used in starter motors of internal combustion engines. The device allows the pinion gear of the starter motor to engage or disengage the flywheel of the engine automatically, when the starter is powered or when the engine fires, respectively.
What are the advantages of Bendix drive?
Inertial pinion type of Bendix drives offer several benefits. Their operation is entirely mechanical, which makes them easy to maintain or troubleshoot. They are also less of a challenge to troubleshoot when faulty. When used with gear reduction mechanisms, these drive types use little power to start an engine.
What are the two types of Bendix drives?
Explanation: Inboard and outboard are the two types of Bendix drives. In the outboard type pinion moves away from the starting motor to engage the flywheel whereas in the inboard type it moves towards the starting motor.
What causes Bendix drive failure?
The main drawback to the Bendix drive is that it relies on a certain amount of “clash” between the teeth of the pinion and the ring gears before they slip into place and mate completely; the teeth of the pinion are already spinning when they come into contact with the static ring gear, and unless they happen to align …
How do you lube a Bendix?
After the Bendix Drive has been thoroughly cleaned and blown dry with compressed air, lubricate the screwshaft threads and ratchet with a silicone spray. Lubricate the motor shaft with the same silicone lubricant before installing the drive assembly on the shaft.
What’s a starter Bendix?
The device allows the pinion gear of the starter motor to engage or disengage the ring gear (which is attached to the flywheel or flexplate of the engine) automatically when the starter is powered or when the engine fires, respectively. It is named after its inventor, Vincent Hugo Bendix.
What’s Bendix?
A Bendix drive is a type of engagement mechanism used in starter motors of internal combustion engines.
How do you clean a Bendix starter?
Use only clean petroleum base cleaners such as kerosene or varsol. Thoroughly clean the Bendix Drive to remove all dirt and contamination from the screwshaft threads and control nut. If the drive is exceptionally dirty, the drive pinion cup can be removed to ensure a thorough cleaning job.
How do I replace a Bendix Drive?
Replacing the Bendix on a pre-engaged starter motor
- Use a pulling tool to remove the thrust collar.
- Tap this type of collar down with a piece of piping used as a drift.
- Remove the jump ring with a screwdriver.
- A purpose-made Bendix spring compressor can be used to free the circlip.
How do I clean my Bendix Drive?
Clean the area in front of the Bendix Drive pinion before removing the drive from the shaft. Do not use carburetor cleaner or any solvents that could damage the rubber block inside the Bendix Drive. Use only clean petroleum base cleaners such as kerosene or varsol.
What is the starter Bendix?
The Bendix system places the starter drive pinion on a helical drive spring. When the starter motor begins turning, the inertia of the drive pinion assembly causes it to wind the spring forcing the length of the spring to change, and allowing the pinion to engage with the ring gear.
What is a Bendix drive used for?
Bendix drive. A Bendix drive is a type of engagement mechanism used in starter motors of internal combustion engines.
What is a Bendix drive starter motor?
A Bendix drive is a type of engagement mechanism used in starter motors of internal combustion engines. The device allows the pinion gear of the starter motor to engage or disengage the flywheel of the engine automatically when the starter is powered or when the engine fires, respectively.
What is a pre-engaged Bendix drive?
The pre-engaged Bendix drive uses a solenoid to push and retract the pinion drive gear. The solenoid is usually fixed on the top of the starter motor, moving the pinion via a fork-shaped lever. The drive’s operation is thus electrically operated, compared to the automatic action of the inertial pinion type of drive.
How does a Bendix pinion drive gear work?
The springs help to control the pinion’s movements as well as absorb their shock. The pre-engaged Bendix drive uses a solenoid to push and retract the pinion drive gear. The solenoid is usually fixed on the top of the starter motor, moving the pinion via a fork-shaped lever.
