Aluminium angular crown gear 32 teeth 17.5mm for Ninco

NSR6232 Angle Crown Gear: Aluminium, 32 Teeth and Direct Compatibility with Ninco Anglewinder

The NSR6232 is a precision-machined aluminium angle crown gear designed for those who mount their Ninco cars in anglewinder configuration. With 32 teeth, 17.5 mm diameter, and a 20° angle, it meets the needs of tuners seeking precision in transmission without adding unnecessary weight to the rear end.

Technical Features

• Material: precision-machined aluminium
• Number of Teeth: 32
• Diameter: 17.5 mm
• Angle: 20° (anglewinder)
• Tooth Profile: reverse (Reverse Teeth), specific for anglewinder mounts in Ninco
• Recommended Pinion: Ø 6.75 mm
• Reference: NSR6232

Function and Performance

The reverse tooth profile of this crown gear is the key detail: in an anglewinder configuration, the motor's direction of rotation requires the teeth to be oriented opposite to those of a standard crown gear. NSR has addressed this with a specific geometry for Ninco that ensures correct meshing, without play or vibrations that would hinder acceleration response.

Aluminium, in addition to reducing rotating mass compared to plastic or brass crowns, offers rigidity that keeps the gear ratio stable even on high-speed tracks. Less inertia in the rear end translates directly to better trigger response and more effective braking.

Compatibility

This crown gear is designed for Ninco cars with anglewinder (AW) mount. To ensure correct meshing, NSR recommends pairing it with a pinion of Ø 6.75 mm. Before mounting, check that the wheelbase of your chassis allows for this combination without forcing the meshing.

Mounting and Preparation

The mounting process is straightforward, but there are some points to consider:

• Verify that the rear axle and crown holder of the Ninco chassis are compatible with the diameter and fastening system of this NSR crown gear.
• Adjust the distance between the crown gear and pinion to achieve minimal play without tightness: the drivetrain should turn freely but without lateral wobble.
• Apply a minimal amount of specific gear lubricant to the teeth after adjustment.
• Check the meshing after the first laps to confirm that no play has developed.

Common Errors

• Confusing standard crown gear with reverse tooth crown gear: mounting a standard tooth crown gear on a Ninco anglewinder results in incorrect meshing and premature wear.
• Choosing a pinion outside the recommended range: deviating from Ø 6.75 mm may result in vibrations or a drivetrain that does not transmit power effectively.
• Over-tightening the fastening: this can deform the aluminium or create friction during rotation.

Frequently Asked Questions

Is this crown gear suitable for any anglewinder configuration or just for Ninco?

NSR has specifically designed it for anglewinder on Ninco chassis (Ninco AW). The reverse tooth profile and dimensions are tailored for that system. For other anglewinder chassis, it is advisable to check compatibility before mounting.

What pinion should I use with the NSR6232?

NSR recommends a pinion of Ø 6.75 mm. Adhere to this diameter to ensure clean meshing and optimal transmission performance.

What advantage does an aluminium crown gear have over a plastic one?

Precision-machined aluminium offers greater dimensional rigidity and less wear over time. Additionally, being lighter than brass, it reduces rotating mass in the rear end, improving throttle response and braking.

What is reverse tooth profile (Reverse Teeth)?

In an anglewinder configuration, the motor rotates in the opposite direction to that of an inline or sidewinder mount. For correct meshing, the teeth of the crown gear must be oriented in reverse. The NSR6232 incorporates this specific tooth profile.

Is it compatible with Ninco track or universal rail?

The crown gear's compatibility is with the car Ninco, not with the type of track. Ninco uses universal rail, just like Scalextric, so the car prepared with this crown can run on any universal rail track.

The NSR6232 is a precision-machined aluminium angle crown gear with 32 teeth and 17.5 mm diameter, featuring reverse teeth at 20° for correct meshing in Ninco AW slot car setups. Recommended pinion size is Ø 6.75 mm. Lightweight aluminium construction reduces rotational mass for improved throttle response and braking performance on any universal rail track.
