34t Crown Gear. Anglewinder

Precision in Transmission with Slot.it's 34-Tooth Anglewinder Crown Gear

The SIGA1834E crown gear from Slot.it is a key component in any anglewinder setup looking to optimise the gear ratio without adding unnecessary weight. With 34 teeth, a diameter of 18 mm, and made from ergal (high-strength aluminium alloy), this crown gear combines robustness and lightness in a single piece.

Main Features

• Number of teeth: 34
• Diameter: 18 mm
• Material: Ergal (aluminium alloy)
• Lightweight design: reduces rotating mass and improves overall response
• Configuration: Anglewinder
• Reference: SIGA1834E
• Manufacturer: Slot.it

Function and Performance

In an anglewinder configuration, the motor is positioned at an angle to the rear axle, which requires a crown gear specifically designed for that attack angle. The SIGA1834E is machined to engage smoothly in this type of setup, ensuring constant contact with the pinion and minimising vibrations and energy losses in the transmission.

The use of ergal is not coincidental: this material offers a much higher strength-to-weight ratio than plastic, withstands prolonged working temperatures well, and maintains its geometry under load, which is essential when seeking consistency lap after lap in long race sessions.

The lightweight design reduces rotational inertia, resulting in a more responsive throttle when accelerating and more precise braking. This advantage is noticeable on short distances and circuits with many chicanes.

Compatibility and Installation

This crown gear is designed for Slot.it's anglewinder transmission systems. It is compatible with the chassis and motor groups of the brand that utilise this configuration. To choose the correct gear ratio, combine it with the appropriate pinion according to the motor and circuit layout: more teeth on the crown gear implies greater torque and lower top speed, which can favour technical circuits with slow corners.

Installation does not require special tools beyond a crown gear puller and an axle adjustment wrench. It is recommended to check the backlash (play between pinion and crown gear) before each session to ensure optimal engagement.

Ideal for…

This reference is particularly interesting for:

• Preparers looking to reduce weight in the transmission without sacrificing durability.
• Club competitors wanting to adjust the gear ratio to suit different layouts.
• Enthusiasts building or tuning Slot.it anglewinder chassis who need original brand replacement parts.

Frequently Asked Questions

What is the difference between an ergal crown gear and a plastic one?

Ergal is an aluminium alloy that offers much greater mechanical and dimensional strength than plastic. It withstands the heat generated in long sessions better and maintains its shape under load, resulting in more consistent engagement and greater durability in competitive conditions.

Is this crown gear compatible with any anglewinder chassis?

It is designed for Slot.it's anglewinder systems. Compatibility with chassis from other brands depends on the pitch of the teeth and the diameter of the axle. Always check your chassis specifications before combining components from different manufacturers.

What gear ratio do I get with 34 teeth?

The gear ratio depends on the pinion you combine with this crown gear. A higher number of teeth on the crown gear relative to the pinion results in greater torque multiplication and lower top speed. A value of 34 teeth is a mid-high option, suitable for technical circuits or for gaining traction on acceleration.

Does the lightweight design affect the strength of the crown gear?

Not significantly under normal usage conditions. The material reliefs are calculated to maintain the structural integrity of the teeth and the body of the crown gear. In recreational or club use, the durability is more than sufficient.

Can I use this crown gear on Sport track?

This crown gear is an internal transmission component of the car and does not directly depend on the type of track. What matters is that it is compatible with your motor group and anglewinder chassis. The Sport track (compatible with Scaleauto and Slot.it tracks, among others) does not condition the choice of crown gear.

The Slot.it SIGA1834E is a 34-tooth anglewinder crown gear machined in ergal aluminium, measuring 18 mm in diameter. Its lightweight design reduces rotational inertia, improving throttle response and braking precision. A go-to replacement part for slot car builders and club racers looking to fine-tune transmission ratios on Slot.it anglewinder setups.
