The review said: "Robertson's take on Lego's success holds plenty of lessons for companies pondering how to remain innovative in a fast-changing world. With new lines such as Ninjago , products such as board games, and open innovation through fan-designed sets via its Cuusoo platform, Lego is showing how far you can take one simple yet ...
Spiral bevel gear. A spiral bevel gear is a bevel gear with helical teeth. The main application of this is in a vehicle differential, where the direction of drive from the drive shaft must be turned 90 degrees to drive the wheels. The helical design produces less vibration and noise than conventional straight-cut or spur-cut gear with straight ...
Lego Technic / ˈ t ɛ k n ɪ k / (stylized as LEGO Technic) is a line of Lego interconnecting plastic rods and parts. The purpose of this series is to create advanced models of working vehicles and machines, compared to the simpler brick -building properties of normal Lego.
Differential operation while driving in a straight line: Input torque is applied to the ring gear (purple), which rotates the carrier (purple) at the same speed. When the resistance from both wheels is the same, the planet gear (green) doesn't rotate on its axis (although the gear and its pin are orbiting due to being attached to the carrier).
A limited-slip differential (LSD) is a type of differential gear train that allows its two output shafts to rotate at different speeds but limits the maximum difference between the two shafts. Limited-slip differentials are often known by the generic trademark Positraction , a brand name owned by General Motors and originally used for its ...
A Lego theme is a product line of Lego construction toys produced by The Lego Group based on a central concept.. Before 1978, Lego produced several construction sets with common themes, but they were not necessarily branded as part of a single series or theme.
Hypoid gear sets have long been used in the differential of rear-wheel drive cars, trucks and robotic arms.The scope of misalignment between the centers of the two interlinking shafts permits utilization of larger sized gears which enhances the contact surface area and reduces the wear and tear on the gear hence extending the life and power transmission capabilities of the gearboxes.
The pitch surface of an ordinary gear is the shape of a cylinder. The pitch angle of a gear is the angle between the face of the pitch surface and the axis. The most familiar kinds of bevel gears have pitch angles of less than 90 degrees and therefore are cone-shaped. This type of bevel gear is called external because the gear teeth point ...
