Spur gear module 3 z=20 with hub

Product Description

Spur gear module 3, z=20, with hub

Gear module 3, z=20, with hub - a robust component for building and repairing gear transmissions, reducers and rack drives (gear rack + gear). Made of C45E steel (UNI/EN 10083-1), which ensures high mechanical strength and wear resistance during prolonged operation under load.

Technical data

Frequently asked questions

How do you choose a gear rack to match a specific module gear?

The principle is the same as when selecting two gears - the rack must have the same module as the drive gear. Remember to choose the right rack width, which should be equal to or slightly wider than the face width of the gear, in order to transmit the full torque.

Why is precise machining of module gears crucial for drive service life?

A precisely cut tooth involute guarantees that the gears roll on each other without micro-impacts or slippage. This reduces friction lowers the operating temperature and dramatically extends the service life of the entire gearbox.

What does the pressure angle mean in module gears and why is it usually 20°?

The pressure angle defines the inclination of the tooth flank. In European industry the standard is 20°, because it provides the optimal balance between tooth root strength and quiet gearbox operation. This avoids the phenomenon known as tooth undercutting on smaller gears.

How do you cut a keyway in a module gear with a small hub?

In gears with a small hub, the keyway is slotted with great care so as not to weaken the wall above the tooth. If there is not enough space, we recommend dispensing with a standard key (feather key) in favour of mounting with clamping bushes (locking assemblies).

Where is this product used?

Typical applications include conveyor drives, packaging machines, industrial automation and positioning systems using a gear and gear rack pair.
