Spur gear module 1 z=33 with hub

Product Description

Spur gear module 1, z=33, with hub

This module 1 spur gear (33 teeth, with hub) is used wherever reliable, maintenance-free power transmission via involute gearing is required. The standard material is C45E steel (UNI EN 10083-1), widely used in the construction of gear transmissions, gear racks and module drives.

Technical data

Frequently asked questions

What lubrication is optimal for open module (rack) gear drives?

For open systems (gear + gear rack), it is best to use thick greases with added graphite or copper, which adhere firmly to the teeth and are not flung off by centrifugal force. In very dusty applications, dry Teflon lubricants perform better.

Can gears with different modules be combined in one gearbox?

Absolutely not. Teeth of different modules differ in size and pitch. Any attempt to mesh them will end in the drive jamming or the teeth breaking off immediately on the first revolution of the shaft.

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.

Does a module gear require constant lubrication?

Enclosed gears (in speed reducers) run in oil or grease, while open systems (gear + rack) require periodic manual lubrication - without it, friction and tooth wear increase many times faster.

Where is this product used?

It performs well in power transmission systems in machine tools, production lines and sliding gates, where it works together with a gear rack of the same module.

When placing your order, please check the current stock level of this gear - the lead time depends on it and is clearly stated according to the quantity available in the given warehouse.
