Spur gear module 3 z=15 with hub

Product Description

Spur gear module 3, z=15, with hub

The spur gear module 3 shown, 15 teeth, with hub, is a basic component of module drives - it meshes with any other gear or gear rack (toothed rack) of the same module and pressure angle 20°. 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

In which applications do helical module gears perform well?

Helical teeth ensure smoother engagement, which drastically reduces noise and vibration at high rotational speeds. They are used in precision speed reducers and machine tools, bearing in mind, however, the need to use thrust bearings (absorbing axial forces).

How do you calculate the ratio of a gear pair of two module gears with different numbers of teeth?

The ratio is calculated as the quotient of the number of teeth of the driven gear to that of the driving gear (i = Z2/Z1); the module must be identical for both gears, otherwise meshing will not work at all.

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).

Are the gear wheels for sliding gates also module gears?

Yes, the classic gate drive gear is a module gear working with a gear rack fixed to the gate leaf. This is usually module 4 (m=4), and for intensive commercial use precision-machined components are chosen that run quietly and without jamming.

Where is this product used?

Used in the construction and servicing of gear reducers and gear transmissions for agricultural and construction machinery, and wherever precise and repeatable torque transmission matters.
