Spur gear module 1 z=72 with hub

Product Description

Spur gear module 1, z=72, with hub

The module 1 spur gear z=72 with hub is a precision gear transmission component designed to transmit high torques at a constant ratio. The base material is C45E structural steel (EN 10083-1) - a proven choice for gear transmission components used in Polish industry.

Frequently asked questions

What is the module of a gear and how do you measure it correctly?

The module (m) is the basic parameter defining tooth size, i.e. the ratio of the pitch diameter to the number of teeth. The simplest way to measure it in workshop conditions is to measure the outside diameter of the gear (Dz), count the teeth (Z) and use the formula: m = Dz / (Z + 2).

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.

What is the difference between a gear with hub (PM) and a plate wheel (CM), and when should you choose which?

The hub extends the part axially and makes mounting on the shaft easier (more room for a key or a clamping ring), while the plate wheel is flat and lighter - it is chosen when the design already has its own bearing arrangement/mounting and the gear only has to transmit the meshing.

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.

Where is this product used?

Used in industrial machine drives, gate and industrial door automation and as a spare part for existing module gear drives - you only need to keep the same module and pressure angle.

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.
