Spur gear module 2 z=75 plate wheel

Product Description

Spur gear module 2, z=75, plate wheel

Gear module 2, z=75, plate wheel - a robust component for building and repairing gear transmissions, gear reducers and rack drives (rack + gear). The standard material is C45E steel (UNI EN 10083-1), widely used in the construction of gear transmissions, gear racks and module drives.

Frequently asked questions

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.

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 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).

How can you recognise a manufacturing defect in a gear when receiving the goods?

It is worth checking the radial runout (the gear should not "wobble" on the shaft), the uniformity of the pitch between teeth and the smoothness of the tooth surface - visible burrs, dents or uneven pitch are a signal to file a complaint.

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.
