Spur gear module 4 z=17 with hub hardened

Product Description

Spur gear module 4, z=17, with hub, hardened

Gear module 4, z=17, with hub - a robust component for building and repairing gear transmissions, reducers and rack drives (gear rack + gear). The tooth surface is induction hardened (45-55 HRC), so the gear better withstands high cyclic loads and operation in harsh industrial conditions.

Technical data

Frequently asked questions

Can I buy ready-made modules with drilled mounting holes at ozdowski.pl?

As standard, we supply gears and racks with a smaller pilot bore, which gives you complete freedom in adapting them to your design. You can drill the holes yourself, tap them for set screws, or send us the parameters so that our CNC department can carry out the finished modifications.

How do you mount a module gear using clamping rings?

These rings are slid between the plain shaft and the plain bore of the gear. When the screws are tightened, the ring expands and locks the gear with a force many times greater than a traditional key. This is the ideal solution for module gears operating with changing direction of rotation (no backlash at the key).

Do straight-tooth module gears have a specific mounting direction?

No, a straight-tooth gear is symmetrical and can be mounted either way round; direction only matters with helical teeth, where the helix angle must match the mating gear.

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?

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.
