Spur gear module 3 z=39 with hub

Product Description

Spur gear module 3, z=39, with hub

This module 3 spur gear (39 teeth, with hub) is used wherever reliable, maintenance-free power transmission via involute gearing is required. The base material is C45E structural steel (EN 10083-1) - a proven choice for gear transmission components used in Polish industry.

Technical data

Frequently asked questions

How does the build quality of a Polish/European manufacturer reduce rolling resistance in the gearbox?

Cheap gears from unverified sources often have a rough tooth surface that acts like sandpaper, raising the temperature and the drive resistance. Our gears have a smooth working surface, which helps maintain the lubricating film and minimises energy losses.

How do you set the correct centre distance between two module gears?

The centre distance is the sum of the pitch diameters of both gears divided by two (a = (Dp1+Dp2)/2); too small a distance causes seizing, and too large a distance - excessive backlash and loss of quiet running.

How do you choose the gear material (C45E steel, stainless steel or plastic) for specific operating conditions?

C45E steel is a universal choice for most industrial drives, stainless steel performs well in humid or aggressive environments, and plastics are used for lower loads or when quiet running and lubrication-free operation matter.

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).

Where is this product used?

Module gears of this type are used in speed reducers, machine gearboxes, CNC machine tools and in rack drives of sliding and entrance gates.

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.
