Spur gear module 1.5 z=46 with hub

Product Description

Spur gear module 1.5, z=46, with hub

The spur gear module 1.5 with z=46 teeth (with hub) is a universal modular component whose parameters match the entire family of gears and gear racks of the same module. The base material is C45E structural steel (EN 10083-1) - a proven choice for gear transmission parts operating in European industry.

Technical data

Frequently asked questions

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 measure a worn tooth to choose the right replacement?

It is best to measure the outside diameter (Dz) and count the teeth (Z), and calculate the module from the formula m = Dz / (Z+2); it is also worth measuring the bore diameter so that the replacement fits the same shaft without additional machining.

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.

Does a higher number of teeth (z) with the same module mean a stronger gear?

Not directly - tooth strength depends mainly on the module and face width, not on the number of teeth; a larger z with the same module simply gives a larger gear diameter and a higher ratio relative to the mating gear.

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.

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.
