Frequently asked questions
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.
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.
Does the tooth shape of a module gear affect smooth running?
Yes, the ideal involute profile achieved through precise machining ensures uniform power transmission. This prevents jerking that could lead to teeth breaking off under load.
How do you cut a keyway in a module gear with a small hub?
In gears with a small hub, the keyway is slotted with great care so as not to weaken the wall above the tooth. If there is not enough space, we recommend dispensing with a standard key (feather key) in favour of mounting with clamping bushes (locking assemblies).
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.
