Spur gear module 4 z=65 with hub

Product Description

Spur gear module 4, z=65, with hub

Gear module 4, z=65, with hub - a robust component for building and repairing gear transmissions, reducers and rack drives (gear rack + gear). The gear is made of C45E steel (EN 10083-1); the involute tooth profile and 20° pressure angle ensure smooth, quiet meshing with gears or racks of the same module.

Technical data

Frequently asked questions

Can module gears be bored out for non-standard shafts?

Yes, most module gears are supplied with a pilot bore, which allows them to be freely bored out, keyway-slotted and precisely fitted to the specific shaft size at the customer's premises.

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).

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 lubrication is optimal for open module (rack) gear drives?

For open systems (gear + gear rack), it is best to use thick greases with added graphite or copper, which adhere firmly to the teeth and are not flung off by centrifugal force. In very dusty applications, dry Teflon lubricants perform better.

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.
