Worm Wheel Sets  Manufacturers, Traders, Suppliers

universally applicable for backlash-free transmission of rotary movements, strongly vibration damping, good compensation of misalignments, low torsional spring stiffness, small restoring forces, no moving parts, very robust design

• A worm gear consists of a worm screw and a worm wheel. It is for perpendicular power transmission by simultaneous height offset. As a rule, the driving element is the worm screw. So that wheel/worm can be combined to a worm gear, an equal centre distance and equal transmission ratio must be assured. The centre distances are available ex stock in small steps between 17 mm and 80 mm. Several transmission ratios are available per centre distance.
• norelem worm gears are suitable for producing worm drives with an axis angle of 90°. With worm drives, very large speed reducing ratios (up to 100:1) are realisable.
  Other advantages:
  
• - Quiet running
  - Low vibration

Steel worm screws

The right hand, case-hardened steel worm screws have ground flanks and bores. The teeth have the flank form K. The worm gear is also finish bored.

Worm wheels

The product range from norelem only includes bronze worm wheels. The reason for this is simple, bronze guarantees the best glide and dry-running properties compared to other materials. The aluminium content also assures high chemical resistance. Worm wheels are highly suitable for continuous operation with high speeds and high torques.

Material:Worm screw steel.
Worm wheel CuZn37Mn3Al2PbSi-S40.Version:Worm screw with right-hand pitch, case-hardened HV 620 – 700, flanks and hole ground.Note for ordering:Wheels/screws can only be combined to form a worm gear if they have the same centre distance and transmission ratio.Note:A worm gear consists of a worm screw (shaft) and a worm wheel. Suitable for forming worm drives with a 90° shaft angle. A worm drive enables very large speed reduction ratios with a single stage.
The toothing has the flank shape K. The engagement angle is 15°. The worm gears are pre-bored.
The stated T2 output torques are the permissible output torques on the worm wheel. These apply for an input speed of 2800 rpm of the worm screw.
The worm gears are suitable for continuous operation at high speeds and high torques.
