GEARBOX is delivered with:

  • Gearbox with big pulley and helical pinion (HTD pulley 90 teeth )
  • HTD 550-5M Timing Belt
  • HTD 5M mini pulley for motor / mounting hole ø14mm (18 teeth)
  The racks cannot be cut, they are sold piece by piece. Each piece is 960mm long. The rack bars are finely milled and grind on the outside. Pressure angle 20° and tooth angle 19°31’42” Opposite Tooth Gauge short rack is used for assembly of Helical toothed racks. For the helical design, we offer companion racks, which are toothed in the opposite direction. In this case, you will always have stable and precise continuity at the joints of two racks and speed up the assembly time.

 Helical vs Spur Gears


  • Due to its progressive contact, process performance is smoother and producesless noise. Dynamical loads are also reduced.
  • This type of gears can work at higher speeds than spur gears.
  • The contact ratio is also higher.
  • The transmitted load is spread along an angled line making bending loadssmaller.
  • Tooth wear is reduced and they can transmit more power than spur gears with teeth of the same size.

SPUR GEAR HELICAL GEAR
pinion spur pinion helical
In case of spur gear, teeth are parallel to the axis of the gear. In case of helical gear, teeth are inclined with the gear axis in the form of a helix. This angle of inclination is known as helix angle (15° – 25°).
In spur gear drive, contact between teeth of two meshing gears occurs suddenly. In helical gear drive, contact between teeth of meshing gears occurs gradually.
Here the contact between two meshing teeth is always a line of same length. Here contact starts with a point, gradually becomes a line and leaves as a point.
Sudden engagement of teeth results in impact loading. So teeth are subjected to impact loading. Due to gradual teeth engagement, load on the tooth builds up gradually. So teeth are subjected to gradual loading.
Impact loading caused by sudden engagement of teeth results vibration and noise. Gradual loading provides a smooth and quite operation.
Load carrying capacity of spur gear is comparatively low. For same size and same number of teeth, load carrying capacity of helical gear is comparatively high as larger number of teeth remains in contact at any instance.
Life of the spur gears is usually shorter. Helical gears have longer life.
Two mating spur gears must have same module only. Two mating helical gears must have same module, and same but opposite hand helix angle.
Spur gears are suitable for low to moderate speed applications. Helical gears can be utilized at high speed also.
Spur gear drive produces only radial force. As the teeth are parallel to axis, the thrust force is zero. Due to presence of helix angle, helical gear drive produces radial as well as thrust force. So the bearing must be capable of sustaining such thrust force.
It is suitable for the velocity ratio of 1:1 to 1:3 It is suitable for the velocity ratio of 1:1 to 1:5
