Standard Stock Gears
The range of standard stock gears can be summarised as follows:

Bevel and Mitre Gears
Straight Cut Bevel and Mitre Gears manufactured to the Modul system in medium carbon steels enable simple right angle drives with reduction ratios up to 4:1. Two series of gears are offered, the first the original T.D. Cross range to imperial dimensions from 16DP to 5DP pitch, the second a much improved metric range of gears from 1 Mod. to 5 Mod. pitch. All gears can be induction or flame hardened for longer life under arduous conditions.

Spur Gears
A new range of 20° PA. spur gears all manufactured in medium carbon steel, provide selection from 1 Mod. through to 6 Mod. pitch with gears from 12 teeth to 120 teeth. Gears have face width equal to ten times Mod. number to provide sensible power transmission capability. To supplement the steel gears is a select range of cast iron wheels covering pitch range 2 Mod. to 5 Mod.with 30 to 60 tooth size.

Straight Racks
Available in standard lengths of 05, 1.0 and 2.0 metres is a range of 20° PA straight cut racks with pitch range 1 Mod. to 6 Mod. These are designed to combine with the standard spur gears to provide low cost conversion of rotary to linear motion.

Special Custom Made Gear Products
Modification of standard gears by reworking the bore and faces, and adding heat treatment often provides the most economical gear solution; but for those applications where standard gears cannot be used, special gears and racks can be manufactured within the following limits.

Mitre and Bevel Gears
Straight cut gears to the Modul System up to 250mm diameter, available in a variety of materials.

Spur Gears
In diametral or module pitch available in most sizes both 14.1/2° and 20° pressure angle up to a maximum top diameter of 56 inches in a variety of materials.

Helical Gears
With helix angles up to 45 ° maximum O/D of up to13 inches.
With helix angles up to 30 ° maximum O/D of over 13 inches to 56 inches.
Top diameter 56 inches, maximum face width 9.1/2 inches.

Straight Racks
Racks in Module or Diametral (DP) pitch can be supplied up to a maximum length of 2 metres and face width 95mm.
Maximum pitch 12 Mod, 3 D.P.
Minimum pitch 0.5 Mod, 120 D.P.

Internal Gears and Splines

Available in the range:

  • Outside diameter Max. 400mm
  • Bore diameter Max 300mm
  • Face width Max 95mm.

Splines and Serrations
Involute, flat root, or fillet root splines and serrations can be cut on machined shafts or customer blanks.
