Bevel and Mitre Gears

Two series of gears are offered:

– The original T.D. Cross range to imperial dimensions from 16DP to 5DP pitch of standard Mitre and Bevel gears, stocked in pilot bore form with reboring, keywaying and induction hardening available. When correctly aligned, a bevel gearset with oil lubrication can operate with transmission efficiency up to 98 percent.

– The much improved metric range of gears from 1 Mod. to 5 Mod. pitch to provide the designer with a wider range of selection. All gears manufactured in medium carbon steels for high strength and durability and can be rebored, keywayed and induction/flame hardened for more arduous applications.

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 to your specifications. View Special Custom Made Gears

Spur Gears

A 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, with or without a hub. Gears have face width equal to ten times Mod. number to provide sensible power transmission capability.

Straight Racks

These provide the ideal method to convert rotary into linear motion for table drives etc. or linear to rotary motion as in feeds. In addition to the standard range of racks special constructions can be provided with pitch size up to 16 mod.

Available in standard lengths of 0.5, 1, 2 and 3 metres is a range of 20° PA straight cut racks with pitch range 1 Mod. to 8 Mod. These are designed to combine with the standard spur gears to provide low cost conversion of rotary to linear motion.

Racks can be supplied modified to enable easy mounting by addition of plain or tapped holes.
