Screwdown Gearbox parts diagram: 1 helical gear pair, 2 gearbox housing, 3 ball bearing, 4 oil seal, 5 servo motor. 35 parts in 5 assemblies. — Screwdown Gearbox parts diagram. Numbers match the table below; each box is one top-level part or assembly with what it contains.

#	Part	Qty	What it does
1	Helical Gear Pair	2×	Two meshing helical gears forming one reduction stage that steps torque up and speed down between parallel shafts with quiet, continuous tooth contact.
2	Gearbox Housing	1×	Rigid cast housing that holds the gears and bearings in alignment, contains the lubricant, and mounts the gearbox to the machine.
3	Ball Bearing	6×	Deep-groove radial ball bearing.
4	Oil Seal	2×	Spring-loaded rotary lip seal that keeps lubricant inside a housing and dirt out where a shaft passes through, sized to DIN 3760.
5	Servo Motor 4 parts	1×	Brushless motor with an integrated encoder or resolver, driven in closed loop to hold commanded position, speed, or torque precisely.
