COMPONENT REQUIREMENTS

Worm wheel blank

Define the geometry, material, delivery condition and acceptance criteria for the selected application. Manufacturing scope requires review of the approved drawing and operating requirements.

COMPONENT GUIDE

Worm wheel blank

Roll-gap adjustment or other drawing-specified bronze worm drive.

Provides the blank for a specified auxiliary transmission wheel.

Manufacturing & delivery form
Cast solid or ring blank with agreed premachining; tooth cutting specified separately.

Confirm blank, pre-machined or finished-wheel delivery. Tooth cutting, gear accuracy and final inspection require explicit agreement.

Material candidates

UNS C90700 Tin bronze

Candidate for gear and worm-wheel blanks.

Confirm the mating gear, lubrication and machining scope. An alloy designation does not establish finished gear accuracy.

UNS C90500 Tin bronze

Candidate for drawing-defined gear blanks and selected lubricated components.

Confirm the governing standard, casting form and duty. C90500 and C90700 are distinct grades.

Confirm the drawing, actual duty, material standard and manufacturing condition. Material substitutions require customer approval, and supply scope is agreed after component review.

Component RFQ requirements

Blank structure: Hub/rim arrangement, bore, outside diameter and web.
Machining allowance: Datums, turning allowance and downstream tooth-machining scope.
Mating drive: Worm definition, connection geometry and counterface material.
Operating conditions: Load, speed, lubricant and required hardness condition.
Material & acceptance: Specified alloy and standard, supply condition, drawing revision, quantity, inspection criteria and required records.
Supply form: Cast solid or ring blank with agreed premachining; tooth cutting specified separately.

Start with your drawing, specified alloy and quantity. Include the required delivery condition and acceptance records so the manufacturing and inspection scope can be reviewed.
