Description

Hot Racing TRXF9312 Steel Helical Diff Ring/Pinion | ASAP Hobbies
Hot Racing TRXF9312
DESCRIPTION:
Hot Racing steel helical spiral overdrive 33T/12T gear set for 1/10 Traxxas TRX-4
Features:
Precision machined helical spiral cut gears offer inherently greater strength and smooth operation than the factory Straight cut bevel gears
High carbon steel construction
Less vibration, less noise, less wear then stock straight cut bevel gears
33T/12T provides 9% overdrive (vs stock 34T/11T) increases the wheel speed and is commonly used in the front end for digs
Works on front or rear. Use cases are typically front and rear at the same time, or front only to increase front digs
In the Package:
One (1) 33 tooth spiral cut ring gear
One (1) 12 tooth spiral cut pinion gear
Specifications:
Requirements:
Installation following kit manual
Medium threadlock (e.g. blue Loctite) if screws are threaded into metal

Straight Bevel Gear
Spiral Bevel Gear
Teeth of this type of gear are straight and are cut along the axis on a cone
Here the teeth are spiral and are cut in the form of spiral curve on the pitch cone
Two teeth of the mating gears comes in sudden contact. The contact is always a line of length equals to face width of teeth
Teeth of two mating gears gradually comes in contact. Engagement starts with a point and gradually becomes a line
Due to sudden contact, teeth are also subjected to impact or shock loading
Here teeth are subjected to gradual loading
Sudden contact also causes noise
Its operation is quite
Shock loading induces vibration and thus its operation is not smooth
Due to gradual building up of load, it produces less vibration and thus the operation is smooth
Designing and manufacturing of straight teeth bevel gear are easier and thus these are cheaper
Complicated design and manufacturing leads to higher cost for this type of gear
It exerts less thrust force on the bearings that hold the shafts
It exerts more thrust force on bearings
