Kawasaki KX450 Sprockets 13T & 51T, 520 Chain, Mud Notches · 模型 127263
Kawasaki KX450, 13/51 · 520 chain. Mud-race gearing: a 51T steel rear with a notch at the bottom of every tooth gap to shed packed mud, and six wide spokes, on the Japanese motocross pattern (6 × 8,5 mm on 150, 125 mm centre). Look: styled after the JT Sprockets self-cleaning steel rear (windows and mud-relief notches). Only the look is borrowed; this is a new design, not a copy of that maker's part. Parts - Front: 13T 520 countershaft sprocket, involute spline (m 1 × 20, a sample, not the bike's), nut held. - Rear: 51T 520 rear, 6 × 8,5 mm on 150 (bolt pattern approximate). Strength (an estimate) - Load: 254 N·m: the dirt bikes' load (the KX450 itself comes to about 239). - Front: 136 MPa peak · SF 3,05 in 4140 steel · rim moves 0,05 mm · 5,94 mm plate · 65 % solid. - Rear: 138 MPa peak · SF 2,25 in 1045 steel · rim moves 0,13 mm · 5,94 mm plate · 47 % solid. - Plane-stress FEM of each plate: the chain pulls on the first three engaged teeth (50/30/20 %), both directions; a rear is held at its bolts, a front at its spline. Before you make one - The front's spline (m 1 x 20 involute) is a sample, not the bike's. Change it to your countershaft's spline. - The bolt pattern and centre hole are approximate. Measure your hub or old sprocket first. - These are design samples, not tested parts. Files - STEP: kx450-13x51-drive, the drive at true size (front, rear and chain) - STEP: kx450-13x51-front and kx450-13x51-rear, each sprocket on its own - STL: kx450-13x51-front and kx450-13x51-rear, for 3D printing (with print compensation: outline slightly smaller, holes slightly larger; use the STEP for true size) Made with the CheapCADTools Sprocket Designer.
