with blind angle can be made, which can eliminate undercutting and retracting grooves when cutting gears. When making this kind of gear by powder metallurgy, special support is needed at the blind end.
(4) Gear can be combined with other shape parts, such as cam, ratchet, other gears, etc., and integrated production can be realized by powder metallurgy process.
(5) Bevel gears, bevel gears with equal diameter, helical gears and other https://nobuyuki-shirai.com special tooth-shaped gears can be made.
(6) Standard involute gears can be made, which is simpler and cheaper than other methods.
(7) The ratchet wheel, like the gear, is easily manufactured by powder metallurgy and MIM. Root cutting should be avoided, and large radius should be allowed at the top and root of teeth.
Powder metallurgy and metal injection molding have the characteristics of excellent surface roughness, uniform performance among parts and self-lubrication, which is especially advantageous for making gears and cams. Sintered cams with self-lubricating properties often have more durable surfaces than grinders. Powder metallurgy gears can be formed at one time, which not only saves cost, but also improves productivity.
