~ Service life increased to more than 2 times ~
Recently, JTK Group announced that it has successfully developed a new long-life riveted shaft for planetary gears, which is used in planetary gear units of automatic transmissions (stepper AT, CVT, HV).
The newly developed planetary gear shaft with a special heat treatment technology, its ends by riveting fixed to the planet carrier, improved overall durability, life expectancy has reached more than 2 times.Thus, the entire planetary gear The miniaturization of the unit and the reduction of the weight and efficiency of the transmission assembly are all expected to be improved.

1. Features
(1) using riveting fixed way
(2) improve the service life of the shaft
The newly developed planetary gear shaft with a special heat treatment technology to improve the roller rolling surface hardness, while maintaining a fixed part of the low hardness (see below) .Thus, by 'riveting' fixed Way to make the whole planetary gear miniaturization, roller rolling surface durability, successfully reduced the shaft deformation, the shaft life can be increased to more than 2 times.
