Psylogic has been contributing to the annual production of more than 300,000 EA and defect detection by applying the transmission error measurement system to the gear mass production lines of Hyundai Motors, Neo oto, and DIC since 2012.
supporting the detection of defective teeth, gear nick and scales through the initial tryout, and educate/cooperate in managing various codes.

There are few devices around the world that measure the transmission error for planetary gears. Also, it is difficult to configure the load tester. Therefore, in most automatic transmission production lines, after assembling the transmission, a load test is performed, and if the planetary gear is noisy, it is disassembled and repaired. When using the planetary gear carrier pack transmission error tester developed by Psylogic, it is possible to evaluate the transmission error for individual planetary gears and to detect defects such as (1) noise defects and (2) parts binding in advance.

MDPS (Motor Drive Power Steering) is a device that assists steering force using a motor. It has a worm & wheel structure to obtain a high gear ratio. The worm gear connected to the motor rotates the wheel to obtain high torque. However, it is very difficult to measure the degree of meshing between the Worm & Worm Wheel gears.
 The MDPS transmission error tester developed by Psylogic can evaluate the steering performance and processing errors of gears by measuring the transmission error between the worm and the wheel.

The gearbox of the steering system is a device that converts the rotational motion of the pinion into the linear motion of the rack. In Psylogic, a rotary encoder was installed on the pinion and a linear encoder was installed on the rack to obtain the transmission error between the rack and the pinion. This will be an important factor in identifying and diagnosing the cause of noise in the steering gearbox.
