Product Overview
The LGH75 Series planetary gearbox by Matex Japan is designed for high-performance applications, offering a gearhead type with an outer diameter of 90 mm and a torque range of 22.6 to 34 Nm. The product is part of the 'We Discover Tomorrow' initiative, emphasizing innovation and reliability.

Model Naming Rule
The model naming convention includes the gearhead type, outer diameter, nominal speed ratio, material and width of the gear, input shape, and diameter of the output shaft. This systematic approach aids in identifying the specific configuration and capabilities of each gearbox model.

Structure of Gearhead
The gearhead comprises several key components: the gear case, planetary gear unit, ball bearing, oil sealing, output shaft, and fixing screw. Grease is pre-injected during manufacturing to ensure smooth operation.

Installation Requirements
Users must prepare a flange and coupling to connect the gearbox to a motor. It is crucial to verify the life expectancy of the output shaft bearing, especially when radial loads are applied. The calculation involves factors such as equivalent dynamic load, radial load position, output revolution, drive coefficient, and impact coefficient.

Life of Output Shaft Bearing
The life expectancy of the output shaft bearing is influenced by the drive and impact coefficients. The drive coefficient varies based on the connection type (chain, gear, belt), while the impact coefficient depends on the level of impact (almost zero, slight, or hard impact).

Dimensions and Output Torque
The LGH75 Series offers various models with different speed ratios and output torque capabilities. The output torque curve illustrates the relationship between output torque and revolution speed, providing insights into performance under different operational conditions.
