Design of a Planetary Reduction Gearbox for a Hydraulic Roller Press of the Cement Industry

Gearbox has been standardised by well-developed and established Standards like AGMA and DIN. A detailed guidelines and recommendations are available for varieties of application for design as well as manufacturing and quality. But, design of gearbox for a new application is always a challenging task. Understanding of application loading condition is needed in designing of accurate, economical and reliable gearbox. In addition, load is fluctuating with time. Such application requires fatigue conditions to take into consideration. Studies are required to estimate loading conditions. Such studies will help in designing application specific conditions, and may lead to better performance, less cost and compact design. Design of gearbox by taking into consideration of equivalent torque found from the fatigue loading of the Hydraulic Roller Press is presented in this Paper. To develop loading characteristics of an application, detailed study of application function is required. This application study of present application of hydraulic roller press is carried in this Paper. Loading pattern for particular application is developed by observation of power v/s time curve. DIN 3990 Standard is used to make the design more accurate and standardized.
