A non-material shell finite element model is developed and applied to the example problem of a slack steel belt moving on two rotating drums. For the first time in the open literature we demonstrate an approach for predicting the time evolution of the lateral run-off velocity of the belt in response to its geometric imperfection and angular drum misalignment.

A laboratory test-rig for groundnut planter was developed for testing and calibrating the pneumatic seed metering mechanism. The experimental test rig mainly consists of main frame, seed hopper, seed metering system, power transmission system and sticky belt system. The metering unit is incorporated with a vertical seed plate held in a vacuum retaining chamber to singulate the seeds. A dial type vacuum gauge was provided in order to record the variation in suction pressure. A sticky belt was used to simulate the field surface during laboratory investigation.

A simple laboratory test-rig for maize planter was developed for testing and calibrating the electronic seed metering mechanism. The test rig consists of two frame namely main frame and the second frame. The main frame consists of variable speed drive, electric motor and grease coated belt that are fitted with necessary provisions. The second frame consists of seed hopper, seed metering unit. The metering mechanism consists of a metering roll, seed delivery box with plunger plate, proximity sensor, solenoid valve to, 12 V DC motor and the seed outlet pipe.

We have discussed earlier that the slipping of a belt or rope is a common phenomenon, in the transmission of motion or power between two shafts. The effect of slipping is to reduce the velocity ratio of the system. In precision machines, in which a definite velocity ratio is of importance (as in watch mechanism), the only positive drive is by gears or toothed wheels. A gear drive is also provided, when the distance between the driver and the follower is very small.

When compared to the constant lubrication problems associated with chain drives, or the mechanical problems and high costs associated with gear drives, belts are the most cost-effective, reliable means of power transmission. However, optimum belt drive performance requires proper maintenance. The potential for long service life is built into every Gates belt. When coupled with a regularly scheduled maintenance program, belt drives will run relatively trouble-free for a long time.

A modern motion control system typically consists of a motion controller, a motor drive or amplifier, an electric motor, and feed- back sensors. The system might also contain other components such as one or more belt-, ballscrew-, or leadscrew-driven linear guides or axis stages.
