TECHNICAL SPECIFICATION FOR HYDRAULIC DRIVE & CONTROL CIRCUIT OF GIMBLE ASSEMBLY
1) Introduction:
A hydraulic drive system along with its control is as per shown fig 1&2.
Two linear actuators drive along with chain & sprocket arrangement rotates a shaft with given torque requirement in both the direction. This whole arrangement is to be supported on support structure. This load is to be transfer on structure & is to be hinged & supported on ground. To give an angular movement to whole support structure another two linear actuator is to be provided, this is to be hinged at centre & give angular movement 25° up & 25° down. The Linear actuators with chain & sprocket arrangement rotate shaft180 ° max in ten hours. For achieving this slow rotational speed of 180 °/ 10 hours or approximate 18 °/hr. hydraulic linear actuator have been selected. Other two actuators set will hold up the whole load of structure as well it rotate 25° up & down in complete year.
