Thus can satisfy the specific requirements of the processing. Hydraulic generators in order to meet the requirements of the large volume of usually do is larger, The weight of several tons of even a few tons. The mounting holes do not facilitate in the workshop, only at the site, So we need to design a tally with the actual situation of special drill. Our hydropower installation hole machining standby generator is always rely on imports of radial drilling machine, expensive cost is higher. Design of hydropower station in radial drill hole special generator installation is of great significance. I major in special radial drill rocker ponents research and design. According to the special requirements of the radial drilling machine design. The rocker to around the mast swing (360), Straightline movement (1000mm), Linear motor can move, After putting in place to clamp. According to the characteristics and design requirements, design below: The structure design into the rocker will bilateral type, Soon gearbox and spindle box installed in the side of the rocker respectively. The power transmission through hollow rocker to rotary parts, Finally to spindle box. The swing through radial installation guide in the post, With the guide of the ball screw ponent ball screw nut pair, Ball screw rotation, Can drive the rocker move along the pillar. Will swing to guide the block placed swing with, through the thrust bearing connection betwee
