The EP-BADR series high-precision planetary gearbox<\/strong> combines three capabilities in a single unit: a 90\u00b0 right-angle output<\/strong> via a precision bevel input stage, a round circular-flange output<\/strong> for cylindrical bore mounting, and the widest gear ratio range<\/strong> in the Korea Ever-Power right-angle product family \u2014 single-stage to 20:1 and two-stage to 200:1. It is the natural choice when a machine design requires all three of these properties simultaneously: right-angle torque redirection, circular bolt-circle mounting, and high reduction ratio.<\/p>\n

Across all seven frame sizes from EP-BADR047 through EP-BADR255, the full P1 backlash specification of \u22643 arcmin single-stage and \u22645 arcmin two-stage<\/strong> is maintained at the output shaft \u2014 including the bevel stage contribution. Combined unit efficiency reaches \u226593% single-stage and \u226590% two-stage<\/strong>, far exceeding worm gear alternatives at equivalent ratios. Full-body hardened alloy steel gears, ANSYS-validated tooth corrections, and an integrated one-piece planet carrier and output shaft deliver the long-term backlash stability that Korean AGV, cobot, and automation equipment manufacturers demand.<\/p>\n

Where EP-BADR Fits \u2014 The Right-Angle Round-Flange Matrix<\/h2>\n

Korea Ever-Power’s right-angle planetary gearbox and round-flange variants form a 2\u00d72 selection matrix. EP-BADR occupies the cell requiring both<\/em> right-angle output and round circular-flange mounting \u2014 the most specialised configuration, and the one with the widest available ratio range.<\/p>\n

Applications \u2014 Where Right-Angle Output Meets Round-Flange Mounting<\/h2>\n

Cylindrical-Housing AGV Steering with High Reduction<\/h3>\n

AGV omni-directional drive modules package the steering actuator inside a cylindrical pivot housing that rotates above the drive wheel. A round-flange right-angle gear reducer fits directly into this housing with its circular bolt-circle clamping against the bore shoulder \u2014 while the 90\u00b0 bevel stage keeps the servo motor horizontal, parallel to the floor, rather than protruding vertically above the module height limit. Where very slow steering sweep rates require high reduction ratios, BADR’s 200:1 two-stage eliminates the additional worm stage that otherwise adds 60\u201380 mm to the module height. Pairs with CV drive shafts<\/a> for differential-drive AGV wheel offset configurations.<\/p>\n

Cobot Joints with Cross-Axis Cable Pass-Through<\/h3>\n

Some cobot joint configurations route power and signal cables through the joint axis \u2014 perpendicular to the link direction \u2014 requiring a hollow-shaft right-angle drive. EP-BADR’s round flange mounts into a hollow-bore circular housing where cables pass through the bolt-circle centre while the bevel stage redirects motor torque 90\u00b0 to the hollow output shaft. The i=14 and i=20 single-stage options provide the compact axial length critical for cobot wrist joints where every millimetre of length affects end-effector reach within the robot’s rated payload envelope.<\/p>\n<\/div>\n

\n

Solar Tracker Column Drives (Round Pillar Mounting)<\/h3>\n

Single-axis solar trackers built on round steel pipe columns mount the tilt actuator inside the column bore. EP-BADR’s round flange bolts directly to the column bore flange without a transition bracket, while the 90\u00b0 output drives the tracker torque tube horizontally from a vertically-mounted motor. At 50:1\u2013100:1, EP-BADR provides the required tilt torque across Korea’s utility-scale solar installation wind load ratings, with the sealed-lube unit requiring zero field maintenance over the tracker’s 25-year design life. Secondary power split through bevel stages<\/a> enables one drive unit to actuate both tracker array halves.<\/p>\n<\/div>\n<\/div>\n
