Description

Technical Field

[0001] The utility model relates to the technical field of reducers, in particular to a precision planetary reducer which is easy to install and disassemble. Background Art

[0002] Precision planetary reducers are another name for planetary speed reducers in the industry. Their primary transmission structure consists of planetary gears, a sun gear, and an internal ring gear. Compared to other speed reducers, precision planetary reducers offer high rigidity, high precision (single-stage accuracy can be within 1 minute), high transmission efficiency (97%-98% per stage), a high torque-to-volume ratio, and lifetime maintenance-free operation. They are often installed on stepper and servo motors to reduce speed, increase torque, and match inertia. However, reducers are typically mounted inside a base or protective housing to enhance stability and mitigate safety risks. However, these reducers require connection to the motor's output shaft. Existing connections often require numerous bolts or the removal of flanges, significantly increasing the complexity and difficulty of operation and reducing the efficiency of speed reducer installation and maintenance.
