Harmonic reducer—HRV160E reducer application case in turntable

Generally speaking, instruments or equipment with turntables can be referred to as "turntables", such as servo turntables, rate turntables, and other specialized instruments used for gyroscope testing.
However, the commonly referred to "turntable" does not refer to these specialized instruments, but to the widely used and versatile rotary worktable, which is not only an important indexing accessory in machine tool processing, but also an important tool.
During processing, the turntable can be used in conjunction with ordinary drills, milling machines, precision milling machines, boring machines, grinding machines, coordinate boring machines, etc., to detect drilling dies, indexing plates, gears, cams, templates, polyhedra, end gear discs, as well as parts with precision angles such as aviation engine casings, turbine discs, composite drilling dies, etc.
At present, the common rotating shaft dragging schemes for turntables are direct drive motors and worm reducers.
The advantages of a direct drive motor are: simple structure, high transmission rate, high accuracy, and good dynamic response; The disadvantages are: high cost, poor rigidity, inability to withstand instantaneous impacts, and large volume. The advantages of a worm gear reducer are: high output torque, impact resistance, good rigidity, and the ability to lock in reverse; The disadvantages are: large volume, low accuracy, high vibration, and poor wear resistance.
The harmonic reducer, HRV160E reducer, has high accuracy, small volume, and large load-bearing capacity, making it particularly suitable for application on rotating shafts in small machining centers. This article introduces a scheme of integrating a harmonic reducer with a driving motor and applying it to the rotating shaft of a turntable.
