Description
Technical field
This utility model relates to a kind of swelling shaft, more specifically, it relates to a kind of swelling shaft processing flexbile gear.
Background technology
Harmonic wave drive speed reducer is dependent on flexible part and produces elastic mechanical ripple to transmit a kind of mechanical driver of power and motion. Harmonic drive includes three basic building blocks: wave producer, flexbile gear and just taken turns. Three components arbitrarily fix one, and in other two is that actively another is driven, it may be achieved slow down or speedup (fixed drive ratio), it is possible to be transformed into two inputs, and an output forms differential gearing. Maintain static as just taken turns, with wave producer for driving link, flexbile gear is driven member, oval cam in wave producer rotates in flexbile gear and just makes flexbile gear be deformed, the flexbile gear gear teeth at the oval cam major axis two ends place of wave producer and just the wheel gear teeth enter when engaging, and the flexbile gear gear teeth at short axle two ends place disengage with the just wheel gear teeth. For the gear teeth between major axis of wave generator and short axle, it is in, along flexbile gear and the firm different sections taking turns girth, the semi-engagement state progressing into engagement, is called engaging-in; It is in the semi-engagement state being gradually backed out engagement, is called and nibbles out. The continuous rotation of wave producer, make engaging-in, engage, nibble out and disengage four kinds of motions and constantly change each original duties, this motion is called that side set move, and side set motion makes input rotate to become exporting and move.
Harmonic drive has that gear ratio is big and scope is wide, precision is high, backlash is little, bearing capacity is big, volume is little, lightweight, transmission efficiency is high, stable drive, noise are little, can, to advantages such as confined space transmitting movements, apply more and more extensive in recent years.
