Description
Technical field
The utility model belongs to the spring coiling machine technical field, relates generally to a kind of Digital Control Plane Roll-up Spring machine feed mechanism AC servo motor damping device.
Background technology
The feed mechanism of Digital Control Plane Roll-up Spring machine reduces part and is complementary in the hope of the inertia that satisfies transmission mechanism and the inertia of AC servo motor in order to shorten driving-chain as far as possible, generally all motor directly is connected with gear shaft by shaft coupling, but what this structure adopted is rigid coupling, the inertia of feed mechanism will cause the motor vibrations when the moment of electric motor starting, the number of starts of the feed mechanism of Digital Control Plane Roll-up Spring machine is 50-200 time/minute (its highest number of starts difference of different type of machines), and AC servo motor will cause the damage (using 2-6 month motor promptly can not run well) of encoder as the SCM-580CNC Digital Control Plane Roll-up Spring machine that certain factory produces through long vibrations
Summary of the invention
The purpose of this utility model is to propose a kind of Digital Control Plane Roll-up Spring machine feed mechanism AC servo motor damping device, frequently cause motor encoder to damage problem in order to solve Digital Control Plane Roll-up Spring machine feed mechanism AC servo motor because of starting, improve the service life of feed mechanism AC servo motor.
The utility model is finished the technical scheme that its invention task taked:
A kind of Digital Control Plane Roll-up Spring machine feed mechanism AC servo motor damping device, primary structure is a star yielding coupling, the output shaft that is arranged on the AC servo motor on the lathe casing is connected with gear shaft by the star yielding coupling, described star yielding coupling has left semi-convex shape rest shoe, right semi-convex shape rest shoe, and the semi-convex shape rest shoe in a described left side, right semi-convex shape rest shoe are connected with output shaft, the gear shaft of AC servo motor by flat key respectively; The semi-convex shape rest shoe in the described right side is provided with groove, is provided with the star elastomer in the groove.
The utility model proposes a kind of Digital Control Plane Roll-up Spring machine feed mechanism AC servo motor damping device, the star elastomer of the star yielding coupling of this device can absorb the vibrations that transmission mechanism produces effectively, thereby the encoder of AC servo motor can not damaged because of the vibrations that the AC servo motor Fraquent start produces, improved the service life of feed mechanism AC servo motor.
