An electric cylinder with a buffer

Abstract

An electric cylinder with a buffer, which consists of a screw rod integrated with the motor rotor, angular contact ball bearings, annular thrust pads 1, 2, long bolts, upper cylinder of the electric cylinder, motor stator, splines, and an encoder , end cover, threaded ball, nut barrel, retaining ring, electric cylinder block, piston ring, buffer inner cylinder, buffer outer cylinder, sealing gasket, retaining ring, ring spacer, rigid spring and bracket, motor rotor It is an integrated structure with the lead screw. As the stator end of the motor, the lead screw is supported in the upper cylinder of the electric cylinder through angular contact ball bearings, and extends into the upper cylinder of the electric cylinder to cooperate with the motor stator to form a motor. The two ends of the motor stator are equipped with annular thrust pads 1 , 2; The threaded end of the lead screw is composed of a threaded roller and a nut barrel to form an electric cylinder transmission device, which is contained in the nut barrel and the electric cylinder body. The instantaneous impact load of the electric cylinder during start-up and impact is reduced, and its service life is effectively improved.

Description

Technical field: [0001] The invention relates to an electric cylinder with a buffer, which can be applied to occasions such as linear transmission, heavy load, and high-frequency impact.
