Abstract

The invention belongs to the field of mechanical manufacturing, and particularly relates to an end cover of the servo oscillating type hydraulic cylinder. The end cover comprises a cover body and an axial hole formed in the middle of the cover body. According to the end cover of the servo oscillating type hydraulic cylinder, oil ways are reasonably arranged in the end cover and communicate with oil holes formed in the end cover, and therefore radial bearings and axial thrust bearings can be simultaneously arranged on the end cover. In this way, the limitation that the end cover only achieves the fixing and sealing effects in the past is broken through, creative breakthrough is achieved, and the obvious significance on improvement of the overall functions of the hydraulic cylinder is achieved.

Description

technical field [0001] The invention belongs to the field of mechanical manufacturing, in particular to an end cover of a servo swing hydraulic cylinder. Background technique [0002] Swing servo hydraulic cylinders generally include end caps, stators and rotors, among which the end caps mainly play the role of sealing, fixing the stator and rotor, and external assembly. The design and production of the existing products are also concentrated here. Several aspects. At present, there is no document recording the functional creative design of the end cover to endow the end cover with new functions and improve the overall performance of the hydraulic cylinder. Contents of the invention [0003] The invention discloses a static pressure support type hydraulic cylinder end cover. By arranging oil passages in the end cover, the limit of the end cover only serving as fixing and sealing is broken, and the end cover is endowed with a new function as a static pressure bearing. The...
