Embodiment Construction

[0010] Such as figure 1 As shown, the present invention is provided with a piston rod 2 inside the cylinder 1, a piston 4 is locked at one end of the piston rod 2 through a lock nut 3, and the piston rod 2 is sleeved in the cylinder through a guide sleeve 5, and the guide A dust-proof ring 6, a step seal 7, a first support ring 8, a piston rod sealing ring 9, an O-ring 10, and a retaining ring 11 are installed in the outer diameter and inner diameter groove of the sleeve 5, and a grid is installed on the piston 4. Lai ring 12, the second support ring 13. Through the above settings, when the piston rod 2 is extended and retracted in the present invention, the gray ring 12 on the piston 4 acts as a main seal, and the second support ring 13 provides lateral support; the dust-proof ring 6 on the guide sleeve 5 scrapes In addition to external impurities to prevent damage to the seal from entering the oil cylinder, the piston rod sealing ring 9 compresses the piston rod 2 and the g...

Abstract

The invention discloses a steering oil cylinder of a loader, and is characterized in that a piston rod is arranged in a cylinder barrel, one end of the piston rod is locked with a piston through a lock nut, the piston rod is sleeved in the cylinder barrel through a guide sleeve, a dustproof ring, a step seal, a first support ring, a piston rod sealing ring,, an O-shaped ring and a retainer ring are arranged in grooves at the outer diameter and the inner diameter of the guide sleeve, and the piston is provided with a glyd ring and a second support ring. Through the setting, the steering oil cylinder has the advantages of good sealing property, simple and compact structure and difficulty in looseness of the piston, and conforms to special working requirements of the steering oil cylinder.

Description

technical field [0001] The invention relates to a loader oil cylinder, in particular to a steering oil cylinder of a loader. Background technique [0002] At present, the loader has long working hours, high working frequency and poor working environment. The steering cylinder must have good sealing performance, long working life and compact structure in the whole machine. Contents of the invention [0003] The present invention designs and develops an oil cylinder with good sealing performance and simple and compact structure aiming at the current actual working conditions of the steering oil cylinder of the loader. [0004] The present invention is achieved through the following technical solutions: [0005] There is a piston rod inside the cylinder, and a piston is locked at one end of the piston rod through a lock nut. The piston rod is fitted in the cylinder through a guide sleeve, and a dust-proof Ring, Step seal, the first support ring, piston rod sealing ring, O-r...
