Embodiment Construction

[0012] The specific implementation manner of the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments. Such as Figure 1 to Figure 3 As shown, a guide rail type piston rack for an electro-hydraulic switch machine includes a rack body 1, the two sides of the rack body are respectively provided with V-shaped grooves 2 along the length direction of the rack, and the rack The lower part of the body is provided with an inclined surface 3, the rack body is slidingly fitted with the inner wall 4 of the oil cylinder seat, grooves are respectively provided on the inner wall of the oil cylinder seat corresponding to the V-shaped groove and the inclined surface, and the A steel ball 5 is arranged in the groove. The V-groove is filled with grease. The guide rail type piston rack used in the oil cylinder of the present invention changes the previous sliding friction into rolling friction. The friction force is also re...

Abstract

The present invention relates to the technical field of switch machine manufacturing, in particular to a guide-rail piston rack for an electro-hydraulic switch machine, which includes a rack body. Both sides of the rack body are respectively provided with V groove, the lower part of the rack body is provided with an inclined surface, the rack body is slidingly fitted with the inner wall of the oil cylinder seat, and the inner wall of the oil cylinder seat corresponds to the V-shaped groove and the inclined surface. A groove, steel balls are arranged in the groove. The guide rail type piston rack used in the oil cylinder of the present invention changes the previous sliding friction into rolling friction. The friction force is also relatively reduced, the driving power is reduced, and the wear is reduced. The calculated maximum load capacity can reach 300 kg force, which reduces the starting pressure of the oil cylinder, improves the mechanical efficiency and ensures the service life of the oil cylinder.

Description

technical field [0001] The invention relates to the technical field of switch machine manufacturing, in particular to a guide rail type piston rack for an electro-hydraulic switch machine. Background technique [0002] The hydraulic cylinder is the energy conversion structure in the electro-hydraulic switch machine, which converts hydraulic energy into mechanical energy. The piston rack in the hydraulic cylinder transmits the force to the transmission mechanism and also meets the requirements of radial load capacity. The currently used piston rack and cylinder seat are mostly connected by sliding friction. After long-term use, the friction surface is severely worn, which affects the service life of the switch machine cylinder. Contents of the invention [0003] The object of the present invention is to overcome the disadvantages of the above-mentioned technologies, and provide a guide rail type piston rack for an electro-hydraulic switch machine, which has small friction ...
