Description
Technical field
This utility model relates to a kind of excavator oil cylinder, is specifically related to a kind of excavator oil cylinder with cushioning effect.
Background technology
Excavator closely becomes one of topmost engineering machinery type in engineering construction. Known excavator power at work is mainly derived from hydraulic jack, when the piston rod in hydraulic jack is elongated to the longest end, very big impulsive force can be produced, can be that scraper bowl is impaired when running into hard object, in-oil cylinder part can be influenced by damaging, particularly cylinder body and piston rod; When piston rod bounces back to most short end, also producing very big impulsive force, cause that car body shakes, virtually shorten the service life of oil cylinder, structure is complicated, and processing difficulties, buffering and damping effect is undesirable, and the global reliability of oil cylinder is poor.
Utility model content
For problem above, this utility model provides a kind of excavator oil cylinder with cushioning effect, this utility model extends the service life of oil cylinder, reasonable in design, simple in construction, both can guarantee that the reliability of hydraulic jack complete machine still, and the global reliability adding again oil cylinder is poor, structural strength is high, have and well seal and cushioning effect, the impulsive force of generation during flexible work can be completed by buffering hydraulic oil cylinder to a certain extent, it is possible to effectively solve the problem in technical background.
To achieve these goals, the technical solution adopted in the utility model is as follows: a kind of excavator oil cylinder with cushioning effect, including cylinder barrel, described cylinder barrel includes cylinder tail, cylinder cap and head, described cylinder tail is provided with little steel bushing, described little steel bushing is provided with grease nipple, described cylinder barrel is provided with piston rod and piston, described piston rod is vertical with cylinder barrel, described piston is connected with piston rod, described piston is provided with steel ball, described piston is fixing on the piston rod by lock-screw and nut, described cylinder cap is fixed on cylinder barrel by hexagon socket head cap screw, described cylinder cap is provided with steel wire clamping ring, it is connected to oiliness bearing between described cylinder cap and cylinder barrel, buffering ring, main oil sealing and dust ring, described head is provided with big steel bushing.
Further, it is provided with wear ring between described piston and cylinder barrel.
Further, it is provided with Glais ring between described piston and cylinder barrel.
Further, scrubbing ring it is provided with between described piston and cylinder barrel.
Further, described cylinder cap is provided with O.
The beneficial effects of the utility model:
This utility model extends the service life of oil cylinder, reasonable in design, simple in construction, both can guarantee that the reliability of hydraulic jack complete machine still, the global reliability adding again oil cylinder is poor, structural strength is high, have and well seal and cushioning effect, the impulsive force of generation during flexible work can be completed by buffering hydraulic oil cylinder to a certain extent.
Accompanying drawing explanation
