Abstract
The utility model discloses a lifting oil cylinder, and relates to a one-way motion executing machine in a hydraulic system, in particular to a structure of an oil cylinder. The lifting oil cylinder comprises a fixing base plate, a cylinder body is arranged above the fixing base plate, a piston rod is arranged in the cylinder body in a penetrating mode, one end, located outside the cylinder body, of the piston rod is connected with a lug ring, the lug ring is provided with a lug hole, a self-lubricating thrusting knuckle bearing is arranged between the fixing base plate and the cylinder body, and a self-lubricating radial knuckle bearing is arranged in the lug hole. According to the lifting oil cylinder, the self-lubricating thrusting knuckle bearing is additionally arranged on the basis of an original fixing base plate and an original cylinder body of the lifting cylinder, meanwhile, the self-lubricating radial knuckle bearing is adopted for the connecting position of the lug ring, under the one-way load bearing condition, space adjustment motion can be carried out on a spherical surface sliding bearing, and the bearings can bear radial loads, axial loads and mixed loads, and the motion service life is long.
Description
Technical field
The utility model relates to the execution machinery of doing unidirectional movement in hydraulic system, relates in particular to the structure of oil cylinder.
Background technique
In hydraulic system, make the execution machinery of unidirectional movement, retracting is mainly to carry out by deadweight or other actuator.Be applicable to the occasions such as metallurgy (continuous casting, tandem rolling), iron and steel processing.The earrings joint of existing hoist cylinder adopts common joint shaft bearing, easy to wear, and cylinder body adopts fixing bottom-plate to connect, and is subject to the impact of mixed load, and working life is not long.Replacement cost is high, not easy care.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, and long hoist cylinder of a kind of not easy to wear, life-span is provided.
The purpose of this utility model is achieved in that hoist cylinder, comprise fixing bottom-plate, the top of fixing bottom-plate arranges cylinder body, in cylinder body, place piston rod, one end connecting lug of the piston rod outside cylinder body, earrings arranges earhole, and selflubricating thrust articulated bearing is set between described fixing bottom-plate and cylinder body; In described earhole, self-lubricating plain radial bearing is set.
The utility model increases selflubricating thrust articulated bearing to the original fixing bottom-plate of product and cylinder body; Earrings joint adopts self-lubricating plain radial bearing simultaneously.Be subject under unidirectional load condition, spherical bearing allows space allocation motion, and according to bearing can support radially, axially, the load that mixes.Sport life span is more permanent.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is the side view of Fig. 1.
Embodiment
As shown in Figure 1, 2, be hoist cylinder, comprise fixing bottom-plate 1, the top of fixing bottom-plate 1 arranges cylinder body 2, between fixing bottom-plate 1 and cylinder body 2, selflubricating thrust articulated bearing 7 is set.In cylinder body 2, place piston rod 3, one end connecting lug 4 of the piston rod 3 outside cylinder body 2, earrings 4 arranges earhole 6, the interior self-lubricating plain radial bearing 5 that arranges of earhole 6.
Claims (1)
1. hoist cylinder, comprises fixing bottom-plate, and the top of fixing bottom-plate arranges cylinder body, in cylinder body, place piston rod, one end connecting lug of the piston rod outside cylinder body, earrings arranges earhole, it is characterized in that: selflubricating thrust articulated bearing is set between described fixing bottom-plate and cylinder body; In described earhole, self-lubricating plain radial bearing is set.
