Description
Technical Field
The utility model belongs to the technical field of bearing design and manufacturing, concretely relates to bearing and use plunger hydro-cylinder of this bearing.
Background
In the mechanical industry, a bearing is an important part for transmitting power, the plunger oil cylinder needs to have enough guide due to large lateral stress, and a self-lubricating bearing needs to be selected as the guide due to the fact that a common guide ring is limited by space and the guide length is not enough.
The self-lubricating bearing is divided into a composite material self-lubricating bearing, a solid embedded self-lubricating bearing, a bimetallic material self-lubricating bearing and a special material self-lubricating bearing, and different self-lubricating bearings are selected according to different purposes and working conditions. One of the major solid inlaid self-lubricating bearings (JDB for short) is a novel lubricating bearing with both the characteristics of metal bearing and oil-free lubricating bearing, and the load is borne by the metal matrix, and the solid lubricating material with special formula has the lubricating effect. The oil film has the characteristics of high bearing capacity, impact resistance, high temperature resistance, strong self-lubricating capacity and the like, is particularly suitable for occasions which are difficult to lubricate and form oil films, such as heavy load, low speed, reciprocation or swing and the like, and is not easy to be affected by water flushing and erosion and flushing of other acid liquid. But common solid is inlayed from lubricating bearing only opens there is the through-hole on the bearing body, inlays solid lubricating material in the through-hole, and this kind only relies on lubricated bearing lubricating property of solid lubricating material relatively poor, causes the wearing and tearing of bearing and axle easily, and the life of bearing and axle is short, needs to improve the lubricated reliability of bearing urgently.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the defect and not enough that exist among the prior art, provide a simple structure, reliable and stable, the direction is effectual, the plunger cylinder of bearing and use this bearing that lubricating property is high.
In order to achieve the above object, the utility model adopts the following technical scheme: the utility model provides a bearing, includes bearing body and bearing frame, bearing body includes back of the body and suit in the back of the body, and with the inside lining of the coaxial setting of back of the body, the inside open slot that is equipped with of bearing frame, the back of the body sets up in open slot, the inside lining is close to back of the body one side and is equipped with the elastic layer, the inside lining is kept away from back of the body one side and is equipped with the lubricating layer.
Preferably, the lining is provided with a lubricating groove communicated with the oil guide groove on the backing.
Preferably, the lining is provided with a plurality of mounting holes, and the lubricating layer is fixed in the mounting holes.
