Abstract
The utility model relates to a wet-type friction plate which is a friction plate working by immersed in oil and specially suitable to be used in a break or a stop device of an elevator or a hoist for controlling the drop of a load. The friction plate is composed of two paper made friction plate bodies (1) and a metal chip (2) clamped between the two paper made friction plate bodies (1). When the utility model is used, the metal chip (2) between the two paper made friction plate bodies (1) plays the action of support so as to enhance the resistance and the impact resistance of the friction plate; the utility model can bear large brake pressure and normally work for a long time under the condition of frequent starting and braking impact; service life is prolonged.
Description
The utility model relates to a kind of wet friction sheet, is a kind of friction plate of working in the oil that is dipped in, and is particularly suitable for using at the braking or the arresting stop that are used for control load decline of lift or winch.
In the prior art, the wet friction sheet generally is the annular graphite lamellar body that adopts the asbestos resin material ring slice that grinding forms after the high pressure-temperature compacting or adopt metallurgical powder technology to make.Wearability is stronger, but lower because of its intensity, impact resistance is poor, is easy to fragmentation.The goliath of smelter particularly, as be used for State of Blast Furnace front boom pneumatic hoist in the maintenance of taphole place frequent handling molten iron operculum colpi, clay gun and other operation, friction plate in its break will frequently bear the braking impact force, and it is under higher retardation pressure, work for a long time, thereby broken easily.In case friction plate fragmentation, pneumatic hoist be with regard to cisco unity malfunction, and directly influence the blast furnace casting process.In addition,, consume lot of manpower and material resources, increased cost of production because of need often keep in repair.
The purpose of this utility model provides the good wet friction sheet of a kind of wearability, intensity and impact resistance tool, to improve its working life, guarantees normally carrying out of production, reduces production costs.
The purpose of this utility model is achieved through the following technical measures.
A kind of wet friction sheet is ring slice.This friction plate is made up of the two layers of paper preparation of friction wafer body metal chip middle with being sandwiched in this two layers of paper preparation of friction wafer body.
Metal chip is a spring steel plate, utilizes the elasticity of spring steel itself, makes friction plate be easy to recover its original shape after external force is cancelled, and keeps its good braking effect.
Introduce embodiment of the present utility model below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of the utility model wet friction sheet.
Fig. 2 is the side direction view of Fig. 1.
The utility model wet friction sheet, as shown in Figure 1 and Figure 2, coating adhesive between two layers of paper preparation of friction wafer body 1 and spring steel plate 2, after high pressure-temperature compacting and grinding, promptly constitute the wet friction sheet that the utility model is made up of two layers of paper preparation of friction wafer body 1 and the spring steel plate 2 in the middle of being sandwiched in again.
During work, the spring steel plate 2 in the two layers of paper preparation of friction wafer body 1 plays a supportive role, and has increased the intensity and the impact resistance of friction plate, can bear bigger retardation pressure under the condition that frequently opens the braking impact, and long-time proper functioning.Show that through on-the-spot the trying out of State of Blast Furnace front boom pneumatic hoist can reach more than 5 years the working life of the utility model wet friction sheet.
Compared with prior art, the utility model Wet-type friction slice rationally utilizes mar proof and the metal of paper High strength and resistance to impact, greatly improve service life, reduced the maintenance of equipment amount, prolonged equipment Work online the time, what guaranteed to produce normally carries out. Simultaneously, saved the maintenance of equipment expense, fallen Low production cost.
