Embodiment
, below will be to the utility model to make the purpose, technical scheme and advantage of the utility model embodiment clearer The technical scheme of embodiment is clearly and completely described.Obviously, described embodiment is that a part of the present utility model is real Apply example, rather than whole embodiments.Based on described embodiment of the present utility model, those of ordinary skill in the art are in nothing The every other embodiment obtained on the premise of creative work is needed, belongs to the scope of the utility model protection.
Unless otherwise defined, technical term or scientific terminology used herein are should be in the utility model art The ordinary meaning that personage with general technical ability is understood.Make in the utility model patent application specification and claims " first ", " second " and similar word are not offered as any order, quantity or importance, and are used only to distinguish Different parts.Equally, the similar word such as "one" or " one " does not indicate that quantity limits yet, but represents exist at least One.
The guide shoe of elevator includes the roll type guidance system using rolling friction and/or the sliding-type using sliding friction Guidance system.Roll type guidance system uses rolling friction, the advantage is that operate steadily, frictional resistance is small, operation noise it is small, Be generally used for that speed is higher and the larger elevator of load in.However, usually require to set in the guide shoe of roll type guidance system Complicated rolling member suspension, so as to need larger bulk, more part (such as multiple supporting members and rolling Part) quantity, cause it is with high costs, construction it is complicated, difficult in maintenance.Comparatively, the guide shoe of sliding-type guidance system is using cunning Dynamic friction, it is advantageous that number of parts is less, design is simple, required space is smaller thus convenient for installation and maintenance, cost is low It is honest and clean.In the prior art, more serious fretting wear would generally be occurred by sliding the surface of guide shoe, caused by friction surface compared with Big frictional force can increase elevator power consumption, and caused heat can also accelerate the damage and failure of slidingsurface in sliding friction, So as to limit use of this kind of slip guidance system in high speed, load elevators, it such as be commonly used for speed and be less than In 1.75m/s slower elevators.Accordingly, it is desired to provide improved slip guide shoe-guide rail configuration, makes to have therebetween well Friction and anti-wear performance.
The purpose of this utility model is solve above-mentioned at least one problem.More properly, it is of the present utility model Purpose is to provide a kind of sliding friction component with improved wearability and good frictional property.The utility model also aims to A kind of elevator using sliding friction component slip guide shoe component is provided.And then the utility model additionally provides one Kind includes the elevator of above-mentioned slip guide shoe component.
Coefficient of friction and wear rate are two important performance indexes that guidance system is slided in evaluation.Coefficient of friction is often referred to slide The frictional force and the ratio of normal pressure born on dynamic surface.Wear rate is often referred to the unit under the normal force effect of unit-sized Wear volume amount caused by the sliding distance of length.As an example, in conventional elevator system, if elevator is between floors The vertical stroke of maximum be 50m, annual to be more than startup 100000 times, then total sliding distance of elevator is about annual 2500km. In practice, year total sliding distance of elevator can also be up to annual 6000km.In addition, if allowing lift car and with focusing on cunning Annual 0.2mm wear extent is produced on dynamic guide shoe surface under per unit size (1N) normal pressure, with sliding contact table Face area is 1000mm2Exemplified by, then the Volume erosion rate for the maximum unit road length that guide rails are allowed be less than 8 × 10-5mm3/Nm。
