Abstract

A composite guide shoe bush comprises a damping substrate and a working face. Wherein the damping substrate with a working face stuck in the damping substrate is embedded in the guide shoe, a binding material is provided between the damping substrate and the working face, the damping substrate is made of rubber in particular to an oil resistant rubber and the working face is made of modified polytetrafluoroethylene. The utility model not only satisfies the need of damping, but suits the requirement of working atmosphere of the guide shoe. As using the modified polytetrafluoroethylene witch is a composite material by filling graphite, molybdenum disulfide, carboform or the like material in nanometer formulation in the working face, the utility model has superior combination property congregated the advantages of two materials, solves the comfort feel when the elevator in running, and achieves ideal effect. The novel composite guide shoe has the advantages of lower friction, higher damping performance, and lower noisy, and improves the running quality of the elevator.

Description

The compound type guide shoe bush

Technical field

The utility model relates to the device that uses on a kind of elevator, the guide shoe bush that uses on particularly a kind of elevator.

Background technology

Leading boots is the direct parts of getting in touch between lift car and the guide rail, is the relative movement part of elevator.Therefore the performance quality of guide shoe bush directly has influence on the quality of the operational effect of elevator, because the operation characteristic of elevator self, require guide shoe bush must satisfy following characteristics: friction coefficient is low, and wear resisting property is good, and damping performance is good, and noise is low.The common material of leading the guide shoe bush of boots employing of elevator commonly used now generally has following several: nylon, polyurethane, High molecular weight polyethylene or the like.All there is certain defective in these materials because of the material behavior of self.As nylon and High molecular weight polyethylene friction coefficient still can, but because material is harder, make damping performance too poor, the operation noise is big; Though and the polyurethane material is softer and withstand voltage properties is better, but friction coefficient is too high again.These all directly cause the startup of elevator and running quality relatively poor.

The utility model content

The purpose of this utility model is: design the new type compound guide shoe bush of a kind of low frictional properties, high damping property, low noise, improve the running quality of elevator.

The utility model adopts following structure to realize above-mentioned purpose, design a kind of compound type guide shoe bush, this guide shoe bush is made up of damping matrix and driving surface, wherein damping matrix outside is embedded in and leads on the boots, in the damping matrix, post driving surface, between damping matrix and the driving surface lining cement is arranged, damping matrix adopting rubber, driving surface adopts the polytetrafluoroethylene of modification; What the rubber of damping matrix adopted is oil proof rubber.

Because its good damping performance of rubber is widely used in each industrial circle, adopting rubber here is exactly to utilize its good damping performance as basis material.What particularly adopt is to have the oil proof rubber of good oil resistant, excellent properties such as heat-resisting, acidproof, wear-resisting, ageing-resistant as the damping matrix.When satisfying shock attenuation needs, can adapt to the requirement of leading the boots working environment.

What driving surface adopted is the polytetrafluoroethylene of modification, this material is to fill graphite by the ultra-fine prescription of nanometer, molybdenum disulphide, the composite material that materials such as carbon fiber are made has very superior Combination property: high temperature resistant, low temperature resistant, withstanding corrosion, wear-resistant, friction coefficient is minimum, weather--the aging life-span of plastics the best is arranged.Place the field, it is also never rotten to be exposed to wind and rain, and high-insulativity, high-lubricity use as mechanical component and need not lubricant, do not adhere to any material.

Thereby the compound guide shoe bush of the utility model, with the sets of advantages of these two kinds of material materials together, make guide shoe bush well solve the operating comfort problem of elevator, operational effect is very desirable.

Description of drawings

The cross sectional drawing of Fig. 1 guide shoe bush;

The working state figure of Fig. 2 guide shoe bush;

Fig. 3 is that the A---A of Fig. 2 cuts open;

The outside drawing of Fig. 4 guide shoe bush.

The specific embodiment

As shown in Figures 1 to 4, compound type guide shoe bush 1 is made up of damping matrix 2 and driving surface 3, between damping matrix 2 and the driving surface 3 lining cement 4 is arranged, and damping matrix 2 adopts rubber, and driving surface 3 adopts the polytetrafluoroethylene of modification.What the rubber of damping matrix 2 adopted is oil proof rubber, better effects if.

Damping matrix outside is embedded in the whole shoe guide mount pad 5 during work, and the guide rail of elevator places in the driving surface, and slides in driving surface 3.

The shape of damping matrix 2 is not limit, and can take different shapes according to different shoe guide mount pads 5, is embedded in the whole shoe guide mount pad 5 all in this later-model protection domain as long as guarantee damping matrix 2 outsides.

As shown in Figure 2, lead boots and comprise: lead boots upper cover plate 6, lead boots base 7, lead the boots side and change plate 8, shoe guide mount pad 5, compound type guide shoe bush 1 is installed in the shoe guide mount pad 5.

Claims

1, a kind of compound type guide shoe bush, it is characterized in that: form by damping matrix and driving surface, wherein damping matrix outside is embedded in whole leading in the boots base, post driving surface in the damping matrix, between damping matrix and the driving surface lining cement is arranged, damping matrix adopting rubber, driving surface adopts the polytetrafluoroethylene of modification.

2, a kind of compound type guide shoe bush according to claim 1 is characterized in that: what the rubber of damping matrix adopted is oil proof rubber.
