Description
Technical field
The present invention relates to life test technical field, more particularly to a kind of elevator rope pulley sliding frictional wear life test
System and its method of testing.
Background technology
Traditional elevator traction system and speed limiter system is driven using traction sheave and governor sheave respectively, that is, is united
Referred to as elevator rope pulley.With steel wire rope continuous frictional when elevator rope pulley works, and the friction is largely for static friction and with few
The sliding friction of amount.When there is coating either chemical treatment layer on elevator rope pulley grooving surface or need to detect by encoder
In the case of the linear velocity of elevator rope pulley, the wear extent of elevator rope pulley grooving just needs to assess.Assess elevator rope pulley grooving and steel
The wear-out life of cord, for the structure of design elevator rope pulley grooving, selection and the performance of elevator rope pulley is assessed with very
Important meaning.
It is reported that unspecial at present test rope sheave and the equipment in steel rope abrasion life-span.Some elevator rope pulleys and steel
Cord endurance testing device, using the method for steel wire rope and elevator rope pulley static friction come the actual condition of simulating elevator running, mesh
Preceding conventional method has following two：1) rope sheave is movable pulley, using certain method driving steel wire rope movement, steel wire rope and rope
The stiction driving rope sheave rotation of wheel；2) rope sheave is movable pulley, and steel wire rope be may move, and rope sheave is fixed in frame, passes through machine
The rotation of frame, drive and static friction occurs between rope sheave and steel wire rope.Life test is carried out using static friction, its advantage is to compare to connect
Nearly actual condition, but shortcoming is that the required testing time is very long, needs continuous 24h uninterruptedly operating more than 1 year under normal circumstances
Time could complete the reliable test to elevator rope pulley, so require that shorter and shorter technology trends come for the design cycle
Say, this kind of life approach obviously has significant limitation.
Between this, also occurs a kind of traction-driven friction testing arrangement on the market.The equipment drives traction by motor
Machine is slowly rotated, and after steel wire rope bypasses traction sheave, is connected with spring and pulling force sensor, and spring fastening is led to by Driven by Hydraulic Cylinder
Cross hydraulic cylinder and tension force is produced to steel wire rope.Although the test device can be tested out between confficient of static friction and the coefficient of kinetic friction
Relation, but there is also some limitations for the test device：1) long-time life test can not be carried out.Steel wire rope and traction sheave rub
It is immutable to wipe section, if long-play, inevitably results in same section of steel wire rope and is dry grinded with traction sheave, be not equal to reality completely
Border operating mode, and can cause and drastically wear；2) do not have the condition of life test.Do not record the run time related to the life-span,
The equipment such as number of run；3) it is effective for PVvalue testing, but the wear data of traction sheave and steel wire rope can not be tested.
