| Abstract: | To introduce elevator working principle,the causes of wire rope slip on elevator traction pulley are analyzed.According to GB/T 7588—2003 The Safety Specification for Elevator Manufacture and Installation to introduce the system traction capability demands and the formula of equivalent friction factor.Combining practical example to calculate elevator system traction capability and verifying on the conditions of lift car loading,emergency braking and lift car stop,the effects of factors such as balance efficiency,lift car mass,lift car rise height,compensation chain(rope) mass,wrap angle of rope on pulley,elevator running speed,traction wire rope tension uneven,system acceleration,traction pulley depth error or abrasion,lubrication,on traction capability of elevator system are analyzed.Measures to avoid wire rope slip are given. |
| Keywords: | elevator traction wire rope slip traction capability equivalent friction fator balance coefficient lubrication |
