Shown in Figure 13, the embodiment is the rearmounted winding of steel wire rope, and foregoing is all the left and right sides direction of car, the reality
The rear direction that example is car is applied, shaft width is too narrow, a kind of arrangement of shaft depth.
Traction elevator：Power reason principle is that by way of frictional force lifts car, it is anti-that method of operation car rises counterweight
Direction declines.According to Euler's formula；T1 is that the pulling force of cage side, T2 are that the pulling force of counterweight-side, e are natural logrithm, f
It is cornerite for coefficient of friction, a.
The structure critical piece of traction elevator is car, counterweight, traction machine, steel wire rope.Pass through cage side T1 and counterweight
The logarithm value of the T2 ratios of side, contrast cornerite and coefficient of friction.
IfThen illustrate that steel wire rope is non-slip in main frame double wrap sheave 1, normally lift car；
IfThen illustrate that steel wire rope skids in main frame double wrap sheave, it is impossible to normally lift car.
Therefore deduce that, traction elevator must have T2 to gravity, a cornerite is generally higher than 150 °.
Elevator is driven from traction：Power reason principle is also to lift car by frictional force, by the complementary winding of steel wire rope,
And cancel the design method of counterweight.According to Euler's formula,The car of T1 sides is constant, and T2 sides counterweight is cancelled by part 9
Tension pulley replaces.Because the pulling force of tension pulley is less than counterweight, making T1/T2 ratio increases.In order to ensure traction, by efa
Middle a cornerites increase, by individual pen, increase to the method cornerites of the multi-turns such as 2 circles, 3 circles, 4 circles, 5 circles is increased to for 150 ° by traction-type
270 °, 450 °, 630 °, 810 ° etc., the same ratio for ensureing T1/T2 is less than efa, make steel wire rope non-slip in main frame double wrap sheave,
Normally lift car.
Above-described is only preferred embodiment of the present utility model, it is noted that for the ordinary skill of this area
For personnel, on the premise of the utility model creation design is not departed from, various modifications and improvements can be made, these all belong to
In protection domain of the present utility model.
