Abstract
The utility model discloses a traction sheave of titanium steel composite elevator. The traction sheave comprises a rim provided with a hoisting rope slot, a spoke and a shaft sleeve. The technical essential is that the rim is of a titanium steel composite structure, the hoisting rope slot is arranged outside a titanium alloy layer of the rim, and the rim and the spoke are welded through a carbon steel layer of the rim; the spoke is of a sandwich structure consisting of a carbon steel of the spoke, a foamed aluminum layer of the spoke and a carbon steel layer of the spoke; the shaft sleeve and the spoke are welded. Therefore, the problems that low traction force of the traction sheave of a semicircular slot, high limitation of the traction wheel of a V-shaped slot and others caused by low friction coefficients of carbon steel of the traction sheave of a high-speed elevator can be essentially solved; meanwhile, the titanium steel composite traction sheave has the effects of light weight, wave absorbing and shock absorption.
Description
Technical field
The utility model relates to a kind of weight-lifting equipment technical field, specifically a kind of titanium steel composite elevator traction sheave.
Background technology
Traction sheave is the rope sheave on the towing machine of elevator, also claims the rope sheave that drives of traction rope sheave or elevator, is the device that elevator transmits traction power, utilizes the friction force transferring power of grooving on the traction steel-cable of elevator and traction wheel rim.Existing traction sheave adopts spheroidal graphite iron manufacture conventionally, and it is to be produced by the friction force between hoist ropes and traction sheave grooving that traction sheave drives the traction of elevator operation, and therefore the shape of traction sheave grooving is directly connected to the size of traction and the life-span of hoist ropes.The shape of traction sheave grooving comprises half slot, nicked half slot (claiming again Baltimore groove), V-shaped groove etc.
Wherein, half slot and hoist ropes area of contact are large, and hoist ropes deformation is little, are conducive to extend hoist ropes and traction sheave life-span.But the equlvalent coefficient of friction of half slot grooving is little, and traction is low, in order to improve pulling ability, must use the method for after-combustion hoist ropes, to increase the cornerite of hoist ropes on traction sheave, it is multiplex entirely in formula high-speed tractive machine without gear wheel DC elevator.Half slot is also widely used in track adjusting wheel, crosshead sheave, grooving to roller.
V-shaped groove both sides produce very large squeese pressure to hoist ropes, hoist ropes and V-shaped groove area of contact are little, and the unit pressure (specific pressure) of contact surface is large, and hoist ropes deformation is large, between hoist ropes and V-shaped groove, there is higher equlvalent coefficient of friction, can obtain very large propulsive effort.But the flute profile of this grooving and the wearing and tearing of hoist ropes are very fast, and V-shaped groove wearing and tearing will cause hoist ropes center to move down, and flute profile approaches nicked half slot, and equlvalent coefficient of friction declines to a great extent.
Therefore need a kind of elevator traction sheave of great friction coefficient, the defects such as above-mentioned half slot traction sheave traction is low to overcome, V-shaped groove traction sheave limitation height.
Utility model content
The purpose of this utility model is to provide a kind of titanium steel composite elevator traction sheave, has fundamentally solved the problems referred to above.
The purpose of this utility model is achieved in that this titanium steel composite elevator traction sheave comprises wheel rim, spoke, the axle sleeve with traction grooving, its technical essential is: described wheel rim is titanium steel composite structure, traction grooving is arranged on the outside of wheel rim titanium alloy layer, and wheel rim is by wheel rim carbon steel layer and spoke welding; Spoke is the sandwich construction that carbon steel-foamed aluminium-carbon steel forms; Axle sleeve and spoke welding.
Described traction grooving is half slot or Baltimore groove or V-shaped groove.
The advantage the utlity model has and positive technique effect are: wheel rim adopts titanium steel composite material, and the coefficient of static friction of the grooving on titanium matrix and steel rope friction pair is 0.3, and spheroidal graphite iron and steel rope friction pair coefficient of static friction are 0.1.Titanium matrix and steel rope friction pair are spheroidal graphite iron and steel rope friction pair 2 ~ 3 times, have increased equlvalent coefficient of friction.Can adopt half slot, large with hoist ropes area of contact, hoist ropes deformation is little, is conducive to extend hoist ropes and traction sheave life-span, thereby improves the safety factor of elevator.The coefficient of static friction of titanium and titanium is 6.5 left and right, if the hauling rope that coupling titanium silk material is made can further promote safety factor.Adopt various metals composite structure to manufacture elevator traction sheave, wheel cause titanium steel composite material is made, and than spheroidal graphite iron loss of weight 30%, has good resistance to abrasion simultaneously.The sandwich construction that spoke adopts carbon steel sheet and foamed aluminium composite material to make, had both had high strength, had alleviated again weight.Also there is good antidamping, improved damping performance, thereby improved product design.In sum, that traction sheave of the present utility model has is lightweight, friction coefficient is large, damping performance good, long service life, and the advantages such as good reliability, can significantly improve safety factor.
Brief description of the drawings
Below in conjunction with accompanying drawing, the utility model is further described.
Description of reference numerals: 1 wheel rim titanium alloy layer, 2 wheel rim carbon steel layers, 3 spoke foamed aluminium layer, 4 spoke carbon steel layers, 5 wheel cases.
