Abstract
A titanium steel composite elevator traction wheel comprises a rim, spokes and a shaft sheath, and adopts the technical points that the rim adopts a titanium steel composite structure, a traction rope slot is formed in the outer side of the titanium alloy layer of the rim, and the rim are welded together with the spokes through the carbon steel layer of the rim; each spoke adopts a sandwich structure comprising a spoke carbon steel layer, a spoke foam aluminum layer and another spoke carbon steel layer; the shaft sheath is welded together with the spokes. The traction wheel provided by the invention fundamentally solves the problems that the traction force of a half slot traction wheel is low due to the low friction coefficient of the carbon steel material of a high speed elevator traction wheel and the limitations from a V-shaped slot traction wheel are high. Moreover, the titanium steel composite elevator traction wheel provided by the invention adopts a composite structure, is light in weight and has wave absorbing and shock absorbing functions.
Description
Technical field
The present invention relates to a kind of weight-lifting equipment technical field, specifically a kind of
titanium steel is compoundelevator traction sheave and production method thereof.
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, V-shaped groove can only be used for underloading, slower elevators conventionally.
Therefore need a kind of friction coefficient elevator traction sheave, the defects such as above-mentioned half slot traction sheave traction is low to overcome, V-shaped groove traction sheave limitation height.
