Description
Technical field
The present invention relates to a kind of traction wheel constructions, are applied to elevator traction sheave field.
Background technology
Traction sheave is the critical component on elevator traction machine, and the traction of traction wheel drive elevator operation is to rely on hoist ropes
Frictional force generates between (band) and traction sheave grooving (or traction wheel surface), and shape, the state on traction sheave grooving and surface become
Change, it will be directly related to the service life of the size and hoist ropes (band) of traction, quality directly affects the safety of traction
Performance and used life.
It is to determine that traction is driven since traction sheave is the whole Dynamic And Static Loads for carrying the devices such as lift car, loading capacity, counterweight
The source of dynamic system and complete machine function, therefore big intensity, good toughness, wear-resistant, impact resistance and stabilization are required to traction sheave
The material and structure of the performances such as friction.However, existing elevator with traction sheave using metal casting or metal component by surface at
Reason is formed, and the friction coefficient between metal and hoist ropes is relatively-stationary, only by being processed into type groove or improving hoist ropes
The friction of (band) improves equlvalent coefficient of friction, or by increase traction wheel diameter or wirerope diameter (or traction bandwidth) come
Contact strength and hoist ropes (band) service life are improved, to meet traction life requirements, by different lift cars, loading capacity, right
Equal configurations meet tractive driving ability again.But the service life that equlvalent coefficient of friction is improved by groove profile is limited, is also the failure to obtain
Larger friction coefficient is obtained, it is real that safety and service life, reduction system cost of complete machine etc. can not be improved from tractive driving system
Sex chromosome mosaicism.
On the other hand since hoist ropes (band) tension is inconsistent, it be easy to cause grooving (or contact surface of drawing belt) abrasion not
Unanimously, there is unnecessary serious uneven wear phenomenon, to change flute profile, seriously affect hoist ropes (band) service life and drag
Gravitation carrys out larger security risk to elevator belt.In existing elevator actual motion, the abrasion of hoist ropes (band) is very big, 5 years average
It needs replacing once, this makes cost further increase.
Therefore, the equlvalent coefficient of friction for how inherently improving traction sheave rooved face, with improve wear resistance, intensity and
The problem of comprehensive performances such as toughness reduce steel wire and traction wheel diameter, are elevator traction sheave field urgent need to resolve.
