Description

Elevator traction sheave

Technical field

The utility model relates to elevator accessory technical fields, more particularly to a kind of elevator traction sheave.

Background technique

Elevator is the riding tool that daily life frequently uses.But due to the particularity of its use occasion, need long-term It is maintained and replaces aging or wearing terrain in due course, to ensure the safety of elevator applications.

Traction sheave is the rope sheave on traction machine, also referred to as traction rope sheave or drive rope sheave, and traction sheave is elevator transmitting traction power Device, utilize the frictional force of rope groove on traction steel-cable and traction wheel rim to transmit power.Elevator, which can be divided into, computer room and inorganic Two kinds of room, the two is required to corresponding traction sheave.

Because traction sheave will bear the total weight of lift car self weight, load-carrying and counterweight, therefore spheroidal graphite casting is mostly used on material Iron, to guarantee that there is certain intensity and toughness.Meanwhile in order to reduce damage of the traction steel-cable in traction race, in addition to It selects outside reasonable traction sheave flute profile, certain regulation has been done to roughness, the hardness of the working surface of rope groove.

But in the prior art, traction sheave usually passes through bolt etc. in its side fixed gear plate, for carrying out the biography of power It passs, but traction sheave and the fixed of fluted disc need to keep firm, need to periodically be checked otherwise can there is great hidden danger, in addition, If distance is shorter between rope groove, it is be easy to cause the displacement of wirerope, equally there is biggish hidden danger.

Therefore, in view of the above technical problems, it is necessary to which a kind of elevator traction sheave is provided.
