Description
Technical field
The utility model relates to a kind of nylon rope wheel apparatus.
Background technology
The traditional rope sheave of elevator is generally cast steel or cast iron quality, is press-fitted after being press-fitted or taking turns heating with bearing normal temperature by wheel, through the design of third wheel assembling endoporus tolerance, can ensure to be press-fitted trailing wheel and outside race is interference fit, to ensure the precision of use.Then bearing assembles with axle again.Because wheel is identical with the linear thermal expansion coefficient of the material of bearing use, ensure that in use afterwards, both assembly relations can not change because of the temperature traverse of environment for use.Then take turns in the grooving of outer ring hoist ropes must be installed, because wheel belongs to metallic sheave, and dragging rope for elevator uses steel rope according to GB regulation, and metallic sheave and steel rope abrasion are very severe, have a strong impact on the service life of expensive steel rope, and the safe handling of equipment is constituted a threat to.
Under existing technology, develop at present alternative current cast steel, the cast iron matter rope sheave of nylon wheel with the direct pouring of MC nylon material, the point that hard steel pulley is rigidity with steel rope in the ordinary course of things contacts, there is very high contact part and steel rope is is easily worn and torn, while use even in the early stage, just likely cut off steel rope, nylon wheel is softer than steel pulley, easily slides, while contact with steel rope, there is certain distortion, thereby be elastomeric with steel rope and contact.This declines maximum contact pressure, and wearing and tearing reduce, and service life of steel wire rope extends.This kind of nylon wheel is directly press-fitted with bearing, ensures precision and the use of installation by the interference fit of nylon wheel and bearing.
But the linear expansion factor of MC nylon is 6.0 ~ 8.3 × 10
-5, and the linear expansion factor of bearing steel is 1.12 × 10
-5.Both differ 5.35 ~ 7.4 times of left and right.And the environment for use of elevator is very complicated, the ambient temperature that elevator uses may be between-30 DEG C ~ 50 DEG C scopes, between MC nylon wheel and bearing, because will causing, the variation of temperature coordinated pine while raising (temperature) or tension (when temperature reduces) between the two: in the time coordinating the amount in gap of pine and generation to be greater than to assemble when the magnitude of interference of bearing and nylon wheel, nylon wheel will and bearing between produce excessively to coordinate and cause both temperature arrising caused by friction, simultaneously because the space between bearing and nylon wheel endoporus is less, fricative heat is difficult for dissipating and will directly accelerates the wearing and tearing of bearing and nylon wheel, finally cause both no longer to mate.This unmatched the possibility of result be bearing be in operation produce noise and make elevator be in operation produce vibration or rock, affect the quality of elevator; In the time that temperature reduces cooperation tension, the deflection of nylon wheel is greater than bearing, thereby make coordinating along with the reduction of temperature is more and more tighter of nylon wheel and bearing, reduce normal play between the two, in the course of time will damage bearing, elevator is in operation and produces noise and vibration, affect the quality of elevator.
Through the retrieval of prior art is found, China Patent No. is 200620075985.5, name is called " Mixed Type Lift Diversion Sheave And Guide Pulley ", this technology readme: Mixed Type Lift Diversion Sheave And Guide Pulley is provided with cast-iron core wheel and nylon engineering plastic foreign steamer, nylon engineering plastic foreign steamer is fixedly installed on cast-iron core wheel, cast-iron core wheel is provided with bearing hole, nylon engineering plastic foreign steamer is provided with traction grooving, the concaveconvex structure that is provided with mutual coupling engagement between cast-iron core wheel and nylon engineering plastic foreign steamer, cast-iron core wheel is provided with louvre.But this prior art can not dynamically be adjusted the play between track adjusting wheel and bearing in the time of track adjusting wheel temperature change, be therefore difficult to guarantee that bearing normally works, affect quality and the service life of elevator.And this prior art can not avoid the incompatible type problem of cast-iron core wheel and nylon engineering plastic two kinds of unlike materials in the time of unit-cast unit, these two kinds of materials itself are just difficult to fit together.
Utility model content
The purpose of this utility model is to overcome deficiency of the prior art, and nylon rope sheave, nylon rope wheel apparatus and assembly method and the elevator containing rope pulley device are provided, and can reduce assembling link, promotes riding quality.
The utility model is achieved through the following technical solutions, and the utility model comprises:
Comprise sheave shaft, bearing, nylon rope sheave and steel rope, described sheave shaft coordinates with special bearing, described special bearing and nylon rope sheave coaxial sleeve connect, on described nylon rope sheave, be provided with the wire casing for described steel rope is installed, also comprise the torsional pin that forms revolute pair with nylon rope sheave and special bearing, on described nylon rope sheave madial wall, be evenly equipped with at least 1 the first grooving, on described special bearing lateral wall, be also evenly equipped with at least 1 the second grooving with the first grooving corresponding position of described nylon rope sheave, in the cavity that described the first grooving and the second grooving form, be provided with torsional pin, the cross-sectional plane of described the first grooving and the second grooving is cydariform, square or circular.
Further, described torsional pin be shaped as cydariform, square or circular, described torsional pin is made up of metal or non-metal.
Compared with prior art, nylon rope wheel apparatus operation of the present utility model is more steady, reliable, and can transmitting large torque.Reduce the requirement that nylon rope sheave and special bearing are press-fitted, reduced assembly error, reduced cost, promoted quality.
The utility model also provides the assembly method of this nylon rope wheel apparatus, first torsional pin is installed on special bearing lateral wall, then adopts slight interference to coordinate installation nylon rope sheave and special bearing, finally sheave shaft is coordinated with special bearing.
If temperature reduces; because the deflection of nylon rope sheave is greater than bearing; coordinating more and more tighter the reduction along with temperature of nylon rope sheave and special bearing; the matching relationship of nylon rope sheave and special bearing is to become better and better; and during due to assembling, nylon rope sheave coordinates with the slight interference that special bearing adopts, and under the ambient temperature of-30 DEG C, the play reduction of special bearing will be very little; both protect special bearing, ensured again the quality of elevator.
