Abstract
The invention relates to a high-strength nylon elevator pulley adopting monomer casting. The high-strength nylon elevator pulley is characterized by comprising an end surface and inner bearing snap rings, wherein the coaxial inner bearing snap rings are connected to the interior of the end surface through casting, and wiring grooves are formed in the outer surface of the end surface in a turning manner. The high-strength nylon elevator pulley adopting monomer casting is scientific and reasonable in structural design, has the advantages of steel wire rope protection, high safety, long service life, low maintenance cost, light weight, convenience in mounting and transportation and low probability of rusting, and has higher innovativeness.
Description
Technical field
The invention belongs to elevator accessory field, particularly a kind of high strength monomer cast nylon elevator rope sheave.
Background technology
Elevator rope pulley is the main drive disk assembly of elevator.Traditional elevator rope pulley is cast iron quality, and this material is comparatively serious to the wearing and tearing of steel rope, within average one to two year, will change once, and maintenance cost is larger.And the elevator rope pulley weight of cast iron is larger, inconvenient installation, maintenance and transportation.In addition, the elevator rope pulley of cast iron quality also easily gets rusty, and needs fitfull to maintain it.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of design science rationally, protection steel rope, long service life, maintenance cost is low, quality is light, convenient install and nylon elevator rope sheave is poured into a mould in transportation, the high strength monomer that is difficult for getting rusty.
The present invention solves its technical matters and takes following technical scheme to realize:
A monomer cast nylon elevator rope sheave, is characterized in that: end face and neck bearing snap ring, consist of, in the cast of the inside of end face, be connected with coaxial neck bearing snap ring, at the outside face of the described end face wire casing of having got on the bus.
And interval is cast with reinforced rib between described end face and neck bearing snap ring.
And the end face of described elevator rope pulley, neck bearing snap ring and reinforced rib are the integrative-structure that the cast of polycaprolactam monomer material forms.
Advantage of the present invention and good effect are:
1. this high strength monomer is poured into a mould nylon elevator rope sheave, by the elevator rope pulley of cast iron quality being before designed to apply the elevator rope pulley of new engineering material MC nylon (polycaprolactam monomer), utilize the premium properties of MC nylon self, improved the performance of whole elevator rope pulley.MC nylon elevator rope sheave self intensity is higher, can bear for a long time load; Its rebound resilience is good, can be crooked and indeformable, can keep toughness, opposing repeated stock simultaneously; Also there is wear-resistant self-lubricating, provide and be better than the serviceability of bronze cast iron rope sheave when without oil (or de-oiling) lubrication applications, reduced energy consumption, saved resource; This rope sheave can be inhaled noise, damping, and MC nylon modulus ratio metal is much smaller, large to the decay of vibrations; This material and Metal Phase ratio, its hardness is low, can not cause wearing and tearing to steel rope, plays a very good protection, and has improved the safety performance of elevator; Superior performance becomes simply the maintenance of rope sheave, has saved labour power; And its chemical inertness is higher, the corrosion of alkaline-resisting, alcohol, ether, hydro-carbon, weak acid, lubricating oil, washer solvent and seawater, and there is tasteless, nontoxic, rustless feature, extended the service life of rope sheave.
2. scientific structure design of the present invention is reasonable; there is protection steel rope, high safety, long service life, maintenance cost is low, quality is light, convenient install and transportation, be difficult for getting rusty, and is that a kind of high strength monomer with higher innovation is poured into a mould nylon elevator rope sheave.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the birds-eye view of Fig. 1.
Description of reference numerals:
1-end face, 2-neck bearing snap ring, 3-reinforced rib, 4-wire casing.
The specific embodiment
Below in conjunction with accompanying drawing, by specific embodiment, the invention will be further described.Following examples are descriptive, are not determinate, can not limit protection scope of the present invention with this.
A monomer cast nylon elevator rope sheave, its innovation is: end face 1 and neck bearing snap ring 2, consist of, in the cast of the inside of end face, be connected with coaxial neck bearing snap ring, at the outside face of the described end face wire casing 4 of having got on the bus.
Between described end face and neck bearing snap ring, interval is cast with reinforced rib 3.
The end face of described elevator rope pulley, neck bearing snap ring and reinforced rib are the integrative-structure that the cast of polycaprolactam monomer material forms.
During production, need to be under normal pressure, the raw material polycaprolactam monomer of melting is made to catalyst with alkaline material, then make together with the auxiliary agent such as activator and treat poly-monomer, and then be injected in the mould that is preheating to uniform temperature, make material in mould, carry out polymerization reaction, condense into tough and tensile solid embryo part, then pass through the processing of relevant technological, be processed into predetermined product, finally, then at the external peripheral surface of this predetermined prod get on the bus out for the wire casing of steel cable sliding.
Although disclose for the purpose of illustration embodiments of the invention and accompanying drawing, but it will be appreciated by those skilled in the art that: within not departing from the spirit and scope of the present invention and claims, various replacements, variation and modification are all possible, therefore, scope of the present invention is not limited to embodiment and the disclosed content of accompanying drawing.
Claims (3)
1. a high strength monomer cast nylon elevator rope sheave, is characterized in that: end face and neck bearing snap ring, consist of, in the cast of the inside of end face, be connected with coaxial neck bearing snap ring, at the outside face of the described end face wire casing of having got on the bus.
2. a kind of high strength monomer cast nylon elevator rope sheave according to claim 1, is characterized in that: between described end face and neck bearing snap ring, interval is cast with reinforced rib.
