The special MC nylon wheel is characterized in that the MC nylon wheel body at least comprises two rigid bushing blocks which are connected in concentric bushing; a bolt is used for fixedly connecting two adjacent MC nylon wheel bodies; the rigid bushing blocks are arranged on the wheel axle by a bearing; the inner walls of the two ends of the rigid bushing blocks are respectively provided with annular grooves for supporting the bearings; the bearings are supported in the annular grooves; the two ends of the MC nylon wheel are provided with locking dust-prevention end covers for covering the rigid bushing blocks and the bearings, and the locking dust-prevention end covers are respectively and fixedly connected with the MC nylon wheel bodies and the rigid bushing blocks through the bolts. The special MC nylon wheel for the combined oilfield is simple and reasonable in structure, easy to product and low in cost. With the adoption of the special MC nylon wheel for the combined oilfield in oilfield machinery industries, corrosion, noise and large abrasion produced by the contact of a cast iron and a steel wire rope are avoided, and the service life of the steel wire rope is prolonged.
Description
Technical field
The present invention relates to a kind of compound MC nylon wheel, especially the mechanism of the special-purpose MC nylon wheel in oil field, belongs to nylon products technical field.
Background technique
In oilfield machinery industry, train more than 80% is in outdoor open work, and the existing a large amount of cast iron materials that adopt are made pulley body, and quality weigh, easily gets rusty, wheel body directly contacts with wire rope, has reduced the working life of wire rope, and replacing difficulty is large.Due to MC nylon material light weight, possess self lubricity, good chemical stability, therefore, without refueling, change conveniently, wire rope being shielded, extend the working life of wire rope simultaneously; And the harmful effect of cast-iron wheel to wire rope and the generation of mass motion mechanism, as accelerated wire rope and the wearing and tearing of self, affects transmission precision and working life.For this reason, relevant scientific and technical personnel have researched and developed the needed MC nylon wheel of association area, still, for the oilfield machinery in outdoor open work, work under bad environment, existing MC nylon wheel can not be satisfied the demand.So, in oilfield machinery operation, be badly in need of a kind of light weight, non-corrosive, self lubricity good, rational in infrastructure, adapt to the outdoor open work environment in oil field, the special-purpose MC nylon wheel in oil field of long service life.
Summary of the invention
Object of the present invention is exactly for meeting the needs in market, provide a kind of light weight, non-corrosive, self lubricity good, rational in infrastructure, adapt to the outdoor open work environment in oil field, and can extend wire rope and motion working life, improve the special-purpose MC nylon wheel in combined type oil field of transmission precision.
The object of the invention is to be achieved through the following technical solutions, the special-purpose MC nylon wheel in combined type oil field, comprise the MC nylon wheel body of being made by MC nylon, rigidity lining, wheel shaft, it is characterized in that, described MC nylon wheel body is at least two and inlays with one heart cover connection by rigidity lining, between two adjacent MC nylon wheel bodys, being also provided with bolt is connected and fixed, rigidity lining is arranged on wheel shaft by bearing, the two ends inwall of described rigidity lining is respectively equipped with the annular groove of block bearing, bearing is bearing in annular groove, the two ends of described MC nylon wheel are provided with the dustproof end cap of locking that covers rigidity lining and bearing, the dustproof end cap of locking is connected and fixed with MC nylon wheel body and rigidity lining respectively by bolt, the even interlaced arrangement of bolt difference that is connected and fixed the bolt of the dustproof end cap of locking and MC nylon wheel body and is connected and fixed the dustproof end cap of locking and rigidity lining is interior, on outer two circumference, the bolt that is connected and fixed the dustproof end cap of locking and MC nylon wheel body is evenly arranged on excircle, the bolt that is connected and fixed the dustproof end cap of locking and rigidity lining is evenly arranged on inner circumference.
The axle hole that provides wheel shaft to wear installation is provided the dustproof end cap of described locking, and corresponding described bearing place is provided with the boss that withstands bearing outer ring inside the dustproof end cap of locking, and boss withstands bearing outer ring outside.
Described wheel shaft is provided with the shaft shoulder, and the shaft shoulder withstands bearing inner race inner side.
The present invention is rational in infrastructure simple, manufactures easily, and cost is low.By MC nylon, made two or many MC nylon wheel bodys adopt and are connected with the rigidity lining of the concentric setting of wheel body, be also provided with bolt and be connected and fixed between two adjacent MC nylon wheel bodys.The dustproof end cap of locking is connected and fixed with MC nylon wheel body and rigidity lining respectively by bolt, the even interlaced arrangement of bolt difference that is connected and fixed the bolt of the dustproof end cap of locking and MC nylon wheel body and is connected and fixed the dustproof end cap of locking and rigidity lining is on inside and outside two circumference, the bolt that is connected and fixed the dustproof end cap of locking and MC nylon wheel body is evenly arranged on excircle, the bolt that is connected and fixed the dustproof end cap of locking and rigidity lining is evenly arranged on inner circumference, improves MC nylon wheel body and rigidity lining join strength.The installation location of bearing adopts: the two ends inwall of rigidity lining is established respectively annular groove, bearing position as block bearing, bearing is bearing in annular groove, and corresponding described bearing place is provided with the boss that withstands bearing outer ring inside the dustproof end cap of locking, and boss withstands bearing outer ring outside.On wheel shaft, establish the shaft shoulder, the shaft shoulder withstands bearing inner race inner side, guarantees that bearing is installed positioning stablity reliable, dustproof, rainproof, increases the service life.
In oilfield machinery industry, the cast-iron wheel of former employing is used instead to the special-purpose MC nylon wheel in combined type of the present invention oil field, avoid cast-iron wheel to contact with wire rope and produce compared with galling and noise, overcome the harmful effect that cast-iron wheel produces corrosion and wire rope is produced in outdoor outdoor situation, improve the working life of wire rope; Reduce labor intensity is installed, raise the efficiency; Reduce rate of fault and the turnover rate of overall operation mechanism.The special-purpose MC nylon wheel in combined type oil field, can also be applicable in the machineries such as mine, harbour.
