Special MC (Methyl Cellulose) nylon wheel for combined oilfield

Abstract

The invention discloses a special MC (Methyl Cellulose) nylon wheel for a combined oilfield and belongs to the technical field of a nylon product. The special MC nylon wheel comprises MC nylon wheel bodies made of MC nylon, rigid bushing blocks and a wheel axle. 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 [0001] The invention relates to a composite MC nylon wheel, in particular to the mechanism of an oilfield-specific MC nylon wheel, and belongs to the technical field of nylon products. Background technique [0002] In the oilfield machinery industry, more than 80% of the gear trains are operated in the open air. Now a large number of cast iron materials are used to make the pulley body, which is heavy and easy to rust. The wheel body directly contacts the wire rope, which reduces the service life of the wire rope and makes it difficult to replace. big. Due to the light weight of MC nylon material, it has the advantages of self-lubrication and good chemical stability, so it does not need to be refueled, easy to replace, protects the wire rope, and prolongs the service life of the wire rope; Adverse effects, such as accelerating the wear of the wire rope and itself, affect the transmission accuracy and service life. For this reason, relevant technical personn...

Problems solved by technology

Due to the light weight of MC nylon material, it has the advantages of self-lubrication and good chemical stability, so it does not need to be refueled, easy to replace, protects the steel wire rope, and prolongs the service life of the steel wire rope; while the cast iron wheel is produced by the steel wire rope and the overall movement mechanism. Adverse effects, such as accelerating the wear of the wire rope and itself, affecting the transmission accuracy and service life

For this reason, relevant scientific and technical personnel have developed MC nylon wheels required in related fields. However, for oil field machinery operating in the open air outdoors, the working environment is harsh, and the existing MC nylon wheels cannot meet the needs.
