Information

Shandong Zhengxiang Industrial and Mining Equipment Co., Ltd. is a professional non-ferrous metal processing and casting manufacturers, the company mass production of boring machine copper sleeve, copper worm gear. Because most of the boring machinery in high temperature, dust, heavy load and heavy pressure conditions continue to work, so the accessories should meet the requirements of high efficiency, reliability, safety, durability and energy saving.

 

Copper sleeves, also known as copper bearings, are used in sliding rotating machinery to reduce friction and at the same time to drive thrust and support fixed parts. Copper sleeve to lubricate bearing. Copper sleeve is also made of various copper alloys for lubrication of mechanical parts. Copper sleeve is mainly used for body part and walking mechanism on the roadheader.

 

A boring machine is a machine used to cut straight underground tunnels. Roadheader is divided into open roadheader and shield roadheader. It is mainly composed of body part, walking mechanism (available to copper sleeve), working mechanism, loading mechanism and transfer mechanism. As the walking mechanism advances, the cutting head in the working mechanism continuously breaks the rock and carries the broken rock away. It has the advantages of safety, high efficiency and good quality of roadway formation.

 

Body part copper sleeve: body part is located in the middle of the body, with high strength thick steel plate as the main material welded box structure, body part in front of the upper part of the rotary table, rotary table is used for vertical and horizontal movement of the cutting part, it is connected with the body frame with rotary bearings, and hinged out of the shaft sleeve all use copper sleeve, convenient disassembly and assembly.

 

Because most of the boring machinery is constantly working under high temperature, dust, heavy load and heavy weight, so the accessories should meet the requirements of high efficiency, reliability, safety, durability and energy saving. Among copper base alloys, aluminum bronze is more in line with the requirements. The aluminum content of aluminum bronze jacket is generally less than 11.5%, and sometimes appropriate iron, nickel, manganese and other elements are added to further improve the performance. Aluminum bronze copper sleeve can be strengthened by heat treatment, its strength is higher than tin bronze copper sleeve, high temperature oxidation resistance is also better.

 

Aluminum bronze copper sleeve containing iron and manganese elements has high strength and wear resistance, after quenching and tempering can improve the hardness, has good high temperature corrosion resistance and oxidation resistance, in the atmosphere, fresh water and seawater corrosion resistance is very good, machinable, welding is not easy to fiber welding, hot pressure processing good.

 

Aluminum bronze has good cutting and grinding properties, can be welded, and is easy to be formed by hot working. Alloy is mainly used in the manufacture of bracket, gear, copper sleeve, bushing, nozzle, flange, rocker arm, pilot valve, pump rod, CAM, fixed nut and other high strength and wear-resistant structural parts. With high strength and wear resistance, widely used in high-voltage electrical appliances, Marine industry, after quenching and tempering treatment can further improve the strength, wear resistance and oxygen resistance.

 

Our company produces a variety of specifications and materials of large copper sleeve, sliding bearings, rolling bearings, bushing, bearing, copper nut, copper slide, copper worm gear strong technical force, rich production experience, stable and reliable quality, good faith management, always for the sake of customers, welcome friends from all walks of life to negotiate guidance.
