the application of powder metallurgy gear

The powder metallurgy parts in automobile, motorcycle proportion rising, is one of the most widely used powder metallurgical gears.Whether by weight or by the number of parts, powder metallurgy in automobile, motorcycle gear proportion are is far greater than any other in the field of powder metallurgy parts.Therefore, from automobiles and motorcycles in the proportion of powder metallurgy parts increases as you can see, powder metallurgy gear in the powder metallurgy parts in a position of rapid development.If the component characteristics, belongs to structural parts, gear and structural parts in the entire iron base parts of absolute weight also is far greater than other categories of powder metallurgy parts.

The Advantages of Powder Metallurgy Gear

The advantages of powder metallurgy gear:

1.low cost, high efficiency, molding in one time, no need to process tooth after forming.

2.due to its processing properties, powder metallurgy can make oil-bearing parts, forming free lubrication parts, but some are worse than oil bath lubrication, belong to boundary lubrication.

3.No waste in gear forming process, one of the best of resource utilization for the steel.

Profile accuracy of powder metallurgy

ZCMIM is one of the largest domestic Hangzhou powder metallurgy gear production, with the advanced machinery and equipment, strong technical force and achieved leading position in technology and quality, are sold throughout the country and overseas market. Following the presentation of a powder metallurgy gear tooth profile precision:

Tooth profile accuracy of powder metallurgy gear without finishing:

1 sintered gear tooth profile accuracy can be controlled at the JIS6 level (the old standard).

2 heat treatment gear tooth profile accuracy can be controlled at the JIS7 level (the old standard).

After finishing the gear, the tooth profile accuracy will be greatly improved:

1 sintered state precision can be controlled at the JIS4~5 level (the old standard).

2 heat treatment state precision can be controlled in the shape of the JIS6 level (the old standard)

What is the basis for the design of powder metallurgy gear?

To help customers understand the characteristics of powder metallurgy gear, deepen the understanding between the two sides, to facilitate communication between the two sides, as follows:

Powder metallurgy gear material:

1. Powder metallurgy gear material is suitable for standard of powder metallurgical materials, powder metallurgy materials have a variety of materials standard. Most countries and some large companies have their own standards, due to the fact that Japan and the United States in Powder Metallurgy Research walk in the forefront of the world, so the widely adopted standards of materials used is JIS (Japanese), the MPIF (USA) two standards.

2. Gear usually on strength have certain requirements, so the selection of materials for better performance, over a wide range of materials used in the gear is Fe-Cu-C-Ni materials. (the meet JIS SMF5030, SMF5040; comply with the MPIF FN-0205, FN-0205-80HT); manufacturers to choose the Cu, Fe-Cu-C material.

Powder metallurgy gear and reduction gear box is how to work it?

Powder metallurgy can make the gear carrier, the gear, including gear body, in gear inside the body of the week is provided with a gear and full of inner circumference of the gear body and the gear on the outside of the set has at least six positioning block; and speed reduction gear box gear provided by the utility model can and other supporting components fast and convenient for fixing, clamping, so as to improve the stability of the gear mechanism, and because of the gear is through the metal powder pressed into a shape, to avoid the trouble artificial or stamping forging process, and more suitable for mass production and high efficiency.

Special lubricant for powder metallurgy gear

With the development of industrial automation, the powder metallurgy products industry developed rapidly, and the application field is no longer confined to the mechanical equipment industry. Today, Chaodeng in place, also often see powder metallurgy products, technology products, such as ceramic production. Powder metallurgy products have been widely used in all walks of life.

Prospects for the development of powder metallurgy industry in recent years, through the continuous introduction of foreign advanced technology and independent innovation combined, powder metallurgy industry and technology of China presents the rapid development trend, industry one of the fastest growing parts of China general machinery industry, every year, the powder metallurgy industry output value to 35% speed increase.

The global manufacturing industry is accelerating the transfer to China, the rapid development of automobile industry, machinery manufacturing, metal industry, aerospace, instrumentation, hardware tools, construction machinery, electronic appliances and high-tech industries such as, for the powder metallurgy industry brought rare development opportunity and huge market space. In addition, the powder metallurgy industry has been included in the priority development and encourage foreign investment projects, the development prospects are broad.

Powder metallurgy hydraulic press is designed for foundry and scrap metal processing. This machine is suitable for powder and granular cast iron, copper scrap, steel scrap and other scrap metal cold pressed cake into a cylindrical furnace using direct investment. The machine has a high degree of automation, which can reduce the waste of materials and improve the productivity of the users.

This machine adopts the advanced machine, electricity, liquid, gas integration control, with automatic feed feeding device, floating pressing, effectively control the density of molding, demoulding and general release protection etc. to choose from, the hydraulic system using advanced combination of valve block, ensure liquid continuous press, frequent stable work; three filling, shaping, demoulding position mechanical gear positioning block and stepless adjusting mechanism to determine the geometric dimension of the product is stable and adjustable. Oil cooling device. The use of PLC and man-machine interface centralized control, and equipped with mechanical limit device, so as to ensure the consistency of products.

With the development of the market, the factory must rely on advanced technology and good management to win the competition in the market. We will with our strong technical strength, keep the spirit of innovation, excellent product quality, perfect after-sales service to our customers and friends to provide high quality and low price of high-tech products, for the factory to win a broad market space for survival.
