Talking about several failures of gears

When we use gears in our life, we often encounter the situation of gear failure, so in what environment is the gear more prone to failure, today we will talk about several methods of gear failure. 1. Failure due to fatigue pitting Since the gears are always in cyclic motion, and the orientation of the meshing point is constantly changing, under the effect of long-term force, small cracks will gradually appear at the knife marks on the tooth surface. When it is long, the cracks will increase, which will constitute the phenomenon of fatigue pitting. 2. Failure due to plastic deformation of the tooth surface. The so-called plastic deformation is the deformation of the curved surface of the tooth profile. This situation is generally due to the overloading of the mechanism.

Pulley manufacturers: Introduce pulleys for you

Pulley manufacturers: Introduce pulleys for you

The pulley belongs to the hub type parts, generally the relative size is relatively large, and the manufacturing process is mainly casting and forging. Generally, the larger size design is casting, and the material is generally cast iron (good casting performance), and rarely cast steel (steel has poor casting performance); generally, the smaller size can be designed as a forging, and the material is steel. Pulleys are mainly used for long-distance power transmission occasions, such as the power output of small diesel engines, agricultural vehicles, tractors, automobiles, mining machinery, machining equipment, textile machinery, packaging machinery, lathes, forging presses, and some small horsepower motorcycles. Transmission, power transmission of agricultural machinery, air compressors, reducers,

Some knowledge points of powder injection, MIM powder injection manufacturers tell you

MIM powder injection manufacturers believe that metal powder injection molding technology is a multidisciplinary product of plastic molding technology, polymer chemistry, powder metallurgy technology and metal material science. Using mold injection molding blanks to quickly and accurately materialize high-density, high-precision, three-dimensional complex-shaped structural parts into products with certain structural and functional characteristics, and directly mass-produce them, is a new revolution in the manufacturing technology industry. This technology not only has the advantages of less process, no cutting or less cutting, and high economic benefits, but also overcomes the uneven material, low mechanical properties, difficulty of thin-wall forming, structure and structure of traditional powder metallurgy products.

What are the characteristics of injection molding? MIM powder injection manufacturers explain to you

MIM powder injection manufacturers believe that metal injection molding, as a near-net-shape technology for manufacturing high-quality precision parts, has incomparable advantages over traditional processing methods. MIM can manufacture many parts with complex shape features, such as various external grooves, external threads, tapered external surfaces, cross holes, blind holes, quad and key pins, stiffeners, surface knurls, etc. This is not available with conventional powder metallurgy methods. Material consumption is reduced as parts manufactured by metal injection moulding require little re-machining. Therefore, when the number of parts with complex shapes that need to be produced is higher than a certain value, MIM will
