Hot Rolled Forged Rail Wheels 851mm Diameter For Locomotive Wagons

AAR-B forged and hot rolled tyres 851mm diameter for Kenya locomotive and wagons

To meet increasingly developing requirement of ring market, we continuously developed new product in the recent years. The main products include gear ring, bearing ring and flange series.
Rings with different types section figure can be produced in the company. Dimension scope of ring:: Out diameter300~4000mm; inner diameter≥200mm; Height: 50~400mm.The Kingrail tire adopts a high-strength and light-weight rail vehicle tire and its production process, which relates to the technical field of alloy preparation. The clamping seat includes a clamping table that is coaxial with the outer tire and a retaining ring that is integrally connected and fixed on the outer side of the bottom surface of the clamping table. The end surface of the clamping table is evenly distributed with a number of threaded through holes; the bottom end surface of the outer tire is integrally connected and fixed with a tread ring. The surface of the tread ring is an annular surface that completely coincides with the bottom surface of the outer tire. The inner side of the annular surface is bent vertically outward to form an arc-shaped tread extending downward and outward, and the outer side of the annular surface is vertically outward. Bending to form an outer arc surface whose bottom end coincides with the outer edge of the arc-shaped tread; the tread of the tire of the present invention is made into a 5-degree inclined surface, which can reduce the quality of the wheelset, facilitate the passage of the curve, and also make the tread wear and tear comparison. Evenly, by lowering the center of gravity of the vehicle, the mass of the wheelset is reduced, and the flexibility of the track wheel into the track is improved.

Parts of ultrasonic testing instruments for testing tires. The basic shape of the shell of the probe is a rectangular shell; the first wafer group is bonded and fixed on the upper end face of the first delay block to form the first transmitting and receiving assembly, and the second wafer group is bonded and fixed on the second delay block The second transmitting and receiving assembly is formed on the upper end face of the first chip group; the first transmitting and receiving assembly and the second transmitting and receiving assembly are fixed and bonded to the shell through the block of sound-absorbing material; the transmitting and receiving surface of the piezoelectric chip of the first wafer group faces downward Set on the left, the transmitting and receiving surface of the piezoelectric chip of the second wafer group is set downward and rightward; the degree α of the acute dihedral angle formed by the plane where the end face of the piezoelectric chip is placed and the plane where the lower end face of the probe is located is the degree α of 20 degrees to 78 degrees; the shape of the lower end face of the entire probe is a circular arc surface corresponding to the radial outer peripheral arc surface of the tire to be tested. When the probe is used, the detection is accurate, time-saving and labor-saving.

The adopted method for processing and clamping a tire and a clamping and positioning method is characterized in that: it comprises a bottom plate of the tool and a reference pad set on it to support the tire; The precise positioning block for positioning the tire, the clamping tool also includes a clamping mechanism for pressing the tire from above to realize the axial positioning of the tire. The invention has the advantages of simple and reasonable structure, high degree of automation, accurate and stable positioning, and can greatly improve work efficiency, reduce labor intensity, and has good application prospects.
