YN920 Railway Tyres 915mm Outside Diameter For Vietnam Locomotive

YN920 rail tyres for for Vietnam locomotive 915mm outside diameter

Kingrail applied A high-strength light-weight rail vehicle tire and a production process thereof are used, and relate to the technical field of alloy preparation.

A roll (2) of a high-pressure roller press, the roll comprising a shaft (1) and a wear-resistant tire (3), wherein the tire (3) is heat-fitted to the shaft ( 1) on. Furthermore, the invention relates to a method for separating a tire (3) and a shaft (1) in such a roller (2) and a method for non-positively locking the tire (3) and the shaft (1) A method of connecting into such a roller (2). According to the invention it is provided that the shaft ( 1 ) has a plurality of cooling holes ( 5 ) penetrating in the axial direction for the passage of a gaseous or liquid coolant, wherein the cooling holes ( 5 ) are provided in the outer area of the shaft (1). Furthermore, in order to separate the wheel ( 3 ) from the shaft ( 1 ) it is provided that the wheel ( 3 ) is heated by means of an external heat supply, whereby the shaft ( 1 ) is heated by means of the coolant flowing through the cooling holes ( 5 ). cooling; and removing the tire (3) from the shaft (1) in the longitudinal direction.

The tires of KINGRAIL are easy to transport, because they are a kind of pressure plate packaging of wheel tires, which includes a tire outer cylinder and at least three sets of fasteners. Outside the wheel rim, the outer cylinder of the rim includes several rim placement layers; each group of fasteners has the same structure and specification, and the fasteners include two spacers, two long double-ended screws and four nuts, The two spacers are respectively arranged on the upper end and the lower end of the outer cylinder of the tire. There are two through holes on the spacer block. The screw rod is set close to the inner circle of the outer cylinder of the tire, and the other double-headed screw is set close to the outer circle of the outer cylinder of the tire. The pressing plate type packaging of the wheel rim proposed by the utility model has the advantages of simple structure, convenient processing and manufacturing, and convenience for the transportation and storage of the wheel rim.

The tire is used to assemble rubber elastic wheels. The tire is a rolled seamless steel ring, which is pressed on the wheel center by thermal effect. The wheel center is a cast steel wheel body, and there is a layer of rubber body between the tire and the wheel center. If bubbles or slag remain during the rolling of the tire, it may crack under the dynamic action of high pressure load, or it may be caused by "fatigue fracture" due to the aging of the tire material. KINGRAIL's tires ensure quality and safety.
