B6E forging tyres 550mm diameter for Netherlands light street rail car and tram
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.
Rings used for rotary support can be produced based on international advanced standard such as S48C ring of JIS standard..
In order to further improve the product quality and broaden the specification,Kingrail build another new wheel forging production line and one wheel machine line consist of 8 digital-control machine table with large diameter and high precision.
In order to provide an annular tire for the pressure rollers of a rolling machine for crushing granular materials, the outer surface of which always has a high hardness and thus high wear resistance, but its radially inner region is In order to avoid tire cracks with low hardness, it is proposed according to the invention that the material of the tire (10, 11) consists of ductile iron with at least alloy elements Ni and Mo and a bainitic structure with residual austenite, ring wheel The surface layer (11) of the hoop (10) contains martensite in order to form a self-hardening surface, which is continuously reformed during the operation of the rollers by external pressure loading of the tire surface
A roller, a method for removing a tire and a method for shrink-fitting a tire onto a shaft of a roller: the roller comprises a shaft (1) and a wear-resistant tire (3), wherein, The tire (3) is shrink fit onto the shaft (1) in a non-positive manner. 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.
