DEVICE FOR JOINING TRACK RAILS Russian patent published in 1999 - IPC

FIELD: construction of railway tracks. SUBSTANCE: for joining track rails, rails are made with sharpened ends. Angle of sharpening is 15-30 deg. Value of clearance in joint is determined according to formula b = C•sinα, where C - standard clearance, α - - angle of sharpening of rail ends. Sharpened ends of rails as to their rolling surface are bevelled at angle of β - 1-3 deg. and over length of 10-25 mm counting from point of sharpening. Application of aforesaid arrangement of components raises efficiency of rail joint operation. EFFECT: higher efficiency. 2 cl, 3 dwg
