  • Hydrodynamic sliding surface bearing
    Patent number: 4538929
    Abstract: The friction conditions in a hydrodynamic surface bearing having a bearing metal layer in which no softer bearing metal is embedded are substantially improved in that the bearing surface is formed with grooves, which are distributed over the width of the bearing and include with the direction of movement in the bearing an angle not in excess of 20.degree.. These grooves cooperate with the moving element to be received in the bearing so as to define passages which ensure that a minimum hydrodynamic pressure will be built up in the lubricant.
