  • Shaft coupling
    Patent number: 11624408
    Abstract: A shaft coupling includes a first coupling member, a second coupling member, and a cushioning member. The first coupling member includes first protrusions. The second coupling member includes second protrusions. The cushioning member includes a plurality of radiating portions. When the first coupling member and the second coupling member are arranged coaxially and the first coupling member and the second coupling member are in an unloaded state, predetermined paired facing surfaces have a minimum clearance angle present on a radially outer side with respect to a center of the radiating portion in a radiating direction. The predetermined paired facing surfaces are at least one of first paired facing surfaces and second paired facing surfaces.

  • Speed reducer and electric power steering system
    Patent number: 9061698
    Abstract: A speed reducer for an electric power steering system includes a worm, a worm wheel, and a housing. Only a meshing section where the worm and the worm wheel mesh with each other and a space between the worm wheel and the housing are filled with grease. The grease in the space is in contact with both tooth surfaces of the worm wheel and an inner peripheral face of the housing, the inner peripheral face facing the worm wheel.
