  • Patent number: 6158897
    Abstract: A gear including a frame, a first shaft, a first gearwheel arranged on the first shaft and in engagement with a second gearwheel mounted on a second shaft, the second shaft including bearings at both sides of the second gearwheel between the frame and the second shaft. The second shaft revolves about the bearings placed on each side of the second gearwheel. At least one spring is fitted to act with a force upon an outer race of rolling members of one of the bearings. A glide fitting is provided between a circumferential face of the outer race and the gear frame or a connected part. The force effect applied by the spring(s) is transferred through the rolling members of the bearing to the inner race of the bearing and further to the other bearing placed at the opposite side of the gearwheel whereby the play in both bearings between the rolling members and the bearing races is eliminated.
