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.
A gear, which comprises a shaft (12) and on it a gearwheel (13), which is in engagement with a gearwheel (17) mounted on a shaft (16), and that the shaft (16) comprises first and second bearings (18 and 19) arranged along opposite sides of the gearwheel (17) between the frame (11) and the shaft (16), on which bearings the shaft (16) is fitted to revolve, characterized in that the gear comprises at least one spring fitted to act with a force (F) upon an outer race (18') of said first bearing (18);
In a gear including a frame, a first shaft, a first gearwheel arranged on the first shaft, a second shaft, a second gearwheel arranged on said second shaft and in engagement with the first gearwheel and first and second bearings arranged on a respective first and second side of the second gearwheel between the frame and the second shaft for revolvingly supporting the second shaft relative to the frame, the improvement comprising:
