<p>The invention concerns 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). The shaft (16) comprises bearings (18 and 19) at both sides of the gearwheel (17) between the frame (11) and the shaft (16). The gear comprises a spring/springs (23a1, 23a2...), which is/are fitted to act with a force (F) upon the outer race (18') of the rolling members (20a1, 20a2...) of the bearing (18). Between the circumferential face (C1) of the outer race (18') and the gear (10) frame (11) or a connected part there is a glide fitting. In this connection the force effect is transferred further through the rolling members (20a1, 20a2...) of the bearing (18) to the inner race (18'') of the bearing (18) and further to the bearing means (19) placed at the opposite side of the gearwheel (17). In this way the play in the bearings (18 and 19) placed at both sides of the gearwheel (17), between the rolling members (20a1, 20a2...) and the bearing (18, 19) races (18', 18''; 19', 19''), is eliminated.</p> |
