Abstract
The utility model discloses a gear box used for a reinforced ship which includes a box body, a transmission shaft and an idle gear; the two ends of the transmission shaft are arranged on the box body; the idle gear is engaged with a transmission gear fixed on the transmission shaft; an idle gear shaft is arranged in the box body; the two ends of the idle gear shaft are arranged on the box body; the idle gear is sleeved on the idle gear shaft and is engaged with the transmission gear. In the gear box used for the reinforced ship, a cantilever structure is changed into a support structure the two ends of which are fixed under the premise of keeping the original mounting size to be unchanged, which improves the intensity of the idle gear, and meets various using requirements of the gear box used for the ship.
Description
Technical field
The utility model relates to a kind of marine gearbox, specifically a kind ofly can satisfy marine gearbox at the reinforced marine gearbox that falls, ahead running has the various usage requirements of identical transmission capacity when working.
Background technique
Existing marine gearbox idle gear is a cantilever structure, sees Fig. 1, comprises casing 11, driving gear 12, input shaft 13, idler shaft 14, idle gear 15 and driven gear 16, and wherein an end of idler shaft 14 is cantilever structure by being bolted on the casing 11.When the marine gearbox of this structure applies to unit peculiar to vessel when supporting, because reversing uses the idle gear state less during the boats and ships operation, so can satisfy normally use.Marine gearbox extensively applied in the market to dig sand, weighed anchor, machinery such as stirring supporting, at this moment idle gear can be often in running order, thereby since idle gear for being cantilever structure, support strength is poor, so can not satisfy marine gearbox in the requirement of falling, ahead running has identical transmission capacity when working, fault is many.
Summary of the invention
In order to overcome the existing problem of idle gear of existing cantilever structure, the purpose of this utility model provides a kind of reinforced marine gearbox, this gear-box is keeping making cantilever structure into the two ends fixed support structure under the constant prerequisite of original installation dimension, improved idle gear intensity, satisfied marine gearbox in the requirement of falling, ahead running has identical transmission capacity when working.
The purpose of this utility model is achieved through the following technical solutions:
A kind of reinforced marine gearbox, comprise casing, transmission shaft and idle gear, the two ends of transmission shaft are arranged on the casing, idle gear and the driving gear engagement that is fixed on the transmission shaft, it is characterized in that: in casing, be provided with the idle gear axle, the two ends of idle gear axle are arranged on the casing, and described idle gear is sleeved on the idle gear axle and with driving gear and meshes.
In the utility model, the two ends of described idle gear axle are arranged on the casing by bearing.
Compared with prior art, the utility model makes the idle gear of the cantilever structure in original marine gearbox by the fixing two end supports structure of idle gear axle into, and keep original installation dimension constant, improved idle gear intensity, satisfied marine gearbox in the requirement of falling, ahead running has identical transmission capacity when working.
Description of drawings
Fig. 1 is that existing idle gear is the marine gearbox structural representation of cantilever structure;
Fig. 2 is a structural representation of the present utility model.
Embodiment
A kind of reinforced marine gearbox described in the utility model is seen Fig. 2, and this reinforced marine gearbox comprises casing 1, transmission shaft 2 and idle gear 3, and the two ends of transmission shaft 2 are arranged on the casing 1, are provided with driving gear 4 on transmission shaft 2.Idle gear 3 is arranged in the casing 1.Be provided with idle gear axle 5 in casing 1, the two ends of idle gear axle 5 are arranged on the casing 1 by bearing 6, and idle gear 3 is sleeved on the idle gear axle 5 and with the driving gear 4 that is fixed on the transmission shaft 2 and meshes.
The utility model makes the idle gear of the cantilever structure in original marine gearbox by the fixing two end supports structure of idle gear axle into, and keep original installation dimension constant, improved idle gear intensity, satisfied marine gearbox in the requirement of falling, ahead running has identical transmission capacity when working, even frequent use of idle gear can not broken down yet.
Claims (2)
