Abstract
The utility model discloses a thrust device below an outboard engine driving shaft, which comprises a driving shaft installed in an underwater unit shell through a shift-up bearing and a shift-down bearing, a driving gear is installed at the lower end of the driving shaft, a step is arranged on the underwater unit shell above the driving gear, a planar thrust bearing is installed on a driving shaft between the step and the driving gear, and a filling piece is arranged between the planar thrust bearing and the driving gear; since the planar thrust bearing is arranged between the driving gear and the underwater unit shell and is matched with the filling piece to control the size of the gear backlash, the purpose of reducing the frictional resistance is achieved, and the utility model not only has simple structure and high reliability, but also can effectively improve the power transmission efficiency and reduce the noise.
Description
Technical field
The utility model relates to thrust brake under a kind of outboard engine axle drive shaft.
Background technology
Outboard engine is when work, and the power of driving engine output is by being delivered under the driving axial on the shifting gear that is installed in gear case, and shifting gear and prop shaft mesh, and prop shaft drives the screw propeller rotation, produces thrust.In this power transmittance process, can produce friction drag, influence power transfer efficiency, also can produce noise.
For the friction drag in the depowering transmittance process, improve power transfer efficiency, reduce noise, be furnished with several bearings under water in the device case and be used to reduce friction drag; Be furnished with two bearings in the prop shaft axial location, one of them bearing press mounting is under water on the device case, another is fitted on the underwater units case lid, and two shifting gears are installed in respectively on these two bearings, realizes reducing the purpose of shifting gear spin friction power; At the driving axis shaft position, tandem is arranged two bearings, realizes reducing the purpose of axle drive shaft spin friction power.In addition, axle drive shaft is that the driving gear by being installed in the axle drive shaft top is delivered to shifting gear with the power of driving engine, driving gear and shifting gear engagement, the driving gear flute profile is a screw bevel gear, friction drag during its work and noise are subjected to the influence of gear backlash.In the power transmittance process, when the hand of rotation of the helical angle of design-calculated driving gear (A to) and driving gear is identical, shifting gear can produce an application force that upwards pushes away to driving gear, this application force can have influence on the relative position of driving gear and shifting gear, thereby has influence on the size of gear backlash.
Summary of the invention
The utility model purpose is: thrust brake under a kind of outboard engine axle drive shaft is provided, this device is arranged a plane thrust bearing between driving gear and underwater units housing, by the size that the plane thrust bearing cooperates shimming plate to come the pinion sideshake, realize reducing the purpose of friction drag.
The technical solution of the utility model is: thrust brake under a kind of outboard engine axle drive shaft, comprise by perform bearing and lower gear bearing and be vertically mounted on axle drive shaft in the underwater units housing, the lower end of axle drive shaft is equipped with driving gear, the underwater units housing of described driving gear top is provided with step, and the axle drive shaft between step and the driving gear is equipped with the plane thrust bearing.
The further technical scheme of the utility model is: thrust brake under a kind of outboard engine axle drive shaft, comprise by perform bearing and lower gear bearing and be vertically mounted on axle drive shaft in the underwater units housing, the lower end of axle drive shaft is equipped with driving gear, the underwater units housing of described driving gear top is provided with step, and the axle drive shaft between step and the driving gear is equipped with the plane thrust bearing; Be provided with shimming plate between described plane thrust bearing and the driving gear.
The utility model advantage is:
1. the utility model is arranged a plane thrust bearing between driving gear and underwater units housing, by the size that the plane thrust bearing cooperates shimming plate to come the pinion sideshake, realizes reducing the purpose of friction drag.
2. the utility model is simple in structure, and the reliability height can effectively improve power transfer efficiency, reduces noise.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is a structural representation of the present utility model.
Wherein: 1 bearing that performs; 2 lower gear bearings; 3 underwater units housings; 4 axle drive shafts; 5 driving gears; 6 steps; 7 plane thrust bearings; 8 shimming plates.
The specific embodiment
Embodiment: as shown in Figure 1, thrust brake under a kind of outboard engine axle drive shaft, comprise by perform bearing 1 and lower gear bearing 2 and be vertically mounted on axle drive shaft 4 in the underwater units housing 3, the lower end of axle drive shaft 4 is equipped with driving gear 5, the underwater units housing 3 of described driving gear 5 tops is provided with step 6, axle drive shaft 4 between step 6 and the driving gear 5 is equipped with plane thrust bearing 7, is provided with shimming plate 8 between plane thrust bearing 7 and the driving gear 5.
Axle drive shaft 4 is that the driving gear 5 by being installed in axle drive shaft 4 tops is delivered to shifting gear with the power of driving engine, driving gear 5 and shifting gear engagement, driving gear 5 flute profiles are screw bevel gear, and friction drag during its work and noise are subjected to the influence of gear backlash.In the power transmittance process, shifting gear can produce an application force that upwards pushes away to driving gear 5, and this application force can have influence on the relative position of driving gear 5 and shifting gear, thereby has influence on the size of gear backlash.Between driving gear 5 and underwater units housing 3, arrange a plane thrust bearing 7,, realize reducing the purpose of friction drag by the size that plane thrust bearing 7 cooperates shimming plate 8 to come the pinion sideshake.
The utility model is simple in structure, and the reliability height can effectively improve power transfer efficiency, reduces noise.
