Abstract
The utility model discloses an outboard engine driving shaft counter-rotating thrust device, which comprises a driving shaft. The driving shaft is vertically arranged in an underwater device shell through an upper gear bearing and a lower gear bearing. The lower end of the driving shaft is provided with a driving gear. A plane bearing is arranged between the driving gear and the underwater device shell. Both the upper gear bearing and the plane bearing belong to a thrust bearing. The utility model controls gear backlash through the thrust bearings, solves the stress problem in the counter-rotating process of the driving shaft, has the advantages of simple structure and high reliability and can effectively improve power transmission efficiency and reduce noise.
Description
Technical field
The utility model relates to a kind of outboard engine axle drive shaft rotating thrust brake.
Background technology
Outboard engine is when work, and the power of driving engine output is delivered to downwards on the shift gear that is installed in gear case by the driving gear that is installed on the axle drive shaft, shift gear and prop shaft engagement, and prop shaft drives the screw propeller rotation, produces thrust.In this power transmittance process, shift gear can be to antagonistic force of driving gear, and this antagonistic force can influence power transfer efficiency.Because the driving gear flute profile is a screw bevel gear, the antagonistic force direction that produces when the antagonistic force that is producing when axle drive shaft is just changeing reverses with axle drive shaft is opposite, traditional drive mechanism can't solve the positive and negative running of axle drive shaft, adopts a pair of shift gear of layout and power-transfer clutch to realize rotating and reverse of prop shaft usually.
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, on the device case, another is fitted on the underwater units case lid one of them bearing press mounting under water, and shift gear is installed on these two bearings, realizes reducing the purpose of shift 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 shift gear with the power of driving engine, driving gear and shift 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 axle drive shaft just changes, shift gear can produce an application force that pulls down to driving gear, when axle drive shaft reverses, shift gear can produce an application force that upwards pushes away to driving gear, these two application forces all can have influence on the relative position of driving gear and shift gear, thereby have influence on the size of gear backlash.
Summary of the invention
The utility model purpose is: the thrust brake that the positive and negative running of a kind of outboard engine axle drive shaft is provided, last gear shaft in this device holds with surface bearing and is thrust bearing, by the size of thrust bearing pinion sideshake, thus the stressed problem of the opposite axial reaction force of helical wheel initiatively when solving the positive and negative running of axle drive shaft.
The technical solution of the utility model is: a kind of outboard engine axle drive shaft rotating thrust brake, comprise by last gear shaft and holding and following gear shaft holds the axle drive shaft that is vertically mounted in the underwater units housing, the lower end of axle drive shaft is equipped with driving gear, between driving gear and the underwater units housing surface bearing is housed, described upward gear shaft holds with surface bearing and is thrust bearing.
The further technical scheme of the utility model is: a kind of outboard engine axle drive shaft rotating thrust brake, comprise by last gear shaft and holding and following gear shaft holds the axle drive shaft that is vertically mounted in the underwater units housing, the lower end of axle drive shaft is equipped with driving gear, between driving gear and the underwater units housing surface bearing is housed, described upward gear shaft holds with surface bearing and is thrust bearing; The underwater units housing that described upward gear shaft holds the below is provided with step, is provided with shimming plate between step and last gear shaft hold, and is provided with shimming plate between described surface bearing and the driving gear.
The utility model advantage is:
The utility model under water in the bearing of the drive axis position on the device case the last gear shaft away from driving gear hold the employing thrust bearing, by the size that thrust bearing cooperates shimming plate to come the pinion sideshake, realize reducing the purpose of friction drag.
2. the surface bearing between driving gear and the underwater units housing adopts thrust bearing in the utility model, by the size that thrust bearing cooperates shimming plate to come the pinion sideshake, realizes reducing the purpose of friction drag.
3. the utility model is simple in structure, and the reliability height has solved the bidirectional stress problem, can effectively improve power transfer efficiency, reduces noise.

Fig. 1 is a structural representation of the present utility model.
Wherein: gear shaft holds on 1; 2 times gear shaft holds; 3 underwater units housings; 4 axle drive shafts; 5 driving gears; 6 steps; 7 shimming plates; 8 surface bearings; 9 shimming plates; 10 shift gears; 11 pads.
The specific embodiment
Embodiment: as shown in Figure 1, a kind of outboard engine axle drive shaft rotating thrust brake, comprise by last gear shaft hold 1 and following gear shaft hold 2 and be vertically mounted on the interior axle drive shafts 4 of underwater units housing 3, the lower end of axle drive shaft 4 is equipped with driving gear 5, between driving gear 5 and the underwater units housing 3 surface bearing 8 is housed, wherein said go up gear shaft hold 1 and surface bearing 8 be thrust bearing, the underwater units housing 3 that last gear shaft holds 1 below is provided with step 6, step 6 and last gear shaft are provided with shimming plate 9 between holding 1, are provided with shimming plate 7 between surface bearing 8 driving gears 5.
Above-mentioned driving gear 5 is a screw bevel gear, axle drive shaft 4 is that the driving gear 5 by being installed in axle drive shaft 4 ends is delivered to shift gear 10 with the power of driving engine, in the power transmittance process, have influence on the size of gear backlash for fear of the application force of 10 pairs of driving gears of shift gear, 5 generations, go up in the utility model gear shaft hold 1 and surface bearing 8 all adopted thrust bearing, by the size that thrust bearing cooperates shimming plate 7,9 to come the pinion sideshake, realize reducing the purpose of friction drag.
Above-mentioned axle drive shaft can be provided with the pad 11 of different-thickness above surface bearing 8, to satisfy different assembling demands.
Stressed problem when the utility model has solved the driving gear rotating, simple in structure, the reliability height can effectively improve power transfer efficiency, reduces noise.
