Abstract
The utility model relates to a gear especially relates to a marine gearbox intermediate gear. It mainly is that to solve the intermediate gear structure that gear box that prior art exists adopted comparatively complicated, installs comparatively difficultly, and transmission efficiency is lower, and manufacturing cost is higher to intensity is relatively poor, and corrosion resistance is lower, technical problem that life is short etc.. The utility model discloses a gear body (1), the excircle of gear body (1) be equipped with denticle (2), the root of denticle is equipped with strengthens alloy piece (3), strengthens the alloy piece and is embedded into inside the gear body.
Description
Technical field
The utility model relates to a kind of gear, especially relates to a kind of marine gearbox intermediate gear.
Background technique
Marine gearbox is a most important transmission device in boat transmission, and the power transimission that it is responsible for motor to send to propeller cavitation, thus realizes the motion of boats and ships.Chinese patent discloses a kind of marine gearbox (Authorization Notice No.: CN2700643Y), it includes casing, be placed in the ahead running parts in casing, reversing parts, intermediate member and output block, in ahead running parts, the input end of input shaft is equipped with input coupling, on axle, kink has ahead running driving gear, be fastened with ahead running driving gear, ahead running clutch is housed between two gears, ahead running driving gear engages with the reversing driving gear in reversing parts, ahead running driving gear and the driving gear of moveing backward in parts engage with the driven gear in intermediate member simultaneously respectively, driven gear engages with the output gear be fastened in output block on output shaft, the output terminal of output shaft and the input end of input shaft are positioned at casing the same side, ahead running driving gear and reversing driving gear are respectively enclosed within by sliding bearing on the reverse shaft of input shaft and reversing parts respectively, are respectively provided with the friction clutcch controlled by hydraulic control valve between the driving gear in ahead running parts and reversing parts and driving gear, hydraulic control valve is placed in the shaft end of input shaft, and with Joystick, input shaft is positioned at the top of casing, and output shaft is positioned at the bottom of casing.But the intermediate gear structure that this gear-box adopts is comparatively complicated, install comparatively not easily, transmission efficiency is lower, and cost of production is higher, and intensity is poor, and corrosion resistance is lower, and working life is shorter.
Model utility content
The utility model is to provide a kind of marine gearbox intermediate gear, its intermediate gear structure mainly solving the gear-box employing existing for prior art is comparatively complicated, install comparatively not easily, transmission efficiency is lower, cost of production is higher, and intensity is poor, corrosion resistance is lower, working life shorter grade technical problem.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Marine gearbox intermediate gear of the present utility model, comprises gear, and the cylindrical of described gear is provided with denticle, and the root of denticle is provided with reinforcement alloy block, strengthens alloy block and is embedded into gear inside.Strengthen the intensity that alloy block can strengthen denticle root, can be embedded into the inside of gear owing to strengthening alloy block, therefore the connection of denticle and gear is tightr.
As preferably, in the axis hole of described gear, be provided with the step that more than 3 internal diameters are different.By different steps, intermediate gear can be made can to select the transmission shaft of dress different size, and Applicable scope is wider.
As preferably, the inside of described gear has oiling groove, and oiling groove is communicated with end face and the axis hole of gear, and oiling groove is oblique setting.Can carry out lubricated to gear at any time by oiling groove, the oblique setting of oiling groove, can not affect the intensity of whole gear.
Therefore, the utility model arranges stiffening plate at the root of denticle, makes denticle and gear tightr in combination, thus make intensity comparatively strong, and step is set in gear, make assembling Applicable scope wider, oiling groove is used to make working life longer, simple and reasonable for structure.
Accompanying drawing explanation
Accompanying drawing 1 is a kind of structural representation of the present utility model.
Component, position and numbering in figure: gear 1, denticle 2, reinforcement alloy block 3, step 4, oiling groove 5.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: the marine gearbox intermediate gear of this example, as Fig. 1, comprises gear 1, and the cylindrical of gear is provided with denticle 2, and the root of denticle is provided with strengthens alloy block 3, strengthens alloy block and is embedded into gear inside.The step 4 that 3 internal diameters are different is provided with in the axis hole of gear.The inside of gear has oiling groove 5, and oiling groove is communicated with end face and the axis hole of gear, and oiling groove is oblique setting.
During use, the utility model is encased in marine gearbox.
The foregoing is only specific embodiment of the utility model, but structure characteristic of the present utility model is not limited thereto, any those skilled in the art is in field of the present utility model, and the change done or modification are all encompassed among the scope of the claims of the present utility model.
