Abstract

A marine outboard motor with double clutches belongs to a marine power device. The technical characteristic is that a centrifugal clutch is arranged at the output shaft end of the power machine, and the centrifugal clutch adopts a flyweight centrifugal main and auxiliary friction disc structure: a reverse and forward gear clutch is arranged between the propeller and the vertical shaft, and the clutch adopts a bevel gear jaw type structure. The double clutch layout scheme is adopted, so that the on-hook has the advantages of safe and reliable clutch during power driving, convenience and freedom in reversing and reversing, simple structure and difficulty in damage.

Description

Marine propeller with double clutches

The utility model relates to a kind of marine power plant, specifically a kind of Marine outboard motor with double-clutch.

At present, be applicable to that the industrial or agricultural transportation that has a large capacity and a wide range, the horizontal vertical shaft diesel engine direct connection on-hook of small fishing vessel still belong to blank.Now, generally connect indirectly with on-hook through belt train, commutation change speed gear box with the horizontal axis diesel engine.This connecting mode owing to there is intermediate link, makes on-hook complex structure, heaviness, cost height, lower, the maintenance dismounting difficulty of driving efficiency.

In addition, tooth embedding coupler rigid attachment is all adopted in spark ignition engine or diesel engine and on-hook.When screw propeller is run into obstacle, cause screw propeller to damage and overload easily, even flame-out phenomenon.

Also have the ahead running of on-hook generally to adopt simple straight-tooth dental clutch and rigid lever formula shift fork, complex structure, the clutch difficulty, collide loud, damage easily.

The purpose of this utility model is to provide a kind of Marine outboard motor with double-clutch, and it is safe and reliable to make it the power clutch, and ahead running is convenient freely.

Technical solution of the present utility model is to establish a centrifugal clutching at the output axle head of engine to close device, and this power-transfer clutch adopts the centrifugal major-minor friction disc of flyball structure; Establish down between screw propeller and vertical shaft along the shelves power-transfer clutch, this power-transfer clutch adopts the castellated structure of bevel gear.

Owing to adopted above-mentioned technical solution, make the utility model realize that the clutch of power driving is safe and reliable, ahead running is convenient freely, and simple in structure, not fragile.

Embodiment:

Accompanying drawing has been described an embodiment of the present utility model.Below in conjunction with accompanying drawing the utility model is described in detail.Fig. 1 is the total arrangement with Marine outboard motor of double-clutch, and it comprises power support 1, bar handle assembly 2, bracket assembly 3, vertical shaft assembly 4, screw propeller casing assembly 5 etc.Be provided with as shown in Figure 2 centrifugal clutch at the output axle head of engine.This power-transfer clutch is made up of support 7, flyball 9, main friction disc 10, secondary friction disc 11 etc.Support 7 is fastening with crankshaft of diesel engine 6, and flyball 9 upper inner are processed with colludes groove, and the centre is drilled with pin-and-hole, connect with support 7 with straight pin 8, and rotatable; Main friction disc 10 usefulness inner spline housings can slide up and down on bent axle 6, and secondary friction disc 11 usefulness flat keys are fastened on the main shaft 12 of on-hook.Behind diesel engine starting, bent axle 6 rotations, the flyball bottom is under action of centrifugal force, outwards open, top is colluded groove face and main friction disc is pushed into downwards to contact with the conical surface of secondary friction disc 11 is produced friction force, thereby drive 12 rotations of on-hook vertical shaft, and castellated through bevel gear along the commutation of shelves power-transfer clutch, drive screw propeller and rotate.

Fall along the shelves power-transfer clutch as shown in Figure 3, it is by

bevel gear

14,13,16, sliding sleeve 22, slide-bar 20, spring 25, shift fork 19 compositions such as grade.Sliding sleeve 22 usefulness keys (this example is two flat keys) are contained on the prop shaft 21, can horizontally slip, its two ends and the embedding of screw serrated form tooth, slide-bar 20 can slide in prop shaft 21 holes, retracing spring 25 is equipped with on its top, and be in compressive state, and sliding sleeve 22 combines as a whole with slide-bar 20 usefulness straight pins 23, and straight pin 23 can slide in the rectangular groove of prop shaft 21.Bevel gear 14 usefulness inner spline housings are 12 among Fig. 2 at vertical shaft 15() on, positive reverse gear bevel gear 16 and 13 endoporus are equipped with

copper sheathing

17 and 24 respectively, can rotate on prop shaft, and its inner is the embedding of screw serrated form tooth.Mild steel rope 18 connects with on-hook gear shifting handle and shift fork 19, and shift fork 19 is contained in the right-hand member of slide-bar 20.When gear shifting handle places Neutral Position, sliding sleeve 22 mediates, and the helix tooth embedding at its two ends breaks away from the positive reverse gearwheel 16 on both sides and 13 helix tooth embedding.Start diesel engine.Centrifugal clutch drives vertical shaft 15 rotations, and bevel gear 14 drives positive reverse gearwheel 16 and 13 idle running; Gear shifting handle is placed the ahead running position, and steel wire 18 is loose, and spring 25 resets, and pushes slide-bar 20 and sliding sleeve 22 to right-hand member, and the tooth embedding wedging of the positive shelves gear 16 of the tooth embedding of sliding sleeve 22 right-hand members and right-hand member drives prop shaft 21 rotations, and boats and ships advance; Gear shifting handle is fixed on car backing position, and handle upwards spurs steel wire 18, and the bulb of shift fork 19 pushes away slide-bar 20 left, and the tooth embedding wedging of the tooth embedding of sliding sleeve 22 left ends and the bevel gear 13 on the left side drives the counter-rotating of prop shaft 21 and screw propeller, and boats and ships fall back.
