Abstract
The utility model relates to a gear shifting mechanism for ship outboard paddles, which is matched with outboard paddles and is used on ships with small tonnages. The utility model is formed by that a gear shifting device is connected with a driving mechanism, wherein, the gear shifting device is formed by that a shifting fork with a positioning device composed of a steel ball, a spring, and a screw plug is connected with a shifting fork shaft and then is connected with a sliding sleeve on a clutch shaft. When the utility model is used, a ship can be made to move forwards or backwards only by wrenching a handle form an O position to an A or a B position, and the structure is simple and compact. The operation is similar to handle gear shifting of an automobile, so that the gear shifting is light and comfortable. The bidirectional locking position of the shifting fork with the shifting fork shaft and the clutch shaft and with the sliding sleeve and the steel ball is adopted, locking force is increased by times, and the reliability and the safety of use are raised.
Description
The utility model relates to a kind of gear shift mechanism, and is particularly supporting with ship extension oar, is used for the ship of little tonnage, and power resources are in diesel engine.By this gear shift mechanism, realize hanging oar screw propeller forward or reverse, thus the boat oar gear shift mechanism of managing a boat and advancing or falling back or stop.
Existing extension oar gear shift mechanism complex structure, not easy-maintaining, adjustment.
The purpose of this utility model is, provides a kind of boat oar gear shift mechanism only to be used for paper boat, and it is simple in structure, compact, good reliability, easy to use, operates light and handy, comfortable.
The utility model be achieved in that the boat oar gear shift mechanism by be fixed on the casing Shift lever by shifting apparatus be connected with transmission device the institute form, and described shifting apparatus is to have the shift fork that constitutes registration device by steel ball, spring, plug screw to be connected with declutch shift shaft, be connected with sliding sleeve on the clutch spindle again form.
Fig. 1. structural representation of the present utility model (having omitted second half finishing bevel gear cuter on the clutch spindle).
Fig. 2. the left view of Fig. 1 (C-C view).
Below in conjunction with accompanying drawing embodiment of the present utility model is further described:
Be to communicate and vertical cylindrical in the middle of the shift fork (7) with the upper end, the lower end is pincerlike, there is " U " shape projection at the intermediate cylindrical place, and positioning ball (5), spring (4) are installed in the cylindrical hole of upper end, and is fixed on the registration device of the end formation of shift fork (7) with the screw thread on the plug screw (3).
One end of declutch shift shaft (8) is a screw thread, screws on tower of casing (6), and an end is a screw head, and there are three cambered surface grooves that cooperate with steel ball (5) that the interval is identical the centre.
Shift lever is handle (1), and handle (1) is installed on the box cover (2) by bearing pin, and handle (1) one end bulb embeds in " U " shape projection of shift fork (7).
Sliding sleeve (10) female splines axis direction has three uniform semicircle knock holees, is used for steel ball (5) location, and the both ends of the surface outward flange respectively has three uniform tooth embeddings, and there is a cambered surface groove neighboring.
Shift fork (7) is enclosed within on the declutch shift shaft (8), and makes the cambered surface groove fit on steel ball (5) and the declutch shift shaft (8) on it, and two pincers pin of shift fork (7) lower end are embraced in sliding sleeve (10) groove of band female splines.
Finishing bevel gear cuter in the transmission device (11) endoporus and clutch spindle (12) external diameter are moving joins, and end face has three equal dog embeddings and sliding sleeve (10) tooth embedding engagement.
There is a blind hole at the male splines place of clutch spindle (12), in spring (4) and steel ball (5) are housed, can cooperate with three semicircle knock holees in the sliding sleeve (10), make location usefulness, the other end is equipped with Pulley, can transmit diesel powered (figure is picture).
During use, handle (1) is pulled the B position from 0 position (stop bit), at this moment handle (1) end just promotes shift fork (7) along declutch shift shaft (8) distance that moves right, and shift fork (7) lower end also drives sliding sleeve (10) with its clamping along the parallel distance that moves of clutch spindle (12) to the right simultaneously.When diesel powered rotates clutch spindle (12) by Pulley, cover sliding sleeve (10) thereon also rotates thereupon, and sliding sleeve (10) is when moving to right, three tooth embeddings on the end face and finishing bevel gear cuter (11) end face three tooth embeddings engagement, finishing bevel gear cuter (11) is rotated, by giving screw propeller transmission of power with finishing bevel gear cuter (11) another finishing bevel gear cuter of ingear (9) and other drivings device, it is just changeed, then ship advances.
If handle (1) is pulled the A position, ship falls back (figure does not draw) just to make screw propeller reverse then.
The utility model is compared with prior art: because having adopted, this gear shift mechanism makes between shift fork and the declutch shift shaft, The Bidirectional locking of steel ball location between sliding sleeve and the clutch shaft makes the latching force multiplication, has changed on-hook shift machine Therefore the drawback of the easy trip stop of structure monodirectional locking has improved dependability and security. And simple in structure, tight Gather, easily handle and regulate. The design approximate vehicle handle gear shift of shift form, thereby shift is light and handy, comfortable, Various different use occasion users' different demands have been satisfied.
