Embodiment

Describe below in conjunction with the preferred embodiment of accompanying drawing, should be appreciated that preferred embodiment described herein only is used for explanation and explains the utility model, and be not used in qualification the utility model the utility model.

The utility model is used on the farm machinery.

Like Fig. 4, Fig. 5, shown in Figure 6, the part of clutch shaft has spline, like Figure 12, shown in Figure 13; There is spline driven cover 5 inside; Driven cover 5 is sleeved on the clutch shaft 1 spline position, the two can not be relatively rotated but can horizontally slips, the cylindrical of driven cover 5 is installed bearing 4 and right outer combined cover 3; Right outer combined cover 3 is connected with rotational arm of clutch 2 usefulness bolts 14, makes driven cover 5 and right outer combined cover 3 be in the state that can relatively rotate;

With the cylindrical bearing set 8 and left combined cover 13 that initiatively overlap 6, initiatively overlap 6 inner rings and nylon jacket 12 assemblings, and guarantee drive fit between the two, the two is sleeved on the clutch shaft 1 (guarantees nylon jacket 12 and clutch shaft 1 Spielpassung) then;

The outer combined cover 13 in a left side that installs is connected with clutch base 7 usefulness bolts on being fixed on body, makes left outer combined cover 13 and clutch base 7 be in relative static conditions, initiatively overlap 6 and clutch shaft 1 be in the state of relatively rotating;

With 9 assemblings of power input sprocket, the two can not relatively rotate on the step that initiatively overlaps 6 left ends;

High order end assembling power output sprocket 10 at clutch shaft 1 connects with key 11 between the two, and when guaranteeing that clutch shaft 1 rotates, power drives to other position of machine through power output sprocket 10;

Spring 17 is enclosed within clutch shaft 1 right-hand member, and bearing 16 is installed, like Fig. 1, Fig. 2, shown in Figure 3 at right spindle nose.

Bearing 16 is connected with the body of farm machinery.

During work; Power is through power input sprocket 9 input, drives to be assemblied in initiatively overlap on the clutch shaft 1 and 6 to rotate, and operation pull bar 15 and then pulling rotational arm of clutch 2 are clockwise or rotate counterclockwise; Rotational arm of clutch 2 drives right outer combined cover 3 and rotates; Make the outer combined cover 13 tooth embeddings engagement in a right outer combined cover 3 and a left side, while spring 17 promotes rotational arm of clutch 2, right combined cover 3 and driven cover 5 and slides left, makes the three equal parts teeth on the driven cover 5 carry out tooth embedding engagement with the teeth of initiatively overlapping 6; Thereby driving driven cover 5 rotates; Driven cover 5 drives clutch shaft 1 through the spline on the clutch shaft 1 again and rotates, and then drives power output sprocket 10 rotations on the clutch shaft 1, and power output sprocket 10 reaches other parts that need rotate on the machine with power again.

When needs cut off power, operation pull bar 15 and then pulling rotational arm of clutch 2 clockwise or rotate counterclockwise, rotational arm of clutch 2 drives right combined cover 3 and rotates; Because the left combined cover 13 that is fixed on the clutch base 7 is static; Teeth on the right clutch cover 3 relatively rotate, and become separated state by engagement, promote and the driven cover 5 that is assembled together slides to the right; Make driven cover 5 and the teeth of initiatively overlapping 6 become separated state by engagement; At this moment right combined cover 3 is the state of relatively rotating with driven cover 5, and power is cut off, and mechanically needs out-of-work part to quit work thereby make.

A kind of clutch of the utility model, lighter and handier than chuck mode clutch, easy to use, reliable operation.

What should explain at last is: the above is merely the preferred embodiment of the utility model; Be not limited to the utility model; Although the utility model has been carried out detailed explanation with reference to previous embodiment; For a person skilled in the art, it still can be made amendment to the technological scheme that aforementioned each embodiment put down in writing, and perhaps part technical characteristics wherein is equal to replacement.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
