For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: a kind of rotovator that adopts clutch apparatus is provided; Clutch apparatus comprises: active part, secondary part, said active part comprise that initiatively clutch discs, ball dish, said ball dish are through a bearing and said coaxial connection of active clutch discs, and said secondary part comprises driven clutch discs; Said active clutch discs and driven clutch discs are oppositely arranged; Said ball dish comprises ball Moving plate, the quiet dish of ball, is provided with a plurality of balls between said ball Moving plate and the quiet dish of ball, and the quiet dish of said ball is provided with first ball grooves of placing ball; Said first ball grooves along ball disc spins direction by being deep to shallow setting; Said ball Moving plate is provided with second ball grooves with said first ball grooves coupling, is connected with clutch line, return unit on the said ball Moving plate, and the direction of motion of said clutch line and return unit is opposite.
In preferred embodiment of the utility model, be coaxially connected with driving shaft on the said active clutch discs.
In preferred embodiment of the utility model, said driven clutch discs is fixedly installed on one from the dynamic friction foundry goods, saidly is coaxially connected with driven shaft from the dynamic friction foundry goods.
In preferred embodiment of the utility model, said driven clutch discs be fixedly connected through a plurality of rivets between the dynamic friction foundry goods.
In preferred embodiment of the utility model, said ball is a steel ball.
In preferred embodiment of the utility model, said return unit is a reset tension spring.
The beneficial effect of the utility model is: the rotovator of the employing clutch apparatus of the utility model adopts roll structure to realize separation and combination between the clutch discs, has reduced noise, has reduced wearing and tearing; Simple and reliable for structure, easy to assembly, reasonable price.
Description of drawings
Fig. 1 is the structural representation of clutch apparatus one preferred embodiment of the utility model rotovator of adopting clutch apparatus;
Fig. 2 is the explosive view of clutch apparatus shown in Figure 1;
The mark of each parts is following in the accompanying drawing: 1, clutch discs initiatively, 2, driven clutch discs, 3, from the dynamic friction foundry goods, 4, bearing; 5, ball Moving plate, 6, the quiet dish of ball, 7, ball, 8, first ball grooves; 9, second ball grooves, 10, the clutch line, 11, return unit; 12, driving shaft, 13, driven shaft, 14, rivet.
Embodiment
Below in conjunction with accompanying drawing the preferred embodiment of the utility model is set forth in detail, thereby the protection domain of the utility model is made more explicit defining so that advantage of the utility model and characteristic can be easier to it will be appreciated by those skilled in the art that.
See also Fig. 1 and Fig. 2, the utility model embodiment comprises:
A kind of rotovator that adopts clutch apparatus, clutch apparatus comprises: active part, secondary part.
Said active part comprises initiatively clutch discs 1, ball dish.Said ball dish is through a bearing 4 and said 1 coaxial connection of active clutch discs.Be coaxially connected with driving shaft 12 on the said active clutch discs 1.
Said secondary part comprises driven clutch discs 2, and said driven clutch discs 2 is fixedly installed on one from dynamic friction foundry goods 3 through a plurality of rivets 14, saidly is coaxially connected with driven shaft 13 from dynamic friction foundry goods 3.
Said active clutch discs 1 is oppositely arranged with driven clutch discs 2.
The clutch apparatus of the utility model is applicable to vertically shafted engine, and is simple and reliable for structure, easy to assembly, applied widely.
Said ball dish comprises ball Moving plate 5, the quiet dish 6 of ball; Be provided with a plurality of balls 7 between the quiet dish 6 of said ball Moving plate 5 and ball; The quiet dish 6 of said ball is provided with first ball grooves 8 of placing ball 7; By being deep to shallow setting, said ball Moving plate 5 is provided with second ball grooves 9 with said first ball grooves, 8 couplings to said first ball grooves 8 along ball disc spins direction.Said ball 7 is a steel ball.
Be connected with clutch line 10, return unit 11 on the said ball Moving plate 5, said clutch line 10 is opposite with the direction of motion of return unit 11.Said return unit 11 is a reset tension spring.
Wherein the direction of draw of clutch line 10 is the direction of rotation of ball dish; The direction of rotation of the rebound direction of return unit 11 and ball dish is opposite; Through ball 7 in the ball dish by being deep to shallow rolling back and forth, promote initiatively that clutch discs 1 moves up and down, thereby reach and driven clutch discs 2 combines and the functions of separating; Reduce noise, reduced wearing and tearing.
The clutch apparatus of the utility model adopts ball 7 structures to realize separation and combination between the clutch discs, has reduced noise, has reduced wearing and tearing, and is simple and reliable for structure, easy to assembly, reasonable price.
