Abstract
The invention discloses a clutch for a mini-tiller. The clutch for the mini-tiller comprises a clutch core and a clutch shell. A spring is arranged between the clutch core and the clutch shell. The clutch core and the clutch shell are provided with spline holes respectively. The clutch core is conical. At least one convex ring is arranged on the clutch core. Annular grooves matched with the convex rings are formed in the clutch shell. The section of each convex ring is trapezoidal. The clutch core and the clutch shell transmit power through the cooperation between the convex rings and the annular grooves. By the adoption of the clutch for the mini-tiller, the safety coefficient of the mini-tiller is increased, the transmitted torque is large, and the service life is long.
Description
Technical field
The present invention relates to function agricultural cultivator field; Specifically, the present invention relates to a kind of microtilling machine clutch.
Background technique
Microtilling machine with small diesel engine or petrol engine for power, the features such as have lightweight, volume is little, and structure is simple.Microtilling machine is widely used in the nonirrigated farmland, paddy field, orchard etc. on Plain, mountain area, hills.Mix corresponding facility can carry out drawing water, generate electricity, spray the operation such as medicine, spray, also can draw towed vehicle and carry out short-distance transport, microtilling machine freely can be exercised in field, user-friendly and deposit, eliminating the worry that large-scale farm machinery cannot enter mountain area field, is that vast farmers Consumer substitutes the cultivated optimal selection of ox.
At present, the clutch of microtilling machine is mostly normal-close clutch device, and during microtilling machine work, operator need Joystick to unclamp; When needs stop farming, operator need to hold handle, just can release handle after motor stops completely, when operator accidentally fall down or release handle time, microtilling machine can work on, and this brings potential safety hazard to operator.
Clutch relies on the frictional force of clutch core and clutch housing to carry out transmitting torque, and frictional force is not enough, causes clutch transmission torque to diminish.When load exceedes friction torque, clutch will skid, and affects the operation of microtilling machine, and it is serious to skid, and can produce a large amount of heat, makes clutch generation scaling loss.
Summary of the invention
The object of the present invention is to provide a kind of microtilling machine clutch, be normally disengaged clutch, comparatively high pulling torque can be transmitted.
Above-mentioned purpose of the present invention is achieved through the following technical solutions: microtilling machine clutch of the present invention, comprise clutch core and clutch housing, spring is provided with between described clutch core and clutch housing, described clutch core and clutch housing are respectively arranged with splined hole, described clutch core is taper, described clutch core is provided with at least one circle bulge loop, described clutch housing is provided with the annular groove matched with described bulge loop, the sectional shape of described bulge loop is trapezoidal, and described clutch core and clutch housing coordinate transferring power by bulge loop and annular groove.
Gap is left between the top of described bulge loop and the bottom of described annular groove.
The quantity of described bulge loop is 1 ~ 3.
Described clutch housing is provided with multiple radiation hole, and described radiation hole is arranged on sidepiece and/or the bottom of annular groove.
The assembly department of described clutch core is provided with the draw-in groove for installing back-up ring.
The microtilling machine clutch of the application of the invention, people, when ploughing, falls down, and his hand have left handle, and so machine has just stopped naturally, therefore improves the safety coefficient of microtilling machine, and transmitting torque is large, long service life.
Accompanying drawing explanation
With reference to accompanying drawing, disclosure of the present invention will be more obvious.Should understand, these accompanying drawings are only schematic, and not drawn on scale is also not intended to limit scope of the present invention.In figure:
Fig. 1 is the structural representation of microtilling machine clutch of the present invention;
Fig. 2 is the schematic diagram of the clutch core in Fig. 1;
Fig. 3 is the schematic diagram of the clutch housing in Fig. 1.
Embodiment
Explain the specific embodiment of the present invention with reference to the accompanying drawings.These explanations are only descriptive, exemplary.
See Fig. 1 ~ 3, microtilling machine clutch of the present invention, comprise clutch core 10 and clutch housing 20, spring 30 is provided with between described clutch core 10 and clutch housing 20, described clutch core 10 and clutch housing 20 are respectively arranged with splined hole 11, 21, described clutch core 10 is in taper, described clutch core 10 is provided with at least one circle bulge loop 12, described clutch housing 20 is provided with the annular groove 22 matched with described bulge loop 12, the sectional shape of described bulge loop 12 is trapezoidal, described clutch core 10 and clutch housing 20 coordinate transferring power by bulge loop 12 and annular groove 22.By described bulge loop 12 and the contact of annular groove 22, compare normal clutch and only have a rubbing surface, can surface of contact be expanded, thus increasing friction force.
Leave gap between the top of described bulge loop 12 and the bottom of described annular groove 22, after having made bulge loop 12 and/or annular groove 22 wear and tear, bulge loop 12 can be deep in annular groove 22 again, makes bulge loop 12 and annular groove 22 have good cooperation.As preferably, the quantity of described bulge loop 12 is 1 ~ 3.
Described clutch housing 20 is provided with multiple radiation hole 23.Radiation hole 23 be provided with the heat radiation being beneficial to clutch, improve the working life of clutch.Radiation hole 23 can be arranged on sidepiece and/or the bottom of annular groove 22.For being arranged on the sidepiece of annular groove 22 shown in figure.
The assembly department of described clutch core 10 is provided with the draw-in groove 13 for installing back-up ring.
As mentioned above, with reference to accompanying drawing, exemplary embodiments of the present invention has been described in detail.Should understand, the application is also not intended to make these details to form limiting the scope of the invention.When not deviating from according to the spirit and scope of the present invention, can carry out equivalent or similar change to the structure of exemplary embodiments and feature, these changes will also drop in the determined protection domain of appending claims of the present invention.
