Abstract
The utility model discloses a thrust disc assembly for a mini-tiller clutch. The thrust disc assembly comprises a thrust disc inner sleeve, wherein an integrated limiting ring table is arranged at one end of the thrust disc inner sleeve. The thrust disc assembly is characterized in that a pushing plate is sleeved on the thrust disc inner sleeve; assembly holes are uniformly formed on the pushing plate; the pushing plate is used as a rising plate and is connected with a pressing disc of a clutch by a bolt; a thrust ball bearing is sleeved between the limiting ring table and the pushing plate; an annular roller path matched with a steel ball of the thrust ball bearing is arranged on the pushing plate; and a limiting retainer ring is arranged on the thrust disc inner sleeve and is arranged on one side, opposite to the direction of thrust force, of the pushing plate. With the adoption of the thrust disc assembly, a thrust disc outer sleeve and the rising plate of the clutch in the prior art are replaced by the integrated pushing plate, so that the clutch is smoothly and completely separated, the separation characteristic of the clutch is improved, and the total weight of the clutch is reduced; and meanwhile, because of the replacement of components, production moulds are reduced, and the production cost is reduced.
Description
Technical field
The utility model relates to a kind of parts of Mini-tiller clutch, is specifically related to a kind of thrust disc assembly of Mini-tiller clutch.
Background technique
Existing thrust disc assembly comprises thrust disc inner sleeve and thrust disc overcoat; when hand is pinched clutch handle; by the separating mechanism on the casing power is passed to first the thrust disc inner sleeve; then promote the thrust disc overcoat; by the thrust disc overcoat power is passed to the clutch lift slab that central sleeve makes up again; by platen friction plate is separated with steel disc at last; and then realize that outer cover is combined on the splined shaft of power part and dally; not with transmission of power to the splined shaft on chassis; realize the gearshift of microtilling machine with this; transmitting torque; the effects such as overload protection; but because the bearing that a plurality of parts such as thrust disc assembly and clutch lift slab and thrust disc assembly have adopted low precision has been passed through in the thrust transmission of this process; cause the part quality of fit low; the clutch separation characteristic is poor; in addition, also to have a running noise large for clutch; the shortcomings such as weight is heavier.
Summary of the invention
The purpose of this utility model is the problem for above-mentioned technology existence, a kind of thrust disc assembly of Mini-tiller clutch is provided, guaranteeing under the prerequisite that clutch working strength, normal function are realized, improve clutch stalling characteristic, alleviate clutch weight, reduce its running noise.
To achieve these goals, the technical solution adopted in the utility model is as follows: a kind of thrust disc assembly of Mini-tiller clutch, comprise the thrust disc inner sleeve, be provided with the limited ring dais that is connected as a single entity at thrust disc inner sleeve one end, it is characterized in that: in described thrust disc, put a push pedal, be provided with equably pilot hole in push pedal, described push pedal is bolted as the platen of lift slab and clutch; Cover has thrust ball bearing between described limited ring dais and push pedal, is provided with the ring raceway that cooperates with the steel ball of thrust ball bearing in push pedal; In described thrust disc, put and be provided with spacing back-up ring in the side relative with thrust direction of push pedal.
Described thrust ball bearing is the standard rolling bearing with annular retainer.
The utility model is because the all-in-one-piece push pedal of employing replaces two parts of lift slab of thrust disc overcoat of the prior art and clutch and adopt high-precision thrust ball bearing with retainer to replace the bearing that hangs down precision, so that the separation of clutch is more smooth and easy, thorough, improved the stalling characteristic of clutch, alleviate the quality of thrust disc assembly, and then alleviated the clutch gross weight; Simultaneously, because the replacement of part has reduced cost of production so that production mould reduces.

Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1, a kind of thrust disc assembly of Mini-tiller clutch, comprise thrust disc inner sleeve 1, be provided with the limited ring dais 11 that is connected as a single entity at thrust disc inner sleeve 1 one ends, at described thrust disc inner sleeve 1 cover one push pedal 2 is arranged, be provided with equably pilot hole 21 in push pedal 2, described push pedal is bolted as the platen of lift slab and clutch; Shown in Fig. 2 a, 2b, 2c, 2d, the quantity of pilot hole is 4-8, also can be other quantity, on the platen of its quantity and clutch accordingly bolt hole equate; Cover has thrust ball bearing 3 between described limited ring dais 11 and push pedal 2, is provided with the ring raceway 22 that cooperates with the steel ball 31 of thrust ball bearing 3 in push pedal 2; In described thrust disc, put and be provided with spacing back-up ring 4 in the side relative with thrust direction of push pedal.
With the thrust disc overcoat 5 on the all-in-one-piece push pedal 2 alternative existing thrust disc assemblies and the clutch lift slab 6 in the central sleeve combination, such as Fig. 1, shown in Figure 3, like this, reduced the thrust transmittance process, so that the quality of fit between the part improves, so that the separation of clutch is more smooth and easy, thorough, improved the stalling characteristic of clutch.
Described thrust ball bearing 3 is the standard rolling bearing with annular retainer.Substitute the low loose bearings 7 that will have now on the thrust disc assembly with the high-precision thrust ball bearing 3 with retainer, such as Fig. 1, shown in Figure 3, by retainer 32 that the steel ball that rolls is equally spaced, avoided collision and friction between the steel ball, the noise when having reduced the clutch running.
When hand is pinched clutch handle; by the separating mechanism on the casing power is passed to first limited ring dais 11; then directly pass to push pedal 2 through thrust ball bearing 3; by platen friction plate is separated with steel disc at last; and then realize that outer cover is combined on the splined shaft of power part and dally; not with transmission of power to the splined shaft on chassis, realize the effect such as gearshift, transmitting torque, overload protection of microtilling machine with this.
This uses novel described thrust disc assembly when mounted, the thrust disc assembly is fixed on the Mini-tiller clutch platen through pilot hole 21 by bolt.
