Abstract
The invention relates to a centrifugal clutch. The centrifugal clutch comprises a driving shaft, a ratchet wheel, a driven component, a pawl and a volute spiral spring, wherein the ratchet wheel is fixedly installed on the driving shaft, the pawl is installed on the driven component through a shaft, one end of the volute spiral spring is fixed to the shaft, the other end of the volute spiral spring is clamped on the ratchet wheel, the shaft is provided with an outer spline, and an inner spline is arranged on a hole in an installation shaft on the driven component and is matched with the outer spline on the shaft. The centrifugal clutch is wide in application range, is convenient to operate when used for the work environment not affected by change of the rotation speed, does not need to design and machine components again, and achieves the purposes of saving manpower, material resources and cost.
Description
Technical field
The present invention relates to a kind of clutch, especially a kind of centrifugal clutch.
Background technique
Clutch is a kind of common actuating unit structure, and of a great variety, and only mechanical clutch just can be divided into safety clutch, free wheel device, centrifugal clutch etc.Centrifugal clutch is comparatively common, be by driven member ratchet is set and be stuck in driving shaft on the ratchet that is connected, in the time that driven member reaches certain rotating speed, ratchet is used self centrifugal force, throw off with ratchet, realize the clutch function of driven member and driving shaft.But this structure is because throwing off rotating speed fixes, and purposes is single, can not adapt to the usage requirement of multi-operating mode.When according to actual conditions, when disengagement rotating speed changes, the mass distribution of ratchet or new clutch mechanism be need to reset, a large amount of human and material resources and cost wasted.
Summary of the invention
The object of this invention is to provide a kind of centrifugal clutch, can adjust within the specific limits throw-out-of clutch rotating speed according to need of work, reach using scope wide, and save the object of human and material resources and cost.
Technological scheme of the present invention is, centrifugal clutch comprises driving shaft, ratchet, driven member, ratchet, spiral spring, ratchet is fixedly mounted on driving shaft, ratchet is arranged on driven member by axle, ratchet can sway, and spiral spring one end is fixed on axle, and the other end is stuck on ratchet, on the elastic card of ratchet dependence spiral spring, on ratchet, on ratchet, the center of installation shaft is greater than the quality of opposite side to the quality between ratchet and ratchet point of contact; Described axle is provided with external splines, is provided with internal spline and coordinates with the external splines on axle on the hole of driven member installation shaft; On driven member, be also provided with position limit pin.Described ratchet is uniform three.
The present invention is provided with spiral spring, on axle, be provided with spline simultaneously, when use, can adjust the setting angle of axle, because fixed one end of spiral spring on axle, adjust the setting angle of axle and just can make the elasticity of spiral spring change in certain scope, thereby the disengage speed that has realized ratchet can be adjusted within the specific limits.In addition, by the indexs such as the modulus of spline are set, can realize different adjustment precision.Applicable scope of the present invention is large, for throwing off the working environment of rotation speed change, easy to operate, does not need again parts to be designed and processed, and has reached the object of having saved human and material resources and cost.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in the figure, centrifugal clutch comprises driving shaft, ratchet 2, driven member 1, ratchet 6, spiral spring 4, ratchet 2 is fixedly mounted on driving shaft, ratchet 6 is arranged on driven member 1 by axle 5, ratchet 6 can rotate around axle 5, and spiral spring 4 one end are fixed on axle 5, and the other end is stuck on ratchet 2, ratchet 6 relies on the elastic card of spiral spring 4 on ratchet 2, and on ratchet 6, the center of installation shaft is greater than the quality of opposite side to the quality between ratchet 6 and ratchet 2 point of contact; Described axle 5 is provided with external splines, is provided with internal spline and coordinates with the external splines on axle 5 on driven member 1 on the hole of installation shaft 5; On driven member 1, be also provided with position limit pin 3.Described ratchet 6 is uniform three.
