Description
Technical field
The present invention relates to a kind of clutch device, refer more particularly to a kind of for clutch self-detaching speed regulator.
Background technique
As everyone knows, clutch is used widely in automotive field, but is also widely using in other transmission device.In the transmission devices such as automobile, the clutch of clutch is the disengagement that is contacting and separating being promoted clutch by people to an external force.But in the industries such as Aero-Space use, bring into use a generator starting equipment to start to start main frame, after main frame reaches self-sustain speed, starting equipment needs instant disengagement automatically.This external force has been come by a mechanism or device.The mechanism used in current technology or device adopt friction plate, spring or roller.Friction plate easily by temperature, humidity effect, for the equipment that rotational speed regulation scope is larger, uses more, regulates also comparatively frequent.Aerospace main frame also uses roller, spring as the engaging and disengaging gear of clutch, roller is difficult to carry out adjustment of rotational speed.Pre-set self-detaching adjustment of rotational speed with spring, but difficulty is comparatively large, first needs to select suitable spring to adjust, need the spring producing a series of different elastic force, cause very large waste, increase cost; Secondly, in the spring of a series of fixing elastic force, there is interval in the size of elastic force, discontinuous, and therefore, the change of throwing off rotating speed is interrupted; Again, when regulating at every turn, whole device need be taken apart completely, not only damage the quality of fit between part, and operation inconvenience, extremely loaded down with trivial details.
Summary of the invention
Object of the present invention is exactly deficiency for above-mentioned existence and designs a kind of for clutch self-detaching speed regulator.
For achieving the above object, the present invention by the following technical solutions: a kind of clutch self-detaching speed regulator that is used for comprises clutch housing, splined shaft, spiral spring, chock, stop pin, snap ring, ratchet.Splined shaft is connected with clutch housing by spline tooth, and is fixed on clutch housing by chock.Spiral spring one end is fixed on splined shaft, and the other end is fixed on chock.Ratchet is arranged on the central position of clutch housing, by the active force of spiral spring, chock front end is withstood in the teeth groove of ratchet surface.Clutch housing is provided with stop pin, is used for blocking the pivotal position when after chock front end throws off the teeth groove of ratchet automatically under centrifugal action.
Described chock is a wedge shape, is a groove around middle mounting hole, and chock front end is long and sharp, and chock rear end is short and wide.Chock ear end face has the end face limit point in a S shape face.
Annulus is evenly equipped with on described clutch housing top the internal spline of 3-4 installation splined shaft 2, the uniform 3-4 in internal spline position installation spline axis hole of corresponding upper annulus on upper subordinate's annulus.Chock is arranged between annulus, lower annulus, positions installation with splined shaft.The outer side wall of clutch housing has a rectangular opening, rotation space when to contact with the teeth groove of ratchet for chock and throw off, and when the limit point of chock ear end face turns to the rectangular opening limit place of hull outside wall, chock is limited.
Described splined shaft inserts the internal spline on clutch housing, by chock location and installation between the upper annulus and lower annulus of clutch housing, is meshed with the internal spline on clutch housing by the external spline teeth of splined shaft, is used for the autorotation of restriction splined shaft.The axial float that a snap ring blocks splined shaft is installed at the top of splined shaft, the axial position of splined shaft has had the straight trough that identical with spiral spring steel wire diameter.
Described spiral spring is for a kind of standard Spring Steel Wire is made, and comprises insertion part, scrollwork, buckle hanging unit.The insertion part of spiral spring and the horizontal sextant angle of scrollwork are 90 °, and scrollwork forms according to similar involute dish system, and buckle hanging unit is a S shape.The insertion part of spiral spring is inserted in the straight trough of splined shaft, and scrollwork is sleeved on splined shaft, and the buckle hanging unit of spiral spring buckles in chock front end.
The debugging of described spiral spring, the first step, pulls down snap ring; Second step, extracts splined shaft out, throws off, be then rotated counterclockwise splined shaft until be connected with the spline tooth of clutch housing, increases the initial elastic force of spiral spring.Now, elastic force increases, and the centrifugal force overcome needed for elastic force increases, and throws off rotating speed and increases.Otherwise when reducing to throw off rotating speed, turn clockwise splined shaft, the elastic force of spiral spring reduces, and the centrifugal force overcome needed for elastic force reduces, and throws off rotating speed and reduces.
Beneficial effect of the present invention is:
When this device does not work, chock front end relies on spiral spring to withstand the ratchet of starting equipment.During starting, the moment of torsion of starting equipment passes to chock by ratchet, and then passes to clutch housing, and continues going down.When starting equipment disconnects, chock front end relies on centrifugal force to compress stop pin.When stopping, spiral spring overcomes centrifugal force, makes chock front end leave stop pin, and withstands the ratchet of starter motor, and from now quitting work to main frame, will skid along the hook tooth of starting equipment in chock front end.
Development results shows: scroll spring elastic force makes chock compress ratchet, and clutch housing rotates the centrifugal force produced makes chock away from ratchet, when centrifugal force is greater than elastic force, chock away from ratchet, near stop pin; When centrifugal force is less than elastic force, chock is near ratchet, away from stop pin, respond well.
