Abstract
The invention discloses a rotational speed adjusting device for automatically disengaging a clutch. The rotational speed adjusting device for automatically disengaging the clutch comprises a clutch shell, a spline shaft, a volute spiral spring, a stop block, a snap ring and a ratchet wheel. The spline shaft is connected with the clutch shell through a spline tooth, and fixes the stop block on the clutch shell. One end of the volute spiral spring is fixedly arranged on the spline shaft, while the other end of the volute spiral spring is fixedly arranged on the stop block. The ratchet wheel is mounted at the central position of the clutch shell, and stop block front ends are enabled to be pushed in tooth grooves in the surface of the ratchet wheel through the acting force of the volute spiral spring. The stop pin is mounted on the clutch shell, and is used for blocking a rotation position under the action of centrifugal force after the stop block front ends automatically disengage from the tooth grooves of the ratchet wheel. Shown by development results, the elastic force of the volute spiral spring makes the stop block tightly press the ratchet wheel; the centrifugal force generated by the rotation of the clutch shell makes the stop block be far away from the ratchet wheel; when the centrifugal force is more than the elastic force, the stop block is far away from the ratchet wheel, and approaches the stop pin; when the centrifugal force is less than the elastic force, the stop block approaches the ratchet wheel, and is far away from the stop pin; and the effect is favorable.
Description
Technical field
The present invention relates to a kind of clutch apparatus, refer more particularly to a kind of for clutch self-detaching rotating speed
Adjusting apparatus.
Background technology
It is known that clutch is used widely in automotive field, but in other actuating device also
It is being widely used.In the actuating devices such as automobile, the clutch of clutch is to promote clutch by people to an external force
The disengagement that is contacting and separating of device.But in the industries such as Aero-Space use, begin to use a generator starting
Equipment starts to start main frame, and after main frame reaches self-sustain speed, starting equipment needs instant the most de-
Open.This external force is completed by a mechanism or device.The mechanism used in current technology or device
It is to use friction plate, spring or roller to complete.Friction plate is easily affected by temperature, humidity, for
For the equipment that rotational speed regulation scope is bigger, use more, regulate the most frequent.Aerospace main frame
On also use roller, spring to be difficult to adjustment of rotational speed as the arrangement of clutch of clutch, roller.Use spring
Pre-set self-detaching adjustment of rotational speed, but difficulty is bigger, it is necessary first to select suitable spring to carry out
Adjust, need to produce the spring of a series of different elastic force, cause the biggest waste, increase into
This；Secondly, in the spring of a series of fixing elastic force, the size existence interval of elastic force, discontinuously, therefore,
The change disengaging rotating speed is to be interrupted；Again, when regulating, whole device need to be taken apart completely, not only every time
Damage the quality of fit between part, and operate inconvenience, the most loaded down with trivial details.
Summary of the invention
The purpose of the present invention is aiming at the deficiency of above-mentioned existence and designs one and automatically disengage for clutch
Speed regulator.
For achieving the above object, the present invention is by the following technical solutions: a kind of clutch self-detaching that is used for turns
Velocity modulation engagement positions includes clutch housing, splined shaft, scroll spring, scotch, latch, snap ring, spine
Wheel.Splined shaft is connected with clutch housing by spline tooth, and is fixed on clutch housing by scotch.
Scroll spring one end is fixed on splined shaft, and the other end is fixed on scotch.Ratchet is arranged on bell housing
The center of body, makes scotch front end withstand in the teeth groove of ratchet surface by the active force of scroll spring.
Clutch housing is provided with latch, is used for blocking after scotch front end disengages the teeth groove of ratchet automatically
Turned position under centrifugal action.
Described scotch is a wedge shape, is a groove around middle installing hole, and scotch front end is
Long and sharp, scotch rear end is short-wide.Scotch rear end face has the end face limit point in a S-shaped face.
The internal spline of 3-4 installation splined shaft 2 it is evenly equipped with on annulus on described clutch housing top, on
Uniform 3-4 the installation spline axis hole in internal spline position of corresponding upper annulus on subordinate's annulus.Scotch is arranged on
Between upper annulus, lower annulus, carry out location and installation with splined shaft.The lateral wall of clutch housing has
One rectangular opening, the rotation space when scotch contacts with the teeth groove of ratchet and disengages, and at scotch
When the limit point of rear end face turns at the rectangular opening limit of hull outside wall, scotch is limited.
Described splined shaft inserts the internal spline on clutch housing, by scotch location and installation at bell housing
Between upper annulus and the lower annulus of body, by the external spline teeth of splined shaft and the internal spline phase on clutch housing
Engagement, is used for limiting the autorotation of splined shaft.It is mounted with that at the top of splined shaft a snap ring blocks splined shaft
Axial float, the axial location of splined shaft has a straight trough identical with scroll spring steel wire diameter.
Described scroll spring is to make, including insertion section, scrollwork, buckle hanging unit for a kind of standard spring steel wire.
The insertion section of scroll spring and the horizontal sextant angle of scrollwork are 90 °, and scrollwork forms according to similar involute dish system,
Buckle hanging unit is a S-shaped.The insertion section of scroll spring is inserted in the straight trough of splined shaft, and scrollwork is sleeved on spline
On axle, the buckle hanging unit of scroll spring buckles in scotch front end.
The debugging of described scroll spring, the first step, pull down snap ring；Second step, extracts splined shaft out, until with
The spline tooth of clutch housing connects disengagement, rotates splined shaft the most counterclockwise, increases the initial of scroll spring
Elastic force.Now, elastic force increases, and overcomes the centrifugal force needed for elastic force to increase, and disengages rotating speed and increases.Otherwise,
When to reduce disengagement rotating speed, turn clockwise splined shaft, and the elastic force of scroll spring reduces, and overcomes elastic force institute
The centrifugal force needed reduces, and disengages rotating speed and reduces.
The beneficial effects of the present invention is:
When this device does not works, scotch front end relies on scroll spring to withstand the ratchet of starting equipment.During starting,
The moment of torsion of starting equipment passes to scotch by ratchet, passes to clutch housing the most again, and continue to
Lower transmission.When starting equipment disconnects, scotch front end relies on centrifugal force to compress latch.When stopping, whirlpool
Coil spring overcomes centrifugal force, makes scotch front end leave latch, and withstands the ratchet of starter, from now
Quitting work to main frame, will skid along the hook tooth of starting equipment in scotch front end.
Development results shows: scroll spring elastic force make scotch compress ratchet, clutch housing rotate produce from
Mental and physical efforts make scotch away from ratchet, and when centrifugal force is more than elastic force, scotch is away from ratchet, near latch；
When centrifugal force is less than elastic force, scotch is near ratchet, away from latch, respond well.
