Abstract
The utility model relates to a device with a slanted ratchet pawl for an automatic synchronizing clutch, consisting of outer teeth of driving teeth, inner teeth of the driving teeth, a sliding piece, an input piece, spline teeth, an output end flange, an output piece, a pawl, a ratchet and an input end flange, wherein the inclined plane angle p ratcheted by the ratchet and the pawl is larger than 0 degree and is smaller than or equal to 20 degrees. The novel structure changes a molded line at the heat of the pawl from the conventional straight line to an inclined line, and the ratchet teeth are also changed from the straight line into the inclined line ratcheted and meshed with the ratchet teeth. Therefore, the ratcheting of the ratchet and the pawl is carried out, so that the guiding to slave driving teeth is also carried out along the inclined surface. Therefore, the meshing process of a working surface of the slave driving teeth is changed from sudden conduction into gradual conduction, gaps among the teeth are gradually eliminated, so that the phenomenon that the meshed teeth are contacted suddenly to generate collision like linear positioning and guiding is avoided. The device improves the safety and maintenance for use of the clutch and reduces the maintenance cost.
Description
Affiliated technical field
The utility model relates to a kind of clutch, specifically is meant the device that plays the click with bias type of synchronous positioning action in can self-synchronizing clutch.
Background technique
At present, self-synchronizing clutch has been widely used in military products, chemical industry, metallurgy, every field such as energy-conservation, and the working principle of self-synchronizing clutch is automatically to realize engaging, throwing off according to the rotating speed of master and slave moving axis.Clutch is in engaging process, and when click is thrown off rapidly, clutch driving gear (interior external tooth) must move rapidly along circumference, makes the contact of tooth working surface by the jail.Because flank has big gap, and it is big to mesh differential angular acceleration, clutch can produce bigger bump in engagement process.The bump that causes during self-synchronizing clutch synchromesh is a very important problem, and it is related to the working life of clutch and influences the power plant performance of handoffs, so this is the problem that clutch designs must solve.
Summary of the invention
In order to solve the bump that when engagement produces, the utility model provides a kind of novel ratchet ratchet to replace conventional click, has reduced impact during clutches engaged after the improvement, has eliminated bump.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind ofly be used for the device that self-synchronizing clutch has the bias type click, be by driving gear external tooth (1), driving gear internal tooth (2), sliding component (3), input component (4), spline tooth (5), output terminal flange (6), output member (7), ratchet (8), ratchet (9) and input end flange (10) are formed, described output terminal flange (6) links to each other with output member (7), input end flange (10) links to each other with input component (4), input component (4) links to each other with sliding component (3) by spline tooth (5), be equipped with driving gear external tooth (1) on the sliding component (3), be equipped with driving gear internal tooth (2) on the input component (4), ratchet (9) places on the sliding component (3), and ratchet (8) places on the output member (7); Described ratchet (9) and ratchet (8) the sour jujube angle of tilt p scope of closing mutually are 0＜p≤20 °.
On the basis of the conventional click of self-synchronizing clutch, change the molded lines of ratchet head into oblique line by straight line, thereby hook tooth also by straight line change into ratchet mutually sour jujube close the oblique line that coincide.The sour jujube of click is closed along the inclined-plane and carries out like this, thereby also is to carry out along the inclined-plane to the guiding of driven driving gear (interior external tooth).This makes driven driving gear working surface engagement process be undertaken by becoming suddenly gradually, and backlash is eliminated gradually, unlike straight line type location and guiding, engaging tooth is contacted suddenly, produces bump.
The beneficial effects of the utility model are that by conventional click being changed into the novel ratchet ratchet with slope, the bump when having eliminated clutches engaged has improved Security and maintenance that clutch uses, has reduced maintenance cost.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model structure axial position schematic diagram.
Fig. 2, Fig. 4, Fig. 5, Fig. 6 and Fig. 7 are the utility model arrangement works process schematic representation.
Fig. 3 is ratchet and the ratchet schematic representation of the fashionable angle of tilt p of sour jujube mutually of this mechanism.
Fig. 8 is the throw-out-of clutch figure of present embodiment.
Fig. 9 is the clutch figure of present embodiment.
Embodiment
Further specify with reference to the accompanying drawings, in Fig. 8 embodiment: output terminal flange (6) links to each other with output member (7), input end flange (10) links to each other with input component (4), input component (4) links to each other with sliding component (3) by spline tooth (5), sliding component (3) upper arm has driving gear external tooth (1), be equipped with driving gear internal tooth (2) on the input component (4), ratchet (9) places on the sliding component (3), and ratchet (8) places on the output member (7).The center line top is throw-out-of clutch figure, and the center line below is clutch figure.
When input component (4) and output member (7) synchronization and when the trend of surmounting is arranged, ratchet (9) on the sliding component (3) will withstand the ratchet (8) on the output member (7), be that click produces sour jujube cooperation usefulness, input component (4) is for the helical movement relatively along spline tooth (5) to impel sliding component (3), be that the relative output member (7) of sliding component (3) axially moves, make inside and outside driving gear (1,2) enter engagement, and tooth and tooth are close to clutch.Otherwise be in the clutch of jointing state, when the relative output member (7) of input component (4) slows down, the active force between output member (7) and the sliding component (3) will make the slippage group do reverse spiral motion, thereby clutch is thrown off automatically.
At Fig. 1 is click axial position figure schematic diagram, and Fig. 2 is the sectional drawing of driving gear and click among Fig. 1, and its angle of tilt p embodies in its section.A and b are the gaps of driving gear external tooth and driving gear internal tooth teeth groove, and angle p is exactly the angle of tilt of ratchet and pawl.
Fig. 4 and Fig. 5 are that click is thrown off, and the driving gear external tooth has entered in the driving gear internal tooth teeth groove.
Fig. 6 and Fig. 7 are that driving gear meshes fully, and click is thrown off fully.
By Fig. 2-Fig. 7, can reflect clearly that the gap that click changes inclined-plane rear driving tooth into eliminates process gradually.
