Abstract

The invention discloses a synchronous automatic clutch with a high-speed pawl mechanism and a low-speed pawl mechanism. The synchronous automatic clutch is characterized in that an input shaft is connected with a slide assembly by external spiral teeth and internal spiral teeth, external driving teeth of the slide assembly and internal driving teeth of an output toothed ring are meshed and connected with one another by a gear, a low-speed ratchet is arranged on an outer circle of the slide assembly, a low-speed pawl is arranged at an inner hole in the output toothed ring, a high-speed ratchet is arranged at an inner hole in the other end of the output toothed ring, a high-speed pawl is arranged at the outer circle of the slide assembly, the input shaft is connected with the slide assembly by the external spiral teeth and the internal spiral teeth, the internal driving teeth are connected and meshed with the external driving teeth when the input shaft and the slide assembly rotate relatively towards a direction in place, and the internal driving teeth are separated from the external driving teeth meshed with the internal driving teeth when the input shaft and the slide assembly rotate relatively in another direction in place. The synchronous automatic clutch has the advantages that a conventional synchronous automatic clutch is modified to obtain the synchronous automatic clutch with the two ratchet and pawl mechanisms, accordingly, the service safety can be improved, and the maintenance cost can be reduced.

Description

The synchronous automatic clutch of detent mechanism is overlapped with high low speed two
technical field:
The present invention relates to mechanical transmission fields, specifically a kind of synchronous automatic clutch overlapping detent mechanism with high low speed two.
background technique:
At present, self-synchronizing clutch has been widely used in military products, chemical industry, metallurgy, the every field such as energy-conservation, and the working principle of self-synchronizing clutch automatically realizes engaging, throwing off according to the rotating speed of master and slave moving axis.When the clutch is disengaged, click is in free wheel state; When clutch engages and starts, ratchet head withstands on hook tooth and produces sour jujube cooperation use, helical spline tooth produces axial force and promotes middle sliding component axial slip, driving external tooth is entered into and drives internal tooth teeth groove, driving gear plasmid conjugation power, click completes synchronous positioning action.Ratchet and pawl arrangement is the important portion cover of clutch, and its sour jujube conjunction action is the beginning of synchronous automatic clutch generation joint action, plays synchronous positioning action.But for the occasion that operating rotational speed range is very large, a set of ratchet and pawl arrangement can cause the heavy wear of ratchet when throw-out-of clutch, even impact failure, therefore, can the design problem of synchronous automatic clutch click of engagement/disengagement when must solve any rotating speed.
summary of the invention:
In order to ensure that clutch can engage when any rotating speed, the invention provides a kind of synchronous automatic clutch with two cover ratchet and pawl arrangements and replacing conventional synchronous automatic clutch.
Technological scheme of the present invention is: the synchronous automatic clutch overlapping detent mechanism with high low speed two, comprise input shaft, be connected by helical tooth external tooth and helical tooth internal tooth between input shaft with sliding assembly, connected by gears meshing between the outer driving gear of sliding assembly and the interior driving gear exporting ring gear, the cylindrical of sliding assembly is provided with low speed ratchet, the endoporus place of the output ring gear of low speed ratchet relevant position is provided with low speed ratchet, the other end endoporus place exporting ring gear is provided with high speed ratchet, and the cylindrical place of the sliding assembly of high speed ratchet relevant position is provided with high speed ratchet.
Described input shaft is connected by helical tooth external tooth and helical tooth internal tooth with between sliding assembly, when an input shaft direction relative to sliding assembly is rotated in place, interior driving gear engages with outer driving gear and engages, when input shaft another direction relative to sliding assembly is rotated in place, interior driving gear is thrown off with outer driving gear and is engaged.
The present invention has following beneficial effect: by being made into by the synchronous automatic clutch of routine, with the synchronous automatic clutch of two cover ratchet and pawl arrangements, to improve the Security of use, reduce maintenance cost.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention;
Fig. 2 ~ Fig. 5 is working procedure schematic diagram of the present invention.
1-input shaft in figure, 2-helical tooth external tooth, 3-helical tooth internal tooth, 4-sliding assembly, 5-low speed ratchet, 6-low speed ratchet, 7-exports ring gear, 8-high speed ratchet, 9-high speed ratchet, driving gear in 10-, the outer driving gear of 11-.
embodiment:
Below in conjunction with accompanying drawing, the invention will be further described:
Shown in Fig. 1 composition graphs 2 ~ Fig. 5, the synchronous automatic clutch of detent mechanism is overlapped with high low speed two, comprise input shaft 1, be connected by helical tooth external tooth 2 and helical tooth internal tooth 3 between input shaft 1 with sliding assembly 4, connected by gears meshing between the outer driving gear 11 of sliding assembly 4 and the interior driving gear 10 exporting ring gear 7, the cylindrical of sliding assembly 4 is provided with low speed ratchet 5, the endoporus place of the output ring gear 7 of low speed ratchet 5 relevant position is provided with low speed ratchet 6, the other end endoporus place exporting ring gear 7 is provided with high speed ratchet 9, the cylindrical place of the sliding assembly 4 of high speed ratchet 9 relevant position is provided with high speed ratchet 8.
Described input shaft 1 is connected by helical tooth external tooth 2 and helical tooth internal tooth 3 with between sliding assembly 4, when input shaft 1 direction relative to sliding assembly 4 is rotated in place, interior driving gear 10 engages with outer driving gear 11 and engages, when input shaft 1 another direction relative to sliding assembly 4 is rotated in place, interior driving gear 10 is thrown off with outer driving gear 11 and is engaged.
When exporting ring gear 7 and running in the slow-speed of revolution, input shaft 1 synchronization also has when surmounting trend, low speed ratchet 5 will withstand the low speed ratchet 6 on sliding assembly 4, namely click produces sour jujube cooperation use, impel sliding assembly 4 relatively input shaft 1 to spin motion, until outer driving gear 11 and interior driving gear 10 all engage, now clutch completes joint action, otherwise be in the clutch of jointing state, when output ring gear 7 slows down input shaft 1 relatively, sliding assembly 4 does reverse spiral motion, thus clutch is thrown off automatically.
When exporting ring gear 7 and running at high rotating speed, input shaft 1 synchronization also has when surmounting trend, high speed ratchet 9 will withstand the high speed ratchet 8 on sliding assembly 4, namely click produces sour jujube cooperation use, impel sliding assembly 4 relatively input shaft 1 to spin motion, complete joint action, disconnecting process is as above-mentioned.
