There is the synchronous automatic clutch of high pulling torque of midsequent structure
technical field:
The utility model relates to mechanical transmission fields, specifically a kind of synchronous automatic clutch of high pulling torque with midsequent structure.
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.From when driving shaft rotating speed is higher than output speed, click generation sour jujube cooperation use, sliding component moves axially, and the driving gear of clutch is engaged.Otherwise, throw-out-of clutch.Steam turbine cogeneration field is the technology of a comprehensive energy utilization, and the synchronous automatic clutch applied in cogeneration field is very large due to the moment of torsion transmitted, and causes the size of clutch large, quality weight.In engagement/disengagement process, the impact that click bears is large, and the safety coefficient of clutch reduces.Therefore, the design problem of the synchronous automatic clutch of high pulling torque must be solved.
model utility content:
In order to improve the technical performance of the synchronous automatic clutch of high pulling torque, the synchronous automatic clutch that the utility model provides a kind of midsequent structure replaces conventional synchronous automatic clutch, clutch after improvement improves clutch anti-impact force, substantially reduces the external dimension of clutch.
The technical solution of the utility model is: the synchronous automatic clutch of high pulling torque with midsequent structure, comprise output ring gear, output ring gear and relaying ring gear are bolted, main sliding assembly is by driving gear external tooth, driving gear internal tooth is connected with output ring gear, main sliding assembly is by main slippage tooth external tooth, main slippage tooth internal tooth connects input ring gear, spiral ring gear and main sliding assembly are bolted, spiral ring gear is by secondary spiral slippage tooth external tooth, secondary spiral slippage tooth internal tooth connects relaying sliding component, relaying sliding component installs ratchet, relaying ring gear installs ratchet, relaying sliding component is by relaying tooth external tooth, relaying tooth internal tooth connects relaying ring gear.
The utility model has following beneficial effect: new structure (comprises click at the synchronous automatic clutch of routine, principal screw slippage tooth, main sliding assembly and driving gear four parts) basis on, add a set of secondary spiral slippage tooth, relaying tooth and relaying sliding component, the joint action of clutch decomposes two steps by a step to be completed, when click sour jujube is closed, secondary spiral slippage tooth promotes the little relaying sliding component axial slip of inertia, after click is thrown off, a pair relaying indented joint, replace click, principal screw slippage tooth promotes the large main sliding assembly axial slip of inertia, so just make click from large impact, make the engaging process of clutch safer, by the synchronous automatic clutch of synchronous automatic clutch midsequent by routine, improve clutch anti-impact force, substantially reduce the external dimension of clutch.
accompanying drawing illustrates:
Fig. 1 is the utility model structural representation;
Fig. 2 ~ Fig. 4 is working procedure schematic diagram of the present utility model.
In figure, 1-exports ring gear, 2-driving gear external tooth, 3-driving gear internal tooth, the main sliding assembly of 4-, 5-main slippage tooth external tooth, 6-main slippage tooth internal tooth, 7-inputs ring gear, 8-relaying tooth external tooth, 9-relaying sliding component, 10-relaying tooth internal tooth, 11-ratchet, 12-secondary spiral slippage tooth internal tooth, 13-secondary spiral slippage tooth external tooth, 14-spiral ring gear, 15-ratchet, 16-relaying ring gear.
embodiment:
Conventional synchronous automatic clutch comprises click, principal screw slippage tooth, main sliding assembly and driving gear four parts, the utility model is on the basis of conventional synchronous automatic clutch, add a set of secondary spiral slippage tooth, relaying tooth and relaying sliding component, the joint action of clutch decomposes two steps by a step to be completed.When click sour jujube is closed, secondary spiral slippage tooth promotes the little relaying sliding component axial slip of inertia, after click is thrown off, a pair relaying indented joint, replace click, principal screw slippage tooth promotes the large main sliding assembly axial slip of inertia, so just makes click from large impact, makes the engaging process of clutch safer
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Shown in Fig. 1 composition graphs 2 ~ Fig. 4, there is the synchronous automatic clutch of high pulling torque of midsequent structure, comprise and export ring gear 1, export ring gear 1 to be bolted with relaying ring gear 16, main sliding assembly 4 is by driving gear external tooth 2, driving gear internal tooth 3 is connected with output ring gear 1, main sliding assembly 4 is by main slippage tooth external tooth 5, main slippage tooth internal tooth 6 connects input ring gear 7, spiral ring gear 14 and main sliding assembly 4 are bolted, spiral ring gear 14 is by secondary spiral slippage tooth external tooth 13, secondary spiral slippage tooth internal tooth 12 connects relaying sliding component 9, relaying sliding component 9 is installed ratchet 11, relaying ring gear 16 is installed ratchet 15, relaying sliding component 9 is by relaying tooth external tooth 8, relaying tooth internal tooth 10 connects relaying ring gear 16.
When input ring gear 7 with export ring gear 1 synchronization and have surmount trend time, the ratchet 11 that ratchet 15 will withstand on relaying sliding component 9, namely click produces sour jujube cooperation use, relaying sliding component 9 opposed helical ring gear 14 is impelled to spin motion, until relaying tooth external tooth 8 and relaying tooth internal tooth 10 are all after engagement, main sliding assembly 4, spiral ring gear 14 is spinned motion together with relaying sliding component 9, until driving gear external tooth 2 and driving gear internal tooth 3 all engage, now clutch completes joint action, otherwise be in the clutch of jointing state, when inputting ring gear 7 relative output ring gear 1 and slowing down, main sliding assembly 4, spiral ring gear 14 does reverse spiral motion together with relaying sliding component 9, thus clutch is thrown off automatically.
