Description
technical field:
The present invention relates to mechanical transmission fields, the mechanism that specifically in a kind of synchronous automatic clutch, click radial direction is thrown off.
background technique:
At present, synchronous automatic clutch has been widely used in military products, chemical industry, metallurgy, the every field such as energy-conservation, and the working principle of synchronous automatic clutch automatically realizes engaging, throwing off according to the rotating speed of master and slave moving axis.Clutch is in engaging process, and when click is axially thrown off rapidly, clutch driving gear (interior external tooth) must circumferentially fast movement, and tooth working surface is contacted by jail.Because flank has comparatively wide arc gap, and it is large to engage differential angular acceleration, and clutch can produce larger shock in engagement process.The shock caused during self-synchronizing clutch synchromesh, be a very important problem, it is related to the working life of clutch and affects power plant performance of handoffs, so this is the problem that clutch designs must solve.
summary of the invention:
Clashing into ensure to reduce in engagement process, the invention provides a kind of synchronous automatic clutch with the radial trip gear of click and replacing conventional synchronous automatic clutch.
Technological scheme of the present invention is: the mechanism that in synchronous automatic clutch, click radial direction is thrown off, comprise output terminal flange, output terminal flange and output member are bolted, input end flange is bolted with input ring gear, input ring gear is by connecting sleeve internal tooth, connecting sleeve external tooth is connected with sliding component, sliding component is equipped with driving gear internal tooth, output member is equipped with driving gear external tooth, middle screw rotating part and output member are bolted, ratchet is by slippage tooth internal tooth, slippage tooth external tooth is connected with middle screw rotating part, hold ring and end ring is bolted with sliding component respectively, ratchet is arranged on to be held in ring, baffle ring and middle screw rotating part are bolted.
The oblique angle α of driving gear external tooth, driving gear internal tooth, the relation of the oblique angle β of slippage tooth external tooth, slippage tooth internal tooth, α and β is 0 ° of < α < β < 30 °.
Described ratchet is arranged on to be held in ring, and ratchet is arranged on to be held between ring and end ring.
Sliding component moves axially in the process of distance d18, the radial throw-off distances T of ratchet and ratchet, and slippage tooth internal tooth is spinned the distance T1 of motion radial direction, and driving gear internal tooth is spinned the distance T2 of motion radial direction, distance T=T1-T2.
The present invention has following beneficial effect: change radial novel ratchet ratchet of throwing off into by the click of conventional axial being thrown off, and eliminates shock during clutch engagement, improves Security and the maintenance of clutch use, reduces maintenance cost.

embodiment:
Below in conjunction with accompanying drawing, the invention will be further described:
Shown in Fig. 1 composition graphs 2 ~ Fig. 3, the mechanism that in synchronous automatic clutch, click radial direction is thrown off, comprise output terminal flange 1, output terminal flange 1 and output member 2 are bolted, input end flange 10 is bolted with input ring gear 11, input ring gear 11 is by connecting sleeve internal tooth 16, connecting sleeve external tooth 17 is connected with sliding component 5, sliding component 5 is equipped with driving gear internal tooth 4, output member 2 is equipped with driving gear external tooth 3, middle screw rotating part 15 and output member 2 are bolted, ratchet 7 is by slippage tooth internal tooth 14, slippage tooth external tooth 13 is connected with middle screw rotating part 15, hold ring 9 to be bolted with sliding component 5 respectively with end ring 6, ratchet 8 is arranged on to be held in ring 9, baffle ring 12 and middle screw rotating part 15 are bolted.
The oblique angle α 19 of driving gear external tooth 3, driving gear internal tooth 4, the oblique angle β 20 of slippage tooth external tooth 13, slippage tooth internal tooth 14, α 19 is 0 ° of < α 19 < β 20 < 30 ° with the relation of β 20, and ratchet and pawl can be made to produce radial clearance.
Described ratchet 8 is arranged on to be held in ring 9, and ratchet 7 is arranged on to be held between ring 9 and end ring 6.
Sliding component 5 moves axially in the process of distance d18, ratchet 7 and the radial throw-off distances T22 of ratchet 8, slippage tooth internal tooth 14 is spinned the distance T123 of motion radial direction, driving gear internal tooth is spinned the distance T221 of motion radial direction, distance T22=T123-T221, can make ratchet and pawl produce radial clearance.
When input end flange 10 with output terminal flange 1 synchronization and have surmount trend time, ratchet 7 will withstand the ratchet 8 held on ring 9, namely click produces sour jujube cooperation use, input ring gear 11 is for the helical movement relatively along slippage tooth external tooth 13 to impel ratchet 7, namely the relative output member 2 of ratchet 7 axially moves, simultaneously, hold ring 9, end ring 6, ratchet 8 axially moves with ratchet 7 together with sliding component 5, make driving gear outer 3, driving gear internal tooth 4 enters engagement, and flank is close to, clutch engages, otherwise be in the clutch of jointing state, when output terminal flange 1 slows down input end flange 10 relatively, active force between output terminal flange 1 and sliding component 5 does reverse spiral motion by making sliding component 5, thus clutch is thrown off automatically.
Ratchet 7 ratchet 8 is not axially thrown off, ratchet 7 carries out spiral motion along the oblique angle α 19 of driving gear, ratchet 8 carries out spiral motion along the oblique angle β 20 of slippage tooth, because oblique angle is different, ratchet 7 produces gap with ratchet 8 radial disengagement, the effect in gap is that sour jujube cooperation use no longer occurs ratchet and pawl, thus makes it not bear load.
