Embodiment
The specific embodiment of the present invention is described in detail below in conjunction with preferred embodiment.Refer to accompanying drawing,
Refer to Fig. 1, the invention provides a kind of roller shutter machine of solar greenhouse with pressure differential friction catch mechanism, original shutter is twin-stage small Tooth Number Difference Planetary Transmission structure, its one-level internal gear 12 is fixed in support 2, one-level external gear 13 and one-level internal gear 12 are nibbled merga pass bearing 14 and are arranged on one-level eccentric shaft 16, and inside its one-level external gear, axle head is provided with the float rectangular channel 21 of chute device 11 side of a word slide block and the one-level cross be socketed on one-level eccentric shaft 16 and kisses and grafting; One-level eccentric shaft 16-hold is arranged on support end cap 17 by bearing 15, and its eccentric shaft other end is fixed on secondary eccentric shaft 3 right-hand member by bearing 9; Be fixed between secondary internal gear 6 in support 2 and one-level internal gear 12 and be equipped with diaphragm housing ring 10, the end face of secondary eccentric shaft 3-end there is the float rectangular channel 21 of chute 11 opposite side of a word slide block and one-level cross kiss and grafting, and be arranged on diaphragm housing ring 10 by bearing 8, its secondary eccentric shaft other end and output shaft 1 keyed jointing, secondary external gear 5 and secondary internal gear 6 are nibbled merga pass bearing 7 and are arranged on secondary eccentric shaft 3, and inside its secondary external tooth powder, axle head is provided with the float rectangular channel of chute device 4 opposite side of a word slide block and the secondary be socketed on eccentric shaft 3 and coincide grafting.The chute device that floats makes the axial distance of twin-stage eccentric shaft greatly shorten, then need not strengthen radial dimension, can meet the requirement increasing output torque; Keep the certain offset of eccentric shaft; Adopt the low module planetary gear of special tip relief can ensure that volume is little, the requirement that output torque is large can be ensured again; In the small Tooth Number Difference Planetary Transmission of traditional design, only have 1 pair of tooth engagement to become 5-6 engage tooth.In order to avoid shutter reversion, cantilevered major axis is caused to drive canopy curtain to glide.The arrestment mechanism of shutter arranges differential pressure friction catch mechanism between the one-level little gear difference planetary driving mechanism and secondary little gear difference planetary driving mechanism of original structure.Refer to accompanying drawing 2-4, differential pressure friction catch mechanism mainly arranges play the annular stop round platform 22 of braking action in a float centre, side of chute device of one-level cross, described annular stop round platform arranges at the float inner surface in the relative secondary little gear difference planetary driving mechanism direction of chute device of one-level cross, and described annular stop round platform floats with bearing 7 inner peripheral surface be fixed on secondary eccentric shaft and touches.Bearing inner race diameter matches on described annular stop round platform diameter and secondary eccentric shaft.Float chute and annular stop round platform opposed surface of described one-level cross is provided with elastic pressuring clamping device.The end face of elastic pressuring clamping device and one-level eccentric shaft compresses.Described elastic pressuring clamping device comprises steel ball 18 and spring 19, described steel ball and spring are placed in one-level cross successively and float the circular hole 20 of detent surface, the part that described steel ball is placed in circular hole is more than or equal to 2/3 of its diameter, keeps the end face of steel ball and one-level eccentric shaft to compress.The quantity of described steel ball and spring is 2-4 group.The present embodiment selects four groups, and balance can be kept to power.
Operation principle: the rubbing surface synchronous with power shaft and relative differential side, fill a pressure rubbing device, namely, a float centre, side of chute device of one-level cross arranges and plays the annular stop round platform 22 of braking action, described annular stop round platform arranges at the float inner surface in the relative secondary little gear difference planetary driving mechanism direction of chute device of one-level cross, and described annular stop round platform floats with bearing 7 inner peripheral surface be fixed on secondary eccentric shaft and touches.To realize synchronous simultaneously therewith, and realize pressure differential friction catch.When power shaft starts, load is very little, and rubbing between differential with startup speedup produces oil film, plays slip effect, do not produce input resistance during axle full gear to be entered.When power shaft deceleration stops, pressure apparatus produces pressing, and phase the other side wants to rotate and will twist input side by the resistance of reverse 1 thousand to two thousand times of transmission velocity ratio.Realizing when braking is the very heavy lever principle dialling four liang, is the lever principle that art is good for strength during input.Slip oil drag during high speed, its wearing and tearing reason and sliding bearing belong to together.Because frictional resistance is identical with sliding bearing, therefore do not affect input torque, its component life is very long.During conventional startup, need one to three times of starting torque instantaneously, now the slow moment of torsion of its rotating speed overcomes greatly pressure frictional resistance, produces inertia to when running up, and oil film flow velocity is full simultaneously closes friction pressure elimination, realizes sliding friction, therefore does not affect input torque.Device actual measurement input torque 1(kilogram. rice) time, output torque 1200 kilograms. rice.When input stopping turns, 1300 Kg load brakings, fixing.
The above is only preferred embodiment of the present invention, not does any pro forma restriction to structure of the present invention.Every above embodiment is done according to technical spirit of the present invention any simple modification, equivalent variations and modification, all still belong in the scope of technical scheme of the present invention.
