Feature of the present invention and advantage will be elaborated by reference to the accompanying drawings by embodiment.
[description of drawings]
Fig. 1 is the structural representation of band buffering no touch ratchet holdback running state of the present invention;
Fig. 2 is the structural representation of band buffering no touch ratchet holdback non-return state of the present invention.
[specific embodiment]
As shown in Figure 1, 2, band buffering no touch ratchet holdback is comprised of fixed body, gyro-rotor, buffer body three parts.Core wheel 1, bearing pin 2, ratchet 5, locating dowel pin 8, torsion spring 9, spring pin 10 form one group of gyro-rotor; Gear ring 4, check arm 11 form a fixed body; Slide block 7, energy absorbing resin rod 6 form one group of check buffer body.
Fixed body: be comprised of check arm 11 and the gear ring 4 that is fixedly mounted on the check arm 11, gear ring 4 has some buffer body mounting grooves for being provided with the annular arrangement of revolution cavity on the madial wall of gear ring 4, and the both sides of buffer body mounting groove all are outward extended with guide groove.Also be provided with oil nipple 3 on the gear ring 4.
Gyro-rotor: gyro-rotor is installed in the revolution cavity, gyro-rotor comprises core wheel 1, ratchet 5, torsion spring 9, locating dowel pin 8, core wheel 1 is rotatable under external force, be distributed with 4 ratchets that can swing under external force 5 along even circumferential on the core wheel 1, one end of ratchet 5 is large end, the other end is small end, the weight ratio small end of large end is heavy, core wheel 1 is provided with torsion spring 9 and the locating dowel pin 8 corresponding with ratchet 5, one end of torsion spring 9 props up core wheel 1, the other end props up the small end of ratchet 5, and locating dowel pin 8 is fixedly mounted on the core wheel 1 and is positioned at the inboard of the small end of ratchet 5; The middle part of ratchet 5 adopts bearing pin 2 to be installed on the core wheel 1, and torsion spring 9 adopts spring pin 10 to be installed on the core wheel 1.
Check buffer body: formed by slide block 7 and buffering resin rodlet 6, slide block 7 is installed in the buffer body mounting groove of gear ring 4, one side of slide block 7 has skewed slot, opposite side is provided with elastically-deformable energy absorbing resin rod 6 can occur, the shape of skewed slot is corresponding with the shape of ratchet 5 small ends, and the small end of ratchet 5 can snap in the skewed slot when core is taken turns 1 backwards rotation.The both sides of slide block 7 are extended with the guiding rib that cooperates with guide groove.
State during operation is consulted Fig. 1: gyro-rotor is during to service direction (among the figure for anticlockwise direction) running, because ratchet 5 one sides lay particular stress on, under centrifugal action, lay particular stress on side (large end) outwards, partially light side (small end) inwardly overcomes the action of torsion spring 9 resistances, until rotating speed 〉=during 200r/min, small end moves to the limited pin 8 in locating dowel pin 8 places to be stopped; In this operational process, since gapped between gyro-rotor and fixed body, the buffer body, so gyro-rotor moves under the no touch state.
State during check is consulted Fig. 2: gyro-rotor from turn round → stop → the whole process that reversing because centnifugal force constantly reduces, ratchet 5 ejects under torsion spring 9 effects, enters in the skewed slot space of slide block 7, until fit like a glove; After ratchet 5 was identical with the skewed slot of slide block 7, under the stalling torque effect, elastic deformations can occur in energy absorbing resin rod 6, until stop.The effect of energy absorbing resin rod 6: buffering reverses impulsive force, eliminate calibration deviation in the manufacturing process so that four ratchets 5 are stressed be tending towards average, reverse power and eliminate after so that slide block 7 can reset.
Core wheel 1, bearing pin 2, ratchet 5, torsion spring 9, gear ring 4, slide block 7 all can adopt alloy material, through bakingout process, guarantee product design.Band buffering no touch ratchet holdback tennis partner dynamic clutch can also use as overriding clutch simultaneously.Compare with hoist driving device commonly used and can reduce a holdback (gig commonly used drives two holdbacks, and is used for check, another and is used for the auxiliary machine of conducting electricity and makes overriding clutch and use), reduced expense, the easier approval that obtains the user.This product is on probation through inside to have good effect, has adapted to the development tendency of cement industry, selects and supporting space for the user provides.
Above-described embodiment is to explanation of the present invention, is not limitation of the invention, any scheme after the simple transformation of the present invention is all belonged to protection scope of the present invention.
