Electric winch braking mechanism, as shown in Fig. 1 ~ Fig. 3, relate to one dilatory object under electric winch carries out there is angle case, or when there is the emergency situation that cable wire ruptures suddenly, drag can be carried out in time to promote the brake gear of electric winch use safety, the two ends that its structure mainly comprises the driving wheel 3 be set in parallel in electric winch, brake tooth axle 6 and worm screw 13, three rooted tooth axle are equipped with bearing and rotate supporting.
Described driving wheel 3 one end is connected with the motor 1 be fixedly mounted on outside electric winch housing, therefore for transmitting the power that motor 1 inputs; Described worm screw 13 is that this worm screw 13 one end is provided with the transmission gear 11 be in transmission connection, and this transmission gear is engaged on again on brake tooth axle 6, therefore the rotational of brake tooth axle drives worm screw 13 to make synchronous axial system for driving cylinder 12 to reel the output block of cable wire.
According to being from top to bottom provided with the locating bush 7, the ratchet cover plate 5, friction pair 4 and the rotating disc 2 that are set with and install shown in Fig. 1 successively on described brake tooth axle 6, also be provided with the spur gear 9 of gear Inner spline 91 movable set, this spur gear is engaged on driving wheel 3, and drives rotation by driving wheel.
Wherein, locating bush 7 is fixedly mounted on brake tooth axle 6 by locating dowel pin 14, and for the installation site of positioning ratchet wheel dish 5 on brake tooth axle 6.
The ratchet cover plate 5 movable set is on brake tooth axle 6, flexible rotating can be made on brake tooth axle, that the outside of the ratchet cover plate 5 is provided with supporting installation, that turning effort is provided by torsion spring 20 ratchet 19, this ratchet carries out engaging with the unidirectional ratchet on the ratchet cover plate 5 outer circumference surface and holds out against or depart from engagement, thus forms corresponding action and coordinate; The lower surface of the adjacent friction pair 4 of the ratchet cover plate 5 is provided with mounting groove 51, in being fixedly inlaid in by the brake facing 10 of a cyclic structure by many pins 15 in this mounting groove.
Friction pair 4 is also movable set on brake tooth axle 6, is set to the matching relationship of the conical surface and taper hole between the peripheral and brake facing 10 in the upper surface of this friction pair 4 adjacent ratchet dish 5, and namely friction pair 4 is close to brake facing 10 and just can be realized drag; The brake spring 8 of mutual pushing tow is also provided with between described friction pair 4 and the ratchet cover plate 5, in the two ends spring groove 16 that pushing installation is preset on the ratchet cover plate 5 with the adjacent face of friction pair 4 respectively of this brake spring, under normality, by the pushing tow of brake spring 8, the ratchet cover plate 5 and friction pair 4 are in mutually away from state; Described friction pair 4 lower surface is provided with the tooth post 41 that concentric extends, and this tooth post is engaged in the gear Inner spline 91 of spur gear 9, therefore the rotation of spur gear 9 can drive tooth post 41, friction pair 1 makes synchronous axial system.
Described rotating disc 2 is fixedly mounted on brake tooth axle 6 by locating dowel pin 14, the upper surface of the adjacent friction pair 4 of this rotating disc 2 is stretched in the gear Inner spline 91 of spur gear 9, but there is no meshing relation with this gear Inner spline 91, namely the rotation of spur gear 9 can not be rotated by driven rotary dish 2; Described rotating disc 2 upper surface and tooth post 41 lower surface are respectively equipped with surface of revolution 17, this surface of revolution refers to the rotation slope with lowest part and highest point 18, rotating disc 2 upper surface and tooth post 41 lower surface of the present embodiment are equipped with two surface of revolutions 17, and two surface of revolutions 17 join end to end in the circle shape design of 360 degree; Simultaneously, rotation slope on rotating disc 2 and tooth post 41 is the installation relation of opposite spin, when surface of revolution 17 between rotating disc 2 and tooth post 41 drives friction pair 4 to do positive and negative rotation by spur gear 9, just can form action to coordinate, and friction pair 4 rotating disc 2 relative to rotating disc 2 synchronous axial system or friction pair 4 is moved axially and overcomes brake spring 8 and hold out against on brake facing 10.
Mode of operation of the present utility model is mainly divided into normal rotation state and drag state.
Cylinder 12 can be driven when normal rotation state refers to that electric winch starts to reel cable wire and normally drawing, promote or dilatory object, its specific works process is as Fig. 4, shown in Fig. 5, motor 1 input power drives driving wheel 3 to rotate, and then drive the spur gear 9 engaged with driving wheel to rotate counterclockwise, now friction pair 4 is also driven conter clockwise synchronous axial system, owing to being provided with the surface of revolution 17 that reversing sense is installed between friction pair 4 and rotating disc 2, the highest point 18 of these two surface of revolutions rotate counterclockwise under state by the pushing tow of brake spring 8 be mutually near, therefore friction pair 4 also can make synchronous axial system by driven rotary dish 2, and the power that friction pair 4 inputs just can pass through rotating disc 2 successively through brake tooth axle 6, transmission gear 11, worm screw 13 and drive cylinder 12 rotate forward winding cable wire, pushing tow mutual between friction pair 4 and brake facing 10 can depart from by the brake spring 8 under normal rotation state, therefore the rotation of friction pair 4 can not be subject to the restriction of brake facing 10, and ratchet 19 and the ratchet cover plate 5 are in disengaging engagement as shown in Figure 5.
Drag state refers to that electric winch is in order to avoid object dilatory in angled situation, or the safety control occurring the emergency situation that cable wire ruptures suddenly and make, its specific works process is as Fig. 6, shown in Fig. 7, when the cable wire on cylinder 12 is driven decline by weight, cylinder 12 reverses and drives worm screw 13 and the formation of brake tooth axle 6 to rotate clockwise, owing to being provided with the surface of revolution 17 that reversing sense is installed between friction pair 4 and rotating disc 2, the highest point 18 of these two surface of revolutions is mutually throw off rotating clockwise under state, and mutually can form climb mode between surface of revolution 17, and then overcome the thrust of brake spring 8 and pushing tow friction pair 4 relatively rotating disc 2 do axially to move up, thus cause friction pair 4 to be close on brake facing 10 being subject to limit rotation, and ratchet 19 and the ratchet cover plate 5 are in as shown in Figure 7 hold out against engagement and be subject to limit rotation, therefore finally serve the object of drag.
