The present invention discloses a tapered braking device for 9500LBS electric winches disposes a section of gear shaft, a section of core shaft, a wedge shape support, braking plates, an elastic element, a wedge shape piece A, a wedge shape piece B, a braking clutch base and so on in a gear box of an electric winches.
When a motor works, the section of core shaft of the motor can drive the braking clutch base and the wedge shape pieces A, B to rotate, until a gap is formed between the friction faces of the wedge shape support and the wedge shape piece B and the braking plates so that the braking action stops. When the motor suddenly stops, a heavy load lifted by a tight wire rope reel provides a reverse pulling force so that the wedge shape piece B produces a reverse thrust force to push the friction faces of the braking plates, so the braking effect is achieved quickly. Based on the braking plates with the double tapered faces, the present invention can increase the braking area and the braking force and achieve safe braking. Furthermore, worn parts concentrate in the braking plates, so it only needs to replace the braking plates made of friction materials, which can simplify maintenance, reduce the costs and ensure service life of the gearbox.
Electric winches pull products by means of reeling tight cable television set rope for self-aid and buddy help in auto mishaps all through the fields. For staying away from stall of tight cable television set rope brought on by sudden energy reduce all through retracting, braking products are disposed forensuring protected operation.
The braking unit utilizes the area of middle shaft extending all through the engine shaft to generate the braking clutch bottom to rotate. inner double flanges all through the braking clutchbase simultaneously generate the wedge type product A along using the wedge type product B to rotate. At this time, the braking plate inside the wedge type product B as well as a friction tapered confront using the units box nonetheless retain a gap therebetween, so the braking unit is in anon-braking state. once the engine all of a sudden stops, the inertia using the braking clutch bottom prospects to the fact that wedge type product B moves axially even although rotating to generate the braking plate to acquire the individual tapered confront braking using the units box.
However,the braking unit has the shortcomings the fact that braking area along using the braking force made over the individual tapered confront braking is small, that will simply final result in slipping phenomena, and extra chiefly the braking plate straight functions inside the tapered confront ofthe units box, that will simply make the tapered confront to turn into placing on directly, to make certain the fact that tapered confront get rid of braking efficacy.
Then the units box should be replaced, which prospects to challenging upkeep and large substitute reselling price of parts.
An item using the present creation will be to provide a tapered braking unit for electrical winch which has the benefits of bigger braking area, good braking effects, reduce substitute reselling price of components and staying away from placing on a units box directly.
To acquire the above-mentioned object, a tapered braking unit for electrical winch in accordance using the present creation is disclosed.
