Technical field
The utility model belongs to technical field of crane equipment, is specifically related to a kind of retarder, particularly one retarder used for electric hoist.
Background technology
Electric block is a kind of weight-lifting equipment, be arranged on driving, gauntry crane, have volume little, from heavy and light, simple to operate, the feature such as easy to use, be widely used in the place such as industrial and mining enterprises, storage harbour, domestic retarder used for electric hoist, due to its design defect, retarder accuracy of manufacture and driving efficiency are not high, and often with very large noise in operational process, because the unreasonable retarder load-carrying capacity that makes of structure is low, the operating efficiency of whole retarder is high; Therefore, provide a kind of rational in infrastructure, easy to use, load-carrying capacity is large, the high retarder used for electric hoist of operating efficiency is necessary.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and provide a kind of rational in infrastructure, easy to use, load-carrying capacity is large, the high retarder used for electric hoist of operating efficiency.
The purpose of this utility model is achieved in that a kind of retarder used for electric hoist, it comprises casing, described casing is provided with bearing A, the inner side of described bearing A is provided with axle A, described axle A is provided with gear A, described gear A is connected with gear B, the inner side of described gear B is provided with axle C, described axle C arranged outside has bearing C, the middle part of described axle C is provided with idle wheel, described axle C is also provided with gear C, described gear C is connected with gear D, the inner side of described gear D is provided with axle B, the arranged outside of described axle B has bearing B.
Described gear A, gear B, gear C are identical with the modulus of gear D.
Described gear A, gear B, gear C and gear D are straight gear.
Described bearing A, bearing B and bearing C are tapered roller bearing.
Described idle wheel is cylinder idle wheel.
The beneficial effects of the utility model: the utility model adopts axle A, axle B and axle C, axle A is input shaft, axle B is output shaft, in use, axle A can connect electrical motor, and axle B connects reel, adopts gear A, gear B, gear C and gear D, the reduction of rotating speed can be realized, make reel obtain larger torque; Axle C is provided with idle wheel, can realizes equilibrium of forces in driving system, not only make retarder operation steady, noise is little, and can obtain larger torque, and the work efficiency of retarder is uprised, and load-carrying capacity increases; The utility model has rational in infrastructure, easy to use, that load-carrying capacity is large, operating efficiency is high advantage.
