Abstract
The invention discloses a flexible connection input module for a gear speed reducer. The input module comprises a module input end, a transmission structure and a module output end, wherein the transmission structure comprises an inner sleeve and an outer sleeve; four inner clapboards extending to the outer sleeve are uniformly distributed on an outer wall of the inner sleeve along a sleeve wall; four outer clapboards extending to the inner sleeve are uniformly distributed on the inner side of the outer sleeve along a sleeve wall; the inner clapboards and the outer clapboards are uniformly distributed along radial directions of the inner and outer sleeves in a staggered mode; an annular space between the inner sleeve and the outer sleeve is equally divided into a plurality of accommodating spaces; and an elastic object is accommodated in each accommodating space. The traditional gear engagement drive mode is abandoned, and a drive mode of extruding elastic objects through input sleeve inner clapboards so as to push output sleeve outer clapboards is adopted. When a motor is started, stopped and subjected to emergency brake, the elastic object is compressed and deformed, and abrupt change of torque is retarded; therefore, abnormal damage of an inner member of the speed reducer is effectively reduced.
Description
Technical field
The present invention relates to a kind of deceleration of building hoist special use, the special mechanical equipment of transmission, be specifically related to the improvement of the load module of retarding device.
Background technique
At present, building hoist uses worm and gear class speed reducer more, and the efficient of worm-gear speed reducer is subjected to the influence of its kind of drive, and transmission efficiency is low; Worm-gear speed reducer is subjected to the material difference of its worm screw, worm gear, and worm screw is the cutting worm gear constantly, and it is very serious to wear and tear, and working life is short; Worm-gear speed reducer is subjected to its structural limitations to have the leakage of oil problem not solve, and needs the later stage constantly to refuel, and later maintenance extremely bothers.
For example publication number is that the Chinese utility model patent of 201843941U discloses a kind of construction lifter reducer, comprise a pair of intermeshing worm gear, worm screw, this worm gear, worm screw are arranged in the reduction case, worm gear mainly is made up of worm-wheel shaft, worm-wheel hub, worm rim, be provided with key and keyway between worm-wheel shaft and the worm-wheel hub, worm-wheel shaft drives worm-wheel hub by the key kind of drive, and worm-wheel hub is by circumferentially evenly distribution bolt and worm rim interfix; Adopt toroidal surface envelope hollow flank worm pair; The end of worm screw is fixed a flange that is used to connect motor, though this model utility is in the bearing capacity, the transmission efficiency that improve building hoist, and guarantee running steadily, compact structure and low noise have some improvement, but because its worm and gear class speed reducer is worm and gear class speed reducer all the time, inefficiency, serious wear, working life are short, and problems such as later maintenance trouble still exist, and do not solve.
