The utility model has compact structure and convenient disassembly and maintenance, and is particularly applicable to the main transmission of heavy machinery with a large torque, a large reduction ratio and a low rotating-speed output, such as the tilting device of a modern steel converter, the transmission devices of an oversize windlass and a sintering machine and so on.

Description

Nibble complete outstanding gentle transmission device more
The utility model belongs to the mechanical transmissioning technology field, a kind of flexible gearing that is specially adapted to heavy duty equipment.
Now, to acting on the main transmission of big torque, big retarding ratio and slow-speed of revolution output jumbo, trend uses the common name multiple spot to mesh flexible transmission (being called for short many gentle transmissions) device, such as large-scale winch, excavator, disintegrator, grinding machine, rotary kiln, stirrer, sintering machine, hot-metal car, metal mixing furnace, steelmaking converter, sugar making machine and portal crane etc.This class is the general character and the characteristics of gentle transmission device how: utilization multiple spot outer gearing power dividing is to improve bearing capacity and to reduce overall sizes; The hollow shaft suit is suspended on distortion and the beat to adapt to main shaft on the machine spindle; And sinking support is with balance and alleviation impact dynamic load between the basis.Its fundamental composition all contains one and is suspended on the final stage speed reducer that has the multiple spot outer gearing on the machine spindle, several elementary (or first, middle rank) speed reduceres that connect with the final stage speed reducer, prime mover driven system, and sinking support mechanism.
Yet how gentle this class transmission device still come with some shortcomings, and be example with the modern steelmaking converter tiling arrangement of tool typical structure form: 1) lost motion of final stage speed reducer multiple spot outer gearing transmission is bigger, is difficult to satisfy all carry requirement; 2) the final stage speed reducer is only shared reduction speed ratio 6.5~8, all the other than big retarding than (converter about 100, sintering machine is often greater than 200) must bear by the elementary speed reducer that is no less than three grades of cylindrical gearss decelerations, often need join than slow-speed of revolution prime mover driven, cause elementary speed reducer and drive system bigger than normal, overweight thus, to further raising bearing capacity, reduce overall sizes and limited to adapt to the compact arrangement needs; 3) fixed between elementary and final stage speed reducer with flange, import and be output as the non-statically determinate structure of coaxial three-point support, make carrying be in unfavoured state, final stage speed reducer backlash can not be adjusted, split dismounting difficulty; 4) because of being fixed inflexibility supporting between elementary and final stage speed reducer, so be unfavorable for relaxing the impact dynamic load between the two, when adopting the hardened face gear engagement, it is on the low side to show anti-overload ability especially.
The purpose of this utility model is to propose the how gentle transmission device that a kind of structure is more perfect, performance has more advantage.It not only the final stage speed reducer take multiple spot outer gearing shunting transmission, and each elementary speed reducer is adopted engagement shunting transmission (national inventing patent 85106692.5) in three-ring type multiple spot, make the backlash of final stage speed reducer adjustable simultaneously; Not only final stage speed reducer suit on machine spindle hangs, and each elementary speed reducer suit on each input shaft of final stage speed reducer hangs; Not only take sinking support between final stage speed reducer and basis, and also take sinking support between each elementary speed reducer and final stage speed reducer.What constituted has outer gearing in the multiple spot, integral and a full sinking support transmission device, is called for short and nibbles the complete outstanding transmission device that softens more.
The purpose of this utility model realizes by following proposal.Should nibble complete outstanding gentle transmission device more, form by final stage speed reducer, sinking support mechanism, the elementary speed reducer of three-ring type and prime mover single driving system etc.The final stage speed reducer is multiple spot outer gearing shunting transmission, its input small gear is generally 2~6, the input shaft end of each small gear is overhung at outside the case, hang for each elementary speed reducer suit, install eccentric bushing between the block bearing of each small gear and casing bearing hole additional in order to adjust backlash, the gearwheel output shaft is made hollow hole, just hangs with the machine spindle suit.The sinking support mechanism of supporting final stage speed reducer can be made into self balancing torsion bar or gravitational equilibrium two-fold form of springs, or the two share.The elementary speed reducer of three-ring type has that three ring drive technology reduction speed ratio are big, carrying is strong and structural advantage, can synthesize dynamo-electric integrated machine with drive systems such as prime mover, detection device, breaks, its output shaft is also made hollow hole, just the input shaft extension suit with the final stage speed reducer hangs, have 1~4 pin ear on the casing, be connected with the key seat on being fixed on the final stage speed reducer, constitute the mobile flexible supporting.Drive systems such as prime mover, detection device, break also can with elementary speed reducer packing, be fixed on voluntarily on the support on the final stage speed reducer, at this moment dress allows the coupling of big displacement beat to be connected between the input shaft extension of drive system and elementary speed reducer.
Effect of the present utility model: 1) compact structure, to be convenient to be provided with, it is about 24.7% that radial width reduces, and axial length reduces about 11%; 2) the device loss of weight is about 13.2%, and cost saves about 11.5%; 3) operational safety improves with the dynamic load performance that withstands shocks, and overloading ratio allowable improves about 35%; 4) easy dismounting and maintenance.
Below in conjunction with accompanying drawing two embodiments of the present utility model are further described.
