Abstract
The invention relates to an extra-large-power speed reducer for a roller press. The speed reducer comprises a box, an input shaft and an output shaft. The input shaft and the output shaft are arranged at two ends of the box through bearings in a penetrating mode respectively. More than one stage of parallel shaft gear speed reduction mechanism and more than one stage of planet gear speed reduction mechanism are arranged in the box. The input shaft is in transmission connection with the output shaft through the more than one stage of parallel shaft gear speed reduction mechanism and the more than one stage of planet gear speed reduction mechanism successively, or the input shaft is movably connected with the output shaft through the more than one stage of planet gear speed reduction mechanism and the more than one stage of parallel shaft gear speed reduction mechanism successively. The input shaft and the output shaft are arranged in an eccentric mode. According to the speed reducer, axes of input and output are different, the motor assembly is facilitated, the speed ratio is increased, and output torque of the speed reducer is improved. The speed reducer is accordant with speed reduction requirements of the extra-large-power roller press, large in bearing capacity and high in transmission capacity.
Description
?
Technical field
The present invention relates to the main transmission on a kind of roll squeezer, be specifically related to a kind of superpower roller press deceleration device that is applicable to power 〉=1800KW.
Background technique
Along with national economy is fast-developing, adopt the roll squeezer new technology to be known together at cement industry, as the supporting speed reducer of roll squeezer, must possess larger bearing capacity requirement, common reducing gear power can't satisfy its large load bearing requirements, relatively common reducing gear, the power of reducing gear improve must cause that overall volume is large, Heavy Weight, mobile, inconvenience is installed.
Summary of the invention
The object of the invention is to overcome above-mentioned the deficiencies in the prior art, provide a kind of compact structure, volume little, lightweight, and the larger superpower roller press deceleration device of bearing capacity.
The technical solution used in the present invention is: a kind of superpower roller press deceleration device, comprise casing, input shaft and output shaft, input shaft and output shaft are connected to respectively the two ends of casing through bearing, it is characterized in that: be provided with the above parallel-axes gears reducing gear of one-level and the above planetary gear reducing mechanism of one-level in the described casing, input shaft is successively through the above parallel-axes gears reducing gear of one-level, the above planetary gear reducing mechanism of the one-level output shaft that is in transmission connection, or input shaft is successively through the above planetary gear reducing mechanism of one-level, one-level is to upload parallel-axes gears reducing gear be dynamically connected output shaft, input shaft and output shaft eccentric setting.
Further, described parallel-axes gears reducing gear comprises input gear and input coupling shaft, and the input gear interference is socketed on the input coupling shaft, the gear on the input gear engagement input shaft, input coupling shaft engagement driving planetary gear reducing mechanism.
Further, described planetary gear mechanism comprises ring gear, planet carrier, planet wheel and sun gear, parallel-axes gears reducing gear engagement driving sun gear, be engaged with a plurality of planet wheels that are arranged on the planet carrier on the sun gear, planet carrier is engaged in the ring gear, and planet carrier connects the sun gear of next stage planetary gear mechanism or connects output shaft or stretch out the casing end face.
Further, the end face of the planet carrier of described planetary gear mechanism is arranged in the casing through wear-resistant pad is spacing.
Further, the planet carrier of described planetary gear mechanism is through expiring roller bearing in casing.
Further, described planet carrier or output shaft are supported on the casing and pass casing through bearing, and planet carrier or output shaft fill through the output terminal cap seal.
Again further, described output end cap and planet carrier, or tight cover has the quenching wear-resistant sleeve between output end cap and the output shaft.
Adopt above technological scheme, the invention has the beneficial effects as follows: input adopts different axle center to arrange from output, be convenient to the motor assembling, power 〉=1800KW roller press deceleration device and motor be symmetrical the installation in pairs, direct current generator profile and weight ratio speed reducer are much bigger, adopt the decentraction setting, prevented the motor interference; Adopt in addition the decentraction setting, increased speed ratio, improved the output torque of speed reducer; Planetary gear mechanism planet carrier deadweight is very large, by adding the wear-resistant pad of its inclination of setting up defences, avoid planet carrier that sun gear is produced great impact and cause collapse tooth, improve the stable performance of device and Safety performance; Because planetary gear mechanism planet carrier output torque is normally all greater than 900KN*m, produce larger radial force, by two full roller bearings it is supported in the casing, can guarantee that planet carrier bears higher radial force, while and profile are little, have reached raising bearing capacity and weight reduction purpose; Directly planetary gear mechanism planet carrier output terminal is applied in the output of casing, has replaced traditional output to connect with pin by bolt with the secondary planet frame, can reduce machining error, guaranteed machining accuracy, alleviated complete machine weight; The output of casing is convenient to dismounting by output terminal cap seal dress, changes oil sealing, cooperates the quenching wear-resistant sleeve to improve working life.
