Description
Technical field
The present invention relates to speed reducer field, be specifically related to ladle turret special vertical star wheel reducer.
Background technique
Ladle turret is one of key equipment of casting machine, play the important function that connects upper and lower two procedures, its drive unit should guarantee that the rotation of ladle turret is steady, accurate positioning, and ladle turret impact to drive part in the time of start and stop is larger, under ladle turret, driver element segment space is limited, needs to install the equipment such as speed reducer, motor, motor and pivoting support simultaneously, and speed reducer size is had relatively high expectations.And now use speed reducer volume excessive, and speed reducer comprises that motor installs more difficultly, when staff keeps in repair, operating space is limited and now use the transmission accuracy of speed reducer own not high enough, easily causes traverse platform rotation not steady, locates not accurate enough.
Summary of the invention
In order to solve in prior art the deficiencies such as ladle revolving dial speed reducer volume is large, transmission accuracy is not high, operation noise is higher, installation and maintenance are inconvenient, the object of this invention is to provide a kind of simple and compact for structure, velocity ratio and greatly, all carry the vertical star wheel reducer of the special two-way input of ladle turret that performance is good, transmission accuracy is high, noise is relatively low.
For reaching above object, the technological scheme that the present invention takes is:
A kind of ladle turret special vertical star wheel reducer, comprise casing, input shaft, jack shaft, one-level spiral bevel gear pair, more than one-level star-wheel unit and output shaft, described input shaft level is installed on the bottom of casing, described jack shaft at right angle setting is in casing, described input shaft and jack shaft are through one-level spiral bevel gear pair commutation transmission, described output shaft is arranged at the top of casing, output shaft and middle coaxial setting the star-wheel unit connection for transmission more than one-level, described star-wheel unit comprises eccentric bushing, capacity eccentric bearing and planetary pinion, described eccentric bushing is fixedly sleeved in jack shaft, on described eccentric bushing, cover has two capacity eccentric bearings, on described two capacity eccentric bearings, be respectively socketed with planetary pinion, described planetary pinion respectively with casing inner wall on ring gear engagement driving, the top of described star-wheel unit is provided with supporting disk, the bottom of star-wheel unit is provided with lower support dish, described two planetary sides are through more than one back shaft and more than one eccentric shaft and upper, lower support dish connects, described upper supporting disk is fixedly connected with output shaft.
Further, two capacity eccentric bearings that are socketed on described eccentric bushing are 180 ° of phase differences.
Further, described ring gear and casing are integrated part.
Further, the outside of casing is stretched out at the two ends of described input shaft.
Further, the socket of described lower support disk activity and jack shaft be supported on internal side of shell through bearing.
Again further, described upper supporting disk is connected to jack shaft through bearing housing, and the top of upper supporting disk is fixedly connected with through threaded piece with output shaft.
Take after above technological scheme, beneficial effect of the present invention is:
Input shaft designs for double input, and Applicable scope is wider; Speed reducer is vertical design, and output shaft is upwards installed, and input shaft is 90 ° of angles perpendicular to speed reducer center line, and attachment face, on speed reducer top, has reduced speed reducer center of gravity, avoids rocking of the too high generation of center of gravity; The little tooth portion of planet gearing modulus gap is little, precision is high, velocity ratio is large.
