Abstract
The utility model relates to an edge transmission speed reducer which comprises an upper box body, a lower box body, an input gear shaft and an output shaft system. The input gear shaft and the output shaft system are parallel, the input gear shaft and the shaft of the output shaft system are supported by bearings at the combination part of the upper box body and lower box body, a gear on the input gear shaft is meshed with a rigid gear-face output large gear in the output shaft system, and an foot installation hole is arranged on a border at the bottom part of the lower box body. The edge transmission speed reducer is characterized in that the height of the lower box body is larger than the radius of the gear on the input gear shaft and smaller than 3/4 of that of the output large gear in the output shaft system, and an oil bottom shell is arranged at the bottom part of the lower box body. The edge transmission speed reducer has the advantages that: as the gravity center is low, the shock in working is relatively weak, the stability is good, and impacts on the gear surface, the bearings and a connecting bolt are weak; as the speed reducer adopts sealing devices comprising an oil seal, a penetrating cover, an oil slinger and an oil baffle and an oil return passage is arranged on the lower box body, oil leakage cannot be easily incurred; as the two ends of the input gear shaft are all input shafts, the power input direction of the speed reducer can be selected.
Description
Technical field
The utility model relates to a kind of speed reducer, in particular for the edge transmission speed reducer of cement grinding mill, coal mill.
Background technique
Because it is big that hardened face gear has bearing capacity, volume is little, and is in light weight, efficient and high reliability features, can make that the Performance And Reliability of main frame improves greatly in the every profession and trade, therefore hard flank of tooth retarder has become the main flow of domestic and international geared machine development since the eighties from last century.China has worked out the series standard of several hard flank of tooth retarders in succession in late nineteen eighties the early 1990s in last century, as ZBJ19004-88, YB/T050-93 etc.
The edge transmission speed reducer is mainly used in pebble mill, grinding machine is because the employing steel ball is a grinding body, vibrations are big in the work, inertia is big, noise is big, and traditional edge transmission speed reducer adopts upper box, lower box, parallel input gear shaft and output shaft system, the axle of input gear shaft and output shaft system is by the connecting part of bearings in upper box 1 and lower box 2, hard flank of tooth output gearwheel engagement in gear on the input gear shaft and the output shaft system, lower box 2 bottom frames are provided with lower margin mounting hole (referring to Fig. 1), center of gravity is higher, vibrations are big, less stable, leakage of oil very easily appears in the use, damage of bearings, impaired or the broken teeth of the flank of tooth, and fault such as attachment bolt is bad influence the proper functioning of grinding machine.
Summary of the invention
The purpose of this utility model is: higher at the center of gravity that the edge transmission speed reducer of present use exists, vibrations are big, less stable, leakage of oil, damage of bearings very easily appear in the use, the flank of tooth is impaired or broken teeth, and fault such as attachment bolt is bad, influence the problems such as proper functioning of grinding machine, a kind of new edge transmission speed reducer is provided.
The purpose of this utility model is achieved in that a kind of edge transmission speed reducer, comprise upper box, lower box, parallel input gear shaft and output shaft system, the axle of input gear shaft and output shaft system is by the connecting part of bearings in upper box and lower box, hard flank of tooth output gearwheel engagement in gear on the input gear shaft and the output shaft system, lower box bottom frame is provided with the lower margin mounting hole, it is characterized in that: the radius that the height of lower box cogs greater than the input gear shaft, less than 3/4ths of output gearwheel radius in the output shaft system, the lower box bottom is provided with oil sump.
In the utility model: the two ends of input gear shaft are input shaft, and the hard flank of tooth output gearwheel in the output shaft system is made up of bucket-shaped wheel hub and the hard flank of tooth external toothing that is installed on the bucket-shaped wheel hub.
In the utility model: be equipped with seal arrangement on the output shaft in the input shaft of input gear shaft and the output shaft system.
In the utility model: described seal arrangement comprises oil sealing, saturating lid, disc and oil baffle, also is provided with drainback passage on the described lower box.
Advantage of the present utility model is: owing to reduced the actual height of lower box, can reduce the as installed height of speed reducer, and low in center of gravity, vibrations are less relatively in the work, stability is better, and relative less to the influence of the flank of tooth, bearing and attachment bolt, damaged condition is lighter; Because the seal arrangement that adopts on the output shaft in the input shaft of input gear shaft and the output shaft system comprises oil sealing, saturating lid, disc and oil baffle, also is provided with drainback passage on the described lower box, is not prone to leakage of oil; Input gear shaft two ends are input shaft, can select the power input direction of a selection speed reducer according to the situation of grinding machine.
