Abstract
The utility model discloses a vacuum deaerator reduction box, which comprises a box body (1), a box cover (3), a bearing cover (4), an input gear shaft (5), an output gear shaft (8), an intermediate gear shaft (7) and a driven gear (6), wherein a bearing and a bearing frame (2) for positioning the gear are installed inside the box body (1); and one end of the input gear shaft (5) and one end of the output gear shaft (8) are respectively connected with the bearing frame (2) through bearings. The bearing frame is arranged inside the box body of the reduction box, so that the rotation speed of the reduction box is constant, the reduction box is stable for run, and the service life of the reduction box can be greatly prolonged.
Description
Technical field
The utility model relates to a kind of speed reducer, is specifically related to a kind of running vacuum degasser speed reducer more stably.
Background technique
The structural type of existing vacuum degasser speed reducer generally adopts the two-stage speed change of symmetry; But the input and output gear shaft all is unsettled, not supporting; Gear can be located shakiness like this, is prone to cause heating stuck and cause beating tooth, makes that finally entire equipment can't proper functioning.
The model utility content
The utility model provides a kind of vacuum degasser speed reducer, has solved that vacuum degasser speed reducer middle gear location in the existing technology is unstable to cause the problem that equipment can't proper functioning.
For solving above-mentioned technical problem, the utility model adopts following technological scheme:
A kind of vacuum degasser speed reducer comprises casing, case lid, bearing cap, input gear shaft, output gear shaft, intermediate gear shaft and driven gear, and the bearing support of supporting, Positioning Gear also is installed in the casing; One end of input gear shaft and output gear shaft is connected with bearing support respectively through bearing.
Further technological scheme is, the central position of above-mentioned bearing support is bearings mounted step hole, also is provided with two mistakes around the step hole and lets the through hole of intermediate gear shaft; Also be provided with at least one convex tendon of gaining in strength on the bearing support.
Further technological scheme is that above-mentioned convex tendon has four, is evenly distributed on the bearing support.
Compared with prior art; The beneficial effect of the utility model is: be provided with in the casing of the utility model speed reducer and make accurate, the firm bearing support in gear location; The input gear shaft is connected with bearing support respectively through bearing with output gear shaft; Can make the speed reducer invariablenes turning speed like this, operate steadily, improve the working life of speed reducer greatly.
