In oil-well drilling equipment, oil drilling rotating disk gear-box be by the rotating speed of motor and and torque axis change the special gear box of the required rotating speed of rotating disk and moment of torsion into.Because oil drilling rotating disk even uses under the complex working condition of ultradeep well drilling at deep-well with gear-box, need meet the usage requirement such as high-power, compact structure, long-time continuous firing, the oil leakage phenomenon lubricated and input end of input shaft is affect the persistent ailment that this type of gear-box is normally worked.How to improve the lubrication effect of gear-box input end, alleviate or avoid the oil leakage phenomenon of input end to become people's technical problem in the urgent need to address.
Summary of the invention
The object of the invention is to: the problems such as the oil leakage phenomenon of the lubricated and input end of the input shaft existing for oil drilling rotating disk gear-box, improve a kind of new oil drilling rotating disk gear-box.
The object of the present invention is achieved like this: a kind of oil drilling rotating disk gear-box, comprise casing, input shaft, input bevel gear, output bevel gear, output shaft, and it is characterized in that:
Casing comprises input shaft casing and output shaft casing, after their connecting part slitless connection, is welding as one;
The input end of input shaft casing is provided with bearing housing, and input shaft one end is by bearings in bearing housing, and the other end is by bearings in input shaft casing, and output shaft casing is provided with bearing support, output shaft two ends by bearings in bearing support; Casing is stretched out in one end of input shaft and output shaft, and is furnished with transparent cover and oil sealing;
Input shaft one end is passed through input shaft casing and is entered output shaft casing, and end is provided with input bevel gear, and output shaft is provided with output bevel gear, and input bevel gear and output bevel gear are intermeshing;
On input shaft casing, be at least provided with a pressure lubrication filler opening, lubricant oil enters the bearing that supports input shaft by pressure lubrication filler opening and oil duct, and return opening is located at the below of input shaft casing.
In the present invention: the jacket wall that bearing housing is arranged in below is provided with oil return oil duct by chamber, the front and back communication of bearing, and described return opening is located at the below of the input shaft casing between described input shaft two end supports bearing.
In the present invention: input shaft casing is provided with two pressure lubrication filler openings, their position is corresponding with the two end supports bearing of input shaft respectively.
In the present invention: the spring bearing of input shaft input end is two tapered roller bearings arranged side by side, and the other end is spheric roller bearing; The spring bearing of output shaft output terminal is single row roller bearing, and the other end is spheric roller bearing, and the oil sealing in input shaft and output shaft transparent cover is skeleton-type oil seal; Input bevel gear and output bevel gear are Gleason gear.
In the present invention: the oil sealing in input shaft transparent cover is twice skeleton-type oil seal.
The invention has the advantages that: because the spring bearing of input shaft adopts pressure lubrication mode, the bearing that lubricant oil directly enters support input shaft by pressure lubrication filler opening and oil duct makes it lubricated more reliable, because input shaft casing below is provided with return opening, especially the jacket wall that bearing housing is arranged in below is provided with oil return oil duct the chamber, front and back of bearing is linked up, can make the oil pressure after lubricating decline rapidly, reduce its pressure to skeleton-type oil seal, oil sealing in input shaft transparent cover adopts twice skeleton-type oil seal, and these measures have reduced the possibility of input end seepage.
