Description
Technical Field
The utility model relates to a relevant part technical field of engine, in particular to engine oil bearing blocks up.
Background
At present, a fixed-shaft gearbox adopted in the engineering machinery industry of China generally adopts a mode that two ends of a shaft are fixed on a box body through bearings, an oil inlet end cover is generally installed at one end of the shaft for lubricating all parts, lubricating oil enters an axial lubricating oil channel after entering a lubricating oil hole of a shaft head from the oil inlet end cover, and then flows into all parts needing to be lubricated through all radial lubricating oil channels. For a wider box body, because the shaft is longer, the axial lubricating oil hole is difficult to be processed in one way to be communicated, even if two ends of the shaft are processed simultaneously, because one end of the shaft ensures a larger aperture, the oil pressure of the lubricating oil hole is ensured to ensure the lubricating effect in the future, the processing aperture of the other end can only be smaller, and because the processing depth of the small aperture end is limited, the oil holes at the two ends are still difficult to be communicated; for this reason, the other end bearing is difficult to be forcibly lubricated and can be lubricated only by spatter. There are problems in that: for the shaft far away from the lubricating oil level, the oil is difficult to reach the bearing part at the shaft end by splashing during splash lubrication to form a lubrication dead angle, so that the fault that the bearing is damaged due to insufficient lubrication often occurs.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art exists, the utility model aims to provide an engine oil bearing blocks up.
The above technical purpose of the present invention can be achieved by the following technical solutions:
the utility model provides an engine oil bearing blocks up, includes integrated into one piece's head and pole portion, head and pole portion all are the cylinder type setting, and two parts are provided with the transition fillet along the circumference junction, set up the screw thread on the outer lane of pole portion, the axle center department of head sets up the logical groove that is the round platform form, is located head one side the pole portion tip has seted up interior hexagonal groove, has seted up the hole that communicates with interior hexagonal groove in the other one end of pole portion, and logical groove, interior hexagonal groove and hole triplex all set up with the centre of a circle, and are linked together in proper order, and the opposite side interval of interior hexagonal groove equals with the diameter of hole, and the effective length ratio of interior hexagonal groove and hole is 5:3, and the pole portion tip that is located hole one side is provided with interior.
To sum up, the utility model discloses the beneficial effect who contrasts in prior art does: compare in current oil bearing and block up, the jam structure of this application is more reasonable, and is more convenient in the aspect of processing and installation.
