Description
Technical field
The utility model belongs to the vertical roll grinder technical field, especially is a kind of modified grinding roller axle that is used for grinding roller bearing lubrication.
Background technology
Grinding roller is the vitals of vertical roll grinder, mainly works to roll material, and working environment is very abominable, and operating ambient temperature is up to more than 200 degree.Because the particle and the humidity of material are inhomogeneous, grinding roller will fluctuate along with the bed thickness of material by the pressurization of loading system, grinding roller is bearing very large pressure and impulsive force, this has good lubricating status with regard to the bearing that requires to be installed on the grinding roller, the cleaning of this outer bearing and cooling are directly connected to the service life of grinding roller or bearing, also are related to the stable operation of vertical roll grinder.
Grinding roller is installed on the grinding roller axle by the bearing at two ends, and actionless grinding roller axle has certain gradient, and grinding roller rotates around the grinding roller axle by bearing under other power drive.The place design that bearings at both ends is installed in grinding roller has a grinding roller chamber, and the grinding roller chamber can store lubricating oil so that lubricating bearings.Because the grinding roller axle is solid shafting, so grinding roller and grinding roller axle a certain amount of lubricating oil of adding in the grinding roller chamber earlier before assembling, but along with its lubricating oil of operation of vertical roll grinder can reduce gradually, it is unfavorable to bring bearing.
Summary of the invention
For addressing the above problem, the utility model has designed a kind of modified grinding roller axle that is used for grinding roller bearing lubrication, finish oil supply and pump-absorb action by fuel feed hole, spill port and the passage set up at the grinding roller axis, improved the lubricated environment of bearing, improved the service life of bearing, strengthen the stability of a system of vertical roll grinder, increased service efficiency.
For achieving the above object, the utility model adopts following technical scheme:
The described modified grinding roller axle that is used for grinding roller bearing lubrication is to join to be drilled with fuel feed hole, passage and spill port on the axis of former grinding roller axle, wherein spill port is arranged on the central axis of grinding roller axle and extends through 1/2 of grinding roller shaft length from an end face of grinding roller axle and divides external cylindrical surface both sides to the grinding roller axle again, takes back oil pipe at the spill port first line of a couplet; What passage was arranged on the oblique upper of spill port and extended through the grinding roller shaft length is folded to the external cylindrical surface upside of grinding roller axle less than 1/2 place, connects tracheae at the passage first line of a couplet; Fuel feed hole is arranged on another oblique upper of spill port and runs through whole grinding roller axle, fuel feed hole and passage are the center with the spill port and are distributed on the identical external diameter and are the distribution of falling the isosceles triangle, the axis of fuel feed hole and passage and the central axis of spill port are parallel to each other, and the fuel feed hole first line of a couplet taps into oil pipe.
Because adopt aforesaid technical scheme, the utility model produces following good effect:
1, guaranteed that lubricating oil maintains normal oil level in the grinding roller chamber, it is better lubricated that bearing is obtained, and alleviates the bearing wear situation.
2, the temperature that has guaranteed bearing is unlikely to too high, makes bearing obtain stable oil film protection.
3, the lubricating oil in the grinding roller chamber is in good cyclic process all the time.
Description of drawings
Fig. 1 is the grinding roller axle construction schematic diagram after improving;
Fig. 2 be Fig. 1 A to the rotation schematic diagram.
Among the above-mentioned figure: the 1--breather pipe; The 2--oil inlet pipe; The 3--oil return pipe; 4--grinding roller axle; The 5--grinding roller; The J--fuel feed hole; The Q--passage; The H--spill port.
The specific embodiment
In conjunction with Fig. 1-2, the modified grinding roller axle that the utility model is used for grinding roller bearing lubrication is to join to be drilled with fuel feed hole J, passage Q and spill port H on the axis of former grinding roller axle, wherein spill port H is arranged on the central axis of grinding roller axle and extends through 1/2 of grinding roller shaft length from an end face of grinding roller axle and divides external cylindrical surface both sides to the grinding roller axle again, takes back oil pipe 3 at the spill port H first line of a couplet; What passage Q was arranged on the oblique upper of spill port H and extended through the grinding roller shaft length is folded to the external cylindrical surface upside of grinding roller axle less than 1/2 place, connects tracheae 1 at the passage Q first line of a couplet; Fuel feed hole J is arranged on another oblique upper of spill port H and runs through whole grinding roller axle, fuel feed hole J and passage Q are the center with spill port H and are distributed on the identical external diameter and are the distribution of falling the isosceles triangle, the central axis of the axis of fuel feed hole J and passage Q and spill port H is parallel to each other, and the fuel feed hole J first line of a couplet taps into oil pipe 2.
The grinding roller axle of installing after improving should notice that fuel feed hole J and passage Q (indicate with the assembling graduation mark) all the time up, passage Q position in the grinding roller chamber is than spill port H height like this, passage Q outside links to each other with breather pipe 1, the grinding roller cavity communicates with the external world, pressure reduction is little, has effectively avoided lubricating oil outwards to flow out by passage Q.The horizontal line of spill port H exit position is in the middle and upper part of bearing after installation, this has just guaranteed that the lubricating oil liquid level is not less than this position all the time in the grinding roller chamber, thereby each roller that makes grinding roller bearing when rotating can both obtain well lubricated, bearing temperature also can reduce by the circulation of lubricating oil, guarantees the cooling effect of bearing.Oil inlet pipe links to each other with oil-feed pump in the Hydraulic Station, and oil return pipe links to each other with scavenge oil pump in the Hydraulic Station, and the flow selected for use of scavenge oil pump is greater than the flow of oil-feed pump in addition, can guarantee that oil return is smooth and easy.
During work, oil-feed pump is pressed into the lubricating oil in the Hydraulic Station fuel feed hole J of grinding roller axle 4 through oil inlet pipe 2, because the end face of grinding roller is by gland seal, lubricating oil can be back in the grinding roller chamber, and scavenge oil pump will be withdrawn into the lubricating oil that surpasses on the oil level line in the Hydraulic Station by oil return pipe 3 when the lubricant level in the grinding roller chamber reaches the residing position of spill port level.Exceed oil because the flow of scavenge oil pump greater than the flow of oil-feed pump, guarantees can not produce in the grinding roller chamber, breather pipe 1 then plays and guarantees to communicate with the external world in the grinding roller chamber, avoids scavenge oil pump to be pumped into negative pressure in the grinding roller chamber, thereby destroys the circulation of lubricating oil.Bearing is in a good lubricated environment all the time like this, has prolonged the service life of bearing, thereby makes the operation of vertical roll grinder more stable, and efficient is higher.
