Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further detailed explanation.
As shown in Figure 1, a kind of lubrication system of screw-bearing, wherein, comprises fixing bearing block 2, is arranged at the ball bearing 3 in this bearing block 2 and is communicated with the lubricant oil road structure of this bearing block 2, ball bearing 3; Cavity is had between described bearing block 2 and screw rod 1, the first lubricant passage way 5 is provided with between this cavity and bearing block 2, be provided with the second lubricant passage way 6 between described cavity and ball bearing 3, the ball 4 that this first lubricant passage way 5 circulates in described ball bearing 3 is communicated with described second lubricant passage way 6; Described first lubricant passage way 5 and the second lubricant passage way 6 form described lubricant oil road structure.Screw rod 1 is arranged in ball bearing 3, and ball bearing 3 comprises inner ring and outer shroud, and ball 4 is limited between this inner ring and outer shroud.From bearing block 2 lateral surface, inside side has through hole along screw rod 1 radial direction, and this through hole and cavity connects form the first lubricant passage way 5.Ball bearing 3 end being positioned at screw rod 1 end is provided with row's oil outlet, and the space between this outlet and the ball 4 of bearing is communicated with, and forms the second lubricant passage way 6.Lubricating oil injects from the import of the first lubricant passage way 5 and enters into cavity, lubricating oil flows to from the top of cavity, through screw rod 1 bar part stream and gather the bottom of cavity, lubricating oil flows to the space between bearing ball 4 and ball 4 from the bottom of cavity again, and slowly the majority of the ball 4 of ball bearing 3 bottommost is soaked, automatically to overflow after the amount of lubricating oil exceedes the immersion height of this ball 4 and outlet through the second lubricant passage way 6 is flowed out.
Wherein, the top of described first lubricant passage way 5 is the import of lubricant oil road structure, and the end of described second lubricant passage way 6 is the outlet of lubricant oil road structure.One oil pipe 9 is connected with this import by connecting head 8, and the end of connecting head 8, for being provided with externally threaded hollow shaft portion, establishes female screw portion to match with this import department.
Wherein, described import is connected with oiling machine, and described outlet is connected with waste oil collecting case.Lubricating oil is injected lubricating oil by oil pipe 9, connecting head 8 toward import by oiling machine.
Wherein, leave space between described bearing block 2 and screw rod 1, and by water proof ring 7, described gap seals is formed described cavity.The effect of water proof ring 7 has two, and first is make ball bearing 3 waterproof, prevents ball bearing 3 from getting rusty; Second is the annular seal space ensureing ball bearing 3 inside, prevents the leakage of lubricating oil from causing and lubricates unsuccessfully, thus the normal running of impact.
Wherein, described cavity is toroidal cavity, makes the flowing of lubricating oil more smooth.
A lubricating method for the lubrication system of screw-bearing, comprises the following steps: oiling, passes into lubricating oil from the import of described lubricant oil road structure; Soak ball bearing 3, the ball 4 in ball bearing 3 soaks by lubricating oil to be implanted; Oil extraction, regularly reinject lubricating oil, and lubricating oil is freely discharged from outlet.
Wherein, the time interval of injecting lubricating oil is one minute.
Operation principle of the present invention: lubricating oil injects from the import of the first lubricant passage way 5 and enters into cavity, lubricating oil flows to from the top of cavity, through screw rod 1 bar part stream and gather the bottom of cavity, lubricating oil flows to the space between bearing ball 4 and ball 4 from the bottom of cavity again, and slowly the majority of the ball 4 of ball bearing 3 bottommost is soaked, automatically to overflow after the amount of lubricating oil exceedes the immersion height of this ball 4 and outlet through the second lubricant passage way 6 is flowed out.
Above embodiment is merely illustrative and not limiting to the invention, therefore all equivalences done according to the method described in patent claim of the present invention change or modify, and are included in patent claim of the present invention.
