Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and examples.
Fig. 1 is a front view of the automatic lubrication device of the present invention.
Fig. 2 is a top view of the automatic lubrication.
FIG. 3 is a view of the lubrication hole of the slewing bearing and the fixing hole of the lubrication pipe.
The utility model provides an automatic lubricating system of a slewing bearing, which comprises a lubricating control cabinet 2, a main oil pipe 3, an oil pipe fixing seat 4, a slewing bearing 5, an oil pipe fixing frame 6, a branch oil pipe 7 and a distributor 8, wherein three rows and eight rows of lubricating holes 9 are arranged on the outer ring of the slewing bearing 5, and oil pipe mounting fixing holes 10 are arranged on the left side and the right side of the lubricating holes 9; lubrication control cabinet 2 includes hydraulic pump, batch oil tank and PLC, and when the time that the signal of gathering from the cab gave 2 rotation mechanism operation of lubrication control cabinet arrived the lubricated time that lubrication control cabinet 2 set for, the signal was given and is let gyration lubricating system automatic start, and the lubricating pump begins work, and the lubricating pump absorbs out lubricating grease in the oil storage bucket and directly distributes respectively through four main oil pipe 3 after the pressurization to four distributors 8, carries respectively to each lubrication point on through branch road oil pipe 7 by distributor 8 again.
The main oil pipe 3 is fixed on the upper bearing seat 1 through an oil pipe fixing seat 4.
The branch oil pipe 7 is fixed on an oil pipe mounting fixing hole of the slewing bearing 5 through an oil pipe fixing frame 6 and an oil pipe fixing seat 4, and the branch oil pipe 7 injects grease to the slewing bearing through a lubricating hole 9.
