Problems solved by technology
The existing oil distributor has an oil pipe between the oil inlet nozzle and the oil outlet nozzle. In actual use, because the oil distributor at both ends does not rotate with the central axis, the oil pipe will be twisted and cause accidents.
At present, the structure of the oil distributor in the domestic market is complex and inconvenient to maintain

Embodiment Construction
[0009] Such as figure 1 As shown, the rotary oil distributor includes a cylindrical shell 3, a core 6 located in the shell 3, a bottom plate 1 fixed to one end of the shell 3, and a dust cover fixed to the other end of the shell 3 7. It is characterized in that: a number of oil inlets 4 are arranged on the housing 3 along the length direction of the housing; the core body 6 and the housing 3 are in clearance fit and bearings 2 are installed at both ends thereof, An annular groove 5 corresponding to the oil inlet 4 is arranged radially on its outer circle; an oil outlet 8 having the same number as the oil inlet 4 is arranged on the end face of the core body 6 near the dust cover 7; The oil outlet 8 communicates with the annular groove 5 through an independent oil passage.
[0010] How to use and working principle
[0011] When the present invention works, the oil enters through the oil inlet 4 on the housing 3, enters into each annular groove 5 of the core body 6 respectively...

The invention belongs to the technical field of hydraulic lubrication, and in particular relates to a rotary oil way distributor. The rotary oil way distributor comprises a cylindrical shell, a core body, a bottom plate and a dustproof cover, wherein the core body is positioned in the shell; the bottom plate is fixedly connected with one end of the shell; and the dustproof cover is fixedly connected with the other end of the shell. The rotary oil way distributor is characterized in that a plurality of oil inlets are formed on the shell along the length direction of the shell; the core body is in clearance fit with the shell; bearings are arranged at the two ends of the core body; annular grooves corresponding to the oil inlets are formed on the excircle of the core body along the radial direction; oil outlets with the number the same as that of the oil inlets are formed on the end face, adjacent to one side of the dustproof cover, of the core body; and the oil outlets are communicated with the annular grooves through independent oil ways. The rotary oil way distributor is simple in structure, convenient to assemble and safe and reliable in work and solves the problem about oil supply of rotary motion mechanical equipment under the high-speed rotating condition of the core body.
Description
technical field [0001] The invention belongs to the technical field of hydraulic lubrication, and in particular relates to a rotary oil circuit distributor. Background technique [0002] Rotary worktables are widely used in domestic forging equipment, and rotary oil circuit distributors are required to meet the supply of oil in the rotating working state. The existing oil distributor is provided with an oil pipe between the oil inlet nozzle and the oil outlet nozzle. In actual use, because the oil distributor at both ends does not rotate with the central axis, the oil pipe will be twisted and cause accidents. At present, the oil circuit distributors in the domestic market have complex structures and are inconvenient to maintain. Contents of the invention [0003] The object of the present invention is to overcome the disadvantages of unreasonable structure of the existing oil distributor, and provide a rotary oil distributor with simple structure, convenient installation,...
