Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1-2, the utility model comprises oil ring body 1, the madial wall of oil ring body 1 is provided with three annular grooves 1-1,1-2,1-3, the setting of annular groove 1-1,1-2,1-3, not only alleviate weight of the present utility model, also there is the function of certain band oil, improve lubrication and the heat dispersion of bearing.
Be provided with oil sac 1-4 near the bottom surface of two grooves 1-2,1-3 of oil ring body 1 both ends of the surface, the quantity of oil sac 1-4 is 8, also more than 8, along the circumferential direction can be evenly arranged; Oil sac 1-4 is blind cylindrical hole; Be arranged in middle groove 1-1 and do not establish oil sac.Corresponding to the oil sac 1-4 in groove 1-2, the end face of the close groove 1-2 of oil ring body 1 is provided with oil inlet hole 1-5, and the oil inlet hole 1-5 oil sac 1-4 corresponding with in groove 1-2 is communicated with.Corresponding to the oil sac 1-4 in groove 1-3, the end face of the close groove 1-3 of oil ring body 1 is provided with oil inlet hole 1-5, and the oil inlet hole 1-5 oil sac 1-4 corresponding with in groove 1-3 is communicated with.Oil inlet hole 1-5 is obliquely installed, and the center of oil ring body 1 end oil inlet hole 1-5 is less than the distance of center to the center of oil ring body 1 of oil sac 1-4 place oil inlet hole 1-5 to the distance at the center of oil ring body 1.The setting of oil sac 1-4 and oil inlet hole 1-5, when making the utility model bottom be dipped in oil sump 4, can efficiently by the inclination oil inlet hole 1-5 on end face, lubricant oil is imported to oil sac 1-4, when oil sac 1-4 forwards top to rotating shaft, lubricant oil under gravity, flows out along oil sac 1-4 and lubricates bearing, band oil mass is large, improves lubrication and the heat dispersion of bearing.
The outer side wall of oil ring body 1 is provided with annular guiding groove 1-6, and the cross section of guiding groove 1-6 is rectangle, and during use, guiding groove coordinates with the guiding oil baffle 2 on bearing support, and guiding oil baffle 2 plays spacing effect.Under inclination operating mode, it is spacing that the oil baffle that on the oil ring draw-in groove of sliding bearing on watt and bearing support, left and right horizontal symmetrical is arranged carries out entirety to the utility model, limits of the present utility model waving, improve stability of the present utility model.
