Description
Technical field
The present invention relates to generator lubricating structure technical field, particularly a kind of bearing of wind power generator lubricating structure.
Background technique
Wind-driven generator many employings lubricant grease carries out bearing lubrication, grease lubrication is higher to oil channel structures designing requirement, bad oil channel structures design can cause multiple adverse consequences: 1. get rid of oil the too fast lubricant grease that causes lack, thus bearing temperature rise too high so that damage bearing; 2. oil extraction does not freely cause lubricant grease to take most of bearing space, and heat dispersal situations is relatively poor, causes bearing temperature rise too high, and grease base oil is oxidized, As time goes on, base oil runs off gradually, leakage, and lubricating grease becomes dry, hardening, bearing loses lubrication, causes damaging.Therefore, need lubricating structure reasonable in design, be unlikely to the excessive lubricating grease that causes of pumping pressure and lack, or pumping pressure is too small, cause waste oil to be discharged not smooth.
Summary of the invention
The object of the invention is to the shortcoming overcoming prior art, a kind of bearing of wind power generator lubricating structure is provided.
Object of the present invention is achieved through the following technical solutions: a kind of bearing of wind power generator lubricating structure, it comprises the right baffle-plate connected successively, main body and right baffle plate, in the axis hole of main body, bearing A is installed successively, left flinger ring, disc, right flinger ring and bearing B, in the axis hole of right baffle-plate, axle sleeve is installed, the top of right baffle-plate is provided with filler opening A and filler opening B, filler opening B is communicated with main body, axle sleeve, the cavity A that right baffle-plate and bearing A surround, main body, right end cap and bearing B surround cavity B, main body is provided with the oil inlet passage being communicated with filler opening A and cavity B, the side, two, left and right of left flinger ring is provided with groove, the right flank of right flinger ring is provided with groove, the left side of left flinger ring presses on the outer ring of bearing A, the left side of right flinger ring presses on the right side of left flinger ring, the right side of right flinger ring presses on the outer ring of bearing B, the circumferential surface of disc is provided with circular fin, circular fin is positioned at the right groove of left flinger ring, the external diameter of the circumferential surface of disc is less than the internal diameter of left flinger ring and right flinger ring, the breach being communicated with right inside grooves space is provided with bottom left flinger ring, the bottom of right baffle-plate is provided with oil drain out, main body is provided with the oil drain passage being communicated with breach and oil drain out.
The left end of the axis hole of described main body is provided with convex edge, and the outer ring of bearing A presses on this convex edge, and axle sleeve presses on the inner ring of bearing A, and right baffle plate presses on the outer ring of bearing B.
The present invention has the following advantages: the present invention devises rational lubricating structure, be unlikely to the excessive lubricating grease that causes of pumping pressure and lack, or pumping pressure is too small, and cause waste oil to be discharged not smooth, this novel lubricating structure fully solves this two problems; Make each bearing have new grease lubrication simultaneously simultaneously, and reasonable in design get rid of oily structure, discharge waste oil by same oil drain out.
The present invention shares the lubricating structure of a bearing chamber than existing wind-driven generator two bearings, in oil-feed, lubricates two bearings simultaneously, instead of after first lubricating a bearing, then lubricate another bearing; Get rid of oily in, by flinger ring reasonable in design and disc, adopt rational pump action, make oil pocket have appropriate oil quantity; In oil extraction, be designed with rational oil drain out, the waste oil that two bearings are thrown away is discharged timely and effectively.
The present invention solves the lubrication problem that two bearings share an oil pocket, and bearing is worked normally.
