Description
Affiliated field:
The utility model belongs to a kind of ball-screw nut rotating nut lubrication system device, is specially adapted to the ball-screw that the vertical rotation mode used rotates for nut.
Background technology:
Along with the develop rapidly of processing manufacturing industry, high speed and super precision machine tool ball screw adopts nut rotation mode to get more and more, and the lubricating system of the ball-screw that traditional screw mandrel rotates can not be applied to the mode of nut rotation.At present, adopt the ball-screw of nut current condition lower nut rotation mode mostly to adopt grease lubrication structure, along with the motion of nut, grease can reduce gradually, needs regularly to increase grease, brings inconvenience, waste time and energy to processing use.
Summary of the invention:
The utility model, for the deficiency existed in the ball-screw nut lubrication adopting nut to rotate, provides a kind of novel leading screw rotating nut lubrication system, avoids the difficulty that grease lubrication needs frequent stuffing.
The utility model said leading screw rotating nut lubrication system, comprises ring flange oil-feed, end cap oil groove and passage, nut shaft sleeve gear way to cycle oil, oil drain pan.Realizing the technical scheme that its technical problem adopts is, by ball-screw screw mandrel, ball-screw nut, nut shaft sleeve gear, ring flange, end cap, oil drain pan, deep groove ball bearing, thrust bearing, oil drain pan, pedestal, on the ball-screw basis of the employing nut rotation of the composition such as key, upper flange plate is provided with oil-in, ring packing oil groove is provided with outside between ring flange and end cap, the passage be communicated on ball-screw nut lubricating oil inlet is provided with in annular oil groove bottom, the nut shaft sleeve gear be connected with ball-screw feed screw nut lubricating oil outlet is provided with oil return through-hole, oil drain pan is provided with shoe cream room and oil-out.
According to the utility model said leading screw rotating nut lubrication system, said upper flange plate is provided with one or more oil-in; Said end cap is provided with ring packing oil groove and grease channel; Said nut shaft sleeve gear is provided with one or more oil return through-hole; Said oil drain pan is provided with shoe cream room and one or more oil-out; Or one or more oil-out can be only provided with on said oil drain pan.
The effect that the utility model has is, oil return through-hole on the nut shaft sleeve gear of lubricating oil after ball-screw lubrication through being connected with ball-screw nut lubricating oil outlet flows out, the lubricating oil flowed out is through the recovery of oil drain pan, flowed out by the outlet on oil drain pan, annular labyrinth seal is provided with outside between ring flange and end cap, lubricating oil splash can be prevented, nut shaft sleeve gear is provided with cannelure, lubricating oil can be made to throw away under the influence of centrifugal force, prevent lubricating oil from flowing on ball-screw screw mandrel, cause splashing.The utility model solves in prior art, and because of the motion of nut, grease reduces gradually, needs the problem regularly increasing grease, avoids the operation that grease lubrication needs frequent fatten.
Accompanying drawing illustrates:
Accompanying drawing 1: leading screw rotating nut lubricating arrangement schematic diagram.
Detailed description of the invention:
What provide in accompanying drawing 1 is the utility model said leading screw rotating nut lubrication system schematic diagram.On the ball-screw basis that the employing nut that leading screw rotating nut lubricating arrangement is made up of ball-screw screw mandrel 1, ball-screw nut 2, nut shaft sleeve gear 3, upper flange plate 4, end cap 5, outward flange dish 6, deep groove ball bearing 7, thrust bearing 8, oil drain pan 9, pedestal 10, key 11 etc. rotates, upper flange plate 4 is provided with one or more oil-ins 12, end cap 5 is provided with annular oil groove 13, is provided with the passage 14 be communicated on ball-screw nut 2 lubricating oil inlet in annular oil groove 13 bottom; Nut shaft sleeve gear 3 is provided with one or more oil return through-hole 15, lubricating oil is after ball-screw screw mandrel 1 lubricates, and the through hole 15 on the nut shaft sleeve gear 3 that is connected with ball-screw spiral shell lubricating oil outlet flows out to oil drain pan 9; Oil drain pan 9 is provided with shoe cream room and one or more oil-out 16, and lubricating oil is flowed out by the oil-out 16 on oil drain pan 9; Be provided with annular labyrinth seal between ring flange 6 and end cap 5 outside, can prevent lubricating oil splash, nut shaft sleeve gear 3 is provided with cannelure 17, and lubricating oil can be made to throw away under the influence of centrifugal force, prevents lubricating oil from flowing on ball-screw screw mandrel, causes splashing.
Ball-screw screw mandrel 1 maintains static, external motor passes through travelling gear, nut shaft sleeve gear 3 is driven to rotate, nut shaft sleeve gear 3 is connected with ball-screw nut 2 by one or more key 11 (only depicting 1 in this example), thus drives ball ball-screw nut 2 to rotate; Due to the effect of ball-screw screw mandrel 1, ball-screw nut 2 moves up and down on ball-screw screw mandrel 1, by thrust bearing 8, promotes pedestal 11 and moves.Ring flange 4 is provided with one or more oil-in, lubricating oil is sprayed onto in the annular oil groove 13 on end cap 5 by oil-in 12, enter into ball-screw nut 2 by the passage 14 on end cap 5 again to lubricate ball, oil after lubrication is flowed out by the through hole 15 of nut shaft sleeve gear 3 bottom, reclaimed by oil drain pan 9, flowed out by oil drain pan 9 oil-out 16.
