Description
Technical field
The invention belongs to the bearing lubrication technical field, be specifically related to a kind of bearing lubrication structure of speed reducer, be installed on the lubricating structure of the bearing of driving shaft top in the particularly vertical lift machine speed reducer
Background technique
are present, and all there is slide relative in various degree in rolling bearing between inner member in operation process; Thereby cause frictional heating and component abrasion; In order to reduce wearing and tearing, to prevent corrosion, avoid because of frictional heating causes that operating temperature is too high, must carry out lubricated reliably.The lubricating method of bearing roughly is divided into two kinds of grease lubrication and oil lubrications.The bearing structure simplicity of design of grease lubrication, lubricating grease can play very big seal action, and maintenance cost is low, long service life.But the character of lubricating grease is stable not as lubricant oil, and friction power loss is big, should not be in high speed and the big applications of temperature variation.So in the next employing oil lubrication of condition of high speed, high temperature, during oil lubrication, oil film formation and complementarity are good, also play the cooling heat dissipation effect, reduce the temperature rise of bearing.
are as shown in Figure 1; Vertical lift machine speed reducer structure in the existing technology; Described speed reducer comprises worm shaft 1, main shaft 2, worm gear 3, casing 4; The two ends of worm shaft 1 place on the casing 4 through a pair of rolling bearing rotationally, and an end of worm shaft 1 extends to that casing 4 is outer to link to each other with the motor (not shown), and the axial dependence worm shaft of worm shaft 1 covers 9 thoroughly to be pushed down the outer ring of bearing 6 and realize axially locating.On casing 4, main shaft 2 middle cover are equipped with worm gear 3 through the rolling bearing hub setting for main shaft 2, the transmission that is meshing with each other of worm gear 3 and thread section 101 on the worm shaft 1.The inboard, lower end surface that is installed on the bearing 6 of worm shaft 1 top is pressed against on the axle rank of worm shaft 1, and the outside, lower end surface of bearing 6 is pressed against on the oil sealing base 7, is arranged with first oil sealing 8 between oil sealing base 7 and the worm shaft 1.Covered 9 thoroughly by worm shaft outside the upper-end surface of bearing 6 and push down the axially locating that realizes worm shaft 1, worm shaft covers thoroughly and also is provided with second oil sealing 10 between 9 middle part inner rings and the worm shaft 1, and the inboard, upper-end surface of bearing 6 is fixed by locking nut 12.In this structure, be added with lubricating grease in the bearing 6, when sneaking into moisture, dust, abrasive dust, be difficult to separate; When worm shaft 1 under hot environment during high-speed rotation, the bad stability of lubricating grease, frictional force is apart from bigger; The wearing and tearing power consumption becomes big, causes vibration, noise, and bearing life reduces greatly; So replacing lubricating grease that just need be frequent under this operating mode, but, the pipeline and the used lubricating grease trap of collection of supply and eliminating lubricating grease just must be set in order to change lubricating grease; Cost is high, and structural design is all more loaded down with trivial details with the replacing maintenance process.So under the operating mode of high temperature and high speed; This structure need be used oil lubrication instead, through the circulation of lubricant oil, takes away bearing great amount of heat on every side; And wash away impurity; But lubricant oil is prone to flow, thus need a kind of bearing lubrication structure of design with good guarantor's functional oil, with being transported in the bearing part of lubrication oil circulation.
For this reason, the applicant has carried out actively and effectively attempting, and the technological scheme that will introduce below produces under this background
Summary of the invention

Application examples:
Narrate working principle of the present invention below in conjunction with Fig. 2,3,4:
Can be added with lubricant oil in the gear reduction box of
lift machine and be used for lubricated cooling driving gear pair, prolong the working life of gear pair.In embodiment 1, when the electrical power of lift machine, motor shaft drives worm shaft 1 to right rotation; The rotation of worm shaft 1 drives the worm gear 3 that is engaged with again and is rotated counterclockwise, at this moment, and thread section 101 and worm gear 3 engagement rotations; Lubricant oil in the casing 1 is got rid of in the filler opening 501 of axle sleeve 5 into; Axle sleeve 5 filler openings 501 interior lubricant oil are transported to rapidly in the bearing 6 through the oil outlet 111 on the spiral chute on the shaft part 103, groove 102 and the bearing washer 11 under action of centrifugal force because worm shaft 1 high-speed rotation, quilt are got rid of into, and the engagement driving of worm and gear makes the lubricant oil in the bearing 6 keep certain amount; Because the heat that the rolling friction of bearing 6 produces heats up the lubricant oil in the bearing 6; Cause the low lubricant oil of temperature to be in the bottom of bearing 6, the lubricant oil that temperature is high is in the top of bearing 6, can change sense of rotation during owing to lift machine work; When motor shaft drives worm shaft 1 to anticlockwise; The worm gear 3 that is engaged with is rotated counterclockwise, and the higher lubricant oil of temperature that is in bearing top is back in the speed reducer along spiral chute 103 through filler opening 111 and groove 102, and the lubricant oil that temperature is low is still stayed lubricating bearings 6 in the bearing 6.According to said process, when worm shaft 1 became again to right rotation again, the lubricant oil in the casing 1 was transported to again in the bearing 6, and guaranteeing has enough lubricant oil to be lubricated around the bearing.Worm shaft 1 left-handed and dextrorotation at interval makes the cooling of flowing of the lubrication oil circulation around the bearing 6, and lubricating bearings 6 preferably, takes away the heat around the bearing 6, washes away the impurity in the bearing 6.
In embodiment 2, the lubricant oil in the casing 4 gets into from the filler opening 501 of axle sleeve 5, through the spiral chute 132 on the thread bush 13 and second groove 131 lubricant oil is transported in the bearing 6
.In embodiment 3; Lubricant oil in the casing 4 gets into from the filler opening 141 of second axle sleeve 14; Through the spiral chute on inner spiral groove on second axle sleeve 14 142 and the worm shaft 1 105 lubricant oil is transported to top, gets in the bearings 6 through groove 102 and filler opening 111 again.All the other are with the description to embodiment 1.
In order to improve the efficient of oil transportation, the spiral chute described in above-mentioned each embodiment can be unidirectional double end or multi-head spiral groove
