Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
As shown in Figure 1, 2, a kind of lifting deceleration machine for large cargo, including body 1, body 1 vertical direction sets
Putting leading screw 2, leading screw 2 one end is working end, and the other end is arranged in body 1.It is positioned at the leading screw 2 overcoat worm gear 3 of body 1, machine
Transversely two ends, body 1 side are run through and are rotationally connected worm screw 4, worm screw 4 and worm gear 3 at through part and are rotationally connected, the two of worm screw 4
End overcoat the first taper roll bearing 5, the first taper roll bearing 5 drives worm gear 3 rotation to produce huge for bearing worm screw 4
Radial load, the first taper roll bearing 5 has two, and the first taper roll bearing 5 is while bearing the radial load of worm screw 4
Produce an axial force, owing to the first taper roll bearing 5 disposes inclination side lower contrary, so the axial force produced mutually is supported
Disappear, also can limit the speed that worm screw 4 rotates simultaneously, namely limit the speed that worm gear 3 rotates, owing to worm gear 3 and leading screw 2 are fixed
Connect, the most tentatively limit the speed of leading screw 2 lifting.
As it is shown in figure 1, in order to limit leading screw 2 rising or falling speed further, roll by arranging the second circular cone at the two ends of worm gear 3
Sub-bearing 6 and the 3rd taper roll bearing 7, worm screw 4 between the second taper roll bearing 6 and the 3rd taper roll bearing 7,
The second taper roll bearing 6 and the 3rd taper roll bearing 7 that the two ends of worm gear 3 are arranged are used for undertaking with large cargo screw mandrel
When lifting, worm gear 3 produces huge radial load, and the second taper roll bearing 6 and the 3rd taper roll bearing 7 are simultaneously simultaneously
Limit the rotation of worm gear 3 so that the speed that leading screw 2 raises also arrives restriction, further increase the accuracy of leading screw 2 lifting.
Second taper roll bearing 6 is obliquely installed from bottom to top, bears the radial load of worm gear 3, and creates one simultaneously and incline
Axial thrust load obliquely；3rd taper roll bearing 7 is obliquely installed from top to bottom, bears the radial load of worm gear 3, and
Create an axial thrust load tilted upward simultaneously；Two axial thrust load sizes are identical and in opposite direction, can mutually support
Disappear, it is ensured that worm gear 3 is extended service life.
Owing to first taper roll bearing the 5, second taper roll bearing the 6, the 3rd taper roll bearing 7 is used for bearing lifting
The frictional force of formula reductor operation and the lifting power to weight lifting are very serious, in order to reduce to three bearing wears
The abrasion of bearing, the oil-in 8 arranged by body 1 side adds paste synthetic lithium base grease, so that paste synthesis
Lithium base grease enters in body 1 smoothly, and oil-in 8 is obliquely installed from top to bottom, under gravity, and paste synthesis lithio
Grease can accelerate in body 1.After using a period of time, paste synthetic lithium base grease can lose efficacy, and needs more
Change paste synthetic lithium base grease；The paste synthetic lithium base grease lost efficacy is deposited in the bottom of body 1, sets bottom body 1
The oil-out 9 put for discharging the paste synthetic lithium base grease of inefficacy, dismounting be sealed in oil-out 9 for accumbency " E " shape
Plug 10 can discharge the paste synthetic lithium base grease of inefficacy；After cleaning out, plug 10 is being sealed hydraulic fluid port 9
, in order to seal and facilitate dismounting plug 10, plug 10 is set to accumbency " E " shape, and arranges at the two ends of plug 10
Flange, flange clasps body 1；Further conveniently dismantling and seal hydraulic fluid port 9, plug 10 uses elastomeric material to make；Simultaneously
Paste synthetic lithium base grease is oiliness, and in order to extend the service life of plug 10, plug 10 has the material of oil repellent and makes,
So the elastomeric material that plug 10 uses oil repellent is made.
During elevating screw 2, departing from the trend of worm gear 3 to prevent leading screw 2 from having, worm gear 3 is bottom body 1
Place arranges notch 11, and notch 11 is positioned at immediately below oil-out 9, conflicts in the two ends of pressing plate 13 two ends and worm gear 3, and screw passes
The screw thread mouth 12 of one end that pressing plate 13 and leading screw 2 are arranged in body 1 is fixing to be connected, and the setting of pressing plate 13 and screw is in order to limit
The axially-movable of leading screw 2.
As in figure 2 it is shown, worm screw 4 two ends all through part bodies 1, and two ends are all outfans, it is ensured that limit in landform
Time processed, may be at and motor cooperating for lifting deceleration machine at least one end of large cargo.
This specific embodiment is only that it is not to restriction of the present utility model, ability to explanation of the present utility model
The present embodiment can be made after reading this specification by field technique personnel as required does not has the amendment of creative contribution, but
As long as all being protected by Patent Law in right of the present utility model.
