Description
Technical field
The utility model relates to a kind of spiral lifting machine part, particularly a kind of elevator nut couplings.
Background technology
Spiral lift is also called screw lift, mainly contains screw motion type and nut sports type two kinds of forms; Screw motion type adopts the rotation of motor drive nut to realize screw rod (leading screw) and is elevated vertically, and nut sports type adopts electric motor driven screw (leading screw) rotation to realize nut and is elevated vertically; Conventional spiral lift thrust range: 0.5t ~ 120t, can separate unit use also can multiple linkage, and hoisting depth is on-demand customized; Different version and assembling form, make spiral lift have easy for installation, use flexibly, many advantages such as compact conformation, volume are little, lightweight, many, the supporting forms of noiselessness, function are many, reliability is high, long service life.Spiral lift is in industry widespread uses such as light industry, photovoltaic industry, metallurgical machinery, robot, auto production line, military industries.
The utility model relates to the nut of nut sports type elevator; Nut and the butt flange of current nut sports type elevator are as a whole, butt flange end face is vertical with screw axis, elevator institute driving arrangement can only move along spiral lift screw axis, gap between rotary screw and nut is very little, threaded connection pair forms three plane restrictions and two rotational restraints, and nut can only along the circumferential direction be rotated.When driven equipment center of gravity not to overlap with screw axis or also have radial load except screw axial load, the equipment driven will produce moment of flexure to drive screw, when moment of flexure is less, the screw rod of spiral lift produces elastic deformation, nut and screw rod relative motion friction force and increases, lethal damage may can not be caused to elevator, when moment of flexure is larger, the screw rod of elevator may be out of shape even bending, friction force increase between lifting nut and drive screw causes jam, and the service life shortening screw pair even causes elevator to damage; When adopting the combination of multiple stage elevator, when the precision difference because of elevator parts makes deviation accumulation arrive larger, the nut of multiple stage elevator interlocks because stroke is different, and driving arrangement also can be caused to damage; For preventing elevator from damaging, although more high-capacity elevator can be selected thus make that drive screw is thicker, drive motor becomes large, be the increase in the cost of elevator and oad be installed, reducing applicability and economy.
Utility model content
Technical problem to be solved in the utility model is to provide a kind ofly can improve elevator fiduciary level, ensure lifter apparatus safe operation, increase the service life and the elevator nut couplings reduced costs.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of elevator nut couplings, comprise outer shroud and inner side arranges threaded inner ring, described outer shroud is vertically fixedly set in outside described inner ring, relatively on the outer wall of described inner ring be provided with two keyways, on the inwall of two described outer shrouds, corresponding described keyway place is provided with the pin stretched in described keyway, the inwall of described outer shroud is provided with the shoe cream room of ring-type with described inner ring contact position, described outer shroud is provided with can to the oil hole of oiling in described shoe cream room, the two ends up and down of described outer shroud are provided with spline plane.
The beneficial effects of the utility model are: inner ring by thread set on screw rod, the outside of outer shroud and elevator drives equipment connection, outer shroud can rely on pin to rotate around inner ring, effectively can discharge two rotational restraints, make can not produce moment of flexure between the lifting nut of spiral lift and screw rod, thus avoid screw pair to damage and bent screws distortion; Multiple stage elevator combinationally uses, and when the speed error added up because of element precision makes the stroke of lifting nut inconsistent, also can not cause nut and screw rod self-locking, can improve elevator fiduciary level, ensures lifter apparatus safe operation, increases the service life.
On the basis of technique scheme, the utility model can also do following improvement.
Further, the inner side of described outer shroud is Internal Spherical Surface shape, and the outside of described inner ring is ectosphere planar, and described outer shroud coupling is sleeved on outside described inner ring.
Further, described keyway is fan groove.
Further, described pin and described outer shroud one-body molded.
Adopt the beneficial effect of above-mentioned further scheme to be: pin and outer shroud one-body molded, pin is combined with outer shroud more firm, promotes the reliability of this device.
Further, described outer shroud rear and front end end face is respectively arranged with coupling link, and described coupling link is bolted on described outer shroud.
Adopt the beneficial effect of above-mentioned further scheme to be: coupling link can carry out spacing to inner ring, inner ring is rotated more steady.
