Abstract
The invention discloses a lifting nut comprising a nut support, a sleeve, an upper nut and a lower nut, wherein the upper nut and the lower nut are of a cylindrical shape and both arranged in the sleeve; both ends of the sleeve are respectively provided with an end cover; the upper nut and the lower nut are connected together by a screw; the sleeve is connected to the nut support; the radial joint of the upper nut and the lower nut is jointed with a connecting through hole; and the connecting through hole passes through the side wall of the sleeve. In the lifting nut in the scheme of the invention, a gap exists among the upper nut and the lower nut which are connected to the sleeve and the sleeve so that the nut can rotate in the sleeve and also move in the Z-axis direction; and the sleeve can also move along the X-axis direction and also rotate around an X axle, so that compensation can be realized in more directions, no blockage phenomenon is generated between the lifting nut and a screw rod during movement, then a lifting table can freely lift, and the service life of the lifting nut is prolonged.
Description
Technical field
The present invention relates to a kind of transmission device, relate in particular to a kind of lifting nut.
Background technique
Lifting drive system mainly is made up of turn-screw, lifting nut and transmission system, and transmission system is given leading screw with transmission of power, and lifting nut rotates the drive raising platform with leading screw and moves up and down, and lifting nut and leading screw are bearing the total weight of raising platform at work.The lifting nut that uses at present comprises nut support, sleeve; Be arranged on clip nut in the sleeve, the lifting nut of this kind structure has only along X axis move left and right with around two degrees of freedom of X axle rotation, because there is processing in leading screw, equal error is installed; Be difficult to guarantee the straightness of leading screw; Often the jam phenomenon occurs so lifting nut moves on leading screw, the lifting nut wearing and tearing are accelerated, shorten working life.
Summary of the invention
Technical problem to above-mentioned existence the objective of the invention is: proposed a kind of reducing wear, increased the lifting nut in working life.
Technical solution of the present invention is achieved in that a kind of lifting nut, comprises nut support, sleeve, upper cap nut, lower nut; Said upper cap nut, lower nut profile are cylindrical body, all are arranged in the sleeve; Said sleeve two ends are respectively equipped with an end cap; Said upper cap nut and lower nut link together through screw; Said sleeve is connected on the nut support; Said upper cap nut, lower nut radial abutment place butt joint connecting through hole; Said connecting through hole is through sleeve lateral wall.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
A kind of lifting nut of the present invention is connected between upper and lower nut and the sleeve in the sleeve and has the gap, so nut can rotate at sleeve, can move axially along Z again; And sleeve also can move along the X axial direction, can rotate around the X axle again, and a plurality of like this directions all can be compensated, and making is in operation between lifting nut and the leading screw can not produce the jam phenomenon, and raising platform is gone up and down freely, thereby has prolonged the working life of lifting nut.
Description of drawings
Below in conjunction with accompanying drawing technological scheme of the present invention is described further:
Accompanying drawing 1 is the structural representation of a kind of lifting nut of the present invention;
Accompanying drawing 2 is that the A-A of a kind of lifting nut of the present invention is to sectional view;
Wherein: 1, nut support; 2, sleeve; 3, upper cap nut; 4, lower nut; 5, end cap; 6, screw; 7, connecting through hole.
Embodiment
Below in conjunction with accompanying drawing the present invention is described.
Accompanying drawing 1 is a kind of lifting nut of the present invention, comprises nut support 1, sleeve 2, upper cap nut 3, lower nut 4; Said upper cap nut 3, lower nut 4 profiles are cylindrical body, all are arranged in the sleeve 2; Said sleeve 2 two ends are respectively equipped with an end cap 5; Said upper cap nut 3 links together through screw 6 with lower nut 4; Said sleeve 2 is connected on the nut support 1; Said upper cap nut 3, lower nut 4 radial abutment places butt joint connecting through hole 7; Said connecting through hole 7 is through sleeve 2 sidewalls.
The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage that is familiar with this technology can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
