Abstract
The utility model relates to a lifting mechanism, in particular to an inclined rolling needle bearing lifting mechanism which comprises an inner rolling needle shaft (4), an outer rolling needle sleeve (3) and a holding rack (1), wherein a groove used for holding rolling needles and parallel to an axis in the holding rack (1) is formed into an inclined groove; the rolling needles are put into the inclined groove; the outer rolling needle sleeve (3), the rolling needles (2) on the holding rack (1) and the inner rolling needle shaft (4) are assembled in an interference manner; the rolling needles (2) are driven to rotate by rotating the inner shaft (4), so that the outer rolling needle sleeve (3) moves vertically. The mechanism is small, exquisite, light and convenient in structure and simpler to assemble.
Description
Technical field
The present invention relates to a kind of elevator mechanism, be specifically related to a kind of tiltedly needle bearing elevator mechanism.
Background technique
Turbine and worm, as lifting structure, applies to large corporation conventionally, in dumbwaiter structure, heavy and lifting step is slow, takes up room larger, not high in small-sized lifting structure middle gear tooth bar stability, and bearing capacity is inadequate.Ball screw is the stable elevator mechanism of comparative maturity now.
Summary of the invention
The present invention is intended to reduce the cost of dumbwaiter structure, and making is a kind of simple in structure, the oblique needle bearing elevator mechanism that stability is strong.
By reference to the accompanying drawings, be described as follows:
A kind of tiltedly needle bearing elevator mechanism, comprise axle 4, needle roller overcoat 3 and retainer 1 in needle roller, the groove paralleling to the axis of placing needle roller on retainer 1 is processed into skewed slot, needle roller is put into skewed slot, needle roller 2 on needle roller overcoat 3, retainer 1, the interior axle 4 interference assemblings of needle roller, drive needle roller 2 to rotate by rotating interior axle 4, thus make needle roller overcoat 3 upwards, move downward.
The angle of the skewed slot on described retainer 1 is to depart from 2～3 °, original axle center.
Beneficial effect:
A kind of tiltedly needle bearing elevator mechanism, provides sizable deformation force by the extrusion-deformation of oblique needle roller, and its structural bearing capacity is very large, only has to rotarily drive needle roller rotation by interior axle and just can make structure move up and down.Structure is small and exquisite, light, assembles simpler.Compared with ball screw, on oblique needle bearing elevator mechanism cost, lower than ball screw, structure is relatively simpler.
Brief description of the drawings
Fig. 1 is retainer plan view;
Fig. 2 is retainer plan view;
Fig. 3 is that retainer is surveyed view;
Fig. 4 is a kind of tiltedly needle bearing elevator mechanism structural representation.
Wherein: 1, axle in retainer 2, needle roller 3, needle roller overcoat 4, needle roller
Embodiment
By reference to the accompanying drawings and embodiment, the present invention is further elaborated.
Retainer 1 in Fig. 1, processes by numerical control machine tool the groove paralleling to the axis of placing needle roller on retainer 1 make skewed slot, is preferably processed into and departs from 2～3 °, original axle center, and needle roller 2 is put into skewed slot, makes oblique needle bearing.
As shown in Figure 4, axle 5 interference in the needle roller 2 on needle roller overcoat 3 and retainer 1 and needle roller are assembled, just can drive needle roller 2 to rotate by rotating interior axle 5, thus make needle roller overcoat 3 upwards, move downward.
There is certain angle in a kind of oblique needle bearing elevator mechanism of the present invention, by the pretension of needle roller overcoat, axle rotation in the situation that in needle roller, needle roller overcoat can be because the effect of axial force, thereby can be upwards, move downward, and reaches the object of lifting.Construction cost of the present invention is cheap, stability is high.
According to the present invention, make a kind of oblique needle bearing elevator mechanism.Be 20mm by an internal diameter, external diameter is 26mm, and the long cylinder for 60mm is got the skewed slot that six gradients are 2.5 degree, and packs the needle roller of corresponding size into.
Should be appreciated that described specific embodiment, only in order to explain the present invention, does not limit the present invention.
Claims (2)
1. an oblique needle bearing elevator mechanism, comprise axle (4), needle roller overcoat (3) and retainer (1) in needle roller, it is characterized in that: upper retainer (1) groove paralleling to the axis of placing needle roller is processed into skewed slot, needle roller is put into skewed slot, needle roller (2) on needle roller overcoat (3), retainer (1), interior axle (4) the interference assembling of needle roller, by rotate interior axle (4) drive needle roller (2) rotation, thereby make needle roller overcoat (3) upwards, move downward.
2. the oblique needle bearing elevator mechanism of one according to claim 1, is characterized in that: the angle of the skewed slot on described retainer (1) is to depart from 2～3 °, original axle center.
