Abstract
The utility model relates to a low-friction non-dead centre gap adjustable high-load universal rolling castor supported by a sphere. A casing is composed of an inner screw sleeve 2, the inner wall of which is cylindrical, and the bottom of which is provided with a central hole, a screw plug 4, an elastic pad 5 and a screw plug 6. The universal rolling castor supported by the sphere is composed of a steel ball 1 arranged in the central hole of the bottom of the inner screw sleeve 2 and a circle of steel balls 3 arranged on the steel ball 1. The steel ball 3 is supported by the screw plug 4, and the screw plug 4 and the screw plug 6 are connected in screw thread with the inner screw sleeve 2. The utility model has the advantages of reasonable design, small friction, no dead point, adjustable gap, large bearing capacity, long service life, etc., and can produce and select the corresponding material and size according to the requirement to produce serial products.
Description
The utility model relates to a kind of improved type cardan wheel, does not particularly have dead point adjustable slit top load spherical support cardan wheel about a kind of low friction.
Existing cardan wheel mainly is made of shell and universal rolling mechanism, the shell of common in the market a kind of cardan wheel is half concave ball shape, its universal rolling mechanism is made up of the longitudinal axis, transverse axis, bearing-type part and rolling body, rolling body is installed in the half concave ball shape shell, and be connected with it by transverse axis, be connected by the longitudinal axis that is provided with the bearing-type part between half concave ball shape shell and load-carrying body.The universal rolling of this cardan wheel is by realizing around the normal-running fit of longitudinal and transverse two S. A.s.Owing to be subjected to the effect of different directions power, when the rotation around transverse axis runs into the dead point, must get rid of by rotation around the longitudinal axis, when running into the dead point and do not rotate, destructive force is big, and cardan wheel is fragile, and service life is low.Common another kind of simple universal wheel is made up of shell and rolling body on the market, and the rolling body and the gap between shell of this cardan wheel are nonadjustable, and is little when big during friction force behind gap increase, the universal rolling weak effect, fragile, service life is low.
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part and provides a kind of follow-on low friction not have dead point adjustable slit top load spherical support universal rolling wheel, it is universal rolling and do not have the dead point easily,, adjustable gaps good to neutrality, and can reduce the internal friction resistance equably when rolling, improve load-carrying capacity, increase the service life.
The purpose of this utility model can realize by following measure:
The utility model (Fig. 1) is that a kind of low friction does not have dead point adjustable slit top load spherical support universal rolling wheel, it is made of shell and universal rolling mechanism, it is characterized in that: (1) its shell is provided with centre hole by the bottom, inwall is columnar internal thread sleeve 2, plug 4, bullet pad 5, plug 6 is formed, plug 4 and plug 6 adopt with internal thread sleeve 2 and are threaded, bullet pad 5 is located between plug 4 and the plug 6, (2) its universal rolling mechanism is a spherical support universal rolling mechanism, it is made up of with the identical steel ball 3 of a loop diameter on the steel ball 1 that is laid in a steel ball 1 of inserting in the internal thread sleeve 2 bottom centre holes, the diameter of steel ball 1 is less than the bottom centre bore dia of internal thread sleeve 2 diameter certainly greater than internal thread sleeve 2, the plane that is formed centrally in the steel ball 3 is higher than the summit of steel ball 1, and steel ball 3 is supported by plug 4.
Because universal rolling of the present utility model mechanism is a spherical support universal rolling mechanism, after steel ball 1 is stressed, disengage with internal thread sleeve 2, a circle steel ball 3 form to the good spherical support of neutrality in realize universal rolling, therefore have advantages such as low friction, no dead point, can effectively overcome and run into defectives such as the dead point can not be rotated, cardan wheel is fragile, service life is low in the prior art; Also because the utility model is formed the internal thread sleeve 2 of shell is threaded with plug 4, plug 6 employings and is provided with bullet pad 5, thereby the purpose that can reach adjustable gaps, pretension and prevent to become flexible, steel ball 3 is supported by the plug 4 that is threaded with internal thread sleeve 2, can improve effectively load-carrying capacity and service life, and can effectively overcome in the prior art meet the dead point roll be obstructed, defectives such as the gap is non-adjustable, little when big during friction force, universal rolling weak effect.
The drawing of the utility model accompanying drawing is described as follows:
Fig. 1 is the no dead point of the low friction of the utility model adjustable slit top load spherical support universal rolling wheel elevation cross-sectional view.
1. steel balls, 2. internal thread sleeves, 3. steel balls, 4. plugs, 5. bullet pads, 6. plugs among the figure
The utility model is described in further detail below with reference to drawings and Examples:
The low friction of adopting the utility model to make does not have dead point adjustable slit top load spherical support universal rolling wheel (Fig. 1) can realize universal rolling easily, plug 6 can be connected with load member easily, also can make and select for use corresponding material and size, form tandem product according to different demands.
In sum, the utility model compared with prior art has the following advantages:
1, adopts little, the no dead point of universal rolling mechanism frictional force, the high life of the good spherical support of centering;
2, the internal thread sleeve that forms shell is threaded with the plug employing and is provided with the bullet pad, and it is adjustable and can to have a gap
Pretension and anti-loosening, bearing capacity is big.
Claims (1)
1, a kind of low friction does not have dead point adjustable slit top load spherical support universal rolling wheel, and it is made of shell and universal rolling mechanism; It is characterized in that:
