Abstract

The utility model discloses a simple ball bearing with raceway for single loop which is suitable for the situation of low loading, low speed rotation and low accuracy requirement. The utility model is in particular suitable for furniture and revolvable dining table. The simple ball bearing is made from the pressing of the rigid plastic. The one ferrule is pressed with a raceway, and the circumference of the other ferrule is uniformly provided with a plurality of ball and socket bases. Steel balls which are arranged at the inners of the ball and socket bases can rotate. When the bearing is in action, the steel balls can realize autorotation in the ball and socket bases, and the ball and socket bases can drive the steel balls to realize revolution along the raceway; thereby, the bearing has simple structure and low cost.

Description

Simple ball bearing with raceway

A kind of bearing is applicable to that load is little, and rotating speed is low, on the less demanding living utensil of running accuracy.

The conventional construction of general bearing is by inside and outside circle, the rolling element retainer, and four most compositions, inside and outside circle is equipped with raceway, not only rotation of rolling element during bearing working, and revolve round the sun along the Internal and external cycle raceway.Its material generally adopts Bearing Steel, makes through Overheating Treatment and strict machining, and it is big therefore to bear load, the running accuracy height, and fabricating cost is corresponding also high.

Continuous improvement along with people's life, some new-type furniture, living appliance constantly enter sphere of life, some furniture design one-tenth activity, some working surface will have some relative rotary motion such as the rotatable dining table that uses in dining room or the family, need the installed thrust bearing, if adopt traditional bearing,, be undoubtedly a kind of unnecessary waste with improving the cost of production of furniture.

The purpose of this utility model just provides a kind of simple in structure cheap, can be widely used in various low-loads, the bearing on the low-value product.

Task of the present utility model realizes by following approach.Rigid plastics, nylon or used for non-ferrous metal hot-cast or the method for colding pressing process in the bearing (on), outer (descend) encloses, wherein squeeze out raceway on the lasso, corresponding raceway position, the some ball and socket bases of another ring face garden Zhou Junbu, steel ball places in the ball and socket base, and can rotate in the nest seat.During bearing working, ball and socket base drives steel ball and revolves round the sun along raceway, and this structure makes the lasso of band ball and socket base also serve as the effect of retainer simultaneously, thereby reaches the simplification bearing structure, reduces the effect of bearing cost.

Fig. 1, Fig. 2, Fig. 3, Fig. 4 are embodiments of the present utility model, and label is wherein represented respectively:

1---enclosing 2 on the bearing---bearing figure below, 3---rolling element, label among Fig. 3: 4---regulate pad, label among Fig. 4: 4---wear-resistant gasket, 5---stop collar.

Fig. 1 is a simple embodiment, squeeze out the upper and lower circle of bearing with rigid plastics, the some ball and socket bases of circle garden Zhou Junbu on the bearing, the shape of ball-and-socket is the garden cylindricality, the steel ball major part is inserted in the nest seat and the energy rotation, in order to prevent that steel ball from coming off, with hot pressing mode extruding nest seat mouth steel ball is embedded, cooperate with the following circle that is pressed with raceway.

The shape of ball-and-socket can also be made the such sphere of Fig. 2.

Circle post hole, end face garden Zhou Junbu some steps garden on Fig. 3 middle (center) bearing, the big nose end of step hole has screw thread, steel ball is inserted in the macropore and is exposed partly from small bore end, and adjusting pad 4 screws off from the big nose end in post hole, garden pushes down steel ball, thereby can regulate the gap of steel ball in ball and socket base.

Fig. 4 is another embodiment, squeeze out on the bearing with rigid plastics, following circle, the some gardens of last circle garden Zhou Junbu cylindricality ball and socket base, put into wear-resistant gasket 4 at the bottom of the ball and socket base, wear-resistant gasket can be made plane or spherical female surface, Kong Chengyuan pylon scalariform in the middle of the metal stop collar 5 compacting garden cylindricalitys, steel ball is inserted in the position limit cycle from macropore, the part steel ball surface is exposed by small bore end, the metal stop collar 5 that steel ball is housed contacts with wear-resistant gasket 4 with the upper surface that ball and socket base garden post surface interference fit is pressed into the back steel ball, the lower surface exposed portions serve contacts with the raceway that bearing encloses down, on, following lasso lumps together forms a cover thrust-bearing.

Claims

1, a kind ofly be used for low carrying, low speed, running accuracy is less demanding, is specially adapted to the ball bearing on furniture and the lazy Susan, it is by Shang Quan, circle and rolling element are formed down.It is characterized in that: described go up circle or down circle have only and be pressed with raceway on the lasso, and some ball and socket bases of the corresponding raceway position garden Zhou Junbu of another lasso, steel ball place that its part steel ball surface that exposes contacts with the lasso roller surface in nip drum road in the ball and socket base.

2, its material of the described thrust ball bearing of claim 1 can adopt rigid plastics, nylon and non-ferrous metal.

3, the described thrust ball bearing of claim 1, ball and socket base wherein is the garden cylindricality, steel ball can not come off after inserting the nest seat.

4, the described thrust-bearing of claim 1, ball and socket base wherein can also be spherical, steel ball can not come off after inserting the nest seat.

5, the described thrust ball bearing of claim 1, ball and socket base wherein is embedded with wear-resistant gasket 4 and stop collar 5.
