Abstract
The utility model discloses a shaftless universal rolling wheel used for moving objects, which comprises a ball cover, rolling balls partially arranged in the ball cover and a top cover arranged on the ball cover. The rolling balls in the ball cover not only can ensure a rolling ball can roll toward any direction, but also can ensure moving objects can be static when the objects need to be fixed. The shaftless universal rolling wheel has the characteristics of flexible and easy rolling, large capability for bearing large pressure and impact, convenient manufacture and maintenance, and the shaftless universal rolling wheel is not easy to be damaged.
Description
The utility model is a kind of tourelle required when being used for mobile article.
That sells in the market has a cardan wheel, because the moment of flexure effect that it is produced by object gravity and ground support reaction, is easy to distortion and damages, and rotate also dumb.In addition, that sells on the market also has several nothings axle cardan wheels (for example CN87202299), though be not subjected to the moment of flexure effect, and increased ball between spin and the housing, but these structures are because ball can not form circulating rolling by analysis, be still cliding friction, so resistance is big, spin is easy to wear.
The purpose of this utility model is to adopt not wait dark raceway structure in universal rolling wheel, and ball has been realized circulating rolling, thereby has guaranteed that ball all is pure rolling in any direction; And the utility model can also can be checked motionless when not needing to move.
Accompanying drawing is a cutaway view of the present utility model.
With reference to accompanying drawing, the utility model comprises that a upper end is a cylinder, the lower end is the ball cover (5) of circular cone, its part places interior spin (6) of ball cover (5) and the top cover (2) on the ball cover (5), top cover (2) can be screwed below being moved article, top cover (2) is connected with raceway seat (3) below by rivet (1), do not wait dark raceway hole inboard even being furnished with of raceway seat (3), in each hole ball (4) is housed all, and make spin (6) contact with ball (4), ball cover (5) upper end column part upper punch has the pitting of symmetry, it can rotate in the thread groove on top cover (2) cylindrical, thereby make on the ball cover (5), move down, realize braking or loosen spin.
This shows that do not wait in the dark raceway hole because ball of the present utility model is contained in, ball has been realized circulating rolling, so frictional resistance is little, it is flexible, light to roll; Since ball cover can about Mobile, realize braking or loosen spin, so when being moved article fixedly the time, only needing gently, the turn ball cover gets final product; And the utility model also do not kept existing universal rolling wheel not to be subjected to moment of flexure, can to bear big pressure and impact, and is fragile, make and maintenance characteristics very easily all.
Claims (2)
1. one kind is not had the axle universal rolling wheel, comprise a ball cover (5), its part places interior spin (6) of ball cover (5) and the top cover (2) on the ball cover (5), ball (4) in the ball cover, feature of the present utility model is, be threaded groove on the cylindrical of said top cover (2), be connected with raceway seat (3) below the top cover (2), inboard even being furnished with of raceway seat (3) do not waited dark raceway hole, in each hole ball (4) is housed all, and make spin (6) contact with ball (4), said ball cover (5) is that a upper end is a cylinder, the lower end is the housing of circular cone, the pitting that ball cover (5) upper end column part upper punch has symmetry can rotate in the thread groove on top cover (2) cylindrical.
2. nothing axle universal rolling wheel according to claim 1 is characterized in that said top cover (2) and raceway seat (3) can pass through rivet (1) and connect.
