Abstract
The utility model discloses a rolling wheel used for moving objects. The rolling wheel adopts no transverse shaft or vertical shaft, and the objects, instruments, equipment, devices or furniture needing to move can be moved and turned easily via installing the rolling wheel of the utility model. The rolling wheel is composed of a hollow steel ball, a seat support rack and a shell body.
Description
The utility model is a kind of roller devices required when being used for mobile article.
People are in daily life or activity in production, need move article or device with constant weight, as sofa berth, portable swivel chair, testing tool device, medical facilities instrument and cooker transport trolley and books transfer cart etc. all are equipped with 3-4 wheel, wherein 1-2 free rotation direction of the necessary energy of wheel.The wheel of this energy rotation direction, people are referred to as cardan wheel, so that rotate and move by desired direction.But the weight capacity of these cardan wheels is very limited, near surface bearing and bear and be easy to fracture the moment of flexure axle and disintegrate.According to the social market investigation, existing cardan wheel damage rate is up to 30%.Simultaneously, this cardan wheel is turning to when mobile, and its required rotary space is bigger, rotates or also very dumb when mobile, and in the less occasion of careat, it is more inconvenient to use.
In order to solve the deficiency of described inconvenience of joint and existing cardan wheel, the utility model design is proposed---a kind of nothing axle universal spherical roller that is referred to as, to replace existing cardan wheel.The utility model design-calculated feature is a hollow spherical surface body of steel, do not need as essential bolster on the wheel, mainly by having at least three points to contact with the hollow spherical surface body of steel, article or installation weight are delivered on the ground, when mobile, can also make any direction and rotate as requested and change of direction.
Accompanying drawing is the cutaway view that does not have axle universal spherical roller.
(1) is the bracket frame among the figure, and (2) are housings, and (3) are nylon cages, and (4) are connecting pieces, and (5) are steel balls, and (6) are felt pans, and (7) are hollow steel balls.
Bracket frame (1) directly be supported article, device or vehicle support stand and be connected, by the sheet steel drawing.It utilizes fastener and is supported article, device or vehicle support stand and joins and fuse.Every covering device has four usually, and some places also can be only with three, according to the weight size decision that is supported article, device or vehicle support stand.Bracket frame (1) bottom is connecting piece (4), and it will be half garden ball-shaped housing (2) and bracket frame (1) connects to one.Hollow steel ball (7) is stitched together after striking out half garden sphere by two with sheet steel, is placed in the cylinder barreling smooth burr free of spherome surface of make suring then.The shape of nylon cages (3) and housing (2) are similar, but the diameter of its spheroid is smaller, being furnished with minimum on the surface of nylon cages (3) is the steel ball acupuncture point of three circles, the rarest three the steel ball acupuncture points of a uppermost circle, be supported article so that place steel ball (5) and bear, the main weight of device or vehicle support stand.Also to place steel ball (5) in the steel ball acupuncture point of other several circles and slosh.Then, with nylon cages (3) and hollow steel ball (7) one lifting devices in housing (2), and impose the extruding necking down process with speciality tool housing (2) and hollow steel ball (7) are combined into one, make hollow steel ball (7) utilize steel ball (5) to contact and can freely rotate, do not come off and can not disintegrate with housing (2).
It is sturdy and durable that the shaftless Universal ball-like wheel of the utility model design has part few (comparing a few transverse axis and a longitudinal axis with existing universal wheel), the strong and big advantages such as (bigger three, four times than the supporting power of existing universal wheel) of loading capacity of beautiful and applicable property. Cost through adjusting this shaftless Universal ball-like wheel and existing universal wheel are similar.
Claims (4)
1, a kind of nothing axle universal spherical roller is characterized in that having a bracket frame (1), and housing (2), nylon cages (3) and hollow steel ball (7) are equipped with in bracket frame (1) bottom.
2,, it is characterized in that hollow steel ball (7) is struck out by sheet steel by two to be spliced after being the semisphere workpiece according to the no axle universal spherical roller of claim 1.
3, according to claim 1,2 no axle universal spherical roller, it is characterized in that hollow steel ball (7) in nylon cages (3) is sleeved on housing (2), housing (2) and hollow steel ball (7) are combined into one with the extruding necking down process.
4, according to the no axle universal spherical roller of claim 3, it is characterized in that disposing on the nylon cages (3) have at least three the circle steel balls (5), every circle has three steel balls (5) at least.
