Abstract
The utility model discloses a ball linear bearing comprising a fixing frame and balls. A plurality of groups of ball fixing grooves are evenly arranged along an axial direction inside the fixing frame, and each group of ball fixing groove is in a ring shape and evenly distributed. Moreover, one ball is arranged in each ball fixing groove. Preferably, the fixing frame is an elastic plastic injection part, and one side of the fixing frame is provided with an opening part extending along the axial direction. Moreover, two end portions of the fixing frame are provided with ring turning through parts protruding outward along a radial direction. More preferably, all the ball fixing grooves are in inner concaved forming structure. The ball linear bearing is simple in structure, low in cost, easy to install, good in stability, and strong in carrying ability.
Description
Technical field
The utility model relates to a kind of linear bearing, relates in particular to a kind of ball linear bearing, belongs to field of mechanical technique.
Background technique
At present, mostly the linear bearing that uses on the market is the structure of fixing frame+ball+outer ring (or inner ring), and its ball is fixed in the fixing frame groove, comes off to prevent one-sided ball.But in general, the wall thickness of this type of linear bearing is ball diameter+outer ring (or inner ring) wall thickness, and this makes bearing structure complicated.
The model utility content
The purpose of the utility model is to propose a kind of assembling that is easy to, good stability, and the high ball linear bearing of bearing capacity, thus overcome the deficiency of existing technology.
For realizing above-mentioned model utility purpose, the utility model has adopted following technological scheme:
A kind of ball linear bearing comprises fixing frame and ball, evenly is provided with plural groups ball fixed groove in the said fixing frame vertically, and each group ball fixed groove evenly distributes ringwise, and is equipped with a ball in each ball fixed groove.
Say that further said fixing frame is the elasticity moulding, the one of which side is provided with the opening portion that extends vertically.
Said fixing frame two end part are provided with the annular of radially outwards protruding and turn over all over portion.
Said ball fixed groove adopts the indent shaped structures.
The assembly process of this ball linear bearing is: apply certain outer force compresses to this linear bearing its external diameter is diminished; Again it is stretched in the pilot hole; Discharge external force then, then this linear bearing will be fixed in the pilot hole, penetrate a part in this linear bearing inside then and promptly accomplish assembling.
Compared with prior art, the utility model has the following advantages at least: simple in structure, be easy to assembly; And because coaxial the setting arranged balls more; The weight of bearing material is evenly distributed on many row's balls, has increased the stability of linear bearing, has improved the bearing capacity of linear bearing.
Description of drawings
Fig. 1 is the structural representation of ball linear bearing in the utility model one preferred embodiment.
Embodiment
Below in conjunction with an accompanying drawing and a preferred embodiment technological scheme of the utility model is done further explanation.
Consult Fig. 1; This preferred embodiment relates to a kind of ball linear bearing, comprises fixing frame 1 and ball 2, and three row's ball fixed grooves evenly are set in the said fixing frame 1 vertically; Each row's ball fixed groove evenly distributes along annular, is provided with a ball in each ball fixed groove.
Adopt this kind design, make this axis bearing not need to increase in addition inner ring or outer loop mechanism, outside the spinfunction of the normal bearing of decapacitation, be applicable to simultaneously also that the relative opening straight line moves and move relative to an axle straight line.
As a kind of preferred scheme, said fixing frame adopts cylinder type elasticity moulding, on its cylndrical surface opening is arranged; This opening can make the interior under external force external diameter of this linear bearing shrink simultaneously; Be convenient to assembling, after losing external force, this fixing frame attitude that can restore to the original state automatically again.
As another kind of preferred version, cylndrical surface, said fixing frame both sides is equipped with outside flange, and this flange can guarantee after the linear bearing assembling landing not to take place axially, and is stable with assurance function.
As another preferred version; Ball fixed groove in the said fixing frame is the indent shaped structures, can prevent effectively that the ball inboard and the outside from coming off, even without the outer ring and the protection of inner ring can not cause the ball landing yet; Guarantee that it is more convenient in assembling, use more stable.
The assembly process of this preferred embodiment is: this linear bearing is applied certain outer force compresses its external diameter is diminished, stretch in the pilot hole, discharge external force then, then this linear bearing will be fixed in the hole, and inside penetrates a part and promptly accomplishes assembling then.
This preferred embodiment can move axially when doing the circumference rotation after accomplishing assembling.
The foregoing description is merely the technological method and the thinking of explanation the utility model, and its purpose is to let the personage who is familiar with this technology can understand content of the utility model and enforcement according to this, but can not limit the protection domain of the utility model with this.All equivalences of being done according to the utility model spirit change or modify, and all should be encompassed within the protection domain of the utility model.
