Abstract
The invention discloses a ball linear bearing which comprises an opening retainer, a fixing base, a ball groove and balls, wherein the ball groove is formed in the inner wall of the opening retainer, and the balls are distributed in the ball groove; the opening retainer is formed by winding and molding metal-plastic composite boards; the fixing base is ring-type, is made of stainless steel and is fixedly arranged at the opening retainer in a sleeving manner; parts of the balls are exposed to the ball groove and are protruded toward the interior of the opening retainer, and a plurality of through holes are formed in the pipe wall of the fixing base. The ball linear bearing is high in strength, capable of bearing relatively high radial pressure and axial pressure, good in heat dissipation and long in service life.
Description
Technical field
The present invention relates to technical field of bearings, particularly relate to a kind of ball linear bearing.
Background technique
Linear bearing is applied in many industries such as electronic equipment, food machinery, package packing machine, medical machinery, textile manufacturing machine, machinery, instrument, automobile more and more widely at present.Linear bearing is a kind ofly to make unlimited straight-line system with straight-line transmitting moving axis is used in conjunction with, in prior art, there are various types of linear bearings, traditional linear bearing complex structure, not wear-resisting wiping, perishable, the working life of linear bearing is short, needs often maintenance and changes, and has increased cost of production.
Summary of the invention
The present invention is in order to solve the complex structure of prior art cathetus bearing, the problem of wear-resisting wiping not, provide a kind of simple in structure, the ball linear bearing that intensity is large, technological scheme of the present invention is: a kind of ball linear bearing, comprise opening retainer, fixed base, be located at the ball grooves of opening retainer inwall and be distributed in the ball in ball grooves, described opening retainer adopts the composite sheet coiling and molding of metal and plastics to make, described fixed base is circular shape, by stainless steel, made and fixedly sleeved on opening retainer, it is outstanding to the inside of opening retainer that a part for ball is exposed ball grooves.The tube wall of described fixed base is provided with some through holes.
Beneficial effect of the present invention is as follows: because opening retainer adopts the composite sheet coiling and molding of metal and plastics, make, and the circular shape fixed base that outside socket stainless steel is made, ball linear bearing intensity of the present invention is large, can bear larger radially, axial pressure, by some through holes are set on fixed base tube wall, be conducive to linear bearing heat radiation when work, and can keep linear bearing to be difficult for producing deformation, extended the working life of linear bearing.
Accompanying drawing explanation
Examples of the present invention will be described by way of reference to the accompanying drawings, wherein:
Fig. 1 is stereogram of the present invention;
Fig. 2 is the sectional view of Fig. 1.
Embodiment
Disclosed all features in this specification, or the step in disclosed all methods or process, except mutually exclusive feature and/or step, all can combine by any way.
Disclosed arbitrary feature in this specification, unless narration especially all can be replaced by other equivalences or the alternative features with similar object.That is,, unless narration especially, each feature is an example in a series of equivalences or similar characteristics.
Be illustrated in figure 1 a preferred embodiment of the present invention: a kind of ball linear bearing, comprise opening retainer 1, fixed base 2, be located at the ball grooves 3 of opening retainer inwall and be distributed in the ball 4 in ball grooves, opening retainer 1 adopts the composite sheet coiling and molding of metal and plastics to make, fixed base 2 is for circular shape, made and fixedly sleeved on opening retainer 1 by stainless steel, and it is outstanding to the inside of opening retainer 1 that a part for described ball 4 is exposed ball grooves 3.The tube wall of fixed base 2 is provided with some through holes 5.By some through holes are set on fixed base tube wall, be conducive to linear bearing heat radiation when work, and can keep linear bearing to be difficult for producing deformation, extended the working life of linear bearing.
The present invention in use, makes because opening retainer adopts the composite sheet coiling and molding of metal and plastics, and the circular shape fixed base made of outside socket stainless steel, and ball linear bearing intensity of the present invention is large, can bear larger radially, axial pressure.
The present invention is not limited to aforesaid embodiment.The present invention expands to any new feature or any new combination disclosing in this manual, and the arbitrary new method disclosing or step or any new combination of process.
