Description
Technical field
This utility model relates to linear bearing field, particularly relates to a kind of double flange linear bearing.
Background technology
Linear bearing is a kind of linear motion system, for rectilinear path and cylinder axis with the use of.At present, linear bearing mostly is plastic material, and the ball within linear bearing mostly is linear array, and therefore to have friction little and more stable for linear bearing, does not changes with bearing speed, can obtain high steadily the moving along a straight line of highly sensitive, precision.But, current linear bearing shock loading ability is poor, and bearing capacity is the most poor, and when high-speed motion, vibration and noise are bigger.
Utility model content
This utility model to solve the problem that above-mentioned prior art exists, it is provided that a kind of double flange linear bearings, it is possible to utilizes gap buffer to improve shock loading ability and the bearing capacity of linear bearing.
This utility model solve its technical problem use technical scheme: this pair of flange linear bearing, including bearing holder (housing, cover), the flange that is fixed on bearing holder (housing, cover) end, linear bearing is installed in bearing holder (housing, cover), ball it is arranged at intervals with on linear bearing, the two ends of bearing holder (housing, cover) inwall are provided with draw-in groove, it is provided with in draw-in groove and linear bearing two ends are carried out spacing snap ring, be provided with gap between two ends and the snap ring of linear bearing, sealing ring is installed outside snap ring.Ball is arranged for interval, high-speed motion produced collision when avoiding linear array, the vibration produced when effectively alleviating linear bearing high-speed motion and noise, it is provided with gap between two ends and the snap ring of linear bearing, the high-speed motion of linear bearing is not only played cushioning effect by gap, improve the shock loading ability of linear bearing, and the uniform force of each ball when the setting in gap makes linear bearing high-speed motion, improve the bearing capacity of linear bearing.
In order to the most perfect, flange has a pair and is separately fixed at the two ends, left and right of bearing holder (housing, cover).Setting up of flange, adds the fastness that workpiece is fixing.
The most perfect, one of them flange is structure as a whole with one end of bearing holder (housing, cover), and the other end of bearing holder (housing, cover) is provided with embedded groove, and another flange sleeve is on embedded groove.One of them flange and bearing holder (housing, cover) integrative-structure, structure is more firm, and another flange sleeve, on embedded groove, can be installed as required.
The most perfect, linear bearing uses metal to make.Linear bearing uses metal to make more firm than plastics are made.
This utility model has the advantages that: this utility model reasonable in design, ball is arranged for interval, high-speed motion produced collision when avoiding linear array, the vibration produced when effectively alleviating linear bearing high-speed motion and noise, it is provided with gap between two ends and the snap ring of linear bearing, not only the high-speed motion of linear bearing is played cushioning effect, improve the shock loading ability of linear bearing, and the uniform force of each ball when making linear bearing high-speed motion, improve the bearing capacity of linear bearing.Setting up of flange, adds the fastness that workpiece is fixing, one of them flange and bearing holder (housing, cover) integrative-structure, and structure is more firm, and another flange sleeve, on embedded groove, can be installed as required.It is more more firm than plastics are made that linear bearing uses metal to make, and improves service life, is conducive to promoting the use of.

Description of reference numerals: bearing holder (housing, cover) 1, flange 2, linear bearing 3, ball 4, draw-in groove 5, snap ring 6, gap 7, sealing ring 8, embedded groove 9.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings:
Referring to the drawings: double flange linear bearings in the present embodiment, including bearing holder (housing, cover) 1, the flange 2 that is fixed on bearing holder (housing, cover) 1 end, it is characterized in that: linear bearing 3 is installed in bearing holder (housing, cover) 1, ball 4 it is arranged at intervals with on linear bearing 3, the two ends of bearing holder (housing, cover) 1 inwall are provided with draw-in groove 5, it is provided with in draw-in groove 5 and linear bearing 3 two ends are carried out spacing snap ring 6, be provided with gap 7 between two ends and the snap ring 6 of linear bearing 3, sealing ring 8 is installed outside snap ring 6.Ball 4 is arranged for interval, high-speed motion produced collision when avoiding linear array, the vibration produced when effectively alleviating linear bearing 3 high-speed motion and noise, it is provided with gap 7 between two ends and the snap ring 6 of linear bearing 3, the high-speed motion of linear bearing 3 is not only played cushioning effect by gap 7, improve the shock loading ability of linear bearing 3, and the uniform force of each ball 4 when the setting in gap 7 makes linear bearing 3 high-speed motion, improve the bearing capacity of linear bearing 3.Flange 2 has a pair and is separately fixed at the two ends, left and right of bearing holder (housing, cover) 1.Setting up of flange 2, adds the fastness that workpiece is fixing.One flange 2 is structure as a whole with one end of bearing holder (housing, cover) 1, and the other end of bearing holder (housing, cover) 1 is provided with embedded groove 9, and another flange 2 is enclosed within embedded groove 9.One of them flange 2 and bearing holder (housing, cover) 1 integrative-structure, structure is more firm, and another flange sleeve 2, on embedded groove 9, can be installed as required.It is more firm than plastics are made that linear bearing 3 uses metal to make.
During work, workpiece drives linear bearing 3 high-speed motion, it is provided with gap 7 between two ends and the snap ring 6 of linear bearing 3, not only the high-speed motion of linear bearing 3 is played cushioning effect, improve the shock loading ability of linear bearing 3, and the uniform force of each ball 4 when making linear bearing 3 high-speed motion, improve the bearing capacity of linear bearing 3, owing to ball 4 is arranged for interval, high-speed motion produced collision when avoiding linear array, so the vibration produced when can effectively alleviate linear bearing 3 high-speed motion and noise.
This utility model reasonable in design, ball 4 is arranged for interval, high-speed motion produced collision when avoiding linear array, the vibration produced when effectively alleviating linear bearing 3 high-speed motion and noise, due to ball 4 and bearing holder (housing, cover) 1 point cantact, ball 4 rolls with minimum frictional resistance, therefore linear bearing 3 have friction little, and more stable, do not change with bearing speed, steady linear motion highly sensitive, that precision is high can be obtained.It is provided with gap 7 between two ends and the snap ring 6 of linear bearing 3, not only the high-speed motion of linear bearing 3 is played cushioning effect, improve the shock loading ability of linear bearing 3, and the uniform force of each ball 4 when making linear bearing 3 high-speed motion, improve the bearing capacity of linear bearing 3.Setting up of flange 2, adds the fastness that workpiece is fixing, one of them flange 2 and bearing holder (housing, cover) 1 integrative-structure, and structure is more firm, and another flange 2 is enclosed within embedded groove 9, can install as required.It is more more firm than plastics are made that linear bearing 3 uses metal to make, and improves service life, is conducive to promoting the use of.
Although this utility model is by being shown and described with reference to preferred embodiment, but, those skilled in the art are it is to be appreciated that in the range of claims, can the various change made in form and details.
