The rolling channel of 30 both sides is to be symmetrical arranged relative to symmetry axis L；The present embodiment be on the head 31 of the slide rail 30 in this
Symmetry axis L both sides set on one rolling channel 312 and rolling channel 313, and respectively being rolled on this once in rolling channel 311, one respectively
Ditch 311 in the Z-direction position of the slide rail 30 higher than respectively in this rolling channel 312 in the Z-direction position of the slide rail 30；And respectively rolled in this
Dynamic ditch 312 is in the Z-direction position of the slide rail 30 higher than the respectively lower rolling channel 313 in the Z-direction position of the slide rail 30；And the present invention
Respectively on this rolling channel 311 and respectively in this rolling channel 312 is located at the first half on the head 31, and respectively the lower rolling channel 313 is located at
The lower half on head 31；
One sliding block 40, with a grooving 41, the sliding block 40 is slippingly set on the slide rail 30 with the grooving 41, and should
Correspondence respectively rolling channel 311 on this, respectively rolling channel 312 and respectively the position of the lower rolling channel 313 sets six rollings in this on grooving 41
Dynamic groove 411；And
Multiple balls 50, are rollably placed between the respectively rolling channel 411 and the rolling groove 311,312,313, and work as
When respectively the ball 50 is placed in the respectively rolling channel 311,312,313, two balls 50 in two rolling channels 311 on this are placed in
Center in the spacing in the Y-direction be one first ball centre-to-centre spacing d1；It is placed in two balls in two rolling channels 312 in this
50 center is one second ball centre-to-centre spacing d2 in the spacing in the Y-direction；And two be placed in the two lower rolling channels 313 should
The center of ball 50 is one the 3rd ball centre-to-centre spacing d3 in the spacing in the Y-direction；Neck width W2 be respectively smaller than this second
Ball centre-to-centre spacing d2 and the 3rd ball centre-to-centre spacing d3, the need for meeting structure design；And, because height pushes rigid linear rolling
The rigidity of pearl slide rail is relevant with its sectional area, and neck 32 is the minimum region of the sectional area of the slide rail 30, firm for influence structure
Property critically important region, to increase the rigidity of linear ball sliding rail containing, the present embodiment designs neck width W2 more than first rolling
Pearl centre-to-centre spacing d1, to obtain optimal rigid result；Certainly, as there is special space to limit on fruit structure, design makes the neck
The numerical value that width W2 is more than the diameter that the first ball centre-to-centre spacing d1 cuts the ball 50 also can obtain sub-optimal rigidity knot
Really；Wherein, the 3rd ball centre-to-centre spacing d3 is designed as more preferably with slightly larger, to avoid lower rolling channel 313 and neck 32 from producing manufacture
On interference, therefore design on, the 3rd ball centre-to-centre spacing d3 can be increased and make neck width W2 be less than the 3rd ball centre-to-centre spacing
D3 cuts the numerical value of the diameter of the ball for more preferably.
In addition, when respectively the ball 50 is placed in the respectively rolling channel 311,312,313, ball 50 of the invention is with rolling
Ditch 311,312,313 meets hypothesis and the definition of Hertzian contact theory (Hertz contact theory), then the ball 50 with
Each rolling channel 311,312,313 produces a contact point T respectively, the contact of the ball 50 or each rolling channel 311,312,313
There is a normal N by contact point T on face, respectively rolling channel 311 on this, respectively in this ball 50 of rolling channel 312 the normal N
The angle between the upper direction of Z-direction then defines a contact angle α respectively, and respectively rolling channel 311 on this, respectively rolling channel in this
The contact angle α of 312 balls 50 being in contact with it respectively is 20~70 degree, considers that contact angle α is less than 20 degree and can made from manufacture direction
The contact surface of ball 50 or each rolling channel 311,312,313 diminishes, and reduces the load-bearing capacity that contact surface can bear；Conversely
, if contact angle α is more than 70 degree ball 50 or each rolling channel 311,312,313 can be made to be reduced in the load-bearing capacity of Z-direction
And be unable to reach this hair height to be reached and push rigid purpose；More preferably, for avoid manufacture on it is unstable caused by
Problem, and improve the of the invention height to be reached and push rigid characteristic, contact angle α with 30~50 degree more preferably；And optimal design
Angle is 40 degree；In addition, should unanimously be considered from each ball 50 and 311,312 deflection after stress of each rolling channel, respectively should
Upper rolling channel 311 and respectively in this contact angle α of rolling channel 312 is preferable to be designed as equivalence；And, similarly, each lower rolling channel
Angle of the normal N of 313 ball 50 respectively between the lower direction of Z-direction is same to define a contact angle α, and respectively under this
The contact angle α for the ball 50 that rolling channel 313 is in contact with it is 20~70 degree, and 30~50 degree are that more preferably and 40 degree are optimal.
The structural configuration and feature of rigid linear ball slide rail are pushed for height of the present invention above, and is worth explanation first
It is, because respectively rolling channel 311,312,313 of the present invention is the both sides that are symmetricly set in the slide rail 30, the top of the slide rail 30
Top surface does not configure rolling channel, therefore can be saturating in the both sides difference of the slide rail 30 as shown in Figure 6 when grinding produces the slide rail 30
Side abrasive article A is crossed while carrying out disposable attrition process can complete, is not required to carry out top or the grinding in other directions again,
And production process can be simplified, production efficiency is improved, and create higher economic benefit；And known technology is also avoided using twice
The machining benchmark of manufacturing procedure is different, makes top surface and the rolling channel of side relative with error, and reduces the accurate of ball slide rail
The problem of spending.
And of the invention in terms of quiet rated load ability, ball total quantity, the entirety of quiet rated load numerical value and each row
The ball columns of ball slide rail is into positive correlation, and the present invention is overall altogether with six row balls, compared to general two row, four row
Ball slide rail can have higher quiet rated load；And the sectional area size of structure can significantly affect the rigidity of structure, this hair
It is bright especially to limit neck width W2 again while 50 columns of ball is increased and limit as described above, neck width W2 is made according to this not
Reason increases the columns of ball 50 and reduced width and influences the rigidity of the slide rail 30, and the present invention increases the columns of ball 50 and simultaneously tieed up simultaneously
Neck width W2 is held, and the rigidity of slide rail 30 can be improved really, extends life of product；And pushed for especially up to increase rigid
Effect, and lifting push the quiet rated load in direction, and the first half of the present invention on head 31 sets four rolling channels 311,312, and (both sides are each
Two rolling channels, therefore have four rolling channels), and two rolling channels 313 (as shown in Figure 4) are only set in the lower half on head 31, i.e., on this
Rolling channel 311 and rolled in this 312 ditches be located at the head 31 the first half, and the lower rolling channel 313 be located at head 31 lower half
Portion；The quiet rated load that refer to the present invention is clearly superior to the comparison datagram of two kinds of existing products as shown in fig. 7, in Fig. 7
Longitudinal axis table is the quiet rated load numerical value for pushing direction of the invention pushing the quiet rated load in direction, leftmost side strip A, and
Middle strip B is the quiet rated load numerical value for pushing direction of the general linear slide rail of same size, and rightmost side strip C is general
The logical quiet rated load numerical value for pushing direction for strengthening pushing linear slide rail, can learn that the present invention's pushes the quiet of direction by Fig. 7
Rated load numerical value is far above general linear slide rail, and the quiet rated load of linear slide rail is also pushed apparently higher than common reinforcement
Numerical value (comparison under the limitation of identical size).
Further, since the columns of the slide rail rigidity of ball slide rail also with steel ball is set into positive correlation, therefore in the present invention
It is set in the state of six row balls, there can be higher rigidity compared to the ball slide rail of general two row, four row, refer to this
Invention push and lateral rigidity value is clearly superior to the comparison datagram of two kinds of existing products as shown in figure 8, longitudinal axis table in Fig. 8
Linear ball sliding rail containing is pushing direction or lateral rigidity, and strip A is the values of stiffness of the linear slide rail of the present invention, and strip B is one
As linear slide rail values of stiffness, strip C is the existing values of stiffness of linear slide rail for strengthening pushing, and of the invention pushes the firm of direction
Property value be far above the linear slide rail of general same size, and substantially also above it is existing strengthen pushing linear slide rail push direction
Values of stiffness, and if assessed by lateral rigidity value, lateral rigidity value of the invention is not only far above general same size
Linear slide rail, and far above it is existing strengthen push linear slide rail values of stiffness (identical size limitation under comparison).
Furthermore, it is 20~70 degree that the present invention, which particularly configures each ball 50 and the contact angle α of rolling channel 312 angle, please
Coordinate refering to Fig. 9 show contact angle α of the present invention change with push and lateral quiet rated load datagram, the longitudinal axis in Fig. 9
The quiet rated load of table linear ball sliding rail containing, solid line (triangular data points) represents to push the quiet rated load in direction, and dotted line
(circular data point) represents lateral quiet rated load, although reduction contact angle α angle, which can be lifted, pushes the quiet specified of direction
Load, but be also relatively more greatly reduced lateral quiet rated load, Fig. 9 be shown in contact angle α angle be less than 20 degree with
Afterwards, the quiet rated load continuous decrease of side load, but push direction quiet rated load lifting effect slow down, similarly,
It is more than in contact angle α angle after 70 degree, pushes the quiet rated load continuous decrease in direction, but the quiet of side load specified is born
The effect of lotus lifting less, that is, contact angle α angle is less than 20 degree or during more than 70 degree, thinks increased quiet rated load simultaneously
Without substantially increase, the quiet rated load of other direction is caused to significantly reduce on the contrary, and general toter is slided for linear ball
The demand of rail, which generally has to have concurrently, pushes direction and lateral quiet rated load, thus in contact angle α angle design with 20~
70 degree are preferred；Furthermore, can see from the curve shown in Fig. 9, when contact angle α is 50 degree, push the quiet rated load in direction
It is approximately equal to lateral quiet rated load, and considering for the present invention is that lifting pushes rigidity, therefore to select contact angle α as less than 50
The quiet rated load that degree makes to push direction is more than lateral quiet rated load for more preferably, and again from lateral quiet rated load curve
From the point of view of, when contact angle α angle is 30 degree, lateral quiet rated load numerical value has reached its lateral quiet rated load most
More than half of big numerical value, that is, it is with suitable lateral quiet rated load, therefore, selection contact angle α angle is big
The effect for taking into account lateral quiet rated load can be reached in 30 degree, therefore is more than 30 degree in design with contact angle α angle
For more preferably, i.e., contact angle α angle is more preferably at 30~50 degree；And most preferred embodiment is to set contact angle α for 40 degree, in this shape
The quiet rated load in direction is pushed under state apparently higher than lateral quiet rated load, can significantly improve and push load-bearing capacity, and again
Ability with fine side load there is provided height pushes rigid characteristic, and satisfaction pushes the higher behaviour in service of workload demand.
